<p>PURPOSE:To input easily a program picture recording program by setting an input device provided with a light emitting diode to a video tape recorder body and transmitting information from the input device to the recorder body through light. CONSTITUTION:An input device 4 is provided with a light emitting diode 9 and a set mounting confirming photo diode 8, and program picture recording program information is preliminarily stored in the state where the device 4 is detached from the video tape recorder. When this device 4 is set to the recorder body, information is transmitted to a photodiode 11 of a recorder body circuit by flickering of the diode 9, and therefore, an operator can input program picture recording program information within reach. That is, the operator can input program picture recording program information easily in an optional place (for example, a room with no video tape recorders) while watching a program column on a newspaper or the like.</p> |
