Description

[Detailed explanation of the idea] This invention relates to a tape cassette storage box.

a storage box body having a recess for receiving a tape cassette; a storage box body that covers the opening of the recess of the storage box main body and stores the tape cassette disposed in the recess of the storage box main body in the recess; 1 position and
The tape cassette is connected to the storage box main body so as to be rotatable between a second position where the tape cassette is separated from the opening of the recess in the storage box main body and allows the tape cassette to be removed from the recess. a lid; provided on the storage box main body, disposed in a direction intersecting the rotation center line of the lid, and engaged with a pair of reel hubs of a tape cassette disposed in a recess of the storage box main body; A tape cassette storage box is already known which includes a pair of detent members for preventing rotation of a pair of reel hubs.

A conventional tape cassette storage box is used for a microcassette, which is a type of tape cassette, and the height of each pair of rotation prevention members is equal. When the lid has a kangaroo pocket member, when the lid is placed in the second position and tilted with respect to the storage box main body, one pair of detent members of the storage box main body and one pair of micro cassettes is disengaged from the reel hub. At this time, unless the angle of inclination of the lid with respect to the main body of the storage box is relatively large, the engagement between the pair of detent members of the tape cassette storage box and the pair of reel hubs of the microcassette cannot be released.

Furthermore, even if the lid does not have a kangaroo pocket member, in order to release the engagement between the pair of detent members on the storage box body and the pair of reel hubs on the microcassette, tilt the microcassette with your fingers. It must be ensured that the microcassette has a relatively large angle of inclination with respect to the housing body.

However, since the lid tends to return to the first position due to gravity, when attempting to remove the microcassette from the recess in the storage box main body or when attempting to store it in the recess in the storage box main body, the lid tends to return to the first position due to gravity. This becomes an obstacle to tilting the microcassette with respect to the main body of the storage box so as to have a large tilt angle.

That is, the work of accommodating the microcassette into the recess of the storage box main body and the work of removing it from the recess of the storage box main body become complicated.

This invention was made based on the above-mentioned circumstances, and its object is to provide a tape cassette storage box that makes it easy to insert tape cassettes, of which microcassettes are one type, into recesses in the storage box body and to remove them from the storage box body.

Examples of this invention will be described below with reference to the drawings.

FIG. 1 shows a tape cassette storage box 10 and a tape cassette storage box 1 according to an embodiment of the invention.
A microcassette 12 is shown stored at 0.0. The tape cassette storage box 10 includes a storage box body 14 having a recess for receiving a microcassette 12. The storage box body 14 has a lid 16

A first position covering the opening of the recess (i.e., a closed position) as shown by the dashed line, and a second position (i.e., a closed position) spaced from the opening of the recess as shown by the solid line in FIGS. 1 and 2. That is, it is rotatable between the open position and the open position. As shown in particular detail in FIG.
Additionally, a kangaroo pocket member 18 is provided for movement between a first position (closed position) and a second position (open position). In order to hold the microcassette 12 in the kangaroo pocket member 18, push the microcassette 12 in the direction of arrow A along the back surface of the lid 16 which is placed in the second position (open position) as shown in FIG. Bye. In order to remove the microcassette 12 from the kangaroo pocket member 18, pull the microcassette in the direction opposite to arrow A along the back surface of the lid 16 which is placed in the second position (open position) as shown in FIG. 12 should be moved. When the lid 16 is in the second position (open position), the microcassette 12 is not placed in the recess in the storage box body 14, and the microcassette 12 is not placed in the recess in the storage box body 14. It can be accommodated and removed from the recess of the storage box main body 14.

In this embodiment, the pivot axis 20 of the connecting means of the lid 16 is connected to the storage box body 1 as shown in FIG.

