Abstract
PURPOSE: To obtain a low cost printer which does not require a hammer-driving part which drives all of hammers for one line of types at the same time by a method wherein printing is conducted as the number of hammers which are driven at the same time is limited.
CONSTITUTION: A scanning start signal is supplied to a printing character memory 7 in which one line of character information and a position information are stored and the memory 7 supplies printing character one by one and the position information to a dicision circuit 8. At the same time, projection parts on types of a type belt 1 are detected by a type position detector 5 and the signal is outputted. The signal of a type position counter 6 is counted up and outputted to a circuit 8 where the printing character, the position information and the count value are composed with each other. When these signals agree, they are supplied to a hammer drive part 15 through a gate circuit 9. The position information corresponding to the decision, at the same time, is supplied to the hammer drive circuit in the drive part 14 through a decoder 13 and then a drive signal is outputted from a drive signal generator 11 through an electric current driver 12, then, a hammer 2 corresponding to the hammer drive circuit is driven and corresponding types are printed on a form 4.
