Description

  The present invention relates to a microscope that includes a main body and a stand, and the sample can be observed by removing the main body from the stand.

  Conventionally, a microscope called a digital microscope is known. A digital microscope is a microscope composed of a cylindrical main body and a stand that mechanically holds the main body. The main body has an optical system including an objective lens and the like, and observation light from a sample guided by the optical system. CCD (Charge Coupled Devices) is provided.

  When observing a sample with a digital microscope, a controller for controlling the operation of the main body and a monitor for displaying an observation image of the sample imaged by the CCD are connected to the main body by a cable. Then, depending on the sample to be observed, observation is performed with the main body removed from the stand or with the main body attached to the stand.

  For example, when observation is performed with the main body removed from the stand, the spectroscope holds the main body with a hand and approaches the desired part of the sample to observe the sample. In this case, the observation image picked up by the CCD is displayed on a monitor connected to the main body. Thus, if a digital microscope is utilized, it can observe reliably (for example, refer patent document 1).

  The spectrographer can also display information indicating the observation image recorded in the memory 38, for example, a file name, a thumbnail image, and the observation image itself on the monitor 12 by operating the touch panel of the monitor 12.

  Next, with reference to FIG. 2 and FIG. 3, mechanical connection and electrical connection between the main body 21 and the stand 22 will be described.

  FIG. 2 is an arrow view when the microscope 11 is viewed from the direction of the arrow A in FIG. That is, FIG. 2 is a cross-sectional view of the microscope 11 at the position of the clamp 46 when the microscope 11 is viewed from above (in the direction of the CCD 36) to below (in the direction of the objective lens 33).

  The main body 21 and the stand 22 are mechanically connected also by the connector 45 described above. However, the mechanical connection between the main body 21 and the stand 22 is mainly performed by the female ant 81 provided on the main body 21 and the arm 48. This is done by the male ant 82 provided.

  That is, a long groove is provided in the depth direction in FIG. 2, that is, the longitudinal direction of the stand 22 in FIG. 1 (hereinafter also referred to as the Z direction) in FIG. Yes. In addition, on the surface of the arm 48 that comes into contact with the main body 21, a long projecting portion in the Z direction that fits the female ant 81 is formed as a male ant 82.

  When the main body 21 and the stand 22 are mechanically connected, the spectroscope is in a state where the female ant 81 and the male ant 82 are fitted so that the main body 21 is in a desired position. Is aligned with the stand 22 in the Z direction. Further, when the main body 21 is in a desired position, the examiner presses the female ant 81 part of the main body 21 against the male ant 82 part of the arm 48 by the rod-shaped clamp 46 to fix the main body 21 to the arm 48. In this way, the main body 21 is mechanically connected to the stand 22. The clamp 46 may have a screw structure such as a set screw.

  Further, in the microscope 11, as shown in FIG. 3, the main body 21 is mechanically connected (fixed) to the stand 22, and at the same time, the main body 21 and the stand 22 are electrically connected. . 3 is an arrow view when the microscope 11 is viewed from the direction of arrow B in FIG. That is, FIG. 3 is a cross-sectional view of the microscope 11 at a position near the small monitor 37 when the microscope 11 is viewed from above (in the direction of the CCD 36) to below (in the direction of the objective lens 33).

  The connector 45 is provided in the microscope 11 so that when the main body 21 and the arm 48 are mechanically connected, the connector 45-1 and the connector 45-2 are also mechanically connected. ing. When the connectors 45 are mechanically connected to each other, power supply lines provided on the main body 21 and the stand 22, lines connecting the control board 43 and the control board 54, and the like are connected to each other. And the stand 22 are also electrically connected. That is, the main body 21 and the stand 22 are mechanically and electrically connected by so-called one action.

  Therefore, the spectrographer simply connects the main body 21 and the stand 22 both mechanically and electrically without being particularly conscious of the mechanical and electrical connection simply by fixing the main body 21 to the arm 48. can do.

