Abstract

To provide a thermal printer in which printing is carried out at a constant line interval while employing a DC motor as the power source for feeding a recording sheet.The printer comprises a sheet feed control section 25 including a unit 6 for feeding a recording sheet 3a using a DC motor 8 as a power source, a print head 5 for printing on the recording sheet 3a being fed, and a section 23 for detecting the feeding amount of the recording sheet 3a and controlling the DC motor 8, and a print control section 24 for controlling the print head 5. Feeding amount b of sheet is detected after stopping power supply to the DC motor 8 before feeding of the recording sheet 3a is stopped. Subsequent printing is started after starting power supply to the DC motor 8 and feeding the sheet by an amount (a) determined by subtracting the sheet feeding amount b from a specified interline sheet feed amount c thus performing printing at a constant line interval.

Description

technical field [0001] The present invention relates to a line printer that uses a DC motor as a drive source to feed recording paper. Background technique [0002] As a power source for feeding paper in a printer, various forms such as a stepping motor and a DC motor are known. A DC motor has the advantage of being able to reduce manufacturing costs compared to the case of using a stepping motor. For example, an example is described in which a DC motor is used instead of a stepping motor as a power source for paper feeding in a thermal printer having a thermal print head. (Japanese Patent Application Laid-Open No. 11-291535) [0003] However, this DC motor does not have a rapid rise characteristic at the start of driving, or a rapid stop characteristic at the stop of driving, compared with a stepping motor. Therefore, when a DC motor is used as the power source for feeding the recording paper, in order to end the printing of the recording paper and stop the feeding of th...
