PURPOSE:To prevent occurrence of malfunction or inoperation of a remote controller by regulating the operation of a remove control photodetecting section with a regulation means or regulating a signal from a remote control section when the installation of controller is detected by a detection means. CONSTITUTION:A controller installation sensor 5 detects that a controller 3 is loaded onto a controller placing base 4 to interrupt the circuit of the remote control photodetector 2 in the earth side mechanically. Thus, the operation of the remote control photodetector 2 is regulated to stop its operation. When the operation of the remote control photodetector 2 is stopped, even if a strong external disturbance light is made incident therein, the signal from a photodetector 1 for fixed loading is not disturbed. Thus, normal operation of an equipment main body X is guaranteed by making a control light from the controller 3 to the fixed loading photodetector 1. |
