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.
In a paper sheet counting machine comprising: a counting section including a paper holder made movable between an open stand-by position in which the machine in ready to receive paper sheets for counting and a closed holding position for holding the paper sheets, a rotatable suction drum, and a plurality of rotatable suction cylinders carried on said suction drum for sucking the paper sheets one by one so as to count the number of the same; and a comparator for comparing the actual counted number with a preset number, a counting section shielding device comprising: a pair of double-leaf type sound-proof covers made movable between an open position for providing easy access to said counting section and a closed position in which the shielding device extends above said counting section so as to shield the same and prevent the escape of noise and dust; an electric circuit for generating closing signals after said paper holder is charged with the paper sheets and for generating opening signals when the comparison by said comparator shows the counted number to be equal to the preset number but not when the comparison shows said numbers to be unequal, said electric circuit including a resetting button made manually operable for generating the opening signals of said electric circuit; and drive means made responsive to both the closing signals of said electric circuit for closing said sound-proof covers and the opening signals of the same for opening said sound-proof covers as well as said paper holder.
