Abstract: A coin denomination discriminating device for improving coin dispensing devices which incorporates components formed of non-magnetic material including a non-magnetic rotor having a coin receiving portion and a non-magnetic reference guide to guide coins from a storage coin holding bowl to a coin conveying device capable of selectively releasing coins of various denominations. Magnetic sensor units can be positioned along the coin movement path to provide characteristic signals representative of the coins independent of influence of metallic components in the transporting path. The non-magnetic members can be formed from wear resistant plastic material and relatively inexpensive magnetic sensors with coil and ferrite coils can be utilized adjacent the rotor.

Abstract: The first purpose is to provide a coin selector which can be easily set up the standard data without putting coins into the coin selector. The second purpose of this invention is to provide both a coin selector and a outside setting unit which are not easily changed in the standard data. A coin selector comprises of; plural standard data memory for memorizing standard data, a selecting means which can be effective a selected standard data memory based on a direction from an outside setting unit, a distinguishing means which compares the memorized data of said selected standard data memory and the outputting data of a coin sensor and outputs an authenticity signal, a gate controlling means which controls a gate based on an output from the distinguishing means.

Abstract: A coin selector is provided which is adapted to electronically sample coins and compare the sampling data to stored data for genuine coins. The stored data can be preset or can be acquired and stored in memory by using a key coin. Data stored determines if a key coin is authentic and if it is, places the selector processor in a condition to accept and store new or modified data for determining the authenticity of other coins.
