Problems solved by technology

Therefore, although it is conceivable to make the disc cartridge 10 smaller by reducing the width Wb of the opening 12a, the width of the opening 12a cannot be reduced because the opening 12a must allow the turntable 110 and the pick-up device 130 to approach the disc D.

Embodiment Construction

[0015] Figure 4 A disc cartridge according to a first embodiment of the present invention is shown.

[0016] refer to Figure 4 , the disc case 20 includes: a housing having an upper portion 21 and a lower portion 22 forming an inner space for mounting the disc D; and a shutter 23 for selectively An opening 22b formed through the lower portion 22 of the housing is opened and closed.

[0017] Wherein, the shutter 23 is made of flexible plastic resin, and is installed through the slots 21a and 22a, which are formed through the upper part 21 and the lower part 22 of the housing, so that the shutter 23, in a -shape A strip form extends from the upper surface to the lower surface of the housing. That is, one end of the shutter 23 is slidably supported by a guide plate 25a on the upper portion 21 of the housing, the other end is bent around the lower portion 22 of the housing through the slots 21a and 22a, and The guide plate 25b on the lower portion 22 is slidably supported. ...

Abstract

A disk cartridge includes a case which contains a disk, and a shutter which opens / closes at least one opening formed in the case. The shutter is configured to be foldable around upper and lower surfaces of the case, and slides on the upper and lower surfaces of the case to open / close the opening. Since the shutter opens / closes the opening while being folded around the upper and lower surfaces of the case, a movable distance of the shutter for opening / closing the opening can be fully accommodated even though the size of the disk cartridge is reduced. In addition, applying the configuration of the shutter to a double-sided disk cartridge prevents an inflow of dust from entering into the double-sided disk cartridge since the shutter closes an opening, which is not in use, during a recording / reproducing operation.

Description

technical field [0001] The present invention relates to a disc case for mounting a disc of an information recording / reproducing medium, and more particularly, the present invention relates to a disc case in which a structure for opening / closing an opening for a pickup device to approach a disc is improved , which will help reduce the size of the disc cartridge. Background technique [0002] Usually, such as figure 1 and 2 Said, the disc case 10 is to be mounted on the disc D used in the recording / reproducing apparatus 100, and the disc case 10 includes: a housing having an upper portion 11 and a lower portion 12, the upper portion 11 and the lower portion 12 An inner space for accommodating the disc D is formed; and a shutter 13 for selectively opening and closing the opening 12a formed through the lower portion 12 of the casing, so that the pickup device 130 of the recording / reproducing apparatus 100 can Approach disc D. Reference numeral 150 denot...
