BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge storage case for a recording medium, and more particularly, to a protrusion protruding inward of the storage case on a peripheral wall of the cartridge storage case facing a side wall of the cartridge. The present invention relates to a cartridge storage case in which the convex portion is disposed at a position opposing a rotation axis of the lid and / or a sliding axis of the upper lid, and includes a convex portion and a peripheral wall of the cartridge storage case near the convex portion, a lid side wall, and an upper lid side wall. Further, the present invention relates to a cartridge storage case that can reliably hold a cartridge while preventing deformation and destruction of the cartridge.

[0002]

2. Description of the Related Art A cartridge stored in a cartridge storage case is a cartridge having a lid rotation axis on a side wall or a cartridge having a lid rotation axis and a sliding axis of an upper lid, and the cartridge storage case has a projection. The case where the portion is a position regulating rib will be described as an example. 14 and 15 schematically show a state in which a cartridge having a lid rotating shaft is stored in a conventional cartridge storage case.

[0003] The cartridge is, for example, a cartridge for a recording medium. In order to prevent foreign matters such as dust from adhering to the surface of the recording medium such as a magnetic tape, and to prevent the recording medium itself from being damaged, It has the following structure. That is, it has a front opening on the front surface of a cartridge body that houses a pair of reels wound with a magnetic tape, and has a bottom opening connected to the front opening on the bottom surface of the cartridge body. It is hung along. Further, the cartridge body has a lid whose front side can be freely opened and closed with a rotation shaft, and an upper lid slidably provided with a slide shaft. When this lid is rotated to the upper surface side of the cartridge body, or when the lid is slid and the lid is rotated to the upper surface side of the cartridge body, the magnetic tape stretched along the front opening is exposed. You.

In a cartridge having a lid rotation axis or a cartridge having a lid rotation axis and an upper lid sliding axis, the lid rotates relative to the cartridge body when the lid rotates or the upper lid slides. A gap is provided between the outside of the cartridge body side wall and the inside of the lid side wall, and between the outside of the cartridge body side wall and the inside of the upper lid side wall so as not to hinder movement, and the cartridge side wall, the lid side wall, and The side wall of the cartridge and the side wall of the upper lid are configured so as not to be in close contact with each other. At this time, as a means for providing a gap, for example, a method of setting the outer dimension of the cartridge body and the inner dimension of the lid and a method of setting the outer dimension of the cartridge body and the inner dimension of the upper lid so as to secure a desired gap, Alternatively, there are various means such as a method in which a step is provided on the rotating shaft of the lid and the sliding shaft of the upper lid to partially increase the outer diameter of the shaft, and the step is in contact with the outside of the cartridge side wall to secure a gap. .

A lock mechanism for preventing the lid from being accidentally rotated and a lock mechanism for preventing the lid from inadvertently sliding are provided on the side walls of the lid and the upper lid. A biasing mechanism for holding the cartridge in the closing direction and a biasing mechanism for holding the upper lid in the closing direction are provided.A space is provided between the cartridge body and the lid side wall, and between the cartridge body and the upper lid side wall. Is provided.
However, even in the case where such a gap or space exists, the rotating shaft and the sliding shaft have a portion that comes into contact with the cartridge body in order to reliably perform the operation.
And sufficient strength is secured.

When the cartridge having a gap or space between the cartridge main body and the lid side wall and between the cartridge main body and the upper lid side wall is dropped in a cartridge storage case or the like, the position regulating rib is moved to the cartridge main body. It is assumed that an impact load acts on the side wall of the cartridge except for the lid side wall and the upper lid side wall.

For example, as shown in Japanese Patent Application Laid-Open No. 8-282771, when the position regulating rib of the cartridge storage case is not disposed at a position facing the lid side wall and the upper lid side wall, the lid and the upper lid are located between the cartridge main body. It is in a state where it is possible to move (with rattling) within the range of the void or space. The shock load acting at this time acts on the lid and / or the upper lid as a force to deviate from the range of backlash. At this time, since the lid and the side walls of the upper lid are not effectively supported by the position regulating ribs of the cartridge storage case, the lid side walls themselves,
There has been a problem that cracks and breakage may occur at the corners of the upper lid side wall itself or around the lid side wall toward the cartridge front opening side.

