Abstract

PURPOSE:To obtain a print, having uniform dot intervals, in a simple mechanism, by a method wherein, in a device in which a wire, forming dots, prints as it moves, the wire is struck in synchronism with a given position detecting a wire position. CONSTITUTION:The end of a striking wire 5 is moved vertically through the rotation of a cam 10, and with this dots in a longitudinal row are printed. After said printing is complete, a whole printing head is moved horizontally to perform a printing of dots in a subsequentlongitudinal row. In this case, a disc 15, which rotates in conjunction with the cam 10, is located, and timing signals 25 are obtained in such a manner detects a great many holes 19 perforated along the circumference of a circle of the disc 15 by means of a photo diode 17 and a photo transisitor 18. Said signals and pulse signals 24, corresponding to a dot pattern obtained from a photo memory, are added to an AND gate, which results in obtaining neat printing signals 26 having uniform dot intervals. The wire 5 is struck with an electromagnetic excited by said print signals.
