Abstract

A sheet processing apparatus includes a sheet holding unit, a sheet conveying unit configured to convey a plurality of sheets one by one onto the sheet holding unit during sheet processing, wherein the plurality of sheets including a first sheet and a second sheet that is conveyed immediately after the first sheet and is a last of the plurality of sheets that is conveyed, an adhesive applying unit configured to apply an adhesive material, and a control unit configured to control the adhesive material applying unit to apply the adhesive material on the first sheet held on the sheet holding unit before the second sheet is conveyed onto the first sheet and cause the adhesive material applying unit to not apply the adhesive material on the second sheet after the second sheet is conveyed onto the first sheet.

First claim

What is claimed is:

1. A sheet processing apparatus comprising:
a sheet holding unit;
a sheet conveying unit configured to convey a plurality of sheets one by one onto the sheet holding unit during sheet processing, the plurality of sheets including first sheets and a second sheet that is conveyed immediately after the first sheets;
an adhesive applying unit configured to apply an adhesive material on a sheet;
a control unit configured to control the adhesive material applying unit to apply the adhesive material on each of the first sheets held on the sheet holding unit before the second sheet is conveyed onto the first sheets; and
a sheet detecting unit configured to detect a sheet passing through a sheet conveyance path,
wherein the control unit is further configured to determine the second sheet to be a last of the plurality of sheets that is conveyed as a result of the sheet detecting unit not detecting a sheet for a period of time that is equal to or longer than a predetermined period of time, and cause the adhesive material applying unit to not apply the adhesive material on the second sheet after the second sheet is conveyed onto the first sheets.

2. A sheet processing apparatus comprising:
a sheet holding unit;
a sheet conveying unit configured to convey a plurality of sheets one by one onto the sheet holding unit during sheet processing, the plurality of sheets including first sheets and a second sheet that is conveyed immediately after the first sheets;
an adhesive applying unit configured to apply an adhesive material on a sheet; and
a control unit configured to control the adhesive material applying unit to apply the adhesive material on each of the first sheets held on the sheet holding unit before the second sheet is conveyed onto the first sheets, wherein
the control unit is further configured to receive information indicating that a sheet is going to be conveyed to the sheet conveying unit from an external device, and determine the second sheet to be a last of the plurality of sheets that is conveyed as a result of the information not being received, and cause the adhesive applying unit to not apply the adhesive material on the second sheet.

3. The sheet processing apparatus according to claim 2 , wherein
the control unit determines the second sheet to be the last of the plurality of the sheets as a result of the information not being received for a period of time that is equal to or longer than a predetermined period of time.

4. A method for sheet processing comprising:
conveying a plurality of sheets one by one onto a sheet holding unit and detecting the sheets during the conveying;
applying an adhesive material on each of the sheets except on a last of the sheets after said each sheet is conveyed onto the sheet holding unit; and
determining that the last of the sheets has been conveyed onto the sheet holding unit when another sheet is not detected for a period of time that is equal to or longer than a predetermined period of time after the last of the sheets has been detected.

5. The method for sheet processing according to claim 4 , wherein
the adhesive material is not applied on the last of the sheets responsive to determining that the last of the sheets has been conveyed.
