Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cartridge carrying case for accommodating and carrying a tape cartridge for a tape recorder or a video tape recorder. More specifically, the tape reel of the accommodated tape cartridge is rotated by vibration during carrying. The present invention relates to a tape cartridge carrying case including a positioning member having a free rotation restricting portion that prevents the magnetic tape from being fed out in the direction.

[0002]

2. Description of the Related Art Generally, a tape cartridge used in a tape recorder or a video tape recorder is made of cardboard or a synthetic resin such as polypropylene or polyethylene, and is a box-shaped tape cartridge storage case with one side open or a tape. A case body in which an outer peripheral wall forming a housing for loading and storing a cartridge is erected, and a lid body that is openable and closable via, for example, a hinge part integrally connected to the case body. It is provided by being stored in a tape cartridge storage case or the like configured by.

Incidentally, commercial tape cartridges have been increased in size in order to improve image quality and enable long-time recording. For example, in a tape cartridge for digital recording and reproduction, a width of 366 mm and a width of 206 m
Also, there is provided one having an external dimension of 33 mm in thickness and a thickness of 33 mm, and its weight is extremely large. Such a tape cartridge storage case for storing a large-sized tape cartridge mainly used for business use is configured similarly to the above-described box-shaped tape cartridge storage case for storing a small-sized tape cartridge. In
In addition to being difficult to carry, there is a problem that protection of the stored tape cartridge cannot be expected against a drop impact or the like.

For this reason, as a tape cartridge housing case for housing a large-sized tape cartridge mainly used for business, a case main body portion in which a tape cartridge loading concave portion for loading the tape cartridge is formed by a hard synthetic resin material. There is provided a carrying case type hard case including a lid body that can be opened and closed via a hinge with respect to the case body.

That is, this tape cartridge carrying case has a case main body portion having a rectangular tape cartridge loading concave portion having an opening dimension substantially equal to the external dimension of the tape cartridge and having the tape cartridge loaded therein. A hinge part that is provided integrally with the open one side part of the case body part by making it thin to provide flexibility, and a side part that is connected to the hinge part and constitutes the open side part. A side wall portion and a lid body portion integrally connected through a thin hinge portion having flexibility and provided with a tape cartridge loading concave portion having an opening dimension substantially equal to the outer dimension of the tape cartridge. ing.

On the bottom surface of the tape cartridge loading recess of the case main body, a pair of positionings are provided in the longitudinal direction in correspondence with the reel hubs of the tape supply reel and the tape take-up reel of the tape cartridge loaded and stored. The convex portion is integrally projected. Therefore, the positioning protrusions are respectively fitted to the reel hubs of the tape supply reel and the tape take-up reel of the tape cartridge housed in the tape cartridge housing recess to position the tape cartridge in the housing direction or in the tape cartridge housing recess. I do.

On the other hand, the tape cartridge is provided with a tape reel lock mechanism for restricting the rotation of the tape reel in the tape feeding direction so that the magnetic tape wound around the tape reel may not loosen. ing. The tape reel lock mechanism includes a ratchet tooth formed on the outer peripheral portion of the tape reel and elastic claws that mesh with the ratchet tooth, and a reel lock member that restricts the tape reel against rotation of the magnetic tape in the feeding direction. It is configured.

[0008]

By the way, although the tape cartridge is provided with the above-mentioned tape reel lock mechanism for preventing the tape supply reel or the tape take-up reel from idling in the tape feeding direction,
When the tape reel is stored in the tape cartridge carrying case and is carried or transported, the tape reel may move in the rotation direction due to vibration and the wound magnetic tape may come off or loosen.

That is, in a tape cartridge, the start end side of the magnetic tape is usually slightly wound around the tape take-up reel, while the magnetic tape is fully wound around the tape supply reel. Therefore, when vibration or the like is applied to the tape cartridge and the tape take-up reel and the tape supply reel move in the rotational direction, the magnetic tape wound around the peripheral surface is not removed from the tape take-up reel or the tape supply reel. Intermittent tensile forces are applied. At this time, a difference in the moment of inertia occurs due to the difference in the amount of the wound magnetic tape between the tape take-up reel and the tape supply reel, and the tensile force of the tape supply reel is far greater than the tensile force of the tape take-up reel. The magnetic tape wound around the tape take-up reel becomes intermittently pulled.

For this reason, in the tape take-up reel, the engagement between the clamper for locking the starting end of the magnetic tape and the engaging portion of the tape reel is not appropriate, or the engaging state of the starting end of the magnetic tape is not sufficient. If it is not good, there is a problem that the start end of the magnetic tape is pulled out from the clamper, or the clamper falls off the tape take-up reel and the magnetic tape comes off.

Further, in the tape supply reel, although the rotation in the tape feeding direction is regulated by the tape reel lock mechanism as described above, the rotation in the tape winding direction is free, so that the tape is intermittently rotated. By the unidirectional movement, the outer peripheral side is pulled by the tape take-up reel and the inner peripheral side is pulled toward the take-up side. Therefore, in the tape supply reel, the winding state of the magnetic tape is not uniform between the outer peripheral portion and the inner peripheral portion, and especially the winding pressure state is loose at the inner peripheral portion, so-called cinching phenomenon occurs and the magnetic tape wrinkles. There was a problem that occurred.

