Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc magazine suitable for use in a multi-disc player, in which a plurality of discs can be arbitrarily selected and sequentially played automatically.

(Background Art) Recently, it is called a CD or a compact disc.
An analog type that reproduces the record engraved on a disc with an outer diameter of about 120 mm using a laser beam and reproduces the record engraved on the conventional record board using a record needle Is dominated the record player market.

The diameter of the above-mentioned disc is smaller than that of the conventional record, but if the song is about 3 minutes, about 20 can be recorded.
With ~ 6 discs, you can record about 100-120 songs, so you can cover the main songs of various genres, so you can store these 5-6 discs in one place. Various multi-disc players have been developed, especially for general household use, which are constructed so that discs can be automatically played in sequence.

By the way, there are two types of disc magazines used in this type of multi-disc player: one that puts the disc on a tray and the other that stores the disc as it is. Belong to

Whichever method is used, when the disc is taken out from the magazine, it is necessary to provide a difference in the push-out width of the disc depending on whether the disc is played or the disc is exchanged. , Has a first slide lever that is mechanically operated when playing, and a second slide lever that is manually operated when exchanging the disc. When the first slide lever is operated, the disc is pushed out greatly, The disc is pushed out a little when the slide lever is operated, and after that, it can be held and taken out by hand. This is to prevent the playing surface from being accidentally dropped and damaging the playing surface when the disk is manually replaced.

However, even if that is the case, the strength of how the force is applied when the second slide lever is manually operated varies depending on the operator. Therefore, if the disk is pushed out strongly when operated strongly, This tends to occur, and this is presented as an important problem to be solved especially in the system of directly storing the disc in the magazine without placing it on the tray.

(Technical problem) In view of the above-mentioned point, the object of the present invention is to prevent the disc from jumping out of the magazine when the second slide lever is manually operated, even if there is a slight difference in how to apply the force. There is a disc magazine that can be surely prevented.

(Technical Means) In order to achieve the above-mentioned technical problem, the present invention is directed to an eject lever by a first slide lever for mechanical operation and a second slide lever for manual operation of a disc housed in a case body. In which the disk is moved to push it out of the case body, a braking means is provided at the disk outlet of the case body, and the braking means strongly acts on the disk when the second slide lever is operated. It was done.

(Operation) With the configuration described above, when the second slide lever is manually operated, the braking means strongly acts to hold down the disc, so that even if the second slide lever is operated with a strong force, the disc will not move. It is possible to reliably prevent jumping out of the magazine.

As shown in FIG. 7, the second slide lever 16B is the same as the second slide lever 16A except that the position of the pressing protrusion 16c is different from that of the second slide lever 16A. This is to prevent the pressing projections of the slide levers that are adjacent to each other at a narrower interval from being adjacent to each other in the vertical direction and obstructing them when operating with a finger as described later. These second slide levers 16A and 16B are
The slide levers 15 are alternately paired.

The engaging groove 15c of the first slide lever 15 is shown in FIGS.
As shown in FIG. 3, the engaging pin 17a provided at the end of the eject lever 17 beyond the fulcrum is engaged.

Similarly, as shown in FIGS. 8 to 13, the first lock lever 18 has six engaging protrusions 18b, 18b ... Which are arranged at equal intervals with the engaging protrusion 18a, and the engaging protrusion 18b. , 18b ... Are accommodated between the engaging protrusions 16d and 16e of the second slide levers 16A and 17B.

Then, on one side of the case body 8, as shown in FIGS. 8 to 13, the second lock lever 20 is urged in the clockwise direction by the compression coil springs 23, and the screw 2
A key-shaped control projection 20a, which is attached rotatably by means of 5 and is provided at one end beyond the fulcrum, is fitted into a notch 8b provided on one side of the case body 8 and It projects to one side. The engagement protrusion 20b provided on the other end of the second lock lever 20 is engaged with the engagement protrusion 18a of the first lock lever 18.

In this way, the braking means is the engaging projection 16d in this embodiment,
The second slide levers 15A and 15B having 16e and slidably accommodated in the lever accommodating box 7, and the engagement protrusions 16d and 16e of the second slide levers 15A and 15B.
18b, a first lock plate 18 pivotally supported by the support shaft 22 in the lever storage box, and an engagement projection 20a that engages with the engagement projection 18a of the first lock plate 18, While projecting the projecting piece 20a on the moving track of the disk,
The second lock plate 20 is attached to one side of the case body 8 by being urged to rotate in one direction.

Next, the operation and effect will be described. First, in the state before the disc is stored in the magazine 2, the pressing portion 17b of the eject lever 17 in the magazine 2 is
Normally, as shown in FIG. 9, it is located at a position rotated from the center of the disk storage chamber 11 toward the case body 8. At this position, the engagement pin 17a is pushed by the push pin 19 and turned counterclockwise. The stable position is maintained by being urged. First slide lever 15 and second slide lever 16
A and 16B are in positions moved toward the rear plate 5. More specifically, the first slide lever 15 is the eject lever 17
When the is in the rotation position as shown in FIG. 9, it is in the position moved to the rear plate 5 side as much as possible, as shown in FIG.
When the eject lever 17 is in the rotation position shown in FIG. 11, it is in a position slightly moved to the case body 8 side, as shown in FIG. The first lock lever 18 and the second lock lever 20 are the second slide lever 16A.
And 16B are slidable in the direction of the case body 8 in any of the above cases, they are in the positions shown in FIGS. 11 and 12 by the action of the compression coil springs 23.

