Abstract
A proximity sensor detects an object to be detected. The proximity sensor includes a board; at least three light emitting portions which are mounted on a surface of the board such that not all the light emitting portions is arranged on a straight line, and which emits light; and a light receiving portion which is mounted on the surface of the board so as to have a predetermined positional relationship with the three light emitting portions, and which receives reflected light derived from light emitted from the light emitting portions and reflected by the object to be detected.
Claims8
A proximity sensor for detecting an object to be detected, comprising:
- a board;
- at least three light emitting portions which are mounted on a surface of the board such that not all the light emitting portions is arranged on a straight line, and which emits light;
- and
- a light receiving portion which is mounted on the surface of the board so as to have a predetermined positional relationship with the three light emitting portions, and which receives reflected light derived from light emitted from the light emitting portions and reflected by the object to be detected,
- wherein the at least three light emitting portions and the light receiving portion are respectively mounted in recess portions formed in the surface of the board,
- wherein a plating layer is formed on an inner wall of each of the recess portions in which the light emitting portions are mounted, the plating layer forming a reflecting part, and
- wherein a light emitting portion mounting part, on which a light emitting portion is mounted, and the reflecting part are integrally formed in each of the recess portions in which the light emitting portions are mounted.
A proximity sensor for detecting an object to be detected, comprising:
- a board;
- at least three light emitting portions which are mounted on a surface of the board such that not all the light emitting portions is arranged on a straight line, and which emits light;
- and
- a light receiving portion which is mounted on the surface of the board so as to have a predetermined positional relationship with the three light emitting portions, and which receives reflected light derived from light emitted from the light emitting portions and reflected by the object to be detected,
- wherein the at least three light emitting portions and the light receiving portion are respectively mounted in recess portions formed in the surface of the board, and
- wherein each of the recess portions in which the at least three light emitting portions are mounted has an opening portion deformed toward outside relative to the light receiving portion, such that light emitted from the light emitting portion is directed toward the outside.
