DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc changer for selecting a disc such as a CD or an LD stored in a disc storage body and reproducing the disc.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, as a disc changer, a disc housing 2 for accommodating a plurality of discs 1 (only one disc is shown in the figure) is provided. A plurality of disks 1 housed in the body 2 are moved in the thickness direction to take in a desired disk 1 from the disk housing 2 and reproduce sound therefrom. After the reproduction, the original of the disk housing 2 is restored. A device equipped with a transporter 3 for returning to a position is known. In the above figure, the disk 1 is moved from the disk housing 2 as described above.
The means for loading the disc 1 into the carrier 3 and the means for returning the reproduced disc 1 from the carrier 3 to the disc housing 2 as described above are not shown.

In the above-described disc changer,
As described above, when the disk 1 is loaded from the disk storage unit 2 into the transport unit 3, the position of the desired disk 1 stored in the disk storage unit 2 and the transfer unit 3 and the transfer unit 3
When the disk 1 is returned to the disk housing 2 from the above, it is necessary to accurately position the position where the disk 1 is stored in the disk housing 2 and the position of the transporter 3. For this positioning, the recesses 2a are provided in the disc housing 2 at equal intervals of a pitch P coaxially with the center axis in the thickness direction of each of the stored discs 1 (hereinafter referred to as coaxial with the discs).
The positioning member 6 is slidably provided on the carrier 3 and the positioning member 6 and the concave portion 2a are fitted to each other so that the desired disk 1
And the mutual positional relationship between the position and the carrier 3 are determined. The width b of the positioning member 6 is equal to or slightly smaller than the width B of the recess 2a. Also,
The drive system of the positioning member 6 is not shown.

[0004] A disc guide 5 is rotatably mounted on the transfer machine 3, and has a groove 5a coaxial with the disc having a cross-sectional shape sandwiching the thickness direction of the disc at both ends. Fig. 7 when reproducing 1
, The groove 5a is slightly rotated to a position where the groove 5a does not contact the outer peripheral edge of the disk 1. At the time of loading the disc 1 from the disc housing 2 into the transporter 3 or the like, FIG.
As described above, the spring 1 and the stopper 9 keep the disk 1 in parallel so as to be in contact with the outer peripheral edge of the loaded disk 1.

[0005]

By the way, in order to take out the disc 1 housed in the disc housing 2 for exchanging it with a new one, that is, to eject it, the desired disc 1 is sandwiched between fingertips or the like. I was pulling out. But,
When the storage efficiency of the disks is increased, the distance between the disks becomes narrower, so that a fingertip or the like does not enter the space between the disks. For this reason, the tip of tweezers or the like has been pinched and grasped by an extremely thin object, or several discs have been collectively taken out and an unintended disc has been returned. Furthermore, if the distance between the disks is small, the location of the desired disk is not clear, and another disk may be taken out by mistake. The present invention
In view of the above, it is an object of the present invention to provide a disk changer that can easily take out a desired disk from a disk storage body with a simple configuration.

[0006]

In order to solve the above-mentioned problems and to achieve the above object, a disk-shaped recording medium loading mechanism according to the present invention comprises a disk guide rotatably mounted on the carrier. The rotating disk guide is selectively rotated, and the disk 1 moving as described above can be guided in the first rotating position as described above, and the second rotating In the position, the loaded disk is released to enable disk reproduction, and in the third rotation position, a desired disk 1 is pushed out of the disk housing 2 and projected out of the disk housing 2. It is assumed that. Then, a slider having a positioning projection that can be fitted into the concave portion of the disk storage body is slidably provided on the carrier, and the positioning projection is fitted into the concave portion, so that the disk storage body and the transporter And the rotating disk guide may be rotated in conjunction with sliding of the slider. Further, a spring-shaped portion is integrally formed with the rotating disk guide, and the rotating disk guide is rotated to the first rotation position by a spring force of the spring-shaped portion, and is opposed to the spring-shaped portion. By rotating the rotating disk guide, the rotating disk guide may be rotated to the second rotation position.

[0007]

In the disk changer constructed as described above, the disk can be made to protrude sufficiently from the disk housing, so that the disk can be easily removed manually. Further, unlike the related art, the disc to be taken out can be selected by using a well-known search function of the disc changer instead of being visually selected, so that a wrong disc is not taken out. The take-out (discharge) mechanism can be easily provided by only slightly changing the configuration of the lower side of the transporter without changing the configuration of the conventional disk storage body described with reference to FIG. 5 and the like.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In these figures, the same reference numerals as those in FIGS. 5 to 7 used for describing the conventional example denote the same elements unless otherwise specified. Reference numeral 12 denotes a rotating disk guide, which is attached to the transporter 3 so as to be rotatable around 3a. Reference numeral 12a denotes a gear portion of the disc guide 12, which meshes with the joint gear 13. Reference numeral 12b denotes a spring-like portion of the disc guide 12, which contacts the projection 3b of the transporter 3 and holds the disc guide 12 at a position to guide the disc 1 when taking in and returning the disc 1.

