Definition

This is the generic and residual class for control mechanisms adapted to be actuated by check means, and whose function is to govern the operation of an associated machine or system. This class provides for such control mechanisms, per se, the combination of such control mechanism with either a machine or system, a cabinet structure containing the control mechanism peculiar to this class (e.g., a value accumulator, a coin chute, etc.), or a check, per se, designed specifically to actuate a control mechanism.

(1) Note. The term "check," as used herein, refers to an object having or representing a monetary value which can be measured or verified, and includes coins and substitutes therefor which have an analogous function. (2) Note. In disclosures of parts or the whole of a machine or system and check-actuated control mechanism for governing the operation therefor, the mere inclusion of "coin- (or other check) controlled means" as an element in claims setting forth specific structure of the machine or system, but in which no specific feature of the control mechanism is claimed, is not sufficient to justify placement in this class. The disclosure will be placed in the class in which the machine or system is classifiable.
