ンの折れ、しわの原因となる欠点があった。DETAILED DESCRIPTION OF THE INVENTION Conventionally, as a structure of an ink ribbon cassette, as shown in FIG. 1, an ink ribbon pancake is provided inside a cassette body (1).
(2), spool (3), leaf spring (4), winding core (5), spool mounting shaft (6) are built in, and the ink ribbon is between the leaf spring (4) and the boss (7). And passes through the ink ribbon outlet (8) and the ink ribbon inlet (9) and is wound onto the winding core (5). At this time, the inertial force of the ink ribbon pancake (2) itself causes excessive rotation when the running of the ink ribbon is stopped, causing slack. In order to prevent this, a leaf spring (4) is used to apply tension to the ink ribbon. However, this method has a drawback that the control is not complete and the ink ribbon between the leaf spring (4) and the boss (7) moves up and down during traveling, which causes the ink ribbon to break and wrinkle.

止時には、弛みを防止する事が可能である。Hereinafter, a detailed description of this invention will be given. The ink ribbon cassette according to the present invention, like the ink ribbon cassette of FIG. 2, has an ink ribbon pancake (2), a spool (3), a winding core (5), a spool mounting shaft (6) in the cassette body (1). ), A felt, a sponge, or other braking member (10). The braking member (10) is the cassette body (1).
It is provided on the outer circumference of the spool mounting shaft (6), contacts the inner surface of the spool (3), and controls the rotational movement of the ink ribbon pancake (2) with its frictional resistance to stabilize the ink ribbon. It is possible to apply tension to prevent loosening when the running of the ink ribbon is stopped.

なかった。(Example 1) An ink ribbon cassette using a felt member having a thickness of 1.5 mm was printed on the braking member (10) at a printing speed of 30 cps, and the running state and slack of the ink ribbon were observed. At this time, the ink ribbon was not broken and wrinkled, and the ink ribbon was not loosened.
（実施例２） 制動用部材(10)にウレタンスポンジ1.３mm厚を使用した
インクリボンカセットを用い、実施例１と同様のテスト
を行った結果、インクリボンに折れ、しわが発生せず、
インクリボンの弛みも見られなかった。(Example 2) The same test as in Example 1 was conducted using an ink ribbon cassette in which urethane sponge 1.3 mm thick was used as the braking member (10), and as a result, the ink ribbon was not broken or wrinkled.
There was no slack in the ink ribbon.

弛みがあり、走行も不安定であった。(Comparative Example) Next, in the ink ribbon cassette with leaf springs shown in FIG.
The same tests as in Example 1 and Example 2 were performed. At this time, the running of the ink ribbon was unstable because the ink ribbon was loosened when the ink ribbon was stopped and when printing was started.
