Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the ophthalmic device and the host device are located remotely. For this reason, there is a problem that the subject is unaware of whether the ophthalmic device is connected to the host device or not only by the voice of the examiner being notified to the subject through the speaker.

[0005] The present disclosure has been made paying attention to the above problems, and an object thereof is to provide an ophthalmic system capable of clearly showing to the subject that the ophthalmic device is connected to the host device when the examiner remotely operates the ophthalmic device using the host device.

Means for Solving the Problems

[0006] The ophthalmic system of the present disclosure includes an ophthalmic device and a host device located at a position remote from the ophthalmic device. In the ophthalmic system, the ophthalmic device and the host device can communicate with each other, and an examiner operates the ophthalmic device remotely using the host device. The ophthalmic device has a control unit, a subject camera or a human presence sensor, and a display unit. When a wake signal is input while the ophthalmic device on the subject side is in the sleep mode where the operation is paused, the control unit shifts the ophthalmic device to an inspectable inspection mode. The subject camera is provided at least at a position where the subject in the inspection posture is reflected. The human presence sensor senses whether a subject is present in the space on the front side of the ophthalmic device. An image is displayed on the display unit. After shifting to the inspection mode, the control unit displays an examiner image related to the examiner on the display unit on the condition that the presence of the subject is detected based on information from the subject camera or the human presence sensor.

Embodiments for Carrying Out the Invention

[0009] The embodiments 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 rearward direction moving away from the subject. The X direction is the left - right direction perpendicular to both the vertical direction and the front - rear direction.

Examples

[0010] The ophthalmic system 1 applied to Example 1 will be described with reference to FIG. 1. As shown in FIG. 1, the ophthalmic system 1 includes one ophthalmic device 10 and one remote control device 30 (host device). The remote control device 30 is located at a position remote from the ophthalmic device 10. In other words, the ophthalmic device 10 and the remote control device 30 are located at positions (places) separated from each other. For example, the ophthalmic device 10 and the remote control device 30 are respectively arranged in adjacent rooms. Or, the remote control device 30 is arranged in the hospital to which the examiner belongs, and the ophthalmic device 10 is arranged at a remote location away from the hospital. Therefore, the examiner is at the place where the remote control device 30 is arranged, and the subject is at the place where the ophthalmic device 10 is arranged.

[0011] The remote control device 30 is connected to a communication network such as the Internet 101 via a router 100 (router device). The remote control device 30 is connected to the ophthalmic device 10 via the Internet 101. Thereby, remote operation by the examiner is possible.

[0012] The ophthalmic device 10 is arranged on the examination table 200 for ophthalmoscopy and is used for examining the subject's eye. The ophthalmic device 10 is a composite device capable of measuring the intraocular pressure value, refractive power, corneal curvature, etc. of the subject's eye. 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 subject's eye. 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).

[0013] 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.

[0014] The face support unit 12 supports the face of the subject. The face support unit 12 is disposed in front of the drive mechanism 13. The face support unit 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 places the chin on the chin support portion 12a and abuts the forehead against the forehead abutment portion 12b to undergo an examination.

[0015] The drive mechanism 13 corresponds to a 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 chin support 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 chin support portion 12a can be adjusted, and alignment of the measurement head 14 in the XYZ directions with respect to the eye to be examined becomes possible.

[0016] Inside the measurement head 14, an optical system for known observation and photography is provided. By the optical system, various eye characteristics of the subject can be observed and photographed. Specifically, the measurement head 14 is provided with a plurality of types of various ophthalmic measuring devices including an auto refractometer 14A and the like. The auto refractometer 14A measures the eye refractive power, corneal curvature, etc. of the eye to be examined using various optical systems. Since the specific configuration of the auto refractometer 14A is a known technique, the description thereof is omitted here.

[0017] 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 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 orientation of the monitor unit 15 faces forward of the ophthalmic device 10. Further, the orientation of the monitor unit 15 is such that the subject can visually observe the display of the monitor unit 15 both when the subject stands and sits in front of the ophthalmic device 10.

[0018] The monitor unit 15 is, for example, a touch panel 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 device 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. Thereby, the subject can directly operate the ophthalmic device 10 by himself / herself.

[0019] The subject speakers 16 are built into each of the pair of frames 12c. The position of each of the subject speakers 16 is disposed near the left and right ears of the subject during eye examination of the subject.

