Image forming device

摘要

An image forming apparatus comprising:
a carriage (10) which reciprocatingly moves substantially perpendicular to a feeding direction of a sheet (P);
a recording head (15) mounted on the carriage (10) for performing printing on the sheet (P);
reciprocating movement means which accelerates the carriage (10) in one direction into a constant speed state, decelerates the carriage after the constant speed state for a short time, accelerates the carriage in the opposite direction into the constant speed state again, and decelerates the carriage to repeatedly and reciprocatingly move the carriage;
first determining means which determines that the carriage is stopped when the carriage is decelerated to a speed equal to or lower than a first speed so as to stop at a predetermined position; and
second determining means which determines that the carriage moved by the reciprocating movement means is stopped when decelerated to a speed equal to or lower than a second speed higher than the first speed to perform a print operation.
