And a pedestal 23 of the operation unit.

Normally, the nosepiece portion 1 is an electronic device body 2
It is used by being attached to the cradle 23. At this time, by connecting the electrode 14 and the electrode 22, a key operation control signal from the nose piece portion 1 to the audio device body 2 and a display signal from the electronic device body 2 to the nose piece portion 1 are transmitted and received.

FIG. 2 is a block diagram showing a circuit diagram for performing such an operation. Reference numeral 1a is a circuit provided in the nosepiece portion 1, 11 is a light emitting diode, and 12 is a light emitting diode.
a is a rotary volume section, 12b is a push volume section, 12c is a plurality of keys for switching between a radio tuner and a tape player, selecting a radio station, and performing various operations such as play / pause during tape play. It is an operation unit provided.

Reference numeral 13 is an indicator for displaying the operating state, the reception frequency, etc., 14a, 14b, 14c are electrodes, and 15 is a microcomputer. The microcomputer 15 is pushed with the rotary volume section 12a by a switching control signal described later. A switching control unit 15a is provided for switching between use selection with the expression volume unit 12b and switching of a method of transmitting a key operation control signal from the nose piece unit 1 to the audio device body 2. Reference numerals 16 and 17 are buffer amplifiers, 18 is a switch, 19 is a resistor, 20 is a transistor, 22 is a battery as a power source of the circuit 1a, and 27 is a diode inserted in the battery 22 in series.

Next, 2a is a circuit provided in the electronic equipment main body 2, 22a, 22b and 22c are electrodes respectively, and 23 is a microcomputer. The microcomputer 23 receives a switching control signal, which will be described later, from the nosepiece section 1. A switching control unit 23a for switching the route for receiving the transmission signal is provided. Reference numeral 21 is a phototransistor for receiving infrared rays, 24 is a switch, 25 is a receiving IC, and 26 is a resistor.

Now, the nosepiece part 1 is an electronic device body 2
Electrode 14a, 14b, 14c, the electrode 2
2a, 22b, 22c, and in this state, the switches 18 and 24 are both configured to be switched to the a side by means described later. Electrode 22c
Since the electrode of the electronic device main body 2 is given to, the power is supplied to the electrode 14c and is used as the circuit power supply of the operation unit 1. A display signal output from the microcomputer 23 is applied to the electrode 22a, and this signal is input to the buffer amplifier 16 via the electrode 14a.
5 is output to the display 13 and displayed.

By operating any one of a plurality of keys of the operating portion 12c of the nosepiece portion 1, an operating signal is sent to the microcomputer 15 and converted into a control signal, and the control signal is sent to the electrode 14b via the buffer amplifier 17. Is given. The signal of the electrode 14b is sent to the electrode 22b and input to the microcomputer 23 via the switch 24 to control the electronic device body 2.

The microcomputer 15 uses the switching control section 15a to select the use of the two types of volume means provided in the circuit 1a, that is, the rotary type volume section 12a and the push type volume section 12b. When mounted on the device body 2,
By detecting that the display signal is input to the microcomputer 15, the rotary volume unit 12a is controlled to be selectively used. Further, the contacts of the switches 18 and 24 are switched to the side a because the display signal is input to the microcomputer 15, and the microcomputer 23 on the electronic device main body 2 side outputs the display signal. It is detected that the switching control units 15a and 23a of the microcomputers 15 and 23 respectively detect that the switch 1
This is done by switching 8 and 24.

Here, by setting the voltage applied to the electrode 14c higher than the voltage of the battery 22 of the power source of the circuit 1a of the nosepiece section 1, the diode 27 becomes reverse biased, and the battery 22 is disconnected. Wear is suppressed. Further, since both the switches 18 and 24 are switched to the a side, the transistor 20, the light emitting diode 11, the phototransistor 21, and the reception IC 25 are in a cutoff state.

When the nosepiece section 1 is used as a remote control device, the nosepiece 1 is removed from the electronic equipment body 2. Therefore, 14a, 14b, 14c and 22
Since the electrodes a, 22b, and 22c are all cut off, the display signal input to the microcomputer 15 via the electrode 14a of the circuit 1a of the nosepiece portion 1 and the buffer amplifier 17 is not input either, so this is detected. The microcomputer 15 sends a signal for switching the switch 18 to the switching control unit 15a and switches its contact from a to b. Similarly, the switching control unit 23a of the microcomputer 23 of the circuit 2a of the electronic device body 2 switches the contact of the switch 24 from a to b when the microcomputer 23 stops outputting the display signal. Therefore, in the circuit 2a of the electronic device body 2, a circuit state in which the output signal of the phototransistor 21 is received by the receiving IC 25 and input to the microcomputer 23 is set.

In the circuit 1a of the nosepiece section 1,
Power is supplied to each circuit portion from the battery 22 via the diode 27, and the output of the buffer amplifier 17 is the switch 18
Is input to the base of the transistor 20 via the resistor 19. When the light output from the light emitting diode 11 of the nose piece portion 1 shown in FIG. 1 is directed in such a circuit state so as to hit the phototransistor 21 of the electronic device main body 2 and the key of the operation portion 12c is operated, an operation signal is output. Is input to the microcomputer 15, converted into a control signal, and output to the buffer amplifier 17. The output signal of the buffer amplifier 17 is given to the base of the transistor 20 via the switch 18 and the resistor 19 to cause the light emitting diode 11 to emit light.
The light emitted from the light emitting diode 11 is the phototransistor 21.
The received light signal is input to the receiving IC 25 and a control signal is sent to the microcomputer 23 via the switch 24 to control the electronic device main body 2.

The microcomputer 15 uses the switching control unit 15a to select the use of the two types of volume means provided in the circuit 1a, that is, the rotary volume unit 12a and the push volume unit 12b.
In the state in which is removed from the electronic device main body 2 and is used as a remote control device, it is controlled that the push type volume unit 12b is selectively used by detecting that the display signal is not input to the microcomputer 15.

As described above, when the nose piece portion 1 is attached to the electronic equipment main body 2, the rotary type volume 12a is used to obtain an excellent operability and a detachable remote control device. In the case of use, a usage state in which power consumption is reduced by using the push-type volume 12b can be obtained.

The switches 18 and 24 can be switched as follows.
In the above-described embodiment, the configuration is performed by detecting the presence or absence of the display signal, but this is automatically switched by using the crimping force accompanying the mounting of the nose piece portion 1 on the electronic device body 2. You may do it. Further, although the volume adjustment, that is, the volume control has been described as an example of the adjusting means, it is needless to say that this is not limited to the volume adjustment and can be used for adjusting the sound quality and the like.

Further, in the above embodiments, the front panel portion of the audio equipment for vehicle is a detachable nose piece, and when it is detached, it is used as a remote control device. However, the nose piece portion is detached. Alternatively, a remote control device having only required operation means may be detachably attached to an appropriate place of the electronic equipment main body, and the remote control device may be equipped with the same two types of volumes as described above.

[0023]

As described above, according to the present invention, when the remote control device is used in a state where it is attached to the main body of the electronic device, the rotary type volume which has excellent operability is detached and used as a remote control. Since it is possible to use a push-type volume that consumes less power and is not susceptible to erroneous operation, it is possible to obtain a remote control device that can be attached or detached.
