Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
297 words
A magnetic recording tape cartridge comprising: a) a bottom section and a top section assembled together by a fastening means so as to provide a cartridge case having a front wall and a tape chamber with a plurality of openings formed in said front wall, b) at least one reel accommodated in said tape chamber, rotatably mounted relative to a drive shaft insertion hole defined in a bottom plate of said bottom section of the cartridge case, c) a magnetic recording tape wound around said reel, the intermediate portion of said recording tape being stretched running along a predetermined path defined by said front wall, d) a lid member hingedly mounted on the cartridge case and having a generally straight lid plate disposed generally parallely with the front wall to close said openings of the front wall to protect the magnetic recording tape situated along the front wall, said lid member being rotated in a direction away from said front wall when used, e) an engaging member projecting from said lid member to the interior of the cartridge case through an opening defined in the front portion of the cartridge case, f) lock means having a locking member and rotatably mounted in the interior of the cartridge case with the locking member detouchably engaging with the engaging member of the lid member to lock the lid member in a closed position and said lock means being operated to release the engagement of the locking member from the engaging member of the lid member to allow the lid member to move to an opened position, and g) a through-hole defined to oppose a part of the locking means in the bottom face of the bottom section to allow passage of a lock releasing pin of a recording/reproducing apparatus.
