Abstract

PURPOSE:To surely operate a device with a small number of parts and to eliminate a shock sound to extend the life by releasing control by operating a solenoid to connect a first or second clutch gear to a driving system. CONSTITUTION:When a disk taking-out mechanism is to be operated, a solenoid 20 is operated to release the control and a first clutch gear 14 is connected to driving systems 6 to 8, and the operation of the disk taking-out mechanism is started. When the solenoid 20 is operated to release the control, a second clutch gear 14a is connected to driving systems 6 to 8 and 16, and the operation of a disk lowering mechanism is started. Since these operations are started by not engaging gears with driving systems with a spring force but engaging clutches with them, operations are surely and smoothly performed. Thus, a loading/ejecting device for a disk autochanger is obtained which is surely operated with a small number of parts and is free from the shock sound and has a long life.

FIG. 3 is an external view of an embodiment of a compatible magazine M suitable for use in the loading/unloading device of the disc autochanger, in which (a) is a front view, (b) is a top view,
(c) is a side view, and (d) is a bottom view.

In these figures, 150 is a casing with open bottom and front surfaces, 151 is a bottom plate that closes the opening of the casing 150, and this bottom plate 151 is attached to the casing 150 with screws. Reference numerals 152a and 152b denote a plurality of disk guide plates stacked on top of the bottom plate 151 inside the housing 150, with a spacer section on the side and a gap between each disk guide plate to ensure disk storage space.

Disc guide plate 15 of rotating lever 153
When the rotary lever 153 corresponding to the disc storage space formed by 2B is rotated, the single CD disc stored therein is pushed and ejected from the front opening of the housing 150.

In the above device, when a magazine containing disks is placed on the elevator decorative board 111, the elevator switch attached to the elevator base 126 is pressed and the elevator motor 141 rotates. The rotation is worm 144 → ohm wheel 130 → gear 130a
→ Relay gear 146a-e Relay gear 145 → Relay gear 14
6b.

Relay gear l 46c → elevator gear 128a.

128b and 128c, and the feed screw rod 127
a, 127b and 127C rotate.

Therefore, the elevator access 126 is the elevator decorative panel 1.
11, and at the lowest position, it hits a limit switch and the elevator motor 141 stops. From that position, the elevator motor 141 reverses, and the elevator base 126 rises together with the elevator decorative plate Ill.
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-I5 → 6-1 gear 7 - gear 8 → reduction gear train 9-10 → gear 15 As a result, the disk transport rubber roller 40 rotates. The driven rubber roller 41 rotates as a result of friction. Furthermore, rotation is transmitted from the gear 8 to the reduction gear train 11-12→gear 14a. However, since the intermittent cam gear 14 engages the engagement pin 23a of the link lever 23 with the stopper protrusion 14e, the coaxial gear 1
Although clutch spring 4a is rotating, 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
2 intermittent cam gear 1 because it separates from the stopper protrusion 14e.
4 is rotated by the rotation from the gear 14a being transmitted through the clutch spring 14b. The intermittent cam gear 14 rotates until the stopper protrusion 14f engages with the engagement pin 23a. When the intermittent cam gear 14 rotates a little, the intermittent cam gear 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 14d 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 the arrow x1 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 x2 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, the link lever 23 returns, so the bin 79b6 of the gear lock 79 returns, and the gear lever 107 moves 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.8 As a result, the bin 102a of the relay lever 102 is removed from the regulation lever 85a, and the clamp arm 84 is pulled by the spring force. Fallen,
Insert the disc into the player 85,
Upon detecting this, 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, the player 85 reproduces (plays) the music. When the scheduled playback ends or the eject button is pressed, the ejection operation begins.

In the ejection 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, gear mounting plate 9
7, the bin 97a rotates the relay lever 102 in the clockwise direction. Therefore, the regulation lever 85a is pushed by the bottle l02a of the relay lever 1.02, and the clamp arm 84 is raised. As a result, the disc rises. When the rubber roller 95 rotates seven times 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, is ejected, and is housed in the magazine M. Magazine M is equipped with a disk suction mechanism using a leaf spring, and the disk passes through the passage port at 273.
Once the disc has passed the limit, the disc will be automatically sucked into the magazine to its deepest position.

If the passage of this disk is detected photoelectrically, the Tsuraid 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 l 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 the cam 50 of the cam plate 50.
Since it is in contact with point a, the swinging arm 48 moves two degrees.

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. There is.

In the unlikely event that the above-mentioned disc drive-out operation or disc suction operation is insufficient, the operation of the push roller 65 will ensure that the disc is completely inserted into the magazine.

ADVANTAGES OF THE INVENTION According to the present invention, it is possible to realize a loading/unloading device for a disc autochanger that has a small number of parts, operates reliably, is free from impact, and has a long life.
