JP7217442B2 - Camera adapter for barrel - Google Patents

Description

The present invention relates to a camera adapter for lens barrels of microscopes, field scopes, telescopes, etc. (hereinafter referred to as optical system measuring devices), and is used for photographing devices attached to these optical system measuring devices.

The lens barrel camera adapter for the optical observation device (hereinafter referred to as the lens barrel camera adapter) is used to fix the camera or video camera to the optical observation device for the purpose of photographing the observed image with the camera or video camera. The captured images can be displayed on personal computers, mobile terminals, tablet terminals, monitors, screens, etc., and can be saved in various storage media.
Since the diameters of the eyepieces and lens barrels and the size and shape of the camera lens differ depending on the type of optical system observation device, camera, and video camera, the shape and structure of the adapter are designed to match the size and shape of each type. There are many different types. There is also a shape that can be inserted into a photographic cylinder, or that can be inserted into a lens barrel after removing the eyepiece.

Conventional optical system observation device lens barrel camera adapters have the problem of dust getting inside the lens barrel because the eyepiece is removed and the camera adapter is inserted to take an observation image.

In addition, there are camera adapters that can be installed without removing the eyepiece as mentioned in prior art documents, but there are a wide variety of fixing functions and fixtures that match the diameter of the lens barrel of the optical system observation device. For the purpose of fixing the observation image and adjusting the position of the camera lens, there is a problem that it is necessary to adjust the photographing device such as the camera to an appropriate photographing position using a screw or the like.

In addition, the camera adapter for the lens barrel of the conventional optical system observation device uses an appropriate adapter and parts according to the size of the eyepiece and lens barrel, and arranges the camera and other imaging devices at appropriate shooting positions. I had to let

Therefore, in order to solve the above-mentioned problems, the present invention is designed so that a camera or other photographing device can be placed in an appropriate photographing position while the eyepiece is attached to the lens barrel, regardless of the size of the eyepiece or lens barrel. To provide a camera adapter capable of securely fixing a photographing device such as a camera at an appropriate photographing position on the axis of a lens barrel without using an adapter or parts corresponding to the size of the barrel.

A microscope for photographing an observation image of the optical system observation device according to the embodiment of the present invention, a camera adapter for fixing the optical system observation device and the camera are rotatable in order to sandwich the lens barrel of the optical device of the optical system observation device. A holding part composed of a pair of members sharing a common shaft, a spring that generates a force for holding the lens barrel in the holding part, and a photographing device such as a camera positioned at the center of the rotation axis. It has a shooting point where the shooting unit is arranged.

At the photographing point where the photographing unit of the photographing device located in the center of the rotation axis of the present invention is arranged, the lens of the photographing device can be arranged. An adapter or the like dedicated to the device may be installed and connected.

In order to sandwich the lens barrel of the optical system observation device of the present invention, the contact portions of the pair of members sharing the rotation axis with the lens barrel can maintain a sufficient holding force even for lens barrels of different sizes. Thus, the gripping portions of the pair of members are curved so that the contact portion with the lens barrel has an appropriate size according to the degree of opening and closing of the pair of members.

In addition, since the size and shape of the lens barrel are mostly manufactured according to the standard, instead of using the curved surface described above to continuously change the size and shape of the holding part, the lens barrel Assuming the standard of , it is also possible to change the shape of the holding part in stages.

Due to the individual characteristics of the microscope, lens barrel, eyepiece, etc., it is easy to assume that the eyepoint is off the axis of the lens barrel to which the eyepiece is attached. It also has a mechanism for fine-tuning the shooting point.

As described above, according to the present invention, regardless of the size of the lens barrel of the optical system observation device, the photographing point for arranging the photographing unit of the photographing device such as a camera such as a microscope is arranged on the axis of the lens barrel. , the observation image of the optical system observation device can be easily and conveniently photographed without changing the adapter according to the size of the lens barrel.

It is a figure which shows the structure of the Example of this invention. (Example 1) FIG. 4 is a diagram showing the arrangement of a configuration in which the embodiment of the present invention is attached to the lens barrel of the optical system observation device; It is a perspective view from the upper part which shows arrangement|positioning of the structure which attached imaging devices, such as a camera, in the Example of this invention. FIG. 2 is a perspective view from below showing the photographing positions of a photographing device such as a camera mounted in an arrangement in which a photographing device such as a camera is mounted in an embodiment of the present invention; It is the figure which attached photographing devices, such as a camera, to the Example of this invention, and attached the position adjustment dial. (Example 2)

Several exemplary embodiments of the camera adapter of the present invention are described.

A representative embodiment of the present invention will be described with reference to the drawings. 1 is a side view of a camera adapter according to the present invention; FIG.

In FIG. 1, 2 is the pinch portion of the camera adapter 1, and the lens barrel is sandwiched between a pair of pinches facing each other and the lens barrel holding portion 4 of the pinch, and the force for fixing the camera adapter 1 to the microscope. 3 springs for generating , and 5 springs in the 4 lens barrel gripping portions so as not to damage the lens barrel when the camera adapter 1 grips the lens barrel with the 4 lens barrel gripping portions. The lens barrel holding part cushion is provided. The material of the camera adapter 1 and the lens barrel holding part cushion 4, which constitute this embodiment, is not limited, but in consideration of the load and safety on the optical observation device, a functional resin material is used. Alternatively, a light metal-based material is preferable, or a carbon-based material or the like can be used.

FIG. 2 shows a side view of a state in which the lens barrel portion of the optical system observation device 9 is sandwiched between a pair of pinch portions 2 of the camera adapter 1. As shown in FIG. The central portion of the camera adapter 1 is uniquely arranged on the central axis of the lens barrel of the optical system observation device 9 regardless of the size of the diameter of the lens barrel portion of the optical system observation device 9.
