Image data in frame units is sometimes referred to as ultrasound image data or frame image data. The image processing unit 15 sequentially outputs the image data generated as described above to the display control unit 16 under the control of the control unit 18 .

Under the control of the control unit 18, the display control unit 16 converts the image data received from the image processing unit 15 into an image signal for display, and outputs the image signal to the display unit 17 (display body unit 171).

FIG. 2 is a front view showing the display main unit 171 and the operation input unit 11 before and after rotation about the rotation axis R1. FIG. 3A is a side view showing the display section 17 and the operation input section 11 before rotation. FIG. 3B is a side view showing the display section 17 and the operation input section 11 with the display body section 171 tilted. FIG. 4A is a side view showing the display section 17 and the operation input section 11 after the pivot rotation. FIG. 4B is a side view showing the display unit 17 and the operation input unit 11 with the tilt of the display body 171 restored. FIG. 5 is a front view showing the display section 17 and the operation input section 11 in state ST1. FIG. 6 is a front view showing the display section 17 and the operation input section 11 in state ST2.

As shown in FIG. 2, in the display main unit 171 and the operation input unit 11 of the ultrasonic diagnostic apparatus 100, the rotation axis of the pivot rotation arranged on the display surface of the display main unit 171 is indicated by a circle with a cross mark. , the axis of rotation is R1. That is, the display main body 171 is pivotally rotated about the rotation axis R1. More specifically, the state of the display main body 171 indicated by the solid line is rotated by -90° about the rotation axis R1 to the state of the display main body 171 indicated by the two-dot chain line. The state (rotational position) of the display main body 171 indicated by the solid line is assumed to be the state ST1 in which the display main body 171 faces sideways (the long side is in the horizontal direction (y-axis direction)) as the state of the rotation reference position. The state of the position of the display main body 171 is assumed to be a state ST2 in which the display body 171 is vertically oriented (the long side is in the vertical direction (z-axis direction)). In addition, it is also possible to pivot the display main body 171 from the state ST2 to the state ST1 in the reverse rotation direction about the rotation axis R1.

As described above, in the pivot rotation of the display body 171 about the rotation axis R1, the clockwise rotation angle is represented by +, and the counterclockwise rotation angle is represented by -. Also, as shown in FIG. 2, the x-, y-, and z-axes are taken, and the same x-, y-, and z-axes are taken in other drawings as appropriate. Also, the center point of the display screen of the display body 171 is assumed to be the center point CP1.

In the state ST1, the length (width) in the horizontal direction (y-axis direction) of the side e1 as the long side of the display main body 171 (display panel 17a) is defined as the length W, and the display main body 171 (display panel 17a) 17a), the length (height) in the vertical direction (z-axis direction) of side e2 as the short side is assumed to be length H (<W). In the state ST1, the lower left corner point O of the yz plane of the display main body 171 is the origin, the length of the long side in the y-axis direction from the corner point O to the rotation axis R1 is the length A1, and the rotation axis Let length A2 be the length of the short side up to R1 in the z-axis direction. End point O is a common end point of sides e1 and e2. Also, length B=H−A2 and length C=W−A1.

In the state ST1, the rotation axis R1 is arranged and set substantially above the line L1 of the display body portion 171 . The line L1 is a line segment of z=y with the lower left corner point O of the display body 171 as the origin. Further, the horizontal (y-axis direction) center line of the side e1 of the display body 171 is defined as a center line M1, and the vertical (z-axis) center line of the side e2 of the display body 171 is defined as a center line M2. . Note that the mark of the rotation axis such as the rotation axis R1 of the display main body 171 and the center lines M1 and M2 are not displayed on the display screen.

The purpose of the arrangement of the rotation axis R1 in the present embodiment is to rotate the display main body 171 in the state ST1 by -90° to make the display main body 171 in the state ST2. The position of the lower side (edge in the -z direction) of (the display screen of) the portion 171 does not change (the distance from the operation input portion 11 is substantially the same). Therefore, A1 and A2 do not necessarily have to match, and 0≤A1≈A2≤H. At this time, for example, if |A1-A2|≤H/8, the above object can be achieved.

