Coin processing apparatus

In a coin processing apparatus wherein the quality and dimensions of a coin that is inserted through an insertion slot are electromagnetically tested by a testing portion as said inserted coin passes along a predetermined pathway, said inserted coin is sent along either a genuine-coin pathway or a counterfeit-coin pathway by the operation of a first pathway switching mechanism in accordance with the results of said testing and an acceptance enabling/disabling decision, then said coin is sent along either a cash-box pathway or a change tube pathway by the operation of a second pathway switching mechanism in accordance with a coin type obtained from the results of said testing, wherein said change tube pathway is divided into separate tube pathways for each coin type, a coin processing apparatus characterized in being provided with:

• a first pass sensor which is provided in said genuine-coin pathway between said first pathway switching mechanism and said second pathway switching mechanism, and which detects the passing of said inserted coin;
• and
• a second pass sensor which is provided in said change tube pathway in the vicinity of said second pathway switching mechanism, and which detects the passage of said coin through said change tube pathway to generate a detection signal;
• wherein the operation by said second pathway switching mechanism of sending said inserted coin into said change tube pathway is halted until the detection signal falls.
