Description

The present invention relates to a microscope , and more particularly to a microscope capable of improving the operability of an operation for moving an electric stage of the microscope, for example.

  As an electric stage control device for controlling the electric stage of the microscope, the electric stage is driven so that the electric stage moves at a predetermined direction and speed when the joystick is tilted from the neutral position (reference position) in a predetermined direction. A joystick controller for controlling a motor is known.

  According to the joystick controller, an observer who observes a specimen with a microscope operates a joystick to move the electric stage (hereinafter referred to as a moving direction) and the speed at which the electric stage moves (hereinafter referred to as a moving speed). Can also be instructed.

  That is, when the joystick of the joystick controller is tilted from the neutral position by the observer, the electric stage is tilted at an angle (neutral position) where the joystick is tilted in a direction corresponding to the direction in which the joystick is tilted (hereinafter referred to as the tilt direction). Is moved at a speed corresponding to the angle of the tilted joystick (hereinafter referred to as the tilt angle). In addition, the moving speed of the electric stage increases as the tilt angle of the joystick increases.

  Further, in Patent Document 1, the tilt of the operation lever is determined from the first region from the neutral position to the first tilt angle, the second region from the first tilt angle to the second tilt angle, and the second tilt angle. Separate from the third region up to the third tilt angle, the first region is a dead zone and the stage is not moved, and the second region is a stage that changes only in a predetermined relationship with the tilt angle so that fine adjustment is possible. A driving device is described in which the stage 3 is accelerated and the stage speed is changed to a predetermined speed at an accelerated speed (particularly, page 3, lower right column, line 19 to page 4 of Patent Document 1). (Upper left column, line 7).

  According to the above-described joystick controller and the driving device described in Patent Document 1, when a specimen is examined with a microscope, an observer first moves the electric stage in a direction in which the specimen on the electric stage enters the field of view of the microscope. As described above, the tilt direction of the joystick is determined, and the joystick is largely tilted in the tilt direction, and the electric stage is moved at a high speed. After the speculum part of the specimen enters the field of view, the observer adjusts the tilt angle of the joystick, for example, depending on the magnification of the microscope, Move the stage.

  However, in the joystick controller, the joystick has a return mechanism that returns to the neutral position when the external force is stopped, and the electric stage stops when the joystick returns to the neutral position. For this reason, when the observer releases his / her hand from the joystick, the joystick returns to the neutral position and the electric stage stops, so that the observer needs to move the joystick to move the electric stage at a constant speed. The tilt angle must be kept constant.

  Therefore, a Prior joystick controller having a return prohibiting switch that prohibits the joystick from returning to the neutral position is known as a joystick controller that can keep the tilt angle of the joystick at a constant angle.

  Prior's joystick controller has, as return prohibition switches, an X-axis return prohibition switch that prohibits return to the neutral position in the X-axis direction and a Y-axis return prohibition switch that prohibits return to the neutral position in the Y-axis direction . When the observer prohibits the return of the joystick by turning on the return prohibition switch, the joystick is fixed at the position when the return prohibition switch is turned on, and is constant according to the tilt angle and direction of the joystick. The electric stage continues to move at a speed and a constant direction.

JP 60-118819 A

  However, with the Prior joystick controller, in order to stop the motorized stage, the observer forcibly returns to the neutral position if the joystick is operated, or the X-axis return prohibition switch as a return prohibition switch. It is necessary to cancel the prohibition of returning the joystick by operating both the Y-axis return prohibiting switch and the Y-axis return prohibiting switch.

  Therefore, it is difficult to say that the operability when the electric stage moving at a constant speed is suddenly stopped is excellent.

  Furthermore, for example, it is difficult to say that the operability in the case of repeatedly moving the electric stage at a constant speed and repeatedly stopping it is good.

  The present invention has been made in view of such a situation, and is intended to improve the operability of an operation of moving an electric stage of a microscope.

