Abstract
A nozzle unit is provided with nozzle heads of plural colors. Each nozzle head has a large number of ink-jet nozzles arranged side by side in the direction of main scanning. A head holder supports the nozzle unit in such a manner that the unit can move up and down between the printing position where printing is done on the printing sheet held on a rotating body and the non-printing position located above the printing position where the nozzle heads are maintained. The head holder is provided with a driving control circuit for driving the nozzle heads. The head holder, together with the nozzle unit, are movable vertically.
