Abstract

A paper feeding device. A braking content determiner determines a content of braking control on a rotating operation such that rotation of a paper feeding motor stops within a time required for stopping from a time point of detection of a sheet by a sheet sensor to a time point of passing of a trailing edge of the sheet through a paper feeding roller, the time required for stopping being determined based on a length of the sheet in a sheet conveying direction, a predetermined speed of the paper feeding roller, and a distance between the paper feeding roller and the sheet sensor in a sheet conveying route. A controller performs the braking control on the rotating operation of the paper feeding motor, according to the content determined by the braking content determiner, upon or prior to the detection by the sheet sensor of the sheet sent out by the paper feeding roller.

Description

technical field [0001] The present invention relates to a paper feeding device for feeding paper. Background technique [0002] Printers such as inkjet printers and stencil printing devices have a paper feeding device that feeds paper from a paper feeding table to a printing unit. In such a paper feeding device, the paper sheets on the paper feeding table are fed out one by one to the intermediate conveying rollers by the paper feeding rollers, and then sent to the registration rollers by the intermediate conveying rollers. The front end of the fed paper comes into contact with the registration roller and stops temporarily. [0003] After the leading edge of the paper stops, the intermediate feed roller continues to feed the paper toward the registration roller side. Thus, slack is formed in the paper between the registration roller and the intermediate conveyance roller during the period before the registration roller starts to rotate. The slack is used to correct the sk...
