When the motor 1018 is in an activated state and the belt 1016 is rotated in the direction of the arrow R, the carriage member 1010 a of the recording part 1010 is moved in the direction of the arrow S by a certain distance. When the motor 1018 is in an activated state and the belt 1016 is rotated in the direction reverse to the arrow R shown in the drawing, the carriage member 1010 a of the recording part 1010 is moved in the direction reverse to the direction of the arrow S by a certain distance. Further, at one end of the movement driving part 1006, a restoration unit 1026 for performing ejection restoration of the recording part 1010 is provided facing to an ink ejection orifice array of the recording part 1010, at a position serving as the home position of the carriage member 1010 a.
In the recording part 1010, ink jet cartridges (hereinafter, simply referred to also as a “cartridge(s)”) 1012Y, 1012M, 1012C and 1012Bk are each mounted detachably on the carriage member 1010 a for each color, e.g., each of the colors of yellow, magenta, cyan and black.
