動機構。 A yoke housing a coil bobbin for winding a coil is disposed inside a cylindrical printing ring with a large number of letters protruding around the periphery, and a fixed iron core is provided inside the coil bobbin, and by energizing the coil, the A movable iron core that is attracted to each of the fixed iron cores is provided, and a hammer whose tip presses the type of the printing ring when the movable iron core is driven is provided so as to be slidable in the axial direction of the coil bobbin. In the hammer drive mechanism of a small printer, a thin biasing plate extending substantially perpendicular to the sliding direction of the hammer is integrally provided on one side of the hammer, and the tip of the biasing plate is connected to the yoke. A hammer drive mechanism for a small printer, characterized in that the hammer drive mechanism is disposed on one side so as to apply an axial biasing force by the deflection of the biasing plate.
