[0003] [Patent Document 1] JP 2017-217121 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, when examining many subjects in a group medical examination or the like, the examiner may deal with subjects who cannot understand the official language. The examiner must confirm the language that the subject can understand, and then change the preset announcement language (official language) to a language that the subject can understand. Furthermore, after finishing the examination of the subject, the examiner must return the temporarily changed announcement language setting to its original state. Such actions by the examiner to confirm the language, change the language setting, and return the language setting to its original state are time-consuming and laborious.

[0005] In consideration of the above problems, the present disclosure has an object to provide an ophthalmic device and an ophthalmic device control program that enable easy setting of an announcement language suitable for a subject. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention is characterized by having the following configuration.

[0010] <Summary> An overview of the ophthalmologic apparatus of this embodiment will be described. The items classified in <> below can be used independently or in conjunction with each other.

[0011] The ophthalmic apparatus of the present embodiment is an apparatus for examining an eye to be examined. For example, the ophthalmic apparatus may be an objective ophthalmic examination apparatus that objectively measures the optical characteristics (ocular refractive power, axial length, corneal shape, etc.) of the eye to be examined. For example, the ophthalmic apparatus may be an ophthalmic imaging apparatus that photographs the anterior part of the eye to be examined and obtains anterior part image data of the eye to be examined, corneal shape data of the eye to be examined, etc. Also, for example, the ophthalmic apparatus may be an ophthalmic imaging apparatus that photographs the fundus of the eye to be examined and obtains frontal fundus image data of the eye to be examined, fundus tomographic image data of the eye to be examined, etc. That is, the ophthalmic apparatus may be at least one of an ocular refractive power measuring apparatus, a corneal curvature measuring apparatus, a corneal shape measuring apparatus, an intraocular pressure measuring apparatus, an axial length measuring apparatus, a fundus camera, an OCT (Optical Coherence Tomography), an SLO (Scanning Laser Ophthalmoscope), etc.

[0012] <Notification means> The ophthalmologic apparatus of the present embodiment may include a notification means. The notification means is a means for announcing to the subject. For example, the notification means may be at least one of a display means (e.g., the display unit 75), a sound generating means (e.g., the announcement output unit 89), and the like.

[0013] <Display control means> The ophthalmologic apparatus of the present embodiment may include a display control means (e.g., the control unit 70). The display control means causes the display means to display a first language setting screen (e.g., a language selection prompting screen 810) for setting a language for announcements, which is different from a condition setting screen for setting examination conditions for the subject's eye.

[0014] The condition setting screen may be a screen on which the examination conditions of the subject's eye can be set. For example, the condition setting screen may be a screen on which at least one of conditions such as input of identification information for identifying the examiner, input of identification information for identifying the subject, and selection of the eye to be measured can be set. For example, the condition setting screen may be a home screen (for example, the home screen 900) before moving to the examination of the subject's eye. For example, the condition setting screen may be an examination screen (for example, the examination screen 800) including at least an observation image of the subject's eye and a call button for calling a second language setting screen for setting the language of the announcement. That is, the condition setting screen may be a screen on which the language of the announcement can be selected by calling the second language setting screen. The second language setting screen will be described later.

[0015] The first language setting screen may be a screen that includes a list of multiple languages ​​and allows an arbitrary language to be selected based on the list. In other words, the first language setting screen may be a screen that allows an announcement language to be selected using the list of languages ​​on the first language setting screen.

[0016] The first language setting screen may further include guidance information for guiding the selection of the announcement language (e.g., an operation explanation screen 811) and setting buttons corresponding to a plurality of languages ​​(e.g., a language selection button 812). For example, the guidance information may be an icon or a pictogram, or may be a message corresponding to each language.

[0017] The second language setting screen may be a screen including a list of a plurality of languages, and allowing an arbitrary language to be selected based on the list. In other words, the second language setting screen may be a screen allowing an announcement language to be selected using the list of languages ​​on the second language setting screen. In this embodiment, the second language setting screen may be provided as a screen different from the first language setting screen, or may be provided as a screen common to the first language setting screen.

[0018] The display control means may cause the display means to display the first language setting screen as an initial screen every time the examination of the subject's eye is completed. In other words, the display means may cause the display means to display the first language setting screen as an initial screen every time the subject's eye is changed. This allows the announcement language suitable for the subject to be easily set every time an examination is performed.

[0019] The display control means may display a condition setting screen or a first language setting screen on the display means according to the mode switched by the mode switching means described later. For example, in the first mode, when the subject cannot understand the language of the announcement, the language can be appropriately changed from a predetermined language set in advance to the language desired by the subject. For example, in the second mode, the language of the announcement can be selected in advance every time the subject changes according to the language used by the subject. Therefore, the mode can be switched according to the test situation of the subject, and the language of the announcement desired by the subject can be easily selected.

[0020] <Mode switching means> The ophthalmologic apparatus of the present embodiment may include a mode switching means (e.g., the control unit 70). The mode switching means switches between a first mode in which a condition setting screen is displayed on the display means as an initial screen every time an examination of a subject's eye is completed, and a second mode in which a first language setting screen is displayed on the display means as an initial screen every time an examination of a subject's eye is completed.

