Abstract
A tape cassette having a lid attached to its front surface portion so as to become openable and closable, the lid being composed of a front lid and a back lid and in which cam bosses provided on respective side portions of the back lid are guided along cam grooves formed on a cassette housing of the tape cassette to thereby open and close the lid when the lid is opened and closed. The tape cassette comprises a retaining member formed on the cassette housing in the vicinity of an upper end portion of the cam groove, wherein when the back lid is opened, the cam boss is brought in contact with the retaining member at the position in which an upper portion of the cam boss is projected from at least a lower surface of the retaining member, thereby preventing the cam boss from being disengaged from the cam groove.
