Abstract:
A drum type printer comprising:a machine frame,a printing drum,a back press roller for pressing a print sheet to the printing drum;frame means for supporting the printing drum to be rotatable around a central axis thereof,the machine frame having guide-hold means adapted to removably engage a part of the frame means for guiding and holding the frame means so as to be movable along the central axis of the printing drum, and drawably receiving the frame means and the printing drum supported thereby,printed image transverse position adjustment means including a shift member mounted in the frame means so as to be shiftable along the central axis of the printing drum along a shift path relative to the frame means at least as much as a shift distance corresponding to a maximum value of an adjustment of a transverse position of a printed image, drive means for selectively shifting the shift member relative to the frame means along the shift path, and latch means for selectively latching the shift member at a part thereof to the machine frame when the frame means are at an installed position thereof in the machine frame, such that a shifting of the shift member relative to the frame means along the shift path effected by the drive means with the latch means latching the shift member to the machine frame adjusts the transverse position of the printed image.
