Abstract
A conveying device in which positional displacement of a sheet may occur due to, for example, backlash of a mechanical system is provided. In the conveying device, when the speed of an encoder is decelerated to a predetermined speed after an edge of a sheet abuts against a roller during conveyance of the sheet, an encoder position is obtained. After the roller stops due to the backlash, an encoder position is obtained again. An amount of conveyance of the sheet to a print start position is corrected on the basis of the two encoder positions that have been obtained.