Further, the load is concentrated only on the position regulating ribs facing the cartridge side wall in a range excluding the lid side wall and the upper lid side wall, and the load applied to each rib increases. Due to this load, there is a problem that the rib itself, the peripheral wall of the cartridge storage case near the base of the rib or the main body of the cartridge is damaged. Further, in order to avoid this problem, if measures are taken to increase the number of ribs and reduce the load applied to each rib, a problem arises in that the structure of the cartridge storage case becomes complicated.

Next, the position of the cartridge in which a gap or space exists between the cartridge body and the lid side wall and between the cartridge body and the upper lid side wall is regulated by dropping the cartridge in a cartridge storage case. It is assumed that the rib abuts on the lid side wall or the upper lid side wall, and an impact load acts on the lid side wall or the upper lid side wall.

For example, Utility Model Registration No. 2557353
As shown in Japanese Patent No. 2597911, the position regulating rib of the cartridge storage case facing the lid side wall is arranged at a position not including the rotation axis of the lid and the sliding axis of the upper lid. Consider the case. In this case, the position regulating rib of the cartridge storage case facing the lid side wall or the upper lid side wall abuts on the lid side wall or the upper lid side wall, and the load applied at this time deflects the lid side wall or the upper lid side wall in the range of the gap or space. However, there is a problem of causing deformation and destruction. Furthermore, in order to avoid this problem, when taking measures such as increasing the thickness of the lid side wall or the upper lid side wall or providing reinforcing ribs on the lid side wall or the upper lid side wall, the outer shape of the cartridge becomes large. In addition, adverse effects such as a reduction in the storage space for the recording medium inside the cartridge have occurred.

[0011]

When a cartridge having a lid or a cartridge having a lid and an upper lid is stored in the cartridge storage case and the cartridge storage case is subjected to an impact load, such as a drop, the cartridge storage case. There is a problem that the position regulating rib causes deformation or breakage on the lid side wall or the upper lid side wall. In order to solve this problem, the number of ribs attached to the side wall of the cartridge storage case is increased, the thickness of the lid side wall or the upper lid side wall is increased, or a reinforcing rib is provided on the lid side wall or the upper lid side wall. Although countermeasures are conceivable, there are adverse effects such as a complicated structure of the cartridge storage case, an increase in the outer shape of the cartridge, and a reduction in the storage space for the recording medium inside the cartridge.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems in the prior art, and it is an object of the present invention to solve the above problem by applying a load to a lid side wall or an upper lid side wall by a position regulating rib of a cartridge storage case. The purpose of the present invention is to prevent the lid side wall or the upper lid side wall from being deformed or destroyed when.

[0013]

SUMMARY OF THE INVENTION The present invention is directed to a recording medium having a lid having a front surface side of a cartridge body that can be opened and closed with a rotating shaft, and an upper lid slidably provided with a sliding shaft. A storage case for a cartridge, wherein a protrusion protruding to the inside of the left and right side walls of the storage case main body is provided, and the position of the protrusion is set to a rotation axis of a lid of the cartridge when the cartridge is stored in the storage case main body. And / or a position opposite to a sliding axis of the upper lid, wherein the protrusion is provided in the rotation direction in all the storage directions in which the cartridge can be stored in the storage case. A cartridge storage case, which is arranged at a position facing a moving shaft and / or the sliding shaft, and wherein the rib is a position regulating rib. It is paid case.

[0014]

Embodiments of the present invention will be described below. At this time, the form of the cartridge storage case may be a form having a peripheral wall facing the lid side wall, and the detailed structure is not particularly limited. For example,
A form in which the lid is opened and closed by rotating relative to the main body to open and close the cartridge (rotating open / close type), or a part of the peripheral wall of the cartridge storage case has an opening for inserting and removing the cartridge, and the cartridge is inserted.
