POSITION CORRECTION APPARATUS, LIQUID EJECTION APPARATUS, AND METHOD FOR CORRECTING POSITION
First Claim
1. A position correction apparatus that corrects a position of a liquid ejection unit ejecting liquid toward a conveyed object, the position correction apparatus comprising:
- a position detection unit configured to detect a position of the conveyed object in a width direction of the conveyed object;
a moving unit configured to move the liquid ejection unit in the width direction;
a moving amount determination unit configured to determine a moving amount of the liquid ejection unit in the width direction based on a position of the conveyed object in the width direction;
a moving speed determination unit configured to determine a moving speed of the liquid ejection unit in accordance with a conveyance speed of the conveyed object; and
a move control unit configured to control the moving unit so as to move the liquid ejection unit at the moving speed and by the moving amount in the width direction.
