【Example】

An embodiment of the present invention will be described below with reference to the drawings. Figures 1 to 3 1 is the synthetic resin housing of the remote control device, and the lower housing has an open top. 2, and an upper casing 3 that is fitted and coupled to the lower casing 2 with its lower surface open. . The upper housing 3 has a plurality of transparent windows 5 and a plurality of openings 6 on the upper surface formed in a substantially flat plate shape. At the same time, a through hole 4 is provided at the corner, and the transparent window 5 is provided at one side. A plurality of punch holes 7 are provided corresponding to each other. Then, the through hole 4, the opening 6 and the cutout hole 7, at least the part corresponding to the transparent window 5 is provided with a transparent cover. Bar 8 is attached. Note that instead of the cover 8, for example, only the transparent window 5 may be used. Even if you attach a transparent lens and enlarge the display corresponding to the push button to make it easier to see. good. 9 is a circuit board made of a copper-clad laminate for printed wiring boards, with a pair of switches installed nearby. The push button switch electric circuit 10 has a plurality of push button switch electrodes 11.

[0007] 14 is a push button switch device that connects a plurality of push button switches 29 together; The button switch 29 has one end protruding outward from the opening 6 of the upper housing 3, and the other end protruding from the pair of buttons. a push button part 13 equipped with a carbon material contact point 12 corresponding to the switch electrode 11; It consists of a thin funnel-shaped part 15 extending from the lower part of the push button part 13 and a base part 30, It is integrally molded from silicone rubber material, and each push button switch is connected via the base 30. A switch 29 is integrally connected. The funnel-shaped portion 15 does not press the push button portion 13. In this state, maintain the space between the contact 12 and the switch electrode 11, and press the push button part 13. The contact 12 and the switch electrode 11 are electrically deformed and a click feeling is generated. When the push button part 13 is released from the press, it restores to its original shape and the electrical connection is completed. is cut off. In addition, in FIGS. 1 and 2, parts 1 to 12 are omitted from illustration. Push button for direct channel selection, power on/off push button, volume increase/decrease There are push buttons etc. that perform At the same time, the silicone rubber material is extended and formed integrally with the push button switch device 14. This allows the configuration to be made simpler.

[0008] Reference numeral 16 denotes a sliding mode changeover switch, which is attached to the circuit board 9 and The operating portion 17 that functions as the air circuit 10 projects from the through hole 4 in the direction indicated by the solid arrow. Slide back and forth in 3 stages to switch between multiple modes (3 types). multiple modes For example, for television receivers (TV) and video tape recorders. (VTR), for teletext receivers, and as an example of the push button display corresponding to TV mode. is for video input switching (Video 1, Video 2), channel preset (setting) Examples of push button displays that correspond to VTR mode include recording, audio switching, etc. There are playback, fast forward, rewind, etc. Teletext modes include table of contents, subtitles, and page turn. It is sufficient to correspond to display examples such as the following. In addition, in the embodiment, the operation unit 17 is located in the lower right direction. Although the example shown is shown in stomach.

[0009] Reference numeral 18 denotes a display plate made of an opaque and flexible thin plate made of synthetic resin, etc. A pair of through holes 19 corresponding to the holes 13 are formed on both sides of the inner surface of the upper casing 3. It is slidably fitted and supported in the vicinity of the transparent window 5 by a concave groove 20, and has a U-shape on the surface. A plurality of shaped portions 31 are provided. The U-shaped portion 31 is operated by sliding the operating portion 17. Equipped with displays 21 to 23 corresponding to each pushbutton switch 29 when switching the mode. The display section 32 that has been removed is fitted in such a way that it can be inserted and removed. The display section 32 is fitted into the U-shaped section 31. In the attached state, the tip in the pull-out direction is located approximately at the center of the pull-out hole 7. A knob 33 is formed protruding from the tip.

0010 24 is a connecting device made of synthetic resin, and a key-shaped locking portion 25 is connected to the small hole 2 of the display board 18. 6 to connect the operating section 17 and the display panel 18. 27 is the pedestal, bottom It is formed to protrude from the bottom of the casing 2, and the circuit board 9 is fixed with screws 28. Before The see-through window 5 and the aperture 6 are provided as a pair in a very close relationship, and each As shown in FIG. are arranged along the sliding direction. In addition, the displays 21 to 23 are It is displayed along the sliding direction of the working part 17, and is displayed on one end side of the mode changeover switch 16. When the operation unit 17 is slid, the display 21 appears directly below the corresponding transparent window 5, and , when the operation section 17 is slid to the other end side of the mode changeover switch 16, the display 23 is displayed. However, when the operating section 17 is slid to the center of the mode selector switch 16, the display 2 appears. 2 appear respectively.

[0011] Figure 4 shows an example of a partially omitted electrical circuit diagram of the remote control device. 51 is a known remote control pulse generation circuit, for example, an 8-bit It generates a pulse-width coded signal with a subcarrier at a frequency of approximately 38 KHz. Oscillates the transmitted wave and modulates this subcarrier with a remote control pulse The transistor 53 outputs the signal to drive the infrared light emitting diode 52, and the television screen is turned on. mode selection switch depending on each device such as a video receiver, VTR, or other electronic device. It corresponds to the mode changed by switch 16 and corresponds to the operated pushbutton switch 29. An infrared signal for remote control is emitted from the light emitting diode 52.

0012 Now, one of the pushbutton switches is set to channel 1 on the TV. To change to channel 12, press the memory button and then Press the corresponding change source push button and the change destination push button corresponding to channel 12 in sequence, and then press the button corresponding to the change destination channel 12. Press the memory button again to complete the process, and press the button corresponding to channel 1 again. As the channel 12 changes, the push button corresponding to the channel 12 changes to channel 1. can be configured to move. During this time, the non-volatile circuit inside this remote control device All transmissions stored in random access memory or RAM (random access memory) The code signal can be configured to be replaced between two push buttons.

[0013] Alternatively, without replacing one of the pushbuttons with the settings of the other button, you can, for example, If you want to change what is set to channel 1 as the VTR play button, After pressing the memory button, press the change source button corresponding to channel 1, and then press the change destination button again. Press the buttons corresponding to channel 1 in sequence, then press the channel up/down buttons. The pre-memorized settings are accessed one after another to the playback settings section of the VTR. Change it until you reach it. Finally, by pressing the memory button again, a series of can complete tasks.

[0014] In addition, during this process of changing, infrared light is emitted as a remote control signal. , it becomes possible to check whether the desired settings have been reached. In addition, the said TV channel If you want to change what is set to channel 1 to channel 42, press the memory button. After pressing the button, press the change source button corresponding to channel 1, and then press the change destination button again. After pressing the push buttons corresponding to channel 1 in sequence, press the push buttons corresponding to channel buttons 1 to 10 (10 functions as a 0 button. ) is used as a so-called numeric keypad, in this case, 4 and After pressing each button of 2 in succession, the memory button is finally pressed again. You can complete the process by changing the setting button for channel 1 to the setting button for channel 42.
