Description

A microscope with a digital photographing apparatus

The present invention relates to a microscope having a digital imaging means, and more particularly, to a microscope having a digital imaging means having a small external appearance by the built-in microscope body having a digital imaging means in the housing of the microscope.

A general microscope is an experimental apparatus used for research and learning purposes in the scientific field, and is a device that enlarges an object that cannot be directly observed by the human eye. When using such a microscope, it was difficult for the observer's eyes to be tired easily or the observer photographed the object and recorded it because the observer had to directly contact the lens of the microscope. In order to compensate for this, in the related art, a device such as a digital camera is installed in a conventional microscope so that the subject can be photographed or the image can be viewed through a screen.

The technique related to the microscope equipped with such a digital imaging means is disclosed in Korean Utility Model Registration Application No. 1999-0010158 as shown in FIG.

1 is a perspective view showing a state in which a digital imaging means is installed in a microscope according to the prior art.

As shown in FIG. 1, the microscope equipped with digital imaging means includes a pedestal 20 for supporting the body of the microscope, and the light source lamp 10 is embedded or attached to the pedestal 20. The light source lamp 10 adjusts the brightness of the observation object by providing light so that the observation object can be easily observed, and the optical axis scanned by the light source lamp 10 is installed perpendicular to the observation object. In addition, the microscope of the prior art is provided with a specimen pedestal 30 for supporting the specimen on which the observation object is placed, and an objective lens 40 for directly enlarging the image of the observation object. In the objective lens 40, a rotary objective lens provided with a plurality of lenses having different magnifications is used. In this rotary objective lens, each lens magnifies an optical axis scanned by the light source lamp 10 when the image to be observed is magnified. It is located on the straight line of.

In addition, a rotating plate 41 for fixing and rotating the rotary objective lens 40 is attached to the body 50 positioned at the upper portion of the microscope, and the eyes of the observer are directly contacted to the side extending from the body 50 upwardly. The eyepiece 60 is combined. Since the eyepiece 60 is not located in a straight line with the central axis of the objective lens 40, the image of the observation target magnified by the objective lens 40 is attached to the eyepiece 60 on the body 50 of the microscope. A mirror or prism (not shown) is built in so as to be transmitted.

Then, a barrel 51 is formed on the upper surface of the body 50 through which the central axis of the objective lens 40 passes, and the digital camera 70 is coupled to the barrel 51 by the adapter 71.

The conventional microscope thus constructed is operated by the following principle. First, the specimen is placed on the specimen holder 30 to operate the light source lamp (10). Then, the position of the specimen pedestal 30 is adjusted to adjust the focus of the objective lens 40 with respect to the observation object placed on the specimen. Then, the objective lens 40 magnifies the image of the observation object and sends the image to the eyepiece 60 through the prism, and the observer directly observes the image.

In addition, the observer rotates the rotating plate 41 to observe the magnification of the objective lens 40 with respect to the image to be observed while adjusting the lens from the low magnification lens to the high magnification lens.

In addition, when the observer wants to take an image of the observation object, the image of the observation object is sent from the objective lens 40 to the digital camera 70 and the image is captured.

However, the microscope of the prior art as described above is because the light source lamp 10, the specimen support 30, the objective lens 40 and the digital camera 70 is located on the optical axis provided by the light source lamp 10, The volume tends to increase and its height increases. For this reason, the center of gravity of a microscope becomes high, and there exists a problem that the expensive microscope falls and breaks often arises.

In addition, the microscope user has a problem in that it is inconvenient to carry the microscope because the microscope user needs to put it in a separate large case or hold it with both hands and walk carefully.

The present invention is provided to solve the problems of the prior art as described above, the microscope body is equipped with a digital imaging means in the housing of the microscope is built in the shape of the external shape and the digital is smaller than the shape of the prior art microscope It is an object of the present invention to provide a microscope equipped with an imaging means.