[0020] The subject microphone 17 is built into the central portion of the base 12d, in front of and below the chin rest 12a. The position of the subject microphone 17 is disposed near the mouth of the subject during eye examination of the subject.

[0021] 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 unit 12. In addition to this, the subject camera 18 is for peripheral photographing that can photograph 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 unit 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 does not appear on the front side of the face support unit 12.

[0022] Here, the examination postures include the posture of the subject sitting on a chair or the like (not shown) provided in front of the ophthalmic apparatus 10, the posture of the subject placing the chin on the chin receiving part 12a and the forehead on the forehead abutting part 12b, and the posture of the subject standing on the front side of the face support unit 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 examination by the display on the examiner monitor unit 32. Also, the examiner can use the display on the examiner monitor unit 32 for position adjustment between the ophthalmic apparatus 10 and the subject.

[0023] Next, the control system of the ophthalmic system 1 will be described as follows with reference to FIG. 2.

[0024] In addition to the above configuration, the ophthalmic apparatus 10 includes an apparatus control unit 20, a communication interface 21, and a remote operation reception unit 22.

[0025] 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.

[0026] 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 (such as control signals) to 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.

[0027] Since the ophthalmic device 10 is remotely operated by an examiner, the remote operation device 30 will be described first.

[0028] 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.

[0029] For the operation unit 31, for example, a keyboard and a mouse are used. The operation unit 31 receives operation information for remotely operating the ophthalmic device 10 by an examiner. The operation unit 31 outputs the input operation information to the main body control unit 36.

[0030] For the examiner monitor unit 32, for example, a liquid crystal display is used. 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, etc.

[0031] For the examiner speaker 33 and the examiner microphone 34, for example, a headset (headphone with a microphone) is used. 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.

[0032] 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 at 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 based on the display of the monitor unit 15. In addition, the examiner can confirm the display state of the examiner display information on the monitor unit 15 based on the display of the examiner monitor unit 32. Here, "when the examiner is at a position where the remote control device 30 can be operated" includes during the remote operation of the examiner.

[0033] 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 [such as 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 may be realized by a plurality of processors of the same type or different types.

[0034] The main control unit 36 outputs operation information, examiner voice information, examiner display information, etc. to the communication interface 21. Further, 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 the 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 operation 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. Further, the main control unit 36 outputs operation information, etc. to the device control unit 20 based on the operation information, etc. input from the operation unit 31.

[0035] Next, the ophthalmic device 10 will be described.

[0036] 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. Further, display information, subject voice information, etc. are input to the communication interface 21 from the device control unit 20. The communication interface 21 outputs the display information, subject voice information, 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 sleep mode, which will be described later.

[0037] 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 the 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.

[0038] Similar to the above-described main body control unit 36, the device control unit 20 includes an arithmetic circuit composed of various processors, memories, and the like. Note that various controls (functions) of the device control unit 20 may be realized by a single processor or may be realized by a plurality of processors of the same type or different types.

[0039] Based on 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. Further, 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 body control unit 36. The device control unit 20 functions as mode transition control, inspection guidance control, inspection execution control, display control, voice control, etc.

[0040] 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. Further, 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.

[0041] Here, the sleep mode is a mode in which, among the ophthalmic device 10, a member that pauses a part of the operation 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 is in a state of pausing operation and waiting for a signal for starting, that is, a paused state (standby state). Further, since a part of the operation of the ophthalmic device 10 is 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 (operating state) in which inspection is possible with the ophthalmic device 10.

[0042] Next, the processing flow of the ophthalmic apparatus 10 will be described as follows using an example of the flowcharts from FIG. 3 to FIG. 5. In the flowcharts from FIG. 3 to FIG. 5, various types of information output from the main body control unit 36 are input to the apparatus control unit 20 via the communication interface 21 and the remote operation reception unit 22. Therefore, in the description of the flowchart, the description of "via the communication interface 21" or "via the communication interface 21 and the remote operation reception unit 22" may be omitted. Conversely, various types of information output from the apparatus control unit 20 are input to the main body control unit 36 via the communication interface 21. Therefore, the description of "via the communication interface 21" may be omitted.

[0043] First, the processing flow of the ophthalmic apparatus 10 will be described as follows using an example of the flowchart in FIG. 3. Until the start of the remote operation by the examiner, the ophthalmic apparatus 10 is in the sleep mode, so the program starts the processing flow in the sleep mode. "Until the start of the remote operation by the examiner" is, for example, until the start of the examination at the hospital or the like.

