Abstract

PURPOSE:To improve remarkably the operability of a tape recorder by stopping automatically the running of the other tape when a shorter tape comes to its end so as to prevent useless tape running in recoding a signal on a recorded tape onto a recording tape with a different length. CONSTITUTION:When the 1st tape 11 comes at firs;t to its end while a reproduced sound on the 1st tape 11 loaded to the 1st tape running section 1 is recorded onto the 2nd tape 22 loaded to the 2nd tape running section 2, the 1st end detection section 3 outputs an [H] signal to OR circuits 52, 63. The OR circuit 52 outputs the [H] signal to the 1st running control section 50, which brings the running mode of the 1st tape running section 1 from [reproduction] to [stop] mode. Further, the OR circuit 63 outputs an [H] signal to the 2nd running control section 60 and the 2nd running control section 60 brings the running mode of the 2nd tape running section 2 from [recording] to [recording pause] mode.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention has a plurality of tape running sections, and the playback sound of a tape mounted on one tape running section is recorded on the tape mounted on the tape running section. It concerns a possible tape recorder.

Conventional Structure and Problems Generally, in a tape recorder having multiple tape running sections, the first tape 11 attached to the first tape running section 1 reaches the end, as shown in the block diagram in FIG. Then, the first end detection section 3 outputs a signal to the first running control section 5 so that the first tape running section 1 stops running. Similarly, when the second tape 22 mounted on the second tape running unit 2 reaches the end, the second end detection unit 4 detects the second running controller 6.
2, the tape running section 2 is not affected. Further, the second end detection section 4 does not affect the first tape running section 1.

As a result, the reproduced sound of the first tape 11 is transferred to the second tape 2.
2, even if the first tape 11 reaches the end,
The second tape 22 continues running until it reaches the end. Similarly, even if the second tape 22 reaches its end, the first tape 1
1 continues running until it reaches the end. That is, if the first tape 11 is shorter than the second tape 22, after the first tape 11 reaches the end, the second tape 22 continues recording without input (number a). However, after recording side A of the first tape 11 onto the second tape 22, side B of the first tape 11 is recorded onto the second tape 22.
If you want to continue recording on the same side of the tape, use the second tape 22.
There is a disadvantage in that it is necessary to perform the troublesome work of rewinding the tape 11 and searching for the place where side A of the first tape 11 ends. Further, if the first tape 11 is longer than the second tape 22, after the second tape 22 reaches the end, the first tape 11
The tape 11 continues to be played back without being recorded onto the second tape 22. Therefore, the playback signal of the first tape 11 is recorded on the A side of the second tape 22, and after the A side of the second tape 22 reaches the end, the playback signal of the first tape 11 is continuously recorded. When recording on the B side of the second tape 22, first check at which position on the first tape 11 the A side of the second tape 22 has reached its end by rewinding the second tape 22. This method has the disadvantage that it requires the troublesome work of searching for the position of the first tape 11 corresponding to that position.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional problems. When recording a signal from a recorded tape onto a recording tape having a length different from the already recorded tape, the shorter tape ends. When reaching this point, the running of the other tape is automatically stopped.
The purpose is to prevent wasteful tape running and greatly improve the operability of a tape recorder.

Structure of the Invention The present invention provides a first tape running section capable of reproducing a mounted tape, a first end detection section detecting the end of the tape, and a first tape running section controlling the running of the tape running section. a running control section, a second tape running section capable of recording on the mounted tape, a second end detection section detecting the end of the tape, and a second running control section controlling the running of the tape running section. The tape recorder is equipped with a first end detecting section and a second end detecting section while recording the playback sound of the tape mounted on the first tape running section onto the tape mounted on the second tape running section. When at least one end detection part among the detection parts detects the end of the tape attached to each tape running part, the first running control part and the second running control part are controlled to each tape running sound. When recording on a tape with a different length from the original tape, when the shorter tape reaches its end, the running of the two tapes is automatically stopped, improving operability.

The operation of the tape recorder of this embodiment configured as described above will be described below.

While recording the playback sound of the first tape 11 mounted on the first tape running section 1 onto the second tape 22 mounted on the second tape running section 2, the first tape 11 first reaches its end. When the rHJ signal reaches the
is output to the OR circuit 63. When the OR circuit 62 receives the [HJ multiplied signal, it outputs an “H” signal to the first travel control unit 50. When the rHJ signal is input to the stop input terminal, the first running control section 60 controls the first tape running section 1.
Change running from "play" to "stop".

