DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recorded medium reproducing apparatus having a recorded medium exchanger, and more particularly to display means for displaying information of a presence/absence of a recorded medium in a recorded medium stocker of a recorded medium reproducing apparatus which can exchange a recorded medium even during the reproduction of another recorded medium.
RELATED BACKGROUND ART
As a conventional recorded medium reproducing apparatus having a recorded medium exchanger, a disk reproducing apparatus such as shown in FIG. 26 disclosed in Japanese Patent Laid-open Publication No. 4-38673 is known in which a stocker houses a plurality of carriers each capable of placing a disk thereon and is raised or lowered by stocker transport means to a height at which a desired carrier is pulled out by a tray. Namely, the stocker is moved by a distance corresponding to the number of shelves for housing carriers.
The tray is transported between a load position shown in FIGS. 26(a) and 26(b) and an eject position shown in FIGS. 26(c). As shown in FIG. 26(a), the carrier having a desired disk placed thereon is pulled out on the tray at the load position, and the disk is clamped by clamping means to reproduce the disk as shown in FIG. 26(b).
As the tray with the carrier moves from the position shown in FIG. 26(a) to the position shown in FIG. 26(c), the carrier on the tray is exposed to the outside of the apparatus housing. In this state, the disk on the carrier is exchanged or a new disk is placed on the carrier. As the tray with the carrier moves from the position shown in FIG. 26(c) to the position shown in FIG. 26(a) and the carrier on the tray is moved back to the stocker, the disk can be exchanged or a new disk can be added to the apparatus. This disk reproducing apparatus is advantageous over a conventional disk reproducing apparatus with an exchanger in that a disk magazine is not used. The disk magazine is expensive, and if it is dismounted from the apparatus and placed at a different position, it takes some time to locate this disk magazine. This is inconvenient to use.
However, this disk reproducing apparatus disclosed in the above-described Japanese Patent Laid-open Publication No. 4-38673 has only one means for pulling a carrier out of the stocker. Therefore, a disk in the stocker cannot be exchanged during the reproduction when the carrier is at the position of reproducing means.
FIG. 27 shows a disk reproducing apparatus disclosed in Japanese Patent Laid-open Publication No. 3-71432 which can exchange a disk even during the reproduction of another disk. This disk reproducing apparatus is of a so-called carousel type. A tray 126 shown in FIG. 27 is driven by a motor and moved into and out of a reproducing apparatus main body 128 in the arrow direction A. A rotary table 130 is rotatively mounted on the tray to be driven by a motor in the arrow direction B. A plurality of disk holders 134 are formed on the rotary table 130 so as to hold disks 101 around the rotation center 132. Each disk holder 134 has a 12 cm CD groove 134a and an 8 cm CD groove 134b. The bottom of the disk holder 134 is inclined in the rotation direction so as to hold a disk in a slanted state.
An opening 136 is formed in the disk holder 134 in the radial direction of the rotary table 130 so as to insert therethrough a turn table and a reproduction head. An opening 138 is formed in the tray 126 at the center back end thereof so as to communicate with the opening 136 of each disk holder 134. During the reproduction, the turntable and reproduction head are inserted into these openings 138 and 136.
A subsidiary chassis 142 is supported under the tray at the center back of a mechanical chassis 140 of the reproducing apparatus main body 128 by a pivot shaft 144 which is pivoted in the arrow direction C by a motor. The subsidiary chassis 142 is mounted with the turntable 172 and an unrepresented reproduction head. A disk clamper 1466 is fixedly mounted on the mechanical chassis, facing the t
