PURPOSE:To make the head element structure of upper and lower columns identical to each other by constituting the titled printer such that a shift direction of a data signal of each head element of the upper column and that of the lower column are reversed to each other. CONSTITUTION:The head unit 1 is provided with plural head elements HE1-HE14 arranged in zigzag on upper and lower columns and the elements of an odd number order are arranged to the lower column and those of an even number order are arranged on the upper column respectively. The elements on the upper column are fitted in the normal upper/lower attitude and the elements of the lower column are fitted in the attitude taking upside down together with shift registers SR1, SR3-SR13. Shift registers SR2, SR4-SR14 corresponding to the elements of upper column are connected so that the data signal is inputted from the left sequentially. On the other hand, the shift registers SR1-SR13 of the lower column are connected reversely to the shift direction of the shift registers of upper column.
