Abstract: A tactile and proximity sensor includes a light source, a light receiving section, and a cover. The light source emits light. The light receiving section receives light and generates a signal providing a result of the received light. The cover includes an elastic body that deforms under external force and that covers the light source and the light receiving section. The cover includes a reflective section that reflects light between the light source and the light receiving section and a transmission section that allows light to pass through in a first direction from the light source and that allows light to pass through in a second direction from the light receiving section.

Abstract: A sensor device includes a substrate, a force sensor on the substrate, and a proximity sensor including light emitting elements on the substrate and light receiving elements to receive light from the light emitting elements. At least one of the light emitting elements and the light receiving elements of the proximity sensor is located at three or more positions that surround the force sensor on the substrate. A position of a center of gravity with respect to the three or more positions is within a range in which the force sensor is positioned on the substrate.

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.

Abstract: An optical sensor includes a light emitter to emit light, a light receiver to receive the light emitted from the light emitter, a first resin body that covers the light emitter and the light receiver to transmit the light emitted from the light emitter to emit the light outside, and a second resin body that seals the light emitter and the light receiver, in which the second resin body is included inside the first resin body, and the second resin body is harder than the first resin body.
