[Control system]
FIG. 8 shows an example of a configuration example of the control system of the ophthalmologic apparatus 1. 8, parts similar to those in FIGS. 1A to 7B are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The control system of the ophthalmologic apparatus 1 is configured around the control unit 200. The control unit 200 includes, for example, a microprocessor, a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk drive, and the like. The control unit 200 is provided with a main control unit 201 and a storage unit 202.

  The main control unit 201 controls each unit of the ophthalmologic apparatus 1. In particular, the main control unit 201 controls the measurement head 3, the drive unit 8, the UI unit 10, and the operation unit 40. Examples of the control for the measurement head 3 include measurement of characteristics of the eye to be examined or control of an optical system for photographing the eye to be examined. Examples of the control for the drive unit 8 include a drive control for a vertical drive motor, a left / right drive motor, and a front / rear drive motor. Examples of the control on the UI unit 10 include display control of an image of an eye to be examined and an operation screen acquired using the measurement head 3, and acceptance control of a touch operation on the UI unit 10. Examples of the control for the operation unit 40 include an operation reception control for the operation unit 40. The main control unit 201 can control each unit of the ophthalmologic apparatus 1 based on the operation content performed on the UI unit 10 or the operation unit 40.

  The UI unit 10 detects a touch operation on the display screen 10a. An operation detection signal corresponding to the touch operation detected by the UI unit 10 is transmitted to the main control unit 201.

  As described above, the operation unit 40 includes the up / down / left / right operation unit 10b and the front / rear operation unit 10c. The operation unit 40 detects an operation for designating an up / down / left / right direction with respect to the up / down / left / right operation unit 10b. An operation detection signal corresponding to the designated operation in the vertical and horizontal directions detected by the operation unit 40 is transmitted to the main control unit 201. The operation unit 40 detects an operation for designating the front-rear direction with respect to the front-rear operation unit 10 c. An operation detection signal corresponding to the designation operation in the front-rear direction detected by the operation unit 40 is transmitted to the main control unit 201.

  The sensor 32 detects the direction of the display screen 10a. As described above, the sensor 32 detects the orientation of the display screen 10a of the UI unit 10 by detecting the rotation of the UI unit 10 about the horizontal axis O2.

  Based on the detection result obtained by the sensor 32, the main control unit 201 can invert the image information displayed on the UI unit 10 vertically and horizontally. As a result, the UI unit 10 is rotated about the horizontal axis O2, and the display screen 10a is turned upside down and when it is turned upside down, the visual position of the image of the eye to be examined and the operation button is the same. Various information can be displayed on the display screen 10a so as to be positioned.

  The main control unit 201 can change the control content based on the operation detection signal from the UI unit 10 based on the detection result obtained by the sensor 32. For example, the main control unit 201 inverts the image information displayed on the display screen 10a up and down and left and right in accordance with the detection result obtained by the sensor 32, and a new operation area corresponding to the image information after the up and down and left and right inversion. Is set in the display screen 10a.

  The main control unit 201 can change the control content based on the operation detection signal from the operation unit 40 based on the detection result obtained by the sensor 32. For example, the main control unit 201 reverses the operation direction specified by the signal from the up / down / left / right operation unit 10b according to the detection result obtained by the sensor 32, and specifies by the signal from the front / rear operation unit 10c. Reverse the operation direction to be performed. The main control unit 201 can change the control content based on the operation detection signal from the operation unit 40 based on the detection result obtained by the sensor 32 by referring to the control information stored in the storage unit 202 in advance. Is possible.

  FIG. 9 shows an example of control information according to the embodiment. The control information shown in FIG. 9 is stored in advance in the storage unit 202. For example, when the detection signal acquired by the sensor 32 is on (the UI unit 10 is in a horizontal state), the main control unit 201 changes the direction specified by the operation detection signal from the up / down / left / right operation unit 10b or the front / rear operation unit 10c. The operation direction is specified as it is. When the detection signal is off (the UI unit 10 has exceeded a predetermined angle from the horizontal state), the main control unit 201 is in the direction specified by the operation detection signal from the up / down / left / right operation unit 10b or the front / rear operation unit 10c. Is changed based on the control information, and the changed direction is specified as the operation direction.

