Abstract
A separation conveyance device comprises: a separation unit that includes a first roller feeding a conveyance object, and a load unit applying a load to the fed conveyance object, and separates one conveyance object from conveyance objects; a second roller that conveys the fed conveyance object; a driving unit that causes a motor to rotate the first roller at a first linear speed and the second roller at a second linear speed higher than the first linear speed; a connection unit that cuts off the motor's power from the first roller when first load torque toward a rotation direction of the first roller is equal to or larger than a certain value; a detection unit that detects second load torque in the direction opposite to a rotation direction of the motor; and a determination unit that determines a separation state of the conveyance object based on the second load torque.
