PURPOSE:To prevent the misoperation by using the code showing the figures, the end signal and the like for the signal which actuates the remote control device. CONSTITUTION:The signal showing the figures is supplied and then converted into the digital signal through the code converter 10 to be then stored successively into the registers 12-0-12-(n-1) in accordance with the input frequency. Then with arrival of the end signal, the code converting circuit 10 delivers the end signal 1. Both the outputs of the digital switches 13-0-13-(m-1) and the outputs of the registers 12-0-12-(n-1) are supplied to the matchers 14-0-14-(m-1). And only the matcher having a coincidence between the both outputs delivers the output. Then the relays 16-0-16-(m-1) are operated by the output given from the said matcher plus the AND output between the end signal 1 and the overflow signal 2 of the counter 11. In such way, both the matcher and the end signal are utilized, and accordingly the malfunction due to the mischief or the misoperation can be prevented. |