[0021] The first mode may be a mode for the examiner to select the language of the announcement. For example, the first mode may be selected when the examiner proceeds with the examination while talking to the examinee. When the examinee cannot understand the preset language of the announcement, the language of the announcement may be changed. The second mode may be a mode for the examinee to select the language of the announcement. For example, the second mode may be selected when the examinee proceeds with the examination by himself. The examinee may change the language of the announcement that he can understand by himself.

[0022] <Control means> The ophthalmic apparatus of this embodiment may include a control means (e.g., a control unit 70). The control means outputs an announcement from the notifying means in a selected language based on an operation signal from an operation means for selecting a language for the announcement, and proceeds with the examination of the subject's eye. For example, the control means may output an announcement and proceed with the examination based on an operation signal from the operation means operated by the examiner. Also, for example, the control means may output an announcement and proceed with the examination based on an operation signal from the operation means operated by the examinee. The operation means may be a button or the like provided on at least one of the ophthalmic apparatus main body, a controller connected to the ophthalmic apparatus by wired or wireless communication, etc., or may be a button or the like displayed on the display means.

[0023] The control means may output an announcement from the notifying means in the selected language based on an operation signal from a setting button (e.g., language selection button 812) included in the first language setting screen, and proceed with the examination of the subject's eye. The control means may also output an announcement from the notifying means in the selected language based on an operation signal from a setting button included in the second language setting screen, and proceed with the examination of the subject's eye.

[0024] The control means may set the language of the announcement to a preset initial language every time the examination of the subject's eye is completed. For example, the control means may set the language of the announcement to the initial language every time the examination of the subject's eye is completed in the first mode. Also, for example, the control means may set the language of the announcement to the initial language every time the examination of the subject's eye is completed in the second mode. This reduces the examiner's effort to change the announcement language back to the original language that was changed to suit the subject after the examination of the subject's eye is completed. Also, the operation time required to change the announcement language back is reduced.

[0025] When the second mode is set, the control means may change the operation control for prohibiting the operation of the ophthalmic apparatus after the announcement language is selected. For example, the operation control for prohibiting the operation of the ophthalmic apparatus may be control for prohibiting transmission or reception of an operation signal from the operation means. In other words, the input of an operation signal from the operation means may be invalidated. For example, the operation control for prohibiting the operation of the ophthalmic apparatus may be control for outputting a message to the subject that the operation is prohibited. As an example, the message may be notified by the notification means. For example, the operation control for prohibiting the operation of the ophthalmic apparatus may be control for changing the display of the display means. As an example, the condition setting screen may be changed to a different screen, such as blacking out the condition setting screen. For example, the operation control for prohibiting the operation of the ophthalmic apparatus may be control for accepting an input signal from a detection means of the chin rest (for example, the chin rest sensor 3c). In this case, the input signal from the detection means may be invalidated before the announcement language is selected, and the input signal from the detection means may be valid after the announcement language is selected.

[0026] The above-mentioned operation control may be performed by any one of the above controls, or may be performed by combining a plurality of the above controls. For example, this reduces the possibility that the subject may operate the ophthalmic device or change the settings, causing the examination of the subject's eye to be inappropriately performed, and allows the examination of the subject's eye to be appropriately performed.

[0027] The present disclosure is not limited to the device described in the present embodiment. For example, the terminal control software (program) performing the functions of the above embodiment may be supplied to a device or a system via a network or various storage media, and a control device (e.g., a CPU) of the device or the system may read and execute the program.

[0028] <Example> An example of an ophthalmic apparatus according to the present embodiment will be described below. Note that in the following description, an eye refractive power measuring apparatus will be taken as an example of the ophthalmic apparatus.

[0029] <Device configuration> FIG. 1 is an external view of an eye refractive power measuring device 1. The eye refractive power measuring device 1 includes a base 2, a face support unit 3, a drive unit 4, a display unit 75, an operation unit 76, an announcement unit 89, a face photographing unit 90, and a measurement unit 100. The face support unit 3 is fixed to the base 2 and supports the face of the subject. The face support unit 3 includes a forehead rest 3a, a chin rest 3b, a chin rest sensor 3c, and a chin rest drive unit 3d. The forehead rest 3a supports the forehead of the subject. The chin rest 3b supports the chin of the subject. The chin rest sensor 3c detects whether the chin is placed on the chin rest 3b. The chin rest drive unit 3d moves the chin rest 3b up and down to adjust the height. The drive unit 4 drives the measurement unit 100 in the XYZ directions relative to the base 2. The display unit 75 displays various information (e.g., a face image of the subject, an image of the anterior eye of the subject's eye, a measurement result of the subject's eye, etc.). The operation unit 76 performs various settings. In this embodiment, the display unit 75 with a touch panel also serves as the operation unit 76. The operation unit 76 may be various human interfaces such as a touch panel, a joystick, a mouse, a keyboard, a trackball, and a button. The announcement unit 89 makes announcements to the subject or the examiner. In this embodiment, the announcement unit 89 is an audio output unit such as a speaker. Of course, the announcement unit 89 may be a display unit such as a monitor. The face photographing unit 90 photographs, for example, the face of the subject's eye. The face photographing unit 90 photographs, for example, a face including at least one of the left and right eyes of the subject. The measurement unit 100 houses an optical system described later.

