Abstract
A recording tape cartridge disclosed with an increased strength leads to a compact drive device. A rectangular case of the recording tape cartridge accommodates a single reel on which a recording tape is wound. An opening for pulling out a leader member attached to an end of the recording tape is formed in a corner disposed closest to the drive device among corners of the case at the time of insertion into the drive device. The recording tape cartridge includes a shield slidable to open and close the opening, a guide wall for guiding the shield, and a friction-reducing device protruding from the shield. The guide wall is provided along an inner surface of the case. The friction-reducing device abuts the guide surface of the guide wall in order to reduce friction between the shield and the guide surface.
Claims38
A recording tape cartridge comprising:
- a substantially rectangular accommodating case for rotatably accommodating a single reel on which a recording tape is wound, the accommodating case having an opening which is formed by cutting off a corner portion of the accommodating case on a side thereof that is inserted into a drive device, and which is used to pull out a leader member attached to an end portion of the recording tape;
- a shielding member that slidably moves to open and close the opening;
- a guide wall portion which is provided parallel to an inner surface of the accommodating case and which guides the movement of the shielding member;
- and
- a friction-reducing device which is provided so as to protrude from the shielding member, which abuts a guide surface of the guide wall portion, and which reduces friction between the shielding member and the guide surface.
A recording tape cartridge comprising:
- a rectangular accommodating case for rotatably accommodating a single reel on which a recording tape is wound, the accommodating case having an opening which is formed by cutting off a corner portion of the accommodating case on a side thereof in a direction in which the accommodating case is inserted into a drive device, and which is used to pull out a leader member attached to an end portion of the recording tape;
- a shielding member that slidably moves to open and close the opening;
- and
- a guide wall portion which is provided parallel to an inner surface of the accommodating case and which guides the movement of the shielding member,
- wherein a portion of the shielding member other than an opening-blocking portion thereof is formed lower in height than the opening-blocking portion.
