An image reading apparatus includes a lower unit, and a discharge tray and an upper unit that pivot with respect to the lower unit. An axis center of the discharge tray and an axis center of the upper unit are common, the image reading apparatus includes a first damping portion that damps pivoting of the discharge tray in at least an opening direction, and a second damping portion that damps pivoting of the upper unit in at least a closing direction, and the upper unit is configured to engage with the first damping portion, and, when the upper unit is closed from a state in which at least the discharge tray and the upper unit are opened, in addition to a damping force of the second damping portion, a damping force of the first damping portion is applied to the upper unit.

An image reading apparatus includes an image sensor, a document feeder, and a processor. The document feeder includes a first driving device, a second driving device, a third driving device, a first sensor, and a second sensor. The first driving device includes a pick-up member to move documents from a tray to a document conveying path using a driving force through a first clutch. The second driving device is to move the tray with the documents to a side of the pick-up member using a driving force through a second clutch. The third driving device to move the documents along the document conveying path onto the image sensor using the driving force of the motor The first and second sensors detect the documents on the document conveying path. The processor controls an operation of the first clutch based on the signals of the first and second sensors.

An image reading apparatus includes a transport unit, a reader, a detector, and a controller. The transport unit transports a document. The reader reads the transported document. The detector detects whether or not a document bundle prior to being transported is present. While a document in a first document bundle corresponding to a first job is being transported, if the detector detects that a document in a second document bundle corresponding to a second job as a subsequent job is loaded, the controller actuates the transport unit until all documents in the first document bundle are output.

A scanner includes an image capturing module, a drive roller assembly, an idle roller assembly, and a guiding structure. The image capturing module is for capturing an image of an object. The drive roller assembly is for driving the object to move along a feeding direction. The idle roller assembly is for preventing a moving direction of the object away from the feeding direction by resiliently pressing the object. A feeding passage is formed between the drive roller assembly and the idle roller assembly. The guiding structure is disposed in front of the feeding passage and for guiding a normal direction of a leading edge of the object to be oblique relative to the feeding direction at an oblique angle. Therefore, the present invention can effectively reduce variation of a resistance force acting on the object as the object moves in the feeding path, which prevents image distortion.

Provided is an image reading device includes a document transport device that sequentially transports a plurality of documents one by one, and the image reading device sequentially reads the plurality of documents transported by the document transport device one by one. The image reading device includes a document discharge tray, a document discharge detector that detects whether or not a document of the plurality of documents is discharged to the document discharge tray, a notifier that notifies that the document of the plurality of documents discharged to the document discharge tray is forgotten to take, and a controller that activates the notifier if it is determined that a last document among the plurality of documents is read and the document discharge detector detects that the document of the plurality of documents is discharged to the document discharge tray.

Example implementations relate to an edge sensing apparatus. For example, an edge sensing apparatus consistent to the present disclosure may include a reflector in a beam path of a retroreflective sensor. The edge sensing apparatus consistent with the present disclosure may include a cover glass located between the retroreflective sensor and the reflector. The edge sensing apparatus consistent with the present disclosure may include a media feeder to feed a media along a media path between the cover glass and the retroreflective sensor.

A medium conveying apparatus includes an imaging unit provided to be movable in a direction perpendicular to a conveying surface for conveying a medium, to image the medium, a roller pair provided on an upstream side of the imaging unit in a medium conveying direction, the roller pair including a first roller provided to be movable in a direction perpendicular to the conveying surface, and a second roller facing the first roller, and a conveyance guide provided on a rotation shaft of the first roller, to move in conjunction with a movement of the first roller. The conveyance guide includes a guide surface extending at least from a downstream end portion of a nip portion of the roller pair to an upstream end portion of the imaging unit in the medium conveying direction and being flush with a lower surface of the imaging unit.

An image reading apparatus includes an image reading sensor, a transparent plate, a guiding member, a first roller pair, and a second roller pair provided upstream of the first roller pair with respect to a sheet feeding direction. The first roller pair and the second roller pair are disposed so as to nip a sheet in each of nips of the first roller pair and the second roller pair when a leading end of the sheet enters between the guiding member and the transparent plate.

A document reading apparatus includes a first discharge tray that assumes a closed state or an open state, by pivoting about a first pivotal shaft, a first transport route linearly extending from a document tray to the first discharge tray, a first reading device that reads an image of the document, a transport device that transports the document through the first transport route, and a controller that, when an instruction to read the document is inputted to an input device, restricts the transport device from transporting the document and the first reading device from reading the image, when the closed state or a full state of the first discharge tray is detected by a first detector, and allows the transport device to transport the document and the first reading device to read the image, when neither of the closed state and the full state is detected by the first detector.

An image reading device includes a plurality of conveyance rollers to convey a sheet, a motor to drive the plurality of conveyance rollers, an image reading unit to read an image of the sheet, a control device to perform a stop control that stops the sheet in a course of a conveyance path, and a clutch to transmit a driving force of the motor. A first conveyance roller group includes at least one of the plurality of conveyance rollers upstream from a leading end of the sheet stopped by the stop control in a conveyance direction, to which the driving force is transmitted via the clutch. A second conveyance roller group includes at least one of the plurality of conveyance rollers downstream from the leading end of the sheet stopped by the stop control in the conveyance direction, to which the driving force is transmitted without the clutch.
