摘要： A sheet feeder includes: a wheel for issuing a lowermost sheet out to a sheet processing unit; a grate for spacing the sheet apart from the wheel at a raised position and bringing the sheet into contact with the wheel at a lowered position; and a drive device for driving the grate up and down. The drive device includes: a link mechanism for movably supporting the grate; a spring for urging the grate to the lowered position; a grate raising/lowering cam for periodically driving the grate up/down; and a skip feed cam that is driven by a control device, separately from a drive system of the grate raising/lowering cam, and that, at a timing where reached is a phase at which the grate raising/lowering cam does not put the grate in the raised position, retains the grate at the raised position in order to skip feeding of the sheet.

摘要： In a sheet conveyor, a stopper piece of a sheet stopper temporarily stops a sheet supported on a sheet tray, and a pickup roller conveys the sheet from the sheet tray in a sheet conveying direction. A first sheet sensor disposed upstream of a registration roller and downstream of the stopper piece in the sheet conveying direction detects a leading edge of the sheet, and a second sheet sensor disposed downstream of the registration roller detects the leading edge of the sheet. A first contact member of the first sheet sensor receives the leading edge of the sheet. A second contact member of the second sheet sensor receives the leading edge of the sheet. The stopper piece, the first contact member, and the second contact member are offset from each other in a direction perpendicular to the sheet conveying direction and unaligned with each other in the sheet conveying direction.

摘要： A sheet conveying apparatus includes: a supporter having a support surface; a supplier including a supply roller rotatable about a rotation axis; a separator for separating sheets; a stopper pivotable about a first axis and movable between a first position at which a distal end portion of the stopper intersects a conveyance path and a second position at which the distal end portion is separated from the support surface; and a stopper cam pivotable about a second axis and movable between a third position at which the stopper cam contacts the distal end portion at the first position and a fourth position at which the stopper cam is spaced apart from the distal end portion at the first position. The second axis is located upstream of the rotation axis of the supply roller and farther from the support surface than the rotation axis.

摘要： A sheet feeding device comprising: a stacking member on which a sheet is stacked; a first conveying portion that conveys a sheet stacked on the stacking member; a second conveying portion that separates and conveys a sheet conveyed by the first conveying portion; a stopper member that stops a sheet whose front end is abutted against the stopper member at an upstream of the second conveying portion in a sheet conveying direction, wherein the stopper member can be at a first position where the sheet can be stopped and a second position where the sheet can pass the stopper member, and wherein the stopper member can move from the first position toward the second position such that a sheet conveyed by the first conveying portion reaches the second conveying portion while maintaining a state where the front end of the sheet is abutted to the stopper member.

摘要： A sheet feeder includes a sheet platen, a pickup roller, a feeding roller, a regulating portion, a driving mechanism, a feeding control unit, a sheet sensor, and a determination processing unit. The feeding control unit executes a feeding operation by rotationally driving the pickup roller and the feeding roller in a state where the regulating portion is located at a retreating position. The sheet sensor is located at a downstream side in the feeding direction of the feeding roller. The determination processing unit determines whether the sheet feeding has succeeded or not based on a signal from the sheet sensor. After a start of the feeding operation, when the determination processing unit determines that the sheet feeding has failed, the feeding control unit once moves the regulating portion located at the retreating position to the abutting position and then executes the feeding operation again.

摘要： A sheet conveyance apparatus is equipped with a stacking portion on which sheets are stacked, a rotator conveying a sheet by rotating in a contact state with the sheet stacked on the stacking portion, a separating member pressing the rotator and separating the sheets one by one at a contact portion where the rotator and the separating member contact each other, and a holder holding the separating member. A guide portion is rotatably provided with the holder and capable of guiding a front end of the sheet to the contact portion, and a regulating portion regulates the guide portion from rotating in a direction approximating the rotator in a state where the guide portion contacts against the regulating portion. The guide portion can be rotated in a direction separating from the rotator in a state where the separating member presses the rotator.

摘要： A paper feeder includes a housing, a driving unit, a sheet loading portion, a paper feeding unit, and a lock mechanism. The lock mechanism is located in the housing. The paper feeding unit includes a pickup roller, a second shaft portion, a feed roller, a holder, and a stopper. The stopper is swingably supported in the holder, and is configured to change states between a regulation state and a permission state. The regulation state is a state that regulates entrance of the sheet to be loaded in the sheet loading portion into a side of the feed roller side corresponding to the second position of the holder. The permission state is a state that permits entrance of the sheet into the feed roller side corresponding to the first position of the holder. The lock mechanism locks the holder in the second position at a time of non-paper feeding.
