The switch scanning means 8 detects this switch input, and the timer 9 starts counting. The latch means 7 of the timer latches the count value of the timer 9 when the action piece of the ID generation switch 6 is separated, and stores the count value in the memory 10 as an ID. Such a remote control device operates as follows. That is, when the ID generation switch 6 is turned on, the microcomputer 11 detects the switch input by the switch scanning means 8 and operates the timer 9. That is, the time from when the ID generation switch 6 is pressed to when it is separated is counted by the timer 9 (counter) in the microcomputer.

The ID generation value is determined using the latch means 7 of the timer when the ID generation switch 6 is released, and the value of the timer 9 at that time is stored in the memory 10 as an ID. The ID data is supplied from the memory 10 to the data setting means 3, where predetermined data and an ID code are set, and the data is set as a modulated wave via the waveform output means 5 and the infrared light emitting diode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a remote control device according to the present invention will be described below in detail with reference to FIGS. In FIG. 1, parts corresponding to those of the conventional remote control device shown in FIG.
The detailed description is omitted. In FIG. 1, a key matrix 1 is a group of switches for performing operations corresponding to a remote control mode such as channel selection, volume adjustment, power on / off, and the like. The key matrix 1 has a predetermined shape on a panel of a commander housing (not shown). Are arranged. Then, a key input in a predetermined remote control mode is input to the key scanning means 2 in the microcomputer 11 constituting the remote control device.

When a key is input from the key matrix 1, the key scan means 2 sequentially outputs a key matrix scan signal, determines which output signal is input to which key matrix, and outputs data corresponding to each key. The code is set by the data setting means 3. The set data code is modulated at a predetermined frequency via the waveform generating means 4 and the waveform output means 5, and then supplied to the infrared light emitting diode, and transmitted to the remote control signal receiving device side. One end of the ID generating switch 6 is grounded, and the ID generating switch 6 is brought into a conductive state by the pressing thickness of the action piece, and the microcomputer 11
Switch input.

The switch scanning means 8 detects the switch input, and the timer 9 starts counting. The latch means 7 of the timer latches the count value of the timer 9 when the action piece of the ID generation switch 6 is separated, and stores the count value in the memory 10 as an ID. Here, an initial ID value is previously stored in the memory 10 by the initial ID value setting means 12 at the time of shipment, and the initial ID value is set at the same time when the power of the remote control device is turned on and a predetermined setting is made. This enables the operation of the remote control device.

Also, the count value of the timer 9 latched by the timer latch means 7 is output to the appropriate ID determination means 13.
Thus, it is determined whether or not the ID is the same as the ID initial value stored in the memory 10. If the ID is not the same, it is determined that the ID is proper and stored in the memory 10. Improper if equal
D is determined, the data is canceled once, and a request for re-registration is made. One embodiment of the remote control device of the present invention is configured as described above, and operates as follows.

When the power of the remote control device is turned on, an initial ID value is previously stored in the memory 10 by the initial ID value setting means 12 at the time of shipment.
In step S1, an initial ID value is set immediately in step S1. When re-registering the ID in step S2, the count value of the timer 9 from the pressing of the ID generation switch 6 to the separation in step S3 is latched by the latch means 7 of the timer.
Whether the value of the timer 9 at this time is the same as the initial value of the ID stored in the memory 10 is judged by the proper ID judging means 13. If not, the proper ID is judged.
Store to 0. If they are the same, it is determined to be an incorrect ID,
Once the data is canceled, the operator is requested to re-register (not shown).

The ID data is supplied from the memory 10 to the data setting means 3. The data setting means 3 sets predetermined data and an ID code. The data is set as a modulated wave via the waveform output means 5 and the infrared light emitting diode. The data is transmitted to a receiving device (not shown). At this time, the on-power source of the remote control device, at the same time I predetermined settings that made
Since the D initial value is set, the operator can immediately use the remote control device without setting an ID code.

In FIG. 3, as shown in an example of code use, a code in which all 15 bits are zero is used as an initial ID value, and other codes are used as random codes. Here, the first bit is a parity bit, and the other 14 bits are I bits.
Let it be a D code. Since all bits of the ID initial value are set to zero, the count value of the timer 9 from the pressing of the ID generation switch 6 to the separation is latched by the latch means 7 of the timer, and the ID is newly registered . In this case, all bits are zero.
B) Cancel the data and request re-registration
Therefore , it is possible to avoid coincidence with the ID initial value. Although the receiving device is not specifically described in the above example, when the receiving device is a portable electronic device, the receiving device can be appropriately carried and used together with the remote control device. According to this example, the operator can immediately use the remote control device with the preset ID code initial value without setting the ID code. Further, according to this example, when necessary, an ID code different from the initial ID code value can be set.

The above embodiment is an example of the present invention.
It goes without saying that various other configurations can be adopted without departing from the spirit of the present invention.

According to the present invention, the operator can immediately use the remote control device according to the preset ID code initial value without setting the ID code.
Further, according to the present invention, when necessary, an ID code different from the initial ID code value can be set.
