摘要： A CPU checks a detecting state of a document set sensor at a point when the trailing end of a document sheet is assumed to pass through a separating position at which the document sheet is separated by a separation roller, based on a document length determined based on a detecting output from an abutting sensor. If the document set sensor does not detect a document sheet, the CPU determines that the next document sheet is not present. If the document set sensor detects a document sheet, the CPU checks a detecting state of the document presence detecting sensor. If the document presence detecting sensor detects a document sheet, the CPU determines that the next document sheet is present.

摘要翻译： 在文件片的尾端被假设通过分离位置的情况下，CPU检查文档集传感器的检测状态，在该分离位置，基于基于 来自邻接传感器的检测输出。 如果文档集传感器未检测到文档纸张，则CPU确定下一个文档页不存在。 如果文档集传感器检测到文档，则CPU检查文档存在检测传感器的检测状态。 如果文件存在检测传感器检测到文档片材，则CPU确定下一个文档片材存在。

摘要： A sheet stacker includes a sheet ejector, a sheet stack portion, and air blowers. The sheet ejector ejects a sheet. The sheet stack portion stacks the sheet ejected by the sheet ejector. The air blowers blow air from blow ports toward the sheet ejected from the sheet ejector. Each of the air blowers includes an air generator, an air guide, a first blow portion, a second blow portion, and a switcher. The air generator generates the air. The air guide guides the air to each of the blow ports. The first blow portion blows the air toward the sheet. The second blow portion blows the air in a direction different from a direction in which the first blow portion blows the air. The switcher performs switching so that the air guide guides the air to one of the first blow portion and the second blow portion.
