Abstract

PURPOSE:To surely and quickly hold and release a cassette in and from a cassette holder by turning a lever against the turning force of a spring to detach a detaining member from a recessed part at the time when the cassette is in a cassette insertion position. CONSTITUTION:A lever 12 freely turnably provided in a cassette holder 2 and a spring 14 which has one end attached to the lever 12 and gives the turning force to the lever 12 are provided. When a cassette 1 is in the cassette insertion position, a detaining member 11 and a recessed part 5 are released from each other by turning of the lever 12; and when the cassette 1 is moved from the cassette insertion position, the lever 12 is turned in accordance with the turning force of the spring 14, and the detaining member 11 is detained by the recessed part 5 in accordance with the energizing force of an elastic member 10. Thus, the cassette is surely and quickly held by the cassette holder and released from the cassette holder.

Next, the operation of the DAT having the above configuration will be explained. When the cassette 1 is inserted into the cassette holder 2 from the direction of the arrow A, the cassette 1 is pressed as shown in FIG.
If the cassette holder 2 and the ja2 are pressed by the urging force, the cassette holder 2 is held between the cassette holder 2 and the ja2. In this cassette/insertion position, as shown in FIG. 3, the protrusion 15 is in contact with t<-12, and the lever 12 is prevented from rotating due to the force of the spring 14. . As a result, the locking member 11 is removed from the recess 5, and the forceps 1-] are inserted into the cassette holder 2 through the space 11-.

In the opposite case to the above movement flE, that is, when the cassette 1 moves f5 from the cassette I mounting position to the cassette insertion position l\, the lever 12 comes into contact with the protrusion I5 during the movement.
The lever 12 rotates against the biasing force of the spring 14, pushing up the locking member 11 onto the lever 12, and the locking member 11 is released from the recess 5, so that the cassette 1 is moved inside the cassette holder 2 at the cassette insertion position. is held only by the biasing force of the presser flap 3, and the cassette 1 is ejected from the cassette holder 2 in a straight line. Furthermore, the distance that the tip of the lever 12 rotates about the pin 13 is significantly larger than the distance that the protrusion 15 rotates the lever 12, and the locking member 11 is released from the recess 5 that much more quickly.

In the above embodiment, the elastic member 10 and the locking member 11 are separated, but the elastic member and the locking member may be integrated. In addition, a protrusion 15 is provided on the base 4.
Instead of providing the lever, for example, a bent part may be formed on the lever and the bent part may come into contact with the end surface of the base plate.
Furthermore, this invention can be used as a cassette loading device.
Although the AT has been described, it goes without saying that it can also be applied to, for example, a video tape recorder.
