<p>PURPOSE:To improve the bonding strength when light emitting side and light detecting side individual element packages are inserted into a photointerrupter package case and stabilize the optoelectric transducing efficiency and avoid misoperation of equipment or the like by providing the light emitting side and light detecting side individual elements whose packages have uneven surfaces and resin which seals the light emitting side and light detecting side individual element packages in the photointerrupter package case. CONSTITUTION:Unevennesses 11a and 11b are provided on light emitting side and light detecting side individual element packages 1a and 1b. With the unevennesses, when the packages 1a and 1b are inserted into cylindrical fitting parts of a photointerrupter package case 6 and the fitting parts are filled with epoxy resin 8a and 8b, the epoxy resin is spread entirely and stays in the recessed parts of the unevennesses 11a and 11b so that the bonding strength between the individual element packages and the package case 6 can be improved. Moreover, as the individual element packages 1a and 1b are solidly fitted, the discrepancy of the focus of a light (a) or the like can be avoided and misoperation of equipment or the like can be avoided.</p> |
