In such a case, the rack member 13 drives a pinion gear 14 and drives an operating lever clockwise via a gear part 15a simultaneously, then the operating part 15b presses the ridge of the disk A to push out it from a slit 4a to the outside of a jacket room 3.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a disc magazine suitable for use in an optical compact disc player.

(Background Art) Conventionally, in an optical compact disc player (hereinafter simply referred to as a CD player), a disc is placed on a tray, stored in a magazine or case, and the tray is moved onto a turntable. There is also a system in which the discs are stored individually in a magazine or case, and the discs are taken out individually and moved onto the turntable.

The former has the disadvantage that when a magazine is constructed by stacking multiple trays for an autochanger, the entire magazine becomes thicker, whereas the latter allows the magazine to be made smaller and thinner by omitting this tray. It has the advantage of being able to be transformed into

This invention belongs to the latter category, and in this case, it is designed to be as small as possible, and also to allow the disc to be reliably inserted and removed with a simple touch without staining or damaging the playing surface of the disc. It was naturally desirable to open the constructed magazine.

(Technical Section '8) An object of the present invention is to provide a disk magazine, particularly for a CD player with an autochanger, which has a configuration that fully satisfies the above-mentioned needs.

(Technical Means) - In order to achieve the above-mentioned technical problem, the present invention provides a storage chamber in which a disk is stored in the case body, and a mechanism that rotates the disk in the insertion/removal direction at the front and back of one side of the storage chamber. An operating lever and a holding lever are provided to move the operating lever and a holding lever, and an operating mechanism is provided to intermittently control the movement of the operating lever and the holding lever, and the operating portion thereof is protruded outside the case body, thereby allowing the disc to move into the storage chamber. When the disc is inserted, the operating lever and the holding lever rotate to measure the passage of the disc, and the holding lever lightly presses the inserted disc, and when the operating section is operated, the operating lever pushes the disc out. It consists of a disk magazine.

(Example) According to the drawings, in FIGS. 1 to 2 and 4, 1 is a case body, and this case body 1 has five plates between a lower plate 1a and an upper plate 1b. Six storage chambers 3.3.3e and φ are formed by partitioning with partition plates 2.2.2φ...
It is. A part of the front part and one side part of this case body 1 are open, and the front part has a slit plate with six slits 4a, 4a, 4a, and slits that become narrower from the center to both sides. 4 is attached, and each slit 4a, 4a, 4a...Φ is connected to each storage chamber 3.3.3...φ
It corresponds to A part of the open side surface of the case body 1 directly forms a notch 5, from which an operating portion 9d of an operating member 9 of an operating mechanism, which will be described later, protrudes.

Storage chamber 3.3.3 Lower i1a facing each other inside the fist φ fist
and the partition plate 2, between the partition plate 2.2, and between the partition plate 2 and the upper plate 1b, a pair of tapered protrusions 6.6 are provided near the center, each facing in the disk insertion direction. In addition, on both sides of each storage chamber 3.3.3, there is a length d? in the disk insertion direction, as shown in FIG. a
, 8a are provided. A pair of long and short disk holding members 7.8 are provided.

Each storage chamber 3.3.3 ha is equipped with a mechanism that receives and holds the disk and automatically sends it out. Since both have the same configuration, we will first explain the operating mechanism of one of them.

In particular, as shown in FIG. 3, reference numeral 9 denotes an operating member that is biased to move in one direction by a tension coil spring 10 and is slidable in the same direction as the disk insertion/removal direction. The operating portion 9a is made to protrude from the notch of the case body 1 as described above. This operating member 9
A cam pin 11 having a locking portion 11a at its tip is attached to the cam pin 11, and a cam portion 12 protrudes from the partition plate 2 in contact with the locking portion 11a of the cam pin 11. A rack member 13 is provided in the direction of movement of the operating member 9, with parts of the rack member 13 overlapping each other so as to be slidable in the same direction.
A pinion gear 14 is rotatably attached to the rack portion +3a of the rack member 13 by a pin 19 in mesh with the rack portion +3a of the rack member 13.

Next, an actuating lever 15 is an approximately arcuate planar member rotatably attached to the pinion gear 14 by a pin 16. A gear portion +5a provided on the side pivoted to the pin 16 is in mesh with another small gear 14a provided overlapping the pinion gear 14.

A holding lever 18 is rotatably attached to a front position on one side of the storage chamber 3 on the same plane as the operating lever 15 by means of a pin 17. As shown, it has a groove +8a into which the edge of the disk is inserted, and two pins 1 are inserted into this groove 18a.
9.20 is attached, and has a protrusion 18b that engages with a protrusion 9b provided on the operating member 9.