Here, a device configuration for rotating the display main unit 171 in the state ST1 to the state ST2 will be described. 3A and 5 show the display section 17 and the operation input section 11 corresponding to the display body section 171 in the state ST1. As shown in FIGS. 3A and 5, the support portion 172 of the display portion 17 has a support 17c, a hinge 17d, a protrusion 17e, a support 17f, and a rotating portion 17g.

The support 17c is a support column that is fixedly connected to the operation input unit 11, extends in the +z direction, and supports the display body 171 and the like. The hinge 17d is a movable portion that is installed at the tip of the support 17c in the +z direction and that adjusts the degree of inclination (tilt angle φ (FIG. 3B)) of the display panel 17a with respect to the support 17c. is a protrusion that is fixedly installed on the support 17c, extends in the +x direction, and is fitted to the rotating portion 17g.

The support 17f is a support that is fixedly installed on the hinge 17d and supports the display main body 171 so as to be pivotally rotatable about the rotation axis R1. The rotating portion 17g has guide holes 17g1 and 17g2, and is fixedly installed on the back surface of the display main body portion 171 so as to be pivotally rotatable together with the display main body portion 171. A member into which the projection portion 17e is fitted. is. The guide hole 17g1 is a hole into which the protrusion 17e is fitted in the state ST1. The guide hole 17g2 is a hole into which the protrusion 17e is fitted in the state ST2.

As shown in FIGS. 3A and 5, in the display unit 17 in the state ST1, the display main body 171 is not tilted and stands upright in the z-axis direction, the tilt angle φ=0°, and the projection 17e. is fitted into the guide hole 17g1, and the display main body 171 is locked so as not to be pivotally rotated. If the rotating portion 17g were not provided, the display body portion 171 would come into contact with the operation input portion 11 when the display body portion 171 pivots about the rotation axis R1. However, since there is the rotating portion 17g and the protrusion 17e is fitted in the guide hole 17g1, the display main body portion 171 is locked so as not to pivot.

Then, as shown in FIG. 3B, the operator manually tilts the display main unit 171 so that the tilt angle φ is a predetermined angle (>0° and threshold angle for unlocking the locked state). ) above. The positional state of the display unit 17 and the operation input unit 11 is assumed to be state ST3. In the state ST3, the protrusion 17e is pulled out of the guide hole 17g1 and unlocked, so that the display main body 171 can be pivotally rotated about the rotation axis R1, and the display main body 171 is connected to the operation input section 11 during rotation. No interference (no contact) unlocked state.

Then, as shown in FIG. 4A, the operator manually rotates the display body 171 about the rotation axis R1 by −90° while maintaining the tilt angle φ from the state ST3. The positional state of the display unit 17 and the operation input unit 11 is assumed to be state ST4. In states ST3 and ST4, the protrusion 17e passes through the portion indicated by the dotted line in FIG. 5 during the pivotal rotation.

Then, as shown in FIGS. 4B and 6, the operator manually moves the display main body 171 toward the support 17c while maintaining the rotation angle of the pivot rotation of the display main body 171 from the state ST4. and stand upright, and set the tilt angle φ to 0° to enter the state ST2. In state ST2, the protrusion 17e is fitted into the guide hole 17g2, and the display panel 17a is locked so as not to pivot.

Thus, the protrusion 17e and the rotating portion 17g are used as a lock mechanism. This lock mechanism prevents the pivotal rotation of the display body 171 when the tilt angle φ is less than a predetermined angle, and when the tilt angle φ is equal to or greater than the predetermined angle, the display is disabled. The lock is released so that the body portion 171 can be pivotally rotated. In addition, the lock mechanism unit is configured to rotate the display main body 171 when the rotation angle of the pivot rotation of the display main body 171 becomes a preset predetermined angle (rotation angle corresponding to the positions of the guide holes 17g1 and 17g2). to lock.

Further, the position of the rotation axis of the pivot rotation of the display main unit 171 may be changed by a setting person, an operator, etc. before shipment of the ultrasonic diagnostic apparatus 100 from the factory, before installation at an installation location after shipment, during use after installation, and the like. can be changed as appropriate.

