It rotates together with the telescopic bar 263 by driving the motor in the support base 264.

The support 264 is supported by a rotating shaft 265 which is rotated by driving a rotating motor 266. Since the support 264 is engaged with the spiral groove of the rotation shaft 265, when the rotation shaft 265 is rotated by the driving of the rotation motor 266, the support 264 moves in the X direction which is a direction orthogonal to the transfer direction of the transfer material. . The amount of movement of the support 265 is determined by the number of rotations and the direction of rotation of the rotation motor 266.

The lower rotating disk 262 (not shown) is also formed by the same member as the upper rotating disk 261 described above.

(C) shows the movement of the horizontally conveyed transfer material when horizontal binding is specified, and (D) shows the transfer of the vertically conveyed transfer material when horizontal binding is specified. It is explanatory drawing of movement of a material.

The binding position when binding a booklet is as follows:
When the transfer material has the size of A4 size, it is designated as vertical binding which binds the long side surface and horizontal binding which binds the short side surface. Alternatively, for the image formed on the transfer material,

The transfer state of the transfer material after the transfer, d indicates the transfer state of the transfer material having the end portion L coated with the glue by the glue discharging means 41. The transfer material is transported in the order of a to d. In order to explain the movement of the transfer material, a transfer reference line M parallel to the transfer direction and a gluing position of the glue discharging unit 41 are represented by a reference line L.

In the case of (A), when the vertical binding is designated by the information on the binding position, it is determined from the information on the transport direction that the transferred transfer material cannot be glued by the gluing means 40 for the vertical binding. Move the transfer material clockwise by 9
By rotating the transfer material by 0 degrees, the transfer of the transfer material is changed from the horizontal transfer to the vertical transfer, and the transfer material can be glued by vertical binding. Further, since the transfer material deviates from the reference line N due to the rotational movement, the transfer material is moved to the gluing position by performing the one-sided processing. Here, the image formed on the transfer material is glued to the vertical binding position on the left side, but when the designated vertical binding is on the right side of the image, the rotating unit 26 moves the transfer material counterclockwise. 90 ° rotation or clockwise 27 degrees
It may be rotated by 0 degrees.

In (B), when the vertical binding is designated by the information of the binding position, it is determined from the information of the transport direction that the transferred transfer material can be glued by the gluing means 40 for the vertical binding. Do not perform rotational movement due to. However, since the transfer material is displaced from the reference line N, the rotation means 2
6, the transfer material is moved by performing the one-sided processing.

(C), when the horizontal binding is designated by the information on the binding position, it is determined from the information on the transport direction that the conveyed transfer material can be pasted by the pasting means 40, so that the rotating means 26 Do not perform rotational movement due to. Further, since the transfer material does not deviate from the reference line N, the offset processing is not performed.

In (D), when the horizontal binding is designated by the information on the binding position, it is determined that the transfer material conveyed cannot be pasted by the pasting means 40 by the pasting means 40 from the information on the conveying direction. 26, the transfer material is rotated by 90 degrees to change the transfer of the transfer material from the horizontal conveyance to the vertical conveyance, so that gluing can be performed by vertical binding. Further, when the binding position from the end of the transfer material is specified by the information on the binding position, the transfer material is moved to the specified position by performing the one-side alignment process.

That is, in order to glue the end of the transfer material by the gluing means 40, the transfer material is moved based on the information on the binding position and the information on the transport direction, and the transfer material transported in an arbitrary transport direction is performed. Is glued to the binding position specified at an arbitrary position.

FIG. 4 shows the holding means 20 for moving the transfer material.

Information on the binding position and information on the transport direction are obtained from the image forming apparatus A (101). In order for the gluing means to glue, a determination is made to move the transfer material based on the information on the binding position and the information on the transport direction, and the amount of movement is calculated (104). When the transfer direction of the transferred transfer material is changed according to the calculated movement amount (105), the transfer material is rotated and moved by controlling the holding means (106).

Further, when the position of the edge of the transfer material is changed in accordance with the calculated movement amount (107), the holding means is controlled to perform the offset processing (108). Then, the glue is controlled to apply glue to the conveyed transfer material (10

The transported transfer material P is transported in the S direction by the thin film forming roller 43, and the transfer material P is detected by the transport detection sensor 42 and glued.

In order to apply the glue to the designated binding position, the control unit 100 acquires information on the binding position and information on the transport direction. On the basis of the acquired information on the binding position and the information on the transport direction, the glue discharging unit 41 is moved by the moving member T from the opening OP provided on the transport path to glue the transfer material P.

More specifically, when the transfer direction of the transfer material and the binding position are parallel, the glue discharging unit 41 is moved in the X direction to the designated binding position before the transfer material P is transported to the glue discharging unit 41. It is moved to apply glue according to the transferred transfer material.

When the transfer direction of the transfer material is orthogonal to the binding position, the transfer of the transfer material P is stopped at the opening OP, and the glue discharging means 41 is moved in the Y direction to be positioned at the leading end of the binding position. Next, the glue is applied to the designated binding position while moving the glue discharging means 41 in the X direction.

In the first embodiment, since the placed transfer material is glued to a predetermined position in the first embodiment, the alignment pressing means 50 presses the predetermined position. However, in the second embodiment, since the stapling position of the placed transfer material differs depending on the direction in which the transfer material is conveyed, the roller width of the pressure roller member 56 is made equal to the full width of the transfer material, and the full width of the transfer material is increased. I'm pressing.

In the first embodiment and the second embodiment, the binding information is transmitted from the image forming apparatus A to the post-processing apparatus C.
However, the post-processing device C may be provided with an input means so that the operator can directly input to the post-processing device C.

In the first and second embodiments, the post-processing device C receives and acquires information on the transfer direction of the transfer material from the image forming apparatus A. C conveyance detection means 21 or conveyance detection sensor 4
2 may be configured to have the same function as the conveyance direction detecting means 8 to detect and acquire the conveyance direction information.
