Claims

[Claims for Utility Model Registration] 1. A drive roll 4 is provided on the entrance side of the ribbon storage section 3 that stores the main part of the ink ribbon R in a folded state, and the drive roll 4 engages with the drive roll 4 to sandwich the ink ribbon R. This is a ribbon drive structure of an ink ribbon cartridge in which a driven roll 5 that is pulled into the ribbon storage section 3 side is disposed facing each other when the driven roll 5 is in a state where the driven roll 5 moves in the opposite direction. In addition to providing flexibility to allow movement within a certain range of directions, when the driven roll 5 moves upward in the ink ribbon running direction due to reversal of the driving roll 4, a braking force is applied to the driven roll 5. A ribbon drive structure of an ink ribbon cartridge provided with a reverse rotation prevention means A. 2. The reversal prevention means A has an engaging portion 15 provided on the driven roll 5, and an engaged portion provided on the body case 1 side of the ink ribbon cartridge that can be freely engaged with and detached from the engaging portion 15 from the ribbon running direction. 2. The ribbon drive structure for an ink ribbon cartridge according to claim 1, further comprising a joint portion 14. 3. The reversal prevention means A is comprised of an elastic material 18 provided on the main body case 1 side of the ink ribbon cartridge in order to provide rotational resistance by slidingly contacting the outer peripheral surface of the rotating shaft 5A of the driven roll 5. A ribbon drive structure for an ink ribbon cartridge according to claim 1. 4. Claim 1, wherein the driven roll 5 is urged to move toward the driving roll 4 by a spring 13.
A ribbon drive structure of the described ink ribbon cartridge.
