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.

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide an arrangement for a VTR, without increasing size of the body of the VTR and its cost, in which a rod member is allowed to project from the VTR body only when a remote control device is used, whereby a power supply circuit for a light sensor is automatically established so that wasteful power consumption is curtailed, and when the remote control device is not used, the rod member is housed in the VTR body, to thereby prevent the VTR from taking in external noises, by such a simple operation as to push it down so that wasteful power consumption is curtailed.
In order to solve the above mentioned problems, the present invention comprises a remote control light receiving unit operatively arranged for projecting from and sinking in the VTR body and having a light receiving window for receiving an optical signal from an external remote control device to be transmitted to a light sensor and a light transmitting member, which is fitted in the remote control light receiving unit so as to be projected from or housed in the VTR body, and a switch operatively associated with the light transmitting member for establishing a power supply circuit for the light sensor when the remote control light receiving unit projects from the VTR body and interrupting the power supply circuit for the light sensor when the remote control light receiving unit sinks in the VTR body.
The present invention further embraces an arrangement in which the light transmitting member is fitted in the remote control light receiving unit so as to direct the light received by the remote control light receiving unit through the light receiving window to the light sensor.
The remote control light receiving unit, operatively arranged for projecting from and sinking in the VTR body, receives an optical signal from an external remote control device and transmits it to a light sensor.
The remote control light receiving unit, operatively associated with the light transmitting member fitted therein so as to be projected from and housed in the VTR body, establishes the power supply circuit for the light sensor upon its projecting from the VTR body and interrupts the power supply circuit for the light sensor by opening the switch upon its sinking in the VTR body
