Coin collection apparatus

摘要

A coin collection apparatus for use with a coin validity testing device. The apparatus includes an electromagnetically actuated accept flap located downstream of the testing device which accept flap is pivotally supported to rotate about a horizontal axis to direct coins to a reject channel or an accept channel in response to signals delivered by the testing device. The accept flap is biased by a spring to the reject position. The apparatus further includes a first sensor located downstream of the accept flap and a second sensor located downstream of the first sensor and a processor to which the signals of the testing device and the sensors are supplied. The upper portion of the accept flap engages the wall of the coin channel in the reject position cooperates therewith such that a string to which a coin is attached will be retarded or clamped and the processor will calculate the passing time of the coin based on the timing occurrence of the sensor signals of the sensors to generate a warning signal if the passing time exceeds a predetermined value. An optical string detection device is also disclosed.
