Abstract: A toner density sensor includes: a light emitting element configured to radiate light; a light receiving element configured to receive the light emitted from the light emitting element and reflected from a detection object; a substrate whereon the light emitting element and the light receiving element are surface mounted; a case covering the light emitting element and the light receiving element; an optical path configured parallel to the substrate for light generated from the light emitting element; a groove provided in the substrate from the end part of the substrate in the direction light travels from the light emitting element to between the light emitting element and the light receiving element, the groove recessed from the mounting surface in the thickness direction of the substrate; and an insert provided to the case and configured for insertion into the groove.

Abstract: To effectively concentrate particles in a detection area serving as the measurement center of a sensor. A particle sensor is provided with an enclosure; a detection area inside the enclosure, and a guide path in the enclosure, configured to guide a gas to a detection area. The cross-sectional perimeter in a direction perpendicular to the extending direction of the guide path gradually becomes smaller from an inlet to the guide path toward the detection area.

Abstract: A push button switch includes a push button, a movable contact that moves together with the push button, and a fixed contact with respect to which the movable contact comes into contact or separates in accordance with the operation of the movable contact. The push button switch includes a light emitting element, and a light receiving element. A light emitting position where light emitted from the light emitting element is radiated to the outside, and a light receiving position where light detected by the light receiving element is received from the outside are disposed outward of an edge of the push button when viewed in a pushing direction. The light receiving element is disposed to detect light emitted from the light emitting element and reflected by an object in a detection region set in a space on the push button side in the opposite direction to the pushing direction.

Abstract: A push button switch 1 comprises: a push button 10 that can be pushed in; a movable contact 120 that is linked to the push button 10; and a fixed contact 121 that comes into contact with or separates from the movable contact 120 by operation of the movable contact 120. The push button switch 1 further comprises a light-emitting element 130 for emitting light, and a light-receiving element 131 for detecting light. The light-receiving element 131 is disposed so as to detect the light emitted from the light-emitting element 130 and reflected by an object within a prescribed region. The push button switch 1 outputs an ON signal if the push button 10 has been pushed in, thereby causing the movable contact 120 to come into contact with the fixed contact 121, or if it is determined that the light-receiving element 131 has detected light reflected by an object.