As shown in Figure 2 to 6b, the microscope 100 is equipped with a digital imaging means of the present invention is built in the microscope body 101 of the microscope housing 101. In particular, the main body 105 of the microscope includes a light source unit 110 for scanning light, a specimen base 130 on which the specimen is placed, an objective lens unit 140 for enlarging the object to be observed, and an enlarged image of the object to be observed. A digital imaging means for photographing is provided, and a reflection mirror for changing the optical axis of the light to be scanned is provided between the above components. For this reason, the microscope 100 having the digital imaging means of the present invention is smaller in size than the microscope of the prior art.

Below will be described in more detail for each component of the present invention as described above.

The power supply 103 is attached to the housing 101, and the light source lamp 111 of the microscope main body 105 is operated by operating this power switch 103. As an example, the light source lamp 111 is used as a filament bulb and scans light. In addition, light is radiated from the light source lamp 111, and the light is collected by one optical axis 171 to reach the first reflecting mirror 121. In addition, the position of the optical axis 171 may be finely adjusted little by little. For this purpose, the light source unit 110 including the light source lamp 111 is configured as follows (see FIG. 3).

The light source lamp 111 is inserted into the lamp socket 112 and inserted into the lamp protector 115. The lamp protector 115 has a circular hole formed on one surface thereof so that the light source lamp 111 can be inserted, and the inside thereof is hollow. In addition, another hole is formed in the other surface of the lamp protection tool 115 facing the hole into which the light source lamp 111 is inserted so that the light scanned from the light source lamp 111 travels forward. The condenser lens 118 attached to the other surface of the lamp protector 115 collects the scanned light onto one optical axis 171 (see FIGS. 6A and 6B).

In addition, a lamp mount 117 which is hollow is attached to one surface of the lamp protector 115, and a lamp adjuster 113 is inserted into and contacted with the inside of the lamp mount 117. In addition, the end of the ball plunger (116) slightly protrudes on the inner circumferential surface of the lamp mount 117, such a ball plunger 116 moves in accordance with the rotation of the lamp adjuster 113 in contact with the lamp socket Adjust the position of 112. That is, the observer finely adjusts the optical axis 171 of the light source lamp 111 by adjusting the position of the lamp socket 112 that interlocks with the ball plunger 116 by rotating the lamp adjuster 113. The ball plunger 116 also serves to prevent the lamp adjuster 113 exposed to the outside of the housing 101 from being separated from the main body 105.

In addition, the light source unit 110 is the condenser lens 118, the light source lamp 111, the lamp socket 112, and the lamp adjuster 113 are sequentially positioned in a straight line, the horizontal of the microscope to the ground on which the subject innovation is placed Coupled to the body 105. Therefore, the optical axis 171 of the light source unit 110 proceeds horizontally to the ground, so that the height of the light source 110 relative to the ground becomes lower than that of the conventional microscope.

The optical axis 171 is transferred to the condenser lens 122 in a direction in which the optical axis passes through the first reflection mirror 121 in a direction perpendicular to the ground. Above the condenser lens 122, the specimen support 130 is positioned on the optical axis at regular intervals. And, the specimen pedestal 130 is coupled to the focusing lever (lever) attached to the main body 105 of the microscope, this focusing lever is moved to the specimen by placing the specimen pedestal 130 in a rack and pinion manner observation object The objective lens unit 140 is adjusted to be positioned at the focal point. The first focus lever 131 moves the specimen bracket 130 in the X direction, the second focus lever 132 moves in the Y direction, and the third focus lever 133 moves in the Z direction. The focusing levers 131, 132, and 133 are exposed and installed in front of the housing 101 so that the viewer can operate the same. Then, the specimen on which the observation target is placed is placed on the specimen support 130 (see FIG. 3).

