ABSTRACT:
A cam shaft 23 is rotated 90 degrees when the plate 10 is fitted on the plate cylinder 60. Thus, as a result of the rotation, a flange part 3T of the tail edge side clamping base 3 is pushed by movement of a spring base 15 which receives a pushing force generated by springs 16. Therefore, the plate 10 is pulled in a tension applying direction. Since the tail edge side clamping base 3 does not receive the limitation of the cam shaft 23 directly, the tail edge side clamping base 3 can be moved in a direction parallel to a shaft of the plate cylinder 60. Thus, a diagonal image adjustment of the plate can be done easily.
