構。 A yoke containing a plurality of coil bobbins for winding coils corresponding to the number of printed digits arranged in parallel is disposed inside a cylindrical printing ring with a large number of letters protruding around the periphery, and a yoke is arranged inside each coil bobbin. A fixed iron core and a movable iron core that is attracted to the fixed iron core by energizing the coil are provided respectively, and a hammer whose tip presses the type of the printing ring by driving the movable iron core is attached to each of the coil bobbins. In a hammer drive mechanism for a small printer that is arranged slidably in the axial direction, each of the fixed iron cores is integrally formed by bending the yoke, and the above-mentioned fixed iron core is formed integrally with one side of each of the hammers. A thin biasing plate extending substantially perpendicular to the sliding direction of the hammer is integrally provided, and the tip of the biasing plate is applied to one side of the yoke by an axial biasing force due to the deflection of the biasing plate. 1. A hammer drive mechanism for a small printer, characterized in that each coil bobbin is provided with an engaging portion that prevents each of the movable iron cores from protruding out of the bobbin.