  Further, when the main body 21 is fixed to the arm 48, for some reason, the connector 45-1 of the main body 21 is perpendicular to the Z direction with respect to the connector 45-2 of the stand 22, that is, the vertical direction in FIG. Further, there is a possibility of shifting in the lateral direction (hereinafter also referred to as XY direction).

  Therefore, considering the position adjustment of the main body 21 in the Z direction and the displacement of the main body 21 in the XY direction, for example, a function that allows the connector 45 to allow a slight displacement in the Z direction and the XY direction using a spring or the like. It is desirable to have it. Further, the connector 45 may be held by a mechanical component, and a mechanism that allows the connector 45 to be displaced may be provided in the mechanical component.

  The main body 21 and the arm 48 have been described as being connected by the female ant 81 and the male ant 82 using the ant shape, but the position of the main body 21 relative to the arm 48 can be adjusted in the Z direction and the XY direction. 21 and the stand 22 may be connected in any way as long as they can be mechanically and electrically connected simultaneously. For example, the main body 21 and the stand 22 may be connected using a fitting such as a round bar or a rectangular guide shape.

  The main body 21 includes an LED 32 as a light source, an objective lens 33 to an imaging optical system 35 for forming an image of the sample 13, a CCD 36 for capturing an observation image, a small monitor 37 for displaying the observation image, and a main body. A battery 44 is provided to supply power to each unit 21. Therefore, the spectrographer can remove the main body 21 from the stand 22 and observe the sample 13 using the main body 21 as a single microscope as shown in FIG.

  When the main body 21 is separated from the stand 22, the control board 43 switches the power supply source to the main body 21 from the stand 22 (power supply unit 52) to the battery 44, and the observation image supply destination is also from the stand 22. Switch to small monitor 37. Thereby, the main body 21 functions as a microscope alone, and an observation image is displayed on the small monitor 37.

  The spectroscope holds the main body 21 by hand and points the objective lens 33 of the main body 21 toward the sample 13 so that a desired part of the sample 13 can be observed. Then, since the observation image of the part of the sample 13 close to the main body 21 is displayed on the small monitor 37, the spectroscope looks at the displayed observation image or operates the capture button 41 to display the observation image. The sample 13 is observed by capturing. Although not shown in the figure, the main body 21 may be formed with a gripping portion provided so as to protrude from the main body 21. Further, if the capture button 41 is arranged on the grip portion, the operability can be further improved.

  Further, when the spectrographer wants to display the observation image and the state information on the small monitor 37, he / she operates the switching button 42 to display the state information on the small monitor 37. Specifically, the state information includes the zoom magnification of the zoom optical system 34, the amount of illumination light from the LED 32, the numerical aperture (NA (numerical aperture)) of the objective lens 33 and the zoom optical system 34, and the like. The observation conditions, the remaining capacity of the battery 44, the free capacity of the memory 38, and the like.

  For example, when the zoom switch 39 or the dimming switch 40 is operated, a signal corresponding to the operation is supplied from the zoom switch 39 or the dimming switch 40 to the control board 43. Further, when the zoom switch 50 or the dimming switch 51 is operated, signals corresponding to those operations are supplied from the control board 54 to the control board 43. Therefore, the control board 43 can obtain the zoom magnification of the zoom optical system 34 as the state information and the amount of illumination light, that is, the brightness, from the signals supplied from the zoom switch 39 and the control board 54.

  Further, for example, the control board 43 can obtain the free capacity of the memory 38 and the remaining power of the battery 44 as status information by accessing the memory 38 or applying a load to the battery 44. . The control board 43 supplies the state information obtained in this way to the small monitor 37 for display.

  The status information includes information such as whether the normal mode for capturing an observation image with normal settings or the high-definition mode for capturing a higher-definition observation image by narrowing the aperture of the zoom optical system 34 or the like. It may be displayed on the small monitor 37.

  Thus, in the microscope 11, when the main body 21 is detached from the stand 22, the main body 21 functions as a microscope alone, so that the sample 13 can be easily connected without connecting a monitor or a controller to the main body 21 with a cable or the like. Can be observed. Thereby, the convenience of the microscope 11 can be improved.

