Abstract
An optical sensor includes a light source, a light receiver, and a convex portion. The light source emits light to an object. The light receiver receives reflected light of the emitted light reflected by an object and generates a signal showing a light reception result. The convex portion has a height higher than a height of the light source and the light receiver. The convex portion is between the light source and the light receiver to block reflected light from the light receiver when light from the light source is reflected within a range of a predetermined distance from the convex portion. The light receiver outputs a signal to show a light reception result of equal to or less than a threshold amount of light indicating that the reflected light is not received in response to proximity of the object being within a range of a predetermined distance.
