It is to be noted that a circuit that detects a change in electrostatic capacitance is provided at an appropriate position of, for example, the sensor board 39 . the

As shown in FIGS. 9A , 9B, 10A, and 10B , the key sheet 41 is arranged to cover most of the outer circumferential side of the annular region 39 c of the sensor board 39 . That is, the outer edge of the key sheet 41 is located on the outer peripheral side with respect to the case opening 23h of the rear case 23, and the inner edge of the key sheet 41 is located on the outer peripheral side of the plate opening 39h and relative to the key switch 45 and the touch sensor electrodes. 47 is located on the inner peripheral side. the

A clamping portion 41 c sandwiched between the bottom of the sheet recess 23 b of the rear case 23 and the decorative panel 25 is formed on the outer edge side of the key sheet 41 . The clamping portion 41c is clamped across the outer circumferences of the case opening 23h and the panel opening 25h. In other words, the clamping portion 41c is formed in an annular state to surround the case opening 23h and the panel opening 25h. The clamping portion 41c is formed thickly so as to protrude to the decorative panel 25 side. The thickness of the clamping portion 41c is, for example, 0.2 mm. It is to be noted that, in the drawings, the clamping portion 41 c is separated from the decorative panel 25 , but actually, the clamping portion 41 c is in close contact with the decorative panel 25 . the

An abutment portion 41d is formed on the inner edge side of the key sheet 41, the abutment portion adjoining the mounting of the sensor board 39 at a position on the outer peripheral side of the board opening 39h and on the inner peripheral side relative to the key switch 45 and the touch sensor electrode 47. Surface 39a. The abutment portion 41d is formed thick to protrude to the sensor board 39 side. The abutment portion 41d is formed in an annular shape to surround the plate opening 39h. The abutment portion 41d is formed in a region superimposed on the ring key 7 . the

The cover portion 41 e between the clamping portion 41 c and the adjacent portion 41 d covers the key switch 45 , the touch sensor electrode 47 and the light emitting element 53 . The cover portion 41 e is separated from the mounting surface 39 a of the sensor board 39 by the function of the rear case 23 between the abutment portion 41 d and the clamping portion 41 c and the sensor board 39 as a spacer. the

As shown in FIGS. 9A and 9B , in the cover portion 41 e , a squeezer 41 b for helping to depress the key switch 45 is formed at a position facing each key switch 45 . The squeezer 41b is formed thickly by protruding toward the key switch 45 side. It is to be noted that, as shown in FIG. 10A , the squeezer 41 b is not formed at the position where the touch sensor electrode 47 is arranged. the

As shown in FIGS. 9A, 9B, 10A and 10B, the ring key 7 has an exposed surface 7a exposed from a panel opening 25h. As shown in FIGS. 6 , 9A, 10A, and 10B, the exposed surface 7 a has an upper surface 7 b on the outer circumference side and an inclined surface 7 c on the inner circumference side. It is to be noted that, in FIG. 9B , the upper surface 7 b and the inclined surface 7 c are not shown due to grooves provided in the exposed surface 7 a and extending in the radial direction. the

As shown in FIGS. 9A , 9B, 10A, and 10B, the upper surface 7 b is located on the outer side of the housing (upper side of the paper surface) with respect to the exposed surface 35 a of the tab 35 . The upper surface 7b is formed substantially parallel to the rear surface 2b of the first housing 2, the trim piece 35, the sensor board 39, and the like. As shown in FIG. 9A and FIG. 9B, the outer edge of the upper surface 7b (the outer edge of the exposed surface 35a), in other words, the position where the impact (stroke) of the upper surface 7b is the largest, is located between the squeezer 41b and the key switch. 45 at the center. the

