ABSTRACT:
The paper transport shaft of a paper feed mechanism is movably mounted on an arm of a frame-supported spring wire lever. Another arm of the spring wire lever is pivotably mounted and may be set to flex the body of the spring wire lever through a pivot lever. Depending on the pivoting of the pivot lever the contact pressure between a paper pressure roller mounted on the paper transport shaft and a platen is varied. Selectively, the paper transport shaft can be pivoted away from the platen to allow adjustment of the paper inserted in the paper feed mechanism.
