20140191467 | Image Scanning Device - An image scanning device includes a scanning unit configured to scan, at a scanning position, an image of a document, a first discharge portion, a second discharge portion, a conveying unit configured to selectively convey the document along a first conveying path from the scanning position to the first discharge portion, and along a second conveying path from the scanning position to the second discharge portion, a driving unit configured to generate a driving force for driving the conveying unit, and a path switching unit configured to receive the driving force generated by the driving unit such that the path switching unit moves between a first position for guiding the document toward the first discharge portion, and a second position for guiding the document toward the second discharge portion. | 07-10-2014 |
20140293379 | Sheet Conveying Device and Image Reading Apparatus - 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. | 10-02-2014 |
20140313554 | Image Reader - An image reader is provided, which includes a light guide unit forming an optical path to guide light emitted by a first light emitting portion of a first reading unit to a second light receiving portion of a second reading unit, which optical path passes across a feeding path in a detection position such that a document sheet passing through the detection position on the feeding path blocks the light on the optical path, and a controller determining that a leading end or a trailing end of the document sheet passes through the detection position in response to detecting a change in a light receiving state of the second light receiving portion when the document sheet passes through the detection position with the first light emitting portion emitting light and a second light emitting portion of the second reading unit not emitting light. | 10-23-2014 |
20140320936 | IMAGE READING APPARATUS PROVIDED WITH IMAGE SENSOR CONTAINED IN SLIDABLE CARRIAGE - An image reading apparatus includes: a contact glass setting a manuscript thereon; an image sensor extending in a first direction and having a reading surface which faces the contact glass for reading an image from the manuscript on the contact glass; a rail member extending inside the apparatus main body in a second direction perpendicular to the first direction; a carriage having a sensor container to contain the image sensor, a taper end portion formed in an end portion in the first direction to become smaller in height toward the end side, and an opening formed in the bottom of the sensor container on the taper end portion side; a biased portion adjacent to the reading surface of the image sensor in the second direction; and a biasing member biasing the image sensor toward the contact glass via the biased portion. | 10-30-2014 |
20150043045 | IMAGE READING APPARATUS - An image reading apparatus includes: a contact glass provided at an upper surface of a main body of the apparatus to set a manuscript thereon, an image sensor being positioned below the contact glass and having a reading surface on contact glass side for reading an image from the manuscript on the contact glass, a carriage supporting the image sensor accommodated in a sensor container formed to have a recess open to the contact glass side, a rail member slidably supporting the carriage, and a biasing member biasing the image sensor to the contact glass side via a biased portion adjacent to the reading surface of the image sensor. An upper end of the biasing member is positioned below the contact glass and above the lower surface of the image sensor. | 02-12-2015 |
