  • Method and apparatus for detecting fraud or theft in a gaming machine
    Patent number: 5531309
    Abstract: A gaming machine has internal coin container sensors (110, 112) that sense the weight, and therefore, the number of coins contained in the internal coin containers (104, 106). The gaming machine also has mechanical and/or optical sensors (102, 114) to monitor the inflow and outflow of coins. By comparing the number of coins, as determined by weight, with the number of coins detected by the mechanical and/or optical sensors, fraud is readily detected.