A first microscope according to the present invention includes an operation member that instructs to move a stage on which an object is placed by operation, a control unit that controls movement of the stage in accordance with an operation of the operation member, and a first Setting means for setting a state or a second state, and when the setting means is in the first state, the control means has a speed according to an operation amount from a reference position of the operation member. The stage is controlled to move, and when the setting means is in the second state, the stage is controlled to move at a constant speed regardless of the operation amount from the reference position of the operation member. When the setting means is in the second state, the control means causes the stage to move at a speed at which the stage has moved when the setting means is switched to the second state. to and controls the .
The second microscope of the present invention comprises a control means for controlling the movement of the stage of installing the object to be observed, and the operation member for instructing the operation, the movement of the stage in response to operation of the operation member, the Setting means for setting the first state or the second state, and when the setting means is in the first state, the control means is a direction corresponding to the operation direction from the reference position of the operation member. controlling the stage to move in, the case where the setting means is in the second state, controlling the stage to move in a certain direction regardless of the operating direction from a reference position of the operating member When the setting means is in the second state, the control means moves the stage so that the stage moves in a direction in which the stage has moved when the setting means is switched to the second state. control to And features.

ADVANTAGE OF THE INVENTION According to this invention, the operativity of operation which moves the electric stage of a microscope can be improved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of an embodiment of an electric stage control system to which the present invention is applied.

  The electric stage control system 1 in FIG. 1 includes a microscope 11 and a joystick controller 12 as an electric stage controller connected to the microscope 11 via a cable.

  The microscope 11 includes an X-axis drive motor 31, a Y-axis drive motor 32, a Z-axis drive motor (Z-axis drive device) 33, an electric stage 34, and a vertical movement unit 35, in addition to an objective and an eyepiece.

  The X-axis drive motor 31 and the Y-axis drive motor 32 are motors that drive an electric stage 34 on which a specimen to be microscopically placed, and the electric stage 34 is moved in accordance with control from the joystick controller 12 in the figure. Move in the direction and the Y-axis direction.

  The Z-axis drive motor 33 is a motor that drives the vertical movement unit 35 that supports the electric stage 34, and moves the vertical movement unit 35 in the Z-axis direction in the drawing in accordance with control from the joystick controller 12. When the vertical movement unit 35 moves in the Z-axis direction, the electric stage 34 moves in the Z-axis direction together with the vertical movement unit 35.

  2A and 2B are a front view and a left side view showing an example of the external configuration of the joystick controller 12 shown in FIG.

  The joystick controller 12 is operated by, for example, an observer who observes a specimen with a microscope, and according to the operation, an X-axis drive motor (X-axis drive device) 31, a Y-axis drive motor (Y-axis drive device) 32, The electric stage 34 is moved by controlling the Z-axis drive motor 33.

  The joystick controller 12 has a substantially rectangular parallelepiped shape, and on the front thereof, a joystick 51, an XY speed fixing mode setting button 53, an XY direction fixing mode setting button 54, a three-stage Z speed switching button 56, an XY A fixed speed mode display section 57, an XY direction fixed mode display section 58, a three-stage XY speed display section 59, and a three-stage Z speed display section 60 are provided, and a Z operation dial is provided on the right side toward the joystick controller 12. 52 is provided.

  The joystick 51 can be tilted in an arbitrary direction from the neutral position by applying force to the observer, and moves the electric stage 34 in the X-axis direction and the Y-axis direction (hereinafter also referred to as the XY direction). To be operated.

  The joystick 51 returns to the neutral position when the observer stops applying force.

  The joystick 51 is provided with a three-stage XY speed switching dial 55 that can be rotated around the joystick 51 as a rotation axis.

  The three-stage XY speed switching dial 55 can be rotated to the first to third angles, and the speed of the joystick 51 with respect to the tilt angle is set at a speed corresponding to the first to third angles. Can be switched to a three-stage XY speed for moving the X in the XY direction.

  Here, as the three-stage XY speed, there are three XY speed small, medium XY speed, and large XY speed, and the three-stage XY speed switching dial 55 rotates to the first to third angles. When this is done, the speed becomes small in XY speed, medium in XY speed, and large in XY speed, respectively.

  When the XY speed is small, the speed according to the tilt angle of the joystick 51 is the slowest of the three levels, and the speed increases as the XY speed increases.

  The Z operation dial 52 can be operated to rotate about a direction perpendicular to the side surface of the joystick controller 12 as a rotation axis, and is operated when the vertical movement unit 35 (electric stage 34) is moved in the vertical direction (Z-axis direction). Is done. That is, when the Z operation dial 52 is rotated upward (for example, counterclockwise), the vertical movement unit 35 moves upward, and when the Z operation dial 52 is rotated downward (for example, clockwise) ), The vertical movement unit 35 moves downward.

