(Prior Art and Problems) Conventionally, as a structure of an ink ribbon cassette, as shown in FIG. 1, an ink ribbon pancake (2), a supply side leaf spring (3), and a side leaf spring (4) to be wound up in a cassette body (1). ) And a take-up core (5). The ink ribbon passes between the supply-side leaf spring (3) and the supply-side boss (6), and passes through the ink ribbon outlet (8) and the ink ribbon inlet (9). It is guided between the side leaf spring (4) to be wound up and the boss (7) to be wound up, and is wound up by the winding core (5). At this time, the ink ribbon pancake (2)
To prevent the ink ribbon from becoming loose due to over rotation of
The tension is applied to the ink ribbon using the supply side leaf spring (3). Furthermore, in order to prevent an increase in the winding diameter of the ink ribbon wound around the winding core (5), separate leaf springs are used, such as applying tension to the ink ribbon by using a side leaf spring (5) to be wound. Each was controlled by. However, with this mechanism, the pull-out force of the ink ribbon increases due to the decrease in the diameter of the ink ribbon pancake (2), and it is impossible to apply a constant feeding tension from the start to the end of use of the ink ribbon. Since the ink ribbon pancake (2) itself has no braking force applied thereto, the ink ribbon pancake (2) itself is over-rotated when the ink ribbon travel is stopped by the inertia force of the ink ribbon pancake (2) itself. There was a disadvantage that the ink ribbon became loose between the pancakes (2).

(Object of the Invention) The present invention provides a very simple mechanism for applying a constant tension to the running ink ribbon all the time in order to solve the above-mentioned drawbacks, and at the same time, preventing the occurrence of the slack of the ink ribbon when the ink ribbon travel stops. It is intended to be added with a simple structure.

Hereinafter, the present invention will be described in detail using embodiments of the present invention. The ink ribbon cassette according to the present invention is the second type.
Cassette body (1) like the ink ribbon cassette shown
The bend used to simultaneously contact the ink ribbon pancake (2) and the winding core (5), and the ink ribbon pancake (2) and the ink ribbon pancake wound on the winding core (3). It has a built-in unprocessed elastic thin plate for braking (10). Since the unbended elastic thin plate for braking (10) is rich in flexibility, the diameter of the ink ribbon pancake (2) and the diameter of the ink ribbon pancake wound on the winding core change. Therefore, the ink ribbon pancake (2) and the ink ribbon pancake wound on the winding core can be simultaneously and simultaneously contacted, and a stable tension can be applied to the ink ribbon.

(Example 1) For an elastic thin plate (10) for braking that has not been bent
After printing a fixed distance at a printing speed of 30 cps using SUS304, 0.06 mm thickness, measure the supply side tension and the winding side tension of the ink ribbon, repeat this until the end of the ink ribbon, and change and rewind the tension on the ink ribbon I saw the state.

At this time, the winding state of the ink ribbon in the ink ribbon cassette used in Example 1 and Example 2 was small in vertical movement, and the winding hardness and the winding diameter were constant. The wound ink ribbon in the ink ribbon cassette of the comparative example slightly moved up and down, the hardness of the wound was slightly different inside and outside the wound ink ribbon pancake, and the winding state was unstable.
