38d.

Next, the relay lens device configured as described above will be described in more detail.

First, the optical path for observing the specimen S is determined by operating the prism 12 of the microscope main body 1. In this case, when the prism 12 is mounted in the observation lens barrel 8, the observation optical path 14
Is selected, and the sample image is observed through the eyepiece 13. When the prism 12 is removed from the observation lens barrel 8, the observation optical path 15 is selected, and the liquid crystal monitor 32 on which the sample image is captured by the image sensor array 21 of the camera body 16.
Alternatively, it is displayed on the external monitor device 6.

In this way, the observation optical path 14 or 15
Is determined, the stage 11 is adjusted so that the sample image is at a desired position in the observation visual field, and the revolver 9 is rotated so as to obtain a desired magnification, thereby obtaining the objective lens 10.
Select

Next, a case where a sample image is photographed using the camera body 16 will be described. In this case, the observation optical path 15 is selected by removing the prism 12 from the inside of the observation lens barrel 8 as described above. Then, the sample image from the microscope main body 1 is taken into the camera main body 16 via the relay lens device 2 and imaged by the image sensor array 21 so that the liquid crystal monitor 3
2 or the external monitor 6.

In this state, if the shutter switch 34 of the camera body 16 is operated, the specimen image can be photographed. Prior to this photographing, the position and size of the specimen image to be noticed, and the microscope body 1 In order to superimpose and record various information such as the setting state of, for example, the used magnification of the objective lens, the insertion filter, and the color temperature of the light source, the following operation is performed.

In this case, the image of the sample image picked up by the image pickup element array 21 is displayed on the liquid crystal monitor 32 or the external monitor device 6. Operate 37. Here, assuming that the key 37b corresponds to the arrow b shown in FIG. 3B, when the key 37b is pressed, the display information corresponding to the arrow b is displayed from the display information storage ROM 38c of the information generating unit 38. After being read out and temporarily stored in the display RAM 38b, the liquid crystal display member 3 is connected via the display IC 38d.
5 is displayed as an arrow b shown in FIG. Thereby, the arrow b of the display information displayed on the liquid crystal display member 35 is imaged by the image sensor array 21 together with the sample image, and is displayed on the liquid crystal monitor 32 or the external monitor device 6.
The specimen image and the image of the arrow b are displayed in a superimposed state.

When it is desired to move the arrow b to a predetermined position in the observation image, the cross direction switch 37g is operated to move the position of the arrow b displayed on the liquid crystal display member 35 up, down, left and right. Thereby, the display position of the arrow b on the display image of the liquid crystal monitor 32 or the external monitor device 6 can be arbitrarily changed, so that the point of interest of the sample image or the like can be indicated by the arrow b.

When the shutter switch 34 of the camera body 16 is operated in this state, the camera body 16 takes the specimen image and the image indicated by the arrow b in a superimposed manner.

Next, assuming that the key 37a corresponds to the scale a shown in FIG. 3A, when the key 37a is depressed, the display information storage ROM 38c of the information generating unit 38
After the display information corresponding to the scale a is read out and temporarily stored in the display RAM 38b, the display IC 38d is read out.
Is transferred to the liquid crystal display member 35 via the interface, and the scale a shown in FIG. 3A is displayed. In this case, the value of the scale a changes depending on the magnification of the objective lens 10 switched on the optical path by the revolver 9 and the like.
Must be selected.

Here, the scale a is an index of the size of the sample image to be photographed, and its value differs depending on the magnification of the objective lens 10 and the like. That is, the magnification that determines the value of the scale a is determined by the magnification by the relay lenses 26 and 27 and the magnification by the camera body 16 in addition to the magnification by the objective lens 10. Therefore, the combination of these magnifications and the value of the scale a determined by the magnification at this time are stored in the display information storage ROM 38c in advance.

