[Conventional technology]

A barcode remote control device that reads a barcode and obtains a data signal, creates a remote control data signal based on this data signal, and transfers this remote control data signal to a host device such as a TV or VTR is equipped with a battery for power supply. Many are equipped with an auto power-off circuit in order to prevent wasteful consumption.

FIG. 2 is a block diagram showing a conventional configuration of this type of barcode remote control device, which is composed of an auto power-off circuit 103, a reading processing unit 101 and a transfer processing unit 102, and is operated by turning on a power key (not shown). The power supply 21 that supplies power to the reading processing unit 101 and the transfer processing block 102 is
It is connected to the auto power-off circuit 103.

The auto power-off circuit 103 is composed of a counter circuit 12, a constant memory 13, a comparator 14, a detector 16 and a switching device 15, and the OR circuit 11 is connected to the auto power-off circuit 103. When the power key is turned on, the first reset signal v is output from the detector 16, and the switch 15 is turned on by the first reset signal v. At the same time, the first reset signal v is ORed. It is designed to be input to the circuit 11. Further, by the ON operation of the switch 15, the power is supplied from the power source 21 to the reading processing unit 101 and the transfer processing unit 102 via the power line 35.

The reading processing unit 101 is composed of a reading start key input circuit 1, a switch 2, a reading start judgment circuit 3, a reading processing circuit 4 and an OR circuit 9, and a reading start key SW.
The operation 1 is connected so that the operation signal a is input from the read start key input circuit 1 to the read start determination circuit 3 via the switch 2. By inputting the drive signal c from the reading start judgment circuit 3 to the reading processing circuit 4, the reading processing circuit 4 reads the bar code to obtain the data signal d, and the data signal d is transferred. It is adapted to be taken in and stored in the circuit 8.

Further, when the reading processing of the bar code by the reading processing circuit 4 is completed, the second reset signal 1 from the reading processing circuit 4 is supplied to the OR circuit 11 and the output Z of the OR circuit 9 as the reading start key input circuit 1 , And the transfer start key input circuit 5 and the switches 2 and 6 are connected so as to be input.

When the drive signal g is input from the transfer start determination circuit 7 to the transfer processing circuit 8, the transfer processing circuit 8
Thus, a remote control data signal h is created from the data signal d, and this remote control data signal h is transferred to the host device.

Further, when the transfer processing circuit 8 completes the transfer of the remote control data signal h, the third reset signal k from the transfer processing circuit 8 causes the switching circuit via the OR circuit 11, the transfer start key input circuit 5 and the OR circuit 10. It is connected so as to be input as an output i to 2,6.

In the barcode remote control device configured as described above, when the operator turns on a power key (not shown), the switch 15 of the auto power off circuit 103 is turned on, and the reading processing unit 1
The power supply from the power supply 21 to 01 and the transfer processing unit 102 is started.

Then, the first reset signal v is input from the detector 16 to the OR circuit 11, the counter circuit 12 starts counting, and the count value p is a predetermined count value q (for example, 25 seconds) preset in the constant memory 13. When it reaches, the comparator 14 outputs the cutoff signal r, the switch 15 is turned off, and the power supply to the reading processing unit 101 and the transfer processing unit 102 is cut off.

When the operator turns on the reading start key SW1 during the operation of the barcode remote control device, the operation signal a is input to the reading start judgment circuit 3 via the switch 2. And
When the read start determination circuit 3 determines that the operation signal a is normal, the drive signal c from the read start determination circuit 3
The reading processing circuit 4 is activated by the reading processing, the bar code is read by the reading processing circuit 4, a data signal d is obtained, and the data signal is stored in the transfer processing circuit 8. When the reading processing circuit 4 completes reading the bar code, the second reset signal l is input from the reading processing circuit 4 to the OR circuit 11, so that the counter circuit 12
Is reset and the counter circuit 12 starts counting from that point until the count value p newly reaches the predetermined count value q (for example, 25 seconds).

Next, when the operator turns on the transfer start key SW2, the operation signal e is input to the transfer start determination circuit 7 via the switch 6.

When the transfer start determination circuit 7 determines that the operation signal e is normal, the drive signal g from the transfer start determination circuit 7
Then, the transfer processing circuit 8 is activated, the data signal d is encoded by the transfer processing circuit 8, and the remote control data signal h
Is created and this remote control data signal h is transferred to the host device.

When the transfer processing circuit 8 completes the transfer of the remote control data signal h, the third reset signal k is input from the transfer processing circuit 8 to the OR circuit 11, so the counter circuit 12 is reset and the counter circuit 12 is reset. Starts counting from that point until the count value p newly reaches a predetermined count value q (for example, 25 seconds).

As described above, in the bar code remote controller shown in FIG. 2, the first reset signal v and the second reset signal l
Of the third reset signal k and the reset signal finally input to the OR circuit 11, after a predetermined time (for example, 25 seconds), the power supply 21 from the power supply 21 to the read processing unit 101 and the transfer processing unit 102 is cut off. To be done.

Therefore, it is possible to avoid wasteful supply of the power supply 21, and it is possible to perform a large number of reading processes and transfer processes within a predetermined time without having to repeatedly operate the power key, so that the bar The cord remote control device can be operated effectively and smoothly.
