Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the remote operation by the examiner, the subject may want to interact with the examiner. Further, since remote operation by the examiner is possible, it is possible to remotely operate a plurality of ophthalmic devices using one host device. For this reason, when one examiner interacts with a plurality of subjects at the same time, there is a problem that appropriate interaction becomes difficult.

[0005] The present disclosure has been made paying attention to the above problems, and an object thereof is to provide an ophthalmic system in which when an examiner remotely operates a plurality of ophthalmic devices using one host device, one examiner can individually interact with a plurality of subjects.

Means for Solving the Problems

[0006] The ophthalmic system of the present disclosure includes a plurality of ophthalmic devices and one host device located at a position remote from each of the ophthalmic devices. Each of the ophthalmic devices and the host device can communicate with each other, and an examiner operates each of the ophthalmic devices remotely using the host device. In the ophthalmic system, each of the ophthalmic devices and the host device has a microphone and a speaker, respectively. The ophthalmic system has an interactive function that enables the subject on the side of each ophthalmic device and the examiner on the side of the host device to interact with each other. When the interactive function is on for two or more of the plurality of ophthalmic devices, the host device maintains the on state of the interactive function in one of the ophthalmic devices and issues an instruction to temporarily suspend the interactive function for the remaining ophthalmic devices.

Advantages of the Invention

[0007] According to the ophthalmic system of the present disclosure, when an examiner remotely operates a plurality of ophthalmic devices using one host device, one examiner can interact individually with a plurality of subjects.

Mode for Carrying Out the Invention

[0009] The mode for implementing the ophthalmic system according to the present disclosure will be described as follows based on Example 1 shown in the drawings. Among the XYZ directions (three - axis directions) orthogonal to each other in the figure, the Y - direction is the vertical direction. The Z - direction is the front - rear direction (operating distance direction) parallel to the forward direction approaching the subject's eye to be examined (not shown) and the rear direction moving away from the subject. Also, the X - direction is the left - right direction perpendicular to both the vertical direction and the front - rear direction.

Example

[0010] The ophthalmic system 1 applied to Example 1 will be described with reference to FIGS. 1 and 2. The ophthalmic system 1 includes three ophthalmic devices 10. The three ophthalmic devices 10 are the first ophthalmic device 10A, the second ophthalmic device 10B, and the third ophthalmic device 10C.

[0011] Hereinafter, when the ophthalmic device 10 is not particularly distinguished, only the numerical symbol "10" is attached. For example, a plurality of ophthalmic devices 10, three ophthalmic devices 10, each ophthalmic device 10, one ophthalmic device 10, the remaining ophthalmic devices 10, the ophthalmic device 10, etc. Also, when distinguishing three ophthalmic devices 10, the first ophthalmic device 10A, the second ophthalmic device 10B, and the third ophthalmic device 10C are used, and in addition to the numerical symbol "10", an alphabet is attached. Furthermore, when the configurations included in the ophthalmic device 10 are not particularly distinguished, only numerical symbols are attached. Also, for the configurations respectively included in the three ophthalmic devices 10, in addition to the numerical symbols corresponding to each configuration, an alphabet is attached. When the alphabet "A" is attached, it is the configuration included in the first ophthalmic device 10A. When the alphabet "B" is attached, it is the configuration included in the second ophthalmic device 10B. When the alphabet "C" is attached, it is the configuration included in the third ophthalmic device 10C. Furthermore, in Example 1, it is assumed that the first ophthalmic device 10A, the second ophthalmic device 10B, and the third ophthalmic device 10C have the same configuration. However, the three ophthalmic devices 10 are not limited to having the same configuration.

[0012] The ophthalmic system 1 includes one remote operation device 30 (host device). The remote operation device 30 is located at a remote position from the three ophthalmic devices 10. In other words, the three ophthalmic devices 10 and the remote operation device 30 are located at separated positions (places). For example, the three ophthalmic devices 10 and the remote operation device 30 are respectively arranged in adjacent rooms. Or, the remote operation device 30 is arranged in the hospital where the examiner belongs, and the three ophthalmic devices 10 are arranged at a remote location away from the hospital. For this reason, the examiner is at the place where the remote operation device 30 is arranged, and each subject is at the place where each ophthalmic device 10 is arranged. The three ophthalmic devices 10 may be arranged in the same room or at positions (places) separated from each other.

[0013] The remote operation device 30 is connected to a communication network such as the Internet 101 via a router 100 (router device). The remote operation device 30 is connected to each ophthalmic device 10 via the Internet 101. Thereby, remote operation by the examiner is possible.

[0014] As shown in FIG. 2, the ophthalmic device 10 is placed on the ophthalmic examination table 200 and used for examining the eye to be examined. The ophthalmic device 10 is a composite device capable of measuring the intraocular pressure value, refractive power, corneal curvature, etc. of the eye to be examined. Therefore, by the remote operation of the examiner, the ophthalmic device 10 measures various eye characteristics such as the intraocular pressure value, refractive power, and corneal curvature (corneal shape) of the eye to be examined. The ophthalmic device 10 includes a base portion 11, a face support portion 12, a drive mechanism 13, a measurement head 14, a monitor portion 15 (display portion), a subject speaker 16 (speaker), a subject microphone 17 (microphone), a subject camera 18 (camera), and a device control portion 20 (control portion, see FIG. 2).

[0015] The base portion 11 supports members such as the face support portion 12 and the drive mechanism 13 placed on the upper side of the base portion 11.

[0016] The face support portion 12 supports the face of the subject. The face support portion 12 is disposed in front of the drive mechanism 13. The face support portion 12 integrally includes a chin support portion 12a, a forehead abutment portion 12b, a pair of frames 12c, and a base portion 12d. The base portion 12d is fixed in front of the base portion 11. The chin support portion 12a receives the chin of the subject. The chin support portion 12a is provided above the central portion of the base portion 12d. The forehead abutment portion 12b abuts against the forehead of the subject. The pair of frames 12c are provided on both sides of the base portion 12d, and the forehead abutment portion 12b is connected to the upper ends thereof. The subject faces the ophthalmic device 10 in a state of sitting on a chair or the like (not shown) provided in front of the ophthalmic device 10. Next, the subject undergoes an examination with the chin placed on the chin support portion 12a and the forehead abutting against the forehead abutment portion 12b.

[0017] The drive mechanism 13 corresponds to the relative movement mechanism of the ophthalmic device 10. The drive mechanism 13 is constituted by an actuator (not shown) such as a motor, for example. The drive mechanism 13 is driven based on control information (control signal) from the device control unit 20. The drive mechanism 13 can move the jaw receiving portion 12a up and down in the Y direction based on the control information. Further, the drive mechanism 13 moves the measurement head 14 in the XYZ directions with respect to the base portion 11 based on the control information. Thereby, the measurement head 14 can be relatively moved in the XYZ directions with respect to the eye to be examined. In this way, the height of the jaw receiving portion 12a can be adjusted, and the alignment of the measurement head 14 in the XYZ directions with respect to the eye to be examined can be achieved.

[0018] Inside the measurement head 14, an optical system for known observation and photography is provided. Various eye characteristics of the subject can be observed and photographed by the optical system. Specifically, the measurement head 14 is provided with a plurality of types of various ophthalmic measuring devices including an auto-refractometer 141 and the like. The auto-refractometer 141 measures the refractive power and corneal curvature of the eye to be examined using various optical systems. Since the specific configuration of the auto-refractometer 141 is a known technique, the description thereof is omitted here. Note that not limited to the auto-refractometer 141, a non-contact tonometer or the like may be provided in the measurement head 14. The non-contact tonometer measures the intraocular pressure value of the eye to be examined without contact. In short, any device capable of performing an ophthalmic examination can be provided in the measurement head 14.

[0019] The monitor unit 15 is attached to the rear side of the upper surface of the measurement head 14. The monitor unit 15 is disposed, for example, at a position visible to the subject. That is, the orientation (angle) of the monitor unit 15 is the direction on the subject side (the direction in which the subject can visually observe the display of the monitor unit 15), and various information can be displayed from the examiner to the subject. For example, the monitor unit 15 faces forward of the ophthalmic device 10. Further, the orientation of the monitor unit 15 is the direction in which the subject can visually observe the display of the monitor unit 15 in both the state of standing in front of the ophthalmic device 10 and the state of sitting.

[0020] The monitor unit 15 is, for example, a touch panel type monitor, and a liquid crystal display is used. An image such as an observation image of the eye to be examined is displayed on the monitor unit 15 based on control information from the apparatus control unit 20. Measurement results of eye characteristics such as the intraocular pressure value, refractive power of the eye, and corneal curvature of the eye to be examined are displayed on the monitor unit 15. An operation menu screen or the like for performing various operations is displayed on the monitor unit 15. Further, the monitor unit 15 receives operation inputs for each operation menu screen. Thus, it is also possible for the subject himself / herself to directly operate the ophthalmic apparatus 10.

[0021] The subject speakers 16 are built into each of the pair of frames 12c. The positions of the respective subject speakers 16 are arranged near the left and right ears of the subject during eye examination.

