A coin acceptor includes main body having coin dispenser mounted therein, coin tubes mounted in the main body and disposed at the bottom side of the coin dispenser, and sensing device including multiple optical sensor modules respectively aimed at the coin tubes. The distance between each optical sensor module and the coins in the respective coin tube is calculated by: measuring the time taken for the reflected light to travel from the coins in the respective coin tube to the proximity sensor of the respective optical sensor module and then multiplying the time thus measured by the speed of light. The number of coins in each coin tube is calculated by: deducting the distance between the respective optical sensor module and the coins in the respective coin tube from the pre-measured depth of the empty coin tube, and then dividing the reminder thus obtained by the thickness of single coin.

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.
