A continuous working device is provided with a film working mechanism (3) for forming holes (A) in a film (F), a holding mechanism (4) mounted integrally with the film working mechanism (3), a slider (2) for supporting the film working mechanism (3) and the holding mechanism (4) such that the mechanisms (3, 4) can reciprocate in a direction (P) of conveyance of of the film (F), and a return mechanism (5) for returning the film working mechanism (3) and the holding mechanism (4) to original positions on the opposite side of the conveying direction (P) of the film (F). When the film (F) is held by the holding mechanism (4), the film working mechanism (3) can be moved in synchronism with the film (F). As soon as the holes (A) are formed in the film (F) by the film working mechanism (3), the holding mechanism (4) is separated from the film (F) and the return mechanism (5) can return the film working mechanism (3) and the holding mechanism (4) to the original positions. |
