Description

[Detailed description of the invention] The present invention relates to a novel imaging device.
The objective lens barrel can be slid to easily focus, and the light rays emitted from the end of the optical fiber protruding into the tip of the close-up barrel provide uniform illumination without unevenness, resulting in clear images. This is something that can be obtained.

Because the close-up barrels of conventional imaging devices do not have a slidable objective lens inside,
If an image is taken with the open end of the close-up barrel in contact with a surface that has uneven parts, there is a drawback that the tip of the recessed or convex parts will be unclear on the screen, and the area to be imaged may not be illuminated by an external illumination device. Therefore, if the tip of the close-up cylinder is brought close to or in contact with the object to be imaged, the object to be imaged cannot be illuminated, and the screen may become unclear or an image may not be obtained. However, as a result of various experimental studies, the present inventor has developed the present invention without such drawbacks.

Below, a specific example of the present invention will be explained with reference to FIGS. 1, 2, and 3. A pot-like shape is placed inside a suitable part near the tip of a close-up barrel 2 that is detachably attached to a known image pickup device 1. A sliding body 3 is slidably inserted, an objective lens barrel 5 having an objective lens is fixed to the bottom 4 of the sliding barrel 3, and a protrusion 6 protruding from the outer periphery of the sliding barrel 3 is used for close-up photography. The sliding tube 3, that is, the objective lens tube 5, is moved forward and backward in the optical axis direction by protruding from the transparent groove 7 formed in the cylinder body 2 in the optical axis direction and pushing or pulling the protrusion 6 in the optical axis direction. This is for focusing. Optical fiber 8 made of a bundle of 1 to 100 colorless transparent glass wires or acrylic resin wires with a diameter of about 0.01 to 10.00 mm, preferably about 0.5 to 1.0 mm.
The tip 9 of the optical fiber 8 penetrates the tip 2' of the close-up cylinder 2 and protrudes into the interior, and the other end of the optical fiber 8 is introduced into the light source chamber 10 on the imaging device 1.
A light source 12 is provided on the other end surface 11.
In the figure, 13 is a condenser lens inserted between the other end surface 11 and the light source 12, 14 is an imaging tube, 15 is an imaging surface, 1
6 is the receiver, 17 is the front window of the receiver 16, 18
is a connection terminal for connecting another receiver.
The tip 9 of the optical fiber 8 is attached to the close-up barrel 2 so that the center line 19 of the tip 9 intersects the center 21 of the lower end opening 20 of the close-up barrel 2, and the end surface of the tip 9 of the optical fiber 8 is By making 22 a spherical protrusion, the entire surface of the imaged portion that is close to or in contact with the lower end opening 20 can be uniformly illuminated, and a clear image can be obtained.

In the present invention, for example, the skin before cosmetic treatment such as pine surgery is imaged, the image is confirmed by the beauty treatment person or the beautician using the receiver 16 of the imager 1 or another receiver, and if necessary, the skin is recorded. Then, after the beauty treatment, the same area is imaged, and as described above, the person receiving the beauty treatment or the beautician confirms the image and, if necessary, records the image, so that the beauty effect can be confirmed.

In the present invention constructed as described above, the close-up barrel 2 detachably attached to the image pickup device 1 can be removed and replaced with another close-up barrel or a standard or telephoto barrel, and can also be used for close-up photography. By moving the objective lens barrel 5 attached to the objective lens barrel 2 back and forth, if the imaged area has unevenness, a clear image can be obtained from either the concave portion or the convex portion. Further, the light beam emitted from the end surface 21 of the tip 9 of the optical fiber 8 protruding into the tip 2' of the close-up barrel 2 illuminates the imaged area without creating a shadow, thereby obtaining a clear image. It is something that can be done.

Another specific example shown in FIG. 4 is one in which a cylinder 23 is fixed to the tip of the close-up cylinder 2 by appropriate means, and the tip 9 of the optical fiber 8 is fixed to the cylinder 23. The same reference numerals as in the specific example indicate the same parts,
The effect is the same as that of the above-mentioned specific example.
