DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-disc player having a disc magazine capable of storing a plurality of discs.

[0002]

2. Description of the Related Art In recent years, various multi-disc players have been developed in which about 6 to 10 discs are stored in one place so that each disc can be arbitrarily played at any time.

[0003] This kind of multi-disc player basically disposes a disc horizontally from a magazine in which a plurality of discs are vertically stacked and stored, as disclosed in, for example, JP-A-63-212159. Transport in the direction
After the transported disk is held by the holding means, the disk is transported onto the turntable.

By the way, there are various sizes of disks (for example, 8 cm and 12 cm), and in the case of the above-mentioned configuration, each disk is placed in a predetermined positional relationship with respect to the turntable. It must be held by holding means.

As a method for achieving such an object, for example, the size of the disk is determined while the disk is being transported,
Thus, the end position regulating plate for regulating the final movement position of the disk is moved by a motor or the like to determine the amount of movement of the disk.

[0006]

The holding means moves along the direction in which the disks are arranged, and is lightweight (reducing the load on the drive source of the holding means) and compact (moving means). However, the addition of the above-described structure for restricting the amount of movement leads to an increase in the size and size of the holding means. Further, a means for controlling the motor in accordance with the means for detecting the size of the disk and a means for transmitting the output of the motor to the end point position regulating plate are required, so that the configuration is complicated.

[0007]

A multi-disc player according to the present invention holds a disc magazine capable of accommodating a plurality of large-diameter and small-diameter discs, a disc playing means, and a disc horizontally conveyed from the disc magazine. A holding means, a large diameter stopper provided on the holding means, for stopping the movement of the large diameter disk, and a stop for the small diameter disk, the movement of which is stopped, and the rotation of the large diameter disk. A small-diameter stopper, wherein the small-diameter stopper is configured to hold the disc at a predetermined position with respect to the disc playing means.
The rotary shaft is vertically rotatable so that the force received by the movement of the small-diameter disk coincides with the direction of the rotating shaft.

[0008]

The present invention is configured as described above,
The movement of the large-diameter disc is stopped by the large-diameter stopper, and the movement of the small-diameter disc is stopped by the small-diameter stopper.

The stopper rods (28) (28) of 6) abut the upper surface of the 12 cm disc, and the center of the 12 cm disc is located at a position coincident with the center of the turntable (4). or,
The 12 cm disk is held between the upper rollers (13) and (14) and the lower rollers (17) and (18) and is held by the elevation mechanism (6).

When the state shown in FIGS. 4 and 5 is detected by a detecting means (not shown), the gear rods (32) and (32) are rotated to move the elevation mechanism (6) downward. As the downward movement of the elevation mechanism (6) proceeds, the gear portions (29) (29) of the 8 cm stoppers (26) (26) mesh with the gear plates (34) (34). When the elevation mechanism (6) moves further downward in this state, the 8 cm stoppers (26) (26) are moved to the gear portions (29) (29).
The gear rotates in the counterclockwise direction in FIG. 2 by the engagement of the gear plates (34) and (34), and when the 12 cm disk is clamped, as shown in FIG.
8) (28) is separated from the 12 cm disk.

By the way, since the elevation mechanism (6) is set so as to move slightly downward as described above even if the 12 cm disk is placed on the turntable (4), the 12 cm disk is mounted on the turntable (4). 7), the inside of the elevation mechanism (6) moves relatively upward, and the state shifts from FIG. 7 to FIG.
Therefore, at the time of clamping, the contact between the 12 cm disc and the 12 cm stopper (25) is released.

Next, an 8 cm disk (D8) in the state of FIG.
Is removed, the 8 cm discs are rolled into their respective rollers (13) (14) as in the case of the 12 cm discs.

When the elevation mechanism (6) moves further downward in this state, the stoppers (26) (26) for 8 cm are engaged with the gear portions (29) (29) and the gear plates (34) (34), so that the stoppers shown in FIG. When the disc is rotated counterclockwise and the 8 cm disc is clamped, the stopper rod (28) (2
The contact between 8) and the 8 cm disk is released.

[0016]

As described above, according to the present invention, the small-diameter stopper is disposed so as to be vertically rotatable so that the force received by the movement of the small-diameter disc coincides with the direction of the rotating shaft. As described above, there is no need to provide a motor or the like for controlling the amount of movement of the disk in the holding means, and the holding means can be reduced in size and weight. Further, since it is not necessary to control each stopper according to the detection of the size of the disk, the configuration is simplified.
