A plurality of trays (T) are set in a disk package loaded into a disk device, and different types of disks are rested on the trays (T). Identification means (30) giving information about the type of a disk is provided on a hook (T7) of each of the trays (7), and detecting means (32) for detecting the information given by the identification means (30) is provided on a drawing lever (18) for drawing out the tray. When the disk package is loaded into the disk device, the types of the disks on the trays (T) can be discriminated by moving and positioning the drawing lever (18) to face the hooks (T7) of the trays (T) successively.
摘要:
Conventional disc units each involve the problem that a new disc must be inserted into the disc unit after a disc already present in the disc unit is ejected and that therefore it takes time for disc replacement. In the disc unit of the present invention, to solve the above-mentioned problem, a new second disc which has been inserted into the disc unit through an insertion opening is carried from an insertion area to a disc driving section by a conveying means. On the other hand, a first disc already present in the disc unit prior to insertion of the second disc is ejected from an ejection area to the exterior of the disc unit by both first and second ejection members. The time required for disc replacement can be shortened by performing the disc inserting operation by the conveying means and the disc ejecting operation by the first and second ejection members both in a simultaneous manner.

A transmission gear is comprised of a fitting portion of an upper toothed wheel being fit with a fitting portion of a lower toothed wheel so that both are axially movable. Accordingly, even in the event that a lid plate which has a disk introducing mechanism and a clamping chassis which has a clamping mechanism ascend or descend, certain power can be transmitted to a large gear (first gear) and a rotating cam (second gear) in a sure manner. Thus, the disk introducing mechanism and the disk discharging mechanism can both be driven with a single simple power transmitting mechanism. Also, the disk introducing operation and the disk discharging operation can be performed in a parallel manner, thereby reducing the amount of time required to exchange disks.
