ABSTRACT:
A coin discriminating and counting apparatus including a light emitter disposed linewise in the direction perpendicular to a coin transporting direction on one side of a coin passage with respect to the vertical direction, a sensor array disposed so as to be opposite to the light emitter on the other side of the coin passage, a magnetic sensor for detecting magnetic properties of coins, the magnetic sensor being disposed so that the coin passage and the sensor array are disposed therebetween with respect to the vertical direction, an optical data memory for storing optical data detected by the sensor array, a magnetic data memory for storing magnetic data detected by the magnetic sensor, a coin diameter detector for detecting diameters of coins based upon the optical data stored in the optical data memory, a denomination discriminator for discriminating coin denominations based upon the coin diameters detected by the coin diameter discriminator, a reference magnetic data memory for storing reference magnetic data for respective denominations, a discriminator for discriminating the denominations, currency and the like of the coins by comparing the magnetic data detected when the center portion of the coin passes the magnetic sensor and output from the magnetic data memory with the reference magnetic data output from the reference magnetic data memory, and a counter for counting the value and/or number of coins based upon the results of discrimination in the denomination discriminator and the discriminator.
