Patent ID: 7858919

Claim:
A photo reflector including a light-emitting element and a light-receiving element, comprising: a circuit board; the light-emitting element being disposed on and electrically connected to the circuit board, the light-emitting element being configured to emit light toward an object to be detected; the light-receiving element being disposed on and electrically connected to the circuit board, the light-receiving element being configured to receive the light after the light is reflected on the object, the light-emitting element and the light-receiving element being disposed side by side with an interval between the light-emitting element and the light-receiving element; a first light-transmitting resin sealing the light-emitting element and including an upper surface as a light-emitting surface and peripheral side surfaces; a second light-transmitting resin sealing the light-receiving element and including an upper surface as a light-receiving surface and peripheral side surfaces; a light-shielding member provided in contact with the first light-transmitting resin and the second light-transmitting resin; and a light-intensity adjuster provided on the upper surface as the light-receiving surface of the second light-transmitting resin, and the light-intensity adjuster disposed in an optical path of the light that is emitted from the light-emitting element toward the object, and redirected toward the light-receiving element after being reflected on the object.
