  The first processing unit 110 is an example of a unit that performs a predetermined process (hereinafter referred to as “medium processing”) on the first surface of the medium transported through the first transport path 11. In the present embodiment, the first processing unit 110 is installed on the preprocessing device 2 side of the first transport path 11, and the surface of the medium transported on the first transport path 11 is directed to the preprocessing device 2 side. As one surface, processing for reading an image formed on the first surface (hereinafter referred to as “image reading processing”) is performed as medium processing. In FIG. 2, a first processing position D1 where the image reading process is performed on the medium by the first processing unit 110 is illustrated. In the first processing position D1, the medium is transported in the first direction A10.

  The first related member 111 is an example of a member that is disposed at a position opposite to the first processing unit 110 with the first transport path 11 interposed therebetween, and that functions in relation to processing by the first processing unit 110. In the present embodiment, the first related member 111 is a prismatic member, and a test image representing a plurality of colors such as red and yellow is formed on the outer peripheral surface thereof.

Perform color correction. As described above, the first related member 111 serves to correct the color of the image read in the image reading process.

  The second processing unit 120 is an example of a unit that performs processing on the second surface opposite to the first surface of the medium that is being transported through the first transport path 11 or the second transport path 21. The second processing unit 120 is disposed at a position farther from the folding and conveying unit 30 side than the first processing unit 110. That is, the length from the first processing position D1 by the first processing unit 110 to the exit of the first transport path 11 (that is, the entrance C3 of the folded transport section 30) is L11, and the second from the entrance C4 of the second transport path 21 to the second When the length to the second processing position D2 by the processing unit 120 is L21, the second processing unit 120 is arranged so that L11 is shorter than L21 (that is, L11 <L21). Moreover, the 2nd process part 120 is installed in the pre-processing apparatus 2 side of the 2nd conveyance path 21, and makes the surface which faced the pre-processing apparatus 2 side of the medium currently conveyed in the 2nd conveyance path 21 into a 2nd surface. An image reading process is performed. FIG. 2 shows a second processing position D2 where the image reading process is performed on the medium by the second processing unit 120. At the second processing position D2, the medium is transported in the second direction A20.

  The second related member 121 is a member that is disposed at a position facing the second processing unit 120 across the transport path (second transport path 21 in the example of FIG. 2), and functions as processing by the second processing unit 120. It is an example. The second related member 121 functions in common with the first related member 111 with respect to processing by the second processing unit 120. As described above, since the related members corresponding to the first processing unit 110 and the second processing unit 120 are provided, the processing performed by each of the first processing unit 110 and the second processing unit 120.

[1-3] About the shape of the conveyance path In the present embodiment, each conveyance path is formed so that the conveyance path B1 is U-shaped, and the medium is conveyed in the height direction of the conveyance device on the straight portion of the U-shape. Is done. As a result, when it is attempted to secure a transport path having a length necessary for performing medium processing on the medium, the width required for the transport device is smaller than the configuration in which the medium is not transported in the height direction. . In addition, the width | variety here is a dimension of the conveying apparatus in the direction which goes to the post-processing apparatus 4 from the pre-processing apparatus 2. FIG. In the following description, “width” refers to this dimension. In the present embodiment, the medium conveyed in the first direction is also conveyed in the second direction opposite to the medium. As a result, when a transport path having a length necessary for medium processing is to be secured, the height required for the transport device is also smaller than in the configuration in which transport in the second direction is not performed.

[1-4] Arrangement of the first and second processing units and the first and second related members As shown in FIG. 2, the first related member 111 and the second processing unit 120 are arranged in the first direction A10 and the second direction. They are arranged in two directions A20. On the other hand, FIG. 3 is a diagram illustrating an example in which the first related member 111 and the second processing unit 120 are not arranged side by side in the first direction A10 and the second direction A20. In this example, the distance in the horizontal direction A101 between the first conveyance path 11 and the second conveyance path 21 is the sum of the width in the horizontal direction A101 of the first related member 111 and the width in the horizontal direction A101 of the second processing unit 120. It is necessary to be more than the value. In contrast, in the example of FIG. 2, the first related member 111 and the second processing unit 120 are arranged so that at least a part of each of them overlaps each other when viewed from the first direction A10 and the second direction A20. Therefore, the distance in the horizontal direction A101 between the first transport path 11 and the second transport path 21 is shorter than the example of FIG. Therefore, according to this embodiment, compared with the configuration in which the first related member 111 and the second processing unit 120 are not arranged side by side in the first direction A10 and the second direction A20, the preprocessing device 2 and the postprocessing device. The size of the transport device in the direction toward 4 is reduced.

