Abstract
Official abstract text for this publication.
A near-infrared sensor cover includes a cover body that is transmissive to near-infrared light. The cover body includes a base, a hard coating layer, a heater, and an anti-reflection layer. The base is formed from a transparent resin material. The hard coating layer is formed at a front of the base in a transmission direction of near-infrared light and has a greater hardness than the base. The heater is formed at a rear of the base in the transmission direction and formed by a linear heating element that generates heat when energized. The anti-reflection layer is formed at a rear of the heater in the transmission direction to limit reflection of near-infrared light.
First claim
Opening claim text (preview).
What is claimed is: 1 . A near-infrared sensor cover configured to cover a transmitter and a receiver of near-infrared light in a near-infrared sensor, the near-infrared sensor cover comprising: a cover body that is transmissive to near-infrared light, wherein the cover body includes a base formed from a transparent resin material, a hard coating layer formed at a front of the base in a transmission direction of near-infrared light and having a greater hardness than the base, a heater formed at a rear of the base in the transmission direction and formed by a linear heating element that generates heat when energized, and an anti-reflection layer formed at a rear of the heater in the transmission direction that limits reflection of near-infrared light. 2 . The near-infrared sensor cover according to claim 1 , wherein the base includes a front base and a rear base arranged at a rear of the front base in the transmission direction, and the near-infrared sensor cover further comprises: a decorative layer arranged between the front base and the rear base, wherein the decorative layer is transmissive to near-infrared light. 3 . The near-infrared sensor cover according to claim 1 , further comprising: an undercoat layer formed between the base and the heater, wherein the undercoat layer is transmissive to near-infrared light, and the heater is in tight contact with the base via the undercoat layer. 4 . The near-infrared sensor cover according to claim 1 , further comprising: a protective film formed between the heater and the anti-reflection layer, wherein the protective film is transmissive to near-infrared light, and the heater is covered by the protective film from rearward in the transmission direction.
