摘要: To achieve an opto-reflector in which a distance to a detection target is shortened to be able to detect the position of the closer detection target, and thereby contributing to the reduction of the arrangement space. The opto-reflector (10) includes a plate-shaped substrate (11); a light emitting element (13) and a light receiving element (14) mounted on the substrate (11); light transmitting resin layer (12) which seals the light emitting element (13) and the light receiving element (14); and a light shielding portion (21) provided between the light emitting element (13) and the light receiving element (14). The light shielding portion (21) is formed at a height such that a part of light beam can be directly transferred between the light emitting element (13) and the light receiving element (14) via the light transmitting resin layer (12).

摘要: An ultrasonic sensor in the invention includes an ultrasonic transmitter, an ultrasonic receiver, and a detector. The ultrasonic transmitter transmits pulse-shaped ultrasonic waves to a thin plate to excite the thin plate. The ultrasonic receiver receives direct waves and reflected waves among the ultrasonic waves propagating in the thin plate excited by the pulse-shaped ultrasonic waves, the direct waves propagating only in the thin plate, and the reflected waves radiating outward, then reflected by the object, and returning to the thin plate. The detector detects the object present near the thin plate on the basis of a difference between a time at which the ultrasonic receiver receives the direct waves and a time at which the ultrasonic receiver receives the reflected waves.

摘要: A contactless switch device including a reflected signal acquisition unit that acquires a reflected signal of a Doppler radar or a distance measurement radar, an approach and recede detection unit that detects an approach and a recede of a target based on the reflected signal, a target identification unit that identifies the target as a hand waving left and right, up and down, or back and forth, or a thing other than the hand based on a repeated pattern of the approach and the recede of the target, and a switch control unit that executes on-and-off controls on a switch-controlled object based on whether the target is the hand waving left and right, up and down, or back and forth, or the thing other than the hand.
