Abstract
If the number of returned bills is two or more, the returned bills are identified as abnormally returned bills by an abnormally returned bill detecter, and predetermined abnormal-state processing is accomplished by performing control operations using an abnormality processor. If a bill has jammed in the bill conveying channel, information concerning the direction in which the bill has jammed is stored in the bill jamming direction memory unit of the control unit, and, as a result of control operations performed by the bill reverse-direction conveyance control unit of the control unit, the bill is conveyed in the direction opposite to the bill jamming direction stored in the bill jamming direction memory unit when the bill jammed in the bill conveying channel is to be removed. A shutter that opens and closes the bill conveying channel is also installed and the shutter is driven via a gear transmission comprising a worm gear that develops considerable frictional force between the engaged gears and has a high reduction rate as viewed from the motor side, and a worm wheel that engages the worm gear.
