Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a disk case housing an optical disk, and more particularly to an improvement of a disk case that allows data to be read while the disk is housed.

[Summary of the idea]

The present invention relates to a disk case, and in particular, in a disk case that allows reading data recorded on or writing data to an optical disk when the optical disk is housed, the pick-up guide groove can be opened when the disk is not moved. It has a shielding member, that is, a U-shaped shutter, to prevent dust from entering through the central hole into which the spindle for driving the disk is inserted. This makes it complicated to put in and take out the disk, so the shutter is constructed with a leaf spring, and the shutter is placed on the side where the upper and lower shells are pivoted so that they can be opened and closed, so that the upper and lower shells can be easily opened and closed together with the shutter. It provides a disk case.

[Conventional technology]

When writing or reading high-density information on an optical disk, etc., it is preferable to read or write while the disk is housed in the casing in order to avoid dust, fingerprints, scratches, etc. on the disk. There is also a device that reads and writes to a disk without being housed in a casing, and in order to be compatible with this device, it is necessary to be able to easily remove the disk from the casing in which it is housed. On the other hand, when the disk is housed in the casing, there is a center hole for inserting a spindle to drive the disk, and a pick-up for reading data from the disk and writing data to the disk, for guiding it in the direction of the disk's radius. An opening consisting of a guide groove is bored in the casing,
Generally, a shutter is added to cover these openings when storing or carrying a disk.

[Problems to be solved by the invention] In the disk case with a shutter of the conventional configuration described above, the shutter configuration has a roughly U-shape that integrally shields the upper and lower shells of the casing. It is preferred and widely used because of its cost. This has resulted in the disadvantage that it is difficult to easily remove or insert the disk from the casing.

[Means for solving problems]

The present invention was devised in view of the above-mentioned drawbacks, and aims to provide a disk case in which disks can be easily inserted and removed.The present invention is based on a casing in which disks are rotatably disposed within the upper and lower shells. The upper shell is provided with a center hole for inserting a clamp, and the lower shell is provided with an opening consisting of a spindle insertion port and an optical pickup guide groove, and the opening is configured such that it can be shielded by a movable leaf spring-like shutter. The present invention is achieved by a disk case characterized in that the above-mentioned shutter is provided on the side where the shell is pivotally attached to be openable and closable.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a plan view of the disk case of the present invention, FIG. 2 is a side sectional view of the disk case of the present invention in an open state, and FIG. 3 is an external view of the shutter.

In FIGS. 1 and 2, reference numeral 1 indicates a disk case as a whole, and a box-shaped casing is constructed by opening and closing upper and lower shells 1a and 1b. The upper and lower shells 1a and 1b of the casing have a center hole for inserting the clamp part and a center hole for inserting the spindle, and the lower shell has an opening for guiding the optical pickup along the radial direction of the disk. A section 2b is provided. As a shutter for simultaneously shielding the center hole and the guide groove, a shutter 5 made of a plate spring having a roughly U-shaped shape when viewed from the side is used to create a center hole for clamp insertion in the upper shell and a hole in the lower shell. The center hole 2a of the insertion hole in the spindle and the opening 2b forming the guide groove for guiding the optical pickup are simultaneously covered. For this purpose, the shutter 5 is slidably fitted to the upper opening/closing shaft side in FIG. The lower side of the casing 1 in FIG. 1 and the right side of the casing 1 in FIG. It is designed to lock when closed.
At the other end, grooves 7a and 7b are formed in the upper and lower shells 1a and 1b, and the cut-out pieces 6a and 6b of the shutter 5 formed by plate springs are engaged with the grooves 7a and 7b, and the arrows A
The shutter is configured to be able to move along the direction.

With the above-described structure, when the shutter 2 is moved manually or mechanically to the left in FIG. It becomes readable. In the case of disk replacement, the upper shell 1a can be opened together with the shutter by manually raising it, and the disk can be replaced and closed by the spring force of the shutter 5 when the hand is released.

[Structure of the idea]

As described above, the present invention has a structure in which the upper and lower shells are prevented from opening by the elasticity of the shutter, so that the disk case can be easily opened and closed, and the disk can be easily replaced.

Claims (1)

[Scope of utility model registration request] In a disk case that has an opening on the surface of a casing in which disks are rotatably arranged in an upper shell and a lower shell to read information recorded by rotating the disk, the opening is connected to the surface of the disk case. A shutter that slidably fits along one side wall to open and close, and an engaging portion that prevents lateral displacement between the upper shell and the lower shell, and the elasticity of the shutter allows each shell to move in the vertical direction. A disk case characterized in that it is configured to prevent opening of the disk case.
