Sheet ejection tray

摘要

A sheet ejection tray on which a sheet ejected from a sheet ejection port lands, includes: an inclined surface that becomes higher as farther from the sheet ejection port in a sheet ejecting direction; a projecting member that is provided in a region closer to the sheet ejection port than the position on which a leading end of the sheet having a dimension not smaller than a predetermined value lands and which has a guiding surface more inclined than the inclined surface; and an abutting cover that contacts a rear end of the sheet moving toward the sheet ejection port due to the inclination of the guiding surface. The leading end of the sheet passes above the projecting member before landing on the guiding surface. A portion of the sheet closer to the sheet ejection port than the leading end lands on the guiding surface.

主权项

1. A sheet ejection tray on which a sheet ejected from a sheet ejection port of an image forming apparatus lands and which guides the sheet to a stacking position, comprising:
a tray main body positioned to receive sheets in the stacking position; an inclined surface provided along a top of the tray main body,
wherein the sheets are ejected from the sheet ejection port and placed in the stacking position, andwherein a height of the inclined surface increases in accordance with an increase in distance from the sheet ejection port in an ejecting direction of the sheet; a projecting member provided on the inclined surface of the tray main body,
wherein the projecting member has a guiding surface, which is a whole side surface of the projecting member, with an inclination larger than an inclination of the inclined surface, andwherein the guiding surface has a predetermined inclination angle such that the guiding surface comprises a linear surface; an abutting cover positioned on a rear end portion of the tray main body in the sheet ejecting direction,
wherein the abutting cover is configured to be brought into contact with a rear end of the sheet moving toward the sheet ejection port due to the inclination of the guiding surface after the sheet lands on the guiding surface; and a pair of side fences are provided on the rear end portion of the tray main body on opposite sides in a sheet width direction, transverse to the ejecting direction, the side fences being configured to move relative to the tray main body in the sheet width direction,
wherein each of the side fences includes a rigidity-imparting member positioned at a rearmost end of each of the side fences,wherein a height of the rigidity imparting member relative to the tray main body in the sheet width direction decreases in accordance with an increase in distance from each of the side fences, andwherein the height of the rigidity-imparting member relative to the tray main body in the ejecting direction decreases in accordance with an increase in distance from the abutting cover.