  By the way, when the power source of the microscope 11 is turned on and power is supplied to each part of the microscope 11, the microscope 11 starts an observation process, which is a process of imaging the sample 13 and displaying an observation image. Hereinafter, the observation process by the microscope 11 will be described with reference to the flowchart of FIG.

  In step S <b> 11, the control board 43 determines whether the main body 21 is electrically connected to the stand 22.

  For example, whether or not the main body 21 is connected to the stand 22 is detected by a mechanical switch or sensor (not shown) provided on the connector 45. Further, for example, when the main body 21 and the stand 22 are electrically connected, a mechanism for supplying a signal indicating that the main board 21 and the stand 22 are connected to the control board 43 is provided in the microscope 11. The connection with the stand 22 may be detected by the mechanism.

  If it is determined in step S <b> 11 that the main body 21 is connected to the stand 22, the control board 43 selects the power supply unit 52 of the stand 22 as a power supply source to the main body 21 in step S <b> 12.

  Then, the control board 43 instructs the control board 54 to supply power from the power supply unit 52 via the connector 45. Then, the control board 54 controls the operation of the power feeding unit 52 in accordance with an instruction from the control board 43, and the power feeding part 52 supplies power from an external power source via the connector 45 according to the control of the control board 54. Supply to each part.

  In step S <b> 13, the charging unit 53 of the power feeding unit 52 supplies power to the battery 44 via the connector 45 to charge the battery 44. Thereby, the spectrographer can charge the battery 44 without removing it from the main body 21. However, this charging operation is not essential, and charging can be performed with an external charger.

  In step S14, the control board 43 selects the stand 22 as the observation image supply destination. As a result, the observation image is displayed on the monitor 12.

  In step S <b> 15, the microscope 11 captures an observation image of the sample 13. That is, the control board 43 controls the LED 32 to irradiate the sample 13 with illumination light. Then, the illumination light from the LED 32 is irradiated onto the sample 13, whereby the observation light from the sample 13 enters the CCD 36 through the objective lens 33, the zoom optical system 34, and the imaging optical system 35. The CCD 36 picks up an observation image by receiving incident observation light and performing photoelectric conversion. The observation image of each frame as a moving image obtained in this way is supplied from the CCD 36 to the control board 43.

  In step S <b> 16, the control board 54 displays an observation image on the monitor 12. That is, the control board 43 supplies the observation image supplied from the CCD 36 to the control board 54 of the stand 22 through the connector 45. Then, the control board 54 supplies the observation image from the control board 43 to the monitor 12 for display.

  As a result, the spectroscope can observe the sample 13 by viewing the observation image displayed on the monitor 12. For example, if the monitor 12 having a display unit (higher resolution) than the small monitor 37 is connected to the stand 22, the observation image can be displayed larger and clearer for observation.

  In step S <b> 17, the control board 43 supplies state information indicating the state of the main body 21 to the small monitor 37 for display. Thereby, the spectroscope looks at the observation image displayed on the monitor 12 and observes the sample 13, while viewing the state information displayed on the small monitor 37 as necessary, and the zoom magnification of the zoom optical system 34 The state of the main body 21 can be known.

  For example, in the example of FIG. 1, an observation image of the sample 13 is displayed on the monitor 12, and the character “zoom 8.5 ×” indicating the zoom magnification of the zoom optical system 34 and the illumination light are displayed on the small monitor 37 as state information. The text “Light 70%” indicating brightness is displayed.

  In this way, by mounting the main body 21 on the stand 22 and displaying the observation image on the monitor 12, if the state information is displayed on the small monitor 37 that does not need to display the observation image, the state information can be more easily viewed. Can be presented to the person. In addition, since it is not necessary to superimpose and display the state information on the observation image of the monitor 12, the observation image can be easily seen. In addition, the display unit of the small monitor 37 is attached to the main body 21 with a hinge or the like, and the direction of the display unit with respect to the main body 21 is made variable so that when the main body 21 is attached to the stand 22, the display unit is placed on the spectroscope side. It is more effective to face it.