As shown in FIGS. 9A , 9B, 10A, and 10B, the inclined surface 7c is located on the outer side of the housing (upper side of the paper surface) with respect to the exposed surface 35a of the adjustment plate 35 . The inclined surface 7c is inclined such that the inner circumferential side is located on the inner side of the case. As shown in FIG. 9A , the inclined surface 7 c is located on the inner circumference side with respect to the key switch 45 so that force applied to the inclined surface 7 c in a direction perpendicular to the inclined surface 7 c becomes easily transmitted to the key switch 45 side. Note that the inclined surface 7c can be controlled as a slope provided in a ridge formed by the upper surface 7b serving as an exposed surface from the panel opening 25h and the inner peripheral surface of the ring key 7 . the

As shown in FIGS. 9A and 9B, a radially protruding flange 7f is formed on the outer circumferential side of the ring key 7 (see also FIG. 12). The flange 7f is engaged with the edge portion of the panel opening 25h of the decorative panel 25 from the inner side of the panel, and serves as a stopper that prevents the ring key 7 from being separated from the panel opening 25h. The flanges 7f are arranged at four positions in the same manner as the arrangement positions of the squeezers 41b (key switches 45) (see FIG. 12). The squeezer 41b is located at a position superimposed on the flange 7f. the

As shown in FIGS. 9A, 9B, 10A and 10B, the surface of the ring key 7 on the inner side of the housing has a fixing surface 7d on the outer circumference side and a facing surface 7e on the inner circumference side. The cover portion 41 e that fixes the fixing surface 7 d to the key sheet 41 by adhesive, double-sided tape, or other fixing means fixes the ring key 7 with respect to the key sheet 41 . the

The facing surface 7 e faces the abutting portion 41 d of the key sheet 41 . The facing surface 7e is positioned in a direction farther away from the key sheet 41 (upper side of the paper surface) than the fixing surface 7d. That is, a step is formed on the surface of the ring key 7 facing the key sheet 41 such that the inner peripheral side is further apart from the key sheet 41 than the outer peripheral side. In addition, the facing surface 7e is separated from the key sheet 41 by a predetermined gap, so it is prevented from becoming difficult to depress the ring key 7 by the abutment portion 41d. the

The facing surface 7e faces a part of the adjustment plate 35 on the outer circumference side of the exposed surface 35a. In other words, the ring key 7 has a ring-shaped overlapping portion 7 g covering the outer peripheral portion of the exposed surface 35 a of the adjustment plate 35 . When the ring key 7 is depressed, the facing surface 7e abuts the exposed surface 35a of the adjustment plate 35 . Thereby, it is possible to prevent an excessive load from being applied to the key switch 45, the touch sensor electrode 47, and the light emitting element 53 by the ring key 7 when depressed. the

The exposed surface 35a of the adjustment plate 35 has an upper surface 35b occupying most of the exposed surface 35a and an inclined surface 35c on the outer circumferential side of the upper surface 35b. The upper surface 35b is formed in a planar state parallel to the decorative panel 25, the sensor board 39, and the like. The inclined surface 35c is inclined such that the outer circumferential side is located on the inner side of the housing. Note that the inclined surface 35c may be controlled as a slope provided in a ridge formed by the upper surface 35b serving as an exposed surface from the panel opening 25h and the inner peripheral surface of the adjustment plate 35 . When the ring key 7 is depressed, the facing surface 7e abuts against the inclined surface 35c. the

As shown in FIG. 10B , the reinforcing frame 31 has an engagement portion 31 c (see also FIG. 4 ) protruding from the rib 31 b toward the side surface 21 c along the side surface 21 c of the front case 21 . On the other hand, an engaged portion 21d engageable with the engaging portion 31c is formed on the inner surface of the side surface 21c. The engaged portion 21d is formed by the formation of a recess in which the protruding portion of the engaging portion 31c is accommodated on the inner surface of the side surface 21c. the

The frame assembly 51 is fixed relative to the front case 21 by the engagement of the engaging portion 31c and the engaged portion 21d. At this time, the dustproof sheet 43 adjoins the periphery of the display surface 29 a of the sub display device 29 . That is, the sub display device 29 is sandwiched between the reinforcement frame 31 and the front case 21 by the engagement of the engagement portion 31 c and the engaged portion 21 d and the fixation of the reinforcement frame 31 relative to the front case 21 . the

