摘要： A magnetic tape cassette capable of effectively eliminating a variation in pressure of the elastic pad element during traveling of a magnetic tape and preventing a variation in tension of the tape, to thereby ensure stable and safe traveling of a magnetic tape. The magnetic tape cassette is so constructed that an elastic pad element which is formed into a dogleg shape is supported at the bent portion thereof on a support rod arranged in a casing and a first section of the elastic pad element extending between the support rod and one end of the pad element is arranged so as to extend substantially in the tangential direction of a tape guide roller at the position of the guide roller at which a holding portion of the elastic pad element acts on the guide roller. The first section may be arranged in proximity to the portion of the magnetic tape between the one reel and the guide roller when the holding portion is defined in such a manner as in a conventional magnetic tape cassette typically constructed.

摘要： A magnetic tape cassette capable of positively and rapidly accomplishing the lock release operation irrespective of the direction of force applied to a lock release mechanism to open a front lid. The cassette includes a lock lever regulating mechanism for regulating movement of a lock lever to permit it to be pivotally moved in a direction perpendicular to the longitudinal direction thereof about a holding section of a projection of the lever. The holding section is formed at a position downward apart from the projection and vertically opposite to a lock pawl engaged with the front lid with the projection being interposed therebetween. The lock lever regulating mechanism is constituted by a combination of a position regulating rib provided at the casing and a guide groove formed at the lock lever.