[0022] The subject microphone 17 is built into the central part of the base 12d, in front of and below the chin rest 12a. The position of the subject microphone 17 is arranged near the mouth of the subject during eye examination.

[0023] The subject camera 18 is provided above the monitor unit 15. The subject camera 18 is provided at a position where the subject in the examination posture is reflected. For this reason, the subject camera 18 can photograph the subject in the examination posture and can also photograph the subject standing on the front side of the face support 12. In addition to this, the subject camera 18 is for peripheral photographing capable of photographing the periphery of the ophthalmic apparatus 10, that is, the front side of the position of the subject camera 18. The reason for photographing the subject standing on the front side of the face support 12 is to photograph the appearance of the subject who has come for the examination. Also, the reason for photographing the periphery of the ophthalmic apparatus 10 is to photograph the appearance of the subject who is not reflected on the front side of the face support 12.

[0024] Here, the inspection postures include the posture of the subject sitting on a chair or the like (not shown) provided in front of the ophthalmic device 10, the posture of the subject placing the chin on the chin support portion 12a and the forehead on the forehead rest portion 12b, and the posture of the subject standing on the front side of the face support portion 12. As will be described later, the subject display information (photographed image, moving image, video, (video) display information) of the subject camera 18 is displayed on the examiner monitor unit 32, so that the examiner can confirm the subject display information. For this reason, the examiner can observe the state of the subject before, during, and after the inspection based on the display of the examiner monitor unit 32. In addition, the examiner can use the display of the examiner monitor unit 32 for position adjustment between the ophthalmic device 10 and the subject.

[0025] Next, the control system of the ophthalmic system 1 will be described as follows with reference to FIGS. 3 and 4.

[0026] In addition to the above configuration, as shown in FIG. 3, the ophthalmic device 10 includes a device control unit 20, a communication interface 21, and a remote operation reception unit 22.

[0027] The remote operation device 30 includes an operation unit 31, an examiner monitor unit 32, an examiner speaker 33 (speaker), an examiner microphone 34 (microphone), an examiner camera 35 (camera), and a main body control unit 36.

[0028] The communication interface 21 and the main body control unit 36 are connected to each other via the Internet 101 and the router 100. The communication interface 21 and the main body control unit 36 perform input and output of various information (control signals, etc.) with each other via the router 100 and the Internet 101. In the following description, the description of "via the router 100 and the Internet 101" may be omitted.

[0029] Since the ophthalmic device 10 is remotely operated by the examiner, the remote operation device 30 will be described first.

[0030] The remote operation device 30 is a device such as a personal computer or a tablet terminal. The remote operation device 30 is used when an examiner remotely operates the ophthalmic device 10.

[0031] The operation unit 31 uses, for example, a keyboard and a mouse. The operation unit 31 receives operation information for remotely operating the ophthalmic device 10 input by the examiner. The operation unit 31 outputs the input operation information to the main body control unit 36. The operation information includes, in addition to the examiner's input, information (signals) automatically output by the main body control unit 36 to the remote operation reception unit 22 based on various information such as the ophthalmic device 10.

[0032] The examiner monitor unit 32 uses, for example, a liquid crystal display. The examiner monitor unit 32 displays the display information input from the main body control unit 36. The display information is display information of the inspection mode of the ophthalmic device 10 or the sleep mode described later, subject display information of the subject camera 18, and the same display information as the display screen of the monitor unit 15 of the ophthalmic device 10.

[0033] An example of the display of the examiner monitor unit 32 is shown in FIG. 4. The examiner monitor unit 32 displays the subject and the like. Through the display of the examiner monitor such as FIG. 4, the examiner can recognize the states (situations) of each ophthalmic device 10 and each subject. On the examiner monitor unit 32, images 321 are displayed separately for every three ophthalmic devices 10. In the image 321 of each ophthalmic device 10, a subject photo 322, an ophthalmic device symbol 323, an inspection order number 324, an ophthalmic examination state 325, a function switch 326 (output means), a pause switch 327 (output means), and a resume switch 328 (output means) are displayed.

[0034] The subject photo 322 is a photo of the subject taken by the subject camera 18. The photo is a still image that captures the subject's face to confirm the identity of the subject. The still image may be changed every few seconds, or may not be changed if it is for recognizing the subject. Note that instead of the still image, the subject photo 322 may be a moving image of the subject.

[0035] The ophthalmic device symbol 323 is the symbol for each ophthalmic device 10. "A" is the first ophthalmic device 10A, "B" is the second ophthalmic device 10B, and "C" is the third ophthalmic device 10C.

[0036] The examination order number 324 indicates the order in which the subject is ready for the examination.

[0037] The ophthalmic examination status 325 indicates the status of the ophthalmic examination in each ophthalmic device 10. "During examination" indicates that the subject's ophthalmic examination is actually being performed. "On hold" indicates that the interactive function described later is on hold. "During examination guidance" indicates that the examination guidance process described later is being executed. In addition, there are "Absent" indicating that the subject is not present, "Waiting" indicating that the subject is waiting for the start of the ophthalmic examination in a state where the preparation for the examination is complete, and "Examination ended" indicating that the examiner's ophthalmic examination has ended.

[0038] The function switch 326 indicates whether the interactive function described later is on or off, and is a switch for switching the interactive function between on and off. A display with a white background and a black background indicates that the interactive function is on, and a display with black characters and a white background indicates that the interactive function is off.

[0039] The pause switch 327 indicates whether the interactive function is paused from being on, and is a switch for switching the interactive function from on to paused. A display with a white background and a black background indicates that the interactive function is paused, and a display with black characters and a white background indicates that the interactive function is not paused.

[0040] The resume switch 328 indicates whether the interactive function has been resumed from being paused, and is a switch for switching the interactive function from paused to resumed. A display with a white background and a black background indicates that the interactive function has been resumed, and a display with black characters and a white background indicates that the interactive function has not been resumed.

[0041] As shown in FIG. 3, the examiner speaker 33 and the examiner microphone 34 use, for example, a headset (headphone with a microphone). The examiner speaker 33 outputs the voice of the subject (subject voice information) input to the subject microphone 17. The examiner microphone 34 outputs the voice of the examiner (examiner voice information) input thereto to the main body control unit 36.

[0042] The examiner camera 35 is provided at a position where it can photograph the examiner (the examiner's figure) at least when the examiner is in a position where the remote control device 30 can be operated. As will be described later, the examiner display information (photographed image, moving image, video, (video) display information) of the examiner camera 35 is displayed on the monitor unit 15 and the examiner monitor unit 32, so that both the subject and the examiner can confirm the examiner display information. For this reason, the subject can recognize the presence of the examiner from the display on the monitor unit 15. Also, the examiner can confirm the display state of the examiner display information on the monitor unit 15 from the display on the examiner monitor unit 32. Here, "when the examiner is in a position where the remote control device 30 can be operated" includes during the examiner's remote control operation.

[0043] The main body control unit 36 includes an arithmetic circuit composed of various processors (Processors) and memories (storage units), etc. The various processors include a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an ASIC (Application Specific Integrated Circuit), and programmable logic devices [for example, SPLD (Simple Programmable Logic Devices), CPLD (Complex Programmable Logic Device), and FPGA (Field Programmable Gate Arrays)], etc. Note that the various controls (functions) of the main body control unit 36 may be realized by one processor or by a plurality of processors of the same type or different types.

[0044] The main control unit 36 outputs operation information, examiner voice information, examiner display information, etc. to the communication interface 21. Also, display information, subject voice information, etc. are input to the main control unit 36 from the communication interface 21. The main control unit 36 receives display information, subject voice information, etc., reads out and executes a control program stored in a memory (not shown), thereby controlling the operation of the remote control device 30. For example, in the case of display information, the main control unit 36 outputs it to the examiner monitor unit 32, and in the case of subject voice information, it outputs it to the examiner speaker 33. Also, the main control unit 36 outputs operation information, etc. to the device control unit 20 based on operation information, etc. input from the operation unit 31. The main control unit 36 stores the state (information) of each ophthalmic device 10 in the memory through communication with each ophthalmic device 10. The state of each ophthalmic device 10 is, for example, the on, off, pause (during pause), and resume states of the interactive function described later. Further, the main control unit 36 stores in the memory the order in which the interactive function of each ophthalmic device 10 is turned on (on control at the time of step S52 described later). In this way, the main control unit 36 integrally manages the states, etc. of each ophthalmic device 10.

[0045] Next, the ophthalmic device 10 will be described.

[0046] The communication interface 21 and the remote operation reception unit 22 constitute a LAN chip (LAN is an abbreviation for Local Area Network). The communication interface 21 receives operation information, examiner voice information, examiner display information, etc. from the main control unit 36. The communication interface 21 outputs operation information, examiner voice information, examiner display information, etc. to the remote operation reception unit 22. Also, display information, subject voice information, the state of each ophthalmic device 10, etc. are input to the communication interface 21 from the device control unit 20. The communication interface 21 outputs display information, subject voice information, the state of each ophthalmic device 10, etc. to the main control unit 36. Here, the LAN chip is an example of a member that operates and receives a signal for starting (restarting) a part of the ophthalmic device 10 that is in a paused state in the sleep mode described later.

