The traditional ribbon cassette usually includes a shell and an internal ribbon roll. The ribbon roll needs to be replaced regularly due to wear and tear, color exhaustion, etc. However, the existing ribbon cassette design often has certain difficulties when replacing the ribbon roll. The user needs to open the ribbon cassette laboriously and go through complicated steps to take out the old ribbon roll and then install the new ribbon roll.

[0003] For example, the patent (CN209441045U) discloses a ribbon cassette assembly, in which a bracket is used to position and support the housing. When replacing the ribbon, the housing is directly taken out from the bracket and replaced with a new housing with the ribbon. The replacement and installation of the ribbon is convenient and fast, and the positioning is accurate, which can reduce the maintenance time of the device.

The ribbon shaft 6 and the transverse connecting tube 7 are slidably connected by the transverse slider and the transverse slide groove. The transverse slider and the transverse slide groove are arranged so that the transverse connecting tube 7 can move transversely inside the ribbon shaft 6, so that the transverse connecting tube 7 can move inside the ribbon shaft 6;

[0031] A vertical limit block is fixed to the bottom of the ribbon top cover 3, and a vertical limit slot adapted to the vertical limit block is provided inside the ribbon bottom frame 1. The ribbon top cover 3 and the ribbon bottom frame 1 are slidably connected through the cooperation of the vertical limit block and the vertical limit slot, so that the ribbon top cover 3 can be installed to the top of the ribbon bottom frame 1;

[0032] An arc-shaped limit block is fixed on one side of the ribbon top cover 3 close to the side movable plate 2, and an arc-shaped limit groove adapted to the arc-shaped limit block is provided inside the side movable plate 2. The ribbon top cover 3 and the side movable plate 2 are slidably connected through the arc-shaped limit block and the arc-shaped limit groove. Through the arrangement of the arc-shaped limit block and the arc-shaped limit groove, the side movable plate 2 can slide on one side of the ribbon top cover 3, thereby releasing the restriction of the side movable plate 2 on the ribbon top cover 3, so that the ribbon top cover 3 can be disassembled;

[0033] The moving mechanism includes an arc-shaped fixed block 8, arc-shaped fixed blocks 8 are fixed at both ends of the bottom of the ribbon bottom frame 1, transverse light rods 9 are fixed on both sides of the arc-shaped fixed block 8, and a transverse sliding tube 10 is slidably connected to the outer side of the transverse light rod 9. A vertical connecting plate 12 is fixed to the side of the transverse sliding tube 10 away from the transverse light rod 9, and the top of the vertical connecting plate 12 is fixedly connected to the side moving plate 2.
