Keyboard for typewriters or similar machines
摘要:
A keyboard for typewriters or similar machines has a key support, switching contacts and key push rods, each of which is acted upon by a spring. The design of the few individual parts assures their simple manufacture (extruded parts and a stamped part) as well as an assembly just as simple and therefore automated, and, if desired, even without screws or aids of that type. Activation of the individual keys takes place with satisfactory tactile feedback and without undesireable vibrations.
