Abstract
The present invention is directed to realize a portable, compact, light, thin, inexpensive and fast printer apparatus. A motor is provided between a printing head unit and a stationary frame member to drive the printing head unit relative to the stationary frame member in leftward and rightward directions, thereby eliminating conventional indirect driving components such as a stepping motor and a lead screw. Further, a sensor is provided in the printing head unit to detect a moving velocity and a position of the printing head unit to thereby construct the printer apparatus having reduced number of components to ensure stable driving and high accuracy. According to such a construction, the motor is integrated into the printing head unit, which self-moves in the printer apparatus to eliminate a mechanism converting a rotational movement into a linear movement, thereby achieving cost down of the printing apparatus.
