PURPOSE: An operating device of a pinch roller for a digital printing machine is provided to simplify a structure by rotating a shaft connected to a feeding device through a bracket. CONSTITUTION: A cylinder unit(10) performs a forward-backward motion. A bracket unit(20) performs a linear reciprocating motion by the cylinder unit. A connecting unit(30) converts the forward-backward motion of the bracket unit into the reciprocating rotational motion of a shaft(71). A hole is prepared in the end of a forward-backward portion of the cylinder unit. A slot hole(54) of the bracket unit is corresponded to the hole. The cylinder unit and the bracket unit are coupled with a clamping unit(56) inserted into the hole and the slot hole.
