Abstract

A sheet transporting apparatus is provided, including a transport mechanism provided with a roller, a motor, a controller, and a measuring input unit, wherein a transport route has a curved area for inverting the sheet, and the controller is constructed such that the control on the motor is executed by a closed loop control system by using a measured value of an control output at an initial stage of the transport of a sheet from a tray, and the control on the motor is switched from the control performed by the closed loop control system to control performed by an open loop control system on condition that a preset phenomenon arises after the sheet is taken out of the tray.
