    Abstract: An image reading device reads an image of an original document and includes a conveyance roller, an image reading section, a first determination section, a second determination section, and a conveyance stopping section. The conveyance roller conveys the original document. The image reading section reads the image of the original document. The first determination section determines whether or not the original document has a punched hole based on the image read by the image reading section. The second determination section determines, upon determination that the original document has the punched hole, whether or not the punched hole is to travel on an edge of the conveyance roller. The conveyance stopping section stops conveyance of the original document upon determination that the punched hole is to travel on the edge of the conveyance roller.

    Abstract: A document conveying device (9) includes a sheet feeding tray (44), a discharge tray (43) provided below the sheet feeding tray (44), a feeding roller (51), a conveying mechanism (35), a lifting mechanism (38) which lifts and lowers the sheet feeding tray (44), a discharge tray document sensor (18) which detects the document on the discharge tray (43), and a control part (10) which controls the lifting mechanism (38) such that the document placed on the sheet feeding tray (44) is pressed against the feeding roller (51) when the conveying mechanism (35) conveys the document. The control part (10) controls the lifting mechanism (38) to lower the sheet feeding tray (44) by a larger amount in a case where the document is not detected by the discharge tray document sensor (18) when power is turned on than a case where the document is detected by the discharge tray document sensor (18).

    Abstract: A document conveying device includes a document tray, a first rotary member, a first motor, a second rotary member, a second motor, a document feed sensor, and a controller. The controller counts a counted time from the time point that the first motor starts to rotate until the leading end of a document reaches the document feed sensor. When the time resulting from subtracting the counted time from a required sheet-to-sheet time interval is longer than the required speed change time, the controller performs deceleration and post-deceleration acceleration for the first motor. The required speed change time is the time required for speed change from the first rotation speed to the second rotation speed.

    Abstract: A sheet conveyance mechanism in the present disclosure has a feeding portion, a pair of registration rollers, a first sensor, a second sensor, and a conveyance control portion. The feeding portion has a drive roller. The registration rollers are disposed in a downstream side of the feeding portion. The first and second sensors detect presence of a sheet. If after a sheet is detected by the first sensor, the sheet is not detected by the second sensor by a time when a first period elapses, the conveyance control portion starts a slowdown of a rotation speed of the drive roller. If the sheet is detected by the second sensor by a time when a second period elapses after the slowdown of the rotation speed of the drive roller starts, the conveyance control portion returns the rotation speed of the drive roller to a rotation speed before the slowdown.
