PURPOSE: To automate adjustment of a printing position of a rubber stamp by providing a comparison operation circuit for obtaining a misregistration quantity of a mark image and a robot control unit for controlling drive of a robot based on the misregistration quantity. CONSTITUTION: On a main face of a stage 2, positioning blocks 10a and 10c which are respectively arranged on lines intersecting at right angles are fixed. A matter to be marked 1 is laid on the stage 2 so as to come into contact with the inside faces of the positioning blocks 10a and 10b, so that it is laid on the stage 2 always in a fixed state. A head 3 positioned at a position to be called a tip of an arm of a robot 5 can be controlled so as to move smoothly in a three-dimensional manner. Accordingly, a bottom face of a rubber stamp 4 adhered to the bottom face of the head 3 by using a double-sided tape is brought into contact with a stamp 6 so as to attach an ink. Thereafter, a desired mark 7 can be printed on the top face of the matter to be marked 1 on the stage 2. |
