Image printing apparatus

Abstract

In order to realize stable image printing, this invention provides an image printing apparatus capable of supplying a stable voltage to a printhead, and maintaining a compact shape. For this purpose, in the image printing apparatus in which a carriage which supports a printhead is scanned on a printing medium to print an image, a power converter which converts power to be supplied to the printhead is mounted on the first print circuit board of the carriage so as to supply a predetermined voltage to the printhead. The printhead, and a power smoothing unit which smoothes the voltage converted by the power converter in accordance with the load of the printhead are mounted on the second print circuit board. The first and second print circuit boards are separately arranged at a proper gap in the image printing apparatus, which prevents an increase in the size of the image printing apparatus.
