Abstract

PURPOSE:To handle simultaeously plural disks, and to reproduce them successively, by containing plural holding frames for holding a disk, in a container case, and drawing out, separating and returning one piece of them. CONSTITUTION:Five disks 4 are held by holding frames 5, respectively, and are contained in a containing chamber of a case 3. A disk selecting mechanism 9 consisting of a decelerating gear 12, a turning cam 13 and an L-shaped lever 14 is provided on a reproducing device, and also a drawing out, returning and separatint mechanism 16 of the holding frame 5 is driven by a motor 25 through a wire 17. The disk 4 to be reproduced is moved to a reproducing face position P by use of the mechanism 9, a separating lever of the mechanism 16 is fitted into a recessed part of the holding frame 5, the holding frame 5 is drawn out to a reproducing position Q, and thereafter, the clamped by a spindle 23 and a clamper 22, and reproducing is executed. After it is ended, said operation is reversed, and the holding frame 5 is returned to the case 3. Therefore, plura disks can be handled simultaneously and can be reproduced successively.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc-shaped information recording medium reproducing device, in which a plurality of disc-shaped information media are held in respective holding frames by a cage.
Case J for disc-shaped information recording media: Repeat the pull-out operation N1 to remove multiple discs with a distance of 1 μm between the trays. It is an object of the present invention to provide a 4F device for a disc-shaped information recording medium, which is configured to sequentially reproduce a circle Q1-shaped information recording medium in the order of 10 grams.

In the conventional video disc playback system or the PCM Δ-disk i1741 system, the disc cartridge has a structure in which one disc is stored in the disc side mount, and the playback device side holds the disc cartridge. Insert 1 (remove the disc to play it, insert it)
It was installed inside and the structure was such that it could be played. For this reason, with this conventional replay method, playback of Ij and discs is limited to one disc, and if you wish to play multiple discs, each time the playback of one disc is finished, The lowering operation is required to replace the disk. On the other hand, a playback device that sequentially plays multiple discs in program order may be limited to A-Gay A1 No. However, in the case of the previous step, one seed 1 is placed before the second η
It is necessary to take out the record tray 17/7'' and stack it on the spindle 1- (insert it, and after playback is finished, put it back in the 1-record tray A7). In addition to being troublesome to handle, there is also a risk that the recording surface may get dirty or scratched during handling.
The disadvantage is that the playback order is limited to the stacked order and the playback order cannot be freely set. In addition, in the case of late arrival, multiple 1]-do discs can be played in the order of 1-1 crumbs, but the 1-do discs are bare and easily damaged. In addition, the mechanism itself was popular, the multiple bells made a roaring sound, the mechanism was expensive, and it was unsuitable as a general cattle equipment.

The present invention eliminates the above-mentioned drawbacks, and each embodiment thereof will be explained below along with the drawings.

FIG. 1 shows a disc playback device 1 according to the present invention and disc cars 1 to 2 that can be used therefor.

Roughly speaking, the disc cars 1 to 2 are lined up in the 19/j direction with, for example, five discs 4 held in a holding frame 5 in a case 3 with a frontage. It is of a structure that is housed in. Each holding frame 5 (disc 4) is housed in a state in which it can be pulled out from each storage chamber which is partitioned from each other and assigned an address within the case 3. The details of the disk cars 1 to 2 will be described later.

To play a disc, pull the cover 6 on the front mill panel side of the disk reproducing device 1 toward you to open it (), and place the disc car 1 to the cartridge 2 as shown in Figure 1.
(January Big) Insert the disc car 1 into the mounting plate through the 10-face plate 1] in an attitude facing toward the knob device, insert the disc 1 vertically to the frame-shaped disk car 1 edge holding base 70, and close the cover 6. . As a result, the five disks are vertically aligned parallel to the panels 1 to 1 of the C assembly 1, and are lined up in the depth direction of the apparatus. Next, operate the C1 Tsukaku r118, set the disc number and program number, and set the playback order. is first played''! 1 of the disk specified as b (e.g. number 2 [1 of 1' (suf)
Start playing the cover motion.

As shown in FIG. 2 (1'J,''), first, the mechanism 9 for selecting the disc to be played is activated, and the support base 10 is moved by the arrows X+,X,! :/'J moves in the direction. The disk cartridge 2 was held within the holding base 7":・Support l\
-Move toward the depth of the device to
The disc 1 stops with the disc 1 facing the disc playback surface position (holding frame pull-out position).

Self-tasting j! The selection mechanism 9 includes a motor 11 and a deceleration key 1.
The support base 10 is rotated in accordance with the rotation of the rotation force l\13 by the rotation force l\13 and the rotation force l\13.

Detecting the moving position of the disk cartridge 2 by detecting the 1-shaped lever 1/I that moves in two directions and the edge of the support base 10, detecting the position where the disk cartridge 2 is placed corresponding to the disk number. Shin1j15'-1"・15-5 and J Korinaru.

Moving in one direction, the disk 4 is reflapped onto the spindle 23 and the clamper 22.

Subsequently, the holding frame 5 is separated in the disk radial direction by the base silk solid body 16, and the disk 4 is held (・11!)
First, the holding state is released and the state is such that it can rotate.

- When the shifter 41 is completed, the device operates in the reverse order as described above. After the rotation of the beaten disk 4 is stopped, the holding frame 5-C is released, and moved in the direction of arrow Y2, both the fJIU and f urine holding frames 5 are stored in the case 3, and jz It(' .Device City 1 then moves on to the operation of reproducing the disc. The five discs in one edge 2 are sequentially reproduced in the order of 1<-, fr, +grams.

Next, the disk cartridge 2 will be explained in detail with reference to FIGS. 3 to 7.

As shown in FIG. 3, the disc cartridge 2 is held in the case 3 with five discs 4 held in the holding frame 5. ,? I will pay it.

1- As described above, the disc-shaped information recording medium reproducing device fin according to the present invention has a 110n-shaped information recording medium with a substantially concave t-shaped outer periphery.
The disc-shaped information recording medium car 1 to the disc-shaped information recording medium car 1 to which the ridge is attached is stored in a drawable state so that the disc holding frame is stored in the coop so that it can be pulled out. Move the J-tridges (attached to the cartridge mounting section and the car 1 to ridge H-8) to the disk holding frame alignment position 11 (, The disk holding frame in the middle drawer position of the SFC 1 helicopter is pulled out together with the disc-shaped information recording body held by the case J, and after the playback is completed, the disc 1 is converted into a disk. , Return and store the r frame in the case J, Isuku storage Fi frame drawer/return 7 JI storage means and the disk holding frame pulled out from the case Release the hold on the recording medium and rotate the recording medium. However, after the first completion, the disk holding frame is set to hold the recording medium.
- By simply installing and covering the disc cartridge, you can play the multiple recording media in this disc cartridge in program order, and if you want to play another disc, you can play the discs from disc car 1 to It is easy to handle with IJ, and the configuration can be made simple and compact, but the risk of scratches on the recording medium can be minimized, such as Kara A Tsuno device, background playback. It can be used not only for commercial equipment such as equipment but also for consumer equipment.
How can -B be realized and have features such as being applicable to a wide range of applications? Ill.
