no. 1 Embodiment approach

[0031] Such as figure 1 and figure 2 As shown, a capsule endoscope (hereinafter referred to as “endoscope”) 1 according to this embodiment houses an imaging unit 2 in a capsule casing 5 . in addition, Figure 3A and Figure 3B It is a plan view and a cross-sectional view of a part of the imaging unit 2 before being housed in the casing 5 .

[0032] In the following description, the drawings according to the embodiments are schematic. It should be noted that the relationship between the thickness and width of each part, the ratio of the thickness of each part, etc. Parts that differ in dimensional relationship and ratio to each other. In addition, illustration of some constituent elements may be omitted.

[0033] The housing 5 is composed of a cylindrical main body 5A and substantially hemispherical end caps 5B, 5C at both ends of the main body 5A. The end cover 5B is made of a transparent material, and the main body 5A and the end cover 5C are made of an integral opaque...

no. 2 Embodiment approach

[0091] Next, the imaging unit 2A of the second embodiment will be described. Since the imaging unit 2A is similar to the imaging unit 2 , the same reference numerals are assigned to the same function components and description thereof will be omitted.

[0092] That is, if Figure 9 As shown, the structure of the connection part JA is similar to the structure of the connection part J of the imaging unit 2. In addition, in Figure 9 Adhesive layers etc. are not shown.

[0093] Such as Figure 9 As shown, imaging unit 2A includes: cover glass 18 ; imaging element 10A corresponding to a first substrate; flexible substrate 70A as a first relay wiring board; and flexible substrate 80A as a second relay wiring board. The cover glass 18 is adhered to the light receiving portion 11A formed on the imaging element 10A with an adhesive resin. A cover glass 18 made of transparent glass protects the light receiving unit 11A. The external electrodes 19 connected to the imaging element 1...

Abstract

An imaging unit 2 includes: a first substrate 10 on which an imaging element 11 is mounted; a first relay wiring board 70 including a first wire 73 which is electrically connected at one end thereof to the first substrate 10 and has a first electrode pad 73A at another end thereof; a second substrate 20 on which an electronic component 21 is mounted; and a second relay wiring board 80 including a second wire 83 which is electrically connected at one end thereof to the second substrate 20 and has a second electrode pad 83A at another end thereof. The first electrode pad 73A and the second electrode pad 83A which are in close contact with each other and thus fixed to each other in an electrically connected state are deformed by being bent.

Description

technical field [0001] The present invention relates to an imaging unit in which a first substrate on which an imaging element is mounted and a second substrate on which electronic components are mounted are electrically connected via a first relay wiring board and a second relay wiring board, and a capsule-type internal A speculum and a method of manufacturing the capsule endoscope. Background technique [0002] Capsule-type endoscopes with imaging functions and wireless transmission functions are in the stage of popularization. Capsule-type endoscopes move through the stomach, small intestine, and other digestive tracts with peristaltic motion from the moment they are swallowed by the subject to their natural excretion, and use the imaging function to photograph the interior of organs. [0003] During movement in the alimentary canal, the image captured by the capsule endoscope is transmitted as an image signal to an external device provided outside the subject through a ...
