PROBLEM TO BE SOLVED: To reduce in size and cost the apparatus and to improve operability by disposing an optical fiber at a light emitting element placing side of a substrate, and constituting to confirm lighting of the element via the fiber. SOLUTION: When compressed air is supplied to a drive unit 11, a slide plate 7 coupled to the unit 11 is moved toward a base 4, and a probe 10 is brought into contact with a substrate 1. Then, a voltage is supplied via the probe 10, a light emitting element 2 can emit light, and a liquid crystal display element 3 becomes operable to display. A light emitted from the element 2 is incident to an incident end of an optical fiber 5, emitted from its emitting end, and arrived at an operator A. At this time, the emitting end of the fiber 5 is disposed near the element 3. Thus, the operator A can substantially simultaneously conduct confirmation of lighting of the element 2 and display state confirmation of the element 3 in a same visual field. |
