PURPOSE:To make a surface sheet material available for a duplicate original by striking a recording medium from above the surface sheet material by an impact printer. CONSTITUTION:A recording medium composed of a surface sheet material and a transparent sheet material in a lapped state is struck by an impact printer from above the surface sheet material. For the surface material sheet, it is required to have a flexibility as high as the impact of a stroke when an image is formed by a hammer or wire of the impact printer from above the surface sheet material can be transmitted to the transparent sheet material through the surface sheet material. Therefore, an image is printed on the surface sheet material and simultaneously formed on the transparent sheet material by a single stroke. In this manner, the surface sheet material intact is available for a duplicate manuscript. |
