FIG. 1 is a block diagram of a magnetic recording / reproducing apparatus according to an embodiment of the present invention. Reference numeral 4 is a video tape erasure prevention detection switch, and 5 is a device number setting switch.
The same numbers are attached to the same elements as the conventional example.

The relationship and operation of each component will be described with reference to the drawings. Similarly to the conventional example, the control command from the remote controller control unit 1 is input to the VTR control unit through the remote controller receiving unit 2 and the VTR performs the operation according to the command, and at the same time, the command output of the remote controller control unit 1 is output from the control signal output terminal 9. It is output to the outside. During the reproduction operation, the reproduction signal is output to the output terminal 11 by the operation of the video and audio circuits,
13 is output, and during the recording operation, the input terminals 10 and 12
Input signal from is recorded on tape and at the same time output terminal 1
The direct through output signals are output from 1 and 13. The erroneous erasure prevention switch 4 is turned on when the torn tape cassette is inserted, and when a recording system command (recording, post-recording, insert, etc.) is input from the remote controller at this time,
The VTR goes into the playback mode without recording.

In this embodiment, in order to simplify the structure,
Although the operation setting at the time of inputting the recording system command is switched by the erroneous erasure prevention switch, a new setting switch may be provided.

The device number code setting switch will be described. Consists of 2 switches (2 bits), maximum 4
Street combinations are possible. More settings can be made by increasing the number of switches. When sending a VTR control signal from the remote controller, the device number code is sent before the command. (In this case, 2-bit data) On the VTR side, the command is recognized by matching the device number code sent with the setting switch. For example, switch 5 5-1
Is off 5-2 is "0" when 5-2 is off, 5-1 is on 5-
When 2 is off "1", 5-1 is off 5-2 is on "2", 5-1 is on 5-2 When "on"
When defined as “3”, data is transmitted from the remote controller in the order of device number code 0 to 3, command.
