Apparatus for extraction of desired number of sheets for use in a sheet counting machine

摘要

An apparatus for extraction of a desired number of sheets for use in a counting machine for paper sheets and the like, wherein paper sheets held in a stack between a holder and a paper-pressing bar are sucked and counted one at a time by respective suction heads provided on a rotational cylinder, a desired number of counted sheets on the side of the pressing bar being extracted from the machine by a separator which separates the counted sheets from the remaining sheets in a stack when the desired number of sheets have been counted. The apparatus for extracting a desired number of sheets comprises an operational mechanism incorporating a solenoid and associated members which is operated in cooperation with the action of said separator which separates the desired number of counted paper sheets from the remaining paper sheets so as to move said paper-pressing bar in a direction away from said holder and which can be reset to its original state. The associated members includes a link connecting the pressing bar for holding the paper sheets in cooperation with the holder with the solenoid, and a no paper sheet detecting device comprising an LED and a photosensor positioned so that it operates when the pressing bar is away from the holder and paper sheets are not present on the pressing bar.
