ABSTRACT:
A detecting apparatus for detecting discrepancy in number of stacked coins provided for a coin wrapping machine including wrapping rollers for winding a wrapping film having a larger width than the height of stacked coins around stacked coins of a predetermined number so that there remain crimp regions crimpable above and below the stacked coins and an upper crimp claw and a lower crimp claw movable in the vertical direction, the upper crimp claw and the lower crimp claw being for crimping the crimp regions of the wrapping film by being moved toward each other and holding the stacked coins therebetween, the detecting apparatus for detecting discrepancy in number of stacked coins further including an upper arm for supporting the upper crimp claw, a lower arm for supporting the lower crimp claw, a rack extending vertically and fixed to one of the upper arm and the lower arm, a pinion rotatably mounted on the other of the upper and lower arms and engageable with the rack, an absolute type rotary encoder connected to the pinion for outputting absolute position data in accordance with the position of rotation thereof, and a detector for detecting any discrepancy in the number of the stacked coins by calculating the sum of distances traveled by the upper and lower crimp claws based upon the absolute position data output from the rotary encoder. The thus constituted detecting apparatus can detect discrepancies in the number of the stacked coins with high accuracy.
