PROBLEM TO BE SOLVED: To provide an OCR test sheet that is suitably used to perform the fine adjustment with high accuracy for an image which is read by a camera of an OCR processor. SOLUTION: A synthetic paper is used as a base material 2 of an OCR sheet 1, and an OCR test pattern 3 consisting of the density controlled timing marks, lines, etc., is printed on the surface of the material 2 with an adhesive layer 4 formed on the entire back of the material 2 respectively. The layer 4 uses a material that can be repetitively stuck to and removed from the material 2 and consists of a peelable paste. Thus, even the projecting/recessing parts or curled parts if caused on the material 2 of the sheet 1 can be set close and flat on a face plate placed at the camera reading position like other parts of the material 2 by the adhesive strength of the layer 4. |
