付けられたカセツトカバーである。Structure of a conventional example and its problems A conventional cassette mounting device will be explained based on FIGS. 1 to 6. In the figure, 1 is a main body of the apparatus, 2 is a cassette holder, and pins 2a and 2b are fixed to the upper ends of both sides in parallel to each other. Reference numeral 4 designates a rotary base plate located above the cassette holder 2, and has elongated holes 4a and 4b formed on both sides thereof. The cassette holder 2 is assembled into the rotary base plate 4 by inserting the pins 2a, 2b through the openings of the elongated holes 4a, 4b.
The rotary base plate 4 has a rotary center hole 4c, which is fixed to both sides of the cassette holder 2 connected to the rotary base plate 4 when it is coupled to the shaft portion 6a of the angle 6 on the chassis 12. Place pin 2c on chassis 2.
Guide groove 1 formed in the upper guide plate 10
Incorporate into 0a. Therefore, the cassette holder 2 is held by the rotating base plate 4. The cassette holder 2 has a guide plate 10 in its front and rear positions.
In order to receive positional control by the guide groove 10a, while performing a rotational movement together with the rotational base plate 4,
The pins 2a and 2b on both sides of the cassette holder 2 slide through the long holes 4a and 4b of the rotary base plate 4. Further, after the pin 2c enters the guide groove 10a, the stopper 9 having the pivot shaft 9a is attached to the guide plate 10, thereby acting as a stopper when the cassette holder 2 rises to the position from which the cassette 14 is taken out. In the figure, 3 is the operation button, 5 is the damper gear,
7 is a cassette damper, 8 is a spring, 11 is a rotating head cylinder, 13 is a reel stand, 15a
15d is a printed circuit board, 16 is a flexible printed circuit board, and 18 is a cassette cover attached to the upper part of the rotating board 4.

た。 In such an apparatus, when the cassette 14 is inserted into the state shown in FIG. 5 and then attempts to be lowered, the cassette 14 is inclined at a predetermined angle with respect to the horizontal. In other words, since the cassette 14 is parallel to the rotating base plate 4, the tip of the cassette 14 is considerably lowered, and the cassette opener 19 touches the guard panel 14a of the cassette 14.
There was a tendency for the pressure angle to increase when attempting to open. Therefore, when the cassette holder 2 is lowered to install the cassette 14, the cassette 14 tends to move forward due to the resistance of the cassette opener 19, making the installation of the cassette 14 very unstable. Furthermore, cassette holder 2
If the product is repeatedly lowered and then raised again without being fully seated,
The amount of movement of the cassette 14 gradually increases, causing problems such as the rear part of the cassette 14 catching on the tip of the cassette guide 20 and getting stuck in the middle.

This will be explained based on FIG. 12). First, a first embodiment will be explained based on FIGS. 7 to 10. As can be seen from FIG. 9, a recess 21a having a width and depth determined by the standard is formed on the back surface of the magnetic tape storage cassette 21, extending over the entire width of the cassette. Therefore, as shown in FIG.
is stored in the cassette holder 22,
By forming a protrusion 22a on the bottom of the cassette holder 22 that fits into the recess 21a, the position of the cassette 21 can be regulated. Furthermore, the cassette 2 is mounted on the inner surface of the upper part of the cassette holder 22.
There is one holding leaf spring 23, and the cassette 21 is always pushed downward. Therefore, the cassette recess 21a will not come off the cassette holder projection 22a within the cassette holder 22. Note that FIG. 10 is an enlarged cross-sectional view of the convex portion 22a. Therefore, in this first embodiment, even if the cassette 21 tends to shift within the cassette holder 22 due to the resistance of the cassette opener during the cassette loading operation, the position of the cassette 21 can be controlled.

A similar effect can be obtained by forming the resin molded product 26 provided at the tip of the resin molded product 26. The resin molded product 26 is fitted into the hole 22b of the cassette holder 22.
By doing this, as shown in FIG. 12, when inserting the cassette 21 into the cassette holder 22,
By bending the leaf spring 25 downward about the pin 24, the resistance when loading and unloading the cassette 21 can be reduced, and the operability can be improved.
