Abstract
An endoscope apparatus includes: an image pickup device; a glass lid that is provided on a distal end side ahead of a light receiving surface of the image pickup device and is fixed to a front face of the image pickup device in an integrated manner; and a frame body that covers at least a part of the image pickup device and the glass lid. The frame body includes a fixing region for fixing an image pickup circuit portion provided on a proximal end side opposite to the front face of the image pickup device, and a non-fixing region that keeps the distal end side relative to the light receiving surface of the image pickup device and the glass lid fixed to the light receiving surface of the image pickup device in a non-fixed state.
Claims10
An endoscope apparatus comprising:
- an image sensor;
- a device front-side optical member provided on a distal end side ahead of a light receiving surface of the image sensor, the device front-side optical member being fixed to a front face of the image sensor in an integrated manner;
- a frame that covers at least a part of the image sensor and covers at least a part of the device front-side optical member;
- a circuit board provided on a proximal end side of the image sensor, the proximal end side being opposite to the front face of the image sensor;
- and
- an adhesive for fixing the circuit board to the frame;
- wherein a gap is formed between the frame and a side surface of the image sensor and between the frame and a side surface of the device front-side optical member;
- and
- the gap does not include a fixing member disposed therein such that the frame and the side surface of the device front-side optical member are not directly fixed to each other.