[0030] 2 is a schematic diagram of the optical system and control system of the eye refractive power measurement device 1. The measurement unit 100 includes a measurement optical system 200, a fixation target optical system 300, an index projection optical system 400, an observation optical system 500, a face illumination optical system 600, and a face photographing optical system 700. The measurement optical system 200 objectively measures the eye refractive power (e.g., spherical power, cylindrical power, astigmatism axis angle, etc.) of the subject's eye E. The fixation target optical system 300 presents a fixation target to the subject's eye E. The index projection optical system 400 projects an alignment index to the subject's eye E. The observation optical system 500 images the anterior segment of the subject's eye E. The face illumination optical system 600 illuminates the subject's face. The face photographing optical system 700 photographs the subject's face. In addition, a beam splitter 230 is disposed in front of the subject's eye E. The beam splitter 230 guides the measurement light beam from the fixation target optical system 300 to the subject's eye E. The beam splitter 230 also guides the reflected light beam from the anterior segment of the subject's eye E to the observation optical system 500.

[0031] <Measurement optical system> The measurement optical system 200 has a light projection optical system 210 and a light receiving optical system 220 in the transmission direction of the beam splitter 230. The light projection optical system 210 includes a light source 211, a relay lens 212, a hole mirror 213, a prism 214, an objective lens 216, and the like. The light source 211 is in an optically conjugate position with the fundus. The opening of the hole mirror 213 is in an optically conjugate position with the pupil. The prism 214 is disposed at a position that is not optically conjugate with the pupil, and the light beam passing through the prism 214 is decentered with respect to the optical axis N1. The prism 214 is driven to rotate around the optical axis N1 by a drive unit 215. Instead of the prism 214, a parallel flat plate may be disposed obliquely on the optical axis N1.

[0032] The light receiving optical system 220 includes an objective lens 216, a prism 214, a hole mirror 213, a relay lens 221, a total reflection mirror 222, a light receiving aperture 223, a collimator lens 224, a ring lens 225, an image sensor 226, and the like. In the light receiving optical system 220, the objective lens 216, the prism 214, and the hole mirror 213 are shared with the light projecting optical system 210. The light receiving aperture 223 is in an optically conjugate positional relationship with the fundus. The ring lens 225 is in an optically conjugate positional relationship with the pupil. The image sensor 226 is in an optically conjugate positional relationship with the fundus.

[0033] In such a configuration of the measurement optical system 200, the measurement light beam emitted from the light source 211 passes through the relay lens 212, the hole mirror 213, the prism 214, the objective lens 216, and the beam splitter 230, and is projected as a spot-shaped light beam on the fundus. As a result, a point light source image is formed on the fundus. At this time, the prism 214 rotates around the optical axis N1, and the pupil projection image (projection light beam on the pupil) at the opening of the hole mirror 213 is eccentrically rotated at high speed. The reflected light beam reflected by the fundus is reflected by the hole mirror 213 via the beam splitter 230, the objective lens 216, and the prism 214. The reflected light beam further passes through the relay lens 221, is reflected by the total reflection mirror 222, is focused at the position of the light receiving aperture 223, and is imaged by the collimator lens 224 and the ring lens 225 as a ring-shaped image (ring image) on the image sensor 226. An output signal from the image sensor 226 is input to the control unit 70, which calculates the eye refractive power.

[0034] <Fixation target optical system> The fixation target optical system 300 has a light source 301, a fixation target plate 302, a light projecting lens 303, a total reflection mirror 304, a half mirror 305, an objective lens 306, and the like, in the reflection direction of the beam splitter 230. The fixation target plate 302 is illuminated by the light source 301, so that a fixation target is presented to the subject's eye E. The fixation target plate 302 is used when the subject's eye E is fixated and its ocular refractive power is measured. The driving unit 307 can move the fixation target plate 302 in the direction of the optical axis N2 to move the presentation position of the fixation target relative to the subject's eye E. The driving unit 307 can also fog the subject's eye E by moving the light source 301 and the fixation target plate 302 in the direction of the optical axis N2.

[0035] The driving unit 307 may change the presentation position of the fixation target by moving the light projecting lens 303 in the direction of the optical axis N2 relative to the fixation target plate 302. Therefore, the driving unit 307 may add fog to the subject's eye E by moving the light projecting lens 303 in the direction of the optical axis N2 relative to the fixation target plate 302.

[0036] <Target projection optical system> The index projection optical system 400 includes a first index projection optical system and a second index projection optical system. The first index projection optical system projects an alignment index at infinity onto the cornea of ​​the test eye E. The second index projection optical system projects an alignment index at finite distance onto the cornea of ​​the test eye E.

[0037] The first target projection optical system includes point light sources 401a and 401b, collimator lenses 402a and 402b, etc. The point light sources 401a and 401b emit near-infrared light. The collimator lenses 402a and 402b convert the light beam emitted by the point light sources into a parallel light beam (approximately parallel light beam). For example, a plurality of these point light sources and collimator lenses are arranged at 45 degree intervals on a concentric circle based on the optical axis N1 and symmetrically on both sides of a vertical plane passing through the optical axis N1.

