<P>PROBLEM TO BE SOLVED: To obtain printing equipment having a drive control means by which the stability of the rotation of a printing drum to the fluctuation of a load is ensured, and a ununiform image caused by the rotational fluctuation can be suppressed. <P>SOLUTION: The printing equipment having the printing drum 1, a motor 71 for rotationally driving the printing drum 1 and a control means for controlling the drive of the motor is so constituted as to intentionally operate a rotational load on the motor by a braking means 72 by providing the braking means 72 for intentionally giving the rotational load to the motor 71. As a result, even if abrupt load fluctuation occurs during the rotation of the printing drum 1, the generation of the slippage of a phase in phase control to the abrupt load fluctuation can be suppressed. Accordingly, no rotational fluctuation of the printing drum caused by the slippage of the phase develops, thereby preventing the ununiform halftone image caused by this from developing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
