Abstract
There is provided a limited-area reflection type optical sensor having an emitted light lens and a reflected light lens. An opposite-light-receiver-side portion opposite to a light receiver side constitutes a first curvature surface having a first curvature while a light-receiver-side portion on the light receiver side with respect to the opposite-light-receiver-side portion constitutes a second curvature surface having a second curvature smaller than the first curvature in the emitted light lens provided in an optical path of the emitted light. An opposite-light-emitter-side portion opposite to a light emitter side constitutes a fourth curvature surface having a fourth curvature while a light-emitter-side portion on the light emitter side with respect to the opposite-light-emitter-side portion constitutes a fifth curvature surface having a fifth curvature smaller than the fourth curvature in the reflected light lens provided in an optical path of the reflected light.
