Abstract
A paper feeding mechanism wherein tractors which convey a sheet of paper by means of belts when a driven shaft connected to a drive gear is rotated are supported swingable round a support shaft to move from their closed position to their open position and vice versa, characterized by a stopper member having those teeth which are selectively engaged with the drive gear to stop the rotation of the drive gear, and by a drive member for driving the stopper member to engage its teeth with the drive gear only when the tractors are under their open position. The free running of the belts can be this prevented when the tractors are under their open state, thereby allowing the sheet of paper to be stably mounted.
