Abstract
A post-processing apparatus includes a conveyance unit configured to convey a sheet to which an adhesive has been applied, a support unit configured to support the conveyed sheet, a bonding unit movable relative to the support unit to bond a sheet bundle using the adhesive, and a control unit configured to control the conveyance unit and the bonding unit. The control unit operates in a first mode in which a subsequent sheet is stacked on a preceding sheet bundle while bonding processing is performed, and a second mode in which stacking is performed after completion of bonding processing. The second mode is selected when a condition indicating reduced post-processing performance is satisfied, and the first mode is otherwise selected.
Claims17
A post-processing apparatus comprising:
- a conveyance unit configured to convey a sheet to which an adhesive was applied;
- a support unit configured to accept and support the sheet conveyed by the conveyance unit;
- a bonding unit configured to move relative to the support unit and to bond, with the adhesive, a sheet bundle formed by a plurality of sheets and supported by the support unit;
- and
- a control unit configured to control the conveyance unit and the bonding unit and having a first mode in which, while the bonding unit is executing bonding processing on a preceding sheet bundle, a subsequent sheet is stacked on the preceding sheet bundle, and a second mode in which, after bonding processing performed on a preceding sheet bundle by the bonding unit is complete, a subsequent sheet is stacked on the preceding sheet bundle,
- wherein the second mode is selected in a case where a condition according to which post-processing performance of the subsequent sheet decreases relative to the preceding sheet bundle is satisfied, and the first mode is selected in a case where the condition is not satisfied.
An image forming apparatus comprising:
- an image forming unit configured to form an image on a sheet;
- an applying unit configured to apply an adhesive to the sheet;
- a conveyance unit configured to convey the sheet to which the adhesive was applied;
- a support unit configured to accept and support the sheet conveyed by the conveyance unit;
- a bonding unit configured to move relative to the support unit and to bond, with the adhesive, a sheet bundle formed by a plurality of sheets and supported by the support unit;
- and
- a control unit configured to control the conveyance unit and the bonding unit and having a first mode in which, while the bonding unit is executing bonding processing on a preceding sheet bundle, a subsequent sheet is stacked on the preceding sheet bundle, and a second mode in which, after bonding processing performed on a preceding sheet bundle by the bonding unit is complete, a subsequent sheet is stacked on the preceding sheet bundle,
- wherein the second mode is selected in a case where a condition according to which post-processing performance of the subsequent sheet decreases relative to the preceding sheet bundle is satisfied, and the first mode is selected in a case where the condition is not satisfied.
