Description

This invention relates to a cassette that is detachably attached to a printing apparatus. Conventionally, cassettes comprising a tape and an ink ribbon for printing on the tape are known. For example, the ink ribbon cartridge described in Patent Document 1 comprises a ribbon cartridge and a printing sheet cartridge. The ribbon cartridge houses the ink ribbon and a winding shaft for winding the ink ribbon. The printing sheet cartridge houses the printing sheet. Multiple set claws are provided on the outer periphery wall of the printing sheet cartridge. By engaging the multiple set claws with the ribbon cartridge, the printing sheet cartridge is superimposed on top of the ribbon cartridge and integrated with it. The ribbon cartridge is provided with a head opening into which the printer head is inserted. On the printing sheet cartridge, opposite the head opening relative to the roll of the printing sheet, is provided a sheet opening through which the printing sheet passes. After the printing sheet is pulled from the roll, it is exited the printing sheet cartridge through the sheet opening. The printing sheet then passes around the outer periphery wall of the printing sheet cartridge and through the head opening. At the head opening, the printing sheet and the ink ribbon are superimposed on each other, and printing is performed by the printer head. The printed sheet is guided to the film gate for ejection by a set claw on the head opening side. The ink ribbon used for printing is wound onto a rewinding shaft.
