In FIGS. 1 and 2, the same parts as in FIG. 4 are designated by the same reference numerals.

In FIG. 1, l is VTrt, which is an embodiment of the present invention.
The difference from FIG. 4, which shows the conventional VTR, is that the monitor output terminal (video output terminal + 38.audio output terminal 13b) and the signal output to the monitor output terminal are output to the VTrt output terminal 12a, 12b or the output of the television tuner circuit 2 are provided. switch 2
4 converts the signal output to the antenna output terminal 11 into the signal input to the antenna input terminal IO or the TV modulation circuit 3
The output signal is interlocked with a switch 21 that switches to the output signal.

In addition, the following switches 22a and 22b1 switch 23a
and 23b are collectively referred to as the switch 22 and the switch 23, respectively. Further, each terminal 12a and 12b, 13a and 13b, 14a and 14b will be hereinafter collectively referred to as terminal 12, 13.14, respectively.

FIG. 2 is an external view of the VTR shown in FIG. 1. As shown in FIG. 2, in addition to the conventional VTR control switches 20, 22, and 23, a new monitor output terminal is provided on the front panel of the VTRI.
A switch 24 is provided for switching the output to 3.

The operation of VTl'tI will be explained with reference to FIGS. 1 and 2. Note that the first monitor TV is
It is assumed that a second monitor television is connected to the R output terminal 12 and the monitor output terminal X3.

First, when it is desired to record external human power on a videotape, the switch 22 is switched to the external side, and the recording/reproducing circuit 4 records the video. Also, when you want to record TV broadcast signals on videotape, switch the Sui-Sochi 22 to the tuner side,
It is recorded in the recording/reproducing circuit 4.

Next, if you want to monitor the VTR playback signal using the first monitor television, switch the switch 23 to the VTit side. Further, when it is desired to monitor the signal input to the external input terminal 14 using the first monitor television, the switch 23 can be switched to the external side and the switch 22 can be switched to the external side. Furthermore, when it is desired to monitor a television broadcast signal using the first monitor television, the switch 23 is switched to the external side and the switch 22 is switched to the tuner side.

Next, if you want to monitor the TV broadcast signal using the second monitor TV, you can do so by switching the switch 24 to the TV side, and if you want to monitor the same signal as the first monitor TV, you can switch the switch 24 to the VTR side. You can switch to and monitor.

As described above, by providing the monitor output terminal 13 and the switch 24, a second monitor TV different from the first monitor TV can be connected to the monitor output terminal 13, and the same TV monitor as the first monitor TV can be connected to the monitor output terminal 13. You can monitor the signal or TV broadcast signal.

In the above embodiment, the switch 21 and the switch 24
Although these are interlocked, they may not be interlocked, in which case it is necessary to provide one new switch on the front operation section of the VTR 1 shown in FIG.

This is a diagram. The circuit configuration in FIG. 3 is the same as that in FIG. 1, and in FIG. 3, the VTR 1 is separated into a recording/reproducing section 1a and a television signal modulation/demodulating section 1b, and a connection terminal 5a is connected to the recording/reproducing section Ia to connect them. Also, a connection terminal 51+ is provided in the television signal modulation/demodulation section lb, and a cable 6 connects each connection terminal 5a and 5b.

By separating the television signal modulation/demodulation section 1b in this manner, there is an advantage that the recording/reproducing section 1a, which is the main body of the V T RI, is small and lightweight, making it easier to carry. Furthermore, the television signal modulation section 1b can operate independently compared to the conventional system, and can connect a monitor television and monitor television broadcast signals.
