Claims

[Scope of utility model registration request]

Cut paper that has a paper feed mechanism that feeds the cut paper one sheet at a time, and registration rollers that correct the skew of the cut paper and feed the cut paper after stopping the leading edge of the cut paper for a certain period of time to prevent misalignment of the printing position. Cut paper conveyance control characterized in that, in a conveyance device, the registration roller drive motor is held while the leading edge of the cut paper is stopped for a certain period of time, thereby preventing rotation of the registration rollers while the cut paper is stopped due to the rigidity of the cut paper. Device.
