Abstract
A proximity printing device in which the angle of the light with which a workpiece is irradiated can be changed has an exit part attached on a base and a light source part supported by two bearings. Light emitted from a lamp is focused by an oval focusing mirror and is radiated onto the workpiece via a mask. In one embodiment, two ends of the base are joined to guides of arc-shaped arms. Rotating the base tilts the exit part and the workpiece can be obliquely irradiated with light. Because the light source part is held by two bearings, the lamp of the light source part can be held in a vertical state even when the base is tilted. Furthermore, the direction of motion of the light source part can be limited by means of a ball spline or the like to a horizontal direction, and can be moved by means of a drive so that the exit part can be tilted while holding the light source part vertical.
