Abstract

A binding apparatus includes a binding tool, a binding tool driver, a shaft, and control circuitry. The binding tool is configured to execute a first binding process at a first binding position on a sheet bundle and execute a second binding process at a second binding position different from the first binding position on the sheet bundle. The binding tool driver includes a driver and is configured to apply a driving force to move the binding tool and a driving force to execute the first binding process and the second binding process. The shaft is disposed between the binding tool and the binding tool driver to support a movement of the binding tool by application of the driving force to the first binding position and the second binding position.

First claim

What is claimed is:

1. A binding apparatus comprising:
a binding tool configured to execute a first binding process at a first binding position on a sheet bundle and configured to execute a second binding process at a second binding position, different from the first binding position, on the sheet bundle;
a binding tool driver, configured to apply both a driving force to move the binding tool to the first binding position and to the second binding position, and a driving force to execute the first binding process and the second binding process; and
a main shaft, disposed between the binding tool and the binding tool driver, to support movement of the binding tool to the first binding position and to the second binding position by application of the driving force to move the binding tool.

2. The binding apparatus of claim 1 , further comprising:
a support shaft, configured to support the binding tool when the binding tool moves along the main shaft.

3. The binding apparatus of claim 2 ,
wherein the binding tool is disposed between the main shaft and the support shaft, in a horizontal direction.

4. The binding apparatus of claim 1 ,
wherein the binding tool driver includes a transmitter, configured to transmit the driving force.

5. The binding apparatus of claim 1 ,
wherein the binding tool driver includes a switching assembly, configured to switch between applying the driving force to the binding tool to execute the first binding process or to execute the second binding process, and applying the driving force to the binding tool driver to move the binding tool to the first binding position and to the second binding position.

6. The binding apparatus of claim 1 , further comprising
control circuitry configured to cause the binding tool to:
move the first binding position relatively lower than a position at which the binding tool is located before the first binding process begins;
execute the first binding process;
move the second binding position relatively higher than the position at which the binding tool is located before the first binding process begins; and
execute the second binding process.

7. An image forming apparatus comprising:
an image forming section configured to form an image on a sheet-like medium;
a conveyor configured to convey the sheet-like medium on which the image is formed in the image forming section; and
a post-processing apparatus, including the binding apparatus of claim 1 ,
the post-processing apparatus being configured to stack, align, and bind sheet-like media, including the sheet-like medium conveyed by the conveyance unit.

8. An image forming system comprising:
an image forming apparatus configured to form an image on a sheet-like medium;
a post-processing apparatus, including a binding apparatus to bind a sheet bundle including the sheet-like medium on which the image is formed in the image forming apparatus,
the binding apparatus including:
a binding tool, configured to execute a first binding process at a first binding position on a sheet bundle and configured to execute a second binding process at a second binding position, different from the first binding position, on the sheet bundle;
a binding tool driver, configured to apply both a driving force to move the binding tool to the first binding position and to the second binding position, and a driving force to execute the first binding process and the second binding process; and
a main shaft, disposed between the binding tool and the binding tool driver, and configured to support movement of the binding tool to the first binding position and to the second binding position by application of the driving force to move the binding tool.

9. The image forming system of claim 8 , wherein the binding apparatus further includes:
a support shaft, configured to support the binding tool when the binding tool moves along the main shaft.

10. The image forming system of claim 9 ,
wherein the binding tool is disposed between the main shaft and the support shaft, in a horizontal direction.

11. The image forming system of claim 8 , wherein the binding tool driver includes a transmitter, configured to transmit the driving force.

12. The image forming system of claim 8 ,
wherein the binding tool driver includes a switching assembly, configured to switch between applying the driving force to the binding tool to execute the first binding process or to execute the second binding process, and applying the driving force to the binding tool driver to move the binding tool from the first binding position to the second binding position.

13. The image forming system of claim 8 , wherein binding apparatus further includes
control circuitry configured to cause the binding tool to:
move the first binding position relatively lower than a position at which the binding tool is located before the first binding process begins;
execute the first binding process;
move the second binding position relatively higher than the position at which the binding tool is located before the first binding process begins; and
execute the second binding process.
