Abstract

PURPOSE:To enhance operability when a disk is used by discharging the corresponding disk tray by the energizing force of a spring member at the time of the release of a lock member. CONSTITUTION:Lock members 18a-18e having protruding parts 17 are formed to both side surfaces of trays 13a-13e at the different positions corresponding to respective press members 14a-14e at every trays 13a-13e in such a state that the trays 13a-13e are inserted and have elasticity in an outward direction. When the trays 13 are discharged, by pushing in the press members 14a-14e corresponding to the desired trays 13a-13e in an outer case 11 on both sides thereof, the engagement of the protruding parts 17 of the lock members 18a-18e corresponding to the press members 14a-14e is released and the tray 13 concerned is discharged from an insert port 12 by the propelling force of a spring 19. When each tray is inserted, by pushing the tray 13 in the case from the insert port 12, each look member 18 is once depressed inwardly to pass through the insert port 12 and again expands outwardly at the position of each press member 14 and the protruding part 17 is engaged with a recessed part 22 to mount the tray.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc storage case for storing an information recording carrier such as an optical disc.

[Conventional technology] Conventionally, optical discs such as compact discs usually have 1
It is stored in an encyclopedia storage case.

In FIG. 7, a center presser 4 is provided at the center of a circular concave disk mounting portion 2 provided in the case body 1 with a spacer 3 in between, and the center hole of the disk D is connected to the center presser 4. They are fitted and supported by the spacer 3 so that the recording area portion of the disk D does not come into contact with the disk mounting section 2. Further, a pin 5 is provided at the side end of the case body 1, and an end of the upper cover 6 is engaged with the bottle 5, so that the upper cover 6 can be opened and closed with respect to the case body 1.

FIG. 8 shows another conventional example, in which when the diameter of the disk D is smaller than the above-mentioned disk D, a part of the paper cover 7 is attached to the back side of the case body 1, and the paper cover 7 on the front side is opened and closed. The aim is to reduce costs by making it flexible.

However, in such a disc storage case, when using multiple discs in succession, the cover must be opened and closed each time the disc is used, and it is unstable and space-efficient when carried all at once. There is an operational problem.

[Object of the Invention] An object of the present invention is to provide a disc storage case that solves the conventional problems and improves operability when using a plurality of discs.

[Summary of the Invention] The gist of the present invention to achieve the above-mentioned object is: - A disc storage case in which a plurality of disc trays are stacked and inserted and stored in a box-shaped outer case with an insertion opening on the side. A lock member that fixes each of the disc trays to the outer case when stored, and a spring member that biases the disc tray in the ejection direction, and when the specific lock member is released, the biasing force of the spring member responds. The disc storage case is characterized in that the specific disc tray is ejected.

[Embodiments of the Invention] The present invention will be described in detail based on embodiments illustrated in FIGS. 1 to 6.

1 to 5 show a first embodiment, in which a box-shaped outer case 11 is provided with an insertion slot 12 with one side open, and trays 13a to 13e holding disks D are stacked and stored. has been done. Further, pressing members 14a to 14e for releasing the tray lock, which will be described later, are arranged along one side of the outer case 11. Each of the flat trays 13a to 13e includes
As shown in FIG. 2, a circular hole 15 having a diameter approximately equal to the outer diameter of the disk D is formed, and a ring-shaped step portion 16 having a diameter larger than the outer diameter of the recording area of the disk D is formed along the inner surface of the hole 15. is provided so that the non-recording area on the outer periphery of the disk D is supported by the stepped portion 16. Furthermore, locking members 18a to 18e having convex portions 17 are provided on both sides of the trays 13a to 13e for each tray 13a to 13e.
It is molded at different positions corresponding to 4a to 14e and has elasticity in the outward direction. A spring 19 and a stopper 20 are integrally molded in the inner parts of the trays 13a to 13e, and as shown in FIG.
1 is provided and has elasticity in the vertical direction.

4 and 5 show enlarged cross-sectional views of the main parts of the tray 13a attached to the outer case 11, and as shown in FIG. 4, both sides of the outer case 11 have recesses 22 inside. The pressing member 14a is molded.

It has elasticity in the direction parallel to the tray 13a, and the convex portions 17 of the locking member 18a fit into the four portions 22 to regulate the insertion direction and the vertical direction of the tray 13a. The same applies to the trays 13b to 13e. Further, as shown in FIG. 5, the springs 19 of the trays 13a to 13e contact the rear inner wall surface of the outer case 11 in a contracted state to remove looseness between the trays 13a and the outer case 11. It is designed to store the propulsive force during ejection. Holes (not shown) are provided in the inner walls of the lower surface of the trays 13a to 13e and the upper surface of the outer case 11, and when the adjacent lower tray 13 is ejected, the stopper 2
The convex portion 21 of 0 engages with this hole to prevent the tray 13 from being completely removed from the outer case 11.

In the above configuration, when discharging the tray 13, the pressing members 14a to 14e corresponding to the desired trays 13a to 13e are pressed.
By pushing in from both sides of the outer case 11, the locking members 18a to 18 corresponding to the pressing members 14a to 14e are released.
The fitting of the convex portion 17 of e is released, and the corresponding tray 13 is ejected from the insertion port 12 by the driving force of the spring 19. Furthermore, when storing the tray, by pushing the tray 13 through the insertion opening 12, the locking member 18 is once recessed inward, passes through the insertion opening 12, and expands outward again at the position of the pressing member 14, so that the protrusion 17 is inserted into the recess 22. They fit together and the installation is complete.

FIG. 6 shows a second embodiment, in which a recess is provided at the rear end of the tray 13, and a spring 23 protrudes into the recess with a continuous five-shape shape to disperse stress concentration. A pedestal 24 is provided at a portion of the inner wall that corresponds to the spring 23. This eliminates the need for the spring 23 to protrude to the rear of the tray 13.

Improves space efficiency.

[Effects of the Invention] As explained above, the disc storage case according to the present invention has the advantage of compactly storing a plurality of discs, having a simple component structure, and being highly portable and easy to operate.