[0047] The remote operation reception unit 22 receives operation information, examiner voice information, examiner display information, etc. from the communication interface 21. The remote operation reception unit 22 receives operation information, examiner voice information, examiner display information, etc., and outputs the operation information, examiner voice information, examiner display information, etc. to the device control unit 20. The remote operation reception unit 22 receives a wake signal or a sleep signal as operation information and outputs these signals to the device control unit 20. The remote operation reception unit 22 receives an on signal, an off signal, a pause signal, and a resume signal of the interactive function described later and outputs these signals to the device control unit 20.

[0048] Similar to the main control unit 36 described above, the device control unit 20 includes an arithmetic circuit composed of various processors, memories, etc. Note that various controls (functions) of the device control unit 20 may be realized by one processor or by a plurality of processors of the same type or different types.

[0049] Based on the operation information, examiner voice information, examiner display information, etc. input from the remote operation reception unit 22, the device control unit 20 reads and executes a control program stored in a memory (not shown), thereby controlling the operation of the ophthalmic device 10. Also, based on the subject voice, etc. input from the subject microphone 17, the device control unit 20 outputs subject voice information, etc. to the main control unit 36. The device control unit 20 functions as mode transition control, inspection guidance control, inspection execution control, display control, voice control, etc. Further, the device control unit 20 stores the state, etc. of the ophthalmic device 10 in the memory.

[0050] When the device control unit 20 receives a sleep signal from the remote operation reception unit 22, it performs control to turn off the power supply to all of the ophthalmic device 10 except for the communication interface 21 and the remote operation reception unit 22. Then, the device control unit 20 pauses the operation of the ophthalmic device 10 except for a part and shifts the ophthalmic device 10 to the sleep mode. Also, when the device control unit 20 receives a wake signal from the remote operation reception unit 22, it performs control to turn on the power supply to all of the ophthalmic device 10 and shifts the ophthalmic device 10 to the inspection mode.

[0051] Here, the sleep mode is a mode in which, among the ophthalmic device 10, a member that pauses some operations of the ophthalmic device 10 and receives a signal for starting (restarting) the paused part of the ophthalmic device 10 is operating. In other words, the sleep mode is a mode in which the ophthalmic device 10 pauses operations and waits for a signal for startup, that is, a paused state (waiting state). Also, since some operations of the ophthalmic device 10 are paused in the sleep mode, it is a mode (low power consumption state) in which the power consumption of the ophthalmic device 10 can be reduced compared to the inspection mode, and it can shift to the inspection mode faster than when the power of the ophthalmic device 10 is completely turned off. The inspection mode is a mode (activated state) in which inspections can be performed with the ophthalmic device 10.

[0052] Next, the processing flow of the ophthalmic device 10 will be described as follows using an example of the flowcharts from FIG. 5 to FIG. 9. In the flowcharts from FIG. 5 to FIG. 9, various information output from the main body control unit 36 is input to the device control unit 20 via the communication interface 21 and the remote operation reception unit 22. For this reason, in the description of the flowchart, the description of "via the communication interface 21" and "via the communication interface 21 and the remote operation reception unit 22" may be omitted. Conversely, various information output from the device control unit 20 is input to the main body control unit 36 via the communication interface 21. For this reason, the description of "via the communication interface 21" may be omitted.

[0053] First, the processing flow of the ophthalmic device 10 will be described as follows using an example of the flowchart in FIG. 5. Until the start of the examiner's remote operation, since the ophthalmic device 10 is in the sleep mode, the program starts the processing flow in the sleep mode. "Until the start of the examiner's remote operation" is, for example, until the start of a hospital examination.

[0054] In the sleep mode of the ophthalmic device 10 of Example 1, the operations of the chin rest portion 12a, the drive mechanism 13, the measurement head 14, the monitor portion 15, the subject speaker 16, the subject camera 18, and the device control unit 20 are suspended. Even in the sleep mode, the communication interface 21 and the remote operation reception unit 22 are operating. The communication interface 21 and the remote operation reception unit 22 are members that receive signals for starting (restarting) the ophthalmic device 10.

[0055] In step S1, following the start of the process, the remote operation reception unit 22 determines whether a wake signal has been received. If YES, the process proceeds to step S2; if NO, step S1 is repeated. When the ophthalmic device 10 is in the sleep mode, the ophthalmic device 10 waits for a wake signal from the main body control unit 36. When a wake signal is output from the main body control unit 36 due to an operation input on the operation unit 31 of the examiner, the remote operation reception unit 22 receives the wake signal. Then, the remote operation reception unit 22 determines that the wake signal has been received. Here, if the determination of non-reception of the wake signal continues, step S1 is repeated.

[0056] In step S2, following the reception of the wake signal in step S1, the remote operation reception unit 22 and the device control unit 20 execute an inspection mode transition process and proceed to step S3. In the inspection mode transition process, first, since the remote operation reception unit 22 received the wake signal in step S1, the remote operation reception unit 22 outputs the wake signal to the device control unit 20. As a result, the device control unit 20 starts (operates) upon receiving the wake signal. Next, the device control unit 20 performs control to start the chin rest portion 12a, the drive mechanism 13, the measurement head 14, the monitor portion 15, the subject speaker 16, and the subject camera 18. In other words, the device control unit 20 performs control to turn on all power supplies of the ophthalmic device 10.

[0057] Further, even when a wake signal is input, the apparatus control unit 20 does not perform control to activate the subject microphone 17. Next, the apparatus control unit 20 performs mode transition control to transition the ophthalmic apparatus 10 from the sleep mode to the inspection mode. Note that, after performing the mode transition control to transition the ophthalmic apparatus 10 from the sleep mode to the inspection mode, the apparatus control unit 20 may perform control to activate the ophthalmic apparatus 10 (such as the chin rest portion 12a) during the operation pause.

[0058] In step S3, following the inspection mode transition process in step S2, the determination of the retreat detection in step S7, or the determination of the non-reception of the sleep signal in step S11, the apparatus control unit 20 determines whether or not the posture of the subject has been detected. If YES, the process proceeds to step S4, and if NO, the process proceeds to step S11. Detection of the posture of the subject, that is, detection of the presence of the subject, is determined from the moving image (video) of the subject camera 18. First, the subject display information of the subject camera 18 is output from the subject camera 18 to the main body control unit 36 through the apparatus control unit 20. Thereby, the main body control unit 36 displays the subject display information on the examiner monitor unit 32 separately from FIG. 4. If FIG. 4 is a moving image, it may be displayed together with the display of FIG. 4. The main body control unit 36 displays the subject display information on the examiner monitor unit 32 while the subject camera 18 is operating. Note that, instead of the moving image, a still image captured every few seconds may be used, or both the moving image and the still image may be displayed on the examiner monitor unit 32.

[0059] Next, the examiner confirms the presence of the subject from the display on the examiner monitor unit 32. When the subject is present, it includes not only the case where the entire body of the subject is shown, but also the case where a part such as the head of the subject is shown. Regarding the recognition result of the presence of the subject, presence detection information or non-presence detection information is output as operation information from the main body control unit 36 to the apparatus control unit 20 by the operation input of the operation unit 31 by the examiner. The presence detection information is information indicating that the examiner has recognized the presence of the subject, so the presence of the subject has been detected (presence detected). The non-presence detection information is information indicating that the examiner has not recognized the presence of the subject, so the presence of the subject has not been detected (non-presence detected). When the presence detection information is input, the apparatus control unit 20 determines that the presence has been detected in step S3. On the other hand, when the non-presence detection information is input, the apparatus control unit 20 determines that the presence has not been detected in step S3. Note that the confirmation of the presence of the subject may be automatically performed by an artificial intelligence processing unit (Artificial Intelligence, AI) instead of the examiner. For this reason, the artificial intelligence processing unit is to be mounted on the remote operation device 30 together with an AI model or the like.

[0060] In step S4, following the determination of the presence detection in step S3, the apparatus control unit 20 executes an inspection guidance process and proceeds to step S5. The inspection guidance process will be described later with reference to the flowchart of FIG. 6.

[0061] In step S5, following the inspection guidance process in step S4, the apparatus control unit 20 executes an inspection execution process and proceeds to step S6. The inspection execution process will be described later with reference to the flowchart of FIG. 7.

[0062] In step S6, following the inspection execution process in step S5 or the determination of non-detection of evacuation in step S7, the apparatus control unit 20 executes an inspection end notification process and proceeds to step S7. The inspection end notification process is a process of notifying the subject that the inspection has ended. This process automatically inputs automatic voice information from the apparatus control unit 20 to the subject speaker 16 when proceeding to step S6, and the subject speaker 16 outputs the automatic voice information. Alternatively, end notification display information for notifying the end from the apparatus control unit 20 to the monitor unit 15 may be input, and the end notification display information may be displayed on the monitor unit 15. The automatic voice information and the end notification display information are, for example, "Please remove your face from the frame part. All inspections have been completed. Thank you for your hard work." Here, when returning to step S6 following the determination of non-detection of evacuation in step S7, the subject will be prompted to evacuate again.

