MECCANISMO DI SELEZIONE PER MACCHINE STAMPATRICI A SINGOLO ELEMENTO

摘要

A selection mechanism is disclosed which employs a controlled steerable follower for selecting and following a cam groove in a barrel cam to cause relative translation between the barrel cam and the cam follower. The motion of the barrel cam while translating is converted into rotary motion to rotate a single element on a single element printer to accurately position a selected row of characters adjacent the print point. A similar follower is used to cause translational movement of the tilt cam and a bell crank and link arrangement is used to translate the lateral movement of the tilt cam to the type element.
