20090140490 | DOCUMENT CONVEYING DEVICES AND IMAGE READING DEVICES COMPRISING SUCH DOCUMENT CONVEYING DEVICES - A document conveying device includes a conveying path and a feed unit. The feed unit includes a tray including a document positioning surface configured to receive documents thereon, in which the document positioning surface has a hole formed therethrough. The feed unit also includes a separation roller which is rotatably supported by a drive shaft extending in a direction orthogonal to a document conveying direction and is configured to contact an uppermost document of the documents and to separate and convey the uppermost document. The separation roller includes a first end and a second end opposite the first end. Moreover, the feed unit includes a document sensor including a detection portion configured to detect the documents and to selectively move between a first position in which the detection portion projects from the document positioning surface via the hole and a second position in which the detection portion is retracted from the document positioning surface via the hole. In addition, the feed unit includes a casing pivotably mounted on the drive shaft. The casing includes a plate extending adjacent to the first end of the separation roller in the document conveying direction, and the first end of the separation roller and the detection portion are positioned closer to the second end of the separation roller than the plate of the casing. | 06-04-2009 |
20130187327 | SHEET-SUPPLY CASSETTE, AND IMAGE RECORDING APPARATUS INCLUDING SHEET-SUPPLY CASSETTE - A sheet-supply cassette including a main member open upward and adapted to store a plurality of recording sheets stacked on each other, each of which is separated from the other recording sheets, and is fed in a sheet-feed direction, by a sheet feeder; an inclined sheet-separate plate provided in a downstream-side portion of the main member as seen in the sheet-feed direction, and which cooperates with the sheet feeder to separate the each recording sheet from the other recording sheets; and a plurality of back-surface support portions which are formed integrally with the downstream-side portion of the main member, such that the back-surface support portions are distant from each other in a perpendicular direction substantially perpendicular to the sheet-feed direction. The inclined sheet-separate plate is detachably attached to the back-surface support portions such that a back surface of the inclined sheet-separate plate is supported by the back-surface support portions. | 07-25-2013 |
20140085688 | Cable Wiring Structure and Image Reading Device - A cable wiring structure includes: a base member; a movable member configured to reciprocate in a first direction and in a second direction relative to the base member; a cable; a tension applying member, which is attached to the movable member and is movable in the first direction and in the second direction relative to the movable member, wherein when the movable member moves in the second direction, the tension applying member is coming in contact with an inner circumference of the curved portion to apply tension to the cable in response to movement of the movable member; and a load adjustment portion, which is configured to increase a load that is applied between the tension applying member and the movable member in a case where the movable member moves in the second direction as compared with a case where the movable member moves in the first direction. | 03-27-2014 |
20140118802 | Image Reading Apparatus - An image reading apparatus configured to reduce a force required for moving a document cover to an open position is provided. The image reading apparatus includes a document table having a top surface and a reading area and a document cover that is configured to pivot, around an axis extending in a first direction, between a closed position and an open position. The document cover includes a sheet. The top surface has a marginal area which is located outside of a reading area on a side opposite to the axis. The marginal area includes a contact area and a non-contact area which are arranged in the first direction. When the document cover is in the closed position, the top surface in the contact area contacts the sheet, and the top surface in the non-contact area does not contact the sheet. | 05-01-2014 |
20140151952 | Sheet Conveyor Device - A sheet conveyor device includes a conveyor that convey a sheet along a conveyance path in a conveying direction, a sheet stack portion that receives the sheet conveyed by the conveyor, and a conducting member. The conveyor includes an ejection roller that ejects the sheet to the sheet stack portion. The conducting member includes a contact portion, disposed along the conveyance path downstream of the ejection roller, that comes into contact with the sheet conveyed by the conveyor, and a discharge portion that discharges static electricity transferred to the contact portion by contact between the sheet and the contact portion. | 06-05-2014 |
20140151953 | Sheet Conveyor Device - A conveyor device includes a conveyor including a conveyor roller to convey a sheet along a conveyance path, a cover movable between a closed position where the cover covers the conveyor roller and an open position where the cover is separated from the conveyor roller. The conveyor further includes a pinch roller urged toward the conveyor roller when the cover is in the closed position. When the cover is in the closed position, the conveyor roller and the pinch roller define a nip point along the conveyance path. The conveyor device includes a holder supported by the cover and to rotatably support the pinch roller and an urging member disposed between the cover and the holder to move the holder away from the cover to urge the pinch roller toward the conveyor roller when the cover is in the closed position. | 06-05-2014 |
20140153068 | IMAGE READING APPARATUS - The instant application discloses an apparatus including an image forming unit and an image reading apparatus. The image forming unit may be disposed adjacent to the base wall of the image reading apparatus. The image reading apparatus may include a base member including the base wall and a peripheral wall protruding orthogonally from the base wall to define an accommodation region; a movable member configured to reciprocate between one end portion of the accommodation region and another end portion of the accommodation region; a reading unit supported by the movable member; a cable having a first extending portion, a curve portion, and a second extending portion; and a contact reduction portion configured to reduce contact of the second extending portion of the cable with a side wall of the peripheral wall. Various embodiments of the contact reduction portion are also disclosed. | 06-05-2014 |
20150274448 | SHEET CONVEYING DEVICE - A sheet conveying device includes: a supporter which support a sheet to be supplied or a discharged sheet. The supporter includes: a first cover pivotable between a closed position and an open position and capable of supporting the sheet when the first cover is located at the open position; and a second cover pivotable between a first position and a second position and constituting a portion of an exterior of the sheet conveying device with the first cover when the second cover is located at the first position. The second cover has a first end portion contactable with the first cover located at the closed position. The first end portion is kept in contact with the first cover throughout a period in which the second cover is pivoted from the first position to the second position. | 10-01-2015 |
