Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a disc playback device, and more particularly to a disc playback device equipped with a so-called changer function that can selectively play a plurality of discs.

(Prior Art) Currently, a plurality of optically readable discs are stored in a stocker that is removably attached to a disc playback device, and this stocker is attached to the disc playback device to read a plurality of discs. So-called changer-type players that selectively play back are commercially available. In this player, when playing a disc that is not stored in the stocker, first remove the stocker from the player and store the disc to be played in the part of the stocker where no disc is installed, or if the disc is not stored in the stocker. Since it is necessary to remove one disc from the stocker, store the disc to be played in this area, and then attach the stocker to the player, there is a drawback in its operability.

In order to solve this drawback, Japanese Utility Model Application Publication No. 62-195257 discloses, in particular, an opening into which a removable stocker is inserted into the player, and a stocker t which is arranged in parallel with this opening and protrudes from the player. A player has been proposed that is equipped with a single-disc tray on which discs that are not stored are placed.

In this player, as shown in FIG. 13, a plurality of disks 5. ~5. The discs 5° placed on the tray 2 while stored in the player 1 are arranged vertically so that their rotational axes are coaxial, and the disc reproducing means 3 consisting of an optical head, turntable, etc. is connected to the stocker. 4 and the rear of tray 2. Further, the disc reproducing means 3 moves up and down in the direction of the arrow in the figure so as to be positioned behind the disc to be reproduced.

(Problem to be solved by the invention) In this case, because the disc playback means can be moved up and down on a disc where information is recorded on the order of microns, unavoidable backlash etc. due to the structure is caused. This will have a negative impact on accurate signal reading.

Further, in order to minimize this backlash, it is necessary to provide a special mechanism for removing the backlash in addition to the vertical mechanism of the disk reproducing means, which is disadvantageous in terms of cost.

Here, in the above-mentioned conventional example, the disc reproducing means 3
It is also possible to adopt a configuration in which a disc pulled out from the stocker 4 or the main tray 2 is moved up and down to the disc reproducing means 3 without moving the disc. However, all of them have the following drawbacks.

That is, when playing a disc that is not stored in the player 1, the disc 5° placed on the tray 2 is pulled into the player 1, and then the disc 5° on the tray 2 is placed on top of the disc playing means 3. After positioning, it is necessary to move the disc 5° and the disc reproducing means 3 relative to each other. These operations have the disadvantage that, for a player equipped with a stocker and capable of reproducing only a single disk, the operation of positioning the tray from the tray above the disk reproducing means 3 increases, and the operability thereof deteriorates.

(Measures to solve the problem) Place the disc on! ! 1 copy, disc playback I
In order to take the first position where the disc is stored in Ia and the second position where the disc is placed on or taken out from the mounting part, the disc is placed on the mounting part. a tray that is movable with respect to the apparatus in a direction parallel to the recording surface of the disc placed on the tray; A reproducible disc reproducing means, a stocker disposed in the apparatus, capable of storing a plurality of discs so that their rotational axes are coaxial, and movable in a direction perpendicular to the recording surface of the stored discs; , a disk moving means capable of moving the disk in a direction parallel to the recording surface of the disk between the loading section at the ml position of the tray and the stocker.

(Function) When playing a disc that is not stored in the stocker,
A disk is placed on a disk mounting portion of a tray projected outside the device, and the disk is played back by a disk playback means arranged perpendicularly to the recording surface of the disk with the tray housed inside the device. In addition, when playing a desired disc among a plurality of discs stored in the stocker, the disc loading portion of the tray stored in the device is
The disk is moved from this stocker and played back by the disk playback means. Furthermore, when storing a disc in the stocker, the disc is placed on the disc mounting portion of a tray that protrudes outside the device, and the disc is moved horizontally relative to its recording surface while the tray is stored in the device. and store it in the stocker.

