したことを特徴とする、放電破壊式プリンタ。[Claims for Utility Model Registration] For a magnetic card in which a colored layer and a conductive layer are formed on the surface of a substrate made of a non-magnetic material, the conductive layer is grounded by pressing an earth roller against the surface of the magnetic card. While maintaining the magnetic card at a potential, a printing head formed by a discharge electrode is opposed to the surface of the magnetic card, and the conductive layer of the magnetic card is destroyed by discharge in a predetermined pattern, thereby exposing the colored layer in the discharge-destroyed area. In the electric discharge breakdown type printer, which displays the predetermined pattern, the rotary shaft of the ground roller is pivotally supported to be movable in a direction perpendicular to the surface of the magnetic card;
The rotary shaft is equipped with a conveyance roller made of an elastic material together with a ground roller, and when the magnetic card is conveyed, the earth roller of the rotary shaft is slightly separated from the surface of the magnetic card, so that only the conveyance roller is The magnetic card is conveyed by pressing against the surface of the magnetic card, and when printing on the magnetic card, the rotating shaft approaches the surface of the magnetic card, so that both the earth roller and the conveyance roller A discharge destruction type printer, characterized in that it can come into contact with the surface of the magnetic card.