Next, with reference to FIGS. 7A to 10, examples of different positions of the rotational axis of the pivot rotation of the display body 171 of the display unit 17 of the ultrasonic diagnostic apparatus 100 of the present embodiment will be described. . FIG. 7A is a front view showing the display main unit 171 and the operation input unit 11 in state ST6. FIG. 7B is a front view showing the display main unit 171 and the operation input unit 11 in state ST5. FIG. 7C is a front view showing the display main unit 171 and the operation input unit 11 in state ST7. FIG. 8A is a front view showing the display main unit 171 and the operation input unit 11 in state ST9. FIG. 8B is a front view showing the display main unit 171 and the operation input unit 11 in state ST8. FIG. 8C is a front view showing the display main unit 171 and the operation input unit 11 in state ST10. FIG. 9 is a flowchart showing screen setting processing. FIG. 10 is a diagram showing the ultrasonic diagnostic apparatus 100, examination table EX1, and subject SU1 in state ST9.

An example will be described in which the rotation axis for pivoting the display main body 171 of the display unit 17 is arranged as the rotation axis R2 at the intersection of the line L1 and the center line M1 as another position on the line L1 in FIG. That is, the rotation axis R2 is an example where A=W/2 when A1≈A2=A.

The positions and display states of the display main unit 171 and the operation input unit 11 shown in FIGS. 7A, 7B, and 7C are assumed to be states ST6, ST5, and ST7, respectively. First, the state ST5 is a reference state of pivot rotation about the rotation axis R2 with the display main body 171 turned sideways. A state ST6 is a state in which the display body 171 is pivotally rotated by −90° about the rotation axis R2 from the state ST5. A state ST7 is a state in which the display main body 171 is pivotally rotated by +90° about the rotation axis R2 from the state ST5.

On the rotation axis R1, in two states ST1 and ST2, the position of the lower side of the display body 171 (display screen of the display panel 17a) (the distance from the operation input unit 11) is constant (approximately) before and after the pivot rotation. the same). On the other hand, on the rotation axis R2, the position of the lower side of the display body 171 (distance from the operation input unit 11) is constant (substantially the same) before and after the pivot rotation in the three states ST5, ST6, and ST7. is.

For example, in state ST5, the horizontal screen 300 is displayed on the display panel 17a of the display body 171, and in states ST6 and ST7, the vertical screen 310 is displayed on the display panel 17a. A screen 300 includes an ultrasound image 301 , an operation display area 302 and a toolbar 303 . An ultrasound image 301 is an ultrasound image of a subject scanned by the ultrasound diagnostic apparatus 100 . The operation display area 302 is an area for displaying various operation buttons for receiving touch input from the operator on the touch panel 17b, various information such as the status of the ultrasonic image 301, and the like. A toolbar 303 is an area for displaying information such as current date and time information. Screen 310 includes an ultrasonic image 301 , an operation display area 302 , and a toolbar 303 , similar to screen 300 .

On the screen 300, a toolbar 303 is arranged on the upper side of the display screen of the display body 171 (display panel 17a), and an ultrasonic image 301 and an operation display area 302 are located on the left side of the display screen of the display body 171. , is located on the right side. On the screen 310, the toolbar 303 is arranged on the upper side of the display screen of the display body 171, and the ultrasonic image 301 and the operation display area 302 are arranged above and below the display screen of the display body 171, respectively. It is

In states ST6 and ST7, the distance between the operation input unit 11 and the operation display area 302 is relatively short, and the operator can easily perform various operations (operation input on the operation input unit 11, touch input on the operation display area 302). can be done. However, in state ST5, the distance between the operation input unit 11 and the operation display area 302 is relatively long, and there is a possibility that the operator cannot easily perform various operations.

Therefore, there is a configuration in which the rotation axis of the pivot rotation of the display main body 171 is set to the rotation axis R3 shown in FIGS. 8(a) to 8(c). The rotation axis R3 is arranged at the intersection of the line L1 in FIG. 2 and the center line M2. That is, the rotation axis R3 is an example where A=H/2 when A1≈A2=A.

