Problems solved by technology

However, it takes time to inspect due to the amount of image data and inspection content, and sometimes the inspection of the image of the printed matter cannot be completed until the printed matter reaches the switching position of the discharge path. Therefore, a countermeasure is being studied.

Embodiment Construction

[0040] Hereinafter, embodiments of the inspection apparatus and image forming apparatus of the present invention will be described in detail with reference to the drawings.

[0041] figure 1 It is a schematic diagram showing the outline of a printing system including the inspection apparatus of this embodiment. The printing system includes: a printing device 100 that generates a printed matter; an inspection device 200 that inspects an image of a printed matter generated by the printing device 100; and a post-processing device 300 that performs post-processing on the printed matter determined by the inspection device 200 that there is no defect in the image.

[0042] The printing device 100 prints an image on a printing medium supplied from the paper feed cassette 110 based on the original image to generate a printed matter. The method of the printing process includes, for example, an electrophotographic method and an inkjet recording method. In the case of the electrophotographic...

Abstract

The invention provides a checking apparatus and an image forming apparatus which can significantly reduce the production rate and can properly switch the discharging destination of articles to be printed. A plurality of second conveying zones (202a-202g) are arranged on the conveying path of the articles to be printed. A conveying control unit distributes the articles to be printed, of which the image read by an image reading unit (220), to the plurality of second conveying zones (202a-202g), and the articles to be printed wait in the second conveying zones until an image checking unit finishes the checking of the image and the articles to be printed after the image checking is finished are conveyed to a third conveying zone (203) at the rear stage.

Description

Technical field [0001] The present invention relates to an inspection device and an image forming device for inspecting an image of a printed matter. Background technique [0002] Conventionally, there is known an inspection device that inspects an image of a printed matter generated by a printing device. The inspection device reads the image of the printed matter while transporting the printed matter discharged from the printing device to the downstream side, and compares the original image used when the printing device generates the printed matter with the read image read from the printed matter, thereby inspecting the printed matter Whether the image is defective. On the downstream side of the reading position where the image of the printed matter is read, a switching device that switches the discharge destination of the printed matter based on the inspection result of the image is provided. The printed matter determined to be defective in the image is guided by the switchin...
