[Scope of Claim for Utility Model Registration] (1) A conveyor rotating body that feeds the sheet to a predetermined position and then stops, a motor that can rotate forward and backward to drive the conveyor rotary body, and a motor that detects the direction of rotation of this motor. and a reverse rotation detection means, which receives a stop instruction signal for the motor to forward or reverse the direction of the current supplied to the motor, and receives a rotation direction detection signal from the forward and reverse rotation detection means and controls the supply of current to the motor. A sheet conveying device comprising a drive control means for shutting off the drive. (2) The forward/reverse detection means detects a rotating body rotationally driven by the motor, a plurality of detected objects provided at predetermined intervals in the rotational direction of the rotating body, and temporally detects the detected objects. The motor is characterized by comprising a plurality of sensors that detect at different timings, and a circuit that determines the rotation direction of the motor based on a difference in the order of signals output from the sensors when the motor rotates forward and when it rotates reversely. A sheet conveying device according to claim 1 of the utility model registration claim.
