Description

  The present invention relates to a simple endoscope attached to a camera lens portion of a mobile phone.

  As endoscopes, medical endoscopes and industrial endoscopes are known, and for general consumers, monitors, optical fibers, and cameras are provided, and the interior of car engine rooms and household piping are observed. Or the fiberscope for imaging | photography is marketed. In recent years, devices that have a USB terminal and can be connected to a notebook computer or the like to observe a desired object on a large screen are also commercially available.

  Patent Document 1 discloses an industrial endoscope including a camera head and an irradiation mechanism that are miniaturized in order to photograph a narrow pipe.

JP 2010-55023 A

  When you want to observe the part of your body that you are interested in, such as the back side of your teeth, nostril, ear canal, buttocks, etc., it is common to use a hand mirror. It is difficult to do. Also, obtaining a medical endoscope for this purpose is not practical from the viewpoint of cost.

  For this reason, it is conceivable to purchase a commercially available endoscope represented by the industrial endoscope described in Patent Document 1, but it is a very expensive system for professional use.

  In recent years, simple fiberscopes connected to personal computers and equipped with dedicated monitors have been sold to general consumers for the purpose of observing and taking pictures of car engine rooms and household piping. However, this is also relatively expensive and lacks ease of carrying.

  In view of the above problems, the present invention can be connected to the camera lens part of a mobile phone that everyone has on a daily basis, and can display and shoot a part of his / her body on the display of the mobile phone. An object of the present invention is to provide an inexpensive simple endoscope.

  According to a first aspect of the present invention, there is provided a simplified endoscope having an eyepiece lens portion at one end of an optical fiber having a certain length and an objective lens portion at the other end, and the eyepiece portion is attached to a mobile phone by a mounting tool. It is mounted on a camera lens portion, and an observation target region is displayed on a display of the mobile phone using an image photographing system of the mobile phone.

  The simplified endoscope according to the invention described in claim 2 is configured such that an LED light source is installed in the simplified endoscope according to claim 1 and the image of the dark part can be clearly displayed on the display. It is characterized by.

  A simplified endoscope according to a third aspect of the present invention has a suction cup as the wearing tool, and the eyepiece lens section and the camera lens section of the mobile phone are connected by the suction cup.

  The simple endoscope according to the invention of claim 4 has a spring-clamping tool as the wearing tool, and the connection between the eyepiece lens unit and the camera lens unit of the mobile phone is performed by the spring-clamping tool. It is characterized by.

  The simple endoscope according to the invention of claim 5 has a steel spring as the mounting tool, and the connection between the eyepiece lens unit and the camera lens unit of the mobile phone is performed by the pinching tool with spring. Features.

  By providing a simple endoscope according to the present invention, it becomes possible to construct a low-cost system that is a combination of a cellular phone and a fiberscope that everyone has on a daily basis. You can zoom in for easy observation. In addition, there is an effect of reusing an old type mobile phone that has been discontinued.

It is a side view of the simple endoscope which uses a suction cup for a mounting tool. It is a side view of the simple endoscope which uses the pinching tool with a spring for a mounting tool. It is a side view of the simple endoscope which uses steel springs for a mounting tool.

  Embodiments of the present invention will be described below with reference to the drawings.

The basic configuration of the simple endoscope 1 according to the present invention is that an eyepiece unit 3 having an eyepiece 31 is installed at one end of an optical fiber 2 having a length of about 1000 mm, and an objective lens 41 and a support pipe 42 are installed at the other end. Is provided. Further, the eyepiece lens unit 3 is configured to allow the simple endoscope 1 to be attached to the camera lens unit 51 of the mobile phone 5 while maintaining a proper distance between the eyepiece lens 31 and the camera lens unit 51 of the mobile phone 5. A mounting tool 33 and a focus adjustment dial 32 for the eyepiece 31 are provided.

  The objective lens 41 of the objective lens unit 4 is installed at the tip of a stainless steel support pipe 42 having a length of about 10 mm while maintaining an elevation angle of 30 to 45 degrees.

  The mounting tool 33 can be a resin suction cup 33A as shown in FIG. 1, a holding tool 33B with a spring as shown in FIG. 2, or a steel spring 33C as shown in FIG.

Moreover, in order to irradiate light to the observation target site in the dark part and obtain a clearer image, the simplified endoscope 1 includes a battery holder 35 for storing the LED light source 34 and a power source for this purpose. It is also possible to comprise. The power source used is assumed to be a AAA type battery in FIGS. 1 to 3, but a button type battery (not shown) can also be used.

As the usage of the simplified endoscope 1 , first, the simplified endoscope is used by using the suction cup 33A (FIG. 1), the spring-loaded clamp 33B (FIG. 2) or the steel spring 33C of the eyepiece unit 3. The eyepiece 3 of the mirror 1 is attached to the camera lens 51 of the mobile phone 5 to turn on the camera function of the mobile phone 5. Next, when the objective lens unit 4 of the simplified endoscope 1 is directed to a desired observation site, for example, the outer ear hole, and the LED light source 34 is present, the switch of the light source is turned on. Finally, the focus adjustment dial 32 of the eyepiece lens unit 3 is turned to adjust the focus while watching the image displayed on the display of the mobile phone.

  Furthermore, the user can operate the mobile phone 5 as necessary, take a picture or record a video, drop the photo or video into the storage device of the mobile phone 5, and review it later on a large screen of a personal computer or the like. It becomes.
