Imaging apparatus
First Claim
1. An imaging apparatus for illuminating an illumination light by way of an observation hole formed at the top end of an imaging head from the inside of the hole to an object to be observed and focusing images of the object taken by way of the observation hole by a lens and then picking-up the same by an imaging device disposed to an apparatus body, wherein the lens is disposed being arranged on an optical axis identical with the imaging device to the apparatus body, the imaging head is mounted exchangeably to the apparatus body so as to cover the lens, and a light emission portion of an illumination system is disposed to the imaging head for illuminating a light to the object along a predetermined illumination direction and at a predetermined illumination position.

Abstract
An illumination system previously determined for an illumination direction and an illumination position to an object to be observed is disposed to an imaging head, while a lens 4 is disposed to an apparatus body, so that the number of parts for the imaging head mounted to an apparatus body can be reduced, precision fabrication such as alignment of lens optical axis is no more necessary upon manufacture of the imaging head and optimum illumination can be illuminated in accordance with the magnification ratio or the object to be observed by merely exchanging the imaging head, illumination light optimal to the magnification ratio or object to be observed can be obtained with no provision of various kinds of expositive lens units.

5. An imaging apparatus for illuminating an illumination light by way of an observation hole formed at the top end of an imaging head from the inside thereof to an object to be observed, focusing images of the object intaken by way of the observation hole by a lens and picking-up the same by an imaging device disposed to an apparatus body, wherein
a lens holder for positioning the lens on the optical axis identical with the imaging device is detachably mounted to the apparatus body, the imaging head is mounted exchangeably to the lens holder and a light emission portion of an illumination system for illuminating a light along the predetermined illumination direction and at a predetermined illumination position to the object is disposed to the imaging head.
