Description

41 9593 V. Description of the invention (1) [Detailed description of the invention] [Technical field to which the invention belongs] The present invention relates to an optical magnifying device 'more specifically, it relates to the optics used for the work of stereoscopically observing objects with two eyes. Expander. [Background Art] An optical magnifying device for work is usually constructed by combining a number of convex lenses with a size that can be viewed with both eyes. For example, the use of eyepieces to inspect the surface-inserted state of components of electronic circuit board components, the inspection and processing operations of small mechanical processing components, and other optical magnification devices used for operations have a structure that can be observed with two eyes. The structure of the observed object can be observed with a three-dimensional effect. The above-mentioned optical magnification device is a way of observing a virtual image of an object by an optical system formed by a convex lens, so 'if you want to increase the magnification ratio, it is necessary to shorten the focal length of the convex lens and shorten the distance from the objective lens to the observed object, in other words 'Short action distance. In addition, the optical magnification device observes the relationship between the object under observation with two eyes. The lens diameter becomes more than 100 mra. Compared with a magnification lens with the same degree of magnification, the lens configuration of the magnification lens 1 is similar. As the number tends to increase, the operating distance becomes shorter. As mentioned above, the conventional optical magnification device used for work is that if the enlargement ratio becomes larger, the distance between the object to be observed and the objective lens is close, which makes the operating distance extremely short, and it is impossible to reach into the object between the object and the objective lens.疋 It hurts the workability, and it becomes difficult to even illuminate the observed object. Clearly observing the object makes the operation itself difficult.

In addition, there is also an optical enlargement device such as the one described above, which is called a binocular solid microscope for the purpose of observing an object. The Yanhai binocular solid microscope is made from a low-magnification objective lens with a working distance of 1 ′. The high-magnification eyepiece makes it a virtual image to observe. Although the binocular solid microscope can increase the moving distance, it is necessary to observe the object in a three-dimensional manner, and the relationship between the eyepiece and the eyepiece must be close to the eyepiece. Since the position of the 'head is fixed, the optical amplifying device used for the operation described above cannot observe the object in a free posture, and is not suitable for long-term observation operations. [Disclosure of the invention] '' A first object of the present invention is to provide an optical magnifying device which can increase the distance between the eyepiece and the two eyes, and can observe the object with both eyes standing. Increase the enlargement rate, but it can make the action distance larger, and the operator can perform the work in a more comfortable position. More specifically, work with both hands while looking at the observed object with both eyes ^. A second object of the present invention is to provide a compact optical expansion device. To achieve this objective, the present invention effectively arranges an objective lens, an auxiliary objective lens (convex lens), a translucent reflector, a reflecting member, an eyepiece, and the like. The optical amplifying device according to the first invention is provided with a docking objective lens disposed on one of the left and right sides of the object to be observed, and an auxiliary objective lens (convex lens) disposed on the entrance side or the exit side of the pair of objective lenses to reflect the respective contacts.

In addition, in these inventions, a field-of-view lens for appropriately setting the distance between the eyepiece and the observation position may be arranged at or near the focusing position of the objective lens. The second invention is the first or second invention. Between the aforementioned semi-transparent mirror and the aforementioned second reflecting member, there is a configuration: a reflecting member for receiving outgoing light beams passing through the left and right of the semi-transparent mirror, and a first for receiving the reflected beam reflected by the first-middle reflecting member.

And 'the inverted image formed by each emitted light beam is trimmed into an upright image with two series of upright reflection optical systems respectively to form a substantially ^ orthogonal imaging surface, and then an eyepiece is used to view the object of the object viewed from the left side ^ The same light beam is guided to the left eye of the observer, and the light beam of the object viewed from the right side is guided to the right eye of the observer, and binocular vision can be used to stereoscopically observe the object. Inspection Therefore, although the enlargement rate is increased, the movement distance will not be reduced. In addition, as in the past, the magnification lens is used to observe with the eyes away from the eyepiece, and work in a comfortable posture.

Description of the invention (14) Similarly, the first reflecting member 7R for the right eye is reflected by the reflected light beam 6R reflected by the translucent mirror 5 and passed through the objective lens 2 and used by the left eye. The first reflecting member 7L reflects the vicinity of the reflection point 12L of the outgoing light beam for the left eye of the translucent mirror 5, and becomes the outgoing light beam 8R for the right eye, passes through the second auxiliary objective lens (convex lens) 4b, and enters the second reflection.

Description of the invention (15) Also, in this example of the form, the light beams 10L, 10R passing through the eyepiece 11 are emitted. The pupil position is provided with a guide mask 21 having a horizontally long opening 21 a so that it can be easily observed. The opening 21a is formed by the arcs of the left and right ends of the opening 21a being larger than the arcs of the exit pupils 13L, 13R of the left and right sides so as to easily catch the light beam with both eyes. The left and right exit pupils 13L and 13R of the optical enlargement device manufactured according to this embodiment are more than 20mm in diameter. Therefore, a skilled observer can immediately place his eyes on the exit pupil, but for beginners, there are It is difficult to capture the exit pupils that exist in the air. Also, some observers have difficulty watching the exit pupils 13L, 13R once captured for a long time. Therefore, the guiding mask 21 for observation is arranged near the exit pupils 13L, 13R so that the exit pupils 13L, 13R existing in the air can be easily found, and the observer's eyes can be surely guided. In addition, the effect of preventing external light, especially the lighting of the ceiling from reflecting into the eyepiece 11, can also be clearly observed. Also, the opening 21a of the shielding 21 for guidance is shown in the figure and is provided with a horizontal length. Shaped holes so that the exit pupil 3 L, i 3 r can be arranged on the left and right light shielding plates. It is also possible to achieve the goal by opening only the part that exits the pupil. However, it is more suitable for observers to avoid fatigue in the horizontally long shape. Furthermore, “the position between the optical paths of the outgoing light beams 8L, 8R passing through the semi-transparent mirror 5 and left and right is located between the aforementioned semi-transparent mirror 5 and the second reflecting member 9”, and there is illumination for disposing the object to be observed 丨The straight tube type fluorescent lamp 22.

