Abstract
A bill validator is provided which comprises a rotator with a slit and being rotatably attached to the bill validator, the slit being capable of aligning with a passageway when the rotator is in an initial position; a driving device for rotating the rotator; and a validator control circuit for judging authenticity of the bill by outputs of detective sensors and for controlling the driving device. The validator control circuit produces outputs to operate the driving device and thereby to rotate the rotator so as to wind some pulling string connected to the bill around the rotator after the bill passes the slit of the rotator, and the circuit evaluates the rotation rate of the rotator, and detects the unauthorized pulling string.