Reference numeral 12c denotes a groove of the disc guide 12, which is coaxial with the disc 1 as described above.
The disk 1 is guided when the disk 1 is loaded and returned. Reference numeral 14 denotes a slider, which has a positioning projection 15 at its tip and has a configuration substantially similar to that of the positioning member 6, but the projection 15 is long because of a large sliding amount. Further, a rack section 16 having an intermittent mechanism is also provided. The disc is attached to the carrier 3 by a guide pin 3c so as to be movable in the direction of taking out and returning the disc. A lever 17 is connected to the other end of the slider 14. The lever 17 is fitted with a cam 18, and the position of the slider 14 is controlled by the movement of the cam 18. Since the rack portion 16 of the slider 14 meshes with the gear portion 12a of the rotating disk guide 12 via the joint gear 13, the movement of the cam 18 controls the movement of the rotating disk guide 12 via the slider 14. . In addition, the positioning member 6
The disk guide 5 is the same as the conventional one.

FIG. 2 shows a state in which a disk search is performed, in which the slider 14 is shifted to the right in the figure, and the positioning projection 15 is located at a position separated from the disk housing 2. Further, the transporter 3 is in a state of being movable in the disk thickness direction. At the time of loading and reproducing the disc 1, after the transporter 3 is moved to a desired position of the disc 1 in a known manner, the positioning member 6 is fitted into the recess 2a, and the slider 14 is slightly moved to the left by the cam 18. As a result, the positioning projections 15 are fitted into the recesses 2a, and the positioning between the disk housing 2 and the transporter 3 is completed.
Although the driving means of the cam 18 is omitted, a known means can be used. In this state, the intermittent mechanism of the rack 16 operates, and the rack 1
Since the gear 6 and the joint gear 13 have not yet engaged with each other, the rotating disk guide 12 is maintained at a position where the disk outer shape can be held.

After that, when the disk 1 is loaded from the disk housing 2 into the transporter 3 by well-known means (not shown), the disk 1 is brought into the reproducing state shown in FIG. Is separated from the outer shape of the disk, and the disk reproduction is started. At this time, the spring-like portion 12b of the rotating disk guide 12 bends, and when the reproducing state is released, it returns to the position for guiding the disk outer shape again. Returning the disk 1 to the disk housing 2 is reversed.

Next, the operation when the disc is ejected will be described.
As shown in FIG. 2, the disk 1 is
4, the positioning member 6 is fitted into the recess 2a and the slider 14 is
The positioning projections 15 are fitted into the recesses 2a to perform positioning between the disk housing 2 and the transporter 3. Then, the slider 14 is further moved leftward in the figure by the cam 18. As a result, the rack 16 and the joint gear 13 begin to mesh with each other, and the rotating disc guide 1
2 starts to rotate left. When the slider 14 further moves to the left, the tip of the rotating disc guide 12
And starts pushing the disk 1 out of the disk housing 2 against the holding force of the disk holding spring 10, and the disk 1 projects about halfway from the disk housing 2 and is ejected here. The operation is completed. still,
The width of the rotating disk guide 12 must be smaller than the distance between the adjacent disk surfaces.

As described above, when the disk 1 is sufficiently protruded from the disk housing 2, it becomes extremely easy to remove the disk 1 by hand. Also, as before,
The disc to be taken out is not selected visually, but is selected using a well-known search function of the disc changer, so that the wrong disc is not taken out. In addition, the discharge mechanism can be easily provided only by slightly changing the configuration of the lower side of the transporter 3 without changing the configuration of the conventional disk storage body 2 described in FIG. In the above embodiment, the rotating disk guide 12 operates in conjunction with the slider 14, but the rotating disk guide 12 may operate alone. However, in this case, the drive system of the rotating disk guide 12 becomes complicated. In the above embodiment, the rotating disk guide 12 is arranged on the lower side, but the same effect can be obtained by disposing it on the upper side.

[0014]

The present invention is as described above. With a simple structure, the disk 1 can be sufficiently protruded from the disk housing 2, and the disk 1 can be easily taken out by hand. In addition, since a disc to be taken out is selected using a well-known search function of the disc changer, it is possible to prevent a wrong disc from being taken out.
