| 主权项 | 1. A sheet conveying apparatus comprising: a first sheet conveying unit to convey a sheet by a driving force of an asynchronous motor; a second sheet conveying unit to convey a sheet by a driving force of a synchronous motor, wherein a sheet is transferred from one of the first sheet conveying unit and the second sheet conveying unit to the other one to convey the sheet; and an asynchronous-motor control unit to start drive of the asynchronous motor at a drive start timing determined according to a sheet conveyance speed and according to rotation information at a time of acceleration of the synchronous motor, at a time of starting sheet conveyance when a same sheet is conveyed by both the first sheet conveying unit and the second sheet conveying unit, the asynchronous-motor control unit being further configured to acquire the sheet conveyance speed from a drive control unit configured to control drive of a third sheet conveying unit configured to convey a sheet on an upstream side in a sheet conveyance direction of the first sheet conveying unit and the second sheet conveying unit. | ||
