Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation control device for a tape recorder.

Conventional tape recorders, especially portable tape recorders, are often equipped with a review function (rewinding in playback mode, hereinafter simply referred to as review); Usually the buttons are not locked.

Therefore, even when performing a review operation that can return to the playback state for a long time, the rewind button must be continuously pressed by hand. On the other hand, for those without a review device,
If you perform a rewind operation during playback, the playback button will be unlocked, so even if you have automatically stopped the tape at the end of the tape after rewinding, you will have to press the playback button again to start playback again. It was a hassle to have to put it in play mode. The present invention eliminates this inconvenience, and when the rewind button is pressed during playback, the rewind operation is performed while the playback button is locked.At this time, the rewind button is also locked, and the tape automatically stops when the end of the tape is reached. To provide a device in which the device operates to unlock only a rewind button and automatically restart a playback state.

In the present invention, the first lock plate locks the rewind operation plate, the second lock plate locks the playback operation plate, and the movement of the first lock plate is selectively transmitted to the second lock plate. A connecting arm is provided, and a rewind operation plate is used to selectively operate the connecting arm.

An embodiment of the present invention will be described in detail below.

FIG. 1 shows the stopped state of this device. Play button 3,
A fast forward button 3', a rewind button 3', and a stop button 3'' are fixed, and return springs 4, 4' are installed between the chassis 1 and each operation plate 2, 2', T, 2''. , 4'', 4〃' are installed.

The upper surface of the chassis 1 has a long hole 6 on the right end into which the planting pin 5 is fitted, and the left end is formed on the rewind operation plate τ so as to engage with a protrusion 8 protruding from the hole □ of the chassis. The configured connecting arm 9 is mounted, and a tension spring 10 is stretched between the connecting arm 9 and the chassis 1.

This spring 10 has the function of constantly rotating the connecting arm 9 counterclockwise and the function of pulling it to the right. Furthermore, the connection arm 9 is provided with a notch 11 that is open on the push button side, and in the stopped state shown in FIG. Engaging portions 14 and 15 provided on each of the two lock pans 13 are facing. On the left side of the chassis 1, a bent portion 16 of the lock pan 12 protrudes from the upper surface of the chassis, and a spring 17 is stretched between the bent portion 16 and the chassis, urging the lock pan 12 to the right. There is.

The other one of the bent portions 16 faces an output member 18 of a known automatic stop mechanism so as to be able to come into contact with it. When the automatic stop mechanism is activated due to the end of the tape, the output member 18 moves to the left, comes into contact with the lock bang 12, and is configured to move this to the left. FIG. 2 is a rear view of the chassis in the stopped state in FIG. Each is attached so that it can be moved left and right.

On the push button side of these lock buttons, there are lock parts 23, 23', 23 corresponding to the play, fast forward, and rewind operation panels.
” and a lock release portion 24 corresponding to the stop operation plate are formed, and on the other hand, the lock bangs 12 and 13 are formed on the operation plate side.
Actuating parts 25, 25', 25'', 25 for operating the
A spring 26 is stretched between the lock van 13 and the chassis 1, and the lock van 13
is urged to the left, and the lock bang 12 is also urged to the left by the spring 1r. Next, the operation of this apparatus will be explained with reference to FIGS. 3 to 5.

From the stopped state shown in Figure 1, press the playback button and playback operation panel 2.
When the actuating portion 25 of the second lock bang 13 is engaged with the lock portion 23 of the second lock bang 13, the regeneration state shown in FIG. 3 is obtained.

Note that although the tape drive mechanism is not particularly illustrated in FIG. 3, this tape drive mechanism is well known and does not particularly require explanation in the present invention, so a description thereof will be omitted. To cancel this regeneration state, press the stop button 3'1, and the actuating part 25'1 of the stop operation plate 2'1 moves the lock release part 24 to the right in Fig. 2 (in Fig. 3). (moves to the left), the engaging part 1 of the lock bang 12
4 presses the left wall surface of the notch 11 of the connecting arm 9 to the left. Therefore, the engaging portion 15 of the locking bang 13 is pressed against the right wall surface of the notch of the connecting arm 9, and the locking bang 13 also moves to the left. As a result, the lock part 23 and the actuating part 2 in FIG.
5 is disengaged, and the playback button 3 is returned to its original position by the force of the return spring 4, resulting in a stopped state. When the end of the tape is reached during the playback operation, a known tape end detection and automatic stop mechanism is activated to move the output member 18 to the left in FIG.

As a result, it comes into contact with the bent portion 16 of the lock band 12, and by moving this also to the left, the play button 3 is unlocked in exactly the same way as when the stop button 3' is pressed. FIG. 4 shows the state in which the rewind button was pressed to change from the playback state shown in FIG. 3 to the review state.

When you start pushing the rewind button y, the protrusion 8 of the rewind operation plate 2'' rotates the entire connecting arm 9 clockwise, and the notch 11 and the engaging parts 14 and 15 of the lock bangs 12 and 13 are connected to each other. disengage.

If you push it further, the lock part 231t of the lock bang 12 will open.
! ) To press the convex portion of the operating portion 25ζ of the operation plate
In the figure, the locking bang 12 is once moved to the left, and when locking is completed, it returns to the right. That is, since the connection arm 9 and the lock bangs 12, 13 are disengaged by pressing the rewind button, the movement of the lock bang 12 is not transmitted to the lock bang 13, and the playback button remains locked. When the two playback and rewind buttons are pressed, the internal mechanism is not shown, but the tape is rapidly rewound because the rewind state is prioritized. When the end of the tape is reached in this review state, the automatic stop mechanism is activated to move the output member 18 to the left (the state indicated by the two-dot chain line). As a result, the lock bang 12 moves to the left and the rewind operation plate 7 is unlocked. Therefore, rewind button 3
``2'' returns to its original state.At this time, the connecting arm 9 whose tip is in contact with the rewind operation plate 2''O protrusion 8 due to the biasing force of the tension spring 10 also rotates counterclockwise; As shown in the figure, it comes into contact with the engaging portion 14 of the lock bang 12 and cannot return to its original state. That is, since the engaging part 14 does not fit into the notch 11 of the connecting arm 9, the movement of the locking bang 12 is not transmitted to the locking bang 13, and the playback button remains locked. On the other hand, the rewind button 3'I: 7) is configured to detect the return operation and also return the automatic stop mechanism, so the output member 18 returns to the right (two-dot chain line) in Fig. 5. do.

For this reason, the tension of the spring 17 also moves the locking bang 12 to the right, so the movement of the engaging portion 14 and the force of the tension spring 10 cause the connecting arm 9 to rotate counterclockwise and move into its notch 11. The engaging portion 14 is accommodated in the. or,
As for the tape running, the reproducing operation starts at the same time as the rewind button is reset. In the above explanation, the rewinding operation was performed and the automatic stop mechanism was used to switch the playback state at the end of the tape. However, even if the stop button is pressed in the middle of this review state, the same switching as described above will occur. Of course it can be done.

Also, you can simply rewind (rewind) from the stopped state regardless of the review state.
When the rewind button (or fast forward button) is operated, the rewind button (or fast forward button) is naturally unlocked at the end of the tape (or by operating the stop button) and returns to the stopped state.

Since the present invention is configured as described above, there is no need to keep pressing the rewind button by hand to maintain the single review state as in the past, and there is no need to press the play button again after auto-stopping at the end of the tape in the rewind state. The effect of this device is even more pronounced when the present device is applied to a car-mounted tape recorder.

Further, the structure of the present invention is extremely simple and has extremely practical effects such as being able to be provided at a low cost.
