摘要： PROBLEM TO BE SOLVED: To provide a sheet material conveying device which can make the transition to a power saving mode while storing a sheet material in a sheet storing unit, and if the stored sheet material is collected, which can cancel the power saving mode only by setting a new sheet material in the sheet storing unit, and to provide an image reading device with the same, and an image forming device.SOLUTION: A sheet material conveying device controls a configuration of clamping a manuscript MS between a movable manuscript table 53b and a pick up roller 80, into a clamping state when a manuscript set sensor 63 returns a detection state of manuscript present, and into a clamping release state when the manuscript set sensor returns a detection state of manuscript absent. In an ADF 51 that makes the transition to a power saving mode if any drive command is not input for a predetermined time, and cancels the power saving mode when a detection state of the manuscript set sensor 63 is changed to effective from non-effective during the power saving mode, the movable manuscript table 53b is lowered to release the clamping state before executing the power saving mode.

摘要： PROBLEM TO BE SOLVED: To provide an automatic document feeder capable of reducing a processing time required to determine a rear end of a document and a hole on a document to reduce a conveyance interval between documents, an image reading device, and an image forming apparatus.SOLUTION: In an automatic document feeder, a rear end detection sensor 301 upstream in a document conveyance direction has a detection range set wider than detection ranges of any of document detection means of an abutment sensor 11, a document width sensor 13, a reading inlet sensor 15, and a resist sensor 17. In a direction orthogonal to the document conveyance direction, the rear end detection sensor 301 and the plurality of document detection means are arranged with each other such that all the detection ranges of the plurality of document detection means are included in the detection range of the rear end detection sensor 301. When a controller determines, on the basis of a detection result of the rear end detection sensor 301, that a hole is not present on a document, the controller does not determine the presence of a hole on the document and determines only the passage of the rear end of the document on the basis of detection results of the document detection means.