[0063] In this way, when the ophthalmic examination ends (step S5), an inspection end notification process for notifying the subject that the inspection has ended is executed (step S6). That is, since the remote control device 30 exists at a remote position from the ophthalmic device 10, it is necessary to notify the subject that the inspection has ended. Therefore, by executing the inspection end notification process, it is possible to notify the subject that the inspection has ended and the subject can recognize the end of the inspection.

[0064] In step S7, following the inspection end notification process in step S6, the apparatus control unit 20 determines whether or not the subject has evacuated. If YES, it returns to step S3, and if NO, it returns to step S6. The detection of the subject's evacuation, that is, the non-detection of the subject's presence, is determined from the video of the subject camera 18. First, the subject display information of the subject camera 18 is output from the subject camera 18 to the main body control unit 36 through the apparatus control unit 20. Thereby, the main body control unit 36 displays the subject display information on the examiner monitor unit 32. The main body control unit 36 displays the subject display information on the examiner monitor unit 32 while the subject camera 18 is operating.

[0065] Next, the examiner confirms the evacuation of the subject from the display of the examiner monitor unit 32. When the subject has evacuated, it means that the whole body of the subject is not shown, excluding the case where a part of the subject's head or the like is shown. Regarding the recognition result of the subject's evacuation, depending on the operation input of the operation unit 31 by the examiner, evacuation detection information or non-evacuation detection information is output as operation information from the main body control unit 36 to the device control unit 20. The evacuation detection information is information indicating that the examiner did not recognize the presence of the subject but recognized the evacuation of the subject, that is, the evacuation of the subject was detected (evacuation detected). The non-evacuation detection information is information indicating that the examiner recognized the presence of the subject but did not recognize the evacuation of the subject, that is, the evacuation of the subject was not detected (non-evacuation detected). When the evacuation detection information is input, the device control unit 20 determines that evacuation has been detected in step S7. On the other hand, when the non-evacuation detection information is input, the device control unit 20 determines that non-evacuation has been detected in step S7. Here, if the determination of non-evacuation detection in step S7 continues, steps S6 and S7 are repeated. Note that, as described in step S3, the confirmation of the subject's evacuation may be automatically performed by an artificial intelligence processing unit (Artificial Intelligence, AI) instead of the examiner.

[0066] In step S11, following the determination of non-detection of presence in step S3, the remote operation reception unit 22 determines whether a sleep signal has been received. If YES, it proceeds to step S12; if NO, it returns to step S3. In step S11, when the ophthalmic device 10 is in the inspection mode, when a sleep signal is output from the main body control unit 36 by the operation input of the operation unit 31 of the examiner, the remote operation reception unit 22 receives the sleep signal. And the remote operation reception unit 22 determines that the sleep signal has been received. Here, if the determination of non-detection of presence in step S3 and the determination of non-reception of the sleep signal in step S11 continue, steps S3 and S11 are repeated.

[0067] In step S12, following the reception of the sleep signal in step S11, the remote operation reception unit 22 and the device control unit 20 execute the sleep mode transition process and proceed to return. Since the remote operation reception unit 22 received the sleep signal in step S11, the remote operation reception unit 22 outputs the sleep signal to the device control unit 20. As a result, the device control unit 20 controls to pause the operations of the jaw support unit 12a, the drive mechanism 13, the measurement head 14, the monitor unit 15, and the subject camera 18.

[0068] Also, when the subject speaker 16 and the subject microphone 17 are operating, the device control unit 20 controls to pause the operations of the subject speaker 16 and the subject microphone 17. Next, the device control unit 20 performs mode transition control to shift the ophthalmic device 10 from the inspection mode to the sleep mode, and controls to pause the device control unit 20. In other words, the device control unit 20 controls to turn off the power supply to all of the ophthalmic device 10 except for the communication interface 21 and the remote operation reception unit 22.

[0069] In this way, when a sleep signal is input from the remote control device 30 (YES in step S11), the device control unit 20 shifts the ophthalmic device 10 from the inspection mode to the sleep mode (step S12, return). However, the device control unit 20 makes it a condition that the subject's posture has not been detected by the subject camera 18 (NO in step S3). That is, it is not necessary for the examiner to visit the remote location for the transition from the inspection mode to the sleep mode. For this reason, when the examiner remotely operates the ophthalmic device 10 using the remote control device 30, the examiner can remotely perform the transition from the sleep mode to the inspection mode. Also, when the subject's posture has not been detected, operating the ophthalmic device 10 would result in wasted power consumption, so the examiner remotely operates to shift from the inspection mode to the sleep mode. For this reason, the power consumption of the ophthalmic device 10 can be reduced compared to the inspection mode.

[0070] Next, the flow of the inspection guidance process in step S4 is described as follows using an example of the flowchart in FIG. 6.

[0071] Steps S41 to S45 are an examination guidance process for guiding the subject to the examination (ophthalmic device 10). The device control unit 20 performs examination guidance control for this examination guidance process. For example, when proceeding to step S4, automatically, by inputting guidance display information from the device control unit 20 to the monitor unit 15, the guidance display information is displayed on the monitor unit 15 (display control). The guidance display information is information for guiding the subject to the ophthalmic device 10.

[0072] In step S41, following the start of the examination guidance process, a display for seating the subject is displayed on the monitor unit 15 by the device control unit 20, and the process proceeds to step S42.

[0073] In step S42, following the display in step S41, a display for explaining the set position of the subject's face is displayed on the monitor unit 15 by the device control unit 20, and the process proceeds to step S43.

[0074] In step S43, following the display in step S42, a display indicating the position of the subject microphone 17 is displayed on the monitor unit 15 by the device control unit 20, and the process proceeds to step S44.

[0075] In step S44, following the display in step S43, a display of precautions during the examination of the ophthalmic device 10 is displayed on the monitor unit 15 by the device control unit 20, and the process proceeds to step S45.

[0076] In step S45, following the display in step S44, a display of the start of the examination of the ophthalmic device 10 is displayed on the monitor unit 15 by the device control unit 20, and the process proceeds to the end of the examination guidance process.

[0077] Next, the flow of the examination execution process in step S5 is described as follows using an example of the flowchart in FIG. 7.

[0078] Steps S51 to S56 are an examination execution process for examining the subject eye with the ophthalmic device 10. The examination execution control of the process is performed by the device control unit 20 and the remote operation of the examiner.

[0079] In step S51, following the start of the inspection execution process, the apparatus control unit 20 executes an inspection explanation and proceeds to step S52. The execution of the inspection explanation includes an explanation of the upcoming inspection and an explanation that the subject can interact with the examiner by speaking towards the subject microphone 17 when the subject has questions or the like. When proceeding to step S51, the execution of the inspection explanation automatically causes the subject speaker 16 to output automatic voice information from the apparatus control unit 20 to the subject speaker 16. For example, "An eye refractive power inspection will be performed next. If you have any questions or the like, you can interact by speaking towards the microphone." and the like.

[0080] In step S52, following the execution of the inspection explanation in step S51, the apparatus control unit 20 performs on-control of the interactive function and proceeds to step S53. When turning on the interactive function, an on-signal for turning on the subject microphone 17 is automatically output from the main body control unit 36 to the apparatus control unit 20. Thereby, the apparatus control unit 20 performs on-control (voice control) to switch the switch of the subject microphone 17 from off to on. Until the switch of the subject microphone 17 is turned off, the subject voice input to the subject microphone 17 is output to the main body control unit 36 through the apparatus control unit 20. Thereby, since the main body control unit 36 outputs the subject voice information from the examiner speaker 33, the subject's questions or the like can be conveyed to the examiner. The interactive function is a function that enables interaction between the subject and the examiner when this function is on.

[0081] In step S53, following the on-control of the interactive function in step S52, the device control unit 20 determines whether to start the execution of the ophthalmic examination. If YES, it proceeds to step S54; if NO, it repeats step S53. The execution start signal of the ophthalmic examination is output to the device control unit 20 through the main body control unit 36 by the operation input of the operator unit 31 of the examiner. Thereby, the ophthalmic examination is actually started by the examiner. If the execution start signal of the ophthalmic examination is not output to the device control unit 20, step S53 is repeated. That is, the eye subject is in a waiting state waiting for the start of the execution of the ophthalmic examination.

[0082] In step S54, following the start of the execution of the ophthalmic examination in step S53, or following the determination of non-completion of the examination in step S55, the ophthalmic examination is actually performed by the examiner and proceeds to step S55. The execution of the ophthalmic examination is performed when the examiner speaks toward the examiner microphone 34 or when the examiner operates the operator unit 31. The examiner voice and operation information input to the examiner microphone 34 are output to the device control unit 20 through the main body control unit 36. Thereby, the device control unit 20 outputs examiner voice information from the subject speaker 16, so that the examiner can give instructions to the subject (voice control).

