Abstract

PURPOSE:To prevent making of breaks in character printing and improve character printing quality by using an LED unit disposed zigzag with LED array chips. CONSTITUTION:Since LED array chips 15 are disposed zigzag in such a way that the pitch P between the LEDs in the chips 15 and the distance P' in the printing direction on the side end of the adjacent chips 15 assume the same value, good character printing quality is obtained without producing any breaks in character printing.