Further, when the rHJ signal is input, the OR circuit 63 inputs the second
The rHJ signal is output to the travel control section 6o.

When the rHJ signal is input to the pause input terminal, the second running control section 60 changes the running of the second tape running section 2 from "recording" to "recording pause." As a result, when the first tape 11 reaches the end, both the first tape running section 1 and the second tape running section 2 stop running.

Further, when the second tape 22 reaches the end, the second end detection section 4 outputs the [HJ times signal to the OR circuit 62 and the OR circuit 52. When the OR circuit 62 receives the rI(J signal, it outputs the rHJ signal to the second travel control section 60.
When the rHJ signal is input to the stop input terminal, the running control section 6o changes the running of the second tape running section 2 from "recording" to "stop". Further, the OR circuit 62 is “H”
When the signal is input, the running of the first running section 1 is changed from "playback" to "stop" as described above. As a result, when the second tape 22 reaches the end, both the first tape running section 1 and the second tape running section 2 stop running.

Therefore, when either the first tape 11 or the second tape 22 reaches its end, both the first tape running section 1 and the second tape running section 2 stop running.

As described above, according to this embodiment, at least one of the first end detection section 3 and the second end detection section 4 detects the end of the tape mounted on the respective tape running section. When detected, the first running control section 6o and the second running control section 60 are configured to stop running the tapes attached to their respective tape running sections, so that the first tape 11 cannot be played back. While recording sound on the second tape 22, that is, dubbing, it is possible to obtain the effect of preventing a situation in which, after one tape reaches the end, the other tape continues to run without being dubbed.

In the embodiment shown in FIG. 2, the output signal of the first end detection section 3 is input to the stop input terminal of the first travel control section 5o via an OR circuit 62, and is also input to the stop input terminal of the first travel control section 5o via an OR circuit 63. Since the input is configured to be input to the pause input terminal of the running control unit 6°, when the first end detection unit 3 detects the end of the first tape 11, the first tape running unit 1 In "stop mode", the second tape running section 2
is in "recording pause mode", so the first tape 11
After recording the A side of the first tape 11 onto the second tape 22, it is easy to continue recording the B side of the first tape 11 onto the same side of the second tape 22. .

Furthermore, in the embodiment shown in FIG.
0 to the stop input terminal of the first travel control section 50 via the OR circuit 62, the second termination detection section 4 When the end of the tape 22 is detected, the second
Since both the tape running section 2 and the first tape running section 1 are in the stop mode, during playback of the first tape 11,
When side A of the second tape 22 during recording reaches the end,
It is possible to easily record the continuation of the first tape 11 onto the B side of the second tape 22.

In the embodiment shown in FIG. 2, the output signal of the second end detection section 4 is inputted to the stop input terminal of the first travel control section 6o via the OR circuit 62.
When the operation switch has a pause switch and the first travel control section has a pause input terminal, the output signal of the second termination detection section 4 is connected to the output signal of the pause switch through an OR circuit with the output signal of the pause switch. , it goes without saying that the above-mentioned effects can be obtained even in a tape recorder configured so that input is input to the pause input terminal of the first travel control section, and that this is included in the present invention.

In addition, when the first travel control section and the second travel control section are configured with a microcomputer, the output signals of the first termination detection section and the second termination detection section are input directly to the microcomputer, and the internal It goes without saying that the present invention also includes a tape recorder configured so that the above-described operation can be obtained on the memory of the computer.

Effects of the Invention As described above, according to the present invention, when using the first tape,
At least one end detection section among the first tape running section, a first end detection section that detects the end of the tape mounted on the second tape running section, and a second end detection section detects the end of the tape mounted on the second tape running section. When the end of the tape mounted on the tape section is detected, the first running control section and the second running control section control the running of the first tape running section and the second tape running section. By configuring the tape attached to the running section to stop running, when recording on a recording tape of a different length from the already recorded tape, when the shorter tape reaches its end, the running of the other tape stops. Since the tape automatically stops, unnecessary running of the tape can be prevented, and an excellent tape recorder can be realized which improves the operability of tape dubbing.
