    摘要: When a bill is inserted into the bill acceptor, sensor components sense the insertion of bill, bill-pressing roller set of bill transmission mechanism is driven to press bill, bill-transfer roller set is driven to transfer bill the bill-pressing roller set is released from the bill, and step motors of alignment correction unit are controlled to move correction devices toward each other to align the bill with the center line of bill passage subject to a predetermined number of steps. If the resistance force from bill is larger than the thrust force produced during rotation of step motors, utilize the step loss status of step motors and enable transmission devices to move correction devices away from bill when the rotation of step motors reaches the predetermined number of steps, and then enable bill-pressing roller set to press bill again and then enable bill-transfer roller set to transfer bill.
