Remote control receiver

Abstract

Abstract PURPOSE:To attain direction control with one transmission by providing plural diodes and a means applying comparison arithmetic operation processing to a detected signal level so as to discriminate the arrival direction of the signal to the receiver. CONSTITUTION:The receiver is provided with plural photodiodes 2A-2C arranged respectively in plural directions, a means detecting a reception signal level of control data received by the photodiodes 2A-2C, that is, an amplifier 4, a band pass filter 6, a detector 7 and an A/D converter 8 or the like and also a means used to compare and arithmetic-operate the detected signal level to discriminate the incoming direction of the signal, that is, a microcomputer 9. Thus, the direction of the object device is changed in a desired direction by one transmission by using the usual control data other than the direction control. Thus, the direction control is implemented by one transmission.
