ABSTRACT:
The counter means serve for a counting of events. A counter is provided as well as a code detector adapted to receive a coded punched card in a predetermined position. Counter control means are operable to control said counter in response to the arrival of said card in said predetermined position. Said code detector comprises replaceable, pivoted code detector elements, which represent a predetermined code and are adapted to enter holes in said punched card if, and only if, said holes also represent said predetermined code. Said code detector prevents a movement of said card to said predetermined position unless said code detector elements have entered said holes in said card.
