A tape cartridge housing a tape for recording information signals has a cover plate and a pull-in inlet portion. The cover plate is rotatably supported by an opening/closure mechanism and rotated in association with movement of the opening/closure mechanism. The opening/closure mechanism, in turn, is rotatably supported by a main cartridge portion having on its front side a recess into which is intruded a tape pull-out mechanism adapted to pull out the tape. The opening/closure mechanism is adapted to open or close the recess, and the free end of the cover plate has an engagement protrusion. When the engagement protrusion is disengaged from a rotation guide groove provided on the main cartridge portion, the engagement protrusion is pull-in guided by the pull-in inlet portion into engagement with the rotation guide groove.