  Although it has been described that the state information is displayed on the small monitor 37 when the main body 21 is electrically connected to the stand 22, the small monitor 37 may be turned off, and the observation image is displayed on the small monitor 37. And state information may be displayed in a superimposed manner.

  In addition, when the spectrographer wants to simultaneously display the observation image and the state information on the monitor 12, he / she operates the touch panel superimposed on the monitor 12 to instruct the display of the state information on the observation image. Can do. When the spectroscope operates the touch panel to instruct superposition display of the state information, a signal corresponding to the operation is supplied from the touch panel (monitor 12) to the control board 54. Alternatively, a state display dedicated area may be provided on the lower side, left side, right side, upper side, or the like of the display unit so that the status is always displayed.

  In step S <b> 18, the control board 54 determines whether or not to display status information on the monitor 12 based on a signal supplied from the touch panel of the monitor 12. For example, when a signal instructing to superimpose the state information on the observation image on the monitor 12 is supplied from the touch panel to the control board 54, it is determined that the state information is displayed.

  When it is determined in step S18 that the status information is displayed on the monitor 12, the control board 54 causes the monitor 12 to display the status information in step S19. That is, the control board 54 requests the control board 43 to supply state information. Then, since the control board 43 supplies the state information to the control board 54 via the connector 45, the control board 54 supplies the state information from the control board 43 to the monitor 12 and superimposes the state information on the observation image. To display.

  As a result, the observation image and the state information are simultaneously displayed on the monitor 12. In the state in which the state information is displayed on the monitor 12, it is not always necessary to display the state information on the small monitor 37 of the main body 21, so the small monitor 37 may be turned off. When the status information is displayed on the monitor 12, the process proceeds to step S20.

  If it is determined in step S18 that the status information is not displayed on the monitor 12, the process of step S19 is not performed, and the process proceeds to step S20.

  If it is determined in step S18 that the status information is not displayed on the monitor 12, or if the status information is displayed on the monitor 12 in step S19, in step S20, the control board 43 determines whether or not an instruction to capture the observation image has been issued. Determine whether.

  That is, the control board 43 instructs to capture the observation image based on the signal supplied from the capture button 41 or the signal supplied from the control board 54 according to the operation of the spectroscope on the touch panel of the monitor 12. It is determined whether or not it has been done.

  If it is determined in step S20 that capture has been instructed, the control board 43 captures the observation image supplied from the CCD 36 in step S21. Then, the control board 43 supplies an observation image as a still image obtained by capture to the memory 38 for recording, and the process proceeds to step S22.

  Note that the captured observation image may be displayed not only on the memory 38 but also on the monitor 12.

  On the other hand, when it is determined in step S20 that capture has not been instructed, the process of step S21 is not performed, and the process proceeds to step S22.

  If it is determined in step S20 that capture has not been instructed, or if an observation image is captured in step S21, in step S22, the control board 43 determines whether an operation on the optical system of the microscope 11 has been performed.

  For example, when a signal corresponding to the operation of the spectroscope is supplied from the zoom switch 39 or the light control switch 40 to the control board 43, or a signal corresponding to the operation on the zoom switch 50 or the light control switch 51 is When supplied to the control board 43 from 54, it is determined that an operation on the optical system has been performed.

  If it is determined in step S22 that an operation has been performed on the optical system, in step S23, the control board 43 performs a process according to the operation of the spectrographer, and then the process proceeds to step S24.

  For example, when the zoom switch 39 or the zoom switch 50 is operated, the control board 43 controls a driving circuit (not shown) to move the lens constituting the zoom optical system 34 and increase the zoom magnification of the zoom optical system 34. Change it. For example, when the dimming switch 40 or the dimming switch 51 is operated, the control board 43 controls the LED 32 to change the amount of illumination light from the LED 32.

  On the other hand, if it is determined in step S22 that no operation has been performed on the optical system, the process of step S23 is not performed, and the process proceeds to step S24.

