Description

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

2. Description of the Related Art Conventionally, a cassette is known that includes a tape and an ink ribbon for printing on the tape. For example, an ink ribbon cartridge disclosed in Patent Document 1 includes a ribbon cartridge and a print sheet cartridge. The ribbon cartridge accommodates an ink ribbon and a take-up shaft for taking up the ink ribbon. A print sheet is contained within the print sheet cartridge. The print sheet cartridge is superimposed over and integrated with the ribbon cartridge. The ribbon cartridge is provided with a head opening into which the head of the printer is inserted. A sheet opening through which the print sheet passes is provided in the print sheet cartridge at a position opposite to the head opening with respect to the roll of the print sheet. After the print sheet is pulled from the roll, it exits the print sheet cartridge through the sheet opening. The print sheet then passes around the perimeter wall of the print sheet cartridge and through the head opening. At the head opening, the print sheet and the ink ribbon are superimposed on each other and printed by the print head of the printer. The ink ribbon used for printing is taken up by a take-up shaft inside the ribbon cartridge.
