A circuit board 1 provided with terminal receiving holes 6 is to be provided with components. The component positions are visually indicated to the assembler by a display device. A light spot is traced rapidly in a pattern characterising each component and positioned to indicate the relevant holes 6 in accordance with a predetermined assembly program. image patterns such as 2', 3' or 4' may be achieved. The image is traced sufficiently frequently that the assembler perceives a static image. <IMAGE> |