[0083] Also, the device control unit 20 drives and controls the drive mechanism 13 based on the operation information to adjust the Y direction of the jaw support part 12a and perform the approximate XYZ direction alignment of the auto-ref keratometer 141 with respect to the eye to be examined. In addition, the device control unit 20 performs examination execution control necessary for the ophthalmic examination based on the operation information. Further, the measurement result information of the auto-ref keratometer 141 is displayed on the monitor unit 15 from the measurement head 14 through the device control unit 20. Also, the measurement result information input to the device control unit 20 is displayed on the examiner monitor unit 32 through the main body control unit 36.

[0084] In step S55, following the execution of the ophthalmic examination in step S54, the device control unit 20 determines whether the ophthalmic examination has actually ended. If YES, it proceeds to step S56; if NO, it returns to step S54. The end of the ophthalmic examination occurs when all of the preset examination items have been completed. Therefore, the device control unit 20 determines whether all of the preset examination items have been completed based on the operation information and the measurement result information.

[0085] In this way, first, in step S52, the device control unit 20 turns on the interactive function that enables the subject and the examiner to communicate while the examination mode is on and the examination is being executed. Next, the examiner performs an ophthalmic examination using the ophthalmic device 10 (NO in steps S54 and S55 of FIG. 7). Therefore, the examiner and the subject can communicate during the examination period when the ophthalmic examination is actually being performed by the ophthalmic device 10.

[0086] In step S56, following the determination of the end of the examination in step S55, the device control unit 20 turns off the interactive function and proceeds to the end of the examination execution process. Turning off the interactive function automatically outputs an off signal from the main body control unit 36 to the device control unit 20 to switch the subject microphone 17 from on to off. As a result, the device control unit 20 performs off control (voice control) to switch the switch of the subject microphone 17 from on to off.

[0087] Next, when the interactive function is on, the execution process flow of the remote control device 30 is described as follows using an example of the flowchart in FIG. 8. The flowchart in FIG. 8 shows that when the on control of the interactive function in step S52 is executed in at least one of the three ophthalmic devices 10, a process is executed separately from FIGS. 3, 5, and FIG. 9 described later. Steps S101 to S109 are processes related to the interactive function and are performed by the remote control device 30 (main body control unit 36).

[0088] In at least one of the three ophthalmic devices 10, the device control unit 20 executes the on control of the interactive function in step S52 by outputting an on signal from the main body control unit 36. As a result, the flowchart of FIG. 8 proceeds to step S101.

[0089] In step S101, after the on control process of the interactive function in step S52 or after the return, the main body control unit 36 determines whether the interactive function is on in a plurality (two or more) of the ophthalmic devices 10. If YES, the process proceeds to step S102; if NO, the process proceeds to step S104.

[0090] The on and off controls of the interactive function of each ophthalmic device 10 are as described in steps S52 and S56 above. That is, the on and off controls of the interactive function are executed by the main body control unit 36 automatically outputting an on signal or an off signal to the device control unit 20. As described above, the main body control unit 36 stores in a memory (not shown) whether the interactive function of each ophthalmic device 10 is on, off, paused, or resumed. Therefore, the main body control unit 36 can determine whether the interactive function is on in a plurality of ophthalmic devices 10.

[0091] Also, the case of NO in step S101 is a case where the on control of the interactive function is executed by the device control unit 20 in only one of the three ophthalmic devices 10. For example, in the interactive function, the first ophthalmic device 10A is on, and the remaining second ophthalmic device 10B and third ophthalmic device 10C are off or paused. In this case, in the first ophthalmic device 10A, the on control is maintained.

[0092] In step S102, following the YES determination in step S101, the main body control unit 36 selects one ophthalmic device 10 that maintains the on state of the interactive function from among the plurality of ophthalmic devices 10 in which the interactive function is on, and the process proceeds to step S103.

[0093] For example, the main control unit 36 selects a subject who is ready for the examination from among the plurality of ophthalmic devices 10. Specifically, the selection by the main control unit 36 is determined in the order of the ophthalmic devices 10 in which the subject has entered the waiting state. In other words, the main control unit 36 selects the ophthalmic device 10 in which the interactive function has been turned on first from among the plurality of ophthalmic devices 10.

[0094] Then, when the interactive function is turned on in the plurality of ophthalmic devices 10 (on control at step S52), one ophthalmic device 10 in which the interactive function has been turned on first is selected from among the plurality of ophthalmic devices 10. The selected one ophthalmic device 10 is the ophthalmic device 10 that starts the ophthalmic examination. As described above, the order in which the interactive function is turned on is stored in the memory of the main control unit 36.

[0095] In step S103, following the selection of one ophthalmic device 10 in step S102, the main control unit 36 outputs a pause signal to the unselected ophthalmic devices 10 and proceeds to step S109. The pause signal is a signal that temporarily stops the interactive function in the ophthalmic device 10, or in other words, a signal that temporarily switches the interactive function from on to off. The output of the pause signal is executed by the main control unit 36 controlling the pause switch 327. For example, when the first ophthalmic device 10A is selected in step S102, the main control unit 36 outputs a pause signal to the remaining ophthalmic devices 10. The pause occurs before and during the ophthalmic examination. A specific example during the examination will be described later in step S107.

[0096] In step S104, following the NO determination in step S101, the main control unit 36 determines whether to output a resume signal to the ophthalmic apparatus 10 in which the interactive function is paused. If YES, the process proceeds to step S105; if NO, the process proceeds to step S109. The main control unit 36 automatically determines whether to output a resume signal to the ophthalmic apparatus 10 in which the interactive function is turned off due to the end of the ophthalmic examination of one of the ophthalmic apparatuses 10 selected in step S102. The resume signal is a signal for resuming the interactive function from a paused state to an on state in the ophthalmic apparatus 10, or in other words, a signal for switching the interactive function from an off state during pause to on again.

[0097] Moreover, the case of NO in step S104 means that in the ophthalmic apparatus 10, the on control of the interactive function continues from step S52. For example, it is the case where the on control of the interactive function continues from step S52 in the first ophthalmic apparatus 10A. In this case, in the remaining ophthalmic apparatuses 10, the off or pause of the interactive function continues.

[0098] In step S105, following the YES determination in step S104, the main control unit 36 determines whether the interactive function is paused in the plurality of ophthalmic apparatuses 10. If YES, the process proceeds to step S106; if NO, the process proceeds to step S107. As explained in step S101, the main control unit 36 can determine whether the interactive function is paused in the plurality of ophthalmic apparatuses 10. The case of YES in step S105 means, for example, that there are two remaining ophthalmic apparatuses 10 and the interactive function is paused in both of them. The case of NO in step S105 means, for example, that there are two remaining ophthalmic apparatuses 10 and the interactive function is paused in one of them.

[0099] In step S106, following the determination of YES in step S105, the main body control unit 36 selects the ophthalmic device 10 to resume the interactive function, and proceeds to step S107. For example, if there are two remaining ophthalmic devices 10 and the interactive function is suspended in both of them, the main body control unit 36 selects one of them as the ophthalmic device 10 to resume the interactive function. The selection of either one is as described in step S102, so the description is omitted.

[0100] In step S107, following the determination of NO in step S105 or the selection of the ophthalmic device 10 in step S106, the main body control unit 36 outputs an off signal or a pause signal to the ophthalmic device 10 selected in step S102, and proceeds to step S108. For example, the main body control unit 36 outputs an off signal or a pause signal to the first ophthalmic device 10A selected in step S102. The output of the off signal is executed by the main body control unit 36 controlling the function switch 326. In the case of the off signal, it means that the ophthalmic examination has ended in the first ophthalmic device 10A. In the case of the pause signal, the ophthalmic examination being performed in the first ophthalmic device 10A will be temporarily stopped. The case where the interactive function is temporarily suspended from on during the ophthalmic examination includes during the automatic examination where the first ophthalmic device 10A does not require the operator's operation, during the analysis of the examination results of the first ophthalmic device 10A, or due to interruption for the convenience of the subject, etc.

[0101] In step S108, following the output of the off signal or the pause signal in step S107, the main body control unit 36 outputs a resume signal to the ophthalmic device 10 selected in step S106 or the ophthalmic device 10 determined to have the interactive function suspended in step S105, and proceeds to step S109. The output of the resume signal is executed by the main body control unit 36 controlling the resume switch 328. The resume of the interactive function corresponds to turning on the interactive function. Therefore, the output of the on signal is executed by the main body control unit 36 controlling the function switch 326.

[0102] In step S109, following the output of the pause signal in step S103, the determination of NO in step S104, or the output of the resume signal in step S108, the main control unit 36 makes the following determination. That is, in step S109, the main control unit 36 determines whether the interactive function is off in all three ophthalmic devices 10 connected to the remote operation device 30. If YES, proceed to END; if NO, proceed to RETURN. As described in step S101, the main control unit 36 can determine whether the interactive function is off in all three ophthalmic devices 10.

