Abstract: In a printer, an MPU makes a flash ROM store a temperature read by a temperature sensor at the time of setting of a correction value and a misalignment correction number indicating a misalignment correction value. At the time of reciprocating print motion of a printer, the printer makes the temperature sensor measure an actual ambient temperature before backward printing and obtains a difference between the present temperature and the temperature at the time of setting of the correction value. A print start delay time which indicates timing between a point of time of driving a carriage motor and a point of time of starting the backward printing is corrected in accordance with the temperature difference. The printer starts the backward printing at the timing delayed for the corrected print start delay time.

Abstract: An electroacoustic transducer adapted to be mounted on a printed circuit board in which a coil spring is accommodated and supported in a cylindrical recess of a frame while it is fixed to neither a terminal plate nor the frame. Particularly, a protruding pin of the coil spring is passed through a though hole of the terminal plate to allow a leading portion of the protruding pin to be hooked thereon. When the electroacoustic transducer is mounted on the printed circuit board, any horizontal displacement between the compressed spring and the printed circuit board would not cause stress concentration on the coil spring since the coil spring is onlly horizontally shifted in the cylindrical recess until a coil portion of the coil spring hits against the wall of the cylindrical recess.
