Abstract: In a printing apparatus, a control unit stops paper feeding driven by a driving unit for driving a paper feeding roller in response to a timing at which a printing medium reaches a conveying roller, if the printing medium has a first size, and stops paper feeding driven by the driving unit before a detection unit located upstream of the conveying roller detects the printing medium if the printing medium has a second size smaller than the first size.

Abstract: The document conveying apparatus includes a separation roller, a conveying roller, a driving force generation module configured to be capable of generating a first driving force with a rotation in a first direction, and capable of generating a second driving force with a rotation in a second direction opposite to the first direction, a driving force transmission module, a determination module for determining whether a document has passed the separation roller, and a control module for switching a driving force from the first driving force to the second driving force in accordance with a determination result. The driving force transmission module performs separation operation by transmitting the first driving force to the separation roller, and conveys the documents by transmitting the second driving force to the conveying roller and cuts off transmission of the second driving force to the separation roller, in accordance with the switching.

Abstract: A document feeder includes a feed roller provided in a feed path for a document, a conveying roller provided on a downstream side of the feed roller in the feed path, and a protruding portion provided between the feed roller and the conveying roller in the feed path and protruding from a lower side of the feed path.

Abstract: A sheet feeding portion is provided with a pair of separation rollers that include a feed roller which conveys the sent sheet and a retard roller which applies a rotation force to return the sheet in a direction opposite to a sheet feeding direction through a torque limiter in a state of being pressed against the feed roller. The sheet feeding portion further includes a rotation transmitting mechanism that transmits a rotation of the retard roller, at the time of sending the sheet to the sheet feeding direction, to the pickup roller and a changing mechanism that switches a retard pressure, which allows the retard roller to be pressed against the feed roller, according to a reaction force that is transmitted to the retard roller from the pickup roller.

Abstract: An inkjet printing system comprising a media input support and a pivotable pick arm assembly including a pick roller. The assembly is biased to pivot toward the media input support. A rotatable arm is linked to the pivotable pick arm assembly and includes a ramped feature. The printing system further includes a carriage that includes a sloped feature that is in line with the ramped feature of the rotatable arm. When the sloped feature of the carriage is engages with the ramped feature of the rotatable arm the pick arm assembly is pivoted in a direction away from the media input support.

Abstract: A sheet feeding apparatus including: a separation claw for restraining both end portions of leading edges of sheets in a width direction orthogonal to a sheet feeding direction, the sheets having reached a sheet feeding position, and separating, one by one, the sheets fed by a pickup roller; and a photosensor detecting that the separation claw has reached a separation position for separating the sheets when a sheet stacking board is raised to detect that the sheets have reached the sheet feeding position, in which the separation claw, which is movable in an up-and-down direction, is moved to the separation position, the photosensor detects that the sheets supported by the sheet stacking board have reached the sheet feeding position of being feedable by the pickup roller, by rise of the sheet stacking board.

Abstract: A feed device feeds a sheet of a recording medium, and includes a body, a support shaft, and a pickup mechanism. The pickup mechanism contacts and picks up the sheet, and includes a swingable arm and a pickup unit. The swingable arm is rotatably mounted on a support shaft provided in the body of the feed device, and includes a fulcrum shaft. The pickup unit is rotatably attached to the fulcrum shaft of the swingable arm, and includes an endless elastic belt, a first pulley, a supporter, and a second pulley.

Abstract: Provided is a sheet conveying apparatus including: a first sheet conveying rotary member; a second sheet conveying rotary member provided upstream of the first sheet conveying rotary member; and a third sheet conveying rotary member provided upstream of the second sheet conveying rotary member, in which: the first sheet conveying rotary member, the second sheet conveying rotary member, and the third sheet conveying rotary member can convey the same sheet at the same time; a relationship between a peripheral speed V1 of the first sheet conveying rotary member, a peripheral speed V2 of the second sheet conveying rotary member, and a peripheral speed V3 of the third sheet conveying rotary member is V3>V1>V2; and a velocity of a sheet at a portion where the sheet is ejected from the second sheet conveying rotary member is equal to or lower than the peripheral speed of the first sheet conveying rotary member.

Abstract: A system for removing an interleaf sheet contacting a plate sheet used in an imaging system, comprised of a substantially horizontal member; an assembly comprising at least two elements configured to directly contact and pick up the interleaf sheet, a portion of said assembly connected to said member; a motor configured to move said member in a direction substantially perpendicular to a surface of the interleaf sheet as positioned prior to contact; and a first sensor system that generates a signal indicating when said member is a first predetermined distance from the interleaf sheet; and a second sensor system comprised of a second sensor that generates a signal indicating that the sheet beneath the second sensor is an interleaf sheet; said motor utilizing the first predetermined distance to move said member a second predetermined distance from the interleaf sheet, the at least two elements not contacting each other at the second predetermined distance, said motor moving said member in a direction toward the
