Abstract
A sheet processing apparatus comprising a sheet stacking member for stacking a sheet to be discharged, and an offset mounting member for offsetting a plurality of sheet bundles on sides in a sheet bundle takeout direction and in a direction opposite thereto, and mounting the offset bundles onto the sheet stacking member. The offset mounting member mounts the first sheet bundle on the side in the sheet bundle takeout direction. When there is a sheet bundle on the sheet stacking member, the first sheet bundle is mounted by offsetting the first sheet bundle in a direction opposite to that of the last sheet bundle mounted.
Claims13
A sheet processing apparatus, comprising:
- sheet stacking means for stacking a sheet to be discharged;
- and
- offset mounting means for offsetting a plurality of sheet bundles on sides in a sheet bundle takeout direction and in a direction opposite thereto, and mounting the offset bundles onto said sheet stacking means,
- wherein said offset mounting means mounts a first sheet bundle on a side in the sheet bundle takeout direction;
- wherein said offset mounting means includes shifting means for shifting a sheet in a direction crossing a sheet discharging direction, and the sheet bundles are offset through control by said shifting means;
- wherein said offset mounting means is disposed on an upstream side of said sheet stacking means, and further comprises conveying means for conveying the sheet bundles to said sheet stacking means;
- wherein said offset mounting means further comprises a sheet stacking base onto which sheets re temporarily stacked, and second conveying means for conveying image-formed sheets to said sheet stacking base, and said shifting means serves also as aligning means for conducting width-direction alignment of sheets on said sheet stacking base for each run of conveyance by said second conveying means.
An image forming apparatus, comprising:
- sheet stacking means for stacking a sheet to be discharged;
- and
- offset mounting means for offsetting a plurality of sheet bundles on sides in a sheet bundle takeout direction and in a direction opposite thereto, and mounting the offset bundles onto said sheet stacking means,
- wherein said sheet stacking means and said offset mounting means are disposed in a space between an upper surface of a main body of said image forming apparatus and a reader disposed above said main body, and offset and mount sheets discharged from said main body;
- wherein said offset mounting means further comprises a sheet stacking base onto which sheets are temporarily stacked, and second conveying means for conveying image-formed sheets to said sheet stacking base, and said shifting means serves also as aligning means for conducting width-direction alignment of sheets on said sheet stacking base for each run of conveyance by said second conveying means.