4 7 9593 5. Description of the invention (16) In the case where the fluorescent lamp 22 does not shield the emitted light beams 8L, 8R, it is' located near the peripheral portion of the first auxiliary objective lens (convex lens) 4a, and is enlarged in contrast to the observer. One of the directions of the mirror, the illumination direction is directed only to the observed object 1 to avoid obstructing the observation. When the light source for illumination is arranged on one side of the observer, the lighting system protrudes and cannot directly look at the object to be observed 1, which impairs the workability relationship. Therefore, it should be arranged on the side opposite to the direction in which the observer looks at the magnifying glass. . In addition, the use of fluorescent lamps as lighting fixtures requires less heat from the light source and eliminates the need to use a fan to force exhaust. Therefore, the danger of damaging the observed object can be avoided. Also, unlike a highly directional light source such as a toothed lamp, the diffused soft light of a fluorescent lamp is easy to observe when illuminated from one side. In addition, this embodiment is configured to receive the light beam reflected at the middle position 12c of the light beam reflection point 12L, 12R passing through the center of the first auxiliary objective lens (convex lens) 4a through the left and right of the semi-transparent mirror 5 to reflect the object 1 23 and the camera reflecting member 24 for reflection and the camera reflecting beam 25 reflected by the camera reflecting member 24 are imaged on the imaging lens 27 of a CCD (Charge Coupled Element) camera 26. The present optical magnification device aims to observe the observed object 1 as an enlarged stereo image by visual observation. However, a method for simultaneously observing by a plurality of persons is a method for observing with a monitor television set of a CCD camera. At the same time, the CC D camera image can also be enlarged to be larger than the image seen with the naked eye, so as to magnify and observe it. As described in this embodiment, * the optical axis of the CCD camera is passed through the center of the first auxiliary objective lens (convex lens) 4a, and passed around the translucent mirror 5

Explanation of the invention (17) The relationship between the reflection point of the emitted light beam 12L and the intermediate position 12C of 12R can capture the image of the monitor without distortion. Therefore, in this embodiment, a CCD camera 26 can take an observation image with a correct shape, and observe with the eyes to obtain a stereo image, which is very desirable. In addition, the reflecting member 24 for photography can be a pentagonal prism that reflects twice the inversion conditions of the CCD camera in addition to a normal reflecting mirror. The reflecting member 24 and the imaging lens 27 for the camera are naturally disposed at Positions that do not interfere with beams 81 ^, 81 ?, 101, 101 ?. In addition, since the camera reflection member 24 to the CCD camera 26 are constituted as a unit, and the structure of the unit can be easily removed, a unit with a different magnification ratio, a variable focal length lens, and the like can be selected. Also, in the form examples shown in Figs. 1 to 3, as in the fourth form example, a field of view frame, a shielding for guidance, a light source for illumination, and a CCD camera can be provided. < f The interval β of the first reflection members 7L, 7R of one pair in the embodiment is again an angle slightly different from the angle at which an object can be naturally observed with both eyes. Also, "when the working efficiency is desired", the focal lengths of the objective lenses 2, 2L, 2R and the auxiliary objective lenses (convex lenses) 4, 4a, and 4b are set so that the operating distance becomes 1 or more when the magnification ratio is about three times. The light beams emitted from the objective lenses 2, 2L, and 2K are focused at the primary imaging position by converging the beams and by using the rear upright mirror optical system. The effect of the objective lens 2 of the 2 ′ 3, 4 aspect is the same as that of the objective element 2L, 2R of the first aspect. In addition, the first form example uses the relationship of the pairing rate L '2R, which is higher than that of the second, third, and fourth form examples. On the other hand, the second, third, and fourth form examples use Closed by an objective lens

According to the second form example shown in FIG. 3', the relationship between the optical axis of the semi-transparent mirror 5 to the second reflecting member 9 may be bent, and Reducing the depth of the optical enlargement device can reduce the size of the entire optical expansion device. The slave of the bent optical axis is arranged between the translucent mirror 5 and the second reflecting member 9 of the first embodiment. The same effect can also be obtained. In the optical magnification device of each embodiment, the comprehensive magnification is the product of the magnification of the imaging surface and the magnification of the eyepiece behind the imaging surface. Therefore, 'the magnification on the imaging surface is set to be smaller than the comprehensive Enlargement rate. In order to obtain the same observation environment as the conventional enlargement lens, it is necessary to set the exit pupils 13L and 13R of the optical system at a distance of more than 100mm from the rear of the eyepiece. The sizes of 13L and 13R are: It should be set as large as possible, specifically, s, with a size of 20mm or more. Also, although the relationship between the position and size of the exit pupil from the lens is not shown in Figure j and Figure 2, the field of view lens 6 can also be connected to the objective lens 2L. 2R or near the imaging position of the objective lens 2. Of course, the magnification change of the enlargement device of the two forms can be implemented by changing a pair of objective lenses 2L, 2R or an objective lens 2 to a different magnification. However, the auxiliary objective lens ( It is also possible to change to a different magnification. It is also possible to change the eyepiece to a different magnification. It is also possible to use the auxiliary lens (convex lens) superimposed on the% change of magnification. Align the position of the exit pupil with The eye tone of the observer's eyes