[0044] In the sleep mode of the ophthalmic apparatus 10 according to the first embodiment, 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 apparatus 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 apparatus 10.

[0045] 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.

[0046] 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. Thereby, the device control unit 20 is activated (operates) by the input of the wake signal. Next, the device control unit 20 performs control to activate the jaw support part 12a, the drive mechanism 13, the measurement head 14, the monitor part 15, the subject speaker 16, and the subject camera 18. In other words, the device control unit 20 performs control to turn on the power supply to all of the ophthalmic device 10.

[0047] Also, even when a wake signal is input, the device control unit 20 does not perform control to activate the subject microphone 17. Next, mode transition control for transitioning the ophthalmic device 10 from the sleep mode to the inspection mode is performed. Note that after performing the mode transition control for transitioning the ophthalmic device 10 from the sleep mode to the inspection mode, the device control unit 20 may perform control to activate the ophthalmic device 10 (such as the jaw support part 12a) during operation suspension.

[0048] In step S3, following the inspection mode transition process in step S2, the determination of the save detection in step S7, or the determination of the non-reception of the sleep signal in step S11, the device control unit 20 determines whether the device has detected the subject's posture. If YES, it proceeds to step S4; if NO, it proceeds to step S11. The detection of the subject's posture, that is, the detection of the subject's presence, 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 device 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.

[0049] 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 of the subject, such as the head, is shown. Regarding the recognition result of the subject's presence, presence detection information or non-presence detection information is output as operation information from the main body control unit 36 to the device control unit 20 by the examiner's operation input on the operation unit 31. Presence detection information is information indicating that the examiner has recognized the presence of the subject, that is, the subject's presence has been detected (presence detected). Non-presence detection information is information indicating that the examiner has not recognized the presence of the subject, that is, the subject's presence has not been detected (non-presence detected). When the presence detection information is input, the device 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 device control unit 20 determines that the presence has not been detected in step S3.

[0050] In step S4, following the determination of the presence detection in step S3, the device control unit 20 executes the inspection guidance process and proceeds to step S5. The inspection guidance process will be described later using the flowchart of FIG. 4.

[0051] In step S5, following the inspection guidance process in step S4, the device control unit 20 executes the inspection execution process and proceeds to step S6. The inspection execution process will be described later using the flowchart of FIG. 5.

[0052] 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 ended. 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.

[0053] In this way, when the ophthalmic examination ends, an inspection end notification process for notifying the subject that the inspection has ended is executed (steps S5, 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.

[0054] 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.

[0055] Next, the examiner checks from the display of the examiner monitor unit 32 whether the subject has evacuated. When it is confirmed that 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, 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 by the operation input of the operation unit 31 by the examiner. Evacuation detection information is information indicating that the examiner has detected the evacuation of the subject because the examiner did not recognize the presence of the subject but recognized the evacuation of the subject (evacuation detected). Non-evacuation detection information is information indicating that the examiner has not detected the evacuation of the subject because the examiner recognized the presence of the subject but did not recognize the evacuation of the subject (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, when the determination of non-evacuation detection in step S7 continues, steps S6 and S7 are repeated.

[0056] 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, the process proceeds to step S12; if NO, the process returns to step S3. In step S11, when the ophthalmic device 10 is in the inspection mode, if 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. Then, the remote operation reception unit 22 determines that the sleep signal has been received. Here, when 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.

[0057] 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.

[0058] 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.

[0059] 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, there is no need 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.

[0060] Next, the flow of the inspection guidance process in step S4 is described as follows using an example of the flowchart in FIG. 4 and the display examples in FIGS. 5A to 5E.

[0061] Steps S41 to S45 are inspection guidance processes for guiding the subject to the inspection (ophthalmic device 10). The device control unit 20 performs inspection guidance control for this inspection guidance process. For example, when proceeding to step S4, automatically, due to the input of 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, and for example, it is an inspection guidance image (42a, 43a, 45a) for inspection guidance for the inspection guidance process. Thereafter, the processes after step S41 are executed.

[0062] In step S41, following the start of the inspection guidance process, a display for seating the subject by the device control unit 20 is displayed on the monitor unit 15, and the process proceeds to step S42. An example of the display in step S41 is only the character image 41b (characters, display information) as shown in FIG. 5A. The character image 41b displayed in step S41 is "The inspection will start soon. Please take a seat on the chair." Note that the chair is not shown in FIG. 1.