In this case, the value Sv of the scale a according to the magnification
al is the magnification by the objective lens 10 Nobj, the magnification by the relay lenses 26 and 27 is Nrel, and the camera body 1
6 is Ncam, and the scale width ratio with respect to the observation visual field is Srate, Sval = Slate / (N
obj × Nrel × Ncam) × n. Where n
Indicates the size of the observation visual field. In this case, Nre in the equation
Since l and Ncam are considered to be constant, the value of the scale a is determined by the magnification of the objective lens 10. Therefore, the value of the scale a is calculated by the above equation for each magnification of the objective lens 10 mounted on the revolver 9 and stored in the display information storage ROM 38c.

From the above, in order to change the value of the scale a displayed on the liquid crystal display member 35 by switching the objective lens 10, the value of C is changed in conjunction with the operation of the cross direction switch 37g.
The value of the scale a corresponding to the magnification at this time is acquired from the display information storage ROM 38c from the PU 38a, and the display R
After being temporarily stored in the AM 38b, the data is transferred to the liquid crystal display member 35 via the display IC 38d, and is displayed on the liquid crystal display member 35. In this case, the cross direction switch 3 by the observer
The display position and display direction of the scale a can be changed by the operation of 7g.

Similarly, assuming that the key 37c corresponds to the frame c shown in FIG.
Is pressed, the display information storage ROM of the information generation unit 38 is pressed.
The display information corresponding to the frame c is read out from the display RAM 38c and temporarily stored in the display RAM 38b.
The data is transferred to the liquid crystal display member 35 via C38d,
The frame c shown in (c) is displayed.

Further, assuming that the keys 37d to 37f correspond to the display of the magnification of the objective lens 10, the type of the insertion filter, the color temperature of the light source, and the like, these keys 37d to 37f are displayed.
When is pressed, information display of the objective lens magnification, the insertion filter type, and the light source color temperature is displayed on the liquid crystal display member 35 in accordance with the operation of these keys 37d to 37f. In this case, by operating the cross direction switch 37g, the magnification of the objective lens can be selected, and the type of the insertion filter and the color temperature of the light source can be selected according to the state of the microscope.

When the display erasure switch 37h is pressed, all information displayed on the liquid crystal display member 35 can be erased. In this state, only observation and photographing of the sample image with no information displayed can be performed.

Therefore, according to this configuration, the content of the display information displayed on the liquid crystal display member 35 mounted on the relay lens device 2 is controlled by the information control section 31, so that the information is controlled together with the sample image. Information to be imprinted can be set by a simple operation. In addition, the liquid crystal display member 35
Since it is installed in the relay lens device 2 provided between the microscope main body 1 and the camera main body 16, the entire configuration is simple, and the liquid crystal display member 35 for displaying information on the camera main body 16 and the microscope main body 1 is specially provided. Since the camera body 16 and the microscope body 1 need not be provided at low cost, it is possible to use inexpensive ones for the camera body 16 and the microscope body 1, and the cost can be reduced. Further, by using the liquid crystal display member 35, even in a case where no information is displayed or a case where information is displayed, a sample image can be transmitted through the camera body 16 in an area where there is no display information such as characters. Furthermore, since various kinds of information displayed on the liquid crystal display member 35 can be imprinted on the photographed image, there is no need for the observer to memorize the information by taking notes, and the workability of the microscope can be improved. it can.

In the above-described first embodiment, an example is described in which the information control unit 3 and the relay lens device 2 are provided separately. For example, as shown in FIG.
1 may be configured integrally with the relay lens device 2. In this case, in FIG. 4, the same parts as those in FIG. 2 are denoted by the same reference numerals.

In this manner, the cable 30 required for electrically connecting the relay lens device 2 and the information control unit 31 can be omitted, so that operation on a desk with limited space can be performed by the cable 30. You can do it easily without disturbing you. Further, a zoom lens may be arranged in the observation optical path 15 of the microscope main body 1. This makes it possible to arbitrarily change the magnification of the sample image by driving the zoom lens without changing the magnification of the objective lens 10.

(Second Embodiment) FIG. 5 shows a schematic configuration of a main part of a second embodiment of the present invention, and the same parts as those in FIG. 2 are denoted by the same reference numerals.

In this case, a microscope control section 41 is connected to the microscope main body 1, and the information control section 31 is connected to the microscope control section 41.

