摘要： The mechanism disclosed herein is capable of adjusting the velocity with which a print element is projected toward a record sheet such that the impact velocity and, thus the impact forces, are controlled and varied. The control of the velocity with which the print element located on a shaft (22) is propelled against the record sheet is accomplished by a cam (26) which rotates with the print element during character selection and has thereon a plurality of rises corresponding to a displacement of a cam follower (30) engaged with a print cam (12). The print cam (12) is formed to present, in a plurality of different planes perpendicular to its axis, a like plurality of cam profiles and rises. By shifting the print cam follower (30) from one plane to another along the axis of the print cam (12) the velocity of the print element may be selected and controlled. This velocity selection is a direct result of the amount of rise in the cam (26) attached to the shaft (22) which rotates the print element.

摘要： Device for shifting a bifurcated character selection rack (12) between a first position and a second position, thereby engaging alternate portions (14, 16) of the rack with a pinion (18) controlling the rotation of the typehead (10) of a typewriter. The rack shifting mechanism (58,60,46,32) is controlled by a direct link (62) to the keyboard of the typewriter which responds to movement of a shift key-lever. The mechanism performs a force multiplication and, at the same time, a displacement division function to reduce a relatively large keylever and link displacement to a relatively small rack displacement. The rack shifting mechanism translates the rack to engage the alternate rack portion with pinion (18) thereby reversing the rotation of the pinion and allowing characters to be selected from the opposite hemisphere ofthetype element in response to a character selection input.