[0063] In step S42, following the display in step S41, a display for explaining the set position of the subject's face by the device control unit 20 is displayed on the monitor unit 15, and the process proceeds to step S43. An example of the display in step S42 is a partial enlarged image (inspection guidance image 42a) in front of the ophthalmic device 10 and a character image 42b (characters, display information) as shown in FIG. 5B. The character image 42b displayed in step S42 is "Place your chin on the (A) chin rest. Place your forehead on the (B) forehead rest." Note that the "chin rest" in the display to the subject is the chin rest portion 12a. Also, the "forehead rest" in the display to the subject is the forehead rest portion 12b.

[0064] 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 apparatus control unit 20, and the process proceeds to step S44. An example of the display in step S43 is, as shown in FIG. 5C, a partially enlarged image (examination guidance image 43a) in front of the ophthalmic apparatus 10 and a character image 43b (characters, display information). The character image 43b displayed in step S43 is "During the examination, you can talk to the examiner using the microphone. The microphone is at the position of (C).". Note that the "examiner" in the display to the subject is the examiner. Also, the "microphone" in the display to the subject is the subject microphone 17.

[0065] In step S44, following the display in step S43, a display of precautions during the examination of the ophthalmic apparatus 10 is displayed on the monitor unit 15 by the apparatus control unit 20, and the process proceeds to step S45. An example of the display in step S44 is, as shown in FIG. 5D, only a character image 44b (characters, display information). First, the character image 44b displayed in step S44 is "During the examination, please do not move your face. The examiner will appear soon.". Further, the character image 44b is "Waiting" surrounded by a square frame in the upper right of the monitor unit 15. Note that the "examiner" in the display to the subject is the examiner.

[0066] In step S45, following the display in step S44, a display indicating the start of the examination of the ophthalmic apparatus 10 is displayed on the monitor unit 15 by the apparatus control unit 20, and the process proceeds to step S46. An example of the display in step S45 is, as shown in FIG. 5E, an examiner image 40 related to the examiner (a kind of examination guidance image, examination guidance image 45a, which may be omitted in the following description) and a character image 45b (characters, display information). The examiner image 40 displayed in step S45 is the examiner display information of the examiner camera 35, that is, the actual appearance of the examiner. Also, the character image 45b displayed in step S45 is "Examination start".

[0067] Here, the examiner display information of the examiner camera 35 is output from the examiner camera 35 to the apparatus control unit 20 through the main body control unit 36. Next, the apparatus control unit 20 displays the examiner display information on the monitor unit 15. That is, the apparatus control unit 20 displays the actual appearance of the examiner on the monitor unit 15. The apparatus control unit 20 displays the examiner display information on the monitor unit 15 (display control) while both the apparatus control unit 20 and the examiner camera 35 are operating. For example, the display of the examiner is displayed on the monitor unit 15 until the determination of the end of the inspection in step S54 described later.

[0068] Also, in the process of step S45, since the examiner appears, in order to start the ophthalmic examination, the examiner instructs the subject by speaking toward the examiner microphone 34. The instruction content is, for example, "Then, since the examination will start, please set your face." and the like. Subsequently, the subject sets his / her face on the face support unit 12 according to the examiner's instruction.

[0069] Here, if the actual appearance of the examiner is not displayed on the monitor unit 15, only the voice of the examiner will be heard by the subject, which may give the subject a sense of discomfort. However, by displaying the actual appearance of the examiner on the monitor unit 15, it is possible to reduce or eliminate the possibility of giving the subject a sense of discomfort by not allowing only the voice of the examiner to be heard by the subject.

[0070] In step S46, following the display in step S45 or the face setting instruction in step S48, the apparatus control unit 20 determines whether the subject has set his / her face. If YES, it proceeds to step S47, and if NO, it proceeds to step S48. In this process, the examiner confirms whether the subject has set his / her face on the face support unit 12 in the process of step S45. The reason for the confirmation is to smoothly execute the inspection execution process in step S5. The confirmation method is as follows.

