Counting section shielding device for paper sheet counting machine

Abstract

A counting section shielding device for shielding the counting section of a paper sheet counting machine including a paper holder for holding paper sheets to be counted, a plurality of rotatable suction cylinders carried on a suction drum for sucking the paper sheets one by one so as to count the number of the same. The counting machine includes a comparator for comparing the actual counted number of the paper sheets with a preset number. The shielding device includes a pair of sound-proof covers which can be opened to provide easy access to the inside of the counting section so that the paper holder may be charged with the paper sheets and which can be closed to extend above the counting section so that this section may be shielded to prevent escape of noise and dust. Further included is an electric circuit which is made operative to effect the closing operations of the sound-proof covers and to effect the opening operations of the sound-proof covers as well as the paper holder in case that the comparison by the comparator shows the counted number to be equal to the preset number. In case the comparison shows the numbers to be unequal, a resetting signal is manually operated to effect the opening operations of the sound-proof covers and the paper holder.
