Claims (1)

[Claims for Utility Model Registration] (1) A carriage B, which is disposed opposite to the document A that is fed in the sub-scanning direction Y and is driven reciprocally along the main scanning direction A printing head H that prints on an area of a certain length along the sub-scanning direction Y, an imaging optical system L that guides reflected light from an area of a certain length along the sub-scanning direction Y on the document A in a predetermined direction, and this optical system L. In a serial image scanner printer supporting an image sensor Im having a reflected light amount detection means G for detecting the reflected light amount guided by the imaging optical system L, a sample image that supplies a sample image signal to the print head H. a signal output means S; an image data storage means M1 to which a sample image reading signal obtained by reading a printed sample image by the image sensor Im is input and outputs image data; and an image data storage means M1 for outputting image data from the image data. A sensor positional deviation amount calculation unit C1 that calculates the positional deviation amounts Hd and Vd of the sensor Im, a positional deviation amount storage unit M2 that stores the positional deviation amounts Hd and Vd, and original read image data read by the image sensor Im. A serial type image scanner printer is provided with a document read image data correction means C2 for correcting the image data according to the amount of positional deviation. (2) The serial type image scanner printer according to item 1, wherein the positional deviation amount calculation means C1 calculates the positional deviation amounts Hd and Vd by detecting edges of the sample image. (3) The original read image data correction means C2 includes:
3. The serial image scanner printer according to claim 1 or 2, wherein the original read image data outputted by the image data storage means M1 is shifted in accordance with the amount of positional deviation. (4) The original read image data correction means C2 includes:
3. The serial image scanner printer according to claim 1 or 2, wherein the original read image data is shifted in accordance with the positional deviation amount and input into the image data storage means M1. (5) The above positional deviation amount is the maximum horizontal positional deviation amount Hd
5. The serial type image scanner printer according to any one of items 1 to 4, characterized in that: and vertical positional deviation amount Vd.