As a measure against the above-mentioned problems, a tape reel idling restricting member is attached to each of a pair of positioning protrusions protruding from the bottom surface of the tape cartridge loading recess of the case body. As shown in FIGS. 8 to 10, the conventional tape reel idling restricting member 100 is formed of an elastic material into a substantially cylindrical shape, and is provided on the outer peripheral portion of the positioning protrusion 101A protruding from the case body 101. It is fitted and attached respectively.

The tape reel idling restricting member 100 is fitted relative to the rotation stop rib portions 102B formed along the inner circumference of the reel hub 102A of the tape supply reel 102 and the tape take-up reel 102, respectively, and frictional force is applied. Prevents idling. Tape reel idling regulation member 100
Has a problem that the frictional force is small because the frictional force with the tape supply reel 102 and the tape take-up reel 102 is obtained only by the elastic force in the thickness direction.

Further, the tape reel idling restricting member 100
Is a tape supply reel 102 and a tape take-up reel 1
Since the fitting tolerance between the reel hub 102A of No. 02 and the diameter dimension of the positioning convex portion 101A is small, there is a problem that the frictional force for preventing idling also varies due to the variation in the molding dimension.

Therefore, according to the present invention, by reliably preventing the tape supply reel and / or the tape take-up reel of the accommodated tape cartridge from moving in the rotational direction, the magnetic tape may be detached or the magnetic tape may be removed when carrying the tape cartridge. An object of the present invention is to provide a tape cartridge carrying case capable of surely preventing occurrence of a phenomenon such as looseness.

[0016]

SUMMARY OF THE INVENTION A tape cartridge carrying case according to the present invention, which achieves this object, positions a tape cartridge loaded by being fitted into reel hubs of a tape supply reel and a tape take-up reel, respectively. In a tape cartridge carrying case having a tape cartridge loading recess provided with a pair of positioning members to be stored, the positioning member includes a base portion projecting from a bottom surface of the tape cartridge loading recess,
Between an annular free-wheeling restricting portion which is concentrically provided on the outer peripheral portion of the base member and elastically deforms and engages with the hub hole of the reel hub, and an outer peripheral portion of the base member and an inner peripheral portion of the free-wheeling restricting portion. It is composed of a diametrically elastically deformable connecting piece.

Further, in the tape cartridge carrying case according to the present invention, when the connecting piece is idled in the winding direction of the tape supply reel and the tape take-up reel, the connecting piece is accompanied by the rotation of the idling restricting portion. Are elastically displaced in the diametrical direction of the base portion, and are respectively inclined and provided in a direction in which the outer peripheral portion of the idling restricting portion is widened.

Further, in the tape cartridge carrying case according to the present invention, a plurality of fixing bosses to which the base portion of the positioning member is attached and fixed are provided on the bottom surface of the tape cartridge loading recess. Alternatively, in the tape cartridge carrying case according to the present invention, a prismatic fixing boss to which the base portion of the positioning member is attached and fixed is erected on the bottom surface of the tape cartridge loading recess.

[0019]

According to the tape cartridge carrying case of the present invention having the above-described structure, the positioning member provided on the bottom surface of the tape cartridge loading recess can be used as a tape supply reel or a tape take-up reel during carrying or transportation. The free rotation restricting portion is rotated as the reel rotates.

In the positioning member, the connection pieces, which are provided to be inclined with respect to the diametrical direction of the base body portion, are elastically deformed in the diametrical direction and are started up in accordance with the rotation of the idling restricting portion, whereby the locating member is free from play. The outer peripheral portion of the rolling restricting portion is expanded and the frictional force is increased.

Therefore, in the positioning member, the outer peripheral portion of the free rotation restricting portion is more firmly and relatively engaged with the hub hole of the reel hub of the tape supply reel or the tape take-up reel, and the tape of the tape supply reel or the tape take-up reel is taped. Since the free rotation in the feeding direction or the tape winding direction is regulated, the detachment of the magnetic tape or the occurrence of the cinching phenomenon is prevented.

Further, in the tape cartridge carrying case, the positioning member is attached to the tape supply reel or the tape take-up reel because a plurality of fixing bosses for fixing the positioning member are erected on the bottom surface of the tape cartridge loading recess. Since the movement is reliably prevented, the free rotation of the tape supply reel or the tape take-up reel in the tape feeding direction or the tape winding direction is more reliably regulated.

Further, in the tape cartridge carrying case, the positioning member serves as a tape supply reel or a tape take-up reel because a prismatic fixing boss for fixing the positioning member is erected on the bottom surface of the tape cartridge loading recess. Since it is surely prevented from being driven, free rotation of the tape supply reel or the tape take-up reel in the tape feeding direction or the tape winding direction is more reliably regulated.
