Problems solved by technology

[0012] In addition, in the technique of Patent Document 3, there is also a problem that since a glass cover with a large outer diameter is used to secure a space for connecting the imaging element and the flexible substrate, sufficient reduction in diameter cannot be achieved, and the The use of optical components for fitting with the lens frame and securing space for the connection of the imaging element and the flexible substrate increases the length of the hard part at the tip of the optical component.

Embodiment Construction

[0046] In the following description, an endoscope apparatus having a camera module will be described as a mode for carrying out the present invention (hereinafter referred to as “embodiment”). Also, the present invention is not limited to this embodiment. In addition, in description of drawings, the same code|symbol is attached|subjected to the same part. In addition, it should be noted that the drawings are schematic, and the relationship between the thickness and width of each member, the ratio of each member, and the like are different from actual ones. In addition, parts from which dimensions or ratios differ between drawings are also included.

[0047] figure 1 It is a diagram schematically showing the overall configuration of an endoscope system according to an embodiment of the present invention. Such as figure 1 As shown, the endoscope device 1 has an endoscope 2 , a universal cable 6 , a connector 7 , a light source device 9 , a processor (control device) 10 , and...

Abstract

Provided are a compact imaging device and endoscope device. The imaging device (35) is provided with: an optical member holder (36) that is hollow with both ends being open, and has a notched section (36c) at the side surface at one end; an objective lens (43) that is installed within the optical member holder (36) and that focuses light entering from the other end of the optical member holder (36); a prism (37) that is installed within the optical member holder (36) and that reflects light focused by the objective lens (43); an imaging element (38) that receives the light reflected by the prism (37) and that generates an electrical signal by means of performing photoelectric conversion; and a substrate (39) that is electrically connected to the imaging element (38). The prism (37) is characterized by at least a portion of the outer peripheral surface thereof forming a cylindrical surface, the cylindrical surface contacting the interior of the optical member holder (36), and at least a portion of the imaging element (38) being attached to the side surface of the optical member holder (36) via the notched section (36c).

Description

technical field [0001] The present invention relates to an imaging device and an endoscope device that are installed at the tip of an insertion portion of an endoscope inserted into a subject to image the subject. Background technique [0002] Conventionally, endoscope apparatuses have been widely used for various inspections in the medical and industrial fields. Among them, in a medical endoscope apparatus, by inserting a flexible and slender insertion portion having an imaging device built in at a distal end portion into a body cavity of a subject such as a patient, observation of a subject site can be performed, Furthermore, the treatment tool can be protruded from the front end of the insertion part to perform treatment as needed, so it is widely used. [0003] In recent years, due to the expansion of the light-receiving area and the increase in the size of the imaging element due to the mounting of the processing circuit, the following imaging module has been proposed ...
