ABSTRACT:
A motion transfer mechanism for a machine includes a coupler interconnecting a one-arm crank member and the first crank arm of a two-arm crank member. A driving plate is mounted rotatably on the machine and has a cam edge. Any line, which connects any pair of points on the cam edge and also passes through the rotating axis of the driving plate, is at a predetermined distance. An input unit is connected to the driving plate so as to rotate the driving plate. A pair of roller followers are mounted pivotally on the coupler in association with the cam edge of the driving plate. The connecting line of the roller followers passes through the rotating axis of the driving plate. An output unit is connected to the second crank arm of the two-arm crank member. When the driving plate is rotated so that the roller followers slide along the cam edge of the driving plate, the one-arm and two-arm crank members are rotated so as to activate the output unit.