The positions and display states of the display main unit 171 and the operation input unit 11 shown in FIGS. 8A, 8B, and 8C are assumed to be states ST9, ST8, and ST10, respectively. First, the state ST8 is a reference state of pivot rotation about the rotation axis R3 with the display panel 17a oriented vertically. A state ST9 is a state in which the display panel 17a is pivotally rotated by −90° about the rotation axis R3 from the state ST8. A state ST10 is a state in which the display panel 17a is pivotally rotated by +90° about the rotation axis R3 from the state ST8.

Similarly to the rotation axis R2, in the three states ST8, ST9, and ST10, the position of the lower side of (the display screen of) the display main unit 171 (the display screen of the display main unit 171) before and after the pivot rotation. distance) is constant (substantially the same).

Now, with reference to FIG. 9, screen setting processing executed by the ultrasonic diagnostic apparatus 100 in which the rotation axis R3 is set will be described. In the ultrasonic diagnostic apparatus 100, for example, triggered by input of an instruction to execute ultrasonic image display processing via the operation input unit 11, the control unit 18 sets the screen according to the screen setting program stored in the ROM. Execute the setting process. Ultrasonic image display processing is performed in the ultrasonic diagnostic apparatus 100 by generating live ultrasonic image data through the transmission and reception of ultrasonic waves to and from the subject by the ultrasonic probe 2 and displaying the data on the display main unit 171 (display panel 17a). ), and is executed in parallel with the screen setting process.

As shown in FIG. 9, first, the control unit 18 acquires the rotation angle of the pivot rotation about the rotation axis R3 of the display main unit 171 (the rotation angle based on the state ST8) from the detection unit 19 (step S11).

Then, the control unit 18 determines whether or not the rotation angle acquired in step S11 is 0° (step S12). If the rotation angle is 0° (step S12; YES), the state is ST8, and the control unit 18 sets the screen 310 corresponding to the rotation angle=0° and displays it on the display body 171 (display panel 17a). (step S13), and the process proceeds to step S11.

If the rotation angle is not 0° (step S12; NO), the control unit 18 determines whether or not the rotation angle acquired in step S11 is -90° (step S14). If the rotation angle is −90° (step S14; YES), the state is ST9, and the control unit 18 sets the screen 300 corresponding to the rotation angle=−90°, and displays the main display unit 171 (display panel 17a). is displayed (step S15), and the process proceeds to step S11.

If the rotation angle is not -90° (step S14; NO), the control unit 18 determines whether the rotation angle acquired in step S11 is +90° (step S16). If the rotation angle is not +90° (step S16; NO), the process proceeds to step S11. If the rotation angle is +90° (step S16; YES), the state is ST10, and the control unit 18 sets the screen 320 corresponding to the rotation angle of +90° and displays it on the display body 171 (display panel 17a). (step S17), and the process proceeds to step S11.

As shown in FIG. 8C, the screen 320 includes an ultrasound image 301, an operation display area 302, and a toolbar 303, similar to the screens 300 and 310. FIG.

On the screen 320, the toolbar 303 is arranged on the upper side of the display screen of the display body 171 (display panel 17a), and the ultrasonic image 301 and the operation display area 302 are respectively displayed on the display body 171 (display panel 17a). are located on the right and left sides of the display screen. In this manner, the screens 310 and 320 have the ultrasonic image 301, the operation display area 302, and the like, except for the toolbar 303, which are horizontally reversed.

Therefore, as indicated by the double arrows in FIGS. 8A to 8C, the distance between the operation input unit 11 and the operation display area 302 is relatively short in any of the states ST8, ST9, and ST10. , the operator can easily perform various operations (operation input of the operation input unit 11, touch input of the operation display area 302).

As shown in FIG. 10, consider a case where a subject SU1 is placed on an examination table EX1, and an ultrasonic diagnostic apparatus 100 is arranged beside the examination table EX1. In this case, even if it is difficult to move the ultrasonic diagnostic apparatus 100, the operator rotates the display main unit 171 by −90° about the rotation axis R3 to bring it to the state ST9, and the screen 300 is displayed by the screen setting process. By being displayed on the panel 17a, the operator can see that the operation input unit 11 and the operation display area 302 are on the right side opposite to the examination table EX1 and the distance between them is short. And the operation display area 302 can be operated and input easily. Further, the display main body 171 can be slid to a preferable position on the subject side only by pivoting the display main body 171 without moving the ultrasonic diagnostic apparatus 100 .

