The bottom plate 130 and the first side plate 110 define an extension space S1, and the extension space S1 is connected to each storage space S. When the cassette is normally stored in the storage space S, the cassette is located outside the extension space S1. The utility model discloses borrow by the configuration in extra extension space S1, when the cassette box got into extension space S1, can let operating personnel take the cassette box better and more fast.

Specifically, the first bottom surface 131 is disposed at a lower level than the second bottom surface 132. Therefore, the extending space S1 is defined by a horizontal plane (shown by a dotted line) extending from the first bottom surface 131, the first side plate 110 and the second bottom surface 132 toward the first side plate 110. In one embodiment, the base plate 130 may further include a bottom connection part 133, and the bottom connection part 133 is formed in a slope to connect between the first bottom surface 131 and the second bottom surface 132 at different upper and lower levels.

The outer plate 122 is farther from the first side plate 110 than the second side barrier 121, so that the shortest distance L between the vertical surface of the first side barrier 111 and the vertical surface of the second side barrier 121 is smaller than the shortest distance L between the vertical surface of the first side barrier 111 and the vertical surface of the outer plate 122. Therefore, the amplification space S2 is defined by the second bottom surface 132, the outer plate 122, and a vertical surface (shown by a dotted line) of the second side stop 121 facing the second bottom surface 132. In an embodiment, the second side plate 120 may further include a side connection portion 123, and the side connection portion 123 is formed in a slope to connect the second side blocking portion 121 and the outer side plate 122 which are located on different vertical surfaces.

Referring to fig. 5A and 5B, in one embodiment, each cassette 150 may further include identification information 151, such as, but not limited to, a one-dimensional bar Code (barcode) or a two-dimensional bar Code (QR Code). The height of the first side plate 110 is less than or equal to the height of the second side plate 120, so that the identification information of each cassette 150 can be exposed from above the first side plate 110. For example, the identification information 151 is disposed on the outer surface of the cassette box 150 corresponding to the upper side of the first side barrier 111, so that the identification information 151 is not blocked by the first side barrier 111. Each identification information 151 records information of a disc placed in the respective cartridge 150. Therefore, the operator can confirm the cassette 150 to be taken by only scanning the identification information 151. In addition, in an embodiment, a scanner may be added to the servo mechanism a2 of fig. 2A, and located near the disc changer 6, to record the information of the replaced cassette 150 in real time.

The utility model provides a store cabinet and servo framework provides an extra extension space to the parking space of each cassette box. The operator can press one corner of the cassette box to make the cassette box enter the extending space, thereby staggering the position of the cassette box and the rest of the cassette box, so that the operator can take the cassette box better and more quickly. In addition, the storage cabinet can be installed and expanded by the operator according to different servo architectures, so that the operator can have more flexibility.

In summary, although the present invention has been described with reference to the above embodiments, the invention is not limited thereto. The utility model can be changed and modified by the technicians in the technical field without departing from the spirit and scope of the utility model.
