Abstract

(57) [Summary] [Structure] A disc magazine 1 in which disc trays 3 are arranged in a page shape of a book, and disc storage recesses 3b are formed in these disc trays 3 respectively. [Effect] Since the book-shaped disc magazine 1 is opened halfway and the disc 24 is taken out and played back as it is, approximately 1/3 of the outer diameter of the disc 24 being played should be inserted into the disc magazine 1. The size of the disc reproducing device 103 in the disc pull-out direction can be shortened by at least about 1/3 of the outer diameter of the disc 24. Therefore, the disc reproducing device 103 can be made compact.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc magazine for mounting a plurality of discs on a disc reproducing device.

[0002]

[Prior Art]

 FIG. 5 is an external view of the vehicle-mounted disc player (the diagram is to be seen in the direction of the reference numeral). Discs such as compact discs (CDs) are placed on the disc tray 101, and the disc trays 101 ... Are disc magazines 102. The disc magazine 102 is inserted into the insertion port 104 of the disc reproducing device 103 as indicated by an arrow.

In the disc reproducing device 103, only one disc tray 101 is pulled out to the play position and reproduced by an optical pickup or the like.

FIGS. 6A to 6C are operation diagrams of a conventional disc magazine, and FIG. 6A shows that the disc tray 101 is completely pulled out from the disc magazine 102 and faces the play position. Show.

FIG. 6B shows another type of disc magazine, in which the disc tray 105 is fixed to the disc magazine 106 by a pin 107, and pivoted as shown by the arrow to be pulled out to the play position. Be done.

Further, FIG. 6C shows a system in which a disc tray is not used, and a bare disc 108 is pulled out from a disc magazine 109. The disc magazine 109 has an extremely complicated internal structure, and a felt (not shown) or the like is attached so as not to scratch the disc 108.

[0007]

[Problems to be solved by the device]

 Therefore, although the disc tray method is the mainstream, it is necessary to completely pull out the disc trays 101 and 105 from the disc magazines 102 and 106 in both FIGS. 6 (a) and 6 (b). Even if the dimension in the disc pull-out direction is small, it is the sum of the disc magazines 102 and 106 and the disc trays 101 and 105, and it is difficult to achieve compactness.

Further, although it is necessary to manually put the discs on the disc trays 101 and 105, it is not easy to take the disc trays 101 and 105 in and out of the disc magazines 102 and 106 and further take the discs in and out of the disc magazines 102 and 106. Is difficult.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is characterized in that disc trays are arranged in a page shape of a book, and disc storage recesses are formed in these disc trays.

[0010]

[Action]

 The book-shaped disc magazine is opened halfway, and the disc is taken out and played as it is.

[0011]

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings should be viewed in the direction of the reference numerals.

FIG. 1 is a cross-sectional view of a disc magazine according to the present invention. The disc magazine 1 is a magazine body 2 having an L-shaped cross section corresponding to a spine and a back cover of a book, and a disc tray 3 corresponding to a page of a book. And a lid 4 which covers the front cover and a lid locking mechanism 6 which will be described later.

FIG. 2 is an exploded perspective view of the disc magazine of the present invention. The magazine body 2 has a disc storage recess 2a formed therein, and a vertical groove 2b for locking one end of each tray on the spine cover side. 2b is formed, and lid stop claws 2c, 2c are provided in a protruding manner.

The disc tray 3 is provided with a disc housing recess 3b in a flat plate portion 3a, and a round bar 3c is attached to one end thereof.

Similarly, the lid 4 is a flat plate, is provided with round bars 4a, 4a corresponding to the lid stopper claws 2c, 2c, and lock hooks 4b, 4b are hung on the lower surface.

FIG. 3 is a view showing a lid lock mechanism of the disc magazine of the present invention. The lock lever 8 of the lid lock mechanism 6 locked to the magazine body 2 by the pin 7 is pulled in the lock direction by the spring 9 to Since it is locked to the lock hook 4b, the lid 4 does not open upward. Reference numeral 10 is a limiting pin that prevents the rocking lever 8 from excessively swinging.

When the lower portion of the lock lever 8 is pushed, the lock lever 8 swings in the opening direction, and the lid 4 can be opened.

The operation of the disc magazine having the above structure will be described below.

4 (a) to 4 (c) are diagrams for explaining the operation of the disc magazine of the present invention, and FIG. 4 (a) shows the disc magazine 1 facing the turntable 20 and the optical pickup unit 21 in the reproducing apparatus. It is characterized in that it is mounted, and the tip of the disc magazine 1 is located very close to the turntable 20.

FIG. 4B shows a page opening mechanism (not shown) that opens a predetermined page, that is, the disc tray 3 in a half-open state, inserts the arm 22 therein, and grips the disc 24 with the suction pad 23 at its tip. To do. The arm 22 waits above the disk 24 after placing the disk 24 on the turntable 20.

FIG. 4C shows a reproduction state, in which the disc 24 of the turntable 20 is reproduced in a state in which about 1/3 of the diameter is inserted into the disc magazine 1.

In the figure, 25 is a vacuum tube and 26 and 27 are pinion racks for moving the turntable 20 and the optical pickup unit 21 to a predetermined level.

[0023]

[Effect of the device]

 As described above, according to the present invention, the book-shaped disc magazine is opened halfway, and the disc is taken out and reproduced as it is. Therefore, about 1/3 of the outer diameter of the disc being reproduced is the disc magazine. The size of the disc reproducing device in the disc pull-out direction can be shortened by at least about 1/3 of the outer diameter of the disc.

Further, before being mounted on the disc reproducing apparatus, the disc can be put in and taken out from the disc magazine by turning the pages of the book, which makes the handling extremely easy.
