Claims

[Scope of claim for utility model registration] (1) A printing head, a paper conveying means using a gear train for conveying recording paper to the printing section of the printing head;
The printer includes a drive motor that drives the gear train, a driver that energizes the drive motor, and a control means that controls the driver, wherein the control means controls the gear train after the drive motor rotates in reverse. A printer comprising: a corrected forward rotation signal output means for outputting to the driver a signal for forward rotation of the drive motor by the amount of column backlash. (2) The control means temporarily stores the reverse rotation of the drive motor, and the corrected normal rotation signal output means:
When the print request signal is output, a signal is output to the driver to rotate the drive motor in the forward direction by the amount of backlash of the gear train, in accordance with reverse rotation information of the drive motor stored in the control means. Scope of Claim 1 for Utility Model Registration
Printer mentioned in section.