[0071] During the operation of the subject camera 18, the main control unit 36 displays subject display information on the examiner monitor unit 32. In addition, the subject camera 18 can capture an image of the subject in the examination posture. That is, the subject camera 18 can capture an image of the subject with the subject's chin placed on the chin support portion 12a and the forehead in contact with the forehead rest portion 12b. Therefore, it is possible for the examiner to confirm from the display on the examiner monitor unit 32 whether the subject has set his or her face on the face support portion 12.

[0072] Regarding the confirmation result of whether the subject has set his or her face, based on the operation input of the operation unit 31 by the examiner, the main control unit 36 outputs set detection information (signal) or set non-detection information (signal) as operation information to the apparatus control unit 20. The set detection information is information indicating that the examiner has confirmed the setting of the subject's face, that is, the setting of the subject's face has been detected (set detected). The set non-detection information is information indicating that the examiner has not confirmed the setting of the subject's face, that is, the setting of the subject's face has not been detected (set not detected). When the set detection information is input, the apparatus control unit 20 determines that it is set detected in step S46.

[0073] On the other hand, when the set non-detection information is input, the apparatus control unit 20 determines that it is set not detected in step S46. Here, when proceeding to step S48 following the determination of set not detected in step S46, the examiner will be prompted again to set the face to the subject.

[0074] In step S47, following the determination of set detected in step S46, the apparatus control unit 20 executes notification switching processing during the ophthalmic examination. That is, the apparatus control unit 20 switches the notification to the subject to only the sound output from the subject speaker 16. The sound output from the subject speaker 16 is either automatic voice information or examiner voice information. However, even when notifying the subject only by the sound output from the subject speaker 16, the display on the monitor unit 15 is maintained. Thereafter, the apparatus control unit 20 proceeds to the end of the examination guidance process and returns to the flowchart of FIG. 3.

[0075] In step S48, following the determination of non-detection of setting in step S46, the examiner again instructs the subject to set the face and returns to step S46. That is, again, the examiner prompts the subject to set the face on the face support portion 12. The prompting of the subject is such that, by the operation input of the operation unit 31 of the examiner, automatic voice information from the apparatus control unit 20 is input to the subject speaker 16, and the subject speaker 16 outputs the automatic voice information. Alternatively, the examiner may prompt the subject by speaking (examiner voice information) toward the examiner microphone 34. Here, if the determination of non-detection of setting in step S46 continues, steps S46 and S48 are repeated.

[0076] Next, the flow of the inspection execution process in step S5 is described as follows using an example of the flowchart in FIG. 5.

[0077] Steps S51 to S55 are inspection execution processes for performing an inspection on the subject eye by the ophthalmic apparatus 10. The inspection execution control of the process is performed by the apparatus control unit 20 and the remote operation of the examiner.

[0078] 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 is an explanation to the effect that an inspection will be performed, and an explanation that the subject can interact with the examiner by speaking toward the subject microphone 17 when the subject has a question or the like. The execution of the inspection explanation is such that, when proceeding to step S51, automatically, by the input of automatic voice information from the apparatus control unit 20 to the subject speaker 16, the subject speaker 16 outputs the automatic voice information. For example, "An eye refractive power inspection will be performed from now on. If you have any questions or the like, you can interact by speaking toward the microphone." and the like.

[0079] In step S52, following the execution of the inspection explanation in step S51, the device control unit 20 performs on-control of the interactive function and proceeds to step S53. When the interactive function is turned on, an on-signal for turning on the subject microphone 17 is output to the device control unit 20 through the main body control unit 36 by an operation input of the operator unit 31 of the examiner. Thereby, the device control unit 20 performs on-control (voice control) to turn on the switch of the subject microphone 17. 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 device control unit 20. Thereby, since the main body control unit 36 outputs subject voice information from the examiner speaker 33, it is possible to convey a subject's question or the like to the examiner. The interactive function is a function that enables interaction between the subject and the examiner when this function is on.

[0080] Here, "until the examiner starts the inspection using the ophthalmic device 10" refers to up to the processing step immediately before "execution of the ophthalmic examination (step S53)". In the first embodiment, it is up to the on-control of the interactive function in step S52, that is, up to the processing of step S52. Further, "the examination that the examiner performs using the ophthalmic device 10" refers to "an examination (ophthalmic examination, medical examination, ophthalmic medical examination, eye examination) that the examiner remotely operates the ophthalmic device 10 using the remote operation device 30". Hereinafter, "the examination that the examiner performs using the ophthalmic device 10" may be described as "the ophthalmic examination that the examiner performs using the ophthalmic device 10".

