  On the other hand, the display panel 9 of the input display device 4 is disposed on a circuit board 10 provided at the bottom of the device case 1 and corresponds to the touch panel 5, as shown in FIG. It is configured to be electrically connected. The display panel 9 is composed of a flat display element such as a liquid crystal display element or an organic EL (electroluminescence) display element, and is configured to display information electro-optically.

  As a result, the input display device 4 is configured such that information displayed on the display panel 9 can be seen from above the device case 1 through the touch panel 5. The circuit board 10 is electrically connected to the display panel 9 and electrically connected to the plurality of pressure detectors 6, and various electronic components (not shown) required for the electronic device. ) Is installed.

Next, the circuit configuration of the electronic apparatus will be described with reference to the block diagram of FIG.
The electronic device includes a CPU (Central Processing Unit) and the like, and performs overall control of the input display device 4, and various programs executed by the CPU of the control unit 20 and initial settings. And a storage unit 21 that stores data and the like and provides a working memory space to the CPU of the control unit 20.

  In addition, the electronic device includes a pressure detection unit 22 that detects a pressure corresponding to a touch operation on the touch panel 5 by a plurality of pressure detection units 6 and inputs a detection signal to the control unit 20 as pressure data, and a control unit. And a display panel 9 for displaying information based on a control signal from 20. The control unit 20 is configured to perform control processing for calculating the coordinate position of the location where the touch panel 5 is touched based on the detection signals of the plurality of pressure detection units 6 given from the pressure detection unit 22. .

Next, control processing by touch operation of the touch panel 5 in this electronic device will be described with reference to an operation flow shown in FIG. In this case, FIG. 8 is a diagram illustrating a procedure of control processing executed by the CPU of the control unit 20.
This control process starts when the touch panel 5 is touched. In step S1, the plurality of pressure detection units 6 of the pressure detection unit 22 detect the pressure in response to the touch operation of the touch panel 5, and the detection signal is used as the pressure signal. The data is input to the control unit 20 as data.

  That is, in step S <b> 1, when the touch panel 5 is touched, pressure is applied to the plurality of pressure detection units 6 of the pressure detection unit 22 according to the touch position of the touch panel 5. For example, when the center of the touch panel 5 is touched, a uniform pressure is applied to the plurality of pressure detection units 6, and no difference occurs between the pressures of the plurality of pressure detection units 6.

  In addition, when a position shifted from the center portion of the touch panel 5 is touched, different pressures are applied to the plurality of pressure detection units 6, and differences occur in the pressures of the plurality of pressure detection units 6. As a result, the detection signals respectively detected by the plurality of pressure detection units 6 are input to the control unit 20 as pressure data.

  When the detection signals from the plurality of pressure detection units 6 of the pressure detection unit 22 are given to the control unit 20, the process proceeds to step S2, and in this step S2, pressure data that is detection signals from the plurality of pressure detection units 6 is converted. Based on this, the control unit 20 performs arithmetic processing to calculate the coordinates of the touch position of the touch panel 5. At this time, the coordinates of the touch position of the touch panel 5 are calculated based on the pressure differences of the plurality of pressure detection units 6.

  For example, when the pressures of the plurality of pressure detection units 6 are the same and there is no pressure difference, the coordinates of the touch position of the touch panel 5 are specified as the center of the touch panel 5. Further, when there are pressure differences of the plurality of pressure detection units 6, the coordinates of the touch position of the touch panel 5 are calculated according to the pressure differences of the pressure detection units 6 and the coordinates of the touch position are specified.

  When the coordinates of the touch position of the touch panel 5 are specified in step S2, the process proceeds to step S3, and information corresponding to the coordinates of the touch panel 5 specified in step S3 is displayed on the display panel 9. That is, when the information displayed on the display panel 9 is seen from above the device case 1 through the touch panel 5, the information of the place touch-operated on the touch panel 5 is specified among the information displayed on the display panel 9. Information corresponding to the designated location is selected and displayed on the display panel 9.

Next, the case where the touch panel 5 is replaced in the input display device 4 in the electronic apparatus will be described.
In this case, first, the operation buttons 8b of the plurality of support release members 8 projecting downward from the device case 1 are respectively pushed down against the spring force of the spring members 7a of the plurality of biasing support members 7. . Then, the release shaft 8a of the support release member 8 pulls down the mounting plate 7c of the biasing support member 7 and compresses the spring member 7a.

  Thereby, the pressure detection unit 6 provided on the mounting plate 7c of the urging support member 7 is pulled down, the elastic push-up of the pressure detection unit 6 with respect to the touch panel 5 is released, and the touch panel 5 is slidable. Become. In this state, the touch panel 5 is slid toward the panel insertion opening 2b side of the upper case 2 by hand or finger through the opening 2a of the upper case 2.

  Then, since each guide plate 14b of each panel guide portion 14 in the position restricting guide member 12 provided on both sides of the panel insertion opening 2b is pushed by the sliding operation of the touch panel 5, each guide plate 14b is centered on the support shaft 14a. While rotating and opening, the touch panel 5 protrudes outside the device case 1 through the panel insertion slot 2b. Thereby, the touch panel 5 can be taken out from the device case 1.

In addition, since the biasing support member 7 that elastically pushes up and supports each of the plurality of pressure detection units 6 can be pushed down by the support release member 8 to release the elastic contact force of the pressure detection unit 6 with respect to the touch panel 5. Can be easily slid, whereby the touch panel 5 can be easily replaced.

  In this case, by including a control unit 20 that calculates the coordinate position of the location where the touch panel 5 is touched based on the pressure data detected by the plurality of pressure detection units 6 according to the touch operation of the touch panel 5. Even if the touch electrode is not provided on the touch panel 5, the coordinates of the touch position of the touch panel 5 can be accurately and reliably calculated based on the pressure data detected by the plurality of pressure detection units 6. For this reason, the structure of the touch panel 5 is simplified, the touch panel 5 can be manufactured at low cost, and the durability of the touch panel 5 can be enhanced.

  In addition, the input display device 4 includes the position regulation guide member 12 that guides the touch panel 5 with respect to the device case 1 and regulates the position in the surface direction of the touch panel 5. The touch panel 5 can be satisfactorily guided by the position restriction guide member 12, and the position can be accurately and surely placed in the device case 1.

  In this case, the position regulation guide member 12 is provided on the side surface of the device case 1, the panel guide portion 14 for guiding the touch panel 5 into the device case 1 from the panel insertion port 2 b through which the touch panel 5 is inserted, and the panel of the device case 1.
