DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input device for a computer device. For example, car navigation
It belongs to a switch device of information equipment that requires simple ergonomic operability such as a display device mounted on a car including a car, and uses a single operation element to scroll the screen, select a menu, determine, etc. It can be used as a multi-function switch device having multi-functionality that enables the above. In particular, the present invention relates to a multi-function switch device capable of switching a display to a screen of a previous hierarchy by pulling an operation element.

[0002]

2. Description of the Related Art In recent years, a display device including a car navigation system has been provided in a vehicle cabin, thereby increasing convenience. However, the switches on the front panel of the driver's seat already have switches for other devices, and their operation is becoming more complicated and complicated. In order to reduce the complexity, in the car navigation system, a selection switch such as a menu is displayed on the liquid crystal panel, and the operator is allowed to select a determinant (cursor) according to an option and select the menu. I have. However, the change / decision of the option or the change / movement of the screen is input by a plurality of push-button switches arranged as images. For this reason, it is difficult for the operator to instantly grasp the function and the positional relationship between the switches, and a simple input method based on ergonomics is required.

Conventionally, various devices have been devised to simplify such complicated operations. For example, a single rotary switch with a push button switch can
There is known an apparatus in which the selection function and the determination function are performed at the same time, and the screen movement function is realized by combining another selection switch with the above-mentioned rotation switch, and the number of switches is reduced. As another example, there is also known a switch that uses an 8-directional discriminating switch having a push button switch for changing / determining options and moving a screen, instead of the rotary switch.

[0004]

However, in both cases, to return the screen on the display to the screen of the previous hierarchy,
An operation of selecting and determining a switch for returning to the previous hierarchy on the screen is required, which is complicated. In particular, an operation to return to the screen of the previous hierarchy can always occur in an arbitrary screen state, and performing such an operation every time it is necessary is not convenient. Particularly, it is more difficult to perform such an operation while driving a car. Also, when it comes to screen scrolling,
In the former case, it is necessary to select a menu for vertical scrolling and horizontal scrolling with a rotary switch and then determine the menu by pressing the switch, and to perform vertical scrolling or horizontal scrolling with the rotary switch. As described above, the scroll operation is difficult, and in particular, since the diagonal scroll in the 45-degree direction cannot be performed, the screen is temporarily scrolled to the left and right, and then the screen is scrolled up and down to the predetermined position. A two-stage operation of positioning was required. Such an operation was extremely difficult during operation. In the latter case using the eight-direction discriminating switch, the screen can be scrolled by one operation, so that the operability is improved, but the menus arranged in a matrix are arranged.
Is selected by this switch, an adjacent option may be selected by a slight erroneous operation, and there is a problem that it is difficult to operate.

[0005] The present invention has been made to solve the above-mentioned problems, and has as its object to facilitate screen operations on a display. Another object is to improve the operability of the screen operation by making it possible to easily return to the previous hierarchical screen by applying a pulling operation to a common operation element for instructing another screen operation. Still another object is to facilitate screen scrolling by further applying a tilt operation in the radial direction about the axis to the common operation element. Still another object of the present invention is to improve operability by making it possible to perform basic operations with one common operation element in an input method to a display device including car navigation of a car.

Therefore, regardless of the screen state on the display, it is possible to immediately return to the previous hierarchical screen by one simple operation of pulling the operation element, so that the operability is extremely high. Further, in addition to the rotation operation for specifying the option and the pressing operation for determining the option, the third operation called the pulling operation is added to the common operation element, so that the screen operation can be executed by one operation element. Operability is improved. Further, since many functions can be commanded by one operation element, the device can be downsized. When this multi-function switch device is applied to a display device including a car navigation device, operations such as setting a destination, selecting a hierarchically structured map, and switching to a display other than navigation are extremely simple. Thus, the load on the driving operation can be reduced.

In particular, when applied to an in-vehicle display device including a navigation device, the load on the driver is reduced, which is particularly effective.

According to a third aspect of the present invention, the tension detecting means is configured to detect the displacement or stress of the operating element in the axial direction by a change in voltage or current. The tension detecting means is constituted by means for converting the displacement of the operating element into an electric signal according to the displacement. Thus, the displacement or stress in the axial direction of the operating element can be detected as an electric signal.

According to a sixth aspect of the present invention, since the tension detecting means is a piezoelectric element for converting the stress acting on the operating element in the axial direction into an electric signal, there is no movable part, and there are few failures and power saving. .

It consists of 60. The above units are all system bus 15
0, and data is exchanged in both directions.

The in-vehicle display device is shown in FIG. 14, in which an operation element 100 is arranged beside the display 160. In this embodiment, the operation element 100 can be rotated, pressed, and pulled. FIG. 14 (a)
As shown in the figure, the designated position of the option on the menu screen is changed by the rotation of the operating element 100, the selection of the option of the designated position at that time is determined by the pressing operation of the operating element 100, and the previous operation is performed by the pulling operation of the operating element 100. The screen can be switched to a hierarchical screen.

