Abstract
A sheet treating apparatus has a discharging device for discharging a sheet with an image formed thereon to a sheet stacking device, the stacking device having an abutment reference member disposed on the leading end side of the sheet stacking device and an urging member disposed on a sheet trailing end side of the sheet stacking device for urging the sheet discharged from the discharging device toward the abutment reference member.
Claims19
A sheet treating apparatus, comprising:
- discharging means for conveying and discharging a sheet on which an image is formed;
- sheet stacking means on which the sheet discharged by said discharging means is stacked;
- an abutment reference member disposed on a side of a sheet leading end in a direction in which the sheet is discharged from said discharging means onto said sheet stacking means, a leading end of the sheet discharged onto said sheet stacking means to be abutted against said abutment reference member;
- and
- an urging member disposed on a side of a sheet trailing end in the direction in which the sheet is discharged from said discharging means onto said sheet stacking means, for urging the sheet discharged from said discharging means toward said abutment reference member,
- wherein said urging member has an urging surface which is an inclined surface which inclines downward toward an abutment reference member side.

- an urging member disposed on a side of a sheet trailing end in the direction in which the sheet is discharged from said discharging means onto said sheet stacking means, for urging the sheet discharged from said discharging means towards said abutment reference member;
- and
- width aligning means for aligning the sheet in a sheet width direction perpendicular to a sheet conveying direction after the leading end of the sheet discharged from said discharging means onto said sheet stacking means abuts against said abutment reference member,
- wherein said width aligning means comprises plate members opposed to each other and disposed on both ends in the sheet width direction so that the plate members each abuts against an end of the sheet in the sheet width direction, both or one of said plate members moving in a direction in which the sheet is held, to align the sheet in the sheet width direction, and
- wherein said plate members each comprises on a surface thereto to abut against the end of the sheet a roller member rotatable in the sheet conveying direction and having a substantially conical shape on an opposite side of each of said plate members, and said roller member presses an upper side of the end of the sheet during a sheet aligning operation by said plate members.
