<p><P>PROBLEM TO BE SOLVED: To provide a reflective photosensor provided with light shielding structure preventing malfunction and improving detection accuracy by surely preventing light leakage generated between a light emitting member and a light receiving member arranged on a substrate. <P>SOLUTION: The reflective photosensor 21 is provided with: the substrate 22 on which an electrode pattern and an external connection terminal 27 are formed; a light emitting diode 23 and a photo IC 24 arranged on the substrate 22; and an inwall 25 formed between the light emitting diode 23 and the photo IC 24. A grooved recess 28 dividing the light emitting diode 23 and the photo IC 24 from each other is formed on the surface of the substrate 22, and the lower end of the inwall 25 is engaged with the inside of the recess 28. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
