Description

  The present invention relates to a controller for an electric drive device and an optical device having the controller.

In recent years, for example, optical devices such as a microscope and a measurement device having an electric drive device that is electrically driven such as a revolver, an XY stage, and a focusing mechanism have been proposed. In some cases, a controller for the observer to control these electric drive devices is wired outside the optical device (see, for example, Patent Document 1).
JP 2007-58066 A

  In the conventional controller, the knob and switch for operating the electric drive unit are determined by the operation direction of the knob and switch and the operation direction of the electric drive unit. Therefore, the controller and right switch are operated with the controller facing to the right. There is a problem that the direction of operating the knob or switch is different between the case where the operation is performed and the case where the operation is performed with the left hand in the left direction.

  For example, when the controller is set up to the right (installed on the right side of the main unit) and the knob is set to move upward with the electric focusing device by rotating the knob from the front to the back with the right hand When the controller is installed to stand leftward (installed on the left side of the main body), the same driving operation is rotated with the left hand from the back toward the front. On the other hand, the manual focusing handle of the main body is executed by rotating the focusing handle from the front to the back, for example, when moving the stage upward, whether it is the right hand or the left hand. Therefore, with the left hand, the operational feeling of the user differs due to the difference in the direction of rotation of the manual focusing handle and the knob of the controller.

  In order to solve the above-described problems, the present invention is detachable from a housing on which an electric drive device is mounted, controls the drive of the electric drive device, and outputs a polarity of a drive signal to the electric drive device output from the controller There is provided a controller having at least one polarity reversing switch for reversing.

  The present invention also provides an optical device having an electric drive device, the electric drive device being controlled by the controller.

  According to the present invention, a controller capable of setting the operational feeling for the electric drive device to be the same when the controller knob or switch is operated rightward and when the controller is operated leftward, and an optical device having the controller Can be provided.

  Hereinafter, a controller according to an embodiment of the present invention and a microscope having the controller will be described with reference to the drawings. The following embodiments are merely for facilitating understanding of the invention, and excluding additions and substitutions that can be performed by those skilled in the art without departing from the technical idea of the present invention. It is not intended.

FIG. 2 shows an example of a stereomicroscope to which a controller is connected, where (a) shows a front view and (b) shows a right side view. FIG. 3 shows a state where the controller is installed on the right side of the stereomicroscope, where (a) shows a front view and (b) shows a right side view. FIG. 4 shows a state where the controller is installed on the left side of the stereomicroscope, where (a) shows a front view and (b) shows a left side view. FIGS. 5A and 5B show a state where the controller is removed from the stereomicroscope, and FIG. 5A shows a front view and FIG. 5B shows a right side view.

  1 and 2, the controller 10 moves the electric vertical movement device 22 in the vertical movement direction for focusing and the zoom control dial 11 that drives the electric zoom optical system 20 of the stereomicroscope (hereinafter referred to as a microscope) 200. A focusing control dial 12 to be driven is disposed in the box 13. The box 13 and the microscope 200 are connected via the wiring 14. The wiring 14 is configured to be detachable from the microscope 200 by a connector 27.

  In the microscope 200, a lens barrel 23 is attached to an upper portion of a mirror body 21 in which a pair of left and right electric zoom optical systems 20 and 20 are incorporated, and a pair of left and right eyepieces 24 and 24 are attached to the lens barrel 23. An objective lens 25 is attached to the lower part of 21. The mirror body 21 is attached to a support column 26 which is a part of the housing of the microscope 200 via an electric vertical movement device 22, and the support column 26 is attached to a base 32 on which the specimen 30 is placed.

  Protrusions 34 and 35 for operating a polarity reversing switch for changing the rotation direction (polarity) of each of the dials 11 and 12 of the controller 10 when the controller 10 is attached to the support 2b are arranged on the left and right below the support 26, respectively. Has been.

