PROBLEM TO BE SOLVED: To reliably detect this, and remove a base board even when a film tears and remains on the base board at separating time by arranging a control device to make an outside part of a base board width in a film detecting device nonoperable or cancel an output signal according to a signal of a base board width from a base board width detecting means. SOLUTION: Respective sensors in upper side and lower side film detecting devices 94A to 94D and 96A to 96D are selectively put in an actuating condition by a control device 58 according to a moving distance of edge aligning outside sensors 52L and 52R, that is, a width of a protective film. When a separated film is discharged outside of a path line, the upper side and lower side film detecting devices 94A to 94D and 96A to 96D confirm the completion of discharge by detecting the tail end of the film. When the completion of discharge is not confirmed nothwithstanding separated film detecting sensors 66A and 66B detect the tip of the film, it is judged as a separation error or a jam of a belt. |