[0038] The second target projection optical system has point light sources 403a and 403b. The point light sources 403a and 403b emit near-infrared light. For example, a plurality of these point light sources are arranged at an angle narrower than that of the point light sources of the first target projection optical system, and are symmetrical with respect to a vertical plane passing through the optical axis. The second target projection optical system can also be used as an anterior segment illumination for illuminating the anterior segment of the subject's eye E, as a target for measuring the corneal shape of the subject's eye E, and the like.

[0039] The index projection optical system 400 may be configured to project at least one of a dot-shaped index, a ring-shaped index (such as a so-called Mayer ring), a line-shaped index, and the like.

[0040] <Observation optical system> The observation optical system 500 has an objective lens 306, a half mirror 305, an imaging lens 501, an imaging element 502, etc., in the reflection direction of the beam splitter 230. The imaging element 502 is in an optically conjugate positional relationship with the anterior segment of the subject's eye E, and receives a reflected light beam from the anterior segment. In this way, an anterior segment image (front image of the anterior segment) of the subject's eye E is captured. A transillumination image, which is a type of anterior segment image, may also be captured. An output signal from the imaging element 502 is input to the control unit 70 and the display unit 75. The observation optical system 500 also serves as an optical system for detecting an alignment target image formed on the cornea of ​​the subject's eye E, and the position of the alignment target image is detected by the control unit 70.

[0041] <Facial illumination optical system> The face illumination optical system 600 includes an illumination light source 601. The illumination light source 601 may be a light source with low directivity. The illumination light source 601 may also be a light source that emits infrared light.

[0042] <Facial imaging optical system> The face photographing optical system 700 includes an imaging lens 701, an imaging element 702, etc. The imaging element 702 receives a light beam reflected from the face. This captures a face image including at least one of the left eye and the right eye of the subject's eye E. An output signal from the imaging element 702 is input to the control unit 70 and the display unit 75.

[0043] In this embodiment, the face photographing optical system 700 includes a wide-angle lens as the imaging lens 701, so that the subject's face can be photographed with a wide angle of view. For example, the angle of view may be 87° or more. This makes it easier for both eyes of the subject to be included in the face image. In addition, in this embodiment, a visible light cut filter may be disposed in the optical path of the face photographing optical system 700. This limits noise light due to visible light when photographing the subject's face. Here, the reflected light of infrared light from the face is detected by the imaging element 702, but in this case, there is a possibility that noise light due to infrared light may be incident. For this reason, the gain of the imaging element 702 may be adjusted to reduce the influence of noise due to infrared light.

[0044] <Control Unit> The control unit 70 includes a CPU (processor), a RAM, a ROM, etc. The CPU controls the driving of each part in the eye refractive power measurement device 1. The RAM temporarily stores various information. The ROM stores various programs executed by the CPU, etc. The control unit 70 may be configured with multiple control units (i.e., multiple processors).

[0045] The control unit 70 is electrically connected to the driving unit 4, the display unit 75 (operation unit 76), the non-volatile memory 72 (hereinafter, memory 72), the announcement unit 89, etc. Also, the control unit 70 is electrically connected to the light sources, the image pickup devices, the driving units, etc., provided in the measurement unit 100.

[0046] The memory 72 is a non-transient storage medium that can retain stored contents even if the power supply is cut off. For example, a hard disk drive, a flash ROM, a USB memory, etc. can be used as the memory 72. The memory 72 may store the measurement results of the subject's eye E (for example, eye refractive power, eye position information, etc.).

[0047] <Control action> The control operation of the eye refractive power measuring apparatus 1 having the above-mentioned configuration will be described.

[0048] The eye refractive power measurement device 1 in this embodiment outputs audio announcements to guide the subject through the examination, and objectively measures the eye refractive power of the subject's eye by fully automatically executing the processes from aligning the subject's eye E with the measurement unit 100 to acquiring the measurement data.

[0049] In addition, the eye refractive power measuring device 1 in this embodiment can select the first mode or the second mode as appropriate depending on the test situation of the subject. For example, the first mode may be set when an examiner is present during the test of the subject and guides the subject to the device while talking to the subject. In addition, the second mode may be set when the subject operates the device himself / herself to automatically proceed with the test.

[0050] <When the examiner is present during the examination of the examinee (first mode)> The following describes the case where the examiner is present during the examination of the subject (first mode). In this embodiment, when the eye refractive power measurement device 1 is started, the first mode is selected as the initial setting, and the voice announcement is set to an initial language such as an official language (here, "English"). For example, in the first mode, an examination screen is displayed on the display unit 75.