  The microscope 200 according to the present embodiment includes a pair of left and right eyepiece optical systems in the lens barrel 23 and includes a pair of left and right electric zoom optical systems 20 and 20, and the objective lens 25 is common to the left and right optical systems. This is the configuration used for

  As shown in FIG. 1B, on the back surface of the controller 10, polarity reversing switches 15, 16 for inverting the polarity of signals output from the controller 10 to the electric zoom optical systems 20, 20 and the electric vertical movement device 22. Is provided. The polarity is the direction of rotation when the member provided in the controller 10 that emits the drive signal is a rotating member, the direction in which the stick inclines in the case of a joystick, or the seesaw type member. One and the other direction. Polarity reversal means that, for example, when a member that emits a drive signal is a rotating member, if a signal A is generated by a right rotation, the signal A is switched to generate a signal A by a left rotation.

  As shown in FIG. 3, the polarity reversing switch 15 is pressed by the protrusion 34 that is the polarity reversing switch operating portion when the box 10 is attached to the lower right portion of the support column 21, whereby each dial 11, 12 of the box 10 is pressed. Is set to output a signal in a state in which is placed rightward. In this state, a right-handed operation state is set in which the user operates the dials 11 and 12 with the right hand. By making the width of the box 10 and the width of the support column 21 substantially the same, it becomes possible to fit without worrying about the lateral position of the polarity reversing switch 15 and the protrusion 34.

  The rotation operation of each dial 11 and 12 and each driving state in this state will be described with reference to FIG.

  As shown in FIG. 3, in the right-handed operation state, when the zoom control dial 11 is rotated from the front to the back (clockwise in FIG. 1) with the right hand, the magnifications of the electric zoom optical systems 20 and 20 are increased. Is set so that the magnification of the electric zoom optical systems 20 and 20 decreases when the zoom lens is rotated in the forward direction (counterclockwise in FIG. 1). When the focusing control dial 12 is rotated from the front to the back (clockwise in FIG. 1), the electric vertical movement device 22 moves downward, and from the back to the front (counterclockwise in FIG. 1). When rotated, the electric vertical movement device 22 moves upward, and the specimen 30 is focused on the front side of the objective lens 25. Accordingly, the user can observe the image of the specimen 30 through the eyepiece lens 24.

  Thus, by attaching the box 13 to the position of the projection 34 on the right side of the column 21, the projection 34 pushes the polarity reversing switch 15, and the dials 11 and 12 are set to the right-handed operating state. The box 13 is attached to and fixed to the support column 21 by a mechanism (not shown) (for example, a click mechanism or a magnet).

  Next, the case of the left-handed operation state will be described with reference to FIG.

  As shown in FIG. 4, when the box 10 is attached to the lower left part of the column 21, the polarity reversing switch 16 is pushed by the projection 35 which is a polarity reversing switch, so that the dials 11 and 12 of the box 10 face leftward. Is set to output a signal in a state of being arranged in In this state, a left-handed operating state is set in which the user operates the dials 11 and 12 with the left hand.

  The rotation operation of each dial 11 and 12 and each driving situation in this state will be described.

  As shown in FIG. 4, when the zoom control dial 11 is rotated from the front to the back (counterclockwise direction in FIG. 1) in the left-handed state, the magnification of the electric zoom optical systems 20 and 20 is increased, and from the back to the front The zoom is set so that the magnification of the electric zoom optical systems 20 and 20 is lowered when rotated in the direction (clockwise in FIG. 1). Further, when the focusing control dial 12 rotates from the front to the back (counterclockwise in FIG. 1), the electric vertical movement device 22 moves downward, and from the back to the front (clockwise in FIG. 1). When rotated, the electric vertical movement device 22 moves upward, and the specimen 30 is focused on the front side of the objective lens 25. Accordingly, the user can observe the image of the specimen 30 through the eyepiece lens 24.

  Thus, by attaching the box 13 to the left protrusion 35 of the support column 21, the protrusion 35 pushes the polarity reversing switch 16, and the dials 11 and 12 are set to the left-handed operating state. Note that the box 10 is attached to and fixed to the column 21 by a mechanism (not shown) similar to the right side (for example, a click mechanism or a magnet).

