On equipment parts 22 and 22 with desired height provided along both the internal sides of a housing, the plastic sheet 20 is mounted and after bosses 23 stood on the housing are inserted into corresponding through holes 24, the sheet is crimped by ultrasonic wave or heat. Other members in the cassette half, e.g., the unnecessary part 25 of a setting piece 15 is cut to form a window. Thus, the extremely simple constitution prevents a tape from coming off axially. |
