Recording tape cartridge
View Patent ↗The present invention provides a recording tape cartridge comprising: a rectangular case having, at a corner portion, an opening for pulling-out of one end of a recording tape, and accommodating the recording tape; and a cover member which opens and closes the opening. The opening is formed by cutting-off the corner portion of the rectangular case, and when the cover member at least opens the opening, the cover member is accommodated within the case.
1. A recording tape cartridge comprising:
a case for housing a reel of a recording tape and having, at a corner portion, an opening for pulling-out one end of the recording tape;
a cover member which opens and closes the opening; and
an urging member urging the cover member in a direction in which the opening is closed,
wherein the urging member is a torsion spring, and
wherein the cover member is accommodated within the case when the opening is open,
wherein the opening has a plane of opening that is inclined with respect to an insertion direction of loading the recording tape cartridge into a drive device, and the plane of opening extends from a front side of the recording tape cartridge to the right side of the recording tape cartridge, wherein the front side is defined as the front of the recording tape cartridge in the insertion direction and the right side is orthogonal to the insertion direction.
2. A recording tape cartridge according to claim 1 , wherein the case includes a first guide groove and a second guide groove for guiding the cover member to open and close the opening, and wherein the second guide groove is inclined with respect to the insertion direction.
3. A recording tape cartridge comprising:
a case for housing a reel of a recording tape and having, at a corner portion, an opening for pulling-out one end of the recording tape;
a cover member which opens and closes the opening; and
an urging member urging the cover member in a direction in which the opening is closed,
wherein the urging member is a torsion spring, and
wherein one end of the torsion spring passes through the cover member, and an arc-shaped groove is formed in a side wall of the case, and when the cover member opens the opening, the one end of the torsion spring passes through the arc-shaped groove.
