DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention monitors the playback signal of a material tape output from a playback player using a monitor receiver, and edits and records the tape at a predetermined position on the inserted editing tape of a recording/playback machine. The present invention relates to an electronic editing device configured to.

BACKGROUND OF THE INVENTION FIG. 2 shows a configuration diagram of an example of a conventional device. As shown in the figure, playback 1 (player) 1. Recording/playback machine (recorder) 2
．． The monitor receivers 3 are connected to each other, and generally the recorder 2
The edited tape to be inserted is monitored by the monitor receiver 3, the editing start point (IN point) and editing end point (OUT point) are specified and registered in the CPU of the recorder 2.
If there is an EE monitor switch, then turn on the EE monitor switch and switch from the recorder 2 monitor to the player 1.
The player 1's material tape is monitored by the monitor receiver 3, and its IN point is designated and registered in the CPU of the player 1 (the OUT point is not designated for the player 1). During insert recording, the IN point of the recorder 2 and the IN point of the player 1 are synchronized, and insert recording is performed from the IN point to the OUT point of the tape to be edited. In addition,
Switching from the monitor of the recorder 2 to the monitor of the player 1 is called an EE monitor, and is used in a system having only one monitor receiver and device.

In this case, after specifying each edit point (IN point, OUT point) in the above order on recorder 2 and player 1, the output of player 1 becomes a still image playback, but in a system without an EE monitor switch, , first recorder 2's I
If the N point and the OUT point are specified, the IN point of player 1 cannot be specified, and in such a system, the IN point of player 1 is specified first.

On the other hand, conventionally, as shown in FIG. 3, there is a system provided with a controller 4 that can remotely control the operation of each of the 1° recorder 2. The controller 4 is provided with an EE monitor switch (record FE button), and after specifying the IN and OUT points of the tape to be edited on the recorder 2, turn on the FE monitor switch to monitor the material tape on the player 1. Next, while looking at the monitor of player 1, specify the IN point of the material tape, and turn off the EE monitor switch. In this way, both the player 1 and the recorder 2 can be controlled by remote control.

Problems to be Solved by the Invention The system shown in FIG.
Specify the edit point on the tape to be edited with , turn on the EE monitor switch on recorder 2 to monitor the source tape, operate player 1 to specify the edit point on the source tape, and turn off the EE monitor switch on recorder 2 again. The problem was that the procedure was complicated and time-consuming. or,
In the case shown in FIG. 2, after turning on the EE monitor switch on recorder 2 and monitoring the material tape, even if you perform operations such as play on recorder 2, the edited tape on recorder 2 is not monitored. For the operator, although the recorder 2 was operated, the tape to be edited was not played back, which caused confusion in the operation, and there was a problem that it was not easy to use.

On the other hand, the system shown in FIG. 3 has the problem that the controller 4 must be newly provided, which increases the size of the system.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic editing device that is easy to operate, can be operated in a short time, is easy to operate, is convenient to use, and can be constructed in a small size.

Means for Solving the Problems The present invention provides a recording/playback device with a switch function for switching from monitoring the tape to be edited to monitoring the playback of the material tape of the playback device, and also provides the recording/playback device with a switch function that switches the monitor of the tape to be edited to the playback monitor of the material tape of the playback device. The configuration is provided with a control means that performs I-control so that the recording/reproducing apparatus does not operate even if various operations are performed on the recording/reproducing apparatus while the recording/reproducing apparatus is in use.

When the function switch i function is turned on, the control means is switched to the playback device control side, and while it is on, the recording and playback device will not operate even if you perform mode operations such as play or stop on the recording and playback device side. , without causing any operational confusion. or,
While the switch function is on, the playback device is configured to operate according to various operations performed on the recording/playback device side, and as a result, various operations can be controlled only from the recording/playback device vi side, and operations can be performed. It is simple, and furthermore, since the material tape of the player can be monitored only while the switch function is on, the operation will not be confused even if there is no EE monitor display.

Embodiment FIG. 1 shows a block diagram of an embodiment of the apparatus of the present invention. In the figure, numeral 5 denotes a recorder, and an EE monitor switch 6 and an operation switch 7 are provided on the panel. The operation switch 7 is a mode switch for play, stop, insert editing start, etc.

It consists of a speed switch for variably setting the tape speed, an edit point designation switch for designating the edit point, etc. 8 is a switch circuit which switches between a recording monitor signal and a reproduction signal and supplies the signal to the monitor receiver 3;
9 is an encoder that encodes the output of the operation switch 7; 10 is a switch circuit; the EE monitor switch 6;
This is a switch that switches the output of the encoder 9 to the recorder 5 main body side and the player 11 side based on the output. Reference numeral 12 denotes a control circuit that controls the main body of the recorder 5 to be set in a predetermined state in accordance with the operation of the operation switch 7.