[0051] FIG. 3 is an example of an examination screen displayed on the display unit. FIG. 3(a) shows a state in which the language of the voice announcement is set to the initial language. FIG. 3(b) shows a state in which a list of languages ​​of the voice announcement that can be set is displayed on the examination screen. The examination screen 800 has a mode switching button 802, a language call button 803, an announcement language screen 804, a setting change button 805, and the like. The mode switching button 802 is a button for switching from a first mode to a second mode described later. The language call button 803 is a button for changing the voice announcement from the initial language to a desired language. For example, the examiner operates the language call button 803 to call up the announcement language screen 804. The announcement language screen 804 is a screen that displays a list of languages ​​of the voice announcement that the device can output. For example, the examiner selects a desired language from the list of languages, and the voice announcement is set to an arbitrary language. The setting change button 805 is a plurality of buttons for changing various settings. As an example, buttons for changing various settings such as selection of the subject's eye (measurement eye), change of examination items, etc. The observation image 801 is at least one of a face image of the subject captured by the face capturing unit 90, an anterior eye image captured by the measurement unit 100, etc. For example, the observation image 801 is captured by the subject placing his / her face on the chin rest, and the image is displayed.

[0052] <Voice announcement language setting> The examiner talks with the subject and guides the subject to the device. At this time, if the examiner determines that the subject cannot understand the initial language, the examiner changes the language of the audio announcement from the initial language to a desired language after confirming a language that the subject can understand. For example, the examiner presses the language call button 803 on the examination screen 800. The control unit 70 displays an announcement language screen 804 based on an input signal from the language call button 803. For example, the examiner selects an arbitrary language that the subject can understand from a list of languages ​​on the announcement language screen 804. The control unit 70 changes the audio announcement from the initial language to an arbitrary language based on an input signal from the announcement language screen 804. This changes the language of the audio announcement to the desired language.

[0053] When the control unit 70 completes setting the language for the voice announcement, it closes the announcement language screen 804 and displays the selected language on the language call button 803. For example, in this embodiment, when "Japanese" is selected from the list of languages, "Japanese" is displayed on the language call button 803, and the voice announcement is switched to Japanese.

[0054] The examiner changes the language of the voice announcement and, if necessary, changes various test settings, and then presses an examination start button (not shown) to start the examination of the subject's eye. In response to an input signal from the examination start button, the control unit 70 causes the announcement unit 89 to output a voice announcement in Japanese instructing the subject to place his or her face on the chin rest. The subject places his or her face on the chin rest in accordance with the voice announcement.

[0055] <Objective measurement> When the control unit 70 detects that the subject's face is placed on the chin rest 3b based on the detection result of the chin rest sensor 3c provided on the chin rest 3b of the face support unit 3, the control unit 70 causes the announcement unit 89 to output a voice announcement in Japanese instructing the subject to fixate the fixation target. The control unit 70 also turns on the light source 301 of the fixation target optical system 300, the light source of the target projection optical system 400, and the illumination light source 601 of the face illumination optical system 600. This illuminates the subject's face, and a facial image of the subject is captured. The control unit 70 causes the display unit 75 to display the facial image as an observation image 801.

[0056] When the control unit 70 detects the subject's eye from the observation image 801 (face image), it moves the photographing unit 100 in the XYZ directions based on the three-dimensional position information of the subject's eye, and completes the rough alignment of the photographing unit 100 with respect to the subject's eye. This allows an anterior eye image of the subject's eye E to be captured. The control unit 70 switches the observation image 801 from the face image to the anterior eye image and displays it on the display unit 75. Next, when the control unit 300 detects the subject's eye from the observation image 801 (anterior eye image), it moves the photographing unit 100 in the XYZ directions using the alignment target image, and completes the fine alignment of the photographing unit 100 with respect to the subject's eye.

[0057] The control unit 70 controls the measurement optical system 200 based on an input signal indicating the completion of alignment of the subject's eye, irradiates the measurement light onto the fundus of the subject's eye, and measures the ocular refractive power of the subject's eye based on the detection result of the measurement light reflected by the fundus. For example, the control unit 70 may specify the position of the ring image in each meridian direction, approximate it by the least squares method or the like, and obtain the ocular refractive power based on the approximated shape of the ring image. When the control unit 70 completes the measurement of one of the subjects' eyes, it moves the measurement unit 100 to the other eye and performs alignment and measurement of the ocular refractive power.

[0058] <Initialization> When the measurement of the eye refractive power of the subject's eye is completed, the control unit 70 outputs the measurement result (measurement data). For example, the control unit 70 may display the measurement result on the examination screen 800, print it out, or output it to the outside of the device wirelessly or wired. The examiner checks the measurement result of the subject's eye E and presses an examination end button (not shown) to end the examination of the subject's eye. The control unit 70 clears the measurement result displayed on the examination screen 800 in response to an input signal from the examination end button. In addition, the control unit 70 returns the language of the voice announcement to the initial language (i.e., from Japanese to English in this embodiment) in response to an input signal from the examination end button, and displays the examination screen 800 (see FIG. 3a) in which the voice announcement is set to the initial language on the display unit 75. This completes the initialization of the eye refractive power measurement device 1.

[0059] For example, when the first mode is set in this way, for subjects who can understand the initial language of the audio announcement, there is no need to set (change) the language of the audio announcement, and the test can be performed smoothly. For subjects who cannot understand the initial language of the audio announcement, the announcement language screen 804 can be called up using the language call button 803 as appropriate, and the audio announcement can be changed to a desired language from the list of languages ​​on the announcement language screen 804, so that the language of the announcement suitable for the subject can be easily set. Note that when the audio announcement is changed from the initial language to a different language, the audio announcement is set back to the initial language after the test is completed, so that the effort of resetting the language of the audio announcement is reduced. Furthermore, the time required for such an operation is reduced.