3. after moving it into the main tray 30 (Fig. 12 (
d)) The main tray 30 is made to protrude outside the player 1. In this state, a disc is placed on the sub-tray 23 (FIG. 12(e)), and after moving the main tray 30 inside the player 1, the sub-tray 23. stocker 20
(FIG. 12(f)), then move the stocker 20 a required distance above the main tray, and move the subtray 233 stored in the third stage of the stocker 20 to the main tray. A movable portion is brought into the tray 30 (FIG. 12 (9)).

By performing the above operations continuously, the sub tray 2
32-23. Store 5 discs in.

In the above embodiment, the control circuit 120 shown in FIG. 1 controls each drive source 121 to 12 so that the player 1 is always in the state shown in FIG. 12(a) in an initial state such as when the power is turned on.
5 is controlled. Therefore, when playing a disc that is not stored in the player 1, the main tray 3
It is only necessary to make the changer protrude from the player 1, and its responsiveness and operability are no different from those of a player that does not have a changer function. however,
When playing a disc stored in the stocker 20, the subtray 23. It is necessary to store the discs on the top stage of the stocker 20 and move the stocker 20 up and down, and then move the sub-tray on which the desired disc is placed into the main tray 30.

Therefore, if emphasis is placed on responsiveness and operability when playing the discs stored in the stocker 20, the control unit 120 controls each drive source so that the player 1 is always in the state shown in FIG. 12(b) in the initial state. 121 to 125 are controlled. In this case, when playing back a disc stored in the stocker 20, the first operation is to move the stocker 20 up and down, so that the response speed can be improved compared to the above embodiment.

In the above embodiment, the player 1 also has the subtray 23. It is controlled by the control circuit 120 so that it cannot be stored in the stocker 20 with a disk placed thereon. This consists of subtrays 23, -23. If you want to play a disc that is not stored in the player 1 with the main tray 30 stored in the main tray 30, the main tray 30 must be protruded from the player 1 with one of the subtrays on which the required disc is placed stored in the main tray 30. Because it has to be
This is because the operator is forced to replace the disk. That is, the subtray 23. A disc is placed only when playing a disc that is not stored in the player 1.

However, if emphasis is placed on the storage capacity of discs inside the player 1, it is also possible to place discs on all six sub-trays and store them in the stocker 20. In this case, when playing back a disc that is not stored in the stocker 20, if the stocker 201 contains a sub-tray with a disc placed on it and a sub-tray with no disc placed on it, the disc stored in the stocker 20 Among the subtrays, a subtray on which no disc is placed is detected by a required detection means, and after being stored in the main tray, it is made to protrude from the player 1. In addition, when all discs are placed on the sub-trays stored in the stocker 201, after storing any of the sub-trays in the main tray, the operator projects the sub-trays from the player 1 and replaces the discs. .

Further, in the above-described embodiment, the stocker 20 is arranged on the extension line of the main tray 30 in the moving direction, but the present invention is not limited to this, and when the main tray 30 is located inside the player 1, the main It is also possible to arrange it in a direction perpendicular to the moving direction of the tray 30.

Furthermore, it goes without saying that various embodiments are possible, such as the possibility of moving the disk between the stocker and the main tray by bringing the drive roller into direct contact with the disk without using a sub-tray.

(Effects of the Invention) As described above, according to the present invention, when playing a disc that is not stored inside the player, the playback mechanism is activated while the disc placed on the tray is stored in the player together with the tray. Because it is located at the bottom, it is possible for a player not equipped with a stocker to stock a plurality of discs inside the player without impairing its responsiveness and operability.

In addition, since the reproducing mechanism consisting of an optical head, turntable, etc. does not require a moving mechanism to move up and down with respect to the chassis, by adding a changer function, playback a! It is possible to adopt a configuration that does not have negative effects on the structure.

Furthermore, according to the present invention, the work of storing a plurality of discs inside the player is performed mechanically and does not involve the operator's hands, so that the work of storing a plurality of discs can be carried out without staining or scratching the discs. It is something.
