PURPOSE:To easily irradiate a moving article with an electron beam through a simple improvement by so setting an arraying direction of electron sources disposed along a longitudinal row as not to cross the arraying direction of electron sources disposed along a lateral row. CONSTITUTION:The arraying direction of electron sources 3 disposed along a longitudinal row is so set as not to cross the arraying direction of electron sources 10 disposed along a lateral row. Thus, since the lateral and longitudinal directions of the matrixlike sources 3, 10 disposed on a board 1 are not perpendicularly crossed, if a moving article is continuously radiated with an electron beam from the sources 3, 10, the entire sources 3, 10 of one row can be sequentially driven (linearly and sequentially drive) under a pure control within time moving the article between the source 3 and the adjacent source 10. Thus, continuous electron beam irradiation region is formed by simple means, and signal setting for control is simplified, and further a control circuit is simplified due to the simplification. |
