A plurality of pushbutton switches, a mode changeover switch having an operation unit for switching the function of the electric circuit to a plurality of modes, and a slidably supported in the housing in proximity to the see-through window, and accompanying the mode changeover. A remote control device comprising: a display board provided with a plurality of displays corresponding to the respective push-button switches; and a connecting device for connecting the operation section and the display board, wherein the display board is turned around the connecting section. Then, the display portion of the display panel protrudes outside the side of the housing.

[0005]

According to the above construction, the display portion of the display plate is exposed by rotating the display plate about the connecting portion and projecting the display plate to the outside of the housing. Change the settings, for example, from the first channel of the TV to the first
When the channel is changed to 2 channels, the display “1” on the display plate corresponding to the push button is removed and removed.
2) is attached by pasting or the like. Thereafter, the operation of changing the display can be completed by rotating the display plate and storing it in the housing.

[0007] Reference numeral 7 denotes a circuit board made of a copper-clad laminate for a printed wiring board housed in the housing 1, which includes an electric circuit 8 for a push button switch, a plurality of push button switches 9 including a tact switch and the like, Sliding mode changeover switch 10 for switching the function of circuit 8 to a plurality of modes
And a diode 52 for signal emission. The push button switch 9 uses a plurality of independent switches. In addition, although not shown, a plurality of pairs of switch electrodes are formed on the circuit board and provided with carbon material contacts corresponding to the switch electrodes. A plurality of push button switches made of a silicone rubber material may be integrally connected.

[0008] The mode changeover switch 10 is
1 is protruded from the through hole 4, and the operation unit 11 is reciprocated in two steps in the direction indicated by the solid line arrow to switch the function of the electric circuit 8 to a plurality of modes (two types). As the plurality of modes, for example, for a television receiver (T
V) and for video tape recorders (VTR) and teletext receivers. Examples of display of push buttons corresponding to the TV mode include video input switching (video 1, video 2), channel preset (setting), and audio switching. There are, for example, display examples of the push button corresponding to the VTR mode.
There are recording, playback, fast forward, rewind, and the like. In the teletext mode, display examples such as a table of contents, subtitles, and page feed may be made to correspond respectively. In the embodiment, the example in which the operation unit 11 is provided on the lower right surface is shown. However, the operation unit 11 may be arranged at another place or side surface of the plane.

Reference numeral 14 denotes a display plate made of an opaque and flexible thin plate made of a synthetic resin or the like. A connecting portion 15 formed by a small hole or the like is formed at one corner, and a pair of inner and lower surfaces of the upper housing 3 are provided. The concave groove 32 is slidably supported in the vicinity of the see-through window 5 and the lens button 6, and the display 12 corresponding to the respective see-through window 5 and lens button 6 is provided on the surface as the mode is switched by sliding the operation unit 11. And 13. The displays 12 and 13 are displayed along the sliding direction of the operation unit 11, and when the operation unit 11 is slid to one end of the mode changeover switch 10, the display 12 appears just below the corresponding see-through window 5 and lens button 6. The display 13 appears when the operation unit 11 is slid to the other end of the mode changeover switch 10. The displays 12 and 13 may be formed on the back surface of the display plate 14 by using a transparent base material.

Reference numeral 16 denotes a connecting device made of a synthetic resin for connecting the operation unit 11 and the display panel 14.
7 is locked to the connecting portion 15. 18 is a spring plate,
One end is fixed to the inner surface of the upper housing 3, and the other end is pressed against the notch 19 of the display panel 14. As a result, the display plate 14 is biased to one side, and the cover 3
By rotating and opening 0, it can be rotated in the direction indicated by the dashed-dotted arrow with the connecting portion 15 as an axis, and can be projected outside the side of the housing 1. Reference numeral 20 denotes a pedestal, which is formed so as to protrude from the bottom of the lower housing 2, and fixes the circuit board 7 with screws 21. Reference numeral 33 denotes a guide rib which protrudes from the inner surface of the lid 30 and fits the display plate 14 into the concave groove 32 when the lid 30 is opened and closed.

FIG. 5 shows an example of an electric circuit diagram in which a part of a remote control device is omitted. Reference numeral 51 denotes a known remote control pulse generation circuit which generates, for example, an 8-bit pulse width coded signal. Oscillates a sub-carrier having a frequency of about 38 KHz, modulates the sub-carrier with a remote control pulse, and outputs the same through a transistor 53 to drive an infrared light emitting diode 52; Mode switch 10 according to each device such as electronic device
, The remote control infrared signal corresponding to the operated push button switch 9 is emitted from the light emitting diode 52.

Now, one of the push buttons is a channel 1 of a television.
When changing the channel set to channel 12 to the channel 12, after pressing the storage push button, the change source push button corresponding to the channel 1 and the push button corresponding to the change destination channel 12 are sequentially pressed, and finally the storage Pressing the push button again completes the operation, and the push button corresponding to the channel 1 includes channel 1
The channel 2 can be configured so that the channel 1 is shifted to the push button corresponding to the channel 12 while the channel 2 is shifted. During this time, the code signal to be transmitted stored in the non-volatile memory or the RAM (random access memory) of the circuit in the remote control device can be replaced between the two push buttons.

Alternatively, when replacing one of the push buttons with the setting of the other button, for example, changing the one set to the channel 1 of the television as the playback button of the VTR, press the memory push button. After that, the change source push button corresponding to the channel 1 and the push button corresponding to the change destination channel 1 are sequentially pressed again, and the settings previously stored by the channel up / down buttons are successively set to the VT.
It changes until it reaches the setting part of R reproduction. Finally, by pressing the memory push button again, a series of operations can be completed.

In this changing work process, infrared light is emitted as a remote control signal, so that it is possible to confirm whether the desired setting has been reached. When changing the channel set to the channel 1 of the television as the channel 42, after pressing the memory push button, the change source push button corresponding to the channel 1 and the change destination channel 1 corresponding to the channel 1 again are changed. After the push buttons are sequentially pressed, the channel buttons 1 to 10 (10 functions as a 0 button) are used as so-called ten-keys. In this case, after the buttons 4 and 2 are continuously pressed, By pressing the memory push button again, the setting button of channel 1 can be changed to the setting button of channel 42 and the operation can be completed.

[0015]

As described above, according to the present invention, the display corresponding to each push-button switch can be easily changed and set by turning the display plate and projecting it out of the remote control device housing. Thus, there is an effect that a remote control device capable of setting switching display can be obtained.
