Recording tape cartridge
First Claim
1. A recording tape cartridge comprising:
- a case rotatably accommodating a single reel on which a recording tape is wound;
a leader tape attached to an end portion of the recording tape, and disposed along a side wall of the case;
an opening for pulling-out of the leader tape, the opening being formed at a corner portion of the case which corner portion extends over respective portions of a front wall and the side wall of the case;
a door, whose a most thin-walled portion has a thickness of 0.6 mm or greater, and which opens and closes the opening by rotating around a supporting shaft provided at a front wall side;
an allowing portion formed in the door so that a deepest surface thereof is formed in a circular-arc shape as seen in plan sectional view, the allowing portion allowing avoidance of contact between the door and a distal end surface of the leader tape when the door closes the opening; and
a guide portion formed at the allowing portion, and abutting a distal end portion of the leader tape, which is further forward than a hole portion engaged by a pullout member of a drive device, and formed to be thick-walled in a direction of making the distal end portion of the leader tape move away from the side wall, wherein, when the door closes the opening, a predetermined clearance is ensured between the distal end surface of the leader tape and the deepest surface of the allowing portion.

Abstract
The present invention provides a recording tape cartridge. The recording tape cartridge includes at least a door opening and closing an opening by rotating around a supporting shaft provided at a front wall side; an allowing portion formed in the door, which allows avoidance of contact between the door and a distal end surface of a leader tape when the door closes the opening; and a guide portion formed at the allowing portion, and abutting the distal end portion of the leader tape, and formed to be thick-walled in a direction of making the distal end portion of the leader tape move away from the side wall. When the door closes the opening of the recording tape cartridge, a predetermined clearance is ensured between the distal end surface of the leader tape and a deepest surface of the allowing portion.