  When the space is saved as in the present embodiment, the curvature of the folded conveyance unit 30 is increased, so that the medium conveyed through the folded conveyance unit 30 is strongly bent. The influence of this curvature is particularly great at the front end in the medium transport direction. If there is a processing position of the second processing unit 120 immediately after passing through the folding conveyance unit 30 in this state, the medium floats or the medium is positioned with respect to the second processing unit 120 while the medium is processed. May fluctuate, making it difficult to perform stable processing. As shown in FIG. 2 and FIG. 4B, if the distance from the folding conveyance unit 30 is set so that the second processing unit 120 is farther than the first processing unit 110, the folding is performed even when the space is saved. The influence of the curvature of the conveyance unit 30 can be reduced, and the posture of the medium is stabilized.

The 2nd related member 121 is arrange | positioned in the position which opposes the 2nd process part 120 on both sides of the 1st conveyance path 11, and performs the function regarding the process by the 2nd process part 120. In this example, the first processing unit 110 and the second related member 121 are arranged side by side in the first direction A10 and the second direction A20, and the first related member 111 and the second processing unit 120 are the first. Since they are arranged side by side in the direction A10 and the second direction A20, the size of the transport device in the direction from the pretreatment device 2 to the posttreatment device 4 is smaller than in the case where this configuration is not provided.
Further, according to this configuration, since the first processing unit 110 and the second processing unit 120 are arranged on the upstream side of the folding transport unit 30, the first processing unit 30 is less affected by the folding transport unit 30. Processing by the processing unit 110 and the second processing unit 120 is performed.

In this example, a transport device 3e that transports a medium along a transport path B1e indicated by a broken line is shown. The first direction A10e and the second direction A20e along the U-shaped linear portion of the transport path B1e (that is, the path along which the medium is transported in the first and second transport paths) are at an angle θ1 with respect to the vertical direction A102. Just leaning. Even if the first and second directions are inclined with respect to the vertical direction A102 as described above, if the first processing unit is disposed at a position closer to the folded-back conveying unit than the second processing unit, Compared to a comparative configuration (a configuration in which the second processing unit is not disposed at a position farther from the folding and conveying unit side than the first processing unit), the posture of the medium at the first processing position is easily stabilized.

The medium processing (processing performed on the conveyed medium) performed by the first and second processing units is not limited to the above-described image reading processing. For example, an ejection process for ejecting ink onto the medium may be performed as the medium process. The ejection process is also a process in which the processing result can change when the distance between the processing unit and the medium or the inclination of the medium with respect to the processing unit is changed, as in the image reading process, and the posture of the medium is stable. This is a desirable process. As long as such processing is performed, any processing may be performed as the medium processing.

[2-6]
The preprocessing device is not limited to the image forming apparatus described above. For example, an apparatus (also referred to as a decurler) for correcting a curl (rolled state) of a medium generated when an image is formed is disposed between the image forming apparatus and the conveying apparatus 3 as a preprocessing apparatus. Good. In short, the pre-processing device may be any device as long as the medium for performing the medium processing is carried out to the transport device 3.

[2-7]
The post-processing device is not limited to that described in the embodiment. For example, when the result data from the conveying device 3 indicates that the image is not accurately formed on the medium, the post-processing apparatus performs a process of cutting the medium and a display means or an operator's terminal A process for informing the user may be performed as a post-process. Further, the post-processing performed by the post-processing device may or may not be in accordance with the result of the medium processing performed by the transport device.

[2-8]
The present invention can be understood as a transport system including a transport device, a pre-processing device, and a post-processing device in addition to the transport device. The pre-processing device here is a device that performs a predetermined pre-processing on the medium and carries it out toward the transport device, and the post-processing device is a post-processing device that is determined with respect to the medium transported from the transport device It is an apparatus that performs processing. The image inspection system 1 described in the embodiment is an example of a transport system. The conveying device is also regarded as an image reading device when reading an image formed on a conveyed medium, and is also regarded as an image forming device when an image is formed on a conveyed medium. In short, the transport device in the present invention performs processing determined for a medium while transporting the medium.
