发明名称 Sheet conveyer and image forming apparatus
摘要 A sheet conveyer including a body, a conveyer to convey the sheet into a conveyer path formed in the body, a conveyer-supporting frame to support the conveyer, a first placement unit including a lifting plate movable between a separated position and an approximate position, and a lateral guide arranged on the lifting plate to be movable integrally with the lifting plate and slidably along a widthwise direction and configured to restrict a widthwise position of the sheet placed on the lifting plate and, is provided. The conveyer contacts the sheet placed on the first placement unit, when the lifting plate is in the approximate position, and conveys the contacting sheet into the conveyer path. The conveyer-supporting frame is formed to have an interference-avoidable dented section, in which the side guide on the lifting plate placed in the approximate position enters partly to avoid interference with the conveyer-supporting frame.

主权项 1. A sheet conveyer, comprising: a body comprising a conveyer path formed therein; a conveyer arranged in an upstream position in the conveyer path along a direction of sheet conveyance in the body and configured to convey a sheet into the conveyer path; a first lateral frame disposed inside the body; a second lateral frame disposed inside the body; a conveyer-supporting frame arranged between the first lateral frame and the second lateral frame in the body and configured to support the conveyer between the first lateral frame and the second lateral frame in the body, the conveyer-supporting frame extending longitudinally in a widthwise direction transverse to the direction of sheet conveyance in the body and including a first longitudinal end connected to the first lateral frame and a second longitudinal end connected to the second lateral frame; a first placement unit arranged between the first lateral frame and the second lateral frame in the body and comprising a lifting plate, the lifting plate being movable between a separated position, in which the lifting plate is separated downwardly from the conveyer, and an approximate position, in which the lifting plate is uplifted to be closer to the conveyer, the sheet to be conveyed into the conveyer path being placed on the lifting plate; and a lateral guide slidably arranged on the lifting plate along the widthwise direction transverse to the direction of sheet conveyance in the body and configured to restrict a widthwise position of the sheet placed on the lifting plate, the lateral guide being movable integrally with the lifting plate between the separated position and the approximate position, wherein the conveyer is configured to contact the sheet placed on the first placement unit, when the lifting plate is in the approximate position and convey the sheet into the conveyer path, and wherein the conveyer-supporting frame is formed to have an interference-avoidable dented section, in which the lateral guide on the lifting plate placed in the approximate position is allowed to enter partly to avoid interference with the conveyer-supporting frame; the sheet conveyor further comprising: a second placement unit arranged in an upper position with respect to the first placement unit in the body and on which a second sheet to be conveyed into the conveyer path is placed, wherein the conveyer is configured to contact the second sheet placed on the second placement unit, when the lifting plate is in the approximate position, and convey the second sheet into the conveying path; wherein the lateral guide is movable along the widthwise direction of the sheet within a first range; wherein the second placement unit comprises a second lateral guide, which is arranged on the second placement unit slidably along a widthwise direction of the second sheet placed on the second placement unit and is configured to restrict a widthwise position of the second sheet on the second placement unit; wherein the second lateral guide is movable along the widthwise direction of the second sheet within a second range; and wherein the second range, within which the second lateral guide is movable, is larger than the first range, within which the lateral guide is movable.
