Decade counter with units wheel and tens wheel - has transfer wheel with two separate parts and relay contact control switches

摘要

One part of the transfer wheel is connected to the units wheel and the other engages with the tens wheel. When the decade counter is used for credit storage in coin-operated gaming machines, the units wheel or the tens wheel has assigned to it a quick break switch which switches on a motor with holding contact. This triggers pulses to step up the units or tens wheels by a number of steps corresp. to the value of the coin by means of a cam disc driven from the motor. The contact is then stopped by a second cam disc which opens the holding contact.
