2. Description of the Related Art Observation devices are disclosed in, for example, Japanese Patent Application Laid-Open No. 1-308527, Japanese Patent Application No. 1-26462, and Japanese Patent Application No. 1-273419. These observation devices consist of an objective tool equipped with a light source for illuminating the object to be observed, and an observation device main body including a display. It is designed to be remotely reproduced and observed, and requires stand-free observation, in other words, the observation device itself needs to be fixed in a predetermined state like a conventional microscope. In contrast to observation in which a sample of an object processed in a format is set and observed, stand-free observation can be performed in which the objective tool is held by hand to the object to be observed and the object is observed as it is. For example, 50 times to 1000 times, anyone can easily do it without any skills or expertise.
It is possible to perform magnified observation at a high magnification of 2.5 times.

Regarding an observation device consisting of an objective that captures an image of the object and a main unit that processes the image information captured by the objective, the objective is provided with a fixing means for the observation part of the observation object, and the objective is fixed with this fixing means. Observations are made by attaching it to the observation site.

[0005] For such an observation device fixed to an observation object, a main unit equipped with a recording means for recording image information captured by an object can be attached to the observation object, or a wireless communication means can be used. By forming the main device with an intermediate device that can be attached to the observation object and a reproducing device that is equipped with a display that reproduces and displays image information through wireless communication from the intermediate device, it is possible to Observation of a certain observation object, remote observation, etc. can be easily performed.

[0006] In addition, as an observation device fixed to an observation object for long-time observation of the same observation region of an observation object that is not in a moving state, a display is provided in the main device, and an objective tool is attached to the display. Captured image information can be reproduced.

The optical system unit 11 is formed by arranging one or more optical lenses 16 inside a light-shielding tube 15, and can select only light of a specific wavelength or A filter 17 for selecting or blocking only polarized light can be provided in the optical path.

The illumination system unit 13 is formed by arranging a plurality of light source lamps 18, 18, . This light source lamp 18, 18,
. . . may be provided in combination with lights with different emission wavelengths so that light with different wavelengths can be selectively irradiated as necessary. Further, this illumination system unit 13 may also be provided with a filter for polarizing the light from the light source lamp 18. Solid-state image sensor 12
is provided at the rear end of the light-shielding tube 15 so that the image formed by the optical system unit 11 can be taken.

The main device 3 includes a processing circuit 20 for processing image information from the solid-state image sensor 12, a recording means 21 for recording the image information processed by the processing circuit 20, and a light source lamp 18 and a processing circuit. It has a built-in power supply means 22 for supplying power to the circuit 20 and the like, and can be attached to an observation object using, for example, a belt.

This main device 3 stores image information in a recording means 21.
Although the structure is such that the information is recorded on the computer and later reproduced and observed using an appropriate reproduction device, this is not necessarily the case. That is, instead of such a main device 3, an intermediate device which can be attached to an observation object like the main device 3 but is equipped with a wireless communication means instead of the recording means 21 of the main device 3, It is also possible to use a main device consisting of a reproducing device equipped with a display that reproduces and displays image information through wireless communication from the device.

That is, the observation device main body 34 is equipped with a display 36, on which the image taken by the solid-state image sensor 12 in the objective 32 can be reproduced and observed in real time.

The illumination system unit 35 is formed of a light source 37 and a condensing guide 38 for efficiently irradiating light from the light source 37 onto the observation target site. The light source 37 guides light from a light source lamp (not shown) provided in the observation device main body 34 through an optical fiber bundle passing through the cable 33.
The irradiation tips of each of the optical fibers 40f, 40f... of this optical fiber bundle are planted in an annular holding member 41, and the optical fibers 40f, 40 arranged in this manner
The light emitted from the irradiation tip of f... is made to enter from an entrance end face 41 at the base end of a condensing guide 38, which will be described later.

The condensing guide 38 is made of a transparent material such as acrylic resin, and is formed into a cylindrical shape with a hollow hemispherical or hollow hemispherical front part, and a rear base. The end is an entrance end face 41, and a through hole 42 is bored in the center of the front part. And the entrance end surface 4
Light from the light source 37 entering from the light source 37 is guided through the solid interior to the through hole 42 by total reflection, and illuminates the observation target part of the observation object M from the inner surface in a substantially horizontal state, and at the same time, the light enters the entrance end surface 41. The light that leaks into the inside of the condensing guide 38 illuminates the observation target region from above as incident light.
