Abstract
A recording tape cartridge in which a leader block is prevented from flying out from an opening portion of a case when the cartridge is dropped. In the cartridge, a door which opens and closes the opening portion, through which the recording tape passes, is provided. A leader block, which is attached to a distal end of the recording tape, can be accommodated within the cartridge. The door is always resiliently urged in a closing direction. A groove portion is provided at the leader block. A concave rail, which movably fits together with the groove portion, is provided at the door. The leader block and the door contact one another.

A recording tape cartridge comprising:
- a recording tape wound on a reel which is accommodated within a case so as to be freely rotatable;
- a leader block provided at a distal end portion of the recording tape;
- an opening portion formed in the case such that the leader block can pass through the opening portion, and allowing access to the leader block;
- and
- a cover slidably mounted to the recording tape cartridge, so as to open and close the opening portion, and being urged in a closing direction, and configured to come into contact with an opening portion side of the leader block,
- wherein the leader block has a groove portion, and the cover has a rail which corresponds to the groove portion and which extends along a sliding direction of the cover, and, when the cover is closed, the groove portion fits together with the rail such that a clearance is formed between the groove portion and the rail.
