The present invention relates to a handy camera having an illumination device using an optical fiber, and more particularly, to protect the optical fiber from external shock applied to the camera by using an internal housing and a flash cap mounted inside the handy camera, The present invention relates to a handheld camera that prevents light emitted from an optical fiber from directly entering a lens of a camera by using an internal housing even when the optical fiber is separated from the home position.

In general, cameras can be equipped with lenses of various magnifications, thereby expanding and observing microstructures, thereby inspecting and treating hair, skin, teeth, iris, etc. as well as industries such as semiconductor or LCD inspection. It is widely used in the medical field of the medical field, and in particular, a handy type camera equipped with a lighting device for illuminating a subject to obtain a clear image has been developed and widely used.

1 is an exploded perspective view of a medical or industrial camera according to the prior art, a handy camera having an illumination device using an optical fiber. A protruding support 2 is formed in front of the housing 1 of the camera so that the lens 3 is coupled, and a through hole 4 is formed in the front of the support 2 so that one end of the optical fiber 5 is formed. The other end of the optical fiber 5 is connected to the light source through the coupling hole 7 formed in the lower end of the housing cover 6 through the inside of the housing 1 of the camera. At this time, between the housing 1 and the housing cover 6, an image recognition device 8 for photographing a subject enlarged or reduced through the lens 3 is located. In addition, the cap 2 can be coupled to the support 2 so that the camera can be photographed in close contact with the subject, and the light emitted from the optical fiber 5 is propagated along the surface of the cap 9 to capture the image. It helps to reach the part intensively.

At this time, in order for the light emitted from the optical fiber 5 to efficiently direct the subject, the cut surface of the optical fiber 5 arranged around the lens 3 should be directed in the same direction as the lens 3 of the camera. In order to prevent the image from being blurred, the light emitted from the optical fiber 5 should be prevented from directly entering the image recognition device 8. However, in the conventional handy camera, since the optical fiber 5 is arranged on the support 2 formed to protrude from the housing 1, the optical fiber 5 is broken due to external impact or the optical fiber 5 is separated from the fixed position and thus the optical fiber. There is a structural problem that the cut surface of (5) is not directed toward the subject and the efficiency is lowered when the subject is illuminated. In addition, since the optical fiber 5 is connected to the light source while passing directly inside the housing 1, the optical fiber 5 arranged on the support 2 may retreat into the housing 1 by an external impact. In this case, there is a problem in that light emitted from the optical fiber 5 directly flows into the image recognition device 8 and the image is blurred and photographing becomes impossible.

The present invention is to install a separate inner housing in the housing of the handheld camera to solve the above problems, and the external shock is directly applied to the optical fiber by arranging the optical fiber is coupled to the flash cap coupled to the inner housing. It prevents the breakage of the optical fiber or detachment from the fixed position, and even if the optical fiber is separated from the flash cap, the inner housing blocks the light emitted from the optical fiber and the light emitted from the optical fiber flows directly into the image recognition device. SUMMARY OF THE INVENTION An object of the present invention is to provide a handy camera that prevents a clear image to be obtained.

Handheld medical camera equipped with a lighting device using the optical fiber of the present invention for achieving the above object is a housing having a gripping portion of the gun shape to be gripped by the operator, the housing coupled to the rear of the housing A lens unit, which is accommodated inside the housing, through a housing through-hole in front of the housing, aims the subject and enlarges or reduces the subject, and photographs a subject enlarged or reduced by the lens unit and outputs the image signal. A handy camera comprising an image recognition device, a focus control unit for focusing the image recognition device by moving the image recognition device forward and backward, and an optical fiber for illuminating a subject during shooting, wherein the camera is in close contact with the housing through-hole between the housing and the housing cover. An inner housing accommodating the lens unit, the image recognition element, and the focus control unit; Position, and the front cap has a flash comprising a plurality of cutting of the inner housing is mounted, characterized in that the flash cap has a plurality of optical fibers are inserted so as to be exposed to the outside by way of a coupling the section.

In this case, the inner housing is composed of a lens unit coupling portion into which the lens unit is inserted and extends rearward from the lens unit coupling portion, and an inner housing body accommodating the image recognition element and the focus control unit therein. The optical fiber is fitted to the coupling peripheral surface and the inner peripheral surface of the flash cap may be characterized in that the end of the optical fiber is exposed to the cutout of the flash cap.

In addition, a plurality of receiving grooves in which the optical fiber bundle is accommodated may be formed on the circumferential surface of the lens unit coupling portion.

In addition, the handy medical camera having a lighting device using the optical fiber of the present invention may be characterized in that a passage through which the optical fiber passes through a predetermined portion between the inner peripheral surface of the housing and the outer peripheral surface of the inner housing.

Hereinafter, described in detail by the accompanying drawings as follows.