[0103] Next, when the interactive function is on, the execution process flow of the ophthalmic device 10 is described as follows using an example of the flowchart in FIG. 9. The flowchart in FIG. 9 is processed by each ophthalmic device 10 separately from FIGS. 3, 5, and 8 when the on control of the interactive function in step S52 is executed in each ophthalmic device 10. Steps S201 to S206 are processes related to the interactive function and are performed by the ophthalmic device 10 (device control unit 20, remote operation reception unit 22).

[0104] In each ophthalmic device 10, the on control of the interactive function in step S52 is executed by the device control unit 20 due to the output of the on signal from the main control unit 36. As a result, the flowchart in FIG. 9 proceeds to step S201. The timing of proceeding to step S201 is the same as the timing of the flowchart in FIG. 8 proceeding to step S101. Also, even if the on control of the interactive function in step S52 is executed by the device control unit 20 in one of the three ophthalmic devices 10, the flowchart in FIG. 9 does not necessarily proceed to step S201 in all three ophthalmic devices 10. In other words, the flowchart in FIG. 9 proceeds to step S201 only in the ophthalmic device 10 in which the on control of the interactive function in step S52 is executed by the device control unit 20.

[0105] In step S201, the remote operation reception unit 22 determines whether to perform the on-control process of the interactive function in step S52 or, following a return, whether a pause signal has been received. If YES, the process proceeds to step S202; if NO, the process proceeds to step S206. When the pause signal is output from the main control unit 36, the remote operation reception unit 22 receives the pause signal. Then, the remote operation reception unit 22 determines that it has received the pause signal. If the determination that the pause signal has not been received continues in the remote operation reception unit 22, the on-control of the interactive function will continue from step S52.

[0106] In step S202, following the reception of the pause signal in step S201, the remote operation reception unit 22 and the device control unit 20 execute the process of pausing the interactive function and proceed to step S203. For the process of pausing the interactive function, first, since the remote operation reception unit 22 received the pause signal in step S201, the remote operation reception unit 22 outputs the pause signal to the device control unit 20. Next, the device control unit 20 performs off-control (voice control) to switch the switch of the subject microphone 17 from on to off upon the input of the pause signal. As a result, the interactive function is paused (during pause).

[0107] In step S203, following the pause of the interactive function in step S202, the device control unit 20 notifies the subject through the subject speaker 16 of the pause of the interactive function and proceeds to step S204. For this process, when proceeding to step S203, the subject speaker 16 outputs the automatic voice information due to the input of the automatic voice information from the device control unit 20 to the subject speaker 16. Alternatively, the function notification display information for notifying the pause of the interactive function from the device control unit 20 to the monitor unit 15 may be input, and the function notification display information may be automatically displayed on the monitor unit 15. An example of the notification in step S203 is "The conversation function is currently interrupted. Please wait a moment." Note that the "conversation function" is the interactive function.

[0108] In step S204, following the notification of the temporary stop in step S203 or the non-reception of the restart signal in step S204, the remote operation reception unit 22 determines whether a restart signal has been received. If YES, the process proceeds to step S205; if NO, step S204 is repeated. When a restart signal is output from the main body control unit 36, the remote operation reception unit 22 receives the restart signal. Then, the remote operation reception unit 22 determines that the restart signal has been received. If the determination of non-reception of the restart signal continues, the temporary stop of the interactive function will continue from step S202.

[0109] In step S205, following the reception of the restart signal in step S204, the remote operation reception unit 22 and the device control unit 20 execute the process of restarting (turning on control) the interactive function and proceed to step S206. For the process of restarting the interactive function, first, since the remote operation reception unit 22 received the restart signal in step S204, the remote operation reception unit 22 outputs the restart signal to the device control unit 20. Next, the device control unit 20 performs on control (voice control) to switch the switch of the subject microphone 17 from off to on upon the input of the restart signal. Thereby, the interactive function is turned on.

[0110] In step S206, following the non-reception of the temporary stop signal in step S201 or the restart of the interactive function in step S205, the device control unit 20 determines whether the interactive function is off in the ophthalmic device 10. If YES, the process proceeds to END; if NO, the process proceeds to RETURN. Since the device control unit 20 controls the on and off of the interactive function in the ophthalmic device 10, it stores in a memory (not shown) whether the interactive function of the ophthalmic device 10 is on or off. Therefore, the determination here can be made by the device control unit 20.

[0111] The flow of the flowcharts in FIGS. 8 and 9 will be described using the display examples of the examiner monitor unit 32 from FIGS. 11A to 11D based on an example of the time chart in FIG. 10. In FIG. 10, the horizontal axis indicates time divided for each ophthalmic device 10, and the vertical axis indicates the time (t). The text described on the right side of the vertical line at each time t in FIG. 10 simply shows the state of each ophthalmic device 10 at each time t. Hereinafter, the text in FIG. 10 will be described. "On", "Off", "Stop (temporary stop, in temporary stop)", and "Resume" indicate the state of the interactive function. Further, "Inspection" indicates that an ophthalmic examination of the subject is actually being performed, "End" indicates that the ophthalmic examination of the examiner has ended, and "Absent" indicates that the subject is not present. Furthermore, "Guidance" described in FIG. 10 indicates that the examination guidance process is being executed, "Standby" indicates that the subject is waiting in a state where the examination preparation is complete, and "Notification" indicates that the interactive function is temporarily stopped and a notification is being made to the subject. That is, for example, the text "On, Inspection" means that in the ophthalmic device 10, the interactive function is in the on state and the inspection is being performed. Also, the arrow indicates a state change from the left description to the right description of the arrow.

[0112] At time t1, the display of the examiner monitor unit 32 is, for example, in the state of FIG. 11A. At time t1, in the first ophthalmic device 10A, the interactive function is on and an ophthalmic examination is being performed. In the second ophthalmic device 10B, the subject is present and the examination guidance process is being executed. In the third ophthalmic device 10C, the subject is absent. Also, in the second ophthalmic device 10B and the third ophthalmic device 10C, the interactive function is off, and among the three ophthalmic devices 10, none of them have the interactive function temporarily stopped. The time t1 corresponds to the flow to "NO" in step S101, "NO" in step S104, and "NO" in step S109 of FIG. 8 in the processing of the main control unit 36. The time t1 corresponds to the flow from "NO" in step S201 to "NO" in step S206 of FIG. 9 in the processing of the first ophthalmic device 10A. At time t1, the interactive function is off in the second ophthalmic device 10B and the third ophthalmic device 10C. Therefore, the process shown in FIG. 9 is not executed.

[0113] At time t2, the display of the examiner monitor unit 32 is in the state shown in, for example, FIG. 11B. At time t2, the states of the first ophthalmic device 10A and the third ophthalmic device 10C are the same as those at time t1. On the other hand, the interactive function is on in the second ophthalmic device 10B. However, the interactive function of the first ophthalmic device 10A is on earlier than that of the second ophthalmic device 10B. Time t2 corresponds to the flow from step S101 “YES” to step S102 in FIG. 8 in the processing of the main control unit 36. Time t2 corresponds to the flow from step S201 “NO” to step S206 “NO” in FIG. 9 in the processing of the first ophthalmic device 10A and the second ophthalmic device 10B. At time t2, in the third ophthalmic device 10C, the processing shown in FIG. 9 is not executed as in the case of time t1.

[0114] At time t3, the state of the first ophthalmic device 10A is the same as that at time t1. Although the subject is present in the second ophthalmic device 10B, a pause signal is output from the main control unit 36. Further, the second ophthalmic device 10B determines that it has received the pause signal. Furthermore, the second ophthalmic device 10B notifies the subject through the subject speaker 16B that the interactive function has been paused. In the third ophthalmic device 10C, the subject is present and the examination guidance process is being executed.

[0115] The time t3 corresponds to the flow from step S102 to step S103 in FIG. 8 in the processing of the main control unit 36. The time t3 corresponds to the flow from step S201 “NO” to step S206 “NO” in FIG. 9 in the processing of the first ophthalmic device 10A. At the time t3, in the processing of the second ophthalmic device 10B, it corresponds to the flow of step S201 “YES”, step S202, step S203, and step S204 “NO” in FIG. 9. In the processing of the second ophthalmic device 10B, the flow of step S204 “NO” is repeated until it is determined that the second ophthalmic device 10B has received a restart signal. In the processing of the second ophthalmic device 10B, the flow of step S204 “NO” is repeated until the time t6. Therefore, the description of the processing of the second ophthalmic device 10B is omitted until the time t6. At the time t3, in the third ophthalmic device 10C, the processing shown in FIG. 9 is not executed as in the case of the time t1.

[0116] Between the time t3 and the time t4, the main control unit 36 does not output a restart signal to the temporarily stopped second ophthalmic device 10B. The period from the time t3 to the time t4 corresponds to the flow from step S103 to step S109 “NO” in FIG. 8 in the processing of the main control unit 36. The period from the time t3 to the time t4 is the same as that at the time t3 in FIG. 9 in the processing of the first ophthalmic device 10A and the third ophthalmic device 10C.

