As shown in FIG. 3 (a), when the power supply Vcc is applied and the power supply monitoring IC 40 detects the rising of the power supply voltage, a negative detection pulse is output from the power supply monitoring IC 40 and the F / F
The circuit 42 is cleared and the Q output terminal becomes high level and the output terminal becomes low level. As a result, the standby command, which is the Q output signal of the F / F circuit 42, becomes high level as shown in FIG. 3 (c). The recording command connected to the output terminal of the F / F circuit 42 is delayed by the delay time t by the delay circuit 44 and becomes low level as shown in FIG. 3 (d).
This delay circuit 44 is provided so that the recording command always changes after the standby command. Therefore, the standby command has priority over the recording command. At this time, the high level standby command causes the VTR 10 to enter a pause period as shown in FIG. 3 (e). This state continues until a remote signal comes from the video processing device 16.

Remote signal (negative pulse) as shown in Fig. 3 (b)
Is input from the video processor 16 to the adapter 14, the F / F
The output state of the circuit 42 is inverted, and as shown in FIG.

The output state of the circuit 42 is inverted, the recording command and the standby command are alternately set to the high level, and the operation mode of the VTR 10 is alternately set to the recording mode and the pause mode, as shown in FIG. 3 (e).

As shown in FIG. 3 (e), the supply of the power supply Vcc is stopped,
Even when the power supply monitoring IC 40 detects the fall of the power supply voltage,
The F / F circuit 42 is cleared and the Q output terminal becomes high level and the output terminal becomes low level. This is to stop the recording operation of the VTR 12 when the operation of the video processing device (remote control device) 16 is stopped.

As described above, according to the first embodiment, the VT is generated by the remote pulse generated from the remote control device.
The operation mode of R can be switched to the recording mode and the recording still mode alternately. The operation command designating this operation mode can be continuously supplied to the VTR during each operation period.

FIG. 4 is a detailed circuit diagram of the second embodiment of the adapter 14. The first embodiment describes an adapter for controlling a VTR of the type in which operating commands must be supplied during each operating mode. On the other hand, in the second embodiment, an adapter for controlling the VTR of the type in which the operation command needs to be supplied only when switching between the operation modes will be described. As in the case of the first embodiment, the power supply Vcc and the remote signal are supplied from the video processing device 16 to the adapter 14, and the mode signal is supplied from the adapter 14 to the video processing device 16. Recording head activation signal from VTR 10 to adapter 14 Tape running signal Pause signal A signal is supplied and a tape quiesce command is sent from adapter 14 to VTR 10.

The tape quiescent command and the tape running command are negative pulses generated only during a predetermined period when the tape is quiescent and when the tape running is started.

The remote signal supplied to the adapter 14 is the AND gate 60, 6
2 is input to the first input terminal. AND gate 60 output is AND
It is supplied to the first input terminal of the gate 61. The output signal of the power supply monitoring IC 40 similar to that of the first embodiment is supplied to the second input terminal of the AND gate 61. The output of the AND gate 61 is supplied to the VTR 10 as a tape freeze command. The output of the AND gate 62 is supplied to the VTR 10 as a tape running command. The recording head operating signal and the tape running signal supplied from the VTR 10 to the adapter 14 are input to the AND gate 64. The output of the AND gate 64 is input to the first input terminals of the AND gates 66 and 70. The pause signal is supplied to the second input terminal of the AND gate 66 via the inverter 68, and the pause signal itself is supplied to the second input terminal of the AND gate 70.

The operation of the adapter 14 according to the second embodiment shown in FIG. 4 will be described with reference to FIGS. 5 (a) to (h). Fig. 5 (a)
When the power supply Vcc is applied and the power supply monitoring IC 40 detects the rise of the power supply voltage as shown in Fig. 5, the negative pulse signal which is this output passes through the AND gate 61, and the tape is stopped as shown in Fig. 5 (c). A command (negative pulse) is supplied to VTR12. As a result, the recording head operating signal from the VTR 12 becomes negative as shown in FIG. 5 (f), and the mode signal representing the pause mode is output from the AND gate 70 as shown in FIG. 5 (e).

At this time, the pause signal is at the low level as shown in FIG. 5 (h) and the output of the AND gate 64 is at the low level, so the output of the AND gate 66 is at the high level. Therefore, when a remote signal is generated from the video processing device 16 as shown in FIG. 5 (b), this negative pulse signal is output from the AND gate 62, and the tape running command as shown in FIG. 5 (d). Is generated. As a result, the VTR 12 becomes a recording mote as shown in FIG. 5 (e), and the mode signal becomes low level as shown in FIG. 5 (e). As shown in FIGS. 5 (g) and 5 (h), the tape running signal and the pause signal become low level and high level, respectively.

When the following remote signal is supplied from the video processing device 16,
At this time, since the output of the AND gate 70 is at the low level, the negative pulse remote signal passes through the AND gate 60 and
As shown in Figure (c), a negative pulse tape rest command is generated. Similarly, every time a remote signal arrives, AN
The D gates 60 and 62 are alternately conducted, and the tape stop command,
Alternate tape run commands are issued.

As shown in FIG. 5 (a), the supply of the power supply Vcc is stopped,
Even when the power supply monitoring IC 40 detects the fall of the power supply voltage,
A tape quiescent command is output from the AND gate 60 as when the power is turned on, and VT is output when the video processing device 16 stops operating.
The recording operation of R12 also stops.

As described above, according to the second embodiment, the VT is generated by the remote pulse generated from the remote control device.
The operation mode of R can be switched to the recording mode and the recording still mode alternately. The operation command that specifies this operation mode is VT only when switching each operation mode.
Can be supplied to R.

It is needless to say that the present invention is not limited to the above-described embodiment, and the specific configuration of the adapter is changed according to the control signal form of the VTR.

[Effects of the Invention] As described above, according to the present invention, the remote pulse from the remote control device becomes the controlled target VT.
The versatility of the remote control device can be improved by connecting an adapter that converts the signal into a signal according to the R control signal form.
