PURPOSE:To facilitate the preparation of change-over among sheet sizes by fitting a pair of levers which are arranged adjacent to each other and are pivotally mounted thereto with rolls, releasably on a rotary shaft, and by forming a stopper part on one of the pair of the levers. CONSTITUTION:If a sheet cutting device 10 has two rotary blades 12, 13, two cutting operations are effected per one revolution of a cutter barrel 11 so as to cope with a half cut size sheet. However, if a sheet cutting device 10 has only one rotary blade 12, it copes with a whole size sheet. In the case of the half-size sheet, when one of kicker levers 44 adjacent to a kicker device 40 and a split clamp are loosened and rotated until a pin 44b abuts against a stopper part 44a, kicker rolls 43 which are in phase in the case of the whole size sheet, becomes out of phase from each other by 180deg. so as to cope with the half-size sheet. It is similar when the kicker rolls 43 are returned to be in phase upon change-over to the whole size sheet. Accordingly, it is possible to facilitate the adjustment of the kicker device 40. |
