21 may bend and get over the small cassette stopper 213 or the large cassette stopper 214 and enter the inside of the lid.

This is because the end face 221 of the lid 220 of the cassette is formed of a thin plastic plate as shown in FIG. 18, and its central portion is particularly easily deformed.

(2) Since a single cassette stopper is used, the posture of the cassette is not stabilized when the cassette is inserted or the cassette is pushed out, and the cassette is inclined and the cassette inserting operation and the cassette pushing operation are performed smoothly. May not be.

The present invention solves the above-mentioned conventional problems, prevents the cassette stopper from entering the inside of the lid of the cassette, and allows the cassette to be inserted and pushed out in a stable posture. The purpose is to provide a cassette storage shelf.

[0015]

A shelf board supporting the inserted small cassette or large cassette, and a pair of small cassettes projecting above the shelf board and guiding the insertion of the small cassette when the small cassette is inserted. When the small cassette is inserted, it is disposed between the guide and the pair of small cassette guides, and when the small cassette is inserted, the end face of the lid that can be opened and closed abuts and slides together with the small cassette. A small cassette stopper that stops when inserted to a predetermined position, and an elevating mechanism that lowers the small cassette guide and the small cassette stopper so as not to hinder the insertion of the large cassette when inserting the large cassette, It is arranged behind the small cassette stopper in the cassette insertion direction, and when the large cassette is inserted, the end face of the lid comes into contact with In a cassette storage shelf provided with a large cassette stopper that slides together with the cassette and stops when it is inserted to a predetermined position, the cassette stopper comes into contact with the side of the end face of the lid of the cassette. A pair was arranged near the small cassette guide.

[0016]

When the cassette is inserted, the side of the end face of the lid which is openably and closably attached to the front end of the cassette comes into contact with the cassette stopper, and the side of the end face of the lid is supported by the cassette. Therefore, it is possible to prevent the cassette stopper from intruding inside the lid due to the presence of the cassette without being easily deformed. Also, since the left and right sides of the cassette are supported by the cassette stopper, the cassette can be inserted straight without tilting the cassette left and right when inserting the cassette.

It has become.

Then, in order to take out the small cassette 2 or the large cassette 3 from the cassette storage shelves 1,..., The cassette transfer device moves to the front of the cassette storage shelf 1 in which a desired cassette is stored, and is operated by an operation member. When the cassette pushing mechanism 14 is pressed, the small cassette stopper 8 and the large cassette stopper 9 descend as shown in FIG. 8, and then the cassette pushing member 13 moves to the cassette delivery port 21 side, as shown in FIG. As described above, the cassette is pushed out from the cassette delivery port 21 toward the cassette transfer device.

The shelf substrate 4 is formed of a metal plate in a rectangular shape, and as shown in FIG.
23, the notches 24 ... 24 for allowing the small cassette stopper 8 to slide out and slide in and out, and the large cassette stopper 10 to slide out.
25, a notch 26 for allowing the shutter 11 and the cassette pushing member 13 to protrude and retract, and a notch 27 for sliding the cassette pushing member 13 are formed.

Between the pair of small cassette guides 5 and 5 (inside) on the upper surface of the shelf substrate 4, support reference surfaces 31...
Outside the pair of small cassette guides 5, 5, a pair of left and right support reference surfaces 32, 32 for a large cassette are formed so as to protrude.

The supporting reference surfaces 31, 31 for the small cassette
The front end of the small cassette 2 is located behind the front ends of the small cassette guides 5 and 5 in the cassette insertion direction from the cassette storage opening 21 side as shown in FIGS. At the beginning of insertion, the small cassette 2 does not abut the small cassette supporting reference surfaces 31, 31, and the small cassette 2 rides on the small cassette supporting reference surfaces 31, 31 when a predetermined amount is inserted. The small cassette is supported at a reference position.

This configuration is achieved by lowering the support reference surfaces 31, 31 for small cassettes to the rear in the cassette insertion direction so that the support reference surfaces 3 for these small cassettes are lowered.
The small cassette guides 5, 5 from the upper surface of the shelf substrate 4 at the entrance portion on the side of the cassette accommodating opening 21 where no 1, 1 is formed.
This is to prevent the small cassette 2 from getting on the small cassette guides 5, 5 by making the projecting height of the small cassette relatively high.

The support reference surfaces 32, 3 for the large cassette
The reason why the small cassette 2 is disposed before the small cassette supporting reference surfaces 31 is to reduce the difference between the depth of the guide groove of the large cassette 3 and the height of the small cassette guide 5 when the large cassette 3 is inserted. This makes it easy to insert the large cassette 3.

The small cassette guides 5, 5 are shown in FIGS.

The height of the guide groove 33 is substantially the same as the height of the guide groove of the large cassette 3, and the height of the remaining portion (hereinafter referred to as the rear portion) 34 is greater than the height (depth) of the guide groove of the large cassette 3. It is formed to be high and has a height step δ1 between the front part 33 and the rear part 34, and the width of the rear part is made slightly smaller than the width of the guide groove.
The notch 35 on the inner surface side of
The width of the front portion 33 is made smaller than the width of the front portion 4, a step δ 2 is provided between the front portion 33 and the rear portion 34 in the width direction, and the small cassette guides 5, 5 are fitted into the guide grooves of the large cassette 3. When they are combined, these small cassette guides 5,
The inner surface of 5 does not contact the inner surface of the guide groove.

Since the small cassette guides 5 and 5 are configured as described above, when the large cassette 3 is inserted along the small cassette guides 5 and 5 to the length of the guide groove, the large cassette 3 Detection rollers 17 of the lifting mechanism 9 on both left and right sides
Is pushed outward to lower the small cassette guides 5, 5. At this time, the inner surfaces of the small cassette guides 5, 5 are not in contact with the inner surfaces of the guide grooves of the large cassette 3 as described above. Therefore, it descends smoothly without receiving frictional resistance.

Then, after the small cassette guides 5, 5 are lowered, the large cassette 3 is further inserted into the cassette storage shelf 1.

The reason why the rear portion 34 of the small cassette guides 5, 5 is raised as described above is to prevent the small cassette 2 from riding on the small cassette guides 5, 5 when the small cassette 2 is inserted. is there.

That is, the support reference surface 3 for the large and small cassettes
The protruding height of the small cassette guides 5, 5 from the first and second cassettes 32 is determined by the height (depth) of the guide groove provided in the large cassette 3, and cannot be increased unnecessarily.

However, the rear portion 34 of the small cassette guides 5, 5 descends below the shelf substrate 4 when the portion corresponding to the length of the guide groove of the large cassette 3 is inserted, so that it is higher than the guide groove. can do.

Then, the rear portion 34 of the small cassette guides 5, 5 is raised, and the support reference surfaces 3 of the large and small cassettes 2, 3 are raised.
By increasing the step between the small cassettes 1 and 32, the small cassette 3 is prevented from running on the small cassette guides 5 and 5.

The small cassette stoppers 8 are arranged so as to form a left and right pair near the pair of left and right small cassette guides 5 and 5, and when the small cassette 2 is inserted, the lid of the small cassette 2 The pair of small cassette stoppers 8, 8 are in contact with the left and right sides of the end surface 7 of the pair 6.
