<p>PURPOSE:To standardize an external shape, and to improve productivity by detachably installing at least one of a light-emitting section and a light-receiving section to a base and disposing a plurality of lead inserting holes, into which leads for the light-emitting section and the light-receiving section mounted to or dismantled from the base are inserted, so that the space of the light- emitting section and the light-receiving section changes. CONSTITUTION:A light-emitting section 2 is fixed to a base 1, and lead inserting holes 11-15 and 16-20 are each formed in pairs. Contactors are each fastened to the lead inserting holes 11-15 and 16-20, respective contactor for the lead inserting holes 11-15 is connected in parallel, and separate contactor for the lead inserting holes 16-20 is also connected in parallel. A detachable light- receiving section 3-1 has a pair of leads 31, 32, and the leads 31, 32 are inserted into the pairing lead inserting holes 11, 16 and the light-receiving section 3-1 is fitted to the base 1, thus minimizing the space of the light-emitting section 2 and the light-receiving section 3-1. The light-receiving section 3-1 is inserted into the lead inserting holes 15, 20 and set up to the base 21, thus maximizing the space of the light emitting section 2 and the light-receiving section 3-1.</p> |
