Claims

[Scope of utility model registration request]

In a printing machine where printing paper stacked on a paper feed table is regulated in the width direction by a paper feed side plate and fed to the printing section, the printing paper printed in the printing section is ejected while curved on both sides of the edges. When the paper ejection roller system that transports the paper, the motor that drives the paper ejection roller system in this axial direction, and the paper feed side plate is moved in the width direction according to the size of the printing paper, the circuit changes from an equilibrium state to an unbalanced state. a bridge circuit that changes state, and drives the motor until the bridge circuit returns to an equilibrium state to transport the paper ejection roller system to a position corresponding to the size. Paper feed and discharge system interlocking device.
