した。Means for Solving the Invention In order to achieve the above object, the present invention provides an ink ribbon cassette comprising a case body having a driving roller for driving the ink ribbon and a driven roller, and a lid protruding a cam. Attached to the case body so that the driven roller swings in the direction of the drive roller with the driven roller, and the holder is provided with an arm whose tip end swings in a direction substantially orthogonal to the swinging direction of the holder. When the lid is removed, the tip of the arm is locked to the locking portion provided on the case body to separate the driven roller from the drive roller, and when the lid is covered, the tip of the arm is swung by the cam in the swinging direction of the holder. And the holder including the arm tip is swung in the direction of the drive roller, and the driven roller is pressed against the drive roller with the ink ribbon sandwiched, The arm tip is located on the drive roller side of the cam.

い。Operation With this configuration of the present invention, when replacing the ribbon, the cover is removed and the protrusion at the tip of the arm is locked to the locking portion, so that the driven roller is separated from the driving roller and the gap is formed. Easy to insert ribbon. Further, at the time of printing, the projection is detached from the locking portion with a cam by covering the lid, whereby the driven roller that has been separated is automatically repelled by the drive roller, and the ink ribbon is caused to travel. At this time, since the cam locks the projection from the outside, the projection does not move to the locking portion even if an erroneous operation is performed.
