Abstract
PURPOSE: To ensure an accurate positioning between the light emitting element and the photo detector to each other as well as to facilitate an easy assembling by providing the opposite projection part to the case storing the light emitting element and the photo detector, opening both the opposite side face and the lower edge side face, and inserting the ambient unit of the elements and the base containing the lead frame into the above mentioned faces.
CONSTITUTION: Ambient unit 17 to which light emitting element 18 or photo detector 19 is set is positioned so that condenser lens part 22 may be set at light transmission window 12, and then held by a pair of projection bars 13 and 14 to be mounted onto base 11. Then notch parts 28 provided to a pair of lead frames 26 and 27 are inserted into lead frame mounting projections 15 and 16 each and then mounted onto base 11. After this, base 11 thus structured is fitted into two opposing projection parts 30 and 31 provided to case 29 through lower edge open part 33. In this way, element 18 and detector 19 can be fixed to the case in opposition to each other, thus ensuring a high-accuracy positioning.
