Abstract

Disclosed herein is a sheet binding apparatus that comprises a first binding unit provided and a second binding unit configured to perform needle binding on sheets, and a second binding unit configured to perform non-needle binding on sheets. A needle replenishing position where needles are replenished in the first binding unit is set in the vicinity of the second binding unit.

First claim

What is claimed is:

1. A sheet binding apparatus comprising:
a first binding unit provided to move along one side of each sheet and between both ends thereof, and configured to perform needle binding on the sheets,
a second binding unit provided at one end of the side of each sheet, and configured to perform non-needle binding on the sheets,
wherein a needle replenishing position where needles are replenished in the first binding unit is set at one end of each sheet located at the second binding unit, and
a first opening for allowing an access to the first binding unit is made in one side of the sheet binding apparatus, and a second opening for allowing an access to the second binding unit is made in a front of the sheet binding apparatus.

2. The sheet binding apparatus according to claim 1 , wherein the second binding unit is arranged in the front of the sheet binding apparatus.

3. The sheet binding apparatus according to claim 2 , wherein the needle replenishing position is set closer to the second binding unit than to a midpoint of a distance the first binding unit moves.

4. The sheet binding apparatus according to claim 2 , wherein a manual binding section having a sheet insertion hole is provided at the front of the sheet binding apparatus, and the second binding unit binds the sheets inserted through the sheet insertion hole into the manual binding section.

5. A sheet binding apparatus comprising:
a transporting section configured to transport sheets;
a processing tray configured to hold the sheets transported from the transporting section;
an aligning device configured to align two end portions of the sheets in a sheet width direction on the processing tray;
a first binding unit configured to perform needle binding on the sheets held on the processing tray;
a second binding unit arranged at one end of the processing tray in the sheet width direction and configured to perform non-needle binding on the sheets held on the processing tray;
a needle-replenishing position where needles are replenished in the first binding unit, the needle-replenishing position being located at the one end of the processing tray in the sheet width direction and adjacent to the second binding unit; and
a moving mechanism configured to move the first binding unit to the needle-replenishing position,
wherein the second binding unit binds sheets on the processing tray, at one end corner, and the first binding unit binds sheets on the processing tray, at the other end corner, and
the aligning device shifts the sheets to the one end of the processing tray so that the second binding unit binds the sheets, and to the other end of the processing tray so that the first binding unit binds the sheets.

6. The sheet binding apparatus according to claim 5 , wherein a front of the sheet binding apparatus has a first opening for accessing the second binding unit, and one side of the sheet binding apparatus has a second opening for accessing the first binding unit.

7. The sheet binding apparatus according to claim 5 , further comprising a manual binding section having an insertion hole and a support member for supporting the sheets inserted in the insertion hole, wherein the second binding unit performs binding on the sheets supported by the support member.

8. An image forming system configured to form an image on a sheet and to perform a post-processing on the sheet, comprising:
an image forming apparatus having an image forming section configured to form an image on a sheet, and a sheet ejecting section configured to eject the sheets coming from the image forming section; and
a sheet binding apparatus having a processing tray configured to hold sheets to be bound together; a sheet feeding section configured to receive the sheets from the sheet ejecting section of the image forming apparatus and to feed the sheets to the processing tray; a first binding unit capable of moving in a sheet width direction orthogonal to a direction of feeding the sheets and configured to perform needle binding on the sheets on the processing tray; a second binding unit provided at one side of the processing tray, as viewed in the sheet width direction, and configured to perform non-needle binding on the sheets; a moving mechanism configured to move the first binding unit to a prescribed position at said one side of the processing tray; a first opening made in said one side of the processing tray and exposing at least one part of the first binding unit moved to the prescribed position; and a second opening made in the one side of the processing tray and exposing at least one part of the second binding unit.

9. The image forming system according to claim 8 , wherein the first and second openings are made in different sides of the sheet binding apparatus.

10. The image forming system according to claim 8 , wherein the first opening is made in a side of the sheet binding apparatus, which opposes the sheet feeding section of the sheet binding apparatus, and a guide mechanism is provided to move the sheet binding apparatus away from the sheet feeding section.

11. The image forming system according to claim 8 , wherein a needle-replenishing position for replenishing the first binding unit with needles is set at one end of each sheet placed in the second binding unit.

12. The image forming system according to claim 8 , further comprising a selecting section configured to select the first binding unit or the second binding unit, wherein if the second binding unit is selected, the image forming section of the image forming apparatus forms images rotated by 180° with respect to the images the image forming section forms if the first binding unit is selected.
