Assembling method of capsule medical apparatus
First Claim
1. An assembling method of a capsule medical apparatus including a sealed capsule having a cylindrical casing with a central axis, an illuminating unit, an image pick-up unit for picking up an image of a portion illuminated by the illuminating unit, and an objective optical system for focusing an image on the image pick-up unit through an optical path of the objective optical system, wherein the objective optical system is attached to a fixing frame, the assembling method comprising:
- displaying an image area of the image pick-up unit and establishing one or more reference positions thereon in order to locate a center position of said image area;
displaying an image of the fixing frame and overlapping the image of the fixing frame with the image area of the image pick-up unit;
positioning the fixing frame such that the center position of the image area of the image pick-up unit coincides with the center position of the image of the fixing frame, the optical path of the objective optical system, and the central axis of the cylindrical casing; and
a fixing step after the positioning step wherein the image pick-up unit and the fixing frame are attached and made to be fixed in position with respect to each other.

Abstract
An assembling method of a capsule medical apparatus is provided. The capsule medical apparatus includes a sealed capsule container having an image pick-up unit which picks up an image of a portion illuminated by an illuminating unit, and an objective optical system which is arranged in front of the image pick-up unit. The assembling method includes a positioning step of positioning so that a relative position of a reference position of a fixing frame in the objective optical system matches a reference position of an image area of the image pick-up unit, and a fixing step of, after the positioning step, contacting a reference down-surface of the fixing frame with the top surface of the image pick-up unit and fixing the image pick-up unit and the fixing frame.
