Description

  The present invention is an electronic camera including a digital camera and a photographing camera for a mobile phone, in addition to a normal built-in lens, in order to attach a new additional lens so that ultra high magnification photographing is possible.

  In order to mount a conventional lens for high-magnification extended shooting on the lens head portion, a jig for attaching and detaching with a magnet or the like has been considered in order to simplify the mounting. In addition, it is only a technique of a method of slightly increasing the magnification from the normal magnification, and a method of fitting a lens system using a large spherical lens into a whole optical camera in a cassette type has been adopted.

The problem the device is trying to solve

  At first glance, the attachment / detachment method of the lens component using a magnet or the like can be considered as an easy method. However, in actual installation, the magnetic field of the magnet affects the electronic components, and the image may be distorted. In addition, a conventional lens having a large aperture must be applied to a camera having a different shape and size, and inevitably has a large shape and it is difficult to align the center of the lens.

Means to solve the problem

  In the present invention, in order to attach an ultra-high magnification lens to a small electronic camera, first, an ultra-compact and light weight was achieved by an optical system including an aspherical surface of the attachment lens system. Taking advantage of advanced lens design technology, ultra high-magnification photography has become possible by attaching at most one or two lenses.

Effect of device

  The lens system thus reduced in size and weight is extremely easy to attach to and detach from the electronic camera body, and can be combined with the zoom shooting mechanism of the electronic camera body without any troublesome lens mounting operation and adjustment. High-magnification photography that can be changed is possible.

  When attaching to an electronic camera, a double-sided adhesive tape is attached to the main body camera side of the mounting lens, allowing the combined optical system to achieve an ultra-high magnification. When this lens is removed, the original function capable of photographing up to infinity can be restored. Therefore, this tape must have a suitable strength so that the mounting lens does not fall when applied and can be easily peeled off from the main body when removed. In addition, unlike the conventional case, it is possible to easily attach and detach the cassette body to the camera body by utilizing the characteristics of a small lens.

  Embodiments will be described with reference to the drawings. FIG. 1 shows a mechanism for ultra-high magnification photographing in the present invention. Reference numeral 1 denotes a single lens or a lens for ultra-high magnification including an aspheric surface composed of a plurality of lenses, 2 is a lens holder thereof, and 2a is a lens holder. Indicates the lens holder. In order to attach the lens holder to the electronic camera, the double-sided adhesive tape 3 cut out in a cylindrical shape is attached to the camera body. FIG. 2 shows an example in which the ultra-high magnification lens unit 4 having the above-described configuration is attached to the center of the lens portion of the mobile phone electronic camera 5 with the optical axis aligned. The figure shows an example of attachment to a camera for a mobile phone having a very small aperture. The outer diameter of the entire holder is about 10 mm at the maximum, and an excessively large one hinders other parts. Double-sided tape for attachment and detachment must have adhesive strength suitable for this outer diameter, and must be easily peeled off for removal.

  FIG. 3 is a view in which a mounting flange 6 is attached to a digital camera 7 with a zoom mechanism attached to a digital camera 7 of a type in which the lens of the camera body is extended forward according to the magnification in order to have a zoom. In this figure, the zoom unit is retracted to the front of the camera, but in general, the main body lens significantly moves back and forth for zooming. Accordingly, the flange diameter of 6 is designed to be suitable for a zoom mechanism of a digital camera. The optical system including the holder is basically the same as that shown in FIG. 1, but the interchangeable lens holder 6a adjusts the lens position by rotating the screw with respect to the mounting flange 6 as shown in FIG. Make it removable.

  FIG. 4 shows that the lens holder surface is not bonded using a double-sided tape as described above, and ultrahigh-magnification shooting is realized by fitting the cassette 8 integrated with 4 into the electronic camera 5 for mobile phones. The As a matter of course, the lens holder portion of the cassette has a mechanism similar to that shown in FIG. This production is considered suitable for a system in which the shape of the cassette is designed to match the shape of various electronic cameras and mass production is performed using a molding die.

    In FIG. 5, ultra high-magnification photography is possible by fitting the screw 9a on the side surface of the lens holder with the screw 9b of the electronic camera body. Since the outer diameter of the screw is completely different depending on the camera for various mobile phones, it is difficult to adapt to all types of cameras like a pasting mechanism. In this way, the lens holder attached to the camera body enables ultra-high magnification enlargement shooting together with the performance of the lens in the holder and the enlargement zoom function of the camera body. In the case of a commercially available digital camera, the maximum magnification reaches 800 times or more in terms of a 17-inch monitor, and cell observation becomes possible. Accordingly, it is possible to make a completely new and innovative observation without using a microscope in the field of living organisms and living organisms. In addition, if the resolution chart is used, a resolution of 4 microns or less can be confirmed, and the dot pitch of the C-MOS sensor can be recognized.

Claims (4)

  When a lens system including an aspherical surface is created and attached to the electronic camera for the purpose of taking an ultra-high magnification of the electronic camera, a double-sided adhesive tape is attached to the bottom surface of the lens holder on the camera side so that the camera can be attached and detached. A screw mechanism is provided on the flange and the lens holder for increasing the magnification, and the position of the lens is adjusted by rotating the screw to facilitate lens replacement.
For attachment to the camera body, a double-sided adhesive tape is attached to the bottom surface of the flange so that it can be attached to and detached from the camera.     A cassette integrated with the lens holder for ultra-high magnification is created according to the shape of the electronic camera, and the lens holder can be easily fitted into and attached to the electronic camera body.     Screws are provided on the side surfaces of the lens mechanism of the electronic camera, and the screws are fitted to each other by screw rotation provided on the outer periphery of the fitting lens holder.
