摘要： A feed roller device of a typewriter used for reliably urging a sheet of paper to be printed against a platen. In this feed roller device, a pair of feed roller assemblies are parallelly arranged in parallel to the axial line of the platen and rocking levers are provided at the central positions in the axial lines of the feed roller assemblies, respectively. Each of these two rocking levers is rockingly supported by a typewriter frame, pivotally supported at one end thereof by a connecting rod of one of the feed roller assemblies and provided at the other end thereof with a spring, which urges the feed roller assembly against the platen by the urging force thereof. Consequently, only two springs are used, so that the adjustment of the feed roller assemblies urging the platen in urging force can be facilitated.

摘要： This invention is a platen knob device in a typewriter for releasing a platen of the typewriter from a platen pitch feed mechanism and changing the platen over to a continuous feed. This platen knob device includes a platen variable fixed onto a platen shaft and a platen driver operative in association with the platen pitch feed mechanism and slidably provided on the platen shaft. The platen driver is urged by the platen variable through a spring, whereby the platen driver and the platen variable are engaged with each other, in which condition, if the platen knob is rotated, then the platen is changed over to the pitch feed. If the platen knob is urged in a direction opposite to the direction in which the platen knob is urged by the spring, then the platen driver is urged against an end face of a cylindrical portion of the platen knob to move in the axial direction thereof and separated from the platen variable to change the platen over to the continuous feed.
