摘要： There are provided an operating mechanism 5 having an operating portion, for example, freely rotatable roller 4, which is displaced to a setting position Ps of pressure-contacting to the plate belt 2 by a spring member 3 and a releasing position Pr spaced apart from the plate belt 2, a fore clamping mechanism 8 supported in a seasaw manner on widthwise supporting shafts 6 . . . disposed on the plate belt 2, and having clamping portions 7c . . . for clamping a fore portion of the plate S at one end thereof, operated portions 7m . . . pressed by the freely ratable roller 4 at the setting position Ps, at the other end thereof, and fore clamps 7 . . . pressed in a clamping direction by spring members 9 . . . , and a rear clamping mechanism 12 supported in a seasaw manner on a widthwise supporting shaft disposed on the plate belt 2 at a rearward of the fore clamping mechanism 8, and having a clamping portion 11c for clamping a rear portion of the plate S at one end thereof, operated portions 11m . . . pressed by the freely rotatable roller 4 located at the setting position Ps, at the other end thereof, and a rear clamp 11 pressed in a clamping direction by spring members 13 . . . . Thereby, a miniaturizing of the whole printing machine can be caused, and further a reliability and a maintainability thereof can be improved.
