Abstract

PURPOSE:To shorten the changing time of a disk by arranging oppositely respectively independently a conveying means to supply a disk and a conveying means to store the disk. CONSTITUTION:At both sides of a disk stocker 1, a guiding rail 3 of a disk supplying carrier 2 and a guiding rail 5 of a disk storing carrier 4 are arranged, and by arranging a reproducing device 6 between respective guiding rails 3 and 5, an auto changer is constituted. Thus, the auto changer with a very short disk changing time can be realized so that the removing and supplying of the disk can be executed approximately without a time difference.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic disc playing device (hereinafter referred to as an autochanger).

BACKGROUND OF THE INVENTION In recent years, many automatic disk changers have been seen that use non-contact, large-capacity optical disks as information storage media, store a large number of these disks, take them out and replace them one after another, and reproduce the information.

Conventionally, this type of autochanger includes a stocker that stores a plurality of discs, one or more disc playback devices, and a disc selection means that supplies discs from the stocker to the playback device and stores them in the stocker. There are many things that are configured. These series of operations are performed, for example, as follows. When a command is issued to place a person's disk on the playback device, the disk selection means selects the person's disk from the stocker and places it on the playback device. Next, when a command is issued to place disk E on the playback device, the disk selection means first takes out the person's disk from the playback device, transfers it to the stocker, and stores it in the person's position. After this, the second disc is selected and placed on the playback device. Generally, such operations are repeated.

Problems to be Solved by the Invention However, in such conventional autochangers, it takes a long time to change the disk (i.e.,
Time required for the disc on the playback device to stop, time to store this disc in the stocker, time to feed a new disc from the stocker to the playback device, and time for the disc to reach the specified rotation speed on the playback device. ).

In view of the above-mentioned problems, the present invention aims to provide an autochanger that requires an extremely short disk exchange time.

Means for Solving the Problems In order to solve the above-mentioned problems, in the present invention, the transport means for supplying discs and the transport means for storing discs are arranged oppositely and independently of each other through the playback device. The configuration is such that the

Operation With the above-described structure, the disk feeding and storing operations can be performed independently, and the disk can be fed after being taken out, thereby realizing an autochanger that can significantly shorten the disk changing time.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram in one embodiment of the present invention,
On both sides of the disc stocker 1, guide rails 3 of the disc supply carrier 2 and guide rails 6 of the disc storage carrier 4 are arranged.

An autochanger is constructed by disposing a reproduction device 6 between each of the guide rails 3.6.

FIG. 2 shows the disc tray 7 used in this autochanger, in which 9 is a recess with a 1° long hole;
11 is a notch for positioning.

The disc 8 is stored in the recess 9 together with the disc tray 7 in the disc stocker 1.

FIG. 3 shows the details of the playback device 6, the disk supply, and the storage carrier 2.4 (the storage carrier is not shown). Additionally, an arm 12 for supplying to the reproducing device 6 is provided. This arm 12
The disk tray 7 taken out from the disk stocker 1 is mounted on the disk supply carrier 2 as shown in the figure. The playback device 6 includes a tray guide 13° and a clamp arm 14. Turntable 16. A pickup 16 is provided, and the tray guide 13 and clamp arm 14 fit into the cam groove 1 of the cam plate 17 provided on both sides.
8, and is configured to be lowered in the direction b by the movement of the cam plate 17 in the direction a. Although not shown here, the disc storage carrier 4 has exactly the same configuration as the disc supply carrier 2, and is compatible with the playback device 6.
It is constructed symmetrically through the

4A to 4C show the operation of supplying, reproducing, and storing the disk 8, and the operation will be described below with reference to FIGS. 1 to 3.

In response to a user's command, the disc supply carrier 2 enters the state shown in FIG. 4A in which a predetermined disc 8 is stored in the disc stocker 1, the disc tray 7 is taken out and placed, and the disc tray 7 is stopped at a predetermined position of the playback device 6. From this state, the arm 12 moves the disc tray 7 against the tray guide 13.
Insert it to the position determined by the notch 11. After this, the cam plate 17 moves in the direction a, and the tray guide 13 moves in the direction b.
The disc 8 is fixed on the turntable 16 by the clamp arm 14, and the pickup 16 enters the 1° elongated hole of the disc tray 7, and the turntable 16 rotates to perform a playback operation. When the playback of the 0-disc 8, which is in the state shown in FIG. The arm 12' is in the state shown in FIG. 4C, with the disc tray 7 and the playback device 6 taken out. Thereafter, the disc storage carrier 4 stores the disc tray 7 in its original location in the disc stocker 1.

A series of operations have been described above, but when a disk replacement command is issued during playback, the operations proceed in the order of B -> H -> B in FIG. 4. In addition, in the case where the replacement time is the shortest, the states A and C in Figure 4 will be at the same time (that is, when the disc tray 7 is pulled out by the storage carrier 4, a new disc tray 7 will be set by the supply carrier 2). (waiting at a possible location).

Although this embodiment has been described using a disk tray, it goes without saying that it can also be constructed using a disk cartridge or a single disk.

Further, by adding a recording function to the playback device used in this embodiment, the present invention can also be used as an automatic recording device.

Effects of the Invention As described above, in the present invention, by providing a playback device in which discs can be inserted and ejected from both sides, and disc supply and storage carriers provided on both sides, it is possible to almost eliminate disc ejection and supply. It is possible to realize an autochanger that can be performed without any time lag and has an extremely short disk exchange time. For example, by applying it to a large-scale disk library, the user's waiting time will be extremely short and a great effect can be obtained. is 0
