PURPOSE:To provide a printer of less noise capable of performing simultaneous printing by such an arrangement wherein an impact head and a non-impact head are arranged in the same mechanical unit and a character generator and a drive power source are commonly used for both heads. CONSTITUTION:A printer is composed of an impact head capable of printing characters and image elements on a print medium by utilizing dynamic energy produced by an electromagnet 3 and a non-impact head arranged in the same mechanical unit wherein said impact head is arranged which is driven by a character generator and a drive power source 11 of said impact head. A power supply terminal 11a is connected to B by a switch 12, pulse signal is given through an input terminal, causing a switching element 10 to become ON condition, and in turn, causing the heat sensitive element of a thermal head 7 to generate heat. For example, pulse signals supplied from an input terminal 9 cause the switching element 10 to become ON for a period of 0.8ms and become OFF for a period of 0.8ms. EFFECT:A proper print head can be freely selected and used according to the use. |