11 is a view illustrating a waterproof structure on the inner circumference side of the ring key 7, in which FIG. 11A is an enlarged view of the periphery of the ring key 7, and FIG. 11B is a view basically showing the region XIb of FIG. 11A. the

The housing outer limit position (upper limit position with respect to the upper side of the paper surface) of the cover portion 41 e of the key sheet 41 is defined by the fixing surface 7 d of the ring key 7 . The outer limit position of the housing of the ring key 7 (upper limit position with respect to the upper side of the paper surface) is defined by the flange 7f. the

As shown in FIG. 11A , the key sheet 41 is formed such that the inner circumference side portion is bent to the sensor board 39 side in the case where the key sheet 41 is not connected to the first housing 2 . Specifically, on the cover portion 41e, a bent portion 41f is formed such that the abutting portion 41d is located on the sensor board 39 side. The bent portion 41 f is provided, for example, near the boundary between the fixing surface 7 d and the facing surface 7 e of the ring key 7 . the

By providing the bent portion 41f, the amount by which the abutting portion 41d protrudes from the fixing portion of the covering portion 41e becomes larger than the distance DS1 between the upper limit position of the fixing portion and the mounting surface 39a of the sensor board 39 to which the fixing surface 7d is fixed. the fixed part. the

Therefore, as shown by the dotted line in FIG. 11B , the cover portion 41 e that has been bent before being connected to the first housing 2 (as shown by the solid line in FIG. 11B ) corrects the bending when being connected to the first housing 2. Elastic deformation in the direction and generate a restoring force. The abutment portion 41d is pressed against the sensor plate 39 by using the restoring force as a biasing force. the

Note that the amount by which the abutment portion 41d protrudes from the cover portion 41e and the thickness of a portion sandwiched between the clamp portion 41c and the sensor board 39 inside the rear case 23 are set equal to the distance DS1. Therefore, when the key sheet 41 is attached to the first housing 2, the covering portion 41e becomes substantially planar. the

As shown in FIGS. 4 and 10A , the plate-like portion 31 a of the reinforcement frame 31 is provided with a recess 31 d at a position overlapping with the touch sensor electrode 47 . The concave portion 31 d is selectively provided corresponding to a portion of the plurality of touch sensor electrodes 47 in which electronic components are arranged close to the portion of the touch sensor electrodes 47 . FIG. 4 shows a case where the concave portion 31d is formed corresponding to the touch sensor electrode 47 on the right side of the paper surface and the touch sensor electrode 47 on the left side of the paper surface. It should be noted that the concave portion 31d can also be provided corresponding to all the touch sensor electrodes 47. the

Each recess 31 d is formed by providing a hollow in the surface of the plate-like portion 31 a of the reinforcement frame 31 on which the sensor board 39 is placed. The inside of the recessed portion 31d forms a cavity in which air exists. It is to be noted that the dielectric constant (for example, 2.0-6.0) of the resin forming the reinforcing frame 31 is larger than that of air (about 1.0). Therefore, in the reinforcement frame 31, the region superimposed on the touch sensor electrode 47 has a lower dielectric constant than other regions, so it is difficult to change the capacitance at the reinforcement frame 31 on the side opposite to the touch sensor electrode 47, thereby This causes the capacitance on the touch sensor electrode 47 side to change. the

Electronic components are arranged at positions on the display panel 27 that overlap with the recessed portion 31d. Electronic components include metal components and other components that have relatively high dielectric constants. In FIG. 4, it is illustrated that the connector 67 (see also FIG. 3) is provided on the right side of the paper surface at a position superimposed on the recess 31d and the IC 69 is provided on the left side of the paper surface at a position superimposed on the recess 31d. situation at the location. In FIG. 10A , a connector 67 is illustrated as an electronic component. The connector 67 is a connector for electrically connecting the display panel 27 and an unillustrated circuit board of the second housing 3 . Unillustrated signal lines extending from the circuit board of the second housing 3 are connected to the connector 67 . the

