Abstract (en)
[origin: US4500219A] A paper guiding device and operating method for use in an office writing machine, the device including a platen carried by a shaft and constituting a paper support, the platen shaft and platen being rotatable in a first direction for insertion of a paper sheet in the machine and in a second direction opposite to the first direction, a paper holding rail disposed adjacent the platen and carrying a plurality of pressure rollers which are pressed toward the platen, a rocker member supporting the rail and mounted to undergo pivotal movement about the axis of rotation of the platen shaft between a paper insertion position and a normal printing position; and a coupling member coupling the rocker member and platen such that rotation of the platen in the second direction effects pivotal movement of the rocker member into the paper insertion position for insertion of the leading edge of a paper sheet between the rollers and the platen and rotation of the platen in the first direction effects pivotal movement of the rocker member into the normal printing position, with simultaneous transport of the paper sheet, while the rollers maintain the sheet flat against the platen, the normal printing position being sufficiently remote from the printing line to assure that the printed characters will not be smeared upon contact with the rollers.
