Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to recording tapes, video tapes, other cassettes, compact discs, etc.
Below, they are collectively referred to as "cassettes". ) Is a case for storing.

[0002]

Conventional cassette case is such as shown in FIG. 1, it has several disadvantages such as:
There Ru. When putting the cassette in the cassette case, it is necessary to put the tape opening end first in the case groove. And when the lid is closed , the protrusion A in the lid is the hole B of the cassette.
Lid only cassette case when combined with somewhere south closed smoothly, Wakashi will not be capped in the wrong direction on the location transfected <br/> cassette case of the cassette, which is very inconvenient. When removing the cassette from the cassette case, it is usually bothersome to open the cassette case lid with both hands. Moreover, since the cassette case is an open type, it will easily fall if you are not careful, and it may adversely affect or destroy the cassette. Such inconvenient when trying to retrieve the cassette into operation in the like of the automobile, is where you often experience.

[0003]

In view of the drawbacks of the conventional cassette case, the present inventor has completed the present invention through repeated research, development and testing. Mainly using the structure of two mutually exercise, and that the hand part of the structure therein utilizes exerting a closing action on the lid of another structure
By, it is its primary purpose of obtaining a cassette case which can be opened and closed with one hand.

Another object of the present invention is to provide a cassette case in which a recording tape or a video tape can be taken out and put in easily and safely.

[0005]

A cassette case according to the present invention includes a first structure which is slidably assembled with each other.
And a second structure. The first structure is generally

Provided to connect the rear ends of a pair of sliding rails
It consists of a rear wall. The second structure is also the first structure.
A space for storing a cassette inside when combined with
Slidable back and forth on the first structure so as to define
Be combined.

A second wall is formed on the inner surface of each side wall of the first structure.
Long groove that slidably receives the corresponding sliding rail of the structure
Are provided respectively. The open / close lid corresponds to the first structure.
A pair of side wall portions constituting part of the side walls respectively that, the both
A front wall provided so as to connect the front ends of the side wall parts to each other.
And an arcuate shape on the inner surface of at least one of the both side wall portions.
A groove is formed. At least the sliding rails of the second structure
Also, at one front end, engage with the arcuate groove formed on the opening / closing lid.
A protrusion is provided for releasable engagement.

The second structure is relative to the first structure.
When the sliding rail is slid forward, the sliding rails should
The second structure relative to the first structure.
And the same position on the inner surface of each side wall of the first structure.
2 The structure is installed on the corresponding outer surface of each sliding rail.
The first structure is formed by fitting the broken projection and the recess.
Engage between the body and the second structure, and in front of each sliding rail
The protrusions on the edges engage with the corresponding arcuate grooves on the lid.
Locks the pivoting of the lid.

The cassette case according to the invention also comprises a first
Rays are provided along the top wall side edges of each side wall of the structure.
And the front and rear sides provided along the edge opposite to the edge.
A long groove between a pair of rails that are separated from each other in the direction
And at least one of the pair of rails front and rear
The passages for slidably holding the slideways of the second structure
It can also be provided on the moving rail.

The cassette case according to the present invention is
Each extension portion extending rearward from the side wall portion is provided with the first structure.
The opening / closing lid is connected by being pivotally mounted on each side wall of
The front end of each sliding rail of the second structure is arcuate from the bottom wall.
Formed to stand up to, and the upper end of each sliding rail
Make the rim low so that it does not interfere with the pivoting of the lid.
Abut on the front lower step that is made and the extension of the opening and closing lid.
To prevent the sliding rails from moving forward.
It can also be formed separately from the rear high step formed
It

[0010]

[Function] When the cassette case is closed, the first structure
Projections and recesses on each side wall of the structure and each sliding rail of the second structure
Positional relationship between the first structure and the second structure by fitting the parts
To fix. At the same time, the protrusion on the front end of the slide rail
It engages with the arcuate groove of the opening / closing lid to prevent the opening / closing lid from pivoting.

With one hand, the top and bottom of the rear end of the cassette case
Hold and move the second structure forward relative to the first structure
When you slide it, the opening / closing lid will be
It is pivoted toward and the case is opened. At this time,
The protrusion on the front end of the tool pushes up the edge of the arc-shaped groove on the lid.
Promotes pivoting of the lid. In this state, open the cassette
The first structure and the second structure on the bottom wall of the second structure.
To slide the structure so that it is at the same position relatively
More stored.

The relative movement of the second structure in the front-back direction is
The sliding range of the rail of the first structure is set to the sliding range of the second structure.
The first structure and the second structure
If the structure is inadvertently separated and you drop the cassette
To avoid. The relative forward movement of the second structure is
For contact between the rear high step of the moving rail and the extension of the opening / closing lid
Therefore, it is also limited.