  The XY speed fixed mode setting button 53 and the XY direction fixed mode setting button 54 can be turned on and off (setting switching when the electric stage 34 is moved by the joystick 51 is turned on or off). Each time it is pressed, it changes from the on state to the off state, or from the off state to the on state.

  When the XY speed fixed mode setting button 53 is in the on state, the movement speed mode (hereinafter, also referred to as speed mode) of the electric stage 34 is the XY speed fixed mode. When the XY speed fixed mode setting button 53 is in the OFF state, the speed mode is, for example, an XY speed variable mode as a mode other than the XY speed fixed mode.

  Here, in the XY speed fixing mode, the electric stage 34 is moved when the XY speed fixing mode setting button 53 is operated to be turned on regardless of the inclination angle at which the joystick 51 is inclined. The electric stage 34 moves at a speed (a constant speed). In the XY speed variable mode, the electric stage 34 moves at a speed according to the tilt angle of the joystick 51.

  When the XY direction fixed mode setting button 54 is in the ON state, the movement direction mode of the electric stage 34 in the X axis direction and the Y axis direction (hereinafter, also referred to as direction mode) is the XY direction fixed mode, which is the XY direction fixed mode. When the setting button 54 is in the off state, the direction mode is the XY direction variable mode.

  Here, in the XY direction fixed mode, regardless of the tilt direction of the joystick 51, the direction in which the electric stage 34 has moved when the XY direction fixed mode setting button 54 is operated to be in the ON state (a constant XY direction). The electric stage 34 moves in the direction). In the XY direction variable mode, the electric stage 34 moves in a direction corresponding to the tilt direction of the joystick 51.

  The three-stage Z speed switching button 56 is sequentially switched to the first to third states each time it is pressed. Further, when the three-stage Z speed switching button 56 is pressed in the third state, it switches to the first state.

  The three-stage Z speed switching button 56 switches the speed in the Z-axis direction to the three-stage Z speed corresponding to the first to third states by sequentially switching to the first to third states. Can do.

  The three-stage Z speed includes small Z speed, medium Z speed, and large Z speed, and the three-stage Z speed switching button 56 is in any one of the first to third states. , The speed becomes small Z speed, medium Z speed, and large Z speed, respectively.

In the Z speed small, at a constant speed V _Z1, Z in during the fast, at a speed V _Z1 of the faster constant speed V _Z2, Z in the speed-sized, fast than the speed V _Z2 constant speed The electric stages 34 move at V _Z3 , respectively.

  The XY speed fixing mode display unit 57 is a portion surrounding the periphery of the XY speed fixing mode setting button 53 that is turned on by an LED (Light Emitting Diode) (not shown), and the speed mode is the XY speed fixing mode. When the speed mode is not XY speed fixed mode, the light is turned off.

  The XY direction fixed mode display portion 58 is a portion surrounding the periphery of the XY direction fixed mode setting button 54 that is lit by an LED (not shown), and is lit when the direction mode is the XY direction fixed mode, and the direction mode is XY. Turns off when not in fixed direction mode.

  The three-stage XY speed display unit 59 includes LEDs 59a to 59c.

  The LED 59a is lit when the speed is XY speed, the LED 59b is lit when the speed is XY speed, and the LED 59c is lit when the speed is small XY speed. .

  The three-stage Z speed display unit 60 includes LEDs 60a to 60c.

  The LED 60a is lit when the speed is Z speed large, the LED 60b is lit when the speed is Z speed, and the LED 60c is lit when the speed is small Z speed. . In other cases than those described above, the three LEDs 60a to 60c are turned off.

  FIG. 3 is a block diagram showing an example of the electrical configuration of the electric stage control system 1 of FIG.

  In addition, in the figure, the same code | symbol is attached | subjected about the part corresponding to the case of FIG. 1 or FIG.

  The joystick controller 12 includes a storage unit 91, a RAM (Random Access Memory) 92, and a CPU (Central Processing Unit) 93 in addition to the joystick 51 to the three-stage Z speed display unit 60 described above.