Next, the operation of the present invention will be explained. First of all, normal time (E
When the E monitor switch 6 is off), the switch circuit 10 is switched to the terminal R (main body) side, and switch information operated by the operation switch 7 is supplied to the control circuit 12. For example, when a play operation is performed to monitor the tape to be edited, the control circuit 12 outputs an L level E! The IJ10 signal is output and supplied to the switch circuit 8 via the OR gate 13, and the switch 8 is connected to the terminal PB side. on the other hand,
A control signal is output from the control circuit 12 by the play operation of the operation switch 7, and the playback circuit 14 is activated, and the edited tape playback signal from the playback circuit 14 is outputted via the switch circuit 8 and is monitored! & Monitored by machine 3.

Here, when an edit point (IN point, OUT point) on the tape to be edited is specified using the operation switch 7, switch information is supplied to the control circuit 12, and the edit point is registered there.

Note that when the EE monitor switch 6 is turned off and a recording operation is performed using the operation switch 7 in addition to insert editing, the E E 1lill tit signal from the control circuit 12 becomes H level, and the switch circuit 8 is switched to the terminal EE side. connected to. As a result, a signal from an external source such as a tuner is supplied to the recording circuit 15 and recorded on the tape of the recorder 5, while being transmitted to the monitor receiver 3.

Next, when performing EE monitoring, the EE monitor switch 6 is turned on. As a result, the switch circuit 8 is connected to the terminal E.
At the same time, the switch circuit 10 is switched to the terminal 5WAP side, and when a play operation is performed with the operation switch 7, the switch information is transferred to the switch circuit 10. The signal is outputted from the 5WAP output terminal 17 via the buffer 16 and supplied to the 5WAP input terminal 18 of the player 11, and the playback signal of the material tape from the player 11 is monitored by the monitor receiver 3 via the switch circuit 8. In this case, even if the switch circuit 8 is connected to the terminal PB side while the recorder 5 is playing, the switch circuit 8 will be connected to the terminal EE side when the EE monitor switch 6 is turned on, and the output of the player 11 will be changed by the play operation. can be monitored.

The EE monitor switch 6 is configured to be turned on only while it is pressed, and turned off as soon as it is released. Therefore, while pressing the EE monitor switch 6, search for and specify the playback of the material tape on the monitor receiver 3 (while monitoring number i, operate the operation switch 7 to edit the material tape IN point).
The editing point is registered in the control circuit (not shown) of the player 11. In this way, since the editing point of the player 11 can be specified on the recorder 5 side, the operation is easier than in the conventional example shown in FIG. Since the terminal 5 is connected to the WAP side, even if you accidentally operate the operation switch 7 to operate the recorder 5, there will be no effect on the edited tape of the recorder 5, and you can operate it as in the conventional example. without causing any confusion.

Also, since the EE monitor switch 6 is configured to be on only while it is pressed, there is no EE monitor display (but currently the EE monitor is not displayed).
It can be easily determined whether or not the image is being monitored, and it can also be easily determined that the image currently being monitored is the image being monitored by the player 1.

In this way, the player 11 has an IN point, and the recorder 5 has an IN point.
After registering the point and the 0tJT point, turn off the EE monitor switch 6 and perform a start operation using the operation switch 7. As a result, $11111 circuit 12 to player 11
A control signal is supplied to the IN point, and both IN points are synchronized.
The contents from the IN point of the material tape are inserted and recorded from the IN point to the OUT point of the tape to be edited. In this case, the switch circuit 8 is connected to the EE side by the start operation, the recording circuit 15 is activated by a control signal from the control circuit 12, and the output of the player 11 is recorded in the recording circuit 15.

Note that the EE monitor switch generally has a function of switching to the player side during playback of the recorder to monitor the player output, but as in this embodiment, the EE monitor switch has the function of switching to the player side during playback of the recorder and monitoring the player output. When the switch circuit 10 is provided, for example, during the recording operation of the recorder 5 (
When the EE monitor switch 6 is turned on by the H level EEfi (according to +1211-8) from the control circuit 12, the player 11 can be operated independently by switching the switch circuit 10 while the EE monitor switch 6 is turned on, further improving usability.

As described in detail, according to the present invention, various operations can be controlled only by operation on the recording/reproducing device side, and the operation is simpler and takes less time than the conventional example. While the playback device is being monitored by turning on the function, the recording and playback device will not operate even if you perform an operation on the recording and playback device side, and there will be no operational confusion like in the conventional case. The player can be monitored only while the function is on, so E
It is easy to use because it can be easily determined that EE monitoring is being performed even without the E monitor display, and furthermore, since no controller is required, the system can be made smaller.