As described above, according to the present embodiment, the ultrasonic diagnostic apparatus 100 includes the side e1 as the first side having the length W as the first length and the second side adjacent to the side e1 and shorter than the length W. and a side e2 as a second side with a length H as a length of 2, and a display main body 171 having a display surface. Axis of rotation R1 is arranged at positions (positions on line L1) of A1 and A2 (A1≈A2) having substantially the same third length on each side from common end point O of sides e1 and e2. ing.

Therefore, there is no need to provide a plurality of rotating shafts or a mechanism for moving the rotating shafts, and the display main body 171 pivots around the rotating shaft R1 (for example, -90° pivot rotation from state ST1 to state ST2). With a simple configuration, the position of the lower side (in the z-axis direction) of the display main body 171 can be easily made approximately the same before and after the display main body 171 pivots.

Also, the length A (=A1≈A2) is the length W/2 (the rotation axis R2). Therefore, for example, in the three states ST5, ST6, and ST7, the position of the lower side (in the z-axis direction) of the display main body 171 can be substantially the same before and after the display main body 171 rotates. Furthermore, in the pivot rotation reference (rotation angle=0°) of the display main body 171, the positions of the rotation axis R2 and the center point CP1 of the display main body 171 in the horizontal direction (y-axis direction) can be substantially the same. .

Also, the length A (=A1≈A2) is the length H/2 (rotational axis R3). Therefore, for example, in the three states ST8, ST9, and ST10, the position of the lower side (in the z-axis direction) of the display main body 171 can be substantially the same before and after the display main body 171 rotates. In particular, in states ST9 and ST10, the display body 171 can be slid in the lateral direction (y-axis direction) (for example, toward the subject) only by pivoting about the rotation axis R3 without providing a slide mechanism. . Furthermore, in the pivot rotation reference (rotation angle=0°) of the display main body 171, the positions of the rotation axis R3 and the center point CP1 of the display main body 171 in the horizontal direction (y-axis direction) can be substantially the same. .

In addition, the ultrasonic diagnostic apparatus 100 includes a detection unit 19 that detects the rotation direction and the rotation angle as the rotation state of the pivot rotation of the display main unit 171, and the detected rotation direction and the rotation angle of the pivot rotation of the display main unit 171. Correspondingly, a control unit 18 for changing the layout of the screen displayed on the display main unit 171 is provided. Therefore, considering the distance between the operation display area 302 and the operation input unit 11, the layout of the screen can be made easy for the operator to view and operate.

Specifically, the control unit 18 sets the operation display area 302 as a first area for displaying information about the ultrasonic image or receiving touch input before and after the pivot rotation as the layout of the screen of the display main unit 171. , is arranged at a position close to the operation input unit 11 that receives the operation input. More specifically, the control unit 18 controls the screen 300 for rotating the display main body 171 clockwise by -90 degrees from the reference position of the rotation of the display main body 171, and the screen 300 for rotating the display main body 171 clockwise. The screen 320 corresponding to +90° pivot rotation is mirror-reversed. Therefore, the distance between the operation display area 302 and the operation input unit 11 is shortened, and the operator can easily view and operate the screen.

In addition, the control unit 18 makes the screen 300 corresponding to the −90° clockwise pivot rotation of the display main unit 171 and the screen 320 corresponding to the +90° clockwise pivot rotation of the display main unit 171 non-reversible. It has a toolbar 303 as an inversion area. Therefore, the visibility of the toolbar 303 can be maintained as it is, and the distance between the operation display area 302 and the operation input unit 11 is shortened, so that the operator can easily view and operate the screen.

Also, the position of the rotation axis of the display body 171 can be changed. Therefore, the manufacturer or the operator can appropriately change the position of the rotation axis of the display main body 171 before the ultrasonic diagnostic apparatus 100 is shipped from the factory, before it is installed at the installation site, or during use. The screen can be visually recognized and operated.

