Claim Text:
1. A sheet conveyance device, comprising: a motor; an ON-OFF control unit that selectively executes an ON control and an OFF control, the ON control causing the motor to rotate when electric power is supplied to the motor, the OFF control causing the motor not to rotate even when electric power is supplied to the motor; a rotation control unit that selectively executes a first-direction control and a second direction control, the first-direction control setting a rotation direction of the motor as a first direction when the motor is rotated by the ON control, the second direction control setting the rotation direction of the motor as a second direction opposite to the first direction when the motor is rotated by the ON control; a conveyance path for a sheet; a roller that is driven by the rotation of the motor when the motor rotates in the first direction, to rotate in a third direction so as to convey the sheet along the conveyance path; a jam detecting unit that detects a jam of the sheet conveyed along the conveyance path; a cover that is opened at a time of access to the conveyance path, to release the jam; and an interlock switch that is turned off in a state where the cover is opened, so as to cut off a supply of electric power from a power supply to the motor; wherein a rotation direction of the roller when the jammed sheet is pulled out from the roller is preliminarily determined as the third direction among the third direction and a fourth direction, the fourth direction being opposite to the third direction, and the sheet conveyance device further includes a setting unit that sets the ON-OFF control unit to perform the ON control and sets the rotation control unit to perform the second direction control if the jam is detected by the jam detecting unit and the interlock switch has been turned off.
