Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tape recorder dubbing device for dubbing from a player to a tape recorder, which is equipped with at least a cue playback means for cueing information.

[Prior art] When dubbing a program source from a compact disc player or the like to a tape recorder,
Select the input source to the tape recorder using the recording input selector, put the tape recorder in recording standby (pause) state, put the disk player into playback state, and after adjusting the recording level, equalizer, bias, etc., start recording with the tape recorder. The standby (pause) state is canceled and the tape recorder is put into the recording state, and the disk player in the playback state is played back from the beginning of the information (program song) being played back using the cue playback means, and the information (program song) on the disk player is played back from the beginning. A common method was to dub the program songs from the beginning onto a tape recorder.

[Problem to be solved by the invention] By the way, in such a dubbing device for a tape recorder, when dubbing, it is necessary to cancel the recording standby (pause) state of the tape recorder and bring it into the recording state, and to change the playback state. The operation was troublesome because the two operations of reproducing the information (program song) being reproduced from the beginning of the disc player using the cue reproducing means had to be performed separately and at the right timing. Also, since each operation is performed individually, depending on the timing of each operation,
For example, if the cue playback means of the disk player is operated sufficiently before the operation to cancel the recording standby (pause) state of the tape recorder, that is, the disk player enters the playback state before the tape recorder enters the recording state. This caused problems such as the beginning of the disc player's information (program song) being omitted in the dubbing. Therefore, this invention solves these conventional problems with a simple structure.

[Technical means for solving the problem] In other words, in order to solve the above-mentioned problem, in this invention, a player equipped with a cue playback means for at least cueing information can at least detect the recording state. Recording standby (pause) in the recording state
control means for operating cue playback means of the player in response to an operation for bringing the tape recorder from a recording standby (pause) state to a recording state; and the control means is operable at least when the player is in a playback state and is selected as a recording input source for the tape recorder, and the tape recorder is in a recording standby (pause) state. By configuring the tape recorder, the information being played back on the player can be played back from the beginning and dubbed into the tape recorder through the control means simply by canceling the recording standby (pause) state of the tape recorder and bringing it into the recording state. This is what I did.

They are connected to the O-PLAY terminal of the computer 27 and to the output circuit 10a of the function detection circuit 10, respectively. In addition, the output of the AND circuit AND30 is sent to the control microcomputer 2 on the disk player 2 side.
It is connected to the back skip button (B-SKIP) 27g of No.7.

The tape recorder dubbing apparatus of the present invention has the above-mentioned structure, and its operation will be explained next.

Now, let us consider the case where the contents reproduced by the disk player 2 are recorded by the tape recorder 1.

First, the disk player 2 is selected as a program source supplied to the recording input terminal RIN of the tape recorder 1 by the function switch FS. As a result, the output terminal 10a of the function detection circuit 10 becomes high level.

Next, by operating the record button 8a and pause button 8F of the tape recorder 1, a control signal is output from the control microcomputer 9, and the recording/playback switch 7 is switched to the recording system 5 side, and the tape drive system is switched. Make the recording pause state. Therefore, both the O-REC terminal and the O-PAUSE terminal of the control microcomputer 9 become high level.

Note that when the O-PAUSE terminal becomes high level, its rising edge is inverted by the NOT circuit NOT, and a negative pulse differentiated by the differentiating circuit 30 is applied to the gate of the AND circuit AND.
Since it is a negative pulse, there is no change in the output of the AND circuit AND.

On the other hand, by operating the playback button 28a of the disc player 2, a playback command is sent to the control microcomputer 27, and the disc player 2
is in playback state. In this state, the O-PLAY terminal of the control microcomputer 27 goes high, indicating that the disc player is in the playback mode.

That is, the tape recorder 1 is set to a recording pause state, the disk player is set to a playback state, and the recording level, equalizer,
Perform bias adjustment, etc. Since these adjustment operations are well known, their explanation will be omitted.

As mentioned above, in this state, the control microcomputer 9 of the tape recorder 1 is
Although the REC terminal, the O-PLAY terminal of the microcomputer 29 for controlling the disk player 2, and the output terminal 10a of the function detection circuit 10 are at a high level, only the output of the differentiating circuit 30 is at a low level.

When the tape recorder 1 is released from the recording pause state to start dubbing in this state, the O-PAUSE terminal of the control microcomputer 9 changes from high level to low level, so this change
AND via NOT circuit NOT and differentiator circuit 30
This will be applied as a high level signal to the gate of the circuit AND. Therefore, all the gates of the AND circuit AND become high level, and the output side, that is, the microcomputer 2 for controlling the disk player 2.
A high level signal is applied to the back skip terminal 27g of No.7.

This causes the disk player 2 to operate the back skip button 28g, return to the beginning of the program song being played, and play the program song again from the beginning. This back-skipping operation is performed instantaneously, and thereafter the content reproduced by the disk player 2 can be dubbed to the tape recorder 1 side.

In this embodiment, a compact disc player was used as an example of the player, but the present invention can be implemented in any player having cue playback means.
