TAPE CASSETTE |
摘要 |
Disclosed is a tape cassette having a front cover urged in the direction for covering, by pivoting, a tape stretched along the front surface of a cassette case, and a cover-locking piece adapted to pivot within a plane thicknesswise of the tape cassette while being urged in the direction for holding the pivoting of the front cover when it is not in use. The tape cassette is further provided with an optical path aperture formed in a side surface portion thereof in order to form an optical path through the tape stretched inside the tape cassette when it is in use. The tape cassette is improved in its assembling efficiency while preventing disengagement of urging springs thereof in assembly. Moreover, it is possible to obtain satisfactory functions of the front cover and the cover-locking piece while preventing foreign matter such as dust from entering the inside of the tape cassette by covering the optical path aperture when the tape cassette is not in use. Furthermore, the tape cassette can be made microminiature by permitting the required widthwise dimension thereof to be extremely small. |
