The dry printing apparatus comprises a housing defining a handle portion, a dry printing unit mounted to an open lower end of the housing, an air convection passage, and a guide member. The air convection passage extends through a space between the dry printing unit and side walls of the housing as well as through openings in a top wall of this housing. Convection air flows through the air convection passage to prevent the handle portion from being heated by the dry printing unit. The guide member is telescopically mounted in the open lower end of the housing between extended and retracted positions and is spring-biased toward the extended position. In operation, the guide member is applied to the surface to be dry printed and pressure is manually applied to the handle portion to telescopically move the housing and dry printing unit about the guide member until the dry printing unit reaches the surface to be dry printed. The guide member may comprise a tubular member or a generally rectangular windowed bottom plate telescopically mounted in the housing. |