The ultrasonic diagnostic apparatus 100 also includes a support portion 172 that supports the display body portion 171 so as to be pivotally rotatable about the rotation axis R1. The support portion 172 includes a support 17c that supports the display main body 171, a hinge 17d as an adjusting portion that adjusts the tilt angle φ of the display main body 171 with respect to the extending direction (z-axis direction) of the support 17c, and a tilt angle. When the angle φ is less than a preset first angle (predetermined angle), the pivot rotation of the display body 171 is locked, and when the tilt angle φ is equal to or greater than the first angle. , and a lock mechanism portion (protruding portion 17e, rotating portion 17g) for unlocking the pivot rotation of the display main body portion 171 . Therefore, with a simple configuration, the display main body 171 interferes with the operation input unit 11 or the like during the pivot rotation of the display main body 171 when the display main body 171 is tilted and the tilt angle φ is equal to or greater than the first angle. The position of the lower side of the display main body 171 can be more easily made approximately the same before and after the pivot rotation.

In addition, the lock mechanism portion (projection portion 17e, rotating portion 17g) is configured so that the rotation angle of the pivot rotation of the display main body portion 171 is set to a preset second angle (rotation angle corresponding to the positions of the guide holes 17g1 and 17g2). In this case, the pivot rotation of the display main body 171 is locked. Therefore, when the rotation angle of the pivot rotation of the display main body 171 becomes the desired second angle, the pivot rotation of the display main body 171 can be reliably prevented.

(First modification)
A first modification of the above embodiment will be described with reference to FIGS. 11(a) to 12(c). FIG. 11A is a side view showing the display section 17A and the operation input section 11 in state ST11. FIG. 11B is a side view showing the display section 17A and the operation input section 11 in state ST12. FIG. 12(a) is a schematic diagram showing the lock mechanism section 17h in state ST11. FIG. 12(b) is a schematic diagram showing the lock mechanism section 17h in the stopped state in the state ST12. FIG. 12(c) is a schematic diagram showing the lock mechanism portion 17h in the rotating state in the state ST12.

In this modified example, the configuration of the ultrasonic diagnostic apparatus 100 of the above-described embodiment, in which the display unit 17 is replaced with a display unit 17A, is used. Therefore, the parts different from the ultrasonic diagnostic apparatus 100 of the embodiment will be mainly described.

As shown in FIGS. 11A and 11B, the display unit 17A of the ultrasonic diagnostic apparatus 100 of this modified example has a display body 171 and a support 172A. The support portion 172A has a support 17c1, a hinge 17d1, a support 17f1, and a lock mechanism portion 17h. The support 17c1, the hinge 17d1, and the support 17f1 are the same as the support 17c, the hinge 17d, and the support 17f of the above embodiment, respectively.

The lock mechanism 17h locks the pivot rotation of the display main body 171 when the tilt angle φ of the display main body 171 is less than a predetermined angle, and unlocks the pivot rotation of the display main body 171 when the tilt angle φ is equal to or greater than the predetermined angle. It is a lock mechanism unit that is set to a state. The locked state of the lock mechanism portion 17h in FIG. 11A is assumed to be state ST11, and the unlocked state of the lock mechanism portion 17h shown in FIG. 11B is assumed to be state ST12.

As shown in FIG. 12(a), the lock mechanism portion 17h has a rotating portion 17h1 and a projection portion 17h2. The rotating portion 17g has guide holes 17ha and 17hb, and is fixedly installed on the back surface of the display panel 17a so that it can pivotally rotate together with the display main body portion 171. be. The guide hole 17ha is a hole into which the protrusion 17h2 is fitted, for example, when the display main body 171 is in a vertical state (corresponding to state ST2 in FIG. 2). The guide hole 17hb is a hole into which the protrusion 17h2 is fitted, for example, when the display main body 171 is in a horizontal state (corresponding to state ST1 in FIG. 2). The protrusion 17h2 is a protrusion to be fitted into the guide holes 17ha and 17hb, and it is possible to maintain a state of being fitted into or removed from the guide holes 17ha and 17hb by biasing and releasing the elastic body. be.

