In a calculating machine of the type disclosed when no numeral or decimal point is printed, no signal is transmitted to the printing device or non-printing signals are transmitted thereto so that a type bar is lifted to its uppermost position. In this position, a type bar stopper provided upon a guide plate which serves to prevent the lateral vibrations of the type bar and to guide a hammer engages with an engaging member formed upon the type bar. In consequence, the type bar is prevented from striking a paper, that is, is locked in non-printing position. The conventional type bar locking elements may be eliminated.
