DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a remote control device used for remote control of a fan, an air conditioner, and the like.

[0002]

2. Description of the Related Art FIG. 6 is a block diagram showing a configuration example of a conventional remote control device. The remote control device includes a vibration detection unit 12 that detects a touch by a user by vibration.
A switch circuit 6 including an operation switch and outputting a signal in accordance with the operation of the operation switch; an LED 7 having a built-in operation switch to illuminate the operation switch; and operating a radio signal or an optical signal in accordance with the operation of the operation switch A transmitting circuit 8 for transmitting to a target device, a vibration detecting unit 12 and a switch circuit 6
And a control unit 1 comprising a microcomputer that processes signals from the microcomputer and controls lighting of the LED 7 and drive control of the transmission circuit 8.

The vibration detecting unit 12 has a contact 2 for detecting vibration, and a side (output side) of the contact 2 connected to the control unit 1.
Are connected to a power supply S through a resistor 30, and the other terminal is grounded. For example, as shown in FIG. 3, the contact 2 contacts the mercury 10 stored in the metal container 9 and contacts the mercury 10 when the remote control device is placed in a fixed position, and connects the mercury 10 to the metal container 9. It is a mercury contact (normally closed contact) composed of the current-carrying rod 11 for maintaining the state.

[0004] Such a remote control device is operated by a battery, but in a standby state, an oscillator (not shown) of a microcomputer of the control unit 1 is stopped and a clock is stopped in order to prevent consumption of the battery. . When the user touches and the vibration causes the contact 2 of the vibration detecting unit 12 to be turned off / on, or when the operation switch is operated, the oscillator is started, and the operation of the oscillator is stabilized. Is activated. After the program is started, a radio signal or an optical signal corresponding to the operation of the operation switch is transmitted to the operation target device.

Since the time required for the operation of the microcomputer to start after the oscillator is started and the operation of the microcomputer is stabilized is sufficiently shorter than the time for which the operation switch is operated, the program can be used for any of the programs. It is possible to recognize whether the operation switch has been operated. When the oscillator is started by turning off / on the contact 2 of the vibration detection unit 12, the LED 7 is turned on so that the user can visually recognize the operation switch.

[0006] When the signal level from the vibration detection unit 12 changes from H level to L level, the microcomputer of the control unit 1 starts up assuming that the user has touched it. The contact 2 of the vibration detecting unit 12 is on (normally closed contact) when the remote control device is located at a fixed position, and the resistance 3
A current flows to the ground terminal through 0 (for example, 100 kΩ). Thus, the signal level from the vibration detection unit 12 is at the L level. When the remote control device is touched by the user, the vibration causes the contact 2 to be turned off / on at least once as shown in FIG. At this time, the signal level from the vibration detection unit 12 changes from L level → H level → L
At this level, the microcomputer of the control unit 1 is activated.

[0007]

As described above, the contact 2 of the vibration detecting section 12 is turned on when the remote control device is in a fixed position, and the current is supplied to the ground terminal through the resistor 30. , There is a problem that battery consumption is large.

After the program of the microcomputer is started, it is necessary to determine which of the detection signal of the vibration detecting unit 12 and the operation of the operation switch has been used in order to determine whether to turn on the LED 7 or not. However, as shown in FIG. 7, since the microcomputer of the control unit 1 is activated by the change of the detection signal from the H level to the L level, the program is activated to indicate that the detection signal has changed. To detect at a point in time, it is necessary to provide a delay circuit. However, even if a delay circuit is provided to extend the time for determining that a change from H level to L level has occurred, as shown in FIG. 5, the time for which the determination can be completed before the program is started is terminated. As a result, it may not be possible to detect that the change from the H level to the L level has occurred, and the LED 7 may not be able to be turned on.

The present invention has been made in view of the above circumstances, and it is an object of the first invention to provide a remote control device with low battery consumption. A second object of the present invention is to provide a remote control device that can turn on a light emitter that illuminates an operation switch after a microcomputer program is started by a detection signal of a vibration detection unit.
