A battery (not shown) is housed on the lower surface of the lower case 30 covered with the lid 31. The case 30 covers the lower surface of the upper case 21 to constitute a remote control transmitter 35.

  That is, in the present invention, since the electrostatic touch panel 25 is integrally formed on the upper surface of the wiring board 23, a flexible board, a connector, and the like for connecting the electrostatic touch panel 25 to the wiring board 23 are unnecessary, and assembly is easy. The remote control transmitter 35 can be formed at a low cost.

  In the above configuration, as shown in the front view of FIG. 4, in the state where a plurality of menus, for example, a plurality of keys 42 are displayed on the display screen 41 of the electronic device 40 such as a television that is remotely operated, For example, when a finger of the left hand touches a predetermined position on the upper left side of the cover 22, a part of the electric charge of the electrostatic touch panel 25 is conducted to the finger via the elastic dielectric 27, and the capacitance of the electrode at the operated position changes. Therefore, the control means 29 detects which part of the electrostatic touch panel 25 is touched by this.

  Then, when the control unit 29 transmits a remote control signal corresponding to the finger contact position as a radio wave from the transmission unit 28 to the device and the electronic device 40 receives it, for example, a display screen corresponding to the finger contact position is displayed. The “A” key 42A displayed on the cursor 41 is displayed as a cursor.

  Further, when the upper surface of the cover 22 is pressed at this position, the cover 22 swings downward while bending the elastic dielectric 27 with the fulcrum 22A at the outer end as a fulcrum, and the inner end of the cover 22 The pressing portion 22B presses the movable contact of the switch contact 24 via the operating body 26, and the switch contact 24 is electrically connected / separated.

  Then, the control means 29 detects the electrical contact / separation of the switch contact 24, and a remote control signal different from the above is transmitted. For example, “A” is displayed on the input section 41A below the display screen 41, and the character The selection is confirmed.

By pressing this lower switch contact 24, menus such as characters can be confirmed and input by remote control.

  When the upper surface of the cover 22 is touched in this way, an elastic dielectric 27 is disposed between the electrostatic touch panel 25 that detects the contact position of the finger and the cover 22, and the finger is interposed via the elastic dielectric 27. In addition, since a part of the electric charge of the electrostatic touch panel 25 is conducted and the contact position is detected, the contact position can be reliably detected.

  That is, instead of forming a gap between the lower surface of the cover 22 and the upper surface of the electrostatic touch panel 25, an elastic dielectric 27 having an upper surface on the lower surface of the cover 22 and a lower surface in close contact with the upper surface of the electrostatic touch panel 25 is provided. By detecting a change in the capacitance of the electrode at the operation location of the electrostatic touch panel 25 by the finger through the body 27, it is possible to detect the contact position reliably with little error.

  Further, as described above, the electrostatic touch panel 25 is integrally formed on the upper surface of the wiring board 23, and a flexible board or connector for connecting the electrostatic touch panel 25 to the wiring board 23 is not necessary. The remote control transmitter 35 can be formed easily and inexpensively.

  Further, when the cover 22 is pressed, the switch 22 swings around the fulcrum 22A at the outer end while bending the elastic dielectric 27, and the switch contact 24 is electrically connected and separated. Therefore, as shown in FIG. 1, even when the position of the arrow A in the center of the cover 22 is pressed or the position of the arrow B at the end is pressed, the switch contact 24 is surely electrically connected and disconnected. It has come to be.

  That is, the cover 22 is formed not to move up and down with respect to the upper case 21 but to be swingable with the fulcrum 22A at the outer end as a fulcrum. A pressing portion 22B at one end is configured to always press the switch contact 24 vertically so that reliable electrical contact / separation can be performed.

  As described above, according to the present embodiment, the electrostatic touch panel 25 is integrally formed on the upper surface of the wiring board 23, and the elastic dielectric 27 is provided between the electrostatic touch panel 25 and the cover 22. A flexible board or connector for connecting the wiring board 25 to the wiring board 23 is not required and can be easily assembled. The elastic dielectric 27 enables a reliable contact operation of the electrostatic touch panel 25, which is simple and inexpensive. A remote control transmitter can be obtained.

  Further, by forming the cover 22 to be swingable with the fulcrum portion 22A at the end as a fulcrum, even when the end portion is pressed in addition to the center portion of the cover 22, the cover 22 swings in the same manner. Since the switch contact 24 is pressed vertically, the switch contact 24 can be securely connected and disconnected.

  In the above description, the configuration in which the substantially dome-shaped movable contact is placed on the fixed contact on the upper surface of the wiring board 23 to form the switch contact 24 has been described. However, the movable contact is formed on the lower surface above the fixed contact. The present invention can also be implemented as a configuration using various switch contacts, such as a configuration in which push buttons such as rubber are opposed to each other, or a configuration in which a single push switch is mounted on the upper surface of the wiring board 23.