  Thereby, the ophthalmologic apparatus 1 can change the control content based on the signal from the UI unit 10 according to the relative position of the subunit 30 with respect to the main unit 20 detected by the detection unit. The ophthalmologic apparatus 1 changes the control content based on signals from the operation units (up / down / left / right operation unit 10b, front / rear operation unit 10c) according to the relative position of the subunit 30 with respect to the main unit 20 detected by the detection unit. Is possible.

  The main control unit 201 controls each unit of the ophthalmologic apparatus 1 based on the operation content for the UI unit 10 or the operation unit 40.

  When it is determined that the specified operation direction is the front-rear direction, the main control unit 201 controls the front-rear drive motor. Thereby, the measuring head 3 is moved in the front-rear direction. When it is determined that the specified operation direction is the left-right direction, the main control unit 201 controls the left-right drive motor. Thereby, the measuring head 3 is moved in the left-right direction. When it is determined that the specified operation direction is the vertical direction, the main control unit 201 controls the vertical drive motor. Thereby, the measuring head 3 is moved in the vertical direction.

  Further, the main control unit 201 starts measurement by the measurement head 3 based on an operation detection signal corresponding to the detection result of the touch operation on the UI unit 10. Thereby, measurement is performed in a sequence corresponding to the currently set measurement mode.

  The main control unit 201 can sequentially switch a plurality of measurement modes in a predetermined order based on an operation detection signal corresponding to an operation on the UI unit 10 or the operation unit 40. In this embodiment, the measurement mode includes a REF / KRT measurement mode and a TONO / PACHO measurement mode. Each time a measurement mode switching operation is detected, one of the REF / KRT measurement mode and the TONO / PACHO measurement mode is alternately switched. In the REF / KRT measurement mode, it is possible to perform measurement in any one of a ref measurement mode, a kerato measurement mode, and a ref / kera measurement mode. The reflex measurement mode is a mode for measuring in the spherical refractive power, cylindrical refractive power, and astigmatic axis direction. The kerato measurement mode is a mode for measuring the corneal curvature radius, the corneal astigmatic axis direction, and the corneal refractive power. The ref / kera measurement mode is a mode in which ref measurement and kerato measurement are continuously performed. In the TONO / PACHO measurement mode, it is possible to further measure in either the TONO measurement mode or the PACHO measurement mode. The TONO measurement mode is a mode for measuring intraocular pressure. The PACHO measurement mode is a mode for measuring intraocular pressure and corneal thickness.

  The main control unit 201 can move the measurement head 3 to the examination position for the right eye or the left eye based on an operation detection signal corresponding to an operation on the UI unit 10 or the operation unit 40. In this embodiment, every time a switching operation of the eye to be examined is detected, the measuring head 3 is alternately moved to either the predetermined inspection position for the right eye or the predetermined inspection position for the left eye.

  Further, the main control unit 201 performs processing for writing data into the storage unit 202 and processing for reading data from the storage unit 202.

  The storage unit 202 stores various data including control information shown in FIG. Examples of data stored in the storage unit 202 include image data of an eye to be examined, eye information to be examined, and the like. The eye information includes information about the subject such as patient ID and name, and information about the eye such as left / right eye identification information. The storage unit 202 stores various programs and data for operating the ophthalmologic apparatus 1.

  The data processing unit 210 generates measurement values in the REF / KRT measurement mode and the TONO / PACHO measurement mode by analyzing an image such as an image of the eye to be examined obtained by controlling the observation / imaging optical system 6. Is possible.

