PROBLEM TO BE SOLVED: To make swing oscillations generated to a desk disappear at the time of printing operation by detecting the swing oscillation of a housing because of a reciprocatory motion of a carrier and controlling a cycle and a timing of the swing oscillation of the housing in an apparatus having the carrier which reciprocates and carries a printing head thereon. SOLUTION: When a printer apparatus 1 operates to print, a swing in a lateral direction generated by a reciprocatory motion of a carrier 20 is transmitted to a desk 5 loading the apparatus 1 and the desk 5 generates a swing oscillation in the same direction as the carrier 20. A swing acceleration-detecting sensor having a weight held between two confronting piezoelectric elements is set to an appropriate position of a housing of the printer apparatus 1, thereby detecting the swing oscillation of the housing due to the reciprocatory motion of the carrier 20. A cycle of the swing oscillation and a timing of the swing of the housing are controlled in accordance with the detection result of the swing oscillation. For example, a stop time when a movement direction of the carrier 20 is switched is changed, or a movement speed of the carrier 20 is changed, whereby the oscillation is disappeared.
