A pressing board operation mechanism for paper cutter includes an eccentric driving rod to pivot a first link assembly composed of two pairs of triangular plates and the first link assembly is connected to a second link assembly which includes a rack member, two first links and two second links. The two first links are operationally connected to the rack member by two respective rack ends and the two second links are pivotably connected between the first links and the pressing board which is lowered or lifted by the pivotal movement of the first and second links. Two sensors are provided and activated when the first link assembly is moved to a pre-set positions and the sensors send commands to stop the motor.
