Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a cassette selection device for selecting and taking out an arbitrary tape from a device storing a plurality of tape cassettes for a VTR to a video deck, for example. It is something.

(b) Prior art Generally, this type of cassette selection device is installed in hotels and other facilities for viewing by hotel users.
Since a plurality of VCR tape cassettes, for example six rolls, are housed in a completely sealed casing without a door, the tape cassettes in the device cannot be replaced with tape cassettes held by hotel guests.

(c) Problems to be solved by the invention As described above, the conventional apparatus had the disadvantage that a separate tape cassette could not be inserted from outside the apparatus. In other words, since a user's own tape cassette cannot be inserted into a conventional device, it would be impossible for a hotel user, for example, to attach his or her own tape cassette for an educational seminar and watch the program. This is the translation.

(d) Means for solving the problem Therefore, the technical problem of the present invention is to provide a closed casing with a door that can be opened and closed so that any one of the tape cassettes can be taken out and any one of these tape cassettes can be removed. A tape cassette held by a hotel user is stored in the space by emptying the cassette space, and the door is locked while the internal mechanism is operating, and the door is opened only when the internal mechanism is stopped. It is in.

The technical means of the present invention for solving this technical problem includes a cassette shelf having a plurality of cassette storage sections for storing cassettes, a moving mechanism for moving the cassette shelf, and a casing for sealing the cassette shelf and the moving mechanism. and a door that can be opened and closed is disposed in a portion of the sealed casing facing one of the cassette storage sections of the cassette shelf, and further includes a door lock lever that locks the opening operation of the door, and a door lock lever that locks the opening operation of the door, and a door lock lever that locks the opening operation of the door; A lock release plate is provided which interlocks with the door lock lever to release the door lock lever, and locks the door while the cassette shelf is moving, and also ensures that a predetermined cassette storage section and the door face each other, and that the cassette shelf cannot be moved. When it stopped,
The lock release plate is configured to release the door lock lever.

(E) Effect According to this technical means, only when a predetermined cassette storage section and the door face each other and the movement of the cassette shelf stops, the door lock lever is released by the lock release plate and the door is opened. Since the door can be opened during normal cassette selection operations, the door remains closed, preventing injury to the user and mechanical or electrical equipment trouble due to forced replacement of the cassette. It is safe because it does not occur, and when the door is opened, the user can attach the tape cassette he or she has on hand through the opened door.