As shown in FIG. 10A, the connector 67 is provided at a position facing the case opening 2h (the case opening 23h and/or the panel opening 25h). Furthermore, the connector 67 is covered by the supporting member 71 . The supporting member 71 is a member having a dielectric constant lower than that of the reinforcement frame 31 and the connector 67 . The thickness of the portion sandwiched between the connector 67 and the reinforcement frame 31 within the support member 71 is equal to the distance between the connector 67 and the reinforcement frame 31 in the case where no weight is exerted on the reinforcement frame 31 . Therefore, even when the sensor board 39 and the reinforcing frame 31 are bent toward the display panel 27 side by pressing the ring key 7, the support member 71 functions as a spacer, so the distance between the touch sensor electrodes 47 and the connector 67 remains constant. . It is to be noted that the support member 71 may also be supported on the display panel 27 without the connector 67 . the

12 is a view illustrating a method of illuminating the ring key 7 through the light emitting element 53, wherein FIG. 12A is a plan view of the ring key 7 and the key sheet 41, and FIG. 12B is a view in a state where the ring key 7 is exposed from the panel opening 25h Magnification of region XIIb of 12A. the

Each light emitting element 53 is constituted by, for example, an LED. As shown in FIG. 10A , the light emitting element 53 is arranged at a position overlapping with the ring key 7 . The ring key 7 and the decorative panel 25 are formed of a material having no light-transmitting property, and/or are coated with a paint having no light-transmitting property. The key sheet 41 is formed of a light-transmitting material. Light from the light emitting element 53 is guided to the outside of the first housing 2 through the key sheet 41 from the gap 65 between the outer edge 7k of the ring key 7 and the panel opening 25h. the

As shown in FIG. 12B, the gap 65 is formed to become narrower as the gap approaches the flange 7f. For example, the outer edge 7k of the ring key 7 (the inner edge of the gap 65) is a perfect circle in the area other than the area where the flange 7f is provided. However, in contrast to this, as shown in FIG. 12A, the shape of the panel opening 25h (the outer edge of the gap 65) is not a perfect circle, but is set so that the diameter becomes smaller and smaller as approaching the flange 7f. It is to be noted that the gap 65 can also be kept at a constant width at a position separated to some extent from the flange 7f. the

FIG. 13 is a block diagram showing an example of the structure of the signal processing system of the mobile phone 1 . the

The mobile phone 1 is provided with a control unit 101 , a communication processing unit 104 , an audio processing unit 106 , and an image processing unit 103 . the

The control unit 101 receives input signals from the operation unit 111 and various other devices, performs predetermined processing based on these signals, and will be used to control the operations of the image processing unit 103, communication processing unit 104, audio processing unit 106, and various other devices The control signal and various other signals are output to various devices. the

The communication processing unit 104 includes a high-frequency wave circuit, and performs wireless communication using electric waves by modulating audio data, image data, and other various types of data processed at the control unit 101 and transmitting the result through the antenna 105 . Furthermore, the communication processing unit 104 demodulates the signal received through the antenna 105 and outputs the result to the control unit 101 . the

The audio processing unit 106 converts the audio data from the control unit 101 into an audio signal, and outputs the signal to the speaking speaker 107 and the broadcast and music playback speaker 109 (see also FIG. 4 ). The audio processing unit 106 converts the audio signal from the loudspeaker 108 into audio data and outputs the data to the control unit 101 . the

The image processing unit 103 converts the image data from the control unit 101 into an image signal, and outputs the signal to the main display device 49 and the sub display device 29 . Furthermore, the image processing unit 103 converts the capture signal (image data) output from the camera 9 into image data having a predetermined format, and outputs the result to the control unit 101 . the

