Abstract

An in-body image capturing device (camera unit) with high reliability is suggested. A camera unit ( 11 ) includes an image capturing unit that includes a lens ( 26 ) and a first illumination unit ( 27 a ) and is capable of being introduced into a body. The first illumination unit ( 27 a ) and the image capturing unit are housed in a casing ( 22 ) that is integrally molded with an integral light-transmitting body ( 22 x ) and an integral light shielding body ( 22 y ).

1 . An in-body image capturing device comprising an image capturing unit that includes a lens, and an illumination unit, the in-body image capturing device being capable of being introduced into a body, wherein
 the image capturing unit and the illumination unit are housed in a casing that is integrally molded with an integral light-transmitting body and an integral light shielding body,   the casing includes an illumination cover portion that covers the illumination unit, a lens cover portion that covers the lens, and a lens surrounding portion that surrounds the lens,   the illumination cover portion and the lens cover portion are configured with the light-transmitting body, and the lens surrounding portion is configured with the light shielding body, and   the lens surrounding portion has a portion that is positioned between the illumination cover portion and the lens cover portion.   
     
     
         2 . (canceled) 
     
     
         3 . The in-body image capturing device according to  claim 1 , wherein the lens surrounding portion has a light shielding wall that is positioned between the lens and the illumination unit. 
     
     
         4 . The in-body image capturing device according to  claim 1 , wherein the casing includes a laminated portion in which the light-transmitting body and the light shielding body are laminated between the illumination cover portion and the lens surrounding portion. 
     
     
         5 . The in-body image capturing device according to  claim 1 , wherein
 the casing includes a jutting portion that juts outward from a vicinity of an opening of the casing, and   the jutting portion is configured with the light-transmitting body.   
     
     
         6 . The in-body image capturing device according to  claim 1 , wherein a light irradiation direction of the illumination unit is inclined in a direction to separate from the lens with respect to an optical axis direction of the lens. 
     
     
         7 . The in-body image capturing device according to  claim 1 , wherein emboss processing is applied to an internal surface of the illumination cover portion. 
     
     
         8 . The in-body image capturing device according to  claim 6 , wherein
 in the casing, another illumination unit is housed in a position on an opposite side to the illumination unit with respect to the lens, and   a light irradiation direction of the other illumination unit is inclined in a direction to separate from the lens with respect to the optical axis direction of the lens.   
     
     
         9 . The in-body image capturing device according to  claim 8 , wherein the light irradiation direction of each of the illumination unit and the other illumination unit is inclined at 30° to 70° with respect to a lens optical axis. 
     
     
         10 . The in-body image capturing device according to  claim 1 , wherein the lens cover portion is protruded to an outside of the casing. 
     
     
         11 . The in-body image capturing device according to  claim 5 , further comprising:
 a light shielding upper cover that covers the opening of the casing, wherein   the upper cover and the jutting portion are laser-welded together.   
     
     
         12 . The in-body image capturing device according to  claim 1 , further comprising:
 an upper cover that covers an opening of the casing; and   a cable that is electrically connected with the illumination unit and the image capturing unit and is drawn out to an outside from the upper cover.   
     
     
         13 . The in-body image capturing device according to  claim 1 , further comprising:
 an upper cover that covers an opening of the casing, wherein   the upper cover is in an elongated shape, and at least one of both end portions of the upper cover is formed as a grip portion.   
     
     
         14 . The in-body image capturing device according to  claim 13 , wherein a groove is formed in at least one of an upper surface and a lower surface of the grip portion. 
     
     
         15 . An in-body monitoring camera system comprising:
 the in-body image capturing device according to  claim 1 ;   a support tube that has a connection portion with a tubular tool which is capable of being introduced into the body on one end side and has a joining portion to the in-body image capturing device on another end side;   a cable that is connected with the in-body image capturing device and passes through the support tube; and   a control system that is electrically connected with the cable.
