Image sensor
First Claim
1. An image sensor comprising:
- an illumination part for illuminating a subject;
a lens part for forming an optical image of the subject;
an imaging part for generating an image based on the optical image; and
a housing for accommodating the illumination part, the lens part, and the imaging part,wherein a cover member covering a front side of the lens part and the illumination part is attached to the housing, the cover member is light-transmissive, and a wall member partitioning a space where the lens part is arranged and a space where the illumination part is arranged is provided inside the housing, andthe housing has a heat transfer structure for transferring heat generated inside the housing to the cover member,wherein the housing comprises a case member made of metal,the case member is in contact with a heating body present inside the housing directly or via a heat conduction member, and the case member is in contact with the cover member directly or via a heat conduction member, so as to form the heat transfer structure,wherein the case member comprises a plurality of members comprising a first member and a second member which are separable, anda first sealing member is provided in between the first member and the second member for sealing a gap between the first member and the second member, and a first contact part at which the first member and the second member are in direct contact is formed,wherein the cover member is fixed to the second member,wherein a second sealing member is provided for sealing a gap between the second member and the cover member, and a second contact part at which the second member and the cover member are in direct contact is formed,wherein the cover member is screw-fixed to the second member,the second sealing member is provided closer to a center of the cover member than a screw fixing position where the cover member is screw-fixed to the second member, and the second contact part is further formed closer to the center of the cover member than the second sealing member.

Abstract
The disclosure provides a structure for suppressing occurrence of dew condensation on a cover member in an image sensor for industrial use. An image sensor includes an illumination part for illuminating a subject, a lens part for forming an optical image of the subject, an imaging part for generating an image based on the optical image, and a housing for accommodating the illumination part, the lens part, and the imaging part. A light-transmissive cover member covering a front side of the lens part and the illumination part is attached to the housing. A wall member partitioning a space where the lens part is arranged and a space where the illumination part is arranged is provided inside the housing, and the housing has a heat transfer structure for transferring heat generated inside the housing to the cover member.
