ABSTRACT:
A device for counting events, such as deposit of coins, providing a control signal after an easily preset number of events has been counted. A binary counter has a parallel output register, with a simple switch and diode connected between each output terminal of the register and a common signal conductor. Individual switches are set to the binary number corresponding to the desired count, so that the voltage on the common conductor changes when the count equals or exceeds the binary preset number. When the circuit receives on electrical signal to be counted, a delay circuit prevents counting for some minimum interval of time, to prevent false counts due to switch bounce or other disturbances which may be related to the event. Energy is stored within the device to maintain the stored count for a short period of time in the event of power interruption between receipt of a first signal to be counted and provision of a control signal when the preset number of counts has been reached.
