PURPOSE:To always obtain a good printing state by preventing the evaporation of ink, by forming a cap, which blocks the leading end part of the recording electrode provided to the front surface of a printer head from the open air, into a flat plate shape. CONSTITUTION:A carrier 3 is attached to two horizontal guide shafts 2 provided to a printer main body 1 in a state freely reciprocally moving to the left and right and a printer head 4 is arranged to said carrier 3. The opposed electrode 5 opposed to the head 4 is horizontally attached to the central part of the printer main body 1 and a tractor 7 for feeding recording paper 6 is provided behind the opposed electrode 5. An operation knob 8 is connected to the tractor 7. In this constitution, because no current is supplied to a solenoid 23 at the time of non-printing, a movable iron core 24 is pushed up by the force of a spring 25 and the closing surface of a cap 26 blocks the leading end part 15 of the recording head 16 from the open air to prevent the evaporation of ink 11. Therefore, the state of the leading end part 15 of the recording electrode 16 is always kept constant and a stable printing state is obtained. |
