Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette containing a tape such as a magnetic tape, and more particularly to a tape cassette storage case used for storing and transporting a commercial tape cassette such as a video cassette.

[0002]

2. Description of the Related Art Generally, magnetic tape cassettes are handled in storage cases for storage and sale.
As shown in FIG. 6, this case has a rectangular case body a for accommodating a tape cassette, a rectangular cover c integrally connected with a hinge b so as to be openable and closable, and an engagement between the case body and the cover. What provided the locking part d in the surface is used frequently.

[0003]

In the conventional case for storing a tape cassette used in business, even if there is an engaging portion, the frictional resistance is low, and it is weak in impact resistance due to settling or scraping, and the lid body is not used. The tape cassette of the contents is opened immediately,
It tends to pop out of the case or lose its dust-proofing effect, especially with professional tapes that are heavy and open during transportation, which can hinder them. In addition, the operability is extremely complicated and deteriorated, and the other finger hangs on the lock end when the lock portion is pressed, so that the lock mechanism does not operate, thereby causing a problem in handling. The present invention seeks to eliminate these disadvantages.
A case with high safety for handling business tapes, one-touch opening / closing operation is possible even when the lock strength is increased, making handling operability extremely easy and good. It is an object of the present invention to provide a highly safe tape cassette storage case having a simple configuration and an inexpensive form.

[0004]

According to the present invention, there is provided a lid body 1 which is integrally connected to a case body 3 capable of accommodating a tape cassette by a connecting portion 2 so as to be openable and closable.
It provided relative to the engaging portions 4, 4 _1, temporarily fixing locking the lid 1 in the case body 3 and the lid body 1, the front wall 1 the lid 1 ₁

[0005]

SUMMARY OF] In tape cassette storage case, when slide guide flange 7 along the lock operation member 10 in the front wall 1 ₁ of the lid 1 into the guide hole 5, to slide while pressing the spring 9 while unlocked as a state for opening the lid 1 the locking claw portion 8 at the end is disengaged from鉤穴₆₁ of the case main body 3, it is expanded by the connecting portion 2 Raising the lid body 1, the case body 3 can be taken out of the case. On the other hand, when the tape cassette is stored, if the lid 1 is inserted into the case body 3 and closed,
While front wall 3 ₁ of the case main body 3 is pushed against the inclined surface of the locking claw portion 8, the lock operation member 10 is has been locked fitted in the locking window hole 6 is pushed. In this case, the guide protrusion 7 of the lock operation member 10 moves is guided to the guide hole 5, the locking pawl 8 is locked by being inserted into鉤穴6 _1, with one touch closing operation the lid 1 It will be locked and the front wall 11 of the lid ₁
While peripheral side wall portion is fitted polymerized peripheral side wall including a front wall portion 3 ₁ of the case main body 3 containing, and engaging portions 4, 4 ₁ is temporarily fixed is engaged securely lid 1 Can be fixed, and the tape cassette is stably stored and stored in the case body 3,
It can be transported and handled.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 5, an embodiment of the present invention will be described. provided, provided the case body 3, a convex portion for temporarily fixing locking the lid 1, relative to the engaging portions 4, 4 ₁ of recesses on the opposing surface of the side wall portion of the case body 3 and the lid 1 in the tape cassette storage case has the form a guide hole 5 along the front wall portion 1 ₁ in its longitudinal direction of the lid 1, and a frame-shaped partition wall 1 ₂囲成a portion of the guide hole 5 and internally provided, in the frame-shaped partition wall 1 ₂ provided with a locking window hole 6, wherein a guide protrusion 7 which engages with the guide hole 5, whereas provided on a side surface the locking window hole 6 Operating member 10 having a lock claw portion 8 to be engaged with the lock member and a spring 9 provided on the other side surface. The slidably fitted deploy the front along the wall portion 1 ₁ in the frame-like partition wall 1 in _2, the locking member the locking claw portion 8 is a鉤穴₆₁ is inserted and latched supported This is a cassette storage case provided in the case body 3.

The lock operating member 10 in this embodiment may be made of PP resin similar to the material of the case. However, the open / close operation with low frictional resistance is smooth, and the guide projection 7 and the lock claw portion are made of POM resin. The spring 9 may be integrally formed with the guide hole 8, and the head of the guide projection 7 may be easily fitted into the guide hole 5. The lock claw portion 8 has an inclined surface and is provided at one end of the lock operation member 10. The lock claw portion 8 has a form in which the spring 9 serving as a pressing portion bends and the lock claw portion 8 is easily released. Considered.

The lock operating member 10 is provided with a plate-like spring 9 which is urged in one direction, for example, leftward, of the guide hole 5 so that it can be locked with one touch when the cover 1 is closed. but if not requested one-touch operation, it is possible to lock engagement if brought into fitting the locking pawl 8 by sliding the lock operation member 10 after closing the鉤穴6 _1. Further, the guide projection 7 of the lock operation member 10
Is a plate-like member having a flat surface along the front wall portion 3 ₁ of the case main body 3 on the surface side, Yes and easy to operate by providing an uneven surface for non-slip surface, if necessary operation direction can or providing the display unit 11 of the arrow, by providing in a state of being fitted to the front wall 1 ₁ of the guide hole 5 of the lid 1, the front wall portion 1 ₁ and the guide flange 7 Togahobo It is flat and flat, and there is no obstruction on the outside of the case, which makes it easy to handle and contributes to the quality improvement of the case.

The case body 3 and the lid 1 are formed by projecting a peripheral side wall including front walls 3 ₁ , ₁₁ to be fitted, and the front wall 11 of the lid ₁ is formed. An uneven portion 12 and a rib 13 which can partially fit in the wall are formed in the wall, and corresponding locking projections are provided to prevent dust and prevent deformation during molding, and to prevent misalignment with the lid 1. There is a case of structure. Further, the lock window hole 6 may be provided on a side wall of the case, into which the claw 8 is inserted, and may have an inclined surface or a tapered surface guide for guiding the claw 8. May be automatically locked when the is closed.
