Abstract

PURPOSE: To obtain the typewriter absorbing a shock upon printing by the compressibility of a gas to suppress the noise thereof as much as possible, capable of printing under a constant printing pressure and providing a clear printing by a method wherein the type therefore is driven to strike the platen thereof by a cylinder utilizing pneumatic pressure to effect the printing.
CONSTITUTION: The typewriter is constituted so as to effect the printing by driving the type A to strike the platen 2 by the cylinder 15 utilizing the pneumatic pressure. Further, a hammer 3 for picking up the type from the container 1 of a group of types and striking it to the platen 2 to effect the printing is provided. The hammer 3 is pivotally supported to a transversally movable base 10 with a pin 9 and a long hole 11 extending axially is provided at the loose end thereof. This long hole 11 is loosely engaged with one end of a link 14 through a pin 13 while the other end of the link 14 is connected to a piston rod 16 for the pneumatic cylinder 15. The cylinder 15 moves a piston 17 by the pneumatic pressure acting to a cylinder chamber 21 while the piston is returned to the initial position thereof by the resilient force of a spring 18 in a spring chamber 22. The striking of the hammer 3 is effected by a switch 7 provided on a handle 5.
