Abstract
A sheet conveyance apparatus capable of detecting a sheet end portion in a short time period even if sheets are conveyed at a narrow interval and at high speed, thus making it possible to expedite the start timing of a subsequent sheet alignment operation. In accordance with results of detection by lateral registration detection sensors performed when a sheet reaches a lateral registration detection sensor unit, the sensor unit is moved in a width direction for sheet end detection. Based on a moving distance of the sensor unit from a standby position to a position where the sheet end is detected, a shift amount to be shifted the sheet in the width direction, i.e., a lateral registration error, is computed.
