摘要：
Described is a print wheel type printer having selection pawls (6), a reset lever (8), shaft holes (1f) for supporting a selection pawl shaft (7), a reset lever shaft and a reset cam shaft (9), and print wheel positioning pieces (3) constructed as a unit in a trigger unit case (1) in order to make the relative positioning between print wheels (11) and parts of a character selection mechanism easy. For positioning the unit case (1) on a main housing frame of the printer, guide projections are formed on the sides of the unit case (1) to be engaged with positioning grooves on the main housing frame.
