Abstract

PURPOSE: To detect the malfunction of a type wheel upon stopping and improve the reliability of the printer by a method wherein a means to detect the existence of a pulse from a type position signal generator upon the stopping of the type wheel is provided in the stationary printing type printer.
CONSTITUTION: When a pulse corresponding to a type positioning one position before the type to be printed is outputted from a type detecting device 14, an electromagnet for driving a control lever is excited in order to change-over a clutch so as to stop the type wheel at the leading edge of the pulse. At this moment, if the stopping position of the type wheel is mistaken due to the decrease of the voltage of a battery or the like and a type "5" or a type "7" which are positioning before or after the desired type "6" is selected, there is a chance wherein a type position detecting signal W is put ON-OFF after an electromagnet driving signal M is put OFF or the electromagnet driving signal M remains in a condition of ON. Then, the signal is inputted into an OR gate 28 through an AND gate 27 or the same 31 and a malfunction detecting signal is outputted.