The objective lens unit 140 positioned on the line of the optical axis 172 changed by the first reflecting mirror 121 enlarges the image of the object to be transmitted to the second reflecting mirror 150. The objective lens unit 140 is coupled to the upper frame 106 of the main body 105 to be detachable. To this end, the objective lens unit 140 includes a lens unit for enlarging an image of an object to be observed, a fixing piece fixed to the lens unit and coupled to the upper frame 106, and the viewer directly pushes and pulls the objective lens unit 140. It is composed of a handle portion fixed to the fixing piece to be. In addition, in order for the fixing piece to be coupled to the upper frame 106, a groove is formed in the side of the fixing piece made of a rectangular parallelepiped, and an engaging groove corresponding to the fixing piece is formed in the upper frame, and protrusions are raised on the inner side thereof, The projection of the engaging groove is engaged (not shown). After the observer replaces the objective lens unit 140, the observer closes the sliding door 102 formed in the housing 101. The sliding door 102 is a means for protecting the objective lens unit 140 from external impact, and is coupled to be movable up and down along a pair of guide grooves formed in the front of the housing 101.

In addition, the image of the observation target transmitted to the second reflection mirror 150 is changed to the optical axis 172 at a right angle again and transmitted to the third reflection mirror 152. The optical axis 173 changed in the second reflecting mirror 150 changes horizontally on the ground and proceeds.

As shown in FIGS. 3 and 4, the rectangular second reflecting mirror 150 is tilted 45 degrees with respect to the traveling direction of the optical axis 172 to the first barrel 151 so that the optical axis 172 is changed again. Combined. The first barrel 151 has a rectangular hollow cross section and is coupled to the upper frame 106 at a predetermined distance from the objective lens unit 140. The image transmitted to the third reflecting mirror 152 after passing through the first barrel 151 is changed so that the traveling direction of the optical axis 173 is horizontal and perpendicular to the ground. To this end, the rectangular third reflecting mirror 152 is coupled to the optical axis 173 passing through the first barrel 151 by 45 degrees. The image of the observed object is transferred from the third reflecting mirror 152 to the charge coupled device (CCD) camera 160, which is a digital imaging means, in the traveling direction of the optical axis and photographed. In addition, a second barrel 153 is coupled to the upper frame 106 around the optical axis 174 changed by the third reflection mirror 152.

Since the image of the observation target transmitted from the objective lens unit 140 as described above is changed while the advancing direction of the optical axes 171, 173, 174 progresses horizontally to the ground, the subject innovation compared to the microscope of the prior art The height from the lens unit 140 to the digital imaging means is lowered. That is, the present invention, unlike the microscope of the prior art, is made into a stable and standardized rectangular shape by changing the optical axis, it is possible to manufacture in a small size.

As shown in FIGS. 3 to 5, the CCD camera 160 is connected to the upper frame 106 using the connecting line 161, and the lower portion of the main body 105. Coupled to the combined signal divider 163. The USB board 162 edits a signal of a screen captured by the CCD camera 160 and sends the signal to the USB terminal 164 of the signal splitter 163. The digital imaging means such as the CCD camera 160 and the USB board 162 is embedded in the main body 105 of the microscope, and the output terminal of the signal distributor 163 is exposed to the housing 101. The output terminal of the signal splitter 163 is provided with a USB terminal 164 for a computer, a TV terminal 165 for a TV, and an S terminal 166 for a high resolution monitor, respectively.

In addition, a power supply device 167 is provided below the housing 101 to supply power to the light source lamp 111 by the operation of the power switch 103. In addition, the power supply device 167 also supplies power required by the digital imaging means through a connection line.

FIG. 7A is a view illustrating a state in which an auto collimator is installed in the microscope body to adjust the optical axis shown in FIG. 4, and FIG. 7B is a cross-sectional view partially cut along the line A-A shown in FIG. 7A.

