I have a japanese slot machine, no schematics, don't read (or speak) japanese, and no specs or part number.
I've been restoring this machine and converting it to quarters for a few weeks, but has never seem to count payouts, just empties the hopper and gives an error code. At first I thought it was not enough coins, but it does the same when I try to cash out even one credit.
The coins are pushed against a springload post, which moves an arm between the U shaped opto interupter. This portion is working fine, so the counting problem must be the sensor, since the computer gives an error after spitting out 20 or so coins (timer I'd guess).
Schematics for these machines must be rare, have found one for any slot machine. Only found one site sellin this particular machine for $299. So, I'm on my own, and only a basic understanding of this part.
The opto is soldered to a small PCB with a single resistor and a 3 pin connector. The voltage isn't know, but figure 5 volts, its just an IRLED and Photodiode, right? Guessing the LED is the half running through the resistor.
I would like to test the detector and emitter without too much risk of damage, as it might be tough to replace. So far my repairs and modifications have been transparent, and hope to keep it clean. This thing is almost complete. Just this hopper problem and one button needs replaced on the front.
