Abstract
This bill validator accumulates bills between a pair of spaced parallel stationary members forming an entrance of a bill accumlating box and a bill compressing plate provided in the bill accumulating box. A push member is disposed in the vicinity of the entrance of the accumulating box. This push member is actuated by a reciprocating mechanism to push a bill positioned at the entrance into the accumulating box and thereby add this bill to a stack of accumulated bills. Constant springs are provided in association with the bill compressing plate. These constant springs enclose a bill accumulating space in the accumulating box with their winding shafts being pivotably connected on the accumulating box and their taken out ends being fixedly secured to the bill compressing plate. The constant springs urge the bill compressing plate to the entrance of the accumulating box with a constant pressing force. Since the pressing force of the constant springs can be made small regardless of a maximum possible number of bills to be accumulated, the driving force required for reciprocating the push member against this spring force can be made small.