  If it is determined in step S22 that no operation has been performed, or if processing according to the operation is performed in step S23, the control board 43 determines in step S24 whether to turn off the power of the microscope 11. For example, when a power switch (not shown) is operated by the spectrograph and an instruction to turn off the microscope 11 is given, it is determined that the power is turned off.

  If it is determined in step S24 that the power is not turned off, the sample 13 is continuously observed, so the processing returns to step S11 and the above-described processing is repeated.

  On the other hand, when it is determined in step S24 that the power supply is turned off, the control board 43 and the control board 54 turn off the power supply of the microscope 11 and the observation process ends.

  When it is determined in step S11 that the main body 21 is not connected to the stand 22, the control board 43 selects the battery 44 on the main body 21 side as a power supply source to the main body 21 in step S25. That is, the control board 43 controls the battery 44 to supply power to each part of the main body 21.

  Thereby, the main body 21 can function as a microscope alone. When the main body 21 is removed from the stand 22, as described with reference to FIG. 4, the spectroscope holds the main body 21 in the hand and observes the sample 13.

  In step S26, the control board 43 selects the main body 21 as the observation image supply destination. As a result, the observation image is displayed on the small monitor 37. In step S27, the microscope 11 captures an observation image of the sample 13. In step S27, processing similar to that in step S15 is performed.

  In step S28, the control board 43 supplies the observation image supplied from the CCD 36 to the small monitor 37 for display.

  In step S <b> 29, the control board 43 determines whether or not to display state information on the small monitor 37. For example, when the switch button 42 is operated by the spectrographer and the switch button 42 is in a state of supplying a signal for displaying the state information to the control board 43, it is determined that the state information is displayed. .

  If it is determined in step S29 that state information is to be displayed, in step S30, the control board 43 supplies the state information to the small monitor 37 for display. Thereby, the state information is superimposed on the observation image and displayed on the small monitor 37.

  When the observation image and the state information are displayed on the small monitor 37, the process thereafter proceeds to step S20, and the above-described process is repeated.

  On the other hand, if it is determined in step S29 that the state information is not displayed, the process of step S30 is not performed, the process proceeds to step S20, and the above-described process is repeated.

  As described above, the microscope 11 improves the convenience of the microscope 11 by switching the power supply source and the display of the observation image according to whether or not the main body 21 and the stand 22 are connected. Can do.

  For example, when the main body 21 is attached to the stand 22, it is possible to suppress the consumption of the battery 44 on the main body 21 side by supplying power to the main body 21 from the outside. Therefore, the spectrographer can use the main body 21 for a longer time when the main body 21 is removed from the stand 22.

  When the main body 21 is attached to the stand 22, the observation image is displayed on the monitor 12 and the state information is displayed on the small monitor 37, so that the observation image and the state information are displayed more easily. Can do.

  Further, in the microscope 11, when the main body 21 is detached from the stand 22, the main body 21 functions as a microscope alone, and when the main body 21 is mechanically connected to the stand 22, it is electrically connected simultaneously. Is also connected, so the convenience and the observation environment of the sample 13 can be improved.

  For example, when the main body 21 is detached from the stand 22, it is not necessary to connect a monitor or a controller to the main body 21 with a cable or the like by allowing the main body 21 to function as a microscope alone, and convenience is improved. That is, the spectrographer can start observation simply and quickly by simply removing the main body 21 from the stand 22 without carrying the controller or the monitor. At this time, displaying the enlarged image of the sample under observation on the small monitor 37 improves the usability of the spectroscope.

  When the main body 21 is attached to the stand 22 and the sample 13 is observed, if the main body 21 and the stand 22 are mechanically connected, the main body 21 and the stand 22 are also electrically connected at the same time. And the stand 22 need not be connected to each other by a cable. Moreover, since there is no need to connect a device such as a monitor to the main body 21, workability does not deteriorate due to troublesome cable routing.

  Further, in the microscope 11, since there is no need to connect other devices to the main body 21 with a cable or the like, the main body 21 fixed to the stand 22 does not vibrate due to the shaking of the cable, etc. It can be observed in a better environment. That is, the observation environment of the sample 13 can be improved.

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
