にある。 The gist of the present invention is that the rotation of the motor pulley is transmitted to the winding-side transmission wheel and the unwinding-side transmission wheel via the belt, and the rotation of the winding-side transmission wheel is transmitted through the winding pulley that moves toward and away from the winding side. The rotation of the rewind side transmission wheel is transmitted to the rewind reel table via the rewind pulley that moves toward and away from the rewind, and is also interlocked with it by pressing the rewind button. The rewinding lever is provided with a rewinding lever that is pressed and pressed, and the rewinding lever engages the lock pin of the actuating piece that pivots the rewinded transmission wheel in the pressing position, and the rewinding pulley is unwound and the transmission wheel and reel are reeled. At the same time, the take-up pulley is moved away from the take-up side transmission wheel, and at the end of the tape rewinding operation, the unwind pulley is moved between the unwind transmission wheel and the rewind reel stand. The locking pin of the actuating piece and the rewinding lever are disengaged from each other when the rewinding lever is pressed, and the device is brought into a reproducing operation state.
The purpose of this is to be able to repeat the playback operation immediately after rewinding the tape.
The purpose of the present invention is to provide a mechanism capable of repeating playback, rewinding, and playback. Another object of the present invention is to provide a mechanism that can perform the above-mentioned auto-replay operation simply by utilizing the force generated within the mechanism that drives the tape, without using any secondary means such as a plunger. The present invention provides a means suitable for use as an auto-repress mechanism in a small portable type device, since the entire device can be made smaller by eliminating the need for secondary means such as a plunger.

れている。 Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 shows the playback operation state of the device, Fig. 2 shows the rewind operation state of the device, and Fig. 3 shows the automatic transition from the rewind state to the playback state at the end of the tape rewind operation. This shows the part that is about to be switched to. In the figure, 1 is a motor pulley, the output of which is transmitted via a belt 2 to a winding side transmission wheel 3 and a rewinding side transmission wheel 4. The rotation of the winding-side transmission wheel 3 is controlled by the winding pulley 5 that moves into contact with and moves away from the winding-side transmission wheel 3.
The rotation of the rewind-side transmission wheel 4 is transmitted to the rewind reel base 8 via the rewind pulley 7, which moves into and out of contact. The above unwinding side transmission wheel 4
is pivoted on an actuating piece 9, which has a locking pin 10 and a spring 11 latched at one end.
As shown in the figure, it is biased to rotate clockwise about the shaft 12. The unwinding pulley 7 is connected to an arm 13 supported by a shaft 12.
The arm 13 is supported by a spring 14.
is about to contact both the rewind side transmission wheel 4 and the reel stand 8 because it is biased clockwise in the figure. The take-up pulley 5 is pivotally supported by a sliding piece 15, and the sliding piece 15 is always urged downward in the figure by a spring 16, so that the take-up pulley 5 and the take-up side transmission ring 3 are connected to each other. It is about to contact both sides of the take-up reel stand 6. Next, reference numeral 17 is a rewind lever connected to the rewind button 18, which is biased downward in the figure by a spring 19, and has a lock stepped portion 20 for engaging with the lock pin 10 of the operating piece 9. , a cam portion 22 for cam-guiding the pin 21 of the arm 13 that pivotally supports the rewinding pulley 7, and an abutting portion 23 that abuts against the sliding piece 15. Then, when the rewinding lever 17 is pressed until its locking step 20 engages with the locking pin 10, the rewinding lever 17 is locked.
The pin 21 of the arm 13 is guided by the valley of the cam part 22, and the unwinding pulley 7 is connected to the unwinding side transmission wheel 4.
and the reel stand 8 , and the other contact portion 23 presses the sliding piece 15 to separate the take-up pulley 5 from the take-up transmission ring 3 and the reel stand 6 .

リ5が伝導輪3とリール台6から離れている。 FIG. 1 shows the state of playback operation. That is, the output of the motor pulley 1 is transmitted to the belt 2, the transmission wheel 3,
The signal is transmitted to the take-up reel stand 6 via the pulley 5, and a tape (not shown) is being played back. At this time, the transmission wheel 4 and the pulley 7 are separated. Next, the rewind button 18 is pressed, and the lever 17 is pushed to the position where its lock portion 20 engages with the lock pin 10 of the actuating piece 9, and the engagement is locked as shown in FIG. The pin 21 is the cam part 22
As the arm 13 rotates clockwise by the force of the spring 14, the pulley 7
Since the tape contacts the transmission wheel 4 and the reel stand 8, the output of the motor pulley 1 is transmitted to the rewind reel stand 8 and the tape is rewound. At this time, the sliding piece 15 is pressed by the contact portion 23 of the lever 17, so that the pulley 5 is separated from the transmission wheel 3 and the reel stand 6.

るものである。 The above-mentioned operation is rewinding, but when the rewound tape reaches the end, the rotation of the rewind reel stand 8 stops due to the tension of the tape, so the pulley 7 is moved from the unwind pulley 7 to the reel stand 8. Due to the transmitted rotational force R, the contact point with the reel stand 8 is used as a point of force to push the pulley 7 out, and the rotational force of the transmission wheel 4 also works to push the pulley 7 out.
As shown in the third figure, the arm 13 rotates clockwise as shown by arrow P, and the pulley 7 pushes the transmission wheel 4. Therefore, the actuating piece 9 moves to the third position with the shaft 12 as a fulcrum.
Rotate counterclockwise in the diagram to lock pin 1.
0 is disengaged from the lock portion 20, and the lever 17 is released.
will return. By returning lever 17, arm 1
3 is guided by the peak of the cam portion 22, the rewinding pulley 7 separates from the transmission wheel 4 and reel stand 8, and the sliding piece 15 returns to its original position, causing the take-up pulley 5 to move away from the transmission wheel 3 and reel stand 8. Since it comes into contact with both sides of the table 6, it immediately enters the playback state as shown in the first diagram.

適な手段を提供できるものである。 As described in detail above, when the lever 17 is positioned at the pressing position and the lock portion 20 is engaged with the pin 10, the pulley 7 is brought into contact with both the unwinding transmission wheel 4 and the reel stand 8, and the other The take-up pulley 5 is separated from the take-up transmission wheel 3 and reel stand 6, and the tape is rewinded. When the tape reaches its end, the pulley 7 is moved by the reaction force generated from the stoppage of rotation of the rewind reel stand 8. The transmission wheel 4 and the actuating piece 9 are rotated by the protrusion, and the lever 1 is rotated.
7, and in the unlocked state, bring the take-up pulley 5 into contact with both the transmission wheel 3 and the reel stand 6, and release the rewind pulley 7 from both the transmission wheel 4 and the reel stand 8, and immediately Since the tape is moved to play back, a new rewind/replay mechanism can be provided, and the rewind/replay can be performed using the output generated from the tape drive mechanism without using a secondary means such as a plunger. Furthermore, since a plunger or the like is not required for this operation, it is possible to provide a suitable means as a rewind/replay mechanism for a small, portable magnetic recording/reproducing device.
