摘要:
A conveying mechanism is disposed inside a housing of an image scanning device and is configured to convey the sheet along a common path to the scanning position in a first direction, and to convey the sheet having passed the scanning position selectively along a return path in a second direction and along a one-way path in the first direction. A scanning unit disposed inside the housing scans, at the scanning position, an image of a sheet. The discharge cover is openably and closably disposed in the housing and is configured, when open relative to the housing, to define a discharge port and receive the sheet conveyed along the one-way path and discharged through the discharge port. The maintenance cover is openably and closably disposed in the housing and is configured, when open relative to the housing, to expose the one-way path and the return path.

A sheet output device includes a sheet receiver and a group of rollers. The group of rollers includes a plurality of output rollers arranged in the widthwise direction of the sheet and a plurality of pinch rollers arranged upward of the plurality of output rollers. The plurality of pinch rollers pinch the sheet with the plurality of output rollers and transport the sheet onto the sheet receiver. The sheet output device further includes at least one corrugation roller which is disposed between corresponding two of the plurality of output rollers and which has a diameter larger than the plurality of output rollers. The plurality of output rollers are rotatable relatively with respect to the at least one corrugation roller. The at least one corrugation roller rotates by being pushed by a leading end of the transported sheet.

In an image reading apparatus, it is judged whether an original sheet is a first sheet type, whose sheet length is longer than or equal to a first conveyance distance and shorter than a second conveyance distance, and a second sheet type, whose sheet length is longer than or equal to the second conveyance path, the first conveyance distance being a distance between a first conveyance roller and a second conveyance roller, the second conveyance distance being a distance between a supply roller and the second conveyance roller. At least one of a leading-edge arriving timing; a trailing-edge arriving timing; and a sub-scanning magnification is set dependently on the judged result. An image is read from the original sheet by using an image reading unit and a conveyance unit based on the set at least one of the leading-edge arriving timing; trailing-edge arriving timing; and sub-scanning magnification.

An image reading apparatus has a separation section configured to supply a sheet one by one, at least three driving rollers arranged downstream of the separation section in a sheet conveying direction and configured to convey the sheet, at least three driven rollers configured to be urged by the driving rollers and driven to rotate by rotation of the driving rollers, respectively, and an image reader unit configured to read an image of the sheet conveyed in the conveying direction. Sheet conveying forces by one of at least three driven rollers and one of at least three driving rollers arranged at the central portions in the sheet width direction is greater than sheet conveying forces by others of the at least three driven rollers and others of the at least three driving rollers arranged at both side portions in the sheet width direction.

An image reading apparatus, including a driving unit, a separator unit, a conveyer unit, a reader unit, a reducer unit, a size detecting unit; and a controller is provided. The separator unit includes a drive shaft, a contact member, and a clutch. The controller manipulates the conveyer unit via the driving unit to convey the sheet at a first conveying speed when the size of the sheet detected by the size detecting unit is greater than a predetermined size. The controller manipulates the conveyer unit via the driving unit to convey the sheet at a second conveying speed, which is lower than the first conveying speed, when the size of the sheet detected by the size detecting unit is one of smaller than and equivalent to the predetermined size.

A sheet conveyor device may include a first portion configured to move, a cam configured to move in response to movement of the first portion, and a guide portion configured to move between first and second positions in response to the movement of the cam, to choose a first or second conveying path for a sheet. The cam may cause the guide portion to remain in position even if the first portion is moved a small amount, thereby helping to reduce the likelihood of paper jams arising from undesired movement of the guide portion.

An image reading apparatus having a sheet path, which includes two ejection paths, is provided. The sheet path is switchable between the two ejection paths by a switchable member. An outlet cover arranged on a casing of the image reading apparatus is movable between a closed position and an open position to open and close an outlet of the second ejection path. When the outlet cover moves from the closed position to the open position, and before the switchable member switches the sheet path from the first ejection path to the second ejection path, switching of the sheet path from the first ejection path to the second ejection path is detectable.

In an image reading apparatus, it is judged whether an original sheet is either one of a first sheet type, whose sheet length is longer than or equal to a first conveyance distance and shorter than a second conveyance distance, and a second sheet type, whose sheet length is longer than or equal to the second conveyance path, the first conveyance distance being distance between a first conveyance roller and a second conveyance roller, the second conveyance distance being distance between a supply roller and the second conveyance roller. The original sheet is conveyed at a separation timing, when the original sheet separates away from the supply roller, at a speed that is smaller for a case where the original sheet is of the first sheet type than for a case where the original sheet is of the second sheet type. An image is read from the conveyed original sheet.

摘要:
A sheet conveying device including: a separating roller; a separating piece; and conveying rollers. The separating roller conveys each sheet along a predetermined conveying path in a conveyance direction. The separating piece provides a first nip position in cooperation with the outer peripheral surface of the separating roller for nipping a sheet or sheets therebetween. The conveying rollers are provided at positions downstream of the separating roller in the conveyance direction and provide a second nip position where the sheet is nipped therebetween for conveying the sheet conveyed by the separating roller in the conveyance direction. An imaginary flat plane is defined by connecting the first nip position and the second nip position. The separating piece has a portion positioned downstream of the first nip position and protruding toward the separating roller beyond the imaginary flat plane.
