Description

[Detailed Description of the Invention] The present invention relates to a magnetic recording and reproducing device equipped with two tape drive units, and its purpose is to record the playback signal from one tape drive unit into the other tape drive unit, so-called dubbing. The purpose is to make it possible to perform it with simple operations.

In recent years, magnetic recording and reproducing apparatuses in which two tape drive sections are housed in the same housing have become commercially available. This type of magnetic recording/reproducing device not only allows two tape drive units to operate separately, but also allows both drive units to operate simultaneously and record the playback signal from one drive unit using the other drive unit. This device is convenient because it allows dubbing and continuous operation of both drive units for long-term recording and playback.

However, while it is convenient, it has the disadvantage that it is complicated and difficult to operate, especially when dubbing. In other words, when dubbing, press the playback button and pause button on one tape drive to pause playback, and press the record and pause buttons on the other tape drive to pause recording. The system is designed to start dubbing by simultaneously releasing the pause buttons of the two tape drive units, which requires operating four operation buttons, which is complicated and requires two pause buttons. There was a drawback that dubbing would not be performed properly if the timing of the button release operation was incorrect.

The present invention is intended to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings. FIG. 1 is a front view of the apparatus of this embodiment, in which 1 is the cabinet, 2 and 3 are the cassette mounting parts of the first and second tape drive sections provided on the front surface of the cabinet, and 4 and 5 are the two tapes mentioned above. A group of tape running operation buttons of the drive section, 6 is a level indicator, 7 and 8 are dubbing buttons, and 9 is a power button. FIG. 2 shows the main circuitry of the apparatus, in which numeral 10 is a first tape drive section for reproduction only, and numeral 11 is a second tape drive section capable of recording and reproduction. The first tape drive unit 10 includes a playback head 10a, a playback amplifier 10b, a tape drive motor 10c, and a playback switch 10d that is closed by pressing the playback button 4a.The second tape drive unit 11 includes a recording head 11a, recording amplifier 11
b, a tape drive motor 11c, and a recording switch 11d that is closed by pressing the recording button 5a.

Reference numeral 12 denotes a power terminal to which power +B is applied when the power button 9 is pressed.Power is directly supplied from this terminal 12 to the second tape drive section 11, and the first switch is opened when the dubbing button 7 is pressed. Power is supplied to the first tape drive section 10 via 7a. The first switch 7a is configured to work in conjunction with a second switch 7b which is closed by pressing the dubbing button 7, and these two switches 7a and 7b connect a playback switch 10d and a recording switch 11d in parallel. There is. The playback switch 10d and the recording switch 11d function as switches for starting the rotation of the tape drive motors 10c and 11c. The output terminal of the reproduction amplifier 10b of the first tape drive section 10 and the input terminal of the recording amplifier 11b of the second tape drive section 11 are connected via a third switch 8a which is closed by pressing the dubbing button 8. It is connected.

The operation of the above embodiment will now be explained.
When the dubbing buttons 7 and 8 are not pressed, the first to third switches 7a, 7b, and 8a are in the state shown in the figure, and when the power button 9 is pressed, the first and second tape drive units 10 , 11 are supplied with power. Therefore, if you press the playback button 4a, the playback head 1
0a moves forward and a pinch roller (not shown) comes into contact with the capstan via the tape, and at the same time, the playback switch 10d is turned on, the motor 10c rotates, and the tape is played back. When the recording button 5a is pressed, the recording head 11a moves forward, a pinch roller (not shown) contacts the capstan via the tape, the recording switch 11d is turned on, the motor 11c rotates, and recording is performed. In this way, when the dubbing buttons 7 and 8 are not pressed, the first and second tape drive units 10 and 11 can be operated independently.

Next, when the dubbing buttons 7 and 8 are pressed, the dubbing buttons 7 and 8 are locked in the pressed position by the push lock mechanism, and the first to third switches 7a, 7b, and 8a are opened, closed, and closed. state. When the first switch 7a is opened, power to the first tape drive section 10 is cut off. Therefore, the first tape drive section 10 is
Even if you press and lock a to enter the playback state, the tape does not run. After setting the first tape drive section 10 to the playback state in this way, when the recording button 5a of the second tape drive section 11 is pressed, the second tape drive section 11 enters the recording state and the recording switch 11d is pressed. , the first via the second switch 7b
Power is supplied to the tape drive section 10 of the tape drive section 10, and the tape drive section 10 enters the playback state. Then, the reproduction signal from the reproduction amplifier 10b is input to the second tape drive unit 11 via the third switch 8a and is recorded. Dubbing is performed in this manner.

As is clear from the above description, the second switch 7b is the recording button 5 of the second tape drive unit 11.
Since it is used to energize the first tape drive section when a is pressed, the connection need not be made as shown in the figure, but may be connected to the movable end side of the first switch 7a, for example. In addition, the first to third switches 7a,
The number of dubbing buttons may be reduced to one so that the dubbing buttons 7b and 8a are collectively linked. The reason why the dubbing button 8 is separate is to make it easier to set the recording level. That is, when only the dubbing button 8 is pressed and locked, the first tape drive section 10 is operated and the playback signal is inputted to the second tape drive section 11 to set the recording level to an appropriate level. I can do it. Further, the motors 10c and 11c are tape drive motors, but if the device is a motor drive operation type, this can be considered as a motor for driving the traveling operation mechanism of the device, and if it is an electromagnetic solenoid drive operation type device, it can be considered as a motor for driving the travel operation mechanism of the device. It can also be seen as a solenoid. Furthermore, the first and second tape drive sections 1
0 and 11 may be arranged in the opposite direction to that shown in the figure, in which case switch 10d is the recording switch and switch 11 is the recording switch.
d can be seen as a playback switch.

As explained above, the magnetic recording/reproducing apparatus of the present invention can perform dubbing with one operation by simply adding two switches, and can simplify the operation and improve operability.
