Solid state monetary accumulator, credit storage, and selector logic circuit

Claim 1

A monetary accumulator, credit storage, and selector logic circuit comprising, first circuit means for providing logic pulse signals which correspond to the value of coins sensed thereby, a plurality of memory circuits having inputs coupled to said first circuit means, said memory circuits providing discrete output terminals each corresponding to a different total accumulation of coins as registered by said first circuit means, each of the said output terminals arranged for connection to selector means to enable said selector means so that selections can be made corresponding to the total accumulation of coins as represented at the output terminal so energized, each of said plurality of memory circuit is formed by first and second cross-coupled logic circuits, each having a pair of inputs, one input of said first logic circuit being coupled to said first circuit means, one input of said second logic circuit being coupled to a second circuit means, and the output terminals of each of said first and second logic circuits being cross-coupled back to the other input of the other of said first and second logic circuits, to form an R-S flip-flop circuit, a capacitor connected between the output terminals of each of said logic circuits and ground potential, and said second circuit means being connected to said plurality of memory circuit and arranged for connection to said selector means to provide a reset signal to said plurality of memory circuits upon actuation of any one of the selector means.
