Abstract
Herein disclosed in a paper sheet counting machine which comprises: position detecting means for detecting that suction tubes are in a stand-by position and in a start position; vacuum pressure detecting means for detecting the vacuum pressure prevailing in the suction tubes; and a control unit for driving and controlling a counter motor, a holder motor and a pump motor in response to signals which are fed from the position detecting means and the vacuum pressure detecting means. When the holder is in an open position, the suction tube is set in the stand-by position. After the holder is set in a closed position, the suction tube is then set in the start position to block and seal its inside from the outside. Then, a vacuum pump is driven so that the counting operations are started when the vacuum pressure in the suction tube reaches a predetermined level.
