。 A type shaft rotatably driven by a drive motor is installed in the frame of the printer, and a plurality of type wheels each having a plurality of types protruding from the outer periphery are attached to the type shaft in parallel, and an ink ribbon is attached to each type. In a microprinter having a hammer mechanism for pressing paper, a sensor plate having a slit corresponding to each type position on the type wheel is attached coaxially to the type shaft, and a sensor plate having a gear ratio is attached to the type shaft. A type gear having a two-stage gear for selecting different type and resetting the type is installed, and a two-stage main gear is provided which is meshed with each gear of the type gear and rotationally driven by the drive motor, and when selecting the type. A microprinter characterized in that the rotational speed of the type gear is changed between when resetting the type and when resetting the type.
