Abstract

An animal avoidance device 10 according to the present invention is a device which an animal avoids and which is suitable for miniaturization and is provided with a new mechanism that displaces a light irradiation region irradiated with light from a light collection part, the animal avoidance device being provided with: a light source 11 that radiates laser light L; and a diffraction lattice 12 that changes the propagation direction of the laser light L radiated from the light source 11, wherein the relative position of the diffraction lattice 12 to the light source 11 is changed, thereby changing, on a floor surface F which is to be irradiated, the position of a light irradiation region SP1 irradiated with the laser light L that has passed through the diffraction lattice 12.

IPC Classes  ?

• A01M 29/10 - Scaring or repelling devices, e.g. bird-scaring apparatus using visual means, e.g. scarecrows, moving elements, specific shapes, patterns or the like using light sources, e.g. lasers or flashing lights
• G02B 5/18 - Diffracting gratings

Abstract

This indoor pest repellent device (10) is provided with: a light source (11); a light concentrating part (the first light concentrating part (13)) which concentrates a portion of diffused light (LS) emitted from the light source (11); and a first displacement unit (the rotation mechanism (14)) which changes the relative position of the first light concentrating part (13) relative to the light source (11), and which displaces the irradiation region (the light irradiation region (SP1)) of the light from the first light concentrating part (13), said irradiation region being formed on a floor. The light concentrating part is provided with a convex lens.