Therefore, when the disc D is first held by hand and is inserted from the uppermost slit 8a provided at the tip of the magazine 2, for example, the disc D has a convex lens shape in which the slit 8a becomes wider toward the center thereof. Since the upper rib 9 and the central partition plate 10 are provided with taper ribs 8a, 9a and 10a which become higher toward the rear plate 5, the performance surface does not hit these members, While pushing the pressing portion 17b of the eject lever 17 at its edge, it is inserted into the disc housing chamber 11 and is carried by the groove portions 12a, 13a of the disc carrying portions 12, 13, as shown by the phantom line in FIG. In addition, the leaf spring 24 holds it so that it does not come out easily.

At this time, since the first lock lever 18 is rotatable in the clockwise direction, the second lock lever 20 pushes the control projection 20a by the edge of the disk D inserted from the slit 8a.
The disk D is allowed to pass by rotating counterclockwise against the biasing force of the compression coil springs 23.

On the other hand, as shown in FIG. 8, the pushed eject lever 17 rotates clockwise around the support shaft 21 as a fulcrum to retract to the rear plate 5, and pushes the engagement pin 17a to push the push pin 19a.
By the action of, the disk D is in a stable state without being pushed. At the same time, the first slide lever 15 is moved through the engagement pin 17a.
Slides together with the second slide lever 16A in the direction of inserting the disc D, that is, toward the case body 8 side, and the first lock lever 18
And the second lock lever 20 returns to the original position as shown in the figure by the action of the compression coil springs 23, 23.

In this way, the disks are sequentially inserted from the respective slits 8a into the respective disk storage chambers 11, 11, ...
One disk can be stored in this magazine 2.

Therefore, as shown in FIG. 1, the magazine 2 in which the discs are stored is stored in the magazine storage portion 3 of the multi-disc player 1, and when a performance command is issued, as shown in FIG. The engaging lever 26 of the disk take-out means (not shown) has moved to the engaging protrusion of the first slide lever 15.
It engages with 15b and pushes it toward the rear plate 5 side. Then, the eject lever 17 engaging the engaging pin 17a with the engaging groove 15c of the first slide lever 15 rotates counterclockwise around the support shaft 21 as a fulcrum, and its pressing portion 17b causes the edge of the disk to rotate. The part is pushed to push it forward from the disk storage chamber 11 through the slit 8a. At this time, the second lock plate 20 rotates counterclockwise against the biasing force of the compression coil springs 23, 23 to retract the control projection 20a from the passage path of the disk, and the disk is pushed by a certain portion. This causes it to rotate clockwise and push out the disc. This is pin 1 in the long holes 15a and 15b of the first slide lever 15.
Since the second slide lever 16A in which 6a and 16b are fitted is slidable in the direction of the case body 8, the first lock lever 18
This is because the rotation in the clockwise direction becomes free.

In this way, when the disc storage chamber 11 of the magazine 2 which has pushed out the discs for playing receives the finished discs for storing, the return means for the discs (not shown) finishes the playing. Since the disc is inserted through the slit 8a just like you insert it by hand,
The disc is stored as described above.

As described above, the disks stored in the magazine 2 are sequentially taken out and stored automatically by manual operation.

Next, when manually ejecting the disc stored in the magazine for replacement, as shown in FIG. 10, the pressing protrusion 16c of the second slide lever 16A (or 16B is the same) is used. When pushed to the rear plate 5 side with fingers, the first slide lever 15 also slides downward, but the second slide lever 16
The engagement protrusion 16e of A is the engagement protrusion 18b of the first lock lever 18.
The first slide lever 15 is engaged with and stopped.
Does not move to the rear plate 5 side to the maximum as in the manual operation described above.

Therefore, as shown in FIG. 11, the eject lever 17 rotates only up to the substantially central position of the disc storage chamber 11. At the same time, the second lock lever 20 is locked via the first lock lever 18 and is prevented from rotating in the counterclockwise direction, so that the control projection 18a is pushed out from the passage path of the disc without being retreated. Push the part horizontally to brake so that it does not jump out. Here, the disc is stopped in a state of being pushed out from the magazine 2 by about half, and after that, the disc can be taken out by hand. At this time, the disc is the second lock lever.
The control protrusion 20a is provided at the edge of the edge using the inherent elasticity of the 20.
Is pushed counterclockwise and pulled out.

When the disc is replaced by the manual operation as described above, the rotation range of the eject lever 17 is limited and the rotation of the second lock plate is also limited as described above. It is possible to reliably prevent the disc from popping out from the inside of the magazine even if the force applied by the fingers is weak or strong.

(Effect) As described in detail above, according to the present invention, the disk can be immediately stored without damaging the playing surface of the disk, and the stored state can be stably maintained, and the manual operation can be performed. When replacing a disc, the disc will not jump out of the magazine even if there is strength or weakness in the force applied, so it is possible to reliably prevent it from dropping and damaging the playing surface. Is.
