[Detailed description of the invention] The present invention relates to a pinch roller device, and its purpose is to provide a pinch roller mounting plate that is rotatably provided on a chassis, a stepped portion in the center, and both ends of the pinch roller mounting plate. A substantially dogleg-shaped locking hole is provided that is bent away from the rotation axis, and by locking the drive pin provided on the head base in the locking hole, the head base moves from the playback position to the stop position. To provide an apparatus in which a queue/review operation can be performed reliably by first rotating the pinch roller mounting plate largely and then rotating it little by little.

However, in order to move the magnetic tape at high speed, the pinch roller that moves as the head base moves must be completely separated from the capstan axis, but the magnetic head is in contact with the magnetic tape. Therefore, it is impossible to move the head base far back toward the stop position, which inevitably reduces the movement of the pinch roller, and there is a risk that the pinch roller may accidentally come into contact with the magnetic tape or capstan shaft.

Next, to explain the operation of the present invention, the first
4 and 4 show the reproducing state, in which the magnetic head 5 is in contact with the magnetic tape T, and the pinch roller 14 is also pinching the magnetic tape T with the capstan shaft 3. Therefore, as the reel stand 2 and capstan shaft 3 rotate in the direction of arrow A, the magnetic tape T also moves in the direction of arrow B for reproduction. When performing a review operation from this playback state, if you operate the review button (not particularly shown),
The head base 4 moves somewhat rearward as shown in FIG. At this time, the magnetic head 5 also moves backward, but remains in contact with the magnetic tape T.

As the head base 4 moves rearward, the drive pin 6 provided on the head base 4 moves to the stepped portion 11 of the locking hole 11 provided on the pinch roller mounting plate 10.
In order to rotate the pinch roller mounting plate 10 largely in the direction of arrow C in FIG.
4 is surely released from contact with the capstan shaft 3. Therefore, the magnetic tape T is rewound at high speed while remaining in contact with the magnetic head 5.

Next, to change the playback state from the playback state shown in FIGS. 1 and 4 to the stop state, by operating the stop button, the head base 4 moves significantly backwards as shown in FIG. 6, and the magnetic head 5 The contact with the tape T is released. As the head base 4 moves, the pinch roller mounting plate 10 first rotates greatly due to the engagement between the drive pin 6 and the stepped portion 12, as shown in FIG. Since the engagement with the part 12 is disengaged and the part moves into the relief hole 13 of the locking hole 11, its rotation becomes smaller than when it is engaged with the stepped part 12. In the above description of the operation, FIGS. 4 to 6 are views with the top plate of the pinch roller mounting plate 10 removed.

As mentioned above, the present invention is based on the pinch roller mounting plate 10.
A substantially dogleg-shaped locking hole 11 with a stepped portion 12 in the center and both ends bent in a direction away from the rotating shaft 9 of the pinch roller mounting plate 10 is provided in the locking hole 11, and the head base is inserted into the locking hole 11. Since the drive pin 6 provided on the head base 4 is locked, when the head base 4 moves from the playback position to the stop position, the engagement between the drive pin 6 and the stepped portion 12 causes the pinch roller mounting plate 10 to be pushed wide at first. After that, the pinch roller mounting plate 10 can be rotated little by little, so that even a small movement of the head base 4 will reliably separate the pinch roller 14 from the capstan shaft 3, ensuring reliable queue/review operations. Moreover, since the pinch roller mounting plate 10 does not follow the movement of the head base 4 to the end, the spring 15 that biases the pinch roller mounting plate 10 also has the effect of having a long life.