  As shown in FIG. 8, the main control unit 201 includes an alignment control unit 201a. The alignment control unit 201a controls the alignment means provided in the measurement head 3, thereby aligning the optical system with respect to the eye to be examined. For example, the measuring head 3 includes, as alignment means, a Z alignment projection system for performing alignment in the Z direction and an XY alignment spot projection system for performing alignment in the XY direction.

  The Z alignment projection system includes, for example, a light source and a detection element. The light source projects light onto the cornea of the eye to be examined. The detection element detects the return light of the light projected on the cornea by the light source. When the position of the corneal apex moves in the Z direction, the position of the return light projected on the detection element changes. When automatically performing alignment in the Z direction, the alignment control unit 201a obtains the position of the corneal apex of the eye to be examined with respect to the objective lens by analyzing a change in the position of the return light detected on the detection element, for example. The measuring head 3 is moved in the Z direction based on the determined position.

  The XY alignment spot projection system includes, for example, a light source. The optical path of light from the light source is combined with the optical path of the observation / photographing optical system 6. The light from the light source is projected onto the cornea of the eye to be examined, for example, via the optical path of the observation / imaging optical system 6. The light projected onto the eye to be examined is reflected by the cornea and projected onto an image sensor provided separately for photographing. When the alignment in the X and Y directions is automatically performed, the alignment control unit 201a moves the measurement head 3 to X so that a deviation amount between a predetermined alignment target position and the position of the return light projected on the image sensor is canceled, for example. Move in at least one of the direction and the Y direction.

  In this embodiment, according to the direction of the display screen 10a, it can align manually as follows.

(When the detection signal from the sensor is on)
When the UI unit 10 is arranged with respect to the main unit 20 as shown in FIGS. 1A, 1B, 4A, and 4B, for example, the detection signal from the sensor 32 is turned on. At this time, the direction designated by the operation detection signals from the up / down / left / right operation unit 10b and the front / rear operation unit 10c is directly specified as the operation direction. Therefore, the alignment control unit 201a moves the measuring head 3 in the direction specified by the operation detection signals from the up / down / left / right operation unit 10b and the front / rear operation unit 10c. Thereby, the examiner can perform alignment manually as usual.

(When the detection signal from the sensor is off)
When the UI unit 10 is arranged with respect to the main unit 20 as shown in FIGS. 2A, 2B, 3A, and 3B, for example, the detection signal from the sensor 32 is turned off. At this time, the direction designated by the operation detection signals from the up / down / left / right operation unit 10b and the front / rear operation unit 10c is changed based on the control information shown in FIG. Therefore, the alignment control unit 201a moves the measurement head 3 in the operation direction changed based on the control information. Thereby, even when the UI unit 10 is arranged as shown in FIGS. 2A, 2B, 3A, and 3B with respect to the main body unit 20, the operability with respect to the ophthalmologic apparatus 1 is not deteriorated. The examiner can manually perform the alignment as usual.

  The up / down / left / right operation unit 10b is an example of the “first operation unit” according to the embodiment. The front-rear operation unit 10c is an example of a “second operation unit” according to the embodiment. The sensor 32 is an example of a “detection unit” according to the embodiment.

[effect]
The effect of the ophthalmologic apparatus according to the embodiment will be described.

  The ophthalmologic apparatus (for example, ophthalmologic apparatus 1) according to the embodiment includes a main body unit (for example, main body unit 20), a subunit (for example, subunit 30), an operation unit (for example, operation unit 40), and a control unit. (For example, the control unit 200). The main body unit houses an optical system (for example, an observation / imaging optical system 6) for optically inspecting the eye to be examined. The sub-unit is movable relative to the main unit, and a user interface unit (for example, UI unit 10) is provided. The operation unit is provided in the vicinity of the user interface unit. The control unit performs control based on signals (for example, operation detection signals) from the user interface unit and the operation unit.

  According to such a configuration, the main unit and the subunit provided with the user interface unit are integrated, and the subunit can be moved relative to the main unit, so that the examiner can move the user to any position. An interface part can be arranged. Further, since the operation unit is provided separately from the user interface unit and in the vicinity thereof, the examiner can arrange the user interface unit at an arbitrary position without causing a decrease in operability. The operation can be performed.

