Abstract:
1. A coin denomination discriminating device which is formed of a non-magnetic material and which acquires acquire data for discriminating while conveying coins one by one to a predetermined position, the denomination discriminating device comprising: a non-magnetic slide base slanting at an angle; a coin movement path which is positioned on the non-magnetic slide base; a non-magnetic rotor having a coin receiving portion and is located on the non-magnetic slide base; a magnetic sensor unit including a thickness sensor, a material sensor, a first diameter sensor, a second diameter sensor and a third diameter sensor, wherein a first portion of each sensor is disposed on a first side of the coin movement path and a second portion of each sensor is disposed adjacent to the first portion of each sensor on a second side of the coin movement path to define a sensing pathway therebetween; and a non-magnetic reference guide for guiding a coin, the reference guide being disposed at an outer circumference of the coin movement path, wherein the non-magnetic reference guide has a linear guide part to engage each coin facing the magnetic sensor as the coin is guided linearly through the sensing pathway by the non-magnetic reference guide wherein the thickness sensor is disposed on a first straight reference line which is defined orthogonal to the non-magnetic reference guide, wherein the second diameter sensor is disposed on the first straight reference line in a position outboard of the thickness sensor in relation to the linear guide part, and wherein the material sensor is disposed on a second straight reference line, in a position which is downstream from the first straight reference line, which is substantially orthogonal to the non-magnetic reference guide, the first diameter sensor and the third diameter sensor are disposed on a third straight reference line in positions downstream from the second straight reference line, the third straight reference line is substantially orthogonal to the non-magnetic reference guide.
