Abstract

PURPOSE:To use both disks having different large and small diameters by moving a small diameter disk housing part forming member in a disk housing part and forming a smaller diameter disk housing part in the disk housing part. CONSTITUTION:Three pieces of the small diameter disk housing part forming member 3 are arranged movably toward the inside of the disk housing part 2 for housing a 12cm CD on the outer side of the housing part 2 in a disk tray 1. The housing part is provided with a notched part 6, while three pieces of a disk housing part forming member fitting part 7 are formed by notching an outer circumferential wall 5 at each 120 degrees. Then, when the member 3 is rotated by approximately 180 degrees to become so-called the inverted state, the member 3 intrudes into the housing part 2 to form the smaller diameter disk housing part 4 for housing an 8cm CD in the center of these members 3 by their top-most vertices of semicircular arcuate parts 13. By this method, the different large and small diameter disks are used, and the carriage of these disks can securely be performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc tray for conveying discs in a disc changer such as a CD changer, and more particularly to discs of different sizes.

[0002]

2. Description of the Related Art In a CD changer, when a CD having a diameter of 8 cm, which is smaller than a standard size of 12 cm, is conveyed by a tray, the following method has been conventionally used.

(1) A commercially available small-diameter disk attachment is used.

(2) A tray dedicated to a small-diameter disk is used.

[0005]

However, the above-mentioned conventional method has the following problems.

(1) The former method of using a commercially available attachment for a small-diameter disk involves the trouble of purchasing the attachment and assembling it on the tray, and the reliability of the performance is poor.

(2) The latter method of using a tray dedicated to a small-diameter disc has the trouble that a dedicated tray must be prepared, and the disc tray must be replaced with a CD changer, which is troublesome to use. It costs.

There are problems such as the above.

Some of the so-called roulette type CD changers can be used as they are even for small-diameter discs, but in this case, operations other than during horizontal use are guaranteed.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a disc tray which can be used for a small-diameter disc without using a special attachment in a CD changer other than the roulette type. It was done.

[0011]

In the disc tray of the present invention, a plurality of small diameter disc accommodating portion forming members are arranged outside the disc accommodating portion so as to be movable toward the inside of the disc accommodating portion. By moving the forming member into the disc accommodating portion, a disc accommodating portion having a smaller diameter than that can be formed in the disc accommodating portion.

Further, in the present invention, in particular, the small diameter disc accommodating portion forming member is rotatably attached to the upper surface of the tray, and the small diameter disc accommodating portion forming member is placed outside the disc accommodating portion. By reversing and placing it in the disc containing portion, a small-diameter disc containing portion is formed in the disc containing portion.

[0013]

By moving the small-diameter disc containing portion forming member arranged outside the disc containing portion into the disc containing portion, a small-diameter disc containing portion is formed in the disc containing portion, and a large disk tray is formed. It is possible to have compatibility so that both the large diameter disc and the small diameter disc can be used.

Further, it is possible to switch between the disk accommodating portion for the large diameter disk and the small diameter disk accommodating portion for the small diameter disk by a simple operation of reversing the small diameter disk accommodating portion forming member. .