Further, in this embodiment, on the outer surfaces of the left wall portion 30 and right wall portion 32 of the kangaroo pocket member 18, substantially hemispherical protrusions 34 protruding into the external space are formed, as shown in FIGS. 1 and 2. has been done. The respective rotation loci of the left wall portion 30 and right wall portion 32 of the kangaroo pocket member 18 when the lid 16 rotates between the first position (closed position) and the second position (open position) are as follows. , are parallel to the inner surfaces of the left wall 22 and right wall 24 of the storage box body 14, respectively. When the lid 16 is placed in the first position (closed position) as shown by the two-dot chain line in FIG.
Each of the two protrusions 34 engages with a recess 36 formed in the inner surface of each of the left wall 22 and right wall 24 of the storage box body 14, as shown in FIGS. 1 and 2. At this time, the microcassette 12 placed in the recess of the storage box main body 14 is isolated from the outside space by the lid 16 and the storage box main body 14.

On the inner surface of the bottom wall 38 of the storage box main body 14, a first
As shown in the drawings and FIG. 2, a pair of reel hub rotation prevention members 40 and 42 are provided.

The pair of reel hub rotation prevention members 40 and 42 are
They are spaced apart from each other in a direction intersecting the rotation center line of the rotation center axis 20 of the lid 16. In this embodiment, the pair of reel hub rotation prevention members 40 and 42 are spaced apart from each other in a direction substantially perpendicular to the rotation center line of the rotation center shaft 20 of the lid 16, as shown in FIG. has been done.

The pair of reel hub rotation prevention members 40 and 42 are
The lid 16 is held by the kangaroo pocket member 18.

It engages with a radial protrusion (not shown) provided on the inner circumferential surface of the reel hub 44 and prevents the pair of reel hubs 44 and 46 from rotating. Therefore, the tape cassette storage box 10
The micro cassette 12 stored in the tape cassette storage box 10 is moved by the pair of reel hubs 44 and 46 due to vibrations applied from the external space during transportation of the tape cassette storage box 10.
This prevents the magnetic recording tape 48 wound around the magnetic recording tape 48 from sagging. As a result, it is not only possible to eliminate one of the causes of wow and flutter, but also to prevent the magnetic recording tape 48 from being exposed to the outside space and being damaged through the window 50 for inserting the magnetic head of the pinch roller 1 of the microcassette 12. It can be prevented.

A pair of reel hub rotation prevention members 4 of this embodiment
0 and 42 have different heights, as shown in FIGS. 1 and 2. That is, the height from the bottom wall 38 of one reel hub rotation prevention member 40 located near the rotation center axis 20 of the lid 16 is greater than the height of the other reel hub rotation prevention member 42 on the side farther from the rotation center axis 20. The height from the bottom wall 38 is smaller than the height from the bottom wall 38. The above-mentioned height of the one reel hub rotation prevention member 40 is such that the one reel hub 44 of the micro cassette 12 disposed at the first position together with the lid 16
This is the minimum height that can reach a plurality of engagement protrusions (not shown) formed on the inner circumferential surface of and engage with the above-mentioned engagement protrusions (not shown).

By placing the lid 16 in the second position (open position), the pair of reel hubs 44 and 46 of the micro cassette 12, which is detachably held in the kangaroo pocket member 18, are connected to the pair of reel hubs 44 and 46 of the storage box body 14. Reel hub rotation prevention members 40, 42
Assume that the engagement of the

At this time, a conventional tape cassette storage box having a pair of reel hub rotation prevention members 40 and 42 having the same height as the present embodiment in which one height of the pair of reel hub rotation prevention members 40 and 42 is lower than the other height is removed. Compared to the above, in this embodiment, the angle of inclination of the microcassette 12 with respect to the bottom wall 38 of the storage box main body 14 when the engagement is released can be made smaller.

Therefore, in the tape cassette storage box of this embodiment, when the lid 16 is moved from the first position (closed position) to the second position (open position), the lid 16 is moved to the first position by gravity.
Even if you try to return to the position (closed position), the lid 16
When the lid 16 is placed in the second position (open position), the angle of inclination of the microcassette 12 with respect to the bottom wall 38 of the storage box body 14 can be made smaller than in the past. position) to the second position (open position), and the work of storing the microcassette 12 in the recess of the storage box main body 14 and the work of removing the microcassette 12 from the recess of the storage box main body 14 can be reduced. can be facilitated.