FIG. 2A shows the configuration of the operation element 100. At one end of the shaft 20, a pressure-sensitive element 15 is provided as a pressing detection means for detecting a pressing operation, and an operation plate 10 is provided on the surface of the pressure-sensitive element 15. The shaft 20 is axially slidably and rotatably supported by a bearing 80 made of an insulator. Contact terminals 30 and 31 are provided on an end face 80 a of the bearing 80. A switch plate 40 is provided at the other end of the shaft 20, and the switch plate 40 is moved by the movement of the shaft 20 in the direction B by the pulling operation.
Contact the contact terminals 30 and 31. The tension detecting means includes a switch plate 40 and contact terminals 30 and 31. A coil spring 70 for urging the shaft 80 in the F direction between the end surface 80a of the bearing 80 and the switch plate 40.
Are arranged. A convex contact 41 is formed in the vicinity of the outer peripheral portion of the surface of the switch plate 40, and the contact 41 and the resistance plate 60 are in contact with each other when no tensile force is applied to the shaft 20 in the B direction. . As shown in FIG. 2 (b), the resistance plate 60 has a resistance wire disposed on the circumference thereof.
The resistance is divided by the contact position of No. 1 and a divided voltage is detected. The voltage of the contact 41 is output to the outside by a contact terminal 50 that contacts the peripheral surface of the switch plate 40. The rotation direction detecting means includes a switch plate 40, a contact 41, and a resistance plate 60.
It is composed of

The arrow in the figure indicates the operating direction. In a normal state, the resistance plate 60 and the contact point 41 are in contact with each other by the coil spring 70. When the operation plate 10 is pressed in the F direction, the shaft 20 does not move, and a pressing stress is applied to the pressure-sensitive element 15. Due to this pressing stress, the resistance of the pressure-sensitive element 15 decreases, and the signal Sd1 corresponding to the pressing force is reduced.
(Voltage V) is output to the outside. When the operation plate 10 is pulled in the direction B, the switch plate 40 comes into contact with the contact terminals 30 and 31, and the contact terminals 30 and 31 become conductive, so that the signal Vd of the voltage V is output. When the operation plate 10 is rotated in the R or L direction with the resistance plate 60 and the contact 41 in contact with each other, the position of the contact 41 on the resistance plate 60 changes. The operating plate 10, and thus the R direction or L of the shaft 20
Due to the rotation in the direction, a divided voltage signal Sa, which is an analog signal corresponding to the rotation angle, is output to the outside via the contact terminal 50.

Next, a processing procedure in which the screen data of the previous hierarchy is displayed on the display 160 by the pulling operation of the operating element 100 will be described with reference to the flowchart shown in FIG. When the power is turned on to the in-vehicle display device, the process is executed from step S100. Step S10
0, the navigation, as shown in FIG.
A use menu of a display such as a TV is displayed. When the operation plate 10 is rotated in this state, the position of the cursor P on the menu screen in FIG. 14A changes according to the changing signal Sa. The process of changing the position of the cursor P on the menu screen according to the signal Sa is performed by real-time parallel processing by another program. Next, in step S105, it is determined whether or not there is a pressing operation of the operation plate 10 based on the voltage level of the signal Sd1 from the pressure-sensitive element 15. This pressing operation is performed with the cursor P
, The pressure-sensitive element 15 will be referred to as a determination key, and a pressing operation will be referred to as an operation of the determination key. Thus, in step S105, the process waits until the enter key is pressed. When the enter key is pressed, the signal Sd1 goes high, and this level is set to Sd1 = 1. When the enter key is pressed, the process moves to the next step S110. Step S
110, the program N0. (N-1) is executed. For example, if the navigation menu is selected and determined, a program for displaying an initial screen for navigation is executed. Next, the signals Sd1 and Sd2 are detected in steps S120 and S130, and it is determined whether or not there is a pressing operation or a pulling operation of the operation plate 10, and the apparatus enters a standby state until an operation is performed.

In this standby state, when the enter key is pressed (Sd1 = 1), that is, a certain menu is selected,
Since it means that it has been determined, step S140
, The next level program is executed. For example, a menu for setting a destination is selected and set, and an initial screen for selecting a destination is displayed on the display 160. Next, in steps S150 and S160, as in steps S120 and S130, the signals Sd1 and Sd
2 is detected, and it is determined whether or not the operation of the operation plate 10 has been performed, and the apparatus enters a standby state until the operation is performed.