As shown in FIGS. 7A and 7B, the optical axis 174 whose direction of travel is changed in the third reflection mirror 152 is finely adjusted. For this purpose, the optical axis adjusting plate is attached to the first barrel 151. This optical axis adjustment plate is coupled to the side surface of the first barrel 151 by the first adjustment screw 154, the other surface 158 is bent from the one surface 157 to the upper frame 106 is extended. The second adjusting screw 155 is engaged. One surface 157 and the other surface 158 of the optical axis adjustment plate are formed with holes through which the first and second adjustment screws 154 and 155 pass, respectively. These holes are the first and second adjustment screws 154 and 155. Since it is larger than the diameter but smaller than its head, the first barrel is moved up and down or left and right so that the optical axis 174 is adjusted.

This optical axis 174 is adjusted by the following method. First, the auto collimator 300 is used to change the optical axis 174. The auto collimator 300 is a mechanism used to perform zero adjustment, and in this case, the auto collimator 300 is installed in the main body 105 in which the housing 101 of the microscope is separated. After removing the CCD camera 160 from the main body 105, the auto collimator 300 is attached to the second barrel 153, and the horizontal adjuster 305 is placed on the front of the main body 105 on the V block 304. Install it to adjust the level. Then, after the light is injected from the lamp 301, the light returned from the reflecting mirror is observed through the observation port 302. At the observation port 302, the light is biased from the zero position. In this case, the first barrel 151 is finely moved up and down or left and right by loosening the first and second adjusting screws 154 and 155, respectively. The zero angle is adjusted by changing the reflection angle of the third reflection mirror 152 coupled to 151. Then, the first barrel 151 is fixed by tightening the first and second adjustment screws 154 and 155 again.

Hereinafter, the operation relationship of the microscope equipped with digital imaging means will be described in detail.

First, the specimen placed on the upper surface of the specimen support 130 is placed. Then, the light source lamp 111 is operated by operating the power switch 103. In the activated light source lamp 111, light is scanned, and in the condenser lens 118, the light travels along the optical axis 171. The optical axis 171 reaches the condenser lens 122 by changing its traveling direction perpendicular to the ground in the first reflecting mirror 121. The transmitted light illuminates the observation object, and the image of the observation object is transmitted along the traveling direction of the changed optical axis 172.

In addition, the objective lens unit 140 magnifies an image of the object to be transmitted to the second reflecting mirror 150. In the second reflecting mirror 150, the optical axis 172 is changed to be perpendicular to the third reflecting mirror 152 horizontally to the ground, and in the third reflecting mirror 152 the optical axis 173 is changed to be perpendicular again. It is delivered to the CCD camera 160 horizontally to the ground. The image of the observation object transmitted along the traveling directions of the optical axes 172, 173, and 174 is captured by the CCD camera 160 and converted into a signal.

These signals are edited on the USB board 162 and sent to the computer through the USB terminal 164 of the signal splitter 163, and the TV is connected through the TV terminal 165 and the S terminal 166 of the signal splitter 163, respectively. Or it is transmitted to an external monitor and the image of the object to be observed is shown. In addition, when the image of the observation target is to be recorded, the CCD camera 160 captures and stores the screen.

When the objective lens 140 is inconsistent with respect to the object to be observed and the image is not clear, the focusing levers 131, 132, and 133 are operated to adjust the position of the specimen pedestal 130.

In addition, when the observation object and the optical axis 172 do not match and the image is not clear, the lamp adjuster 113 is rotated to adjust the optical axis 171 scanned from the light source lamp 111.

As described in detail above, the microscope equipped with the digital imaging means of the present invention incorporates a USB board and a CCD camera in a housing, and the components of the microscope are not positioned in a straight line of the optical axis scanned from the light source lamp. Since the direction of travel is changed, there is an effect of miniaturization compared to the microscope of the prior art.

In addition, the present invention has an advantage that the traveling direction of the optical axis is changed not only in the vertical direction but also in the horizontal direction, so that it is manufactured and transported in a stable rectangular miniaturized shape.

In addition, since the present invention can adjust the optical axis scanned from the light source lamp, there is an advantage to see a clear image of the observation target.

Although the technical idea of the microscope equipped with the digital imaging means of the present invention has been described together with the accompanying drawings, this is illustrative of the best embodiment of the present invention and is not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
