ABSTRACT:
A sheet material stacking apparatus comprises a shift sensor configured to detect the sheet conveyed by a branching path, a drop-down checking sensor configured to detect that sheet which reaches a scraping-out plate through the rotation of a rotatable blade-type runner, and a transport controller configured to, after a passage of a predetermined time following the detection of the sheet by the shift sensor, start detecting the sheet by using a drop-down checking sensor, and to stop stacking the sheet when the drop-down checking sensor detects no sheet.
