Abstract

PURPOSE:To save consumption of power and to improve properties of a printer in the printer head of a wire dot printer, by a method wherein electric energy supplied for electromagnet mechanisms is changed in proportion to the number of excited electromagnet mechanisms. CONSTITUTION:When a printing information is input to a buffer 22, an electromagnet mechanism 20 to be excited according to this information is determined and the output is given to a magnet drive circuit 23 and a dot counter 25. The dot counter 25 counts the number of electromagnet mechanisms 20 which are simultaneously excited and outputs the number to an exciting-time-selecting-circuit 26. On the exciting-time-selecting-circuit 26, an exciting time in proportion to the number of simultaneous exciting mechanisms is selected according to a program and output to the drive circuit 23. The drive circuit 23 excites the coil 20b of the electromagnet mechanism 20 and makes a printing motion synchronizing with signals of a dot pulse generator 27 on basis of the input from the buffer 22 and the selecting circuit 26.
