So this Tuesday we got a whole set of pieces for those claw machines, joysticks, controllers, motors, claw, sidings, the whole set. It’ll keep us busy for a while and was a bit too much for one night, so we focused on what was most interesting to us.
So I, of course, headed straight for the money.
This is a familiar sight to any of you who grew up near a Chuck E Cheese.
This is a timed ramp and deflector to sort out coins. It’s set to accept only quarters.
The coins pass through a width detector (a space with a spring loaded arm pressing against them) if they’re too thick they slow down, and then hit this wheel, which spins to let them past. Heavier coins spin the wheel faster and drop more directly downward.
Lesser coins aren’t deflected enough towards the rear and hit that little brass divider and fall forward to the reject tray. you can see it’s got adjusters, so it was probably manually tested after being assembled.
If the coin gets this far, it hits a fine wire as it rolls through the final ramp, activating this switch and telling the machine we just got a quarter.
