A line thermal head printer device of which size is made remarkably smaller is provided. A stepping motor ( 10 ) rotationally driving a ribbon tape reel is arranged to be fitted to one corner portion of a frame plate ( 9 ). A line thermal head ( 11 ) is arranged to be fitted to a corner portion of the frame plate ( 9 ) adjacent to this one corner portion. A ribbon tape winding drive shaft ( 2 ) and a ribbon tape unwinding drive shaft ( 1 ) are arranged on one side of the stepping motor ( 10 ) and the line thermal head ( 11 ), respectively, to be fitted to the frame plate ( 9 ). By this arrangement, parts and components are efficiently arranged without unused space on a surface of the frame plate ( 9 ) of a square or rectangular shape. Also, a ribbon tape ( 3 ) fed between reels fitted to the drive shafts ( 1, 2 ) is led around the parts and components, that is, along a periphery of the frame plate ( 9 ). Thereby, the parts and components are effectively arranged on the surface of the frame plate ( 9 ) and the construction can be made remarkably smaller.
