Abstract

In an endoscope apparatus in which an imaging element (39)and a circuit board (40) to which the imaging element (39) is connected are provided inside a distal end of an insertion part (11), disconnection between the circuit board and a signal wiring line (42) is prevented. In an endoscope apparatus including an insertion part to be inserted into the body, an imaging element, a circuit board electrically connected to the imaging element and arranged parallel to the longitudinal direction of the insertion part, and a signal wiring line electrically connected to the circuit board and extending in the longitudinal direction are provided within the insertion part, and a connecting portion between the circuit board (40) and the signal wiring line (42)is provided with a easing member (50) that eases a force applied to the connecting portion.

Description

technical field [0001] The present invention relates to an endoscope device having an insertion portion inserted into a body, and more particularly to a wiring connection structure inside a front end of the insertion portion. Background technique [0002] Conventionally, endoscope systems for observing tissues in body cavities have been known. Electronic endoscope systems that capture normal images of the observed portion in body cavities with an imaging element and display the normal images on a monitor screen are now being developed. been widely used. [0003] The above-mentioned endoscope system has an insertion portion inserted into the body. In addition, a bending portion is provided near the front end of the insertion portion, and the bending portion is bent in any one of the up, down, left, and right directions by rotating the operation knob provided on the hand-held operation portion of the endoscope main body. Thereby, insertion into the patient's body can be made...
