If you wish to continue recording, the video camera may be able to control the operation, for example by controlling the pause button on the video camera and disabling it by operating the pause button on the stirrup side of the recording/playback device. Must be changed depending on whether it is connected or not! occurs. Conventionally, the control signal 4 for operating such a control circuit 4 is obtained by converting, for example, a video signal 5 supplied from a plug connected to the camera connector 2 into a synchronizing signal of the video signal black through a detection circuit 5. (by detecting the wave).

ある。FIG. 2 shows the main parts of an embodiment of the video recording and reproducing apparatus according to the present invention, in which a plug (not shown) is connected to the connector 2'.
A switch 7 is provided which operates in conjunction with the connection of the camera plug, and when the camera plug is connected, this switch is operated to generate a control signal 4 for controlling the control circuit 6.

圧となる信号１０を発生させることがてきる。wtsrxt is a physical example of a switch 04 which is switched (when a camera plug is connected) and connects the common terminal COM to the control path 6. LC is a contact point that is connected to itself when the plug is not connected, and C is a contact point that is connected to itself when the plug is connected. For example, use this switch as 11311(a)
By connecting the camera plug as shown above], it is possible to generate a signal 8 that controls the inside of the video recording and reproducing apparatus, which becomes the ground voltage when the camera plug is connected to the connector, and becomes the power supply voltage when it is not connected. In addition, as in No. 311(b), the recording/reproducing device connects the signal 9 which becomes the power supply voltage during reproduction to the power source, respectively) during reproduction or the camera [5! It is possible to generate a signal 10 which becomes the power supply voltage.
この信号１０は例えばモニタ用のテレビ受像機を動作さ
せるテレビ制御信号として利用することもできる。This signal 10 can also be used, for example, as a television control signal for operating a television receiver for monitoring.

、低コストとなる。As described above, according to the present invention, a control signal is generated using a connector to which a camera plug is connected and which is optionally equipped with a switch. A detection circuit for detecting camera Prada OII is not required, and the circuit configuration is simplified, resulting in low cost.
