PURPOSE:To perform assembly of a component board with good efficiently with no wiring assembly chart by providing an optical indication means optically indicating terminal insertion holes inserting terminals of the prescribed component in the prescribed positions of a component board. CONSTITUTION:A plurality of component insertion indication switches 2 of a push button type for inputting the component insertion indication and a plurality of light-emitting diode groups 3 emitting light according to this indication input are provided on a base stand 1 and a component board 5 having large number of terminal insertion holes 4 in the prescribed positions thereon is placed. Thereby, when, for instance, an indication switch 2 of the number 11 turns ON, the terminal insertion holes 4 of the component board 5, into which the terminal of electric component of the number 11 are to be inserted, are shone visible by irradiation light from below of a light-emitting diode 3 so that assembly of the component is facilitated by inserting the electric component of the number 11 are inserted thereinto. |