[0117] At the time t4, the state of the first ophthalmic device 10A is the same as that at the time t1. The interactive function is on in the first ophthalmic device 10A and the third ophthalmic device 10C. However, the interactive function of the first ophthalmic device 10A is turned on earlier than that of the third ophthalmic device 10C. The time t4 corresponds to the flow from step S101 “YES” to step S102 in FIG. 8 in the processing of the main control unit 36. The time t4 corresponds to the flow from step S201 “NO” to step S206 “NO” in FIG. 9 in the processing of the first ophthalmic device 10A and the third ophthalmic device 10C.

[0118] At time t5, the state of the first ophthalmic device 10A is the same as that at time t1. Although the subject exists in the third ophthalmic device 10C, a pause signal is output from the main body control unit 36. Also, the third ophthalmic device 10C determines that it has received the pause signal. Further, the third ophthalmic device 10C notifies the subject through the subject speaker 16C of the temporary suspension of the interactive function.

[0119] Time t5 corresponds to the flow from step S102 to step S103 in FIG. 8 in the process of the main body control unit 36. Time t5 corresponds to the flow from "NO" in step S201 to "NO" in step S206 in FIG. 9 in the process of the first ophthalmic device 10A. At time t5, in the process of the third ophthalmic device 10C, it corresponds to the flow of "YES" in step S201, step S202, step S203, and "NO" in step S204 in FIG. 9. In the process of the third ophthalmic device 10C, the flow of "NO" in step S204 is repeated until the third ophthalmic device 10C determines that it has received a resume signal. In the process of the third ophthalmic device 10C, the flow of "NO" in step S204 is repeated until time t8. Therefore, the description of the process of the third ophthalmic device 10C is omitted until time t8.

[0120] During the period from time t5 to time t6, the main body control unit 36 does not output a resume signal to the second ophthalmic device 10B and the third ophthalmic device 10C in which the interactive function is temporarily suspended. The period from time t5 to time t6 corresponds to the flow from step S103 to "NO" in step S109 in FIG. 8 in the process of the main body control unit 36. During the period from time t5 to time t6, in the process of the first ophthalmic device 10A, FIG. 9 is the same as at time t5.

[0121] At time t6, the display of the examiner monitor unit 32 is, for example, in the state shown in FIG. 11C. At time t6, the first ophthalmic apparatus 10A has completed the ophthalmic examination, but the interactive function is on. Also, the interactive functions of the second ophthalmic apparatus 10B and the third ophthalmic apparatus 10C are suspended. Therefore, the main control unit 36 outputs a restart signal to the second ophthalmic apparatus 10B and the third ophthalmic apparatus 10C whose interactive functions are suspended.

[0122] Furthermore, the main control unit 36 determines that the interactive functions are suspended in the plurality of ophthalmic apparatuses 10. Here, the interactive function of the second ophthalmic apparatus 10B was turned on earlier than that of the third ophthalmic apparatus 10C. Therefore, the main control unit 36 selects the second ophthalmic apparatus 10B to restart the interactive function. Next, the interactive function of the first ophthalmic apparatus 10A is on. Therefore, the main control unit 36 outputs an off signal to the first ophthalmic apparatus 10A. Subsequently, the main control unit 36 outputs a restart signal to the second ophthalmic apparatus 10B. The second ophthalmic apparatus 10B determines that it has received the restart signal. Furthermore, the second ophthalmic apparatus 10B executes the process of restarting the interactive function.

[0123] The time t6 corresponds to the flow to "NO" in step S101, "YES" in step S104, "YES" in step S105, step S106, step S107, step S108, and "NO" in step S109 of FIG. 8 in the process of the main control unit 36. The time t6 corresponds to the flow to "NO" in step S201, "YES" in step S206, and end in FIG. 9 in the process of the first ophthalmic apparatus 10A. At time t6, in the process of the second ophthalmic apparatus 10B, it corresponds to the flow to "YES" in step S204, step S205, and "NO" in step S206 of FIG. 9.

[0124] At time t7, the display of the examiner monitor unit 32 is in the state shown in, for example, FIG. 11D. At time t7, the first ophthalmic device 10A has no subject. The second ophthalmic device 10B has its interactive function turned on due to resumption, and an ophthalmic examination is being performed. Time t7 corresponds to the flow to "NO" in step S101, "NO" in step S104, and "NO" in step S109 of FIG. 8 in the processing of the main control unit 36. Since the interactive function of the first ophthalmic device 10A is off at time t7, the process shown in FIG. 9 is not executed. Also, since there is no change in the state of the first ophthalmic device 10A after time t7, the description is omitted. Time t7 corresponds to the flow from "NO" in step S201 to "NO" in step S206 of FIG. 9 in the processing of the second ophthalmic device 10B.

[0125] At time t8, the second ophthalmic device 10B finishes the ophthalmic examination, but its interactive function is on. Also, the third ophthalmic device 10C has its interactive function paused. Therefore, the main control unit 36 outputs a resume signal to the third ophthalmic device 10C whose interactive function is paused. Further, the main control unit 36 determines that the interactive functions of the plurality of ophthalmic devices 10 are not paused. Therefore, the main control unit 36 selects the third ophthalmic device 10C to resume the interactive function. Next, the interactive function of the second ophthalmic device 10B is on. Therefore, the main control unit 36 outputs an off signal to the second ophthalmic device 10B. Subsequently, the main control unit 36 outputs a resume signal to the third ophthalmic device 10C. The third ophthalmic device 10C determines that it has received the resume signal. Further, the third ophthalmic device 10C executes the process of resuming the interactive function.

[0126] The time t8 corresponds to the flow to "NO" in step S101, "YES" in step S104, "NO" in step S105, step S107, step S108, and "NO" in step S109 in FIG. 8 in the processing of the main control unit 36. The time t8 corresponds to the flow to "NO" in step S201, "YES" in step S206, and end in FIG. 9 in the processing of the second ophthalmic device 10B. At the time t8, in the processing of the third ophthalmic device 10C, it corresponds to the flow to "YES" in step S204, step S205, and "NO" in step S206 in FIG. 9.

[0127] After the time t8, the second ophthalmic device 10B has no subject. Therefore, the interactive function between the first ophthalmic device 10A and the second ophthalmic device 10B is turned off. The third ophthalmic device 10C has completed the ophthalmic examination and the interactive function is turned off. After the time t8 corresponds to the flow to "NO" in step S201, "YES" in step S206, and end in FIG. 9 in the processing of the third ophthalmic device 10C. After the time t8 corresponds to the flow from "NO" in step S101 to "NO" in step S104, "YES" in step S109, and end in FIG. 8 in the processing of the main control unit 36. Thereby, the processing of the flowcharts in FIGS. 8 and 9 is completed.

[0128] Next, the conventional technical problems will be described for the case where an examiner remotely operates an ophthalmic device using a host device through the Internet or the like.

[0129] Conventionally, in the remote operation by an examiner, not only when the examiner gives an instruction to the subject, but also the subject may want to interact with the examiner. Also, since the remote operation by the examiner is possible, it is possible to remotely operate a plurality of ophthalmic devices using a single host device. In other words, one examiner can remotely perform an ophthalmic examination on each of a plurality of subjects. For this reason, there is a problem that there may be a timing when one examiner interacts with a plurality of subjects at the same time. And when one examiner interacts with a plurality of subjects at the same time, it becomes difficult to have an appropriate interaction.

[0130] Next, the operation of the ophthalmic system 1 of Example 1 will be described as follows.

[0131] In the ophthalmic system 1 of the present disclosure, each ophthalmic device 10 has a subject microphone 17 and a subject speaker 16. The remote operation device 30 has an examiner microphone 34 and an examiner speaker 33. The ophthalmic system 1 has an interactive function that enables the subject on the side of each ophthalmic device 10 and the examiner on the side of the remote operation device 30 to communicate with each other. When the interactive function is on in two or more of the three ophthalmic devices 10 (10A and 10B, 10A and 10C, or 10B and 10C) of the remote operation device 30 (step S101 in FIG. 8), the interactive function in one ophthalmic device (10A or 10B) is maintained (step S102 etc. in FIG. 8). Further, the remote operation device 30 outputs a pause signal to the remaining ophthalmic device (10B or 10C) (step S103 in FIG. 8). That is, when the interactive function is on in two or more ophthalmic devices 10, the interactive function is maintained only for any one of the ophthalmic devices 10 (steps S102 and S103 etc. in FIG. 8). Thereby, even when a timing occurs in which one examiner communicates with a plurality of subjects simultaneously, the examiner will communicate only with the subject being examined by any one of the ophthalmic devices 10. For this reason, when an examiner remotely operates three ophthalmic devices 10 using one remote operation device 30, one examiner can individually communicate with three (plural) subjects.

