れている。(Example) Hereinafter, an example is described based on a drawing. First, the cassette case comprises a case body (1) and a lid body (5) fitted to cover the upper part of the case body.
Inside, there is a supply spool (12) around the unused ink ribbon (2) wound on the right side, and a used ink ribbon (2) rotated by a recording device to finish printing on the left side. The take-up spools (13) for take-up are respectively arranged, and the running path of the ink ribbon (2) from the supply spool (12) to the take-up spool (13) is configured. That is, the ink ribbon (2) pulled out from the supply spool (12) has two guide posts (14) (3) and one guide roller (15) which are provided upright on the bottom surface of the case body (1). ) And the direction (1) of the case main body (1) is changed and the recess (1
In 6), it is exposed to the outside of the case, comes into contact with the recording head (a) of the recording device, and then returns to the inside of the case body (1) again, and then passes through the guide roller (17) and the guide post (18) to take up spool. (13) has been reached. A guide shoulder (4) for preventing downward movement in the width direction of the ink ribbon (2) is formed on the outer periphery of the lower end of the second guide post (3) on the way from the supply spool (12) to the recess (16). For guiding the upper end of the guide post (3) to prevent the ink ribbon (3) from moving upward in the width direction around the hole (6) provided in the lid (5). A jaw (7) is provided, and the distance between the guide shoulder (4) and the guide jaw (7) is set to be slightly larger than the width of the ink ribbon (2). Also, this guide post (3)
A friction body (8) made of felt is brought into contact with the side surface of the sheet via the ink ribbon (2) by utilizing the spring force of the leaf spring (9). The width of the friction body (8) is somewhat narrower than the width of the ink ribbon (2), and the friction body (8) is in contact with the central portion of the ink ribbon (2) excluding the edge portion in the width direction. The leaf spring (9) having the friction body (8) fixed to the free end is supported at its base end by a cantilevered post (19) provided near the inner surface of the side wall of the case body (1). There is. In the figure, (20) is a rib for pressing the leaf spring (9) substantially in the center of its side surface to slightly deform the leaf spring (9) and urging it. Then, the leaf spring (9) is displaced in the vertical direction on the outer sides of both edges in the width direction of the leaf spring (9), that is, on the top surface of the lid body (5) and the bottom surface of the case body (1). Ribs (10) and (11) that regulate the are projected. The upper and lower ribs (10)
The gap between the leading edge of (11) and the widthwise end of the leaf spring (9) is small, and even if the leaf spring (9) is displaced up and down to the maximum extent, the leaf spring (9) is fixed to the leaf spring (9). The friction body (8) is suppressed so as not to move to the widthwise end edge of the ink ribbon (2).

ンクリボンの正常な走行を安定化できるようになる。(Effects of the Invention) The present invention is as described above, and by providing the guide jaw (7) and the guide shoulder (4) at the upper and lower ends of the guide post (3), the ink ribbon (2) can be formed. The vertical movement in the width direction is suppressed, and the ribs (10) are provided on the top surface of the lid body (5) and the bottom surface of the case body (1), respectively.
By providing (11), the vertical displacement of the leaf spring (9) fixed to the friction body (8) is suppressed, so that the contact position of the friction body (8) with respect to the ink ribbon (2) is suppressed. Is stabilized, and even if dust or ink debris adheres and accumulates on the end portion of the ink ribbon (2) in the width direction, the friction body (8) is not displaced and comes into contact therewith. It is possible to prevent the tension from increasing due to an increase in the ink jet, and to stabilize the normal running of the ink ribbon.
