Abstract
A liquid discharge head unit is positioned in high precision when mounted on the carriage of a liquid discharge recording apparatus. For the liquid discharge head unit, a side extrusion formed in column, which is rotatively supported in carriage, presses the upper surface of guide ribs formed on both side ends on the upper rear portion. This upper surface is made higher toward the rear side in order to effectuate the substantially horizontal movement of the pressurized position from the front side to the rear side. Then, the liquid discharge head unit is rotated around the side extrusion formed in column so as to be mounted on the carriage smoothly. Lastly, a guide pin, a rear extrusion, and a lower extrusion are allowed to abut against the corresponding portions of the carriage by means of pressure exerted on a receiving rib in order to perform positioning in the front, rear, left, right, up and down directions exactly. Also, by means of pressure exerted on the side face, the side extrusion is allowed to abut against the corresponding portion of the carriage to position the circumference of the guide pin in the rotational direction.
