A scanner includes a reading unit that reads an image of a paper, a medium feeding portion that is capable of selecting a first feeding mode in which a separation feeding for separately feeding a paper bundle in which a plurality of sheets of paper is overlapped with each other is performed and a second feeding mode in which a non-separation feeding for collectively feeding the paper bundle without separating is performed, and a pair of first transporting rollers and a pair of second transporting rollers that transport the paper fed by the medium feeding portion, in a case in which the medium feeding portion feeds the paper in the second feeding mode, a first driven roller and a second driven roller respectively constituting the pair of first transporting rollers and the pair of second transporting rollers are driven in a rotation direction where the paper is transported.

A printer includes an apparatus body having a recording head for performing recording onto a sheet of paper. The printer also includes a unit body that is accommodated inside the apparatus body and has a path-forming surface formed at least on a portion of the periphery of the unit body. The path-forming surface forms a medium transport path. The unit body includes a plurality of openings that are in communication with a sound absorber disposed inside the unit body. The plurality of the openings are provided at least on a portion of the path-forming surface.

A sheet conveying apparatus includes: a first pair of conveying rollers for conveying a sheet; a second pair of conveying rollers against which the leading edge of the sheet conveyed by the first pair of conveying rollers is hit and which conveys the sheet together with the first pair of conveying rollers by rotating after a loop is formed on the sheet; a separating portion for separating the first pair of conveying rollers; a first conveyance path for guiding the sheet; a second conveyance path which is a path different from the first conveyance path and guides the sheet; and a controller which changes a separation timing at which the first pair of conveying rollers is separated after the loop is formed on the sheet, depending on whether the sheet is guided by the first conveyance path or by the second conveyance path.

Disclosed is a sheet conveying apparatus, including: a conveying member configured to convey a sheet; a plurality of changing portions successively provided downstream of the conveying member in a conveying direction of the sheet, the plurality of changing portions being configured to change the conveying direction of the sheet conveyed by the conveying member by curving the sheet; and a control portion configured to control a conveying speed of the sheet. The control portion controls a conveying speed of the sheet such that V1<V2 where V1 indicates a conveying speed of a sheet conveyed by the conveying member, a leading end of which sheet passes through a specific changing portion among the plurality of changing portions, and V2 indicates a conveying speed of a sheet conveyed without passing through the specific changing portion.

In one example, a bail system for a sheet media tray includes a bail to apply a force to a sheet in the tray, a bias mechanism to counter the force of the bail on the sheet, and a control mechanism to control the degree to which the bias mechanism counters the force of the bail on the sheet.

An optical scanning device includes a reflected-light passing unit having a passing region through which a portion of reflected light that is the scanning light reflected by the medium passes. An outer peripheral contour line of the passing region includes a contour curve configured with a set of points where coordinates in a direction orthogonal to a scanning direction are uniquely determined for the coordinates in the scanning direction. The contour curve renders a curve protruded toward the passing region. When a region in contact with the contour curve in the passing region is divided into a plurality of quadrilateral minute regions having equivalent areas and extending from the contour curve to a predetermined coordinate position in the scanning direction and are continuously arranged in the orthogonal direction, widths of the minute regions in the scanning direction are different for each location in the orthogonal direction.
