Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a storage case for storing a tape cartridge with a front lid so that the locking means of the front lid of the tape cartridge is not adversely affected.

[Conventional technology]

As a small tape cartridge for video, there is a tape cartridge (VHS-C type) shown in FIG. This is front lid 1
0 rotates around the shaft 13 to switch between the open posture and the closed posture, and is held by itself in each posture position. Specifically, a slider 51 that is pressed and urged by a U-shaped leaf spring 50 is provided on the lateral side wall of the main body case 1. By pressing the protruding end of the slider 51 against the side wall edge 52 of the front lid 10 that intersects at right angles, The front lid 10 is held in the open / closed position. For example, it is found in Japanese Utility Model Publication No. 59-20489.

In the tape cartridge as described above, the front lid 10 is merely held in the open / closed position at each position, and the front lid 10 is not positively locked in the closed position. Therefore, the user can open and close the front lid, and in some cases, the front lid 10 may be unexpectedly opened during handling and the tape 4 may be damaged.

In order to prevent such damage to the tape 4, the front lid 1
It is required to securely hold 0 in the closed posture.

Therefore, as shown in FIG.
Can be considered to be closed. It should be noted that the lock member 15 is itself formed in a plate shape and has a spring function. The lock member 15 is arranged on the inner surface of the side wall 21 of the main body case 1, and
The lock claw 17 provided on the front lid 10 engages with the engaging portion 20 provided on the inner surface of the side wall 12 of the front lid 10 to hold the front lid 10 in the closed posture. Then, in order to disengage the lock claw 17 from the engaging portion 20 and open the front lid 10 so that the front lid 10 can be operated, a release piece 18 is provided on the lock member 15. The point is that the window 22 that opens at 21 projects outside the case.

It is conceivable that this type of tape cartridge A can be stored by storing it in a storage case 30 of the form shown in FIG. 2, for example. The storage case 30 is composed of a body 31 and a lid 32, and has a pocket 35 into which the tape cartridge A is inserted and loaded.

[Problems to be solved by the invention]

The release piece 18 is added to the conventional storage case 30 as described above.
When the tape cartridge A which is exposed to the outside of the case is stored, the releasing piece 18 contacts the inner surface of the peripheral side wall 43 of the pocket 35 and is pushed inward of the case as shown in FIG. The lock member 15 including is always maintained in a state of being flexibly deformed in the disengagement posture.

Therefore, when the tape cartridge A is taken out from the storage case 30 during use, the front lid 10 is unexpectedly opened and the tape is damaged.

Further, when the storage state is long, the lock member 15 is creep-deformed, and the front lid 10 cannot be locked in the closed posture in the next use, or the lock engaging force is insufficient and the front lid 10 is easily opened and operated. It is expected that the lock member 15 will not function properly due to, for example, being lost. Particularly, it is remarkable when the lock member 15 has a spring function and is made of a plastic material having elasticity.

The present invention has been proposed to solve the above problems.

An object of the present invention is to prevent the lock member 15 from being deformed by creeping in a state where the tape cartridge A is stored in the storage case, and keep the front lid 10 locked in the closed posture at all times.

[Means for solving problems]

That is, according to the present invention, a front cover 10 that covers the front surface of the main body case 1 is pivotally attached to the main body case 1 so as to be freely opened and closed.
A lock member 15 for abuttingly engaging a part of the front lid 10 to hold the front lid 10 in a closed posture is disposed on the inner surface of the lateral side wall 21 of the main case 1. Side wall 2
1 has a release piece 18 that is exposed to the outside of the case through a window 22 provided on the front end side of the 1. The release piece 18 is urged so as to project to the outside of the window 22 from the outside of the case. The target is a tape cartridge in which the engagement between the lock member 15 and the front lid 10 is released by pushing the release piece 18 inward of the case.

Thus, the storage case of the present invention comprises the body 31 and the lid 32, and the base end side of the lid 32 is supported on the rear end side of the body 31 via the shaft 33 so as to be openable and closable in the vertical direction. 31 has a pocket 35 on the rear end side of the inner surface of the bottom wall 34 of which the front end portion of the tape cartridge A can be removably mounted from the front side. A release recess 46 is formed on the inner surface for preventing the release piece 18 on the side of the tape cartridge A from coming into contact with the peripheral side wall 32 and being pushed inward of the case. .

[First Embodiment] FIGS. 1 to 5 show a first embodiment of the present invention.

In FIG. 1, the target tape cartridge A has a pair of tape reels 2 and 3 inside and on the left and right of a main body case 1 in which upper and lower cases are joined together to form a lid. Tape 4 is

Is outside the case. When the tape cartridge is loaded in the deck, the lock member 15 is pushed into the case through the release piece 18 by the operation member on the deck side, whereby the lock claw 17 is flexed and deformed inwardly of the case, and the engaging portion. Get out of 20.

