Medium feeding device and image reading apparatus

An image reading apparatus includes a feeding roller that includes a first roller and a second roller provided at an interval in a width direction intersecting a medium feeding direction, and feeds a sheet from a placing section; and a skew detection section that detects skew of the sheet fed from the feeding roller. Skew is corrected by giving a difference between a rotation speed of the first roller and a rotation speed of the second roller with respect to at least one of the relevant sheet detected by the skew detection section and subsequent sheets fed following the relevant sheet based on a skew amount in the sheet.

Pick up device for using in automatic feeder

A pick-up device disposed between an input tray and a feeding path includes a paper feeding unit for feeding paper, a separation roller disposed opposite to the paper feeding unit, a blocking arm disposed between the input tray and the paper feeding unit and configured to be switchably disposed between a blocking position for blocking the paper and a feeding position for passing the paper through the feeding path, and a guiding arm disposed in the feeding path through a pivot shaft and having a guiding portion. The pivot shaft is located upstream of the separation roller, and the guiding portion is swingably disposed in a seam space formed by the paper feeding unit and the separation roller.

The medium transporting device is arranged so as to face the feeder for feeding the medium in the transporting direction and the surface of the medium transported in the transporting direction, and detects the motion of the medium in the two-dimensional coordinate system including the first axis and the second axis. The two-dimensional sensor is provided in a state in which the first axis and the second axis are inclined with respect to the transporting direction.

Media feeding apparatus and image reading apparatus
11639278 · 2023-05-02 · ·

A media feeding apparatus includes a media mounting section, a first feed roller, a media pressing section for pressing media sheets against the first feed roller, and a pressing force adjuster for adjusting the pressing force of the media pressing section. The controller sets the pressing force of the media pressing section to first pressing force and drives the first feed roller and the second feed roller in a forward rotation direction, and in a case in which the first detector detects a passage of a leading edge of the media sheet and the second detector detects no passage of the leading edge of the media sheet after predetermined first set time has passed, the controller continues the rotation of the first feed roller and the second feed roller with second pressing force of the media pressing section greater than or equal to the first pressing force.

Medium conveying apparatus to detect multi-feed based on continuous overlap portion
11820624 · 2023-11-21 · ·

A medium conveying apparatus includes a conveying roller to convey a medium, an overlap detection sensor, a processor to detect an overlap portion in which it is determined that an overlap has occurred on the medium based on a detection output by the overlap detection sensor for the medium conveyed by the conveying roller, calculate an overlap length where the overlap portion is continuous based on a detection result of the overlap portion, determine whether a multi-feed has occurred based on the overlap length, and execute an abnormal processing for the multi-feed based on a determination result of the multi-feed. The processor determines that a first overlap portion and a second overlap portion are continuous when a distance between the first overlap portion and the second overlap portion is within a predetermined distance in calculating the overlap length.
