  • Weight-controlled coin-bearing board device for coin-throwing game machine
    Patent number: 7845645
    Abstract: A weight-controlled coin-bearing board device used in a game machine includes a bearing board pivotally supported on a mounting plate inside the game machine for collecting coins/tokens, a counterweight for keeping the bearing board in balance, screw bolts fastened to the rear side of the bearing board to secure the counterweight, and nuts selectively mountable on the screw bolts to adjust the weight of the counterweight. When the total torque caused by the weight of collected coins/tokens surpasses a preset value, the bearing board is forced to tilt, causing collected coins/tokens to fall from the bearing board.
