Description

cassette

The present invention relates to a cassette that is detachably attached to a printing machine.

Conventionally, a cassette equipped with a tape and an ink ribbon for printing on the tape is known. For example, the ink ribbon cartridge described in Patent Document 1 includes a ribbon cartridge and a printing tape cartridge. The ink ribbon and a winding shaft for winding the ink ribbon are housed in the ribbon cartridge. The printing tape is housed in the printing tape cartridge. The printing tape cartridge is superposed on top of the ribbon cartridge and integrated with the ribbon cartridge. The ribbon cartridge is provided with a head opening into which the printer head is inserted. A sheet opening through which the printing tape passes is provided at a position of the printing tape cartridge opposite to the head opening with respect to the roll of the printing tape. The printing tape is pulled out of the roll and then taken out of the printing tape cartridge through the sheet opening. The print tape then passes around the outer wall of the print tape cartridge and through the head opening. At the head opening, the printing tape and the ink ribbon are superposed on each other, and printing is performed by the head of the printer. The printed printing tape is guided to the film gate for ejecting the printing tape by the set claw on the head opening side. The ink ribbon used for printing is wound by a winding shaft.
