Abstract

In accordance with one embodiment, a sheet binding apparatus comprises a pasting section and a control section. The pasting section is capable of selectively carrying out pasting processing on at least one of a plurality of different given pasting target areas on sheets to be pasted. The control section controls the execution of the pasting processing based on the pasting section so that pasting target areas of a first sheet and a second sheet other than the first sheet within a plurality of sheets to be subjected to binding processing are different.

First claim

What is claimed is:

1. A sheet binding apparatus for binding a sheet bundle with adhesive, comprising:
a first reel;
a second reel;
a tape, of which one end is wound on the first reel and the other end is wound on the second reel, configured to carry, on a base tape, adhesive that is peeled off from the base tape and coated on a target sheet if being pressed against the target sheet;
a rotation driving mechanism configured to rotate the first reel and the second reel in a first rotation direction to wind the tape fed from the first reel on the second reel;
a pressing mechanism, which is positioned at the side of the tape which does not face the target sheet, configured to press a given area of the tape facing the target sheet against the target sheet; and
a controller configured to acquire information indicating whether the sheet to be pressed by the pressing mechanism is a sheet to be subjected to adhesive coating processing or a sheet to be merely subjected to pressing processing instead of the adhesive coating processing, the controller configured to control, based on the information acquired, the pressing mechanism to press the sheet to be subjected to the adhesive coating processing in a state in which the part of the tape where the adhesive is carried is fed to a given area, and to press the sheet to be merely subjected to pressing processing instead of the adhesive coating processing in a state in which the part of the tape where the adhesive is carried is not fed to the given area by rotating the first reel in a second direction opposite to the first rotation direction to wind the tape fed from the second reel on the first reel by the rotation driving mechanism; wherein
the sheet to be merely subjected to pressing processing instead of the adhesive coating processing is a sheet onto which a next sheet supposed to be overlapped on the sheet surface scheduled to be subjected to adhesive coating processing is not fed.

2. The sheet binding apparatus according to claim 1 , wherein
the sheet to be merely subjected to pressing processing instead of the adhesive coating processing is a sheet equivalent to the front cover of the sheet bundle to be bound.

3. The sheet binding apparatus according to claim 1 , wherein
the next sheet is not fed by jamming the next sheet.

4. The sheet binding apparatus according to claim 1 , wherein
the rotation driving mechanism is a motor.

5. A sheet binding apparatus for binding a sheet bundle with adhesive, comprising:
a first reel;
a second reel;
a tape, of which one end is wound on the first reel and the other end is wound on the second reel, configured to carry, on a base tape, adhesive that is peeled off from the base tape and coated on a target sheet if being pressed against the target sheet;
a rotation driving mechanism configured to rotate the first reel and the second reel in either of a first driving mode in which the first reel and the second reel are rotated in a first rotation direction to wind the tape fed from the first reel on the second reel and a second driving mode in which the first reel and the second reel are rotated in a second rotation direction opposite to the first rotation direction to wind the tape fed from the second reel on the first reel;
a pressing mechanism, which is positioned at the side of the tape which does not face the target sheet, configured to press a given area of the tape facing the target sheet against the target sheet; and
a controller configured to acquire information indicating whether the sheet to be pressed by the pressing mechanism is a sheet to be subjected to adhesive coating processing or a sheet to be merely subjected to pressing processing instead of the adhesive coating processing, the controller configured to control, based on the information acquired, the pressing mechanism to press the sheet to be subjected to adhesive coating processing in a state in which the part of the tape where the adhesive is carried is fed to the given area through the first driving mode, and to press the sheet to be merely subjected to pressing processing instead of the adhesive coating processing in a state in which the part of the tape where no adhesive is carried is fed to the given area through the second driving mode; wherein
the sheet to be merely subjected to pressing processing instead of the adhesive coating processing is a sheet onto which a next sheet supposed to be overlapped on the sheet surface scheduled to be subjected to adhesive coating processing is not fed.

6. The sheet binding apparatus according to claim 5 , wherein
the sheet to be merely subjected to pressing processing instead of the adhesive coating processing is a sheet equivalent to the front cover of the sheet bundle to be bound.

7. The sheet binding apparatus according to claim 5 , wherein
the next sheet is not fed by jamming the next sheet.

8. The sheet binding apparatus according to claim 5 , wherein
the rotation driving mechanism is a motor.
