Tape cassette

摘要

Includes a case body with a recessed part formed on the side of a lower surface of the case body. A slider in the case body can be slid for opening and closing the recessed portion. A lock member positioned at an opening of the lower case locks the slider in respective positions where the recessed portion is closed or opened. A spring supported at its two side ends with the opening is interposed between by an inner surface of the lower case, for biasing the slider to a lock position. An independent claim is included for a method of manufacturing the cassette.
