## Abstract

A sheet post-processing apparatus includes a binding unit that crimps a predetermined position on a sheet for binding, and a setting unit that sets the number of binding points at which to bind the sheet. The binding unit applies binding to the sheet at different positions as many as the number of binding points set by the setting unit.

## Claims

### Claim 1

A sheet post-processing apparatus comprising:
a binding part that crimps a predetermined position on a sheet for binding; and
a setting unit that sets the number of binding points at which to bind the sheet,
wherein if the number of binding points set by the setting unit is more than one, the binding part applies binding to a plurality of binding points along a predetermined direction, and
the setting unit obtains information about fastening force of the sheet, and sets the number of binding points based on the information about the fastening force.

### Claim 2 (depends on 1)

The sheet post-processing apparatus according to claim 1, wherein the binding part applies binding to different positions depending on the number of binding points of the sheet, set by the setting unit.

### Claim 3 (depends on 1)

The sheet post-processing apparatus according to claim 1, wherein if the number of binding points of the sheet, set by the setting unit is more than one, the binding part applies binding at different intervals depending on the number of binding points.

### Claim 4 (depends on 1)

The sheet post-processing apparatus according to claim 1, wherein if the number of binding points of the sheet, set by the setting unit is more than one, the binding part applies binding at a constant interval.

### Claim 5

A sheet post-processing apparatus comprising:
a binding part that binds a sheet by crimping;
a first setting unit that sets the number of binding points at which to bind the sheet;
a second setting unit that sets a binding position or positions on the sheet based on the number of binding points set by the first setting unit; and
a control unit that controls the binding part to apply binding to the binding position(s) set by the second setting unit,
wherein if the number of binding points set by the first setting unit is more than one, the second setting unit sets a plurality of binding positions along a predetermined direction, and the control unit controls the binding part to apply binding to the plurality of binding positions along the predetermined direction, and
the second setting unit, in oblique binding processing in which binding is applied to a corner of two sides of the sheet in a direction crossing the two sides, sets the plurality of binding points in a direction toward a center of the sheet, and in parallel binding processing in which binding is applied along one side of the sheet, sets the plurality of binding positions in a direction along the one side of the sheet.

### Claim 6

A sheet post-processing apparatus comprising:
a binding part that binds a sheet by crimping;
a first setting unit that sets the number of binding points at which to bind the sheet;
a second setting unit that sets a binding position or positions on the sheet based on the number of binding points set by the first setting unit; and
a control unit that controls the binding part to apply binding to the binding position(s) set by the second setting unit,
wherein if the number of binding points set by the first setting unit is more than one, the second setting unit sets a plurality of binding positions along a predetermined direction, and the control unit controls the binding part to apply binding to the plurality of binding positions along the predetermined direction;
the sheet post-processing apparatus has a corner binding mode in which binding processing is applied to a corner of two sides of the sheet, and a two-point binding mode in which the binding processing is applied to two points along one side of the sheet; and
the second setting unit, in the corner binding mode, sets the plurality of binding positions in a direction toward a center of the sheet, and in the two-point binding mode, sets the plurality of binding positions in a direction along one side of the sheet.

### Claim 7

A sheet post-processing apparatus comprising:
a binding part that binds a sheet by crimping;
a first setting unit that sets the number of binding points at which to bind the sheet;
a second setting unit that sets a binding position or positions on the sheet based on the number of binding points set by the first setting unit; and
a control unit that controls the binding part to apply binding to the binding position(s) set by the second setting unit,
wherein if the number of binding points set by the first setting unit is more than one, the second setting unit sets a plurality of binding positions along a predetermined direction, and the control unit controls the binding part to apply binding to the plurality of binding positions along the predetermined direction, and
if at least one binding position set by the second setting unit lies outside a predetermined binding region, the control unit stops a binding operation of the binding part.

### Claim 8

A sheet post-processing apparatus comprising:
a binding part that binds a sheet by crimping;
a first setting unit that sets the number of binding points at which to bind the sheet;
a second setting unit that sets a binding position or positions on the sheet based on the number of binding points set by the first setting unit; and
a control unit that controls the binding part to apply binding to the binding position(s) set by the second setting unit,
wherein if the number of binding points set by the first setting unit is more than one, the second setting unit sets a plurality of binding positions along a predetermined direction, and the control unit controls the binding part to apply binding to the plurality of binding positions along the predetermined direction, and
if binding traces in at least two binding positions set by the second setting unit overlap, the control unit stops a binding operation of the binding part.

### Claim 9

An image forming system comprising:
an image forming unit that forms an image on a sheet;
a processing tray that performs post-processing on the sheet on which the image is formed by the image forming unit;
a binding part that binds the sheet on the processing tray by crimping;
an operation unit that inputs processing information for performing the post-processing on the sheet;
a first setting unit that sets the number of binding points of the sheet based on the processing information input by the operation unit;
a second setting unit that sets a binding position or positions of the sheet based on the number of binding points set by the first setting unit; and
a control unit that controls the binding part to apply binding to the binding position(s) set by the second setting unit,
wherein if the number of binding points set by the first setting unit is more than one, the second setting unit sets a plurality of binding positions along a predetermined direction, and the control unit controls the binding part to apply binding to the plurality of binding positions along the predetermined direction, and
the processing information input by the operation unit includes at least information about fastening force of the sheet.

### Claim 10 (depends on 9)

The image forming system according to claim 9, further comprising:
a positioning unit that positions the sheet to a predetermined position on the tray; and
a moving unit that moves the binding part along one side of the positioned sheet,
wherein the control unit controls the moving unit and the binding part to apply binding to a plurality of binding positions.
