[Example] Hereinafter, an example of this invention will be described based on the drawings.

1 to 3 are diagrams for explaining the first embodiment. This embodiment is an example of application as a remote control device for in-vehicle audio equipment.
A total of three types are configured: B for volume adjustment at the bottom right of the figure, and C for seek (tuning on a radio receiver, music selection on a compact disc, etc.) on the left side of the figure.

Therefore, as a representative example of these, the configuration of a remote control device A for function switching will be explained with reference to FIG.

In the figure, 1 is a planar hexagonal main body of a remote control device;
It is divided into upper and lower parts by a, and the upper part is the mounting part R ₁ of the printed circuit board 2, and the lower part is the mounting part R ₂ of the thin battery 3. The lower part of the mounting portion _R2 is covered by a cover 1b. A push switch 4 is attached to the center of the top surface of the printed circuit board 2.
In addition, an infrared light emitting diode (transmission unit; hereinafter referred to as "light emitting diode") 6 is attached to the upper end of the printed circuit board 2, and a single-function remote control IC chip (for function switching only) is attached to the lower surface of the printed circuit board 2. A control unit) 5 is attached, and these are electrically connected to the battery 3.
The push switch 4 is the push switch 4a.
is facing upward and turns ON when the push rod 4a is pushed downward. IC chip 5
When the push switch 4 is turned on, the light emitting diode 6 emits infrared rays coded as a control signal for switching functions. The contents of the control signal will be described later.

Reference numeral 7 denotes a hexagonal push button, which is attached to the periphery of the main body 1 so as to cover the upper part of the mounting portion _R1 of the main body 1. The attachment part is the main body 1
It has a structure in which a claw 7a provided on the circumferential portion of the push button 7 is fitted into a mounting hole 1d formed in the circumferential wall portion 1c of the push button 7. The claw 7a is vertically movable within the mounting hole 1d by a predetermined amount. A display window hole 7b is formed in the upper part of the push button 7, and the light emitted by the light emitting diode 6 is outputted to the outside through the display window hole 7b. This light emitting diode 6 is connected to the IC chip 5.

A spring 8 is attached between the printed circuit board 2 and the push button 7 to bias the push button 7 upward. Further, the lower surface of the main body 1 is provided with attachment means 9 for detachably attaching the main body 1 to a predetermined position in the vehicle. This attachment means 9 is a magnet, double-sided adhesive tape, etc.
It is removably attached to the inside of a car door or the center of a handle.

Next, the operation of the function switching remote control device A configured as described above will be explained.

When the remote control device A is not used, the main body 1 is attached to a desired position inside the vehicle by the attachment means 9. At this time, the push button 7 is held in the upper position by the spring 8.
Therefore, the push switch 4 remains OFF, the IC chip 5 does not operate, and the light emitting diode 6 does not transmit a control signal.

When switching the function of the audio equipment, the main body 1 is removed and held in the hand, the light emitting diode 6 is directed toward the audio equipment, and the push button 7 is pushed downward. As a result, the push rod 4a is pushed and the push switch 4 is turned on.
Then, the IC chip 5 operates and the light emitting diode 6 issues a control signal for switching the function. The audio equipment determines this control signal and switches its functions in a predetermined order every time it receives it. For example, each time this control signal is received, the cassette tape player, tuner, and compact disk player are switched and operated in a predetermined order.

Next, the remote control device B for volume adjustment at the lower right in FIG. 2 and the remote control device C for seek at the left side in the same figure will be explained. These are basically constructed in the same way as the remote control device A for function switching described above, and as shown in FIG. As a result, they can be installed all at once at desired locations within the vehicle.

However, two push switches 4 are attached to each of these remote control devices B and C, and the second push button 7 of each
When the right part of the figure, that is, the part written as "down" is pressed, the push button 7 tilts to one side, one of the down adjustment push switches 4 is turned on, and each push button 7 is turned on. When you press the left part in Figure 2, that is, the part written as "up", push button 7
tilts to the other side, and the other push switch 4 for adjusting the top is turned on. In addition, these remote control devices B and C are equipped with an IC chip 5.
As such, single-function devices are installed, one for volume adjustment and one for seek. Here, seek means selecting a station on a radio receiver or selecting a song on a compact disc, and the direction is expressed as seek down or seek up.

The former IC chip 5 dedicated to volume adjustment is
When the push switch 4 for adjusting the volume down is turned ON, an infrared ray coded as a control signal for adjusting the volume down is emitted from the light emitting diode 6, and when the push switch 4 for adjusting the volume up is turned ON. , the light emitting diode 6 emits coded infrared rays as a control signal for adjusting the volume up. On the other hand, the latter seek-only IC chip 5 is
When push switch 4 for down adjustment is turned on, infrared rays coded as a seek down control signal are emitted from light emitting diode 6, and push switch 4 for up adjustment is turned on.
When turned on, the light emitting diode 6 emits coded infrared rays as a seek-up control signal.

The audio equipment discriminates the control signals from these remote control devices B and C and automatically adjusts the volume and performs the seek operation. That is, when a control signal for adjusting the volume down is received, the volume is gradually lowered at a predetermined rate during reception, and when a control signal for adjusting the volume up is received, the volume is gradually lowered at a predetermined rate during reception. Gradually increase the volume at a rate of . Also, each time a seek-down control signal is received, the radio receiver's channel selection or compact disc's song selection is shifted down one by one, and each time a seek-up control signal is received, the radio Shift the channel selection on the receiver or the song selection on the compact disk one by one in the upward direction.

By the way, it is necessary that the relationship between the control signal and the control content be set in advance between the remote control devices A, B, C and the audio equipment as described above.

Therefore, the setting method will be explained based on FIG. 3.

The audio device 10 is equipped with an infrared light receiving section 11, a microcomputer control section 12, and a key matrix 13. When setting the relationship between control signals and control contents, the control contents to be set are input from the key matrix 13 to the microcomputer control section 12, and the control signals associated with the control contents are transmitted to one of the remote control devices A, B, and C. Send from here. As a result, the microcomputer control unit 12 sets and stores the relationship between the control signal and the control content.
In this way, the relationships between all control signals and control contents are set and stored.
