ABSTRACT:
A tape cassette capable of permitting a parting line during manufacturing of a die for molding a casing thereof to be kept constant to accomplish joining between an upper casing member and a lower casing member with increased accuracy and facilitate incorporation of components for the cassette into the casing. The upper casing member has tapping bosses for screwing provided thereon and having the same height as a peripheral wall thereof. The lower casing member has tapping bosses, at least one of which also functions as a reference hole, and which have a height greater than a peripheral thereof. The tapping bosses of the lower casing member which are arranged on opposite sides of a front portion of the casing are each formed on a peripheral wall thereof with a cutout so as to fit therein a portion of a front wall of the upper casing member. Alternatively, the front wall of the upper casing member is formed with cutouts in proximity to respective tapping bosses, each of which cutouts is arranged so as to fit therein a portion of a peripheral wall of a corresponding one of the tapping bosses of the lower casing member.