  In the ophthalmologic apparatus according to the embodiment, the user interface unit is provided on the first surface (for example, the front surface) of the subunit, and the operation unit is the second surface (for example, the back surface) of the subunit different from the first surface. A second operation unit (for example, the front / rear operation unit 10c) provided in the front and rear may be included.

  According to such a configuration, since both the user interface unit and the second operation unit can be provided in the subunit, it is possible to reduce the size of the subunit so that the relative movement described above is not hindered. .

  The ophthalmologic apparatus according to the embodiment may include a detection unit (for example, sensor 32). The detection unit detects the relative position of the subunit with respect to the main unit. A control part changes the control content based on the signal from an operation part according to the relative position detected by the detection part.

  According to such a configuration, since the control content based on the signal from the operation unit is changed according to the relative position of the subunit with respect to the main unit, the examiner has arranged the user interface unit at an arbitrary position. Even in this case, it is possible to perform operations on the ophthalmologic apparatus without deteriorating operability.

[Modification]
The configuration of the ophthalmologic apparatus according to the embodiment is not limited to the configuration described in the above embodiment. The ophthalmologic apparatus according to the embodiment may be configured as follows, for example.

(First modification)
In the above-described embodiment, the positional relationship of the up / down / left / right operation unit 10b with respect to the display screen 10a varies depending on the position of the UI unit 10. Therefore, depending on the position of the UI unit 10, the examiner needs to operate the up / down / left / right operation unit 10b with the right hand or the left hand. On the other hand, in the first modification of the embodiment, since the subunit 30 is configured to be rotatable as follows, the examiner moves the up / down / left / right operation unit 10b to the right hand (regardless of the position of the UI unit 10). It becomes possible to operate only with the left hand).

  The configuration and operation of the ophthalmologic apparatus according to the first modification are substantially the same as the configuration and operation of the ophthalmologic apparatus 1 according to the embodiment. Below, the ophthalmologic apparatus which concerns on a 1st modification is demonstrated centering around difference with this embodiment.

  In FIG. 10, the perspective view of schematic structure of the subunit which concerns on the 1st modification of embodiment is typically shown. 10, parts that are the same as those in FIG. 6 are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

  The configuration of the subunit 30 ′ according to the first modification is different from the configuration of the subunit 30 according to the embodiment in that the subunit 30 ′ passes through the display screen 10a and the axis O3 orthogonal to the display screen 10a. It is a point which can be rotated to the center.

  For example, the subunit 30 ′ according to the first modification is provided on the front side member 50. The display screen 10 a and the up / down / left / right operation unit 10 b are provided on the surface of the front side member 50. The front / rear operation unit 10 c is provided in the vicinity of the left end or the right end of the back surface of the front side member 50. The mounting bracket plate portion 13g is fixed to the back surface of the rear surface side member 51 by a fixing member such as a screw. The front side member 50 is held so as to be rotatable about the axis O <b> 3 on the surface side of the rear side member 51. For example, the rear side member 51 is provided with a rotation mechanism 52 having a known configuration on the axis O3. The rotation mechanism 52 rotates the front side member 50 about the axis O3 with respect to the rear side member 51.

  Cutout portions 53 a and 53 b are formed at the left end portion and the right end portion of the rear surface side member 51. When the rotation angle of the front side member 50 around the axis O3 is a predetermined angle (0 degree or 180 degree in FIG. 10), the front / rear operation unit 10c is exposed on the back side of the subunit 30 ′. Has been. Thereby, when the rotation angle is a predetermined angle, the examiner can operate the front-rear operation unit 10c.