Next, to explain the operation, the mechanism in each storage chamber 3, 3, 3, etc. of the original music into which the disc is inserted is in the state shown in FIG. , the operating part +5b side at the tip is located approximately at the center of the storage chamber 3, and the rack member 13 is slid by the gear part 15a via the pinion gear 14 to the position (2) near the operating member 9. be. On the other hand, the holding lever 18 has a projection 18b.
is brought into contact with the protruding piece 9b of the operating member 9. Further, the operating member 9 is pulled by the tension coil spring 10 and is in the position (3).

Therefore, when the disk ■ is inserted into the storage chamber 3 from the slit 4a side, the disk ■ becomes the above-mentioned slit).
The shape of 4a allows the playing surface to be inserted without rubbing,
First, its edge is fitted into the tip of the groove 18a of the holding lever 18 and comes into contact with the pin 19. In this state, the holding lever 18 pulls the protrusion +8b and is in contact with the protrusion 9b of the operating member 9 which is being pulled by the coil spring 10 as described above, so it does not rotate and retract easily, and the disc ■ By applying a force in the insertion direction, the operating member 9 slides against the traction force of the tension coil spring 10.
13 is rotated and retracted clockwise to allow the disk A to pass through d and θ. During this passage, the other edge 1 of the disk A also fits into the length Iη7a provided on the holding member 7. The edge of the disk A (7) to be inserted further comes into contact with the pin 20 of the holding lever 18, pushes the holding member, and is inserted while rotating and retreating further clockwise.

At this time, the edge of disk A operates at the same time, and the operating part of 8-15! Press 5b to rotate it counterclockwise,
At this time, since the rotation of /<-15 is not prevented in any way, it rotates smoothly, and at the same time the rack member
-C third via the pinion gear 14 by the gear part i5a
Move in the direction shown by the arrow (A) in the diagram. The edge of the disk A further fits into the long groove 8a of the holding member 8, and its insertion posture is controlled. A state in which the disk A is completely inserted into the storage chamber 3 in this manner is shown in FIGS. 3 and 5.

In this state, a force is applied to 8-15 to push out the disc A. The holding part is held by the protrusion 8-15 which is in contact with the protrusion 9b of the operating member 9 due to the traction force of the tension coil spring 10. 18b in the counterclockwise direction, and lightly presses the disk ■ in the insertion direction through the pin 20, so even if the magazine is tilted and the slit 4a side is facing downward, the disk ■ will not be inserted. It can be pulled out naturally from the storage room 3 and will not fall.

In this way, the disks 3.3.
3..., then hold the magazine in your hand and insert it into the magazine storage section of a CD player (not shown).When you specify the order in which you want to play the discs ■, the magazine will be automatically loaded. The disc itself moves up and down and stops at the position where it sends out the disc ■ onto the turntable. Therefore, as shown by imaginary lines in FIGS. 5 and 7, the operating member B is operated by a mechanism not shown, and the operating portion 8a of the operating member 9 is pushed in the direction of the arrow (B). and,
The operating member 9 moves in the direction of the arrow (b) as shown in FIG. 7 against the pulling force of the tension coil splinter 10. At the same time, the cam pin 11 also moves, and as shown in imaginary lines in FIGS. 5 and 6 and as shown in solid lines in FIG. , when the pressing force by the operating member B is released, the operating member 9
is the tension coil spring 1 while the engaging protrusion 13b of the rack member 13 is retained by the engaging portion 11a of the cam pin 11.
It slides back to its original position with a traction force of 0. At this time, the rack member It will be pushed out to the outside.

At this time, the holding lever 18 does not pose any obstacle to the passage of the magazine (2) because the protruding portion i8b and the protruding piece 9b are separated from each other. Further, when the locking part 11a of the cam pin 11 returns to its original position together with the operating member 9, it is released from the locking projection +3b of the rack member 13 by the cup part 12, so that the rack member 13 is then As shown in Figure 3, a free state FE is obtained. The pushed out magazine (2) is transferred onto the turntable by a disc transfer member (not shown).

The above explanation is about the case where the magazine is attached to a CD player with an autochanger. However, when replacing the disks (or holes) attached to the magazine storage chambers 3, 3, 3... Take it out from the magazine storage chamber, press the operating portion 9a of the operating member 9 with your finger instead of the operating member in the direction shown by the arrow (B) in FIG. 5, and align your hands in the same manner as described above. A movement is made, and the magazine ■ stored in each storage chamber 3.3.3, the jar, and the magazine ■ stored inside is pushed out.
If you keep the a side facing upward, the pushed out disc
■ is held by the pin 19 of the holding lever 18, and
As shown in the figure, it stops with about two-thirds of it out of the storage chamber 3, so you can take it out by lightly pinching the edges with your hands and put it back into the case (not shown). be.

In the above description, the case where the magazine accommodates a plurality of disks has been described, but it goes without saying that the magazine may accommodate a negative number of disks.

(Effects) As explained in detail above, according to the present invention, only the disk is stored, so 1. In addition to being able to make the magazine thinner, it is also possible to achieve effects such as being able to reliably insert and remove disks with a light touch and operation.
