| 摘要 | An optical detection device includes a light emitting element, a light receiving element, a housing including a first aperture and a second aperture, wherein light emitted from the light emitting element reaches the light receiving element through the second aperture after passing through the first aperture and being reflected by an irradiated surface, and a slope provided in the housing and inclined in an array direction of the light emitting element and the light receiving element, as viewed in a normal direction of the irradiated surface, wherein the slope is provided at a portion on an upstream side of the first aperture in an emission direction of light from the light emitting element, the portion faces the light emitting element in the array direction, and light emitted from the light emitting element enters the portion. | ||

| 主权项 | 1. An optical detection device, comprising: a light emitting element being positioned by being mounted on a substrate; a light receiving element; a housing including a first aperture through which light emitted from the light emitting element passes and a second aperture which is different from the first aperture and through which light to be received by the light receiving element passes, and enclosing the light emitting element and the light receiving element, wherein light emitted from the light emitting element reaches the light receiving element through the second aperture after passing through the first aperture and being reflected by an irradiated surface; and a slope provided in the housing and inclined in a direction orthogonal to an array direction of the light emitting element and the light receiving element, as viewed in a normal direction of the irradiated surface, wherein the slope is provided at a portion on an upstream side of the first aperture in an emission direction of light from the light emitting element, the slope faces the light emitting element in the array direction, and light emitted from the light emitting element enters the slope. | ||
