ABSTRACT:
An ink-jet head assembling apparatus assembles a nozzle head of an ink-jet head for discharging an ink in a predetermined pattern from a heater board having a plurality of heaters for heating the ink, and a top plate member having a plurality of discharge orifices for discharging the ink heated by the corresponding heaters in a jet-like manner. The apparatus is provided with a first position detection mechanism for measuring forming positions of the discharge orifices of said top plate member, a second position detection mechanism for detecting arranging positions of the heaters on said heater board, a position adjustment mechanism for comparing a first detection result detected by said first position detection mechanism with a second detection result detected by said second position detection mechanism, and moving said top plate member relative to said heater board by a shift amount between the two detection results so as to align the positions of the heaters with the positions of the corresponding discharge orfices, and an adhesion mechanism for adhering said top plate member and said heater board aligned by said position adjustment mechanism to each other.
