Abstract

PURPOSE:To load a cassette with a little force, by excluding a reel driving member to outside of a cassette loading path with the loading of a cassette and automatically restoring the reel driving member and latching the member to the reel after the loading is finished. CONSTITUTION:When a cassette 8 is loaded to a cassette insertion inlet 2, the cassette 8 contacts the slope of a reel driving member 9 on the way of loading, and as the loading of the cassette 8 is progressed, the member 9 is depressed against a spring 17. When the loading of the cassette 8 is further progressed and a reel hub is located above the member 9, the member 9 is energized with the spring 17 upward and latched to the reel. To unload the cassette 8, a detaching force is exerted to the cassette 8, the member 9 can be unloaded with depression in the same way as the loading. Thus, the loading of the cassette can be done with a comparatively small force with a simple construction.

The tape recorder of this embodiment uses a tape cassette in which a pinch roller is rotatably housed in a case in advance. In the figure, reference numeral 1 denotes a box-shaped cassette storage part, and the negative ml side thereof is a cassette insertion slot 2. The cassette storage section 1 is fixed to the chassis 6 via pillars 3 and 4. A shaft 7 is rotatably and vertically movably supported by a bearing 6 fixed to the chassis 6, and one end of the shaft 7 engages with a reel hub (not shown) built into a tape cassette 8. The reel drive member 9 that rotationally drives this is FMy. This reel drive member 9
has a plurality of drive claws 91 that engage with the pins of the reel hub.
The upper surface of the claw 9a is an inclined surface that slopes from the center of the reel drive member 9 toward the outer periphery. Therefore, the upper surface of the reel drive member 9 has a conical shape. In addition, a pulley 10 is attached to the lower end of the shaft 7.
.. Friction plates 119 and disks 12 made of felt or the like are arranged one on top of the other. The pulley 10 and friction plate 11 are rotatable and movable up and down relative to the shaft 7, and the disc 12 is rotatable relative to the shaft 7.
Although it rotates integrally with 0, it can only move up and down. These three members are arranged between a pair of stoppers 13 and 14 attached to the shaft 7, and are urged against the upper stopper 13 by a leaf spring 15. Rotation from a motor or the like is transmitted to the pulley 1o via a rubber belt 16. Further, a compression coil spring 17 is disposed between the reel drive member 9 and the chassis 6, and the force of the coil spring 17 always presses the reel drive member 9 upward in the figure. This reel drive #1 member 9 is inserted into the cassette storage section 1 through a hole 18 provided on the bottom surface of the cassette storage section 1, and protrudes into the cassette insertion path -L.

As shown in FIG. 1, when the cassette 8 is moved horizontally and inserted into the cassette insertion slot 2, the cassette 8 is
comes into contact with the inclined upper surface of the reel drive member 9, and as the cassette 8 is inserted, the reel drive member 9 is pushed down. When the cassette 8 is further inserted and the reel hub is positioned above the reel drive member 9, the reel drive member 9 or the compression coil is raised again by the force of the spring 17 and engaged with the reel hub. Although not shown, the capstan and magnetic head are located at the back of the cassette storage section 1, so when the tape cassette is inserted into the proper position, the pinch roller built into the cassette is automatically pressed against the capstan.
Since the magnetic head is brought into contact with the magnetic tape, a motor (not shown) starts rotating, and the capstan and reel driving member e are rotated, thereby playing back or recording the magnetic tape. In this case, one end of the cassette is exposed to the outside of the cassette storage section 1.

Next, when ejecting the tape cassette, if a pulling force is applied to the cassette 8 after the motor has stopped, the reel drive member 9 will descend once and rise again as described above, making it possible to pull it out to the outside. can. Of course, a separate cassette ejection button may be provided, and when this button is pressed, the reel drive member 9 is lowered, and the cassette is pushed out by a spring provided at the back of the cassette storage section 1.

In the above embodiment, one reel driving member 9 has been described, but two reel driving members 9 may be used depending on the structure of the cassette. Further, the apparatus of the above embodiment can be similarly applied to a system in which the tape is run only by the rotational force of the reel without using a capstan.

As explained above, in the cassette type tape recorder of the present invention, when inserting the cassette into the cassette storage section, the reel drive member, which normally protrudes onto the cassette insertion path in the cassette storage section, is pushed down by the cassette, and the cassette is placed in a fixed position. When the reel is inserted up to that point, it is automatically moved back and engaged with the cassette by the force of the elastic means, so the moving mechanism can be reduced to just the reel drive member and its related parts, making the configuration simple and easy to assemble. Of course, the movement of the reel drive member is carried out gradually in conjunction with the insertion of the cassette, so there is no large impact noise, and the insertion operation of the cassette can be performed with a relatively small force. is large.