[0060] <When the subject conducts the test by himself / herself (second mode)> The following describes the case where the subject proceeds with the test by himself (second mode). In this embodiment, the first mode is selected as the initial setting when the eye refraction measuring device 1 is started, but the setting can be switched from the first mode to the second mode by pressing the mode switching button 802 on the test screen 800 (see FIG. 3(a)). In the second mode, the subject is required to select a language that he or she can understand each time a new subject is selected, so the voice announcement does not necessarily have to be set to an initial language such as an official language.

[0061] For example, when testing various subjects who have different native languages, the examiner may press the mode switching button 802 on the test screen 800 to set the second mode. Based on an input signal from the mode switching button 802, the control unit 70 changes the display on the display unit 75 from the test screen 800 to a language selection prompting screen. For example, the language selection prompting screen is a screen for allowing the subject to select the language of the audio announcement by himself / herself.

[0062] FIG. 4 is an example of a language selection prompting screen displayed on the display unit. For example, the language selection prompting screen 810 has an operation instruction screen 811, a language selection button 812, a mode switching button 813, and the like. The operation instruction screen 811 is a screen showing operation instructions (guidance information) for allowing the subject to select a language for the voice announcement. For example, the operation instructions may be text written in each language that the device can output, indicating that a desired language should be selected. The language selection button 812 is a button for allowing the subject to select a desired language for the voice announcement. For example, the language selection button 812 is provided with a list of a plurality of buttons corresponding to text in each language in the operation instructions. The mode switching button 813 is a button for switching from the second mode to the above-mentioned first mode. The mode switching button 813 may be locked so as to prohibit the subject from operating it.

[0063] <Voice announcement language setting> For example, the subject sits in front of the eye refractive power measuring device 1 according to the examiner's instructions, and checks the display unit 75 on which the language selection prompting screen 810 is displayed. For example, the control unit 70 constantly displays the language selection prompting screen 810 as a standby screen until an input signal is detected from the language selection button 812. The examiner selects the language selection button 812 corresponding to the desired language that the subject can understand, according to the operation instructions on the operation instruction screen 811. The control unit 70 sets the language of the voice announcement based on the input signal from the language selection button 812. For example, when the subject checks the operation instruction screen 811 and understands the Japanese sentence to select the desired language, the button "1. Japanese" is pressed from the list of language selection buttons 812. The control unit 70 sets the language of the voice announcement to Japanese based on the input signal from the language selection button 812.

[0064] When the control unit 70 completes the setting of the language for the voice announcement, it switches the display on the display unit 75 from the language selection prompting screen 810 to the examination screen 800, and automatically starts the examination. For example, the control unit 70 causes the announcement unit 89 to output a voice announcement in Japanese instructing the subject to place his / her face on the chin rest. The subject places his / her face on the chin rest in accordance with the voice announcement.

[0065] <Objective measurement> For example, when the control unit 70 detects that the face of the subject is placed on the chin rest 3b, it displays the observation image 801 on the examination screen 800 and performs alignment of the subject's eye and measurement of the eye refractive power. This is similar to the first mode, so the description will be omitted. Note that the selection of the eye to be measured and the examination items in the objective measurement (various examination settings) may be set in advance when the examiner sets the second mode.

[0066] Here, for example, if the subject mistakenly operates each button on the examination screen 800, the device may malfunction, the settings of the device may be changed, or the measurement of the eye refractive power may be stopped. For this reason, for example, the control unit 70 may detect an input signal from the language selection button 812, set the language of the announcement, and then disable the input of an operation signal from the examination screen 800 (display unit 75). That is, the control unit 70 may prohibit the change of settings or the execution of operations based on the operation signal. In addition, for example, the control unit 70 may superimpose a message screen (guidance, instruction, etc.) such as "Measurement in progress" or "Do not touch the screen" on the examination screen 800. Of course, the fact that the input of the operation signal on the examination screen 800 is disabled may be notified by a voice announcement. This reduces the possibility that the device may malfunction, the settings of the device may be changed, or the measurement of the eye refractive power may be stopped, and the examination can be performed smoothly.

[0067] <Initialization> When the measurement of the eye refractive power of the subject's eye is completed, the control unit 70 outputs the test results (measurement data). Furthermore, when a certain time has elapsed since the end of the measurement, the control unit 70 causes the display unit 75 to display the language selection prompt screen 810 again. At this time, the control unit 70 cancels the disablement of the input of the operation signal on the display unit 75. This completes the initialization of the eye refractive power measurement device 1.

[0068] When the next subject is selected, the next subject selects a desired language for the voice announcement from the language selection button 812. For example, the button "3. Italian" is pressed from the list of language selection buttons 812. Based on the input signal from the language selection button 812, the control unit 70 changes the language setting for the voice announcement from Japanese, which was selected by the previous subject, to Italian, which was selected by the next subject. Of course, the control unit 70 may clear the setting of the language selected by the previous subject before causing the language selection prompting screen 810 to be displayed on the display unit 75.

