Abstract
A sheet-stapling apparatus mounts a center-fold booklet and staples the booklet at a fold of the booklet by a staple. The sheet-stapling apparatus has a supporting member that mounts the center-fold booklet, pushing members that push the booklet to the supporting member, a stapler that penetrates the staple through the booklet and a clincher that clinches legs of the staple to bind the booklet. Each pushing member has a pushing recess portion for pushing the fold of the booklet. The pushing recess portion spreads from a booklet-positioning angle to a booklet-pushing angle to prevent the booklet from shifting.
Claims6
A sheet-stapling apparatus that mounts a center-fold booklet and staples the booklet at a fold of the booklet by a staple, the apparatus comprising:
- a stapler that penetrates the staple into the booklet;
- a clincher that clinches legs of the staple penetrated into the booklet;
- and
- a booklet-holding member that holds the mounted center-fold booklet before the stapler penetrates the staple into the booklet, wherein the booklet-holding member includes a pushing recess portion that is configured to be composed of at least two pushing surfaces and to have a triangular section, a vertex of the triangular section aligning the fold of the booklet, and
- the pushing recess portion is configured to change an angle of the vertex of the triangular section from a booklet-positioning angle to a booklet-pushing angle by an action of the booklet-holding member so that a fold of the mounted booklet spreads out while the booklet-holding member pushes the mounted booklet after the mounted booklet is positioned at the booklet-positioning angle.
An image-forming system comprising an image forming apparatus that form an image on a sheet and a sheet-stapling apparatus that mounts a center-fold booklet including the sheet and staples the booklet at a fold of the booklet by a staple, the sheet-stapling apparatus including:
- a stapler that penetrates the staple into the booklet;
- a clincher that clinches legs of the staple penetrated into the booklet;
- and
- a booklet-holding member that holds the mounted center-fold booklet before the stapler penetrates the staple into the booklet, wherein the booklet-holding member includes a pushing recess portion that is configured to be composed of at least two pushing surfaces and to have a triangular section, a vertex of the triangular section aligning the fold of the booklet, and
- the pushing recess portion is configured to change an angle of the vertex of the triangular section from a booklet-positioning angle to a booklet-pushing angle by an action of the booklet-holding member so that a fold of the mounted booklet spreads out while the booklet-holding member pushes the mounted booklet after the mounted booklet is positioned at the booklet-positioning angle.
