Claims

[Scope of utility model registration request]

The cut sheet is sandwiched between a platen and a pinch roller that presses against the platen, and the cut sheet is transferred by rotation of the platen,
In a printer that prints on the ticket using a print head that is provided on a carriage guided by a guide shaft so as to be movable toward the platen, the Vinci roller is mounted on a leaf spring whose base is fixed to a rotatable shaft. A cam follower is attached to the distal end portion and is rotatably provided on the guide shaft to fix the cam and the lever to the guide shaft, and a cam follower is provided which is biased by a biasing means and comes into pressure contact with the cam. The cam is connected to the shaft via a rond, and the shape of the cam and the connecting position of the cam are such that the rotation of the shaft driven by the cam via the rond is determined when the lever is rotated in one direction. The pinch roller moves in the direction of increasing the pressing force against the platen due to the rotation of the cam, and the print head moves so that the gap with the platen becomes larger due to the rotation of the cam, and the lever is rotated in the opposite direction. When the print head is rotated, the vinch roller is brought into pressure contact with the platen with a pressing force corresponding to the amount of rotation, and the print head is set to face the platen with a printing gap corresponding to the amount of rotation. A ticket feeding mechanism characterized by the following.
