Claim:
1. A paper-sheet counting machine comprising: a counting unit configured to count paper sheets and to recognize the paper sheets; a stacking unit configured to stack therein the paper sheets that have been counted by the counting unit, an opening being provided at the stacking unit; a reject unit configured to receive the paper sheets respectively recognized as reject paper sheets by the counting unit and fed thereto from the counting unit; a shutter configured to close the opening provided at the stacking unit; a shutter drive unit configured to drive the shutter to open and close the opening provided at the stacking unit; a control unit configured to control the shutter drive unit; a placing unit configured to place thereon the paper sheets to be respectively counted by the counting unit, for allowing such paper sheets, respectively placed on the placing unit, to be fed, one by one, to the counting unit; a first paper-sheet detection unit configured to detect whether or not the paper sheets are placed on the placing unit; and a second paper-sheet detection unit configured to detect whether or not the paper sheets are stacked in the reject unit; wherein after the first paper-sheet detection unit detects that there is no paper sheet remaining on the placing unit, and all the paper sheets on the placing unit have been fed to and stacked in the stacking unit and the reject unit, where at least one paper sheet in the reject unit is detected by the second paper-sheet detection unit, the control unit does not open a closed shutter by controlling the shutter drive unit until satisfying a condition that the second paper-sheet detection unit detects that there is no paper sheet in the reject unit, and when the control unit detects the condition is satisfied, the control unit opens the closed shutter automatically without manual instruction for opening the closed shutter.