The microscope control unit 41 includes a revolver control switch 41 a, a CPU 41 b that monitors input from the revolver control switch 41 a and performs revolver drive control, and a communication control for exchanging data with the information control unit 31 via the cable 42. The unit 41c includes a revolver driving unit 43 provided on the microscope main body 1 side and a microscope communication control unit 41d for exchanging data via a cable 44.

In such a configuration, the electric control of the revolver 9 of the microscope main body 1 is as follows. First, when the observer presses the revolver control switch 41a, the CPU 41
The push-down state signal is sent to b. The CPU 41b transmits a drive signal to the revolver drive unit 43 by the microscope communication control unit 41d so as to drive and control the revolver 9 clockwise to the next objective lens position by pressing the revolver control switch 41a once. The revolver driving unit 43 controls the driving of the revolver 9 by a predetermined distance based on the received driving signal.

Since the control state of the microscope main body 1 by the microscope control unit 41 is grasped by the information control unit 31 via the communication control unit 41c, the control state at this time is sampled by the information control unit 31 together with the sample image. It can also be displayed. For example, when the magnification of the objective lens 10 is displayed by pressing the key 37d of the key input unit 37, the key 3 is used.
7d, the information control unit 31 sets the microscope control unit 4
By acquiring the switching information of the objective lens 10 by communicating with 1, the objective lens magnification can be displayed on the liquid crystal display member 35 based on this information.

In this way, the operation for displaying the state of the microscope main body 1 on the liquid crystal display member 35 is simplified, and the operability is improved. In addition, since the control state of the microscope main body 1 by the microscope control unit 41 can be displayed on the liquid crystal display member 35 one by one, it is possible to minimize an information input error by the observer. In addition, the liquid crystal display member 35 provided in the relay lens device 2 can display information desired to be displayed at an arbitrary position in the entire observation range because the displayable range covers the entire observation range. And display information can be minimized,
Shooting evaluation can be performed easily.

In the above-described second embodiment, an example has been described in which the microscope control unit 41 and the information control unit 31 are provided separately. For example, as shown in FIG. The information control unit 31 may be integrally configured. In this case, in FIG. 6, the same parts as those in FIG. 5 are denoted by the same reference numerals.

In this way, since the microscope control and the control of the display information can be performed at one place, the operability is improved, and the desk space is increased, and the workability can be expected to be improved.

(Third Embodiment) FIG. 7 shows a schematic configuration of a main part of a third embodiment of the present invention, and the same parts as those in FIG. 2 are denoted by the same reference numerals.

In this case, the camera body 16 attached to the relay lens device 2 enables the video output from the video signal output terminal 33 to be input to the information control unit 31. The information control unit 31 includes an image processing circuit 38e in the information generation unit 38 as shown in FIG.
The video output from the CPU is image-processed and then input to the CPU 38a.

With such a configuration, the camera body 16
Can be input to the information control section 31, so that the image recorded in the camera body 16 can be reproduced and the reproduced image can be displayed on the liquid crystal display member 35 together with the observation image. FIG. 8 shows an example of an observation image. In the figure, an image A in which "LIVE" is displayed is a current observation image, and an image B in which "PLAY" is displayed is a reproduced image.

After operating a menu key (not shown),
By operating the cross direction stitch 37g, the image A displaying “LIVE” and the “PLAY” as shown in FIG.
Can be displayed by reversing the positional relationship of the image B displayed. Further, as shown in FIG.
An image A on which "E" is displayed and an image B on which "PLAY" is displayed can also be displayed on the left and right halves.

Further, when the displayable range of the liquid crystal display member 35 covers the entire observation range, first, the sample image C as shown in FIG.
Is taken, and after a lapse of a certain period of time, the sample image taken earlier is displayed on the liquid crystal display member 35 as a reproduced image C ′ as shown in FIG. Can be photographed by the camera body 16 in a superimposed manner on the observation image of FIG.

In this way, it is possible to compare and observe the state of the sample, which changes over time.

