Abstract: A valuable paper position correction method for correcting an offset valuable paper includes the step of enabling two sensors of a sensor unit to sense the presence of the valuable paper, the step of determining the time span between the detection of the sensors, the step of calculating the difference in distance between the two bill-transfer roller sets using the detected data of the time span and the revolving speeds of motors, the step of calculating the length of time needed for speed change, the step of controlling one of the motors to change its speed in driving the respective bill-transfer roller set, and the step of controlling the speeded up or slowed down motor to return to its former speed after the length of time for speed change is up.

Abstract: 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.
