Title:
NON-CONTACT OPERATING DEVICE
Document Type and Number:
Japanese Patent JP2022131564
Kind Code:
A
Abstract:
To provide a non-contact operating device that effectively prevents a load from malfunctioning due to simultaneous detection of proximity of a detection target by a plurality of detection units.SOLUTION: A non-contact operating device according to an embodiment includes an exterior unit, a plurality of detection units, a control unit, and a shielding unit. The exterior unit has an exposed surface exposed to a space. Each of the plurality of detection units includes a light emitting unit that emits infrared rays into a space and a light receiving unit that can receive infrared rays reflected by a detection target in the space, and is installed on the exposed surface. The control unit controls the state of power supply to a load on the basis of the state of infrared rays received by each of the light receiving units. The shielding unit covers a part of the light receiving part in one or more of the plurality of detection units, and shields infrared rays from entering the light receiving unit through the covered portion.SELECTED DRAWING: Figure 1
