PURPOSE:To obtain a print hammer attachment position with high accuracy, by bringing a standard for attaching a print hammer positional determination instrument to the attachment surface of a type selecting motor to a frame. CONSTITUTION:The flange surface 14 of a type selecting motor 13 usually has a highly precise flatness degree. The frame 15 having the motor 13 attached thereto has holes 15a, 15b and a notch part 15c as the exposed regions of the flange surface 14 and the feet 12a, 12b, 12c of a print hammer positional determination instrument 12 can be contacted with the flange surface 14. The before and behind position of the print hammer 16 is determined at the end surface of the print hammer positional determination instrument 12 and the height position thereof at the end surface (f) thereof while the left-and-right position thereof at a groove width (g). The under-surface, that is, the end surface (h) of the print hammer positional determination instrument 12 determines the attachment position of the attachment mount 18 of the type body 17. |
