摘要： An original transport device having paper discharge rollers constituted by a fixing roller in a fixed position and a separate/contact roller separating from/making contact with the fixing roller, for sandwiching and transporting an original in an original transport path, includes: a swinging support member supporting the separate/contact roller and swinging so that the separate/contact roller is separated from/press-contacted to the fixing roller; an operation unit coupled to the swinging support member to swing the swinging support member; and a locking member locking the swinging support member to stop the swing thereof. The locking member locks the swinging support member so that the paper discharge rollers are in a separate state or a press-contact state when the operation unit is driven, and after the operation unit is turned off, the locking member maintains the separate state or the press-contact state during driving of the operation unit.

摘要： An image-forming apparatus includes an image-reading unit. The image-reading unit includes a first member and a second member. The image-reading unit includes an original-document-feeding apparatus that conveys an original document from an original-document-loading tray to a discharge tray via a read position. In the first member and the second member, a first conveyance passage along which the original document is conveyed to the read position and a second conveyance passage along which the original document is conveyed from the read position to the discharge tray are formed. The second member includes at least two conveyance rollers. Between the two conveyance rollers, there are opening edges for partly allowing access to the second conveyance passage. The second member includes a lid for covering an opening that is defined by the opening edges.

摘要： A sheet feed apparatus includes a sheet separation unit, and the sheet separation unit includes a separation roller that is provided so as to be brought into contact to an outer peripheral surface of a sheet feed roller, and separates a sheet fed by the sheet feed roller into one. The sheet separation unit comprises a hook for rotatably supporting the sheet separation unit in a main body casing of the sheet feed apparatus and an engaging claw that makes the sheet separation unit engage with the main body casing. Therefore, the sheet separation unit is held in the main body casing detachably.

摘要： An image forming apparatus has a power-saving mode in which the image forming apparatus is switched from a normal power consumption state to a low power consumption state where less energy is supplied than in the normal power consumption state. This image forming apparatus includes a detection unit configured to detect an operating state of the image forming apparatus, and a memory unit configured to store a detection result by the detection unit. In the power-saving mode, the detection unit detects an operating state of the image forming apparatus, and the memory unit stores a detection result by the detection unit. When the image forming apparatus returns from the low power consumption state in the power-saving mode to the normal power consumption state, control of a return operation for the image forming apparatus from the power-saving mode is executed, based on the detection result by the detection unit stored in the memory unit.
