Claims

[Scope of claim for utility model registration] Forming a conveyance path for conveying paper in the frame,
A printing unit is provided with a platen at the end of the conveyance path, and is pivotally supported on the upper part of the frame so as to be able to rotate upward, and opens the conveyance path and the platen upward when rotated upward. In a printer equipped with a printer, a drive roller driven by power transmission from a motor is provided in the middle of the conveyance path, and a driven roller that pinches and conveys the paper by rolling in contact with the drive roller so as to be able to come into contact with and separate from the drive roller. The left and right rotating arms that rotatably support the driven roller are rotatably supported on the frame via a support shaft, and the rotating arms are supported by a spring in the direction in which the driven roller comes into contact with the driving roller. A printer characterized in that the rotating arm is provided with an operating lever that is guided above the frame and rotates the driven roller in a direction away from the driving roller.