Hereinafter, the screen of the lower hierarchy is sequentially displayed by repeating the selection of the menu. On the other hand, in a state of a certain screen display, when a pulling operation of the operation plate 10 in the direction B is performed, the contact terminals 3
0 and 31 are conducted by the switch plate 40, and the signal Sd2
Is a high level indicating that a tensile operation has been performed (Sd2 = 1)
Becomes Hereinafter, the switch plate 40 is referred to as a return key, and the pulling operation of the operation plate 10 is referred to as a pulling operation of the return key.
For example, when the program of the n-th hierarchy is executed and the screen of the n-th hierarchy is displayed on the display 160, when the pull operation of the return key is executed, in step 150,
Sd2 = 1 is detected, and the process returns to step S110. In this way, the program N0. (N-
1) is executed. Thereby, the screen of the display 160 also becomes the screen of the immediately preceding hierarchy. For example, the destination setting menu changes to an initial navigation menu. In this way, the screen data being executed is instantaneously changed to the screen data of the previous hierarchy, and the key input such as menu selection, determination, return, etc. becomes possible again. Further, when the return key is pulled in this state, the display jumps to a further higher hierarchy and the first menu screen is displayed. As described above, in the present embodiment, it is possible to instantaneously return to the screen of the immediately preceding layer by any operation of pulling the operation plate 10, and the operability of the in-vehicle display device is extremely high. improves. The screen switching means is constituted by each step of FIG.

In the first embodiment (FIG. 2), the displacement of the switch plate 40 due to the pulling operation is detected by the conduction of the contact terminals 30 and 31. In this embodiment, a variable resistor 400 slidingly contacting the switch plate 40 is used instead, and the contact position is output as an analog signal Sb based on a resistance value that changes according to the displacement of the switch plate 40. The analog signal Sb is compared with a predetermined voltage by a comparator circuit, which is provided in the I / O interface 140 and takes into account a noise margin (not shown). = 1
Is output. That is, in the first embodiment, there is a possibility that the program may return two levels before due to noise such as chattering at the time of contact with the contact terminals 30 and 31, but in this embodiment, there is no chattering due to contact at the same time. Since sufficient noise margin can be obtained, no malfunction occurs during traveling.

(Third Embodiment) FIG. 5 shows the structure of an operation element of a device according to a third embodiment of the present invention. In the drawing, the same components as those in FIG. 2 are denoted by the same reference numerals.

When a stress is applied to the piezoelectric element 500 by 0, a voltage corresponding to the stress is generated in the piezoelectric element 500, and an analog signal Sc is obtained. The analog signal Sc is compared with a predetermined voltage by a comparator circuit provided in the I / O interface 140 in consideration of a noise margin, not shown, as in the second embodiment. , Sd2 = 1 is output. That is, the pulling operation of the operation plate 10 is detected. In this embodiment, as in the second embodiment, there is no chattering due to contact and at the same time, a sufficient noise margin can be obtained, so that there is no malfunction during traveling. In addition, since the power used for detection is given by the stress accompanying the operation, power saving can be achieved.

If installed, there is a possibility that electromagnetic wave noise that cannot be avoided by the above-mentioned comparator will be superimposed on the wiring 141 (FIG. 1).

In the present embodiment, a bidirectional optical fiber 600 disposed inside the bearing 80 as shown in the figure is used instead of the wiring 141. The optical transceiver 610 is
The light transmitted from the I / O interface 140 passes through the fiber 600 and passes through the switch plate 4.
Reflected at 0. The light reflected by the switch plate 40 returns to the optical transceiver 610 through the fiber 600 again. The optical transceiver 610 converts the return light signal (intensity) into an electric signal and sends it to the above-mentioned comparator circuit (not shown). Switch plate 40 and end face 8 of bearing 80
As the distance from Oa increases, the intensity of the reflected light decreases. Thus, the displacement of the switch plate 40 can be detected.

Based on the obtained vector data, the scan start address of the screen is calculated. For example, when the tilt operation is performed in the 45-degree azimuth, the current scan start address (x0,
y0) is added with the same amount of Δx and Δy to calculate the next scan start address (x0 + Δx, y0 + Δy). At this time, the magnitudes of Δx and Δy are determined according to the ratio of the absolute value of the obtained vector data to the standard value. Next, in step S340, the video controller 17

The scroll is performed at a speed corresponding to the operation force. In this way,
The moving direction and speed of image data such as a map are controlled.

That is, in the fifth embodiment, the azimuth is determined by contacting the eight divided electrodes 820, so that the azimuth is limited to eight azimuths. Since it is detected by the output voltage ratio of the element, the sixth
As in the embodiment, the designated direction can be made continuous. Further, it is possible to realize an ergonomic operation of moving the screen at a speed corresponding to the magnitude of the stress applied to the piezoelectric element. Further, this detection element does not require a power supply, and the stress caused by a human operation acts as electric power, and the electric signal is transmitted to the computer device, so that power saving can also be realized.
