Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette storage case, and more particularly to a tape cassette storage case suitable for use in a digital video cassette or the like.

[Prior art]

Up to now, as a storage case for a mini size DV (digital video) cassette, the same as a storage case for an ordinary compact cassette or an 8 mm cassette has been used.
A box-shaped main body having a size capable of accommodating a cassette mini size and a lid rotatably connected to the main body are used.

With the downsizing of the cassettes, the thickness of the front lid of these tape cassette storage cases has become thinner, and there is rattling between the case and the cassette, which cannot be stored safely, and the front lid can also be taken out and put in. It is easy to damage the cassette because it is held by the hand. Therefore, in addition to the case main body in which the main body part and the lid are integrated, an inner frame formed of a plastic thin plate in a box shape is attached to the case main body. The inner frame is welded to the bottom plate of the main body by ultrasonic waves or the like.
Such welding requires a process for welding and equipment for it, which has led to an increase in manufacturing cost.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to eliminate the equipment and process required for welding, and to attach the inner frame to the bottom plate of the main body at low cost. It is to provide a case.

[0005]

In order to solve the above problems, a tape cassette according to the present invention comprises a main body portion and a lid portion joined by a hinge, a first side plate erected on the main body portion, and a first side plate.
An inner frame having a recess for fitting in the side plate to accommodate the tape cassette, a locking piece erected on the bottom plate of the main body, and a locking hole provided in the inner frame. The locking piece was locked to.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a tape cassette storage case of the present invention will be described below with reference to FIGS. In the perspective view of the tape cassette storage case according to the present invention shown in FIG. 1, a tape cassette storage case 1 (hereinafter referred to as a storage case) includes a bottom plate 1a, four side first side plates 1b and first side plates standing upright there. Inner frame 2 fitted in the center of 1b
The main body 3 and the bottom plate 1a are provided on one side with a back plate 4 connected to the back plate 4 by a thin hinge 4a and a lid 5 connected to the back plate 4. The lid portion 5 is composed of a top plate 5a and three sided second side plates 5b provided upright on the top plate 5a.

A recess 1c for accommodating a cassette is provided at the center of the inner frame 2 of the main body 3, and four frame sides 2 constituting the inner frame 2 are formed.
Notches 2b for taking out the tape cassette 6 (hereinafter referred to as a cassette) are provided on the left and right frames of a. Further, a locking rib 2c is provided inside the side piece 2a to determine the insertion direction of the cassette.

A pair of engaging holes 1b1 are provided in the front frame of the first side plate 1b, and a hook 5c that engages with the engaging hole 1b1 is provided inside the second side plate 5b of the lid portion 5. . As shown in FIG. 2, the cassette 6 includes a pair of hubs 6a, a mouth portion 6b provided in front of the shell, and a lid 6c provided on the front surface of the shell so as to be openable and closable.

In the tape cassette storage case 1 of the present invention, in particular, the bottom plate 1a of the main body 3 is provided with a locking piece 7a having a locking claw 7b at the upper end as shown in FIGS. 4 (a) and 4 (b). The bottom plate 2d of the frame 2 is provided with a locking hole 8 into which the locking piece 7a is inserted. Further, by providing the slit 7c in the locking piece 7a, the locking piece 7a can be closed, and the locking in the locking hole 8 becomes easy.

The diameter a of the pillar portion 7d of the locking piece 7a is smaller than the diameter c of the locking hole 8 and the outer diameter b of the locking claw 7b is larger than the diameter c of the locking hole 8. The top surface of the locking claw 7b is tapered toward the tip. With this configuration,
When inserting the locking piece 7 into the locking hole 8 of the inner frame 2, the inner edge of the locking hole 8 can be inserted by narrowing the sliding column 7d along the taper. It opens to the outside to prevent the inner frame 2 from coming off. And the position where the locking piece 7a is provided is the position where the locking piece 7a is inserted into the mouse portion 6b of the cassette,
When the cassette 6 is stored in the recess 1c of the storage case 1,
The locking piece 7a enters the mouse portion 6b of the cassette 6 to allow compact storage.

FIG. 3 is a side cross-sectional view showing a state in which the tape cassette 6 is stored in the tape cassette storage case 1, inside the first side plate 1b standing on the bottom plate 1a of the main body 3 of the storage case 1. The end of the frame piece 2a of the frame 2 abuts in a pressed state due to its own elasticity, the abutting portion 2e of the inner frame 2 abuts the bottom plate 1a, and the locking piece 7a standing from the bottom plate 1a forms the inner frame 2 It is fitted in the locking hole 8 of. A pair of abutting portions 2e is provided on the lower side of the bottom plate 2d of the inner frame 2.

The cassette 6 is housed in the recess 1c of the inner frame 2, and the locking piece 7a is inserted into the mouth portion 6b of the cassette 6 to prevent rattling. Further, the locking ribs 2c provided on the side of the concave portion 1c of the frame piece 2a of the inner frame 2 are provided with the cassette 6
It is engaged with a locking groove 6d formed on the side surface of the cassette 6 and defines the insertion direction of the cassette 6.

[0013]

Since the tape cassette storage case according to the present invention is simply fitted when the inner frame is assembled to the main body, the step of ultrasonic welding is unnecessary, and the equipment therefor is also unnecessary, so that the production is small. Can be manufactured at cost.