In the third embodiment, the information control section 31 is connected to the video signal output terminal 33 of the camera body 16.
However, as shown in FIG. 12, an information controller 31 having an information analyzer 52 may be connected to a communication terminal 51 of the camera body 16. Here, the communication terminal 51 includes not only image information captured by the camera body 16 but also various information such as data in an image information header area in which shooting conditions and the like of the captured image are recorded and a setting state of the camera body 16. Is output. The information analyzer 52 reads and analyzes data in the image information header area input from the communication terminal 51.

In this manner, various information output from the communication terminal 51 is transmitted from the information analysis section 52 to the information control section 31.
, The settings of the camera body 16 and the microscope body 1 can be controlled based on the result analyzed by the information analysis unit 52. Now, the communication terminal 5 of the camera body 16
When the reproduced image is output from the device 1, the reproduced image is input to the information analysis unit 52 of the information control unit 31. The information control section 31 reads the information header area of the input reproduced image.
If the readout information includes a photographing condition, for example, a shutter speed of the camera body 16 and an objective lens magnification, the camera body 16 is set to be equal to the value written via the CPU 38a. And the microscope body 1 can be controlled. If the information control unit 31 controls the camera, the camera body 16 can be operated without touching the camera.

Therefore, from these facts, it becomes easy to read out the photographing conditions and the like from the reproduced image, so that an improvement in the photographing efficiency can be expected. In addition, there is no need to save the settings of the camera main body 16 and the microscope main body 1 in a memo or the like, so that the microscopic work can be performed smoothly.

(Fourth Embodiment) Next, a fourth embodiment will be described.

In this case, in FIG. 2, a liquid crystal display member 35 provided in the relay lens device 2 is used so that its displayable range can cover the entire observation range. The amount of transmitted light at 35 can be adjusted. In this case, the liquid crystal display member 35 has a very small display dot size (very high dot density), so that each dot is ON / OFF (transmission / blocking) control. Also, the control of the overall transmitted light amount can be performed in a pseudo manner. Further, it is of course possible to use a display element that can control the amount of transmitted light in dot units. Other configurations are the same as those in FIG. 2, and details will be described with reference to FIG.

In this way, the amount of light transmitted through the liquid crystal display member 35 by the information control unit 31 is appropriately adjusted, so that the amount of incident sample light on the camera body 16 can be adjusted. That is, in taking a micrograph, a shutter speed often requiring a shutter speed shorter than 1/5000 second is required, but a high-speed shutter operation such as 1/5000 or 1/10000 is required to accurately and quickly operate the shutter element. Driving is required and it is expensive. On the other hand, the camera body 16
In such a case, a high-speed shutter is not necessarily provided for cost reduction, and the camera body 16 may be overexposed even if the observer determines that the amount of light is appropriate by observation with the eyepiece 13. In such a case, if the amount of transmitted light of the liquid crystal display member 35 is appropriately adjusted by the information control unit 31,
Since the filter operates as a neutral density filter for appropriately adjusting the amount of light incident on the camera body 16 while keeping the amount of light for observation with the eyepiece lens 13 at an appropriate level, the shutter speed at the camera body 16 is set to 1/1000 or 1/500. It can be kept relatively low. As a result, the camera body 16 does not need to be equipped with an expensive high-speed shutter, and can be reduced in cost.

In the fourth embodiment, as shown in FIG. 12, the information control section 31 having the information analysis section 52 is connected to the communication terminal 51 of the camera body 16. Applicable. In this case, the liquid crystal display member 3
The adjustment of the transmitted light amount of the communication terminal 5 is performed by the communication terminal 51 of the camera body 16.
Is controlled based on the information obtained from.

The present invention is not limited to the above-described embodiments, and can be appropriately modified and implemented without departing from the scope of the invention.

For example, as shown in FIG. 13, the microscope controller 41 and the information controller 31 are integrated and the camera body 16
And a connection through the communication terminal 51. In this way, the microscope control and the information display control can be performed in one place using the information acquired from the camera body 16, and the camera body 16 can be controlled in conjunction with the microscope control and the information display control.