[0132] When the interactive function is on in two or more ophthalmic devices 10, the remote operation device 30 of the ophthalmic system 1 of the present disclosure maintains the on state of the interactive function in one ophthalmic device 10 in which the interactive function was first turned on (step S102 etc. in FIG. 8). For this reason, since it is not necessary for the examiner to select one ophthalmic device 10 that enables communication, the selection burden on the examiner can be reduced. Further, since the waiting time for ophthalmic examination can be shortened, the processing speed of ophthalmic examination can be increased.

[0133] The remote control device 30 of the ophthalmic system 1 of the present disclosure outputs a pause signal to pause the interactive function for the remaining ophthalmic devices 10 (step S103 in FIG. 8). Therefore, the interactive functions of the remaining ophthalmic devices 10 can be surely paused.

[0134] In the ophthalmic system 1 of the present disclosure, when a pause signal is input from the remote control device 30 to each of the remaining ophthalmic devices 10 (steps S201 and S202 in FIG. 9), each of the ophthalmic devices 10 notifies the subject on its side of the pause of the interactive function (step S203 in FIG. 9). Therefore, it is possible to clearly notify each subject in the remaining ophthalmic devices 10 that interaction with the examiner is not possible. As a result, the subject can wait for the start of the ophthalmic examination with peace of mind.

[0135] When the remote control device 30 of the ophthalmic system 1 of the present disclosure gives an instruction to turn off the interactive function for one ophthalmic device 10 (outputs an off signal) (step S107 in FIG. 8), it gives an instruction to resume from the pause of the interactive function to one of the remaining ophthalmic devices 10 (outputs a resume signal. (step S108 in FIG. 8)). That is, instead of one ophthalmic device 10, the interactive function can be resumed by turning it on for one of the remaining ophthalmic devices 10. Therefore, the interactive function can be surely turned on for only one of the remaining ophthalmic devices 10.

[0136] The remote control device 30 of the ophthalmic system 1 of the present disclosure has a pause switch 327 that outputs a pause signal and a resume switch 328 that outputs a resume signal for each ophthalmic device 10. That is, the remote control device 30 can output either signal to the ophthalmic device 10 by selection. Therefore, the remote control device 30 can automatically output a signal by operating the pause switch 327 and the resume switch 328.

[0137] The ophthalmic system 1 of the present disclosure has been described based on Example 1 above. However, the specific configuration is not limited to Example 1, and design changes, additions, etc. are allowed as long as they do not deviate from the gist of the invention according to each claim of the claims.

[0138] In step S102 of the above Example 1, an example was shown in which the selection of the main body control unit 36 is determined in the order of the ophthalmic devices 10 when the subject is waiting, but it is not limited to this. For example, the selection of the main body control unit 36 may be determined as one ophthalmic device 10 that first starts a dialogue using the interactive function among a plurality of ophthalmic devices 10. Specifically, when the interactive functions of three ophthalmic devices 10 are on, subject voice information is input from the plurality of ophthalmic devices 10 to the main body control unit 36. The main body control unit 36 automatically selects one ophthalmic device 10 from among the plurality of ophthalmic devices 10 where the subject voice information was first input. In other words, the main body control unit 36 selects one ophthalmic device 10 based on the subject voice information input from the plurality of ophthalmic devices 10. Therefore, since the dialogue has been started first, it is possible to preferentially maintain the activation of the interactive function without interrupting the dialogue. Furthermore, since it is not necessary to select one ophthalmic device 10 that enables the examiner to have a dialogue, the selection burden on the examiner can be reduced.

[0139] Alternatively, instead of the selection by the system control unit 36, the examiner may make the selection. The examiner's selection involves the examiner ranking the plurality of ophthalmic devices 10 and determining one ophthalmic device 10. The ranking may prioritize, for example, subjects with high urgency such as emergency patients, subjects whose condition indicates a higher need for an ophthalmic examination than other subjects, or subjects such as children or the elderly who may have difficulty waiting until the start of the ophthalmic examination. For the remaining ophthalmic devices 10 not selected by the examiner, the "temporary stop switch 327" shown in FIGS. 11A to 11D is selected, and the interactive function in the remaining ophthalmic devices 10 switches from on to temporarily stopped. As a result, the interactive function remains on in one ophthalmic device 10. Therefore, for example, when there are subjects with high urgency such as emergency patients, the examiner's selection can preferentially maintain the on state of the interactive function. In the case of the examiner's selection, the switching of the interactive function between on, off, temporary stop, and restart is performed by the examiner selecting the function switch 326, the temporary stop switch 327, and the restart switch 328.

[0140] At time t6 in the above-described Example 1, the main control unit 36 was shown to output an off signal to the first ophthalmic device 10A. Also, at time t6, in the process of the first ophthalmic device 10A, an example corresponding to "NO" in step S201, "YES" in step S206, and the flow to end in FIG. 9 was shown. However, it is not limited to this. For example, if the ophthalmic examination in the first ophthalmic device 10A has not been completed, the interactive function may be temporarily stopped. For this reason, at time t6, the main control unit 36 outputs a pause signal to the first ophthalmic device 10A. Also, at time t6, in the process of the first ophthalmic device 10A, it corresponds to "NO" in step S201, "NO" in step S206, and the flow to return in FIG. 9. And then, the interactive function can be resumed in the first ophthalmic device 10A. In this way, even during the examination, the interactive function can be temporarily stopped from being on. That is, as described above, for the temporary stop, there may be a case where the first ophthalmic device 10A is in an automatic inspection that does not require the operator's operation. For this reason, even during the ophthalmic examination, the interactive function can be temporarily stopped from being on. In other words, even if the interactive function is temporarily stopped from being on, the ophthalmic examination can be continued.

[0141] In the examiner monitor unit 32 of the above-described Example 1, an example in which the function switch 326, the pause switch 327, and the resume switch 328 are displayed was shown, but it is not limited to this. For example, without displaying the resume switch 328, when the pause switch 327 is displayed in black characters on a white background, the pause switch 327 is selected. Thereby, it may be set such that the interactive function can be switched from being paused to being resumed. In short, it is not limited to the types and numbers of those switches, and any configuration that can switch the on, off, pause, and resume of the interactive function is acceptable.

[0142] In step S52 of the above-described Example 1, an example was shown in which, following the execution of the inspection explanation in step S51, the interactive function is turned on, but it is not limited to this. For example, the timing of turning on the interactive function may be performed following the determination of subject detection in step S3, or may be performed during the inspection guidance process in step S4. Alternatively, it may be performed during the inspection execution process in step S5 and before the execution of the inspection explanation in step S51. Thereby, prior to step S52, a request from the subject to the examiner can be conveyed. For example, the request may be "I want to go to the toilet, so please wait a little." Also, even if the interactive function is turned on at any timing, the processes of FIGS. 8 and 9 are executed.

[0143] In the above-described Example 1, an example was shown in which the lens used for the subject camera 18 is not particularly limited, but the lens is preferably a wide-angle lens, and more preferably a fish-eye lens. Further, rather than a lens, the subject camera 18 is more preferably a 360-degree camera. By using a wide-angle lens for the subject camera 18 or a 360-degree camera, it is possible to photograph a wider range around the ophthalmic device 10 than when using other lenses or the like. That is, the subject camera 18 can photograph not only the subject in the inspection posture but also a subject existing in the X direction of the ophthalmic device 10 (around the ophthalmic device 10 in the case of a 360-degree camera). For this reason, the speed of detecting and determining the presence in step S3 is increased, and it is possible to shorten the time until the start of the ophthalmic examination.

[0144] In step S4 etc. of the above-described Example 1, an example was shown in which the processing is automatically executed by the apparatus control unit 20 or the main body control unit 36, but it is not limited to this. The part that is automatically processed may not be automatic, and the processing may be executed as appropriate by the remote operation of the examiner or the voice of the examiner. Also, the ophthalmic device 10 in which the interactive function is turned off or temporarily stopped may be set so as not to be operated automatically or manually by the main body control unit 36. Thereby, the ophthalmic device 10 in which the interactive function is turned off or temporarily stopped can prevent the possibility of being accidentally operated.

[0145] In the above-described Example 1, an example was shown in which the communication interface 21 and the main body control unit 36 perform input / output of various types of information with each other via the router 100 and the Internet 101. However, the present invention is not limited to this. In short, the communication network that connects the communication interface 21 and the main body control unit 36 only needs to be able to perform input / output of various types of information with each other and to enable remote operation by the examiner.

[0146] In the above-described ophthalmic system 1 of Example 1, as shown in FIG. 1 and the like, an example was shown in which three ophthalmic devices 10 and one remote operation device 30 are provided. However, the present invention is not limited to this. Since the number of ophthalmic devices 10 may be plural, the ophthalmic system 1 may include two or four or more ophthalmic devices 10. Further, the plurality of ophthalmic devices 10 in steps S101 and S105 of FIG. 8 are not limited to two, and when there are four or more ophthalmic devices 10 in the ophthalmic system 1, the number may be three or more. Even in this case, it is possible to select one ophthalmic device 10 in steps S102 and S106 of FIG. 8.
