Abstract

PURPOSE:To improve the reproducing function of a cassette tape recorder by reproducing alternately the music of different cassette tapes by means of two mechanisms which can reverse the tape drive. CONSTITUTION:A variable M is set at initial value when an alternate reproduction switch 4 is kept off. When the switch 4 is turned on a mechanism 2 is put under a reproduction mode. Then the drive of the mechanism 2 is reversed when a tape reaches its termination to maintain the reproduction mode. Then the M is changed to 1 when a music interval detecting part 21 detects a music interval. Thus the mechanism 2 is stopped and a mechanism 3 starts a reproducing action. If the tape termination is detected under such conditions, the driving direction of the mechanism 3 is reversed to keep the reproducing mode. When a music interval is detected, the M is set at 0 and the mechanism 2 starts a reproducing action. Hereafter mechanisms 2 and 3 repeat the reproducing actions alternately in the same way.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This starter #J has a first cassette tape that can stop and rotate and reverse the running of the cassette tape. This invention relates to a cassette tape recorder that uses the second mechanism to alternately produce music from two different types of cassette tapes.

Conventional configuration and its problems Devices equipped with two mechanisms for recording have been known, but in many of them, the first mechanism is for recording and playback, and the second mechanism is for playback only. configured,
Intended for editing and dubbing cassette tapes, etc.
In producing a cassette tape, one mechanism is used (+iii) The function is no different from the function of the L device, and the function is simply to play one cassette to the end, so two mechanisms are fully utilized. It wasn't.

OBJECT OF THE INVENTION The present invention is a tape recorder equipped with two mechanisms capable of reversing tape running, and an object of the present invention is to improve the function in cassette playback by alternately playing back songs on two different cassette tapes. shall be.

Structure of the Invention The device of the present invention has a first reversible running cassette tape.
．． a second mechanism, a control unit that controls each mechanism, and a signal detection unit that detects the presence or absence of a gap between songs on the cassette tape that is being played when each mechanism is in a playback state, and outputs a command thereof to the control unit. when the first mechanism detects the interval between tracks of the cassette tape being played back, the control section stops the first mechanism, starts the second mechanism, and When the second mechanism detects the interval between songs on the cassette tape being played, the second mechanism stops running and the first mechanism returns to the playing state, as described above. It was possible to alternately play one song at a time from a cassette tape.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a front view of a cassette tape recorder according to an embodiment of the present invention. Reference numeral 1 denotes a cassette tape recorder main body, which includes a first mechanism section 2 and a second mechanism section 3. Reference numeral 4 designates an alternate playback operation button for performing the operations of the present invention.

Furthermore, the operation buttons 6 to 10, 11 to 16Ii, the first and second
These are the operation buttons that operate the mechanism of the recording and recording, respectively.
It is configured so that operations such as fast forwarding, rewinding, rewinding, playback, stop, and reversal of running can be performed.

FIG. 2 is a block diagram of main parts of this embodiment.

17 is the first mechanism section 2. The control of the second mechanism section 3 and the control of the first mechanism section 3, respectively. The first mechanism causes the second mechanism to operate. a second operation section, the above-mentioned alternate playback operation button 4;
This is a control section configured to read input from a song interval detection section 21, etc., which will be described later. Further, 2o is an amplifier, and 2o is an amplifier. The output signal from the head (not shown) provided in the second mechanism is outputted to the output terminal 201L of the input L-1 amplifier, and the signal is also outputted to the song interval detection section 21. There is. The song interval detection section 21 is configured to output a pulse indicating a song interval to an output terminal 21 & connected to the control section 17 when the signal from the amplification section disappears for a preset time or more. .

Next, the operation of this embodiment will be explained based on flowchart 1 in FIG. It is assumed that 70-wire in FIG. 3 is a part of the control section 17, and is composed of a microcomputer.

If the alternate playback switch 4 is now off, the flow of the flowchart in FIG. Output 42 is obtained from step 31. In this case, the variable M is always set to the initial value O. .

When the alternate playback switch 4 is turned on, step 3
1.32 and the first mechanism enters the regeneration state. After that, if the end of the tape or the gap between songs is not detected, step 3
3, 34, 35 and so on. Here, when the tape reaches the end, the process moves from step 34 to step 37, and the movement of the mechanism currently running (in this case, the first mechanism section) is reversed and the reproduction state continues.

Next, when the song interval detection unit 21 detects a song interval, the operation starts from step 35 to step 38. Via step 39 the variable M becomes 1, and thus through steps 31.32 we reach step 36 in which the first mechanism stops t1= and the second mechanism starts regeneration. If the end of the tape is detected in this state, proceed to step 34 as described above.
37, the tape running direction of the second mechanism is reversed, and the raw state continues. When a song interval is detected, the operation proceeds through steps 35, 38, and 40, the variable M is set to 0 again, and the second mechanism is stopped at step 32.33, and the first mechanism starts the 111 raw operation again. Start. Thereafter, the first and second mechanisms operate in a similar manner to alternately repeat reproduction.

Effects of the Invention By providing two mechanisms capable of reversing tape running, the present invention can alternately play one song at a time from different cassette tapes attached to each mechanism, and can play six different types of songs. If it is possible to listen in a mixed state, the two mechanisms can be fully utilized in the playback state, and the functions of the tape recorder can be enhanced, and the effect is unique.

Claims (2)

[Claims] (1) A first and second mechanism that can run the cassette tape in forward and reverse directions, a control section that controls these mechanisms, and a detection mechanism that detects the presence or absence of a gap between songs on the cassette tape during playback. When the first mechanism is put into the playback state by the control part and the song interval is detected by the detection part, the second mechanism automatically shifts to the playback state. When the interval between the songs being played is detected, the first mechanism is put into the playing state again, and from then on, the songs on the tapes installed in the first mechanism and the second mechanism are alternately played. A cassette tape recorder that plays back individual pieces. (2) When the end of the tape is detected in one of the mechanisms, the mechanism is automatically reversed to enter the playback state.
