ABSTRACT:
A pair of main frames extend in frontward/rearward direction of a printer body. The pair of main frames are pivotally supported on a guide shaft and laterally movable therealong. The main frames are slidingly guided by a guide member through abutment members. The abutment members are supported on the main frames and are rotatably connected to adjusting plates which are also supported on the main frames. The adjusting plates are positionfixably adjustable relative to the main frame for controlling angular orientation of the main frames. Reference holes are defined in the main frames by which a print hammer is supported. The adjusting plates which support the abutment member engaging a guide member are fastened to outer surfaces of the main frames. The adjusting plates have recesses in confronting relation to the respective reference holes. When the reference holes are moved back and forth with respect to a central position in the recesses, the print hammer is moved back and forth about a guide shaft for thereby varying the stroke of the print hammer.
