Printer apparatus and printed matter inspecting apparatus

A printed matter inspecting apparatus, comprising:

• an image sensing means for sensing a print medium constituting a print matter and reading image data on the print medium;
• an input means for inputting image data of each printing region of each print matter used to print the image to said print medium;
• an inspecting means for comparing said input image data of each printing region of each print matter and the image data read from said print medium corresponding to said input image data and inspecting whether at least one of contents and a state of printing are adequate or inadequate every print matter;
• and
• a printing means for printing a specific image indicating an invalid state when said inspecting means determines that at least one of the contents and the state of printing is inadequate.

A printer apparatus for successively printing input data, comprising:

• input means for inputting image data of each printing region of each print matter;
• printing means, having a printing head means in which a plurality of printing heads for printing dots at a predetermined pitch in predetermined printing regions are arranged so that the printing regions of the printing heads substantially continue with respect to a direction of a printing width which is perpendicular to a conveyance direction of the print medium, capable of performing the printing to the print medium with the printing width of the continuous printing regions formed by the plurality of printing heads by sub-scanning in a direction perpendicular to the direction of the printing width, for printing said input image data on a print medium;
• image sensing means for sensing the printed image on said print medium and reading the sensed printed image as image data;
• inspecting means for inspecting continuity of printing results by said plurality of printing heads based on the image data read by said image sensing means;
• and
• printing head moving means for moving said plurality of printing heads so that said continuity can be secured with a predetermined precision and for correcting a position of said plurality of printing heads.
