Claims

[Scope of utility model registration request]

A pair of left and right holders are slidably fitted to a drive shaft and a guide shaft parallel to the platen, and a rotary body driven by the drive shaft to feed paper with feed holes formed on both sides is provided on the holder, In a pin feed mechanism in which both ends of a drive shaft and the guide shaft are attached to a support body, a pair of left and right frames hold the guide shaft to form a holding part that serves as a rotation fulcrum of the support body, and one of the frames two idler gears located at upper and lower positions on a radius around the guide shaft are connected to the motor so that the rotation directions are opposite, and one end of the drive shaft is meshed with one of the idler gears. An input gear is fixed, and a leaf spring is provided on the frame at a radius centered on the guide shaft, and elastically engages with the tip of the support to move the support into an upper tension position and a lower push position. A paper feeding device for a printing machine, characterized in that the leaf spring is formed with three engaging portions that are selectively positioned at one position and an intermediate position.