The operation unit 111 includes key switches 45 and touch sensor electrodes 47 . Each key switch 45 outputs an ON signal by causing the movable contact 45a to abut the fixed contact 45c when depressed by the ring key 7 as described above. Each of the touch sensors 48 including the touch sensor electrodes 47 outputs a signal according to a change in electrostatic capacity due to the user's finger approaching or touching the ring key 7 as described above. It is to be noted that this signal may be an output as an ON signal when the electrostatic capacitance exceeds a predetermined threshold, or may be a signal having continuous or step levels proportional to the magnitude of the electrostatic capacitance. the

A plurality of key switches 45 and touch sensor electrodes 47 are arranged on a circumference along the ring key 7 , so the control unit 101 can recognize the position of the user's finger on the ring key 7 according to signals from the key switches 45 and touch sensor electrodes 47 . the

For example, when an ON signal is output from any one of key switches 45 arranged in four (for example, up, down, left, and right) directions, a position in one of the four directions is recognized was depressed. When an ON signal is output from two adjacent key switches 45 arranged in four (for example, up, down, left, and right) directions, four directions (inclined directions) between the aforementioned four directions are recognized. ) in one direction is depressed. the

Likewise, when an ON signal is output from any one of the touch sensor electrodes 47 arranged in four (for example, up, down, left, and right) directions, it is recognized that the user's finger touch position in one direction. When the ON signal is output from adjacent two touch sensor electrodes 47 arranged in four (for example, up, down, left, and right) directions, it is recognized that the user's finger touches four of the aforementioned four directions. The position in one of the directions (slant directions). the

The control unit 101 can also recognize changes in the position of the user's finger over time by recording the recognized historical positions of the user's finger. For example, a rotation operation in which the user slides his finger along the ring key 7 to continuously move the finger, ie, an operation of tracing the outline of the ring key 7 , can be recognized. Due to this, according to the amount of time or angle for which the finger continuously moves around the ring key 7, for example, the output volume from the speaker 109 may be increased or decreased, the brightness of the sub display device 29 may be increased/decreased, or may be within a predetermined period. The display content of the sub display device 29 is changed. the

It should be noted that the control unit 101 processes the signals from the touch sensor electrodes 47 and the key switch 45 to distinguish between a simple touch operation and a depress operation (including touch, of course) where the finger only touches the ring key 7 without depressing the key. the

That is, when the ON signal is only output from the touch sensor electrode 47, but no ON signal is output from the key switch 45, the control unit 101 judges that the operation is a simple touch operation, and when the ON signal is output from the key switch 45 (and touch When the sensor electrode 47) is output, the control unit 101 judges that the operation is a pressing operation, so the control unit 101 can realize control signals corresponding to two different operations. the

According to the above embodiments, it is possible to provide an electronic device that gives a sense of unity to the display and the operating member. the

In addition, the key switch 45 is provided at a position superimposed on the ring key 7, and thus has a "click" feeling compared to the case where the touch panel is provided on the sub display device 29, and thus is easy to operate. The reinforcement frame 31 not only supports the adjustment board 35, but also supports the sensor board 39, on which the force pressed on the key switch 45 is applied, and the reinforcement frame is generally used to strengthen the strength of the sensor board 39, thus realizing Reduction in size of the mobile phone 1 . The reinforcement frame 31 has a relatively wide area covering the display panel 27 , so it generally also serves to reinforce the strength of the display panel 27 . the

The sub-display device 29 is sandwiched between the surface of the first case 2 opposite to the surface provided with the case opening 2h (inner side surface of the front case 21) and the reinforcement frame 31, so the reinforcement frame 31 is generally used to hold and reinforce the sub-display device 29, and a reduction in the size of the mobile phone 1 is achieved. In addition, by enabling the reinforcement frame 31 to be fixed to the front case 21 through the engaging portion 31c and the engaged portion 21d provided on the front case 21, the sub display device 29 and the reinforcement frame 31 can be combined with the front case 21 and the rear case. The body 23 is previously fixed to the front housing 21, thus facilitating the assembly process. The dust-proof sheet 43 made of an elastic member is provided between the display surface 29a of the sub-display device 29 and the reinforcement frame 31, so that the sub-display device 29 can be securely clamped with a predetermined pressing force without scratching the sub-display device 29. display device 29, and prevent water and dust from entering the display surface 29a. the

The device also has a touch sensor electrode 47 provided on the mounting surface 39 a of the sensor board 39 facing the housing opening 2 h and arranged at a position overlapping the ring key 7 .

