PURPOSE:To facilitate the control of emission timing, by arranging opposed emitting orifice rows of adjacently arranged liquid droplet emitting heads so as to bring the interval between said orifice rows to the integer-folds of a dot pitch and to one over integer number of the feed pitch of an object to be printed. CONSTITUTION:Each liquid droplet emitting head 1' is driven in a state fixed to a carriage. A liquid droplet emitting apparatus having a width larger than that of an object 7 to be printed is arranged so as to become vertical to the scanning direction of the object 7 to be printed and the mutually adjacent liquid droplet emitting heads 1' are arranged so as to bring the interval l' between the rows of opposed emitting orifices 9 to the integer-folds of a dot pitch and one-integers of the feed pitch of the object 7 to be printed or the integer-folds thereof. By this arrangement, a dot can be printed at an accurate dot pitch only by moving the object 7 to be printed and, in a printer equipped with this liquid droplet emitting apparatus, positional adjustment requiring preciseness between liquid droplet emitting heads, which has been performed by every conventional printer so far, becomes unnecessary. |
