PURPOSE:To instruct directly the assembling position of parts and to reduce assembling errors by irradiating selectively spot-like light according to models and specifications to the position on a working table or base material where the parts are to be assembled. CONSTITUTION:Many seats 1a for assembling parts are projected atop an assembling jig 1 of a working table. Spot lights 2 of the same number as the number of the seats 1a are installed above the jig 1. The lights 2 are so formed that each thereof can irradiate each of the seats 1 by spot-like light 2a. The lights 2 are connected to a selective control device which selects the lights 2 to irradiate and instruct the seats 1a to be disposed with parts 3. Phototubes or laser light may be used for the lights 2 and means consisting of convex lenses fitted to punched holes are also usable in obtaining the spot-like light. |