As shown in FIG. 12(a), for example, when the display main body 171 is in a horizontal state, in a state ST11 corresponding to FIG. The pivot rotation of the rotating portion 17h1 (display body portion 171) is disabled. Then, as shown in FIG. 12(b), when the operator pulls out the projecting portion 17h2 from the guide hole 17ha to release the locked state to the unlocked state, the state ST12 corresponding to FIG. 11(b) is reached. .

As shown in FIG. 12(c), in the unlocked state of state ST12, the rotating portion 17h1 (display panel 17a) can be pivotally rotated. After being fitted, for example, the display main body 171 is placed in a sideways state to be in a locked state.

As described above, according to this modified example, similarly to the support portion 172 of the above-described embodiment, the support portion 172A includes the support body 17c1 that supports the display body portion 171 and the extension direction (z-axis direction) of the support body 17c1. and a hinge 17d1 as an adjustment unit that adjusts the tilt angle φ of the display main body 171 relative to the and a lock mechanism portion 17h that locks the impossible state and unlocks the pivot rotation of the display body portion 171 when the tilt angle φ is greater than or equal to the first angle. Therefore, with a simple configuration, the display main body 171 interferes with the operation input unit 11 or the like during the pivot rotation of the display main body 171 when the display main body 171 is tilted and the tilt angle φ is equal to or greater than the first angle. The position of the lower side of the display body portion 171 can be substantially the same before and after the pivot rotation.

Further, the lock mechanism 17h locks the display main body 171 when the rotation angle of the pivot rotation of the display main body 171 becomes a preset second angle (rotation angle corresponding to the positions of the guide holes 17ha and 17hb). to lock the pivot rotation of the . Therefore, when the rotation angle of the pivot rotation of the display main body 171 becomes the desired second angle, the pivot rotation of the display main body 171 can be reliably prevented.

(Second modification)
A second modification of the above embodiment will be described with reference to FIGS. 13 to 15(b). FIG. 13 is a diagram showing the rotation axis R4 of the display screen of the display body 171 of this modification. FIG. 14 is a diagram showing the rotation axis R5 of the display screen of the display body 171 of this modification. FIG. 15(a) is a front view showing the display body 171 and the operation input unit 11 before rotation in this modified example. FIG. 15(b) is a front view showing the display body 171 and the operation input unit 11 after rotation in this modified example.

In the above embodiment, before and after the pivot rotation of the display main body 171, the position of the lower side of the display main body 171 (the display screen of the display panel 17a) (the distance from the operation input unit 11) is constant. It was a configuration in which the shaft was arranged. In this modification, the horizontal or vertical position of the center point CP1 of the display main body 171 is constant before and after the display main body 171 pivots.

As an apparatus configuration of this modified example, the ultrasonic diagnostic apparatus 100 is used as in the above-described embodiment.

As shown in FIG. 13, the axis of pivot rotation of the display body 171 is set on the line L2 of the display screen of the display body 171 (display panel 17a). The rotation axis on line L2 is assumed to be rotation axis R4. Also, lengths W, H, A (A1), B, and length D are shown on the display screen of the display body 171 . A line with length D=W/2−A=H/2−B and −H/2≦D≦+H/2 is line L2. As shown in FIG. 13, the sides of the display screen of the display body 171 are sides e1, e2, and e3. The line L2 is a line of approximately the same length D on each of two adjacent sides (sides e2 and e3) from the center point CP1 of (the display screen of) the display body 171 . The line L2 passes through the center point CP1 and is a line of z=-y+(W+H)/2 when the common end point O of the sides e1 and e2 is the origin.

With the display main body 171 in the sideways state in FIG. The position in the lateral direction (y-axis direction) is constant before and after rotation. Further, when the display main body 171 is pivotally rotated +90° about the rotation axis R4 from the horizontal display main body 171 in FIG. becomes constant before and after rotation.

As shown in FIG. 14, on the display screen of the display body 171, the rotation axis of pivot rotation is arranged at the intersection of the lines L1 and L2, and this rotation axis is defined as the rotation axis R5. The rotating shaft R5 is arranged at a position where A=(H+W)/4. In this way, by pivoting the display main body 171 about the rotation axis R5, the position of the lower side of (the display screen of) the display main body 171 becomes constant before and after the rotation (effect corresponding to the line L1), and The horizontal or vertical position of the center point CP1 is constant (effect corresponding to line L2).