  According to the above configuration, the examiner can manually rotate the display screen 10a around the axis O3, for example, according to the position of the moved subunit 30 ′ (UI unit 10 ′). . Thereby, the positional relationship of the up / down / left / right operation unit 10b with respect to the display screen 10a is maintained, and the situation in which the positional relationship of the up / down / left / right operation unit 10b with respect to the display screen 10a changes depending on the position of the UI unit 10 ′ can be avoided. Therefore, it is not necessary to change the image information in the vertical direction and the horizontal direction according to the orientation of the display screen 10a. Further, it is not necessary to change the direction specified by the operation detection signal in accordance with the direction of the display screen 10a. That is, in the first modification, the sensor 32 can be omitted.

  Alternatively, in addition to the sensor 32, a new sensor for detecting the rotation angle of the front side member 50 around the axis O3 may be provided. In this case, based on the detection signal from the sensor 32 and the detection signal from the new sensor, the image information can be changed in the vertical direction and the horizontal direction according to the orientation of the display screen 10a. Similarly, by referring to the control information set in advance as shown in FIG. 9, it is possible to identify the operation direction from the direction specified by the operation detection signal based on these detection signals.

  The rotation mechanism 52 may rotate the front side member 50 with an electrical mechanism. In this case, an actuator that generates a driving force for rotating the front side member 50 and a transmission mechanism that transmits the driving force are provided. The actuator is constituted by, for example, a pulse motor. The transmission mechanism is constituted by, for example, a combination of gears, a rack and pinion, or the like.

[effect]
Effects of the ophthalmologic apparatus according to the first modification of the embodiment will be described.

  In the ophthalmologic apparatus according to the first modification of the embodiment, the user interface unit includes a display surface (for example, a surface), and is sub-centered about an axis (for example, the axis O3) that passes through the display surface and is orthogonal to the display surface. A rotation mechanism (for example, a rotation mechanism 52) that rotates the unit may be included.

  According to such a configuration, even when the user interface unit is arranged at an arbitrary position, the positional relationship between the examiner and the user interface unit can be maintained, so that an image displayed on the user interface unit There is no need to perform control such as inversion of information. In particular, when an operation unit is provided in the vicinity of the user interface unit, the positional relationship of the operation unit with respect to the user interface unit is also maintained, and deterioration in operability with respect to the ophthalmologic apparatus can be prevented.

(Second modification)
In the above-described embodiment or the first modification, the case where the up / down / left / right operation unit 10b is provided around the display screen 10a has been described. However, the configuration of the ophthalmologic apparatus according to the embodiment is not limited thereto. At least the up / down / left / right operation unit 10 b may be movable relative to the UI unit 10.

  The configuration and operation of the ophthalmologic apparatus according to the second modification are substantially the same as the configuration and operation of the ophthalmic apparatus 1 according to the embodiment. Below, the ophthalmologic apparatus which concerns on a 2nd modification is demonstrated centering around difference with this embodiment.

And a front / rear operation unit 10c. For example, a rotation mechanism that rotatably holds the base end portion of the arm member 61 around the rotation shaft 60 is provided on the back surface of the subunit 30 ″. At the tip of the arm member 61, an up / down / left / right operation unit 10b is provided.

  For example, a sensor that detects the rotation angle of the arm member 61 based on a predetermined rotation angle is provided, and the position of the up / down / left / right operation unit 10b relative to the display screen 10a can be specified based on a detection signal from the sensor. It is. As shown in FIG. 9, by referring to preset control information, the operation direction is specified from the direction specified using the up / down / left / right operation unit 10b according to the specified position of the up / down / left / right operation unit 10b. It is possible.

  Further, the up / down / left / right operation unit 10b may be rotatable about a rotation axis passing through the up / down / left / right operation unit 10b (arrow direction m in FIG. 11). Accordingly, the up / down / left / right operation unit 10b itself can be rotated according to the position of the up / down / left / right operation unit 10b with respect to the display screen 10a, and the up / down / left / right operation unit 10b can be operated at an arbitrary position with respect to the display screen 10a. Is possible. In this case, it may not be necessary to change the direction specified by the operation detection signal in accordance with the direction of the display screen 10a.