  The storage unit 91 includes a so-called nonvolatile storage medium that is rewritable and can retain recorded contents even when the power is turned off. For example, a hard disk, a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), an MRAM (Magnetoresistive Random Access Memory (magnetoresistance memory)) or FeRAM (Ferroelectric Random Access Memory (ferroelectric memory)) or the like. The storage unit 91 stores programs and data for the CPU 93 to perform various processes. The program and data stored in the storage unit 91 can be upgraded by rewriting.

  The RAM 92 temporarily stores data during the processing when the CPU 93 performs various processing.

  The CPU 93 performs various processes by executing the program stored in the storage unit 91. That is, the CPU 93 displays the X-axis drive motor 31 to the Z-axis drive motor 33 and the XY speed fixed mode display unit 57 to the 3-step Z speed display according to the operation of the joystick 51 to the 3-step Z speed switching button 56. The unit 60 is controlled.

  The program executed by the CPU 93 is stored in the storage unit 91 in advance, or installed in the storage unit 91 via a transmission medium such as the Internet or from a recording medium such as a DVD (Digital Versatile Disk). Can do.

  Next, an electric stage control process for controlling the movement of the electric stage 34 in the XY directions performed by the CPU 93 of FIG. 3 will be described with reference to the flowcharts of FIGS. 4 and 5.

  FIG. 4 is a flowchart for explaining the electric stage control process performed by the CPU 93 of FIG. 3 when paying attention to the speed mode.

  In step S31, the CPU 93 determines whether the current speed mode is the XY speed variable mode or the XY speed fixed mode.

  If it is determined in step S31 that the speed mode is the XY speed variable mode, that is, if the XY speed fixed mode setting button 53 is in the OFF state, the process proceeds to step S32, and the X-axis drive motor By controlling the motor 31 and the Y-axis drive motor 32, the electric stage 34 is moved at a speed according to the XY speed variable mode, that is, at a speed according to the tilt angle of the joystick 51, and the process proceeds to step S33. Proceed to

  In step S33, the CPU 93 determines whether or not the XY speed fixing mode setting button 53 has been turned on.

  If it is determined in step S33 that the XY speed fixing mode setting button 53 has been turned on, the process proceeds to step S34, and the CPU 93 changes the speed mode from the current XY speed variable mode to the XY speed fixing. After setting (changing) the mode, the process returns to step S31, and thereafter the same process is repeated.

  If it is determined in step S33 that the XY speed fixed mode setting button 53 has not been turned on (is still in the off state), the process proceeds to step S35, and the CPU 93 performs three-stage XY speed. It is determined whether or not the switch dial 55 has been rotated.

  If it is determined in step S35 that the three-stage XY speed switching dial 55 has been rotated, the process proceeds to step S36, and the CPU 93 switches the speed from the current speed to the speed of the next stage. The process returns to step S31.

  On the other hand, if it is determined in step S31 that the speed mode is the XY speed fixed mode, that is, if the XY speed fixed mode setting button 53 is on, the process proceeds to step S37 and the CPU 93 Controls the X-axis drive motor 31 and the Y-axis drive motor 32 to move the electric stage 34 at a constant speed according to the XY speed fixed mode, and the process proceeds to step S38.

  That is, in the XY speed fixed mode, no matter how the observer tilts the joystick 51, the electric stage 34 is moved at the speed when the XY speed fixed mode setting button 53 is turned on. The electric stage 34 continues to move.

  However, in the XY speed fixed mode, when the joystick 51 returns to the neutral position, the CPU 93 controls the X-axis drive motor 31 and the Y-axis drive motor 32 so that the movement of the electric stage 34 is stopped. Can do.

  In this case, when the observer tilts the joystick 51 from the neutral position, the electric stage 34 moves when the XY speed fixing mode setting button 53 is turned on regardless of the tilt angle. When the joystick 51 is moved and released from the joystick 51, the joystick 51 returns to the neutral position, and the electric stage 34 stops.

  In step S38, the CPU 93 determines whether or not the XY speed fixed mode setting button 53 has been turned off.

  If it is determined in step S38 that the XY speed fixed mode setting button 53 has been turned off, the process proceeds to step S39, and the CPU 93 changes the speed mode from the current XY speed fixed mode to the XY speed. The variable mode is set, and the process returns to step S31.

