An apparatus including a dot matrix transfer head that includes an impact wire housing. A plurality of impact wires are disposed within the impact wire housing and extend out of the impact wire housing. A splaying element attached to a bottom surface of the impact wire housing. The plurality of impact wires extend into and through the splaying element. A guide head attached to a bottom surface of the splaying element. The guide head includes multiple holes that arrange the plurality of impact wires in a matrix configuration. The splaying element is designed to direct the plurality of impact wires toward the multiple holes in the guide head.

An application unit includes an application material container to contain an application material, and an application needle to apply, to a target surface, the application material contained in the application material container. A first hole is formed in a bottom of the application material container, and a second hole is formed in an upper lid of the application material container. The application needle is configured to be movable along a line passing through the first hole and the second hole. A third hole is formed in a part of the application material container for allowing air to pass through the third hole, or a lowermost end of a wall of the first hole has a chamfer.