Furthermore, by moving the rotation axis R5 in the direction of the double-headed arrow DA1 extending in the direction perpendicular to the line L1 on the display screen of the display main body 171, the display main body 171 (the display screen thereof) is rotated before and after the pivot rotation. You can adjust the position (height) of the bottom edge. Further, by moving the rotation axis R5 in the direction of the double-headed arrow DA2 extending in the direction perpendicular to the line L2 on the display screen of the display main body 171, the display main body 171 (the display screen thereof) is rotated before and after the pivot rotation. The position of the center point CP1 can be adjusted.

Here, as the rotation axis for pivoting the display main body 171, the rotation axis R6 is defined by moving the rotation axis R5 along the line L2 by a predetermined short distance. FIG. 15A shows the display main unit 171 and the operation input unit 11 before the pivot rotation of the display main unit 171 about the rotation axis R6, and this position and display state is assumed to be the state ST13. . 15(b) shows the display main body 171 and the operation input unit 11 in a state where the display main body 171 has been pivotally rotated by -90° about the rotation axis R6 from the state ST13. is assumed to be state ST14.

In state ST13, screen 300 is displayed on display body 171 (display panel 17a). In the state ST14, the screen 310 is displayed on the display main unit 171. FIG. In the state ST<b>14 , the display unit 17 is configured such that the position of the lower side of (the display screen of) the display main unit 171 is substantially the same as the position of the upper side of the operation input unit 11 . On the other hand, in the state ST13, since the rotation axis R6 is off the line L1, the position of the lower side of the display screen of the display panel 17a is separated from the position of the upper side of the operation input section 11. FIG. 15(a) and 15(b), between the vertical position (z-axis direction) of the ultrasonic image 301 and the vertical position of the operation input unit 11 in each of the states ST13 and ST14. is indicated by a double-headed arrow. The position of the ultrasonic image 301 in the vertical direction is set above the central position in the vertical direction of the ultrasonic image 301 because most of the important information of the ultrasonic image 301 is on the body surface (upper side) side. Further, the vertical position of the operation input unit 11 is the center position of the operation input unit 11 in the vertical direction.

15(a) and 15(b), the vertical position of the ultrasonic image 301 from the operation input unit 11 in state ST13 and the ultrasonic image from the operation input unit 11 in state ST14. The difference from the vertical position of the sound wave image 301 is smaller than in the states ST5 and ST6 of FIGS. 7B and 7A. Therefore, before and after the pivot rotation, the operator can easily observe the ultrasonic image 301 without significantly moving the line of sight in the vertical direction.

Further, since the rotation axis R6 is on the line L2, the horizontal direction of (the display screen of) the display body 171 in the state ST13 is based on the center position of the fixed operation input unit 11 in the horizontal direction (y-axis direction). and the horizontal center (center point CP1) position of (the display screen of) display body 171 in state ST14 are substantially the same.

As described above, according to this modified example, the rotation axes R5 and R6 are substantially the same on each of two adjacent sides (sides e2 and e3) from the center point CP1 of (the display screen of) the display body 171. It is arranged at the position of length D as the fourth length (position on line L2). Therefore, the position of the center point CP1 in the horizontal direction (y-axis direction) or the vertical direction (z-axis direction) can be substantially the same before and after the display body 171 pivots.

Also, the length A as the third length is (length W as the first length+length H as the second length)/4 (rotational axis R5). For this reason, for example, when the rotation angles of the pivot rotation are 0°, −90°, and +90°, before and after the pivot rotation of the display body 171, the lower side of the display body 171 (in the z-axis direction) The positions can be substantially the same, and in two states of rotation angles of 0° and -90°, the position of the center point CP1 in the lateral direction (y-axis direction) can be substantially the same, and the rotation angles are 0° and +90°. 2, the position of the center point CP1 in the vertical direction (z-axis direction) can be substantially the same.

In the above description, an example of using a ROM as a computer-readable medium for the program according to the present invention has been disclosed, but the present invention is not limited to this example. As other computer-readable media, it is possible to apply non-volatile memory such as flash memory and portable recording media such as CD-ROM.