  As described above, the controller 10 according to the embodiment operates by pushing the polarity reversing switches 15 and 16 with the protrusions 34 and 35 according to the left and right mounting positions of the microscope 200, thereby operating the right-handed system. The left-handed operating state is set. As a result, the operation state when operating with the left and right hands can be set to the same state. By setting in this way, for example, the operation ring of the mechanical zoom optical system, the rotation direction of the mechanical focusing handle and the rotation direction of the dials 11 and 12 on the controller are operated with the right hand or the left hand. Regardless of the case, it is possible to make them coincide with each other, and it is possible to prevent an erroneous operation due to a change in the operating hand and to improve the operational feeling.

  In the embodiment described above, the right-handed and left-handed operating states (for example, the rotation direction of the dial) are switched by the two polarity reversing switches 15 and 16 and the two protrusions 34 and 35. When the state is set to the initial state (default), one polarity reversing switch is provided on the controller, one protrusion is provided on the lower left side of the support column 21, and when the controller is disposed on the left side, the protrusion operates the polarity reversing switch. You may comprise so that it may set to an operation state. When the controller is not installed on the left side, the polarity reversing switch is set to the initial state (default). Note that the same effect can be obtained even if the polarity reversing switch and the protrusion are configured by switching the right and left in one description. The polarity reversing switches 15 and 16 are not limited to the mechanical operation described above, and may be configured to perform a polarity reversing operation using various sensors such as a Hall element. By using a Hall element or the like, it is possible to prevent malfunction due to poor contact or the like.

  FIG. 5 shows a state in which the controller 10 is removed from the microscope 200 and used. In this case, since the above-described polarity reversing switches 15 and 16 do not operate, the signal polarity cannot be switched when the controller 10 is placed rightward or leftward.

  Therefore, the controller 10 according to the embodiment is further provided with a manual polarity reversing switch 17. As a result, the controller 10 can be set to a state in which the same operational feeling as described above can be obtained even at a position away from the microscope 200, and the setting according to the user's preference is possible without being limited thereto. By providing the manual polarity reversing switch 17 in this way, the controller 10 can be used in a preferred posture at a position away from the microscope 200.

  The controller 10 described above is connected to the microscope 200 by wire. However, the controller has a built-in transmission / reception unit for transmitting and receiving wireless and infrared rays with a battery, and the microscope 200 side also has a transmission and reception unit for transmitting and receiving wireless and infrared rays. It may be built in and configured to transmit / receive signals to / from the microscope 200 by radio or infrared. This eliminates the need to take care of wiring.

  In the case of a controller that transmits and receives signals by radio or infrared, a power supply terminal that supplies power from the microscope 200 to the controller is disposed at a position where the controller of the microscope 200 is attached, and a terminal that is joined to the power supply terminal on the controller. By further providing the unit, the battery of the n controller 10 can be charged with electric power while the controller is attached to the microscope 200.

  In the above-described embodiment, the case where the controller 10 has the zoom control dial 11 and the focusing control dial 12 has been described. However, the present invention is not limited to this, and various dials and switches corresponding to other electric drive devices are provided. It may be arranged. Whether the polarity of any dial or switch is reversed by the polarity reversal switch may be appropriately determined at the time of design. That is, the switches that do not change the operation direction and the operation direction in the right direction and the left direction do not invert the output polarity, and only the switches in which the operation direction changes may be designed to invert the output polarity.

  In the above embodiment, the stereomicroscope has been described as a representative, but it goes without saying that the present invention can be applied to various apparatuses and controllers equipped with an electric drive device such as other microscopes and measuring devices.

The controller concerning an embodiment is shown, (a) shows a front view and (b) shows a back perspective view, respectively. An example of the stereomicroscope to which a controller is connected is shown, (a) shows a front view and (b) shows a right side view, respectively.
