２に記載の放電破壊式プリンタ。[Claims for Utility Model Registration] (1) By pressing an earth roller onto the surface of a magnetic card having a colored layer and a conductive layer formed on the surface of a substrate made of a non-magnetic material, The conductive layer of the magnetic card is held at ground potential, and 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 the shape of a predetermined pattern, thereby coloring the area destroyed by discharge. In an electrical discharge rupture printer that exposes a layer and thereby displays the predetermined pattern, the surface of the earth roller that is to be brought into contact with the magnetic card is formed to have concavities and convexities in the axial direction. A discharge-destructive printer characterized by: (2) The electrical discharge destruction type printer according to claim 1, wherein a cleaning plate is brought into contact with the surface of the ground roller. (3) The electrical discharge breakdown type printer according to claim 1 or 2, wherein the surface of the earth roller is plated with a platinum group element such as rhodium, ruthenium, or palladium.
