Claims

[Claims for Utility Model Registration] 1. A pair of left and right ribbon cores 2, 2 are rotatably provided in the cartridge case 1, and both the ribbon cores 2, The ink ribbon cartridge is configured such that both ribbon cores 2, 2 can be engaged with the drive shaft DS of the recording device P so that the ribbon cores 2, 2 are exchanged on the winding side and the feeding side, Frictional resistors 3 that apply running resistance to the ink ribbon R on both left and right sides of a location corresponding to the print head arrangement in the cartridge case 1;
An adjusting tool 4 for adjusting the frictional force of the frictional resistor 3 is provided, and each of the adjusting tools 4, 4 is
The ink ribbon R is linked to the ink ribbon R so that as the tension of the ink ribbon R between the ribbon core 2 and the frictional resistor 3 on the side where they are provided increases, the frictional force exerted by the frictional resistor 3 is weakened. Ink ribbon cartridge. 2. The frictional resistor 3 is a plate spring and is configured to sandwich the ink ribbon R between its free end and the cartridge case 1, and the adjustment tool 4 is a plate spring. One end is in contact with the intermediate portion between the free end of the leaf spring 3 and the fulcrum, and the other end is located between the intermediate portion of the leaf spring 3 and the ribbon core 2 on the side where the leaf spring 3 is provided. The ink ribbon cartridge according to claim 1, which is a lever body engaged with the ink ribbon R. 3. The lever body 4 is a coil spring, and uses its coil portion as a swinging fulcrum, and extends one end of the coil portion to come into contact with the leaf spring 3, and extends the other end of the coil portion into contact with the leaf spring 3. An ink ribbon cartridge according to claim 2, which is extended and engaged with the ink ribbon R. 4. The lever body 4 is a rod-shaped body having a swinging fulcrum in its longitudinally intermediate portion, and has one end thereof brought into contact with the leaf spring 3, and the other end thereof engaged with the ink ribbon R. An ink ribbon cartridge according to claim 2 of the utility model registration claim. 5 The position of the swinging fulcrum on the lever body 4 is such that only the tension applied to the ink ribbon R by the other leaf spring 3 substantially reduces the frictional resistance of the leaf spring 3 in contact with the lever body 4. The ink ribbon cartridge according to claim 2, which is arranged in a position where the ink ribbon cartridge is removed.
