Claim 2 of the present invention is a storage rack for both large and small cassettes applied to a cassette autochanger, etc., in which when a large cassette and a small cassette are selectively inserted into the cassette storage part, one of the large cassette and the small cassette is In addition, only when a pair of large cassette detection means arranged on both sides near the cassette insertion opening of the cassette storage section both detect a large cassette, the small cassette inside the cassette storage section is inserted. By configuring the cassette guide to escape into the cassette storage section, the structure is simplified and the small cassette can be easily inserted into the proper position.

C. PRIOR TECHNOLOGY The applicant of the present invention has previously disclosed, for example, the specification and drawings of Japanese Patent Application No. 63-84591 as an example of a storage shelf for large and small cassettes for a cassette autochanger using video cassettes. I have applied.

In this prior application, in a large and small cassette storage shelf configured to selectively store large cassettes and small cassettes in the cassette storage part, when inserting the large cassette into the cassette storage part, the inner wall of the pair of When inserting a small cassette into the cassette storage section, a pair of small cassette guides provided in parallel inside the pair of inner walls guides both sides of the small cassette. The center of the large and small cassettes is positioned over the center of the cassette storage section.

Further, the pair of small cassette guides are configured to be movable between the inside and outside of the cassette storage section, and when a large cassette is inserted into the cassette storage section, the pair of large cassette guides provided in the cassette insertion slot When the detection means simultaneously detect large cassettes, a pair of small cassette guide drive mechanisms driven by the pair of large cassette detection means causes the pair of small cassette guides to escape to the outside of the cassette storage section. are doing.

D Problems to be Solved by the Invention However, in the prior application, since the center of the large and small cassettes is positioned above the center of the cassette storage section,
Large and small cassettes cannot be inserted into the cassette storage unit with one side aligned. Therefore, the numbers and recorded contents of the large and small cassettes are displayed as barcodes on one side of these large and small cassettes, and the barcodes of the large and small cassettes are read by a barcode reader placed on one side of the cassette storage section. If configured to be read in common, the barcode reader can easily and accurately read the barcode on the side of the large cassette by bringing it close, but the barcode on the side of the small cassette cannot be read easily and accurately. There was a problem in that the code reader was placed far away, making reading difficult.

In addition, a barcode reader dedicated to small cassettes is placed in a position close to the side of the small cassette within the cassette storage compartment, and when a large cassette is inserted, this barcode reader dedicated to small cassettes is moved to the outside of the cassette storage compartment. Although it is conceivable to configure it like this, there is a problem that the structure becomes complicated.

Furthermore, in the prior application, when inserting a small cassette into the cassette storage section, the small cassette with a small width is inserted from the center of a large horizontally long cassette insertion slot formed to match the width of the large cassette. The problem is that the small cassette must be inserted between a pair of small cassette guides, making it difficult to insert the small cassette easily.

Furthermore, in the prior application, since a pair of small cassette guides and a small cassette guide drive mechanism were provided to drive them, the number of parts was large, the structure was complex, the number of assembly steps was large, and costs were high. was there.

Claim 1 of the present invention is a large and small cassette that can be inserted with one side of the large cassette and the small cassette aligned when selectively inserting the large cassette and the small cassette into the cassette storage section. The purpose is to provide a dual-purpose storage shelf.

Claim 2 of the present invention provides a storage shelf for both large and small cassettes, which allows positioning of small cassettes using one small cassette guide when selectively inserting and positioning large and small cassettes in the cassette storage section. is intended to provide.

E.
