Patent Images
1. A capsule endoscope comprising:
- an image capturing unit that has an image capturing section which can capture images of an inside of an abdominal cavity;
an illuminating unit that outputs light and illuminates the inside of the abdominal cavity with the light;
a power-supply unit that supplies power to the image capturing unit and the illuminating unit;
a front cover that covers the image capturing unit and the illuminating unit and is provided with an illuminating window that lets the light output by the illuminating unit to pass through and that makes it hard for the light output by the illuminating unit to be reflected toward the image capturing unit; and
a capsule casing that is attached to the front cover such that there is a watertight space inside, wherein the image capturing unit, the illuminating unit, and the power-supply unit are housed in the watertight space.

Abstract
A capsule endoscope has a front cover having a window for illuminating light and a window for capturing images. The window for illuminating light is flat. The window for capturing images is flat or convex. Because the window for illuminating light is flat, the light passes through the window without being reflected toward an image capturing unit.