  If it is determined in step S38 that the XY speed fixing mode setting button 53 has not been turned off, the process skips step S39 and returns to step S31.

  Here, in order to simplify the explanation, it is assumed that the three-stage XY speed switching dial 55 cannot switch the speed when the speed mode is the XY speed fixed mode. Naturally, the lighting position of the three-stage XY speed display section 59 is not changed.

  As described above, in the electric stage control process of FIG. 4, only by operating the XY speed fixing mode setting button 53, the speed mode is changed to the XY speed fixing mode every time the XY speed fixing mode setting button 53 is operated. And the XY speed variable mode are alternately switched to fix the moving speed of the electric stage 34 to the moving speed of the electric stage 34 when the XY speed fixing mode setting button 53 is turned on, and the joystick Since the speed according to the inclination angle of 51 can be easily switched, the operability of the joystick controller 12 can be improved.

  In the XY speed fixed mode, as in the XY speed variable mode, the electric stage 34 stops when the observer releases the joystick 51 and completes the operation of the joystick 51. For example, the return prohibition switch is in the ON state. In this case, the electric stage 34 can be stopped more easily as compared with the above-mentioned Prior joystick controller in which the electric stage does not stop even if the observer releases his / her hand.

  Furthermore, in the XY speed fixed mode, the electric stage 34 can be moved at the same constant speed as before the stop by simply tilting the joystick 51 after the observer releases the joystick 51 and the electric stage 34 stops. Since the movement is started at the movement speed of the electric stage 34 when the XY speed fixing mode setting button 53 is turned on, the operability of the joystick controller 12 can be further improved.

  Next, FIG. 5 is a flowchart for explaining the electric stage control process performed by the CPU 93 of FIG. 3 when attention is paid to the direction mode.

  In step S71, the CPU 93 determines whether the current direction mode is the XY direction variable mode or the XY direction fixed mode.

  If it is determined in step S71 that the direction mode is the XY direction variable mode, that is, if the XY direction fixed mode setting button 54 is in the OFF state, the process proceeds to step S72, and the CPU 93 executes the X-axis drive motor. By controlling the motor 31 and the Y-axis drive motor 32, the electric stage 34 is moved in the direction corresponding to the XY direction variable mode, that is, the direction corresponding to the tilt direction of the joystick 51, and the process proceeds to step S73.

  In step S73, the CPU 93 determines whether or not the XY direction fixed mode setting button 54 has been turned on.

  If it is determined in step S73 that the XY direction fixed mode setting button 54 has been turned on, the process proceeds to step S74, and the CPU 93 sets the direction mode from the current XY direction variable mode to the XY direction fixed mode. Then, the process returns to step S71, and thereafter the same process is repeated.

  If it is determined in step S73 that the XY direction fixed mode setting button 54 is not turned on, step S74 is skipped and the process returns to step S71.

  On the other hand, if it is determined in step S71 that the direction mode is the XY direction fixed mode, that is, if the XY direction fixed mode setting button 54 is on, the process proceeds to step S75, and the CPU 93 By controlling the shaft drive motor 31 and the Y-axis drive motor 32, the electric stage 34 is moved in a direction corresponding to the XY direction fixed mode, and the process proceeds to step S76.

  In other words, in the XY direction fixed mode, no matter how the observer tilts the joystick 51, the electric stage 34 remains moving in the direction in which the XY direction fixed mode setting button 54 is turned on. The electric stage 34 continues to move.

  However, in the XY direction fixed mode, when the joystick 51 returns to the neutral position, the CPU 93 can control the X-axis drive motor 31 and the Y-axis drive motor 32 so that the movement of the electric stage 34 stops. it can.

  In this case, when the observer tilts the joystick 51 from the neutral position, the electric stage 34 moves when the XY direction fixed mode setting button 54 is turned on regardless of the tilt direction. When the joystick 51 is released from the joystick 51, the joystick 51 returns to the neutral position, and the electric stage 34 stops.

  In step S76, the CPU 93 determines whether or not the XY direction fixed mode setting button 54 has been turned off.

