Abstract
A coin jam detection system for detecting a coin jammed in a coin runway of vending machines, or other coin operated machines is described. The system includes a coin runway sensor attached to a coin runway, a coin sensor and a microprocessor. A timer in the microprocessor is used to measure the time elapsed between when a coin is sensed by the coin runway sensor and by the coin sensor in the coin mechanism. If the timer exceeds a certain predetermined time limit, a jam condition is assumed and a repair signal may be generated.
