ABSTRACT:
A light transmitting member is operatively fitted in a remote control light receiving unit for projection from and sinking in a VTR body. A power supply circuit for a light sensor is established when the remote control light receiving unit projects from the VTR body and an optical signal from a remote control device is detected by the light sensor, and the power supply circuit for the light sensor is interrupted when the remote control light receiving unit sinks in the VTR body. Further, the light transmitting member is adapted to cooperate with a locking/unlocking mechanism provided at its lower end portion to set up a reciprocating motion such that the remote control light receiving unit projects from and sinks in the VTR body. With the described arrangement, wasteful power consumption is cut and it is achieved for the remote control light receiving unit not to take in external noise by a simple operation of pushing the rod member in the VTR body when the remote control device is not used and, thus, effect of external noise is minimized.