  If it is determined in step S76 that the XY direction fixed mode setting button 54 has been turned off, the process proceeds to step S77, and the CPU 93 sets the direction mode from the current XY direction fixed mode to the XY direction variable mode. Then, the process returns to step S71.

  If it is determined in step S76 that the XY direction fixed mode setting button 54 is not turned off, step S77 is skipped, and the process returns to step S71.

  As described above, in the electric stage control process of FIG. 5, simply by operating the XY direction fixed mode setting button 54, the direction mode is alternately switched between the XY direction fixed mode and the XY direction variable mode, The movement direction can be easily switched between fixing the movement direction of the electric stage 34 when the XY direction fixing mode setting button 54 is turned on and setting the movement direction to a direction according to the tilt direction of the joystick 51. Therefore, the operability of the joystick controller 12 can be improved.

  Further, in the XY direction fixed mode, as in the XY direction variable mode, the electric stage 34 stops when the observer finishes the operation of the joystick 51. For example, when the return prohibition switch is in the on state, The electric stage 34 can be more easily stopped as compared with the above-mentioned Prior joystick controller in which the electric stage does not stop even when released.

  Further, in the XY direction fixed mode, the electric stage 34 can be moved in the same fixed direction (XY direction) as before the stop by simply tilting the joystick 51 after the observer releases the joystick 51 and the electric stage 34 stops. Since the movement is started in the movement direction of the electric stage 34 when the fixed mode setting button 54 is turned on, the operability of the joystick controller 12 can be further improved.

  In the above embodiment, the joystick controller 12 has the two setting buttons, the XY speed fixing mode setting button 53 and the XY direction fixing mode setting button 54, but the XY speed fixing mode setting button 53 and the XY. Instead of the direction fixing mode setting button 54, one setting button having both functions of the XY speed fixing mode setting button 53 and the XY direction fixing mode setting button 54 can be adopted.

  In this case, in addition to switching both the speed mode and the direction mode according to the operation of one setting button, for example, when one setting button is pressed once within a predetermined time, the speed mode is set to the XY speed. When the variable mode is set to the XY speed fixed mode, or from the XY speed fixed mode to the XY speed variable mode, and one setting button is pressed twice within a predetermined time, the direction mode is changed from the XY direction variable mode. The XY direction fixed mode or the XY direction fixed mode can be set to the XY direction variable mode.

  For example, when one setting button is continuously pressed for a predetermined time or more, the speed mode is changed from the XY speed variable mode to the XY speed fixed mode, or from the XY speed fixed mode to the XY speed variable mode. When one setting button is pressed for less than a predetermined time, the direction mode may be set from the XY direction variable mode to the XY direction fixed mode, or from the XY direction fixed mode to the XY direction variable mode.

  Furthermore, in the above-described embodiment, the joystick 51 and the XY speed fixing mode setting button 53 are configured separately, but the joystick 51 and the XY speed fixing mode setting button 53 are configured integrally. That is, for example, the joystick 51 can be operated to be pressed in the direction inside the housing of the joystick controller 12, and the operation of pressing the joystick 51 is the same as the operation of the XY speed fixing mode setting button 53. It can be handled in the same way.

  In this case, the observer can set the XY speed fixed mode only with the hand that operates the joystick 51, so that compared with the case where the joystick 51 and the XY speed fixed mode setting button 53 are configured separately. Thus, the operability of the joystick controller 12 can be improved. Further, the combination of the joystick 51 and the XY direction fixed mode setting button 54 and the combination of the joystick 51 with the XY speed fixed mode setting button 53 and the XY direction fixed mode setting button 54 may be configured integrally. Good.

  In the above embodiment, the joystick controller 12 that controls the electric stage 34 of the microscope 11 has been described. However, the technique of the joystick controller 12 is not limited to this, and for example, an electric pan head that supports a camera. It can also be applied to a controller for controlling the above. That is, the technology of the joystick controller 12 can be applied to any controller as long as it is a controller that controls a motor to move an object such as an electric stage or an electric pan head.

  Further, in the present specification, the processes according to the flowcharts shown in FIGS. 4 and 5 do not necessarily have to be performed in time series in the described order, and may be performed in parallel or individually.

  Furthermore, in this specification, the system represents the entire apparatus constituted by a plurality of apparatuses.

  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.
