Info
The output link (in blue), a rocker, remains stationary briefly in the beginning of the simulation. The coupler point on the coupler link (in black) of the fourbar linkage (in red and black) traces a curve containing an approximate circular arc. As the connecting link (in green) moves in this segment, the lower point of the link remain approximately stationary (as it is at the center of the circular arc), and therefore the rocker remains stationary.
