摘要

A first sensor (5) fits after a coin input (3). A second sensor (7) fits after a coin output in a coin-checking device (4). Signals from the sensors are fed to a control device (6) for monitoring the passage of coins through the coin-checking device. Exceeding a preset passage time triggers a signal from the control device to return the coins.
