PURPOSE:To print a large number of stamps in a short time by a method in which stamps to be sand-blasted are arranged in every direction and housed in a stamp box, and while moving the stamp boxes by as many number as one row each in one direction, a nozzle is moved on the stamp boxes in every direction. CONSTITUTION:A large number of stamps N are arranged and housed in a stamp box divided into many sections vertically and horizontally by partition walls. The stamp boxes are moved in the sideward direction (a) along a guide rail 3 by as many numbers as one row each of stamps N intermittently. A given mask is attached to the tips of the stamps N in advance. An abrasive and an air jet nozzle 9 are moved in the orthogonal direction to the moving direction of the stamp boxes along the guide rail 10. |