The device is also provided with a light emitting element 53 provided on the mounting surface 39a of the sensor board 39 facing the housing opening 2h and capable of transmitting light from the light emitting element 53 to the gap outside the first housing 2 65 is formed between the ring key 7 and the housing opening 2h, so that the inner edge of the ring key 7 can be visually confirmed by the light from the sub-display 5, and the outer edge of the ring key 7 can be visually confirmed by the light from the light emitting element 53. Visually confirmed. Therefore, operability at night can be improved while suppressing an increase in the number of parts. the

The light emitting element 53 is arranged at a position superimposed on the ring key 7, thus effectively utilizing the area in the mounting surface 39a of the sensor board 39 superimposed on the ring key 7, and the mobile phone 1 can be downsized. the

The ring key 7 has a plurality of flanges 7f as stoppers that can be engaged with the edge of the housing opening 2h in the first housing 2 from the inside of the housing. The gap 65 between the ring key 7 and the housing opening 2h is formed to become narrower as the gap approaches the plurality of flanges 7f, so the light from the light emitting element 53 will gradually decrease as it approaches the flanges 7f. , so the portion blocked by the flange 7f is not presented. the

Furthermore, according to the above embodiments, an electronic device having a high degree of freedom in design and high waterproof or dustproof characteristics can be provided. the

That is, the device has: a third housing 2' composed of a rear housing 23 having a housing opening 23h and a front housing 21; a decorative panel 25 having a panel opening 25h and placed On the third casing 2' such that the panel opening 25h overlaps with the case opening 23h; the reinforcement frame 31, which is provided in the third casing 2'; the adjustment plate 35, which is fixed to the reinforcement frame 31 The surface facing the casing opening 2h, and arranged in the casing opening 23h and the panel opening 25h; the sensor plate 39, which is arranged on the surface of the reinforcement frame 31 facing the casing opening 23h, and has an insertion the panel opening 39h of the adjustment plate 35; the touch sensor electrode 47 provided on the mounting surface 39a of the sensor board 39 facing the case opening 23h; the key sheet 41 provided on the sensor board 39 on the surface facing the housing opening 23h to cover the touch sensor electrodes 47, and the key sheet has a sheet opening 41h that has a smaller diameter than the housing opening 23h and panel opening 25h , the adjustment plate 35 is inserted into the sheet opening; and the ring-shaped ring key 7 is provided at a position overlapping with the touch sensor electrode 47 on the surface of the key sheet 41 facing the housing opening 23h , and exposed from the gap between the panel opening 25h and the housing opening 23h and the adjustment plate 35, wherein the key sheet 41 has an annular clamping portion 41c and an annular abutting portion 41d, the clamping portion is held by the third housing 2' and the decorative panel 25, and surround the case opening 23h and the panel opening 25h, the abutting portion adjoins the mounting of the sensor plate 39 facing the case opening 23h at a position on the inner circumferential side relative to the touch sensor electrode 47. Surface 39a to surround plate opening 39h. Therefore, at two positions between the key sheet 41 and the decorative panel 25 and between the key sheet 41 and the rear case 23, water and dust are prevented from passing between the panel opening 25h and the outer edge of the ring key 7 by the clamping portion 41c. The gap between the key sheet 41 and the sensor plate 39 prevents water and dust from entering through the gap between the adjustment plate 35 and the inner edge of the ring key 7 at the same time. That is, water and dust entering through the inner and outer edges of the ring key 7 are blocked by the key sheet 41 and cannot enter the inside of the third housing 2'.
