Abstract

PURPOSE:To obtain a sufficient press-contacting force through a small amount of movement of a recording and reproducing lever by performing a major part of the movement of a pinch roller in a capstan direction with the rotary pressing force of a pinch roller lever and nearly limiting the recording and reproducing lever only for the purpose of obtaining a pressing force to the capstan. CONSTITUTION:The pinch roller lever 48 supporting the pinch roller 49 is rotated in a energized state with a pressing spring 59 to a position where the roller 49 is nearly in contact with the capstan(Ca) 62. Then, the roller 49 is sufficiently press-contacted to Ca 62 with the recording and reproducing lever 68, and because of their closeness to each other, only moving the small amount. Also, the lever 48, which is moved to a recessed position where, as the roller 49 is detached from the Ca 62, the loading/unloading of a cassette is not interferred, is locked by a pinch lock member 100. In addition, the lever 48 is moved to the recessed position by a cover opening button 107 at the time of opening the cover, and the lever 48 is unlocked with the member 100 by the lock releasing member 114 at the time of closing the cover. Thus, the stroke of the lever 48 is made small, and the roller 49 is properly positioned.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel tape player. More specifically, the play lever that presses the pinch roller onto the capstan by sliding it requires only a small rotation stroke of the pinch roller lever, and when the tape cassette is attached and detached, the pinch roller is attached and detached. It seeks to provide a new tape player that keeps it out of the way.

[0002]

2. Description of the Related Art A mechanism is simplified by providing a play lever, which is provided slidably and moves in a predetermined direction to form a recording mode or a reproduction mode, with a function for pressing a pinch roller onto a capstan. It is possible to reduce the size by

[0003]

However, the pinch roller moves not only between the position where it is crimped to the capstan and the position where the crimp is released, but also to a position where it does not interfere with the attachment and detachment of the tape cassette. It needs to be held, which requires a considerable travel stroke.

In order to move the pinch roller by the above-mentioned play lever, for example, a member supporting the pinch roller by providing an inclined cam edge on the play lever, for example,
It is conceivable that the pinch roller lever is pressed by the inclined cam edge to move the pinch roller, but in order to increase the movement stroke of the pinch roller, the inclined cam edge must be lengthened or the inclination thereof must be made tight.

If the length of the inclined cam edge is increased,
There is a problem that the moving stroke of the play lever has to be increased, and miniaturization is hindered in order to secure the moving stroke. Also, if the inclination of the inclined cam edge is tight, the movement of the play lever is large. Not only does it require force and the operability deteriorates, but there is also a problem that the operation itself becomes impossible if the inclination is too tight.

[0006]

In order to solve the above problems, the tape player of the present invention includes a pinch roller lever that is rotatably supported by a chassis and rotatably supports a pinch roller at its pivot end. , The pinch roller lever is urged to rotate the pinch roller in the direction of approaching the capstan, and the pinch roller lever is slidably supported by the chassis to slide the pinch roller lever into the pinch position. The play lever that moves the roller to the crimping position where it is crimped to the capstan, and the pinch roller lever that is in the retracted position where the pinch roller is largely separated from the capstan and does not interfere with the attachment and removal of the tape cassette to the cassette mounting recess. Pinch lock means to lock,
Pinch moving means for moving the pinch roller lever to the retracted position when the lid for opening and closing the cassette mounting recess is opened, and for locking the pinch lock means when the lid reaches the closing position for closing the cassette mounting recess. Lock release means for releasing the lock of the pinch roller lever to the retracted position by moving it to the release position, and the movement of the pinch roller lever by the play lever to the crimping position is performed from the position rotated by the elastic means. It was made to be done.

[0007]

Therefore, in the tape player of the present invention, most of the movement required for the pinch roller toward the capstan is performed by the elastic means for urging the rotational force to the pinch roller lever, and the pinch by the play lever is used. Since the movement of the roller can be substantially limited only to obtain the crimping force to the capstan, it is possible to obtain a sufficient crimping force without increasing the movement stroke of the play lever.

Moreover, since the pinch roller lever is locked at the retracted position when the lid is opened, which is a prerequisite for the tape cassette attaching / detaching operation, there is no problem in attaching / detaching the tape cassette.
