Description

[Detailed Description of the Invention] The industrial application minute barometer is installed in a disc autochanger such as a compact disc (CD), and loads a disc from a disc magazine into a player, and ejects the disc from the player to the disc magazine. Regarding equipment.

2. Description of the Related Art Conventionally, disc autochangers have been known that take out one disc from a magazine containing a plurality of discs and automatically supply it to a player. This type of autochanger incorporates a magazine transfer mechanism that transfers and fixes the magazine to a predetermined position. A disk is taken out from a magazine fixed at a predetermined position by a disk ejecting mechanism of a loading/unloading device, conveyed to above a playback position by a disk transport mechanism, and then lowered to the playback position by a disk lowering mechanism and placed there. Then, the playback (performance) operation begins. After playback, the disc is raised above the playback position and then ejected toward the magazine.

Problems to be Solved by the Invention In the conventional device described above, after ejecting a disk toward a magazine, when the magazine is transferred to a predetermined position according to a program or when the magazine is transferred for ejection, The transfer operation may begin before the disk is properly returned to the magazine. In this case, the disk would be transferred with the disk protruding from the magazine, which could result in damage to the disk. If the disc is old and has scratches on its outer periphery, the disc may not slide smoothly and will not fit into the magazine securely, making accidents like this more likely.

Fix the disk passage opening of the magazine M in a fixed position.

This results in the state shown in FIG. 1(a).

When the position of the magazine M is fixed, the loading motor 1 rotates, and its rotation is caused by the rotation of the worm 2 → worm wheel 3 → reduction gear train 4 → 5 → 6 → gear 7 - gear 8 - i11i
The disc transport rubber roller 40 is rotated by the transmission as follows: speed gear train 9→lO→gear 15. Driven rubber roller 4L4J
It rotates due to friction. Furthermore, the rotation from the gear 8 is transmitted to the reduction gear train 11-112-gear 14a. Although it is rotating, the second clutch spring 14b slips and does not rotate.

Here, when the solenoid 20 operates, the plunger 21 rotates the link lever 23. Then, the hanging bin 23a
is separated from the stopper protrusion 14e, the intermittent cam gear 1
4 receives the rotation from the gear 14a via the clutch spring 14b, and the rotating 6 intermittent cam gear 14 rotates until the stopper projection 14f engages with the engagement pin 23a.9 When the intermittent cam gear 14 rotates a little, the intermittent cam gear 14 rotates. 1
4 meshes with a small gear 12a coaxial with the gear 12 and rotates under the drive. Therefore, the disk push lever 2
Since the cam roller L4d of the intermittent cam gear 14, which is engaged with the cam hole 27a of No. 7, rotates, the disk push lever 27 is pushed in the direction of arrow X against the bias of the spring 25. Then, the folded end 27b of the disk push-out lever 27 pushes the disk lever 153 of the disk magazine M, and the disk D is pushed out in the x8 direction by its rotational force.

The disk D is further pushed out, and eventually gets caught in the nip between the rotating disk conveyance rubber roller 40 and driven rubber roller 41 and begins to be conveyed.

This results in the state shown in FIG. 1(b).

Furthermore, the disk D is conveyed by the disk conveying rubber roller 40 and the driven rubber roller 41, and eventually rides on the rubber roller 95 and is conveyed above the playback position.

This results in the state shown in FIG. 1(C).

When this state is detected, the suction of the solenoid 2o is released. Then, since the link lever 23 returns, the bin 79b of the gear lock 79 also returns, and the gear lever 107 moves to the bin 7.
9a is disengaged. Therefore, friction felt 1
The gear lever 107 rotates due to the friction of 03, the gear 18 engages with the rack plate 19, and the gear 18 engages with the rack plate 19.
, the feeder arm lock lever 29 and the rubber roller 95 rotate clockwise together with the gear mounting plate 97.

On the other hand, the rotation of the gear mounting plate 97 causes the bin 97a to rotate the relay lever 102 counterclockwise. Therefore, from the regulation lever 85a to the bin 102a of the relay lever 102.
Since the disc is removed, the clamp arm 84 is pulled by the spring force and clamps the received disc in the player 85. When this is detected, the loading motor 1 stops.

As a result of the above, the disc D is placed at the playback position. That is, the state is shown in FIG. 1(d).

In this state, playback (performance) is performed by the player 85. When the reserved playback ends or the eject button is pressed, the ejecting operation begins.

In the ejecting operation, the loading motor 1 is started in reverse. A gear 18 meshing with the rack plate 19 is rotated by the drive of a gear train from the loading motor 1 and moves up along the rack plate 19. Therefore, the feeder arm lock lever 29 and the rubber roller 95 rotate counterclockwise together with the gear mounting plate 97. On the other hand, the rotation of the gear mounting plate 97 causes the bin 97a to rotate the relay lever 102 clockwise. Therefore, the regulation lever 85a is pushed by the bin 102a of the relay lever 102, and the clamp arm 84 is raised. As a result, the disc rises. When the rubber roller 95 rotates upward and comes into contact with the disk, the disk is ejected toward the disk conveying rubber roller 40 and the driven rubber roller 41. The disk is eventually added to the disk conveying rubber roller 40 and the driven rubber roller 41. It is ejected and stored in the magazine M. A disk suction mechanism using a leaf spring is attached to the magazine M, and when the disk passes about 273 times through the passage opening, the disk is automatically sucked into the innermost part of the magazine.

When the passage of this disk is detected photoelectrically, solenoid 2
0 again. Then, since blocking of the gear connecting plate 34 by the stopper lever 28 is excluded, the rotational force of the reduction gear 9 is transmitted by the friction of the friction spring 33, the gear connecting plate 34 rotates, and the gear 13 meshes with the spur gear 58a.
The rotation of the loading motor 1 passes through the gear train, reduction gear 9 → gear 13 → spur gear 58a → bevel binion 58b
This is transmitted and the bevel gear 53 rotates.

Then, since the cam roller 52 rotates, the guide elongated hole 48
b, and the swinging arm 48 swings left and right. At that time, the cam roller 52 moves to the cam surface 50a of the cam plate 50.
, the swing arm 48 moves up and down. Therefore, the carriage 63 slides left and right along the guide shaft 62, while the joint plate 61 moves up and down, so the push roller 65 descends only when it crosses in front of the disk transport rubber roller 40 and the driven rubber roller 41. ing.

The disk is completely inserted into the magazine by the disk ejection operation and disk suction operation described above.

Effects of the Invention According to the present invention, it is possible to realize a loading/unloading device for a disc autochanger that can reliably store discs in a magazine despite having a small number of parts and does not damage the discs.