[0069] For example, when the second mode is set in this way, the subject can easily set the language of the voice announcement that the subject can understand by checking the operation explanation screen 811 of the language selection prompting screen 810. Furthermore, when the test for the previous subject is completed and the next subject is to be tested, the language selection prompting screen 810 is displayed, so the examiner does not need to change the language setting of the voice announcement, and it is possible to efficiently accommodate cases where the subjects' native languages ​​are different.

[0070] As described above, for example, the ophthalmic apparatus of this embodiment displays a first language setting screen (for example, language selection guidance screen 810) for setting the language of the announcement, which is different from the condition setting screen for setting the examination conditions of the subject's eye, and outputs an announcement in the selected language from the notifying means based on an operation signal from the operating means for selecting the language of the announcement, and proceeds with the examination of the subject's eye. The first language setting screen is a screen on which any language can be selected based on a list of multiple languages, and the first language setting screen is displayed as an initial screen every time the examination of the subject's eye is completed. For example, in an ophthalmic apparatus in which the language of the announcement is set in advance to a predetermined language (for example, an official language), if the subject cannot understand the language of the announcement, it is necessary to change the language setting of the announcement and perform the examination. Furthermore, after the examination is completed, it is necessary to return the changed language setting of the announcement to the original language (official language). However, in the ophthalmic apparatus of this embodiment, the first language setting screen is displayed every time the examination of the subject's eye is completed, and the examination can be started after selecting a desired language each time the subject changes, and the language of the announcement suitable for the subject can be easily set.

[0071] Also, for example, in the ophthalmologic apparatus of this embodiment, the first language setting screen includes guidance information (for example, an operation explanation screen 811) for guiding the selection of the announcement language, and setting buttons corresponding to a plurality of languages ​​(for example, a language selection button 812), and based on an operation signal from the setting button, an announcement is output in the selected language, and the examination of the subject's eye is progressed. This allows, for example, the announcement language suitable for the subject to be easily set by using the guidance information, and therefore the examination can be carried out smoothly.

[0072] For example, the ophthalmic device of this embodiment has a first mode in which a condition setting screen is displayed as an initial screen every time the examination of the subject's eye is completed, and a second mode in which a first language setting screen is displayed as an initial screen every time the examination of the subject's eye is completed, and displays the condition setting screen or the first language setting screen according to the selected mode. For example, in the first mode, when the subject cannot understand the language of the announcement, the language can be changed from a predetermined language to the language desired by the subject as appropriate. For example, in the second mode, the language of the announcement can be selected in advance according to the language used by the subject every time the subject changes. In this way, the ophthalmic device of this embodiment can easily select the language of the announcement desired by the subject by switching the mode according to various examination situations, and the examination can be performed smoothly.

[0073] Also, for example, in the ophthalmologic apparatus of this embodiment, the first mode is a mode for the examiner to select the language of the announcement, and the second mode is a mode for the subject to select the language of the announcement. For example, when the examiner proceeds with the examination while talking to the subject, the first mode may be selected, and the language may be changed when the subject cannot understand the preset language of the announcement. Also, for example, when the subject proceeds with the examination by himself, the second mode may be selected, and the subject may change the language of the announcement that he can understand by himself, and the examination may proceed according to the changed voice announcement. This allows, for example, the mode to be appropriately switched depending on the presence or absence of the examiner, and the examination can be performed smoothly.

[0074] Also, for example, in the ophthalmologic apparatus of this embodiment, the condition setting screen is an examination screen (e.g., examination screen 800) including at least an observed image of the subject's eye and a call button for calling a second language setting screen (e.g., announcement language screen 804) for setting the language of the announcement. For example, when the examiner is setting the conditions for the examination on the examination screen and the subject cannot understand the language of the announcement set in advance, the examiner can easily set the language suitable for the subject by pressing the call button.

[0075] Also, for example, the ophthalmologic apparatus of this embodiment sets the language of announcements to a preset initial language every time an examination of a subject's eye is completed. For example, if a subject is unable to understand the initial language of announcements (as an example, an official language) and changes the language setting of announcements, it is necessary to return the language to the original language (official language) after the examination is completed, which requires a lot of work. However, in the ophthalmologic apparatus of this embodiment, the announcements are set to the initial language every time an examination of a subject's eye is completed, thereby reducing the work of returning the language setting of announcements to the initial language every time it is changed. Also, the time required for such an operation is reduced.

[0076] Also, for example, when the second mode is set, the ophthalmic apparatus of this embodiment changes the operation control for prohibiting the operation of the ophthalmic apparatus after the announcement language is selected. For example, the subject may operate the ophthalmic apparatus or change the settings, which may prevent the examination of the subject's eye from proceeding properly. However, by changing the operation control for prohibiting the operation according to the setting of the second mode, the examination of the subject's eye can proceed properly.

[0077] <Example of transformation> In this embodiment, the test screen 800 and the language selection prompting screen 810 (see FIG. 4) are displayed on the same display unit 75, but the present invention is not limited to this. For example, the test screen 800 and the language selection prompting screen 810 may be displayed on different display units. As an example, a first display unit (display unit 75) and a second display unit different from the first display unit may be provided, and the language selection prompting screen 810 may be displayed on the second display unit.