FIG. 2 shows a main case 30 for accommodating the tape cartridge A of the above-mentioned form.

The storage case 30 includes a body 31 and a lid 32.
2 is supported so as to be vertically swingable about the shaft 33. The body 31 has a pocket 35 at the rear end side of the inner surface of a bottom wall 34 of the body 31, into which the front end portion of the tape cartridge A can be detachably mounted from the front side. This pocket 3
A shaft hole 37 for supporting the shaft 33 on the left and right peripheral side walls 43
Is transparently installed. The lid 32 is formed by projecting a front end wall 40 and left and right side walls 41 from three sides around the upper wall 39, and in the closed state, the upper wall 39 is adjacent to the pocket 35 and the bottom wall 34 of the body 31.
Parallel to.

The pockets 35 are provided on the left and right peripheral side walls 4 which are erected from the bottom wall 34.
3, 43, a rear end wall 44, and an upper peripheral wall 45 parallel to the bottom wall 34, and the left and right widths and the vertical heights thereof are slightly smaller than the left and right widths and the vertical heights of the tape cartridge A by margins. It is set large.

In order to prevent the release piece 18 protruding from the case side wall 21 of the tape cartridge A from contacting the peripheral side wall 43 and being pushed inward in the case when the tape cartridge A is stored in the pocket 35, One side wall 43
A relief recess 46 is formed on the inner surface of the.

3 and 4, the relief recess 46 is formed as a groove having a U-shaped cross section, which is wider than the vertical dimension of the release piece 18, and extends from the opening edge of the peripheral side wall 43 toward the bottom end of the pocket. Formed in parallel. Further, even when the tape cartridge A is in contact with the inner surface of the peripheral side wall 43 as shown in FIG. 4, the groove depth is set so that the projecting end of the releasing piece 18 does not contact the groove bottom.

At this time, in the state where the tape cartridge A is accommodated in the pocket 35, the release piece 18 of the lock member 15 faces into the escape recess 46, so that the release piece 18 contacts the peripheral side wall 43 of the pocket 35 and is locked. It is not saved in the released state.

[Second Embodiment] FIG. 6 shows a second embodiment of the present invention. In this case, the relief recess 46 is formed as a trapezoidal recess on the upper half wall surface of the inner surface of the peripheral side wall 43. In this way, the recessed shape of the relief recess 46 and its cross-sectional shape can be freely set as required. In some cases, with the tape cartridge A completely mounted in the pocket 35, the relief recess 46 having a shape similar to the release piece 18 may be formed only at a portion facing the release piece 18. That is, the escape recess 46 does not necessarily have to be formed with the opening edge of the peripheral side wall 43 as the starting end.

[Third Embodiment] FIG. 7 shows a third embodiment of the present invention. When the tape cartridge A is inserted into the storage case 30, the upper and lower surfaces or the front and back directions may be mistakenly reversed. Thus, even when the tape cartridge A is accommodated in the different loading directions, the unlocking piece 18 is prevented from being unlocked.

Specifically, while forming escape recesses 46, 46 on the left and right peripheral side walls 43, 43 of the pocket 35, respectively,
The escape recesses 4 are also formed on the inner surfaces of the left and right side walls 41 of the lid 32.
6a was formed. Then, the latter escape recess 46a is formed with the lower edge side of the left and right side walls 41 as the starting end.

[Another embodiment example]

In the illustrated example, the reference numeral 31 is referred to as the body and the reference numeral 32 is referred to as the lid, but it goes without saying that they may be referred to in reverse.
In that case, for example, a form in which the body 32 is covered with a flat plate-shaped lid 31 having no pocket 15 is possible, but in this case, at least one side wall 41 of the body 32 is formed with the escape recess 46 of the problem. It may be.

Further, the present invention is particularly effective in the case where the lock member 15 has a spring property of elastically deforming, but it is not necessarily limited to this. For example, a configuration in which a separate spring member abuts on the lock member 15 is also included. Also when the lock member 15 having a spring property is used, it may be U-shaped or U-shaped in a front view or a plan view, and may be made of metal. In any case, the lock member 15
With respect to, the shape and the like are not limited.

[Effect of device]

According to the storage case of the present invention, when the tape cartridge A is stored, the release piece 18 on the side of the tape cartridge A, which is exposed to the outer surface of the storage cartridge A, is arranged to escape into the recess 46, so that the lock member 15 is locked. It is possible to prevent the device from being stored while being operated in the release posture. As a result, even if the lock member 15 is left in the housed state, the creep deformation of the lock member 15 can be reliably prevented. Since the front lid 10 can be stored in a state where it is always held in a locked state, it is possible to surely prevent the front lid 10 from being accidentally opened to damage the tape 4 when taking it out.
