性からパッケージが大きくなるという問題点がある。In the conventional photointerrupter described above, the light emitting element and the light receiving element are each electrically independent, so the number of leads equivalent to the total number of each electrode is required, and when operating, the same potential ends must be connected with an external circuit. In addition, there is a problem that the package becomes large because it is necessary to separate the leads by a predetermined distance, for example, 2.54 mm.
