Problems solved by technology

However, in conventional endoscope devices, if the image sensor that can be mounted in the insertion part is to be provided as a high-quality and large-scale image sensor, hard parts including signal lines and the like connected to the image sensor are required. The size also increases, the insertion part has a large diameter, or the length of the hard part of the insertion part becomes longer.

Abstract

An imaging mechanism and an endoscope apparatus include: an image sensor including a sensor face and a plurality of input / output leads, a holding member having a sensor contact face contacted with one face of an opposite side of the image sensor to the sensor face, a circuit board that is secured to an outer face of an opposite side of the holding member to the sensor contact face and has a mounting surface in parallel to the sensor face, and a contact-point part disposed on a side face of the circuit board intersecting with a mount face, and in a region where the outline of the circuit board is inside the outline of the holding member. At least one of the holding member and the circuit board includes a relay wiring part which the contact-point part and at least one of the input / output leads are electrically connected to.

Description

technical field [0001] The invention relates to an imaging mechanism and an endoscope device. Background technique [0002] Conventionally, it is known to insert an endoscope apparatus into the inside of the object to be observed when observing the inside of the object to be observed. For example, there is known an endoscope device having a vertically long insertion portion, the insertion portion has a distal end and a proximal end, and an imaging device for imaging an object is arranged at the distal end of the insertion portion. mechanism. [0003] As an example of such an imaging mechanism, Japanese Unexamined Patent Publication No. 2006-68058 discloses a distal end portion of an electronic endoscope. In the electronic endoscope described in Japanese Unexamined Patent Application Publication No. 2006-68058, a substrate on which a solid-state imaging element (image sensor) is mounted and a signal line electrically connected to the image sensor are sealed inside a resin a...
