Abstract

PURPOSE:To make the operation easy, by so constituting that the 2nd cassette mechanism is also brought to the temporary stop by interlocking with the 1st cassette mechanism when it is brought to the temporary stop. CONSTITUTION:When the 1st cassette mechanism 1 is brought into the temporary stop state, a switch S3 which is turned in interlocking with the state change is provided and a driving circuit of a cassette tape driving motor provided with the 2nd cassette mechanism 2 is controlled so that the 2nd cassette mechanism is brought into the temporary stop at the same time when the 1st cassette mechanism is brought into the temporary stop. Thus, through the operation of the temporary stop button provided with the mechanism 1, the 1st and 2nd cassette mechanisms can arbitrarily be brought into the temporary stop. Thus, the operation can be made easy.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the first aspect. A tape recorder having a second two-cassette mechanism records the signal reproduced by the first cassette mechanism onto a cassette tape loaded in the second cassette mechanism by the second cassette mechanism. The object of the present invention is to provide an excellent tape recorder that is particularly effective in this case.

Generally the first. Tape recorders with a second two-cassette mechanism are known, but all of these types only have a separate pause button on each cassette mechanism 2-j-'. be. Therefore, this type of tape recorder is capable of recording and releasing recording signals from a first cassette tape loaded into a first cassette mechanism onto a second cassette tape loaded into a second cassette mechanism. If you try, try the first step. There was a problem in that it was necessary to simultaneously operate separate playback buttons, record buttons, or pause buttons equipped on the second cassette mechanism to release the paused state at the same time, which was extremely troublesome. .

The present invention aims to eliminate the following two drawbacks of the conventional tape recorder, and to provide an excellent tape recorder that has a simple structure and is easy to operate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The tape recorder of the present invention will be described below with reference to drawings of one embodiment. In the figure, 1 is a first cassette mechanism exclusively for playback, and the first cassette tape loaded into this mechanism 1 is driven by a first motor 3'M, which is installed in the mechanism 1. It is configured as follows. 2 is a second cassette mechanism for both recording and playback, and the second cassette tape loaded into this mechanism 2 is configured to be driven by a second motor M2 installed in the mechanism 2. There is. And Sl is the first
Switches Q+ and Q2, which are turned on when the cassette mechanism 1 is in the playback state, are transistors R,, R,!, which constitute the drive circuit of the motor M1. A resistor, S2 is a switch that is turned on when the second cassette mechanism 2 is in a playback state or a recording state, and Q, 4, and Q5 are motors M.
Q3 is a transistor that is controlled on and off by a switch S3 to be described later, R3 and R4 are resistors, and S3 is a switch that is turned on when the first cassette mechanism 1 is temporarily stopped.

In the embodiment described above, it is assumed that the playback button of the first cassette mechanism 1 is pressed to put the first cassette mechanism 1 into the playback state. In this case, the switch Sl is turned on and the +β power supply is applied to the base and collector of the transistor Q through the resistors R1 and R2, respectively, so that the transistor Q1 is turned on, and at the same time, the transistor Q2 is turned on. Therefore, the motor M1 is driven to run the first cassette tape loaded in the tenth slot mechanism 1 at a constant speed.

Next, it is assumed that the playback button or the recording button of the second cassette mechanism 2 is pressed to put the two sets of second cassette mechanisms 2 into the playback state or the recording state. In this case, the switch S2 is turned on, and the 10B power supply is connected to the base of the transistor Q4 via the resistors R3-R4.

Since the voltage is applied to the collector of transistor Q4. Q5 is turned on, motor M2 is driven, and the 20th cassette mechanism 2
The second cassette tape loaded in the second cassette tape runs at a constant speed.

Now, suppose that the pause button of the first cassette mechanism 1 is pressed to put the first cassette mechanism 1 into a paused state. In this case, since the switch S5 is turned on, the -B power supply is applied to the base of the transistor Q3, and the transistor Q3 is turned on. Therefore, the base potential of the transistor Q4, which had been on until now, drops to the ground potential, and the transistor Q4 and the next stage transistor Q
5 will both turn off. Therefore, the power supply to the motor M2 is stopped, the driving of the motor M2 is stopped, and the second cassette mechanism 2 is also temporarily stopped.

When the pause button of the first cassette mechanism 1 is released and the first cassette mechanism 1 is returned to the playback state, the switch S3 is turned off, so the transistor Qs is turned off again, and the transistor Q4. Qs is turned on, and the second sumo wrestler's throat mechanism 2 returns to the playback state or recording state.

In this way, according to the above embodiment, the tenth cassette mechanism 1 is provided with a switch S3 that is turned on when the first cassette mechanism 1 is brought into a paused state, and this switch S3 turns on the second cassette mechanism 1. When the first cassette mechanism 1 is temporarily stopped, the second cassette tape drive motor 2 is also temporarily stopped. Configure it to stop,
Therefore, when a signal reproduced by the first cassette mechanism 1 is to be recorded by the second cassette mechanism 2, the pause button provided on the tenth cassette mechanism 1 can be operated to arbitrarily switch between the first and the twentieth cassette mechanisms. It has the advantage that the seven-node mechanism can be put into a paused state and released at the same time, and its operation is extremely easy.

In the embodiment, the motor drive circuit of the second cassette mechanism 2 is controlled to bring the second cassette mechanism 2 into a paused state, but the second cassette mechanism 2 [1] In the same way as the cassette mechanism 1 shown in FIG. 1, for example, the configuration may be such that the vinyl roller that drives the cassette tape is temporarily moved away from the cassette tape. In this case, it is also possible to separately provide a plunger driven by the switch S5 and use this plunger to temporarily move the pinch roller away from the cassette tape.
The pinch roller driving means 72-' of the second cassette mechanism may be mechanically connected to each other so that when the pause button is pressed, the two are interlocked with each other.

As is clear from the above embodiments, according to the present invention, the first
By operating the Kaseno 1 mechanism of the 1st Kaseno 1-mechanism, the 20th Kaseno 1 mechanism can also be put into the suspended state at the same time, and therefore the 10th Kaseno 1 mechanism When recording the signal reproduced by the mechanism while editing it with the 20th CANANO 1 mechanism, the operation is very easy and it is extremely advantageous in practice.
