Abstract

PURPOSE:To easily assemble a case and to miniaturize the case by approximately opening one face and opening and closing an aperture part for recording/ reproducing on the recording face side with a shutter freely slidably attached to a part formed at a height lower than the surface of a main body. CONSTITUTION:The recording/reproducing face side of an optical disk D stored in a recessed part 12 provided with a step part 14 and an aperture part 13 for recording/reproducing in the center is covered with a storage case whose one face is approximately opened. A case main body 11 is provided with a part lower than the surface of the main body 11 as a slide member 16, and the aperture part 13 is freely opened and closed by the member 16 and a sliding shutter 15. By this constitution, a recording medium storage case is obtained which is easy to assemble and is thinner to have the thickness approximated to the thickness of a disk D furthermore and is miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information recording medium storage case that is attached to an information recording/reproducing apparatus with an information recording medium stored therein.

[Prior Art] In recent years, optical discs that perform recording and reproduction using light sources such as lasers have been frequently used as information recording media.
A storage case is being considered that is attached to a recording/reproducing device with these information recording media stored therein.

FIG. 4 is a perspective view of this conventional storage case. A substantially rectangular storage case 1 is configured to enclose a disk-shaped information recording medium, and is used for recording and reproducing information on the information recording medium. A shutter 3 is attached to the storage case 1 in order to close the opening 2 opened for the
It is slidably attached to the

[Problems to be Solved by the Invention] However, in the conventional example described above, the storage case 1 covers both sides of the information recording medium, and the total thickness of the storage case 1 is smaller than the thickness of the information recording medium. It has more than doubled. Therefore, the information recording/reproducing device also needs to be thicker accordingly, and furthermore, the number of component parts of the storage case 1 increases, resulting in an increase in parts cost.

[Object of the Invention] An object of the present invention is to solve the above-mentioned drawbacks of the conventional example, and to provide an information recording device that is easy to assemble by leaving almost one side of the storage case open and covering only the recording surface side of the information recording medium. The purpose is to provide a media storage case.

[Summary of the Invention] The gist of the present invention for achieving the above-mentioned object is to provide an information recording medium storage case that is attached to an information recording/reproducing apparatus with the information recording medium stored therein, and in which the information recording medium is stored in the information recording medium storage case. It is housed in a case body that covers one side and opens the opposite side, and has an opening for recording and reproducing information on the recording side of the case body, and the portions of both sides of the case body that include the opening are used as the case body. This information recording medium storage case is characterized in that it is formed lower than the main surface of the main body, and a shutter is slidably attached to the lower part.

[Embodiments of the Invention] The present invention will be described in detail based on embodiments illustrated in FIGS. 1 to 3.

FIG. 1 is an exploded perspective view of the information recording medium storage case.

The approximately rectangular case body 11 has a circular recess 12 for storing a disk-shaped recording medium, and the recess 12 has an approximately circular center and a rectangular opening 13 extending laterally from the center. is provided. Note that a stepped portion 14 is provided around the substantially circular center, and is higher than the bottom surface of the recessed portion 12 . Further, a part of the case body 11 serves as a sliding part 16 on which the shutter 15, which is a combination of a rectangular flat shutter member 15a and a U-shaped shutter member 15b when viewed from the side, slides. is also lower.

As shown in FIGS. 2 and 3, an information recording medium is placed in the circular recess 12 with the recording side facing down, and the sliding portion 16
A shutter 15 consisting of two shutter members 15a and 15b is assembled with the case body 11 in between, and both shutter members 15a and 15b are bonded together using an adhesive or the like. Note that when the information recording medium is placed, the stepped portion 14 around the opening 13 comes into contact with the non-recording portion of the information recording medium.
The recording portion of the information recording medium does not come into contact with the bottom surface of the recess 12, and there is no risk of scratches or the like on the medium surface.

FIG. 2 shows a state in which the shutter 15 is closed, and the shutter member 15a of the shutter 15 closes the opening 13 located on the back side of the case body 11, and the recording surface of the information recording medium is passed through the opening 13. Prevents scratches etc. on +h
I'm L.

FIG. 3 shows a state in which the shutter 15 is open when installed in an information recording session reproducing apparatus. When the storage case is attached to the information recording and playback apparatus, the shutter 15 moves in the direction of arrow A and the recording surface of the information recording medium is exposed from the opening 13. Then, an optical pickup (not shown) is operated from below to record and reproduce information.

[Effects of the Invention] As explained above, the information recording medium storage case according to the present invention covers only the recording surface of the information recording medium and leaves the opposite non-recording surface open, and the lower part of the case body Attach a shutter to the part.

The thickness of the storage case can be brought closer to the thickness of the information recording medium, which can contribute to miniaturization of information recording and reproducing devices.
