PURPOSE:To attain an effective remote controller in use for a video tape recorder incorporated with a camera, by using the remote controller as both an optical system and a connection system. CONSTITUTION:A photocoupler circuit comprising an LED9 and a photo diode 10 and a wire circuit comprising an interconnection cord 20 connected between jacks are provided together between a transmitter 1 and a receiver 2 constituting the remote controller. In inserting the interconnection cord 20 to the jack 3 for the remote control operation with the wire circuit, the LED9 and the photo diode 10 in the transmitter 1 and the receiver 2 are controlled so as to be inoperative with a switch in the jack 3. The use of the wire circuit eliminates the trouble of external disturbance due to a wireless remote controller at the video recording of the camera of the video tape recorder incorporated with camera, allowing to save power consumed in the optical system. The use of the photocoupler circuit is effective in using said video tape recorder as the stationary type. |