[0078] In the present embodiment, the subject operates the language selection button 812 on the language selection prompting screen 810 to change the language of the voice announcement for proceeding with the examination of the subject's eye E, but the present invention is not limited to this. For example, when instructions or guidance for the subject are displayed as messages on the display unit 75, the subject may operate the language selection button 812 to change the language of such messages.

[0079] In the present embodiment, the announcement language screen 804 displaying a list of languages ​​for the voice announcement in the first mode and the language selection prompting screen 810 displaying a list of languages ​​for the voice announcement in the second mode are different screens, but the present invention is not limited to this. For example, the announcement language screen 804 in the first mode may be configured as the same screen as the language selection prompting screen 810 in the second mode. In this case, when the examiner presses the language call button 803 in the first mode, the control unit 70 may display the language selection prompting screen 810 on the display unit 75 based on an input signal from the language call button 803. This causes the language selection button 812 to be displayed together with the operation instructions on the operation instruction screen 811, so that the examiner can change the voice announcement from the initial language to a desired language using the language selection button 812. When the setting of the language for the voice announcement is completed, the control unit 70 closes the language selection prompting screen 810 and displays the examination screen 800 on the display unit 75. For example, when the first mode is set in this manner, the language of the audio announcement can be easily set to a language suitable for the subject by using the language selection prompting screen 810 to change the language of the audio announcement.

[0080] In addition, in this embodiment, a case has been described in which a desired language is selected by operating the language call button 803 on the examination screen 800 (see FIG. 3(a)) before starting the examination of the subject's eye E in the first mode, but this is not limiting. For example, the language call button 803 may be constantly displayed on the examination screen 800, and the language call button 803 can be operated even after the examination of the subject's eye E has started. For this reason, the examiner may change the language of the audio announcement while checking the situation, such as whether the examination of the subject's eye E is not progressing.

[0081] In the present embodiment, the second mode is described by displaying the operation instruction screen 811 on the language selection prompting screen 810 (see FIG. 4) to allow the subject to select a desired language, but the present invention is not limited to this. For example, the operation instruction screen 811 may be displayed on the language selection prompting screen 810, and the content of the operation instruction screen 811 may be output to the announcement unit 89 as a voice announcement. For example, voice announcements such as "On this screen, you can select the voice guidance language. Please press the button for the desired language" or "On this screen, you can select the voice guidance language. The language currently being guided is number 1" may be output in each language in turn.

[0082] In the present embodiment, the operation instruction screen 811 of the language selection prompting screen 810 (see FIG. 4) displays the operation instruction in each language in the second mode, but the present invention is not limited to this. For example, the operation instruction on the operation instruction screen 811 may be displayed as an icon or the like that can prompt the subject to select the announcement language.

[0083] In addition, in this embodiment, the configuration in which the switching between the first mode and the second mode is performed by operating the mode switching button 813 provided on each of the examination screen 800 and the language selection prompting screen 810 has been described as an example, but the present invention is not limited to this. For example, the switching between the first mode and the second mode may be performed by operating a button, an icon, or the like arranged on a home screen that awaits the examiner's operation.

[0084] 5 is an example of a home screen displayed on the display unit 75 of the eye refraction measurement device 1. In this embodiment, a home screen 900 may be displayed on the display unit 75 when the eye refraction measurement device 1 is started up. For example, the home screen 900 is a screen that is the basis of screen transitions. For example, the home screen 900 is a screen before transitioning to another screen. For example, the home screen 900 can transition to various screens.

[0085] On the home screen 900, an ID input button 910, a measurement eye selection button 911, a mode selection button 914, a screen transition button 912, and the like are displayed. The ID input button 910 is a button for inputting an ID. When the ID input button 910 is pressed, the control unit 70 displays an input screen (for example, a keyboard screen, etc.) for inputting an ID. The measurement eye selection button 911 is a button for selecting binocular measurement or monocular measurement. The mode selection button 914 is a button for setting the first mode or the second mode. When the mode selection button 914 is pressed, the control unit 70 displays an input screen for selecting one of the modes. Of course, the mode selection button 914 may be directly selectable on the home screen 900, like the measurement eye selection button 911. The screen transition button 912 is a button for transitioning the home screen 900 to a screen corresponding to the first mode or the second mode.

[0086] The examiner operates various buttons to set the examination conditions for the subject's eye E, and presses the screen transition button 912. The control unit 70 transitions to the examination screen 800 when the first mode is set, and transitions to the language selection guidance screen 810 when the second mode is set, based on an input signal from the screen transition button 912. In the eye refractive power measuring device 1 of this embodiment, the first mode and the second mode may be selected via the home screen 900 in this manner. Note that when switching between the modes, the home screen 900 may be called from the examination screen 800 or the language selection guidance screen 810.

[0087] In this embodiment, the configuration has been described as an example in which, in the first mode, the inspection screen 800 having the observation image 801 and the language call button 803 is displayed on the display unit 75 as a screen on which inspection conditions including the language of the voice announcement can be set, but the present invention is not limited to this. For example, in the first mode, the above-mentioned home screen 900 may be displayed on the display unit 75 as a screen on which inspection conditions can be set. In this case, the home screen 900 may display a language selection button 913, and by operating the language selection button 913, a list of languages ​​of the voice announcement that the device can output may be displayed.