[0081] In step S53, following the on-control of the interactive function in step S52 or the determination of non-completion of the examination in step S54, the examiner actually performs an ophthalmic examination and proceeds to step S54. The execution of the ophthalmic examination is performed by the examiner speaking toward the examiner microphone 34 or the examiner operating the operator unit 31 for operation input. 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, since the device control unit 20 outputs examiner voice information from the subject speaker 16, the examiner can give an instruction to the subject (voice control).

[0082] Further, the device control unit 20 drives and controls the drive mechanism 13 based on the operation information to adjust the jaw receiving portion 12a in the Y direction and perform a rough XYZ alignment of the auto refractometer 14A with respect to the eye to be examined. In addition, the device control unit 20 performs inspection execution control necessary for ophthalmic examinations based on the operation information. Further, the measurement result information of the auto refractometer 14A is displayed on the monitor unit 15 from the measurement head 14 through the device control unit 20. Further, 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.

[0083] In step S54, following the execution of the ophthalmic examination in step S53, the device control unit 20 determines whether the ophthalmic examination has actually ended. If YES, it proceeds to step S55; if NO, it returns to step S53. 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.

[0084] Thus, 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 in progress and the examination is being executed. Next, the examiner performs an ophthalmic examination using the ophthalmic device 10 (NO in steps S53 and S54 of FIG. 5). 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.

[0085] In step S55, following the determination of the end of the examination in step S54, the device control unit 20 performs off control of the interactive function and proceeds to the end of the examination execution process. The off of the interactive function is such that an off signal for switching the subject microphone 17 from on to off is output to the device control unit 20 through the main body control unit 36 by an operation input of the examiner's operation unit 31. Thereby, the device control unit 20 performs off control (voice control) to turn off the switch of the subject microphone 17.

[0086] As described above, when the ophthalmic examination is completed, the apparatus control unit 20 switches the interactive function from on to off (step S55 in FIG. 6). For example, if the interactive function remains on after the ophthalmic examination is completed, the sound on the subject side input to the subject microphone 17 may be output from the examiner speaker 33, which may give the examiner an uncomfortable feeling. In addition, since the interaction between the examiner and the subject becomes unnecessary after the ophthalmic examination is completed, there is no need to keep the interactive function on. As a result, after the ophthalmic examination is completed, by switching the interactive function from on to off, the sound on the subject side is no longer output from the examiner speaker 33. Therefore, it is possible to prevent the uncomfortable feeling given to the examiner. Here, the sound on the subject side is the subject's voice and the ambient sound on the subject side. The ambient sound is the sound around the ophthalmic apparatus 10, such as the sound of the subject walking or the sound of peripheral devices. Thereafter, the apparatus control unit 20 proceeds to the end of the examination execution process and returns to the flowchart of FIG. 3.

[0087] Next, the conventional technical problems will be described for the case where the examiner remotely operates the ophthalmic apparatus using the host apparatus via the Internet or the like.

[0088] Conventionally, although the examiner can remotely operate the apparatus, there is a first problem that the examiner needs to visit a remote location to shift the mode of the ophthalmic apparatus because the examiner cannot shift the mode between the examination mode and the sleep mode.

[0089] In addition, the ophthalmic apparatus and the host apparatus are located remotely. For this reason, there is a second problem that the subject is unaware of whether the ophthalmic apparatus is connected to the host apparatus, that is, whether the examiner is connected, only by the examiner's voice being notified to the subject through the speaker. In particular, when there is no notification from the examiner to the subject, nothing is output from the speaker, so the subject is unaware of whether the ophthalmic apparatus is connected to the host apparatus. Furthermore, if there is no person in charge, such as an assistant of the examiner, at the installation location of the ophthalmic apparatus, the subject cannot confirm with the person in charge whether the ophthalmic apparatus is connected to the host apparatus. In this case, the subject may undergo the ophthalmic examination while feeling worried (feeling anxious).

[0090] Next, the operation of the ophthalmic system 1 of Example 1 will be described as follows.

[0091] Regarding the first technical problem described above, the ophthalmic device 10 of the ophthalmic system 1 of the present disclosure has a device control unit 20. As shown in FIG. 3, when the ophthalmic device 10 on the subject side is in the sleep mode, a wake signal is input from the remote control device 30 on the examiner side to the device control unit 20 (start, step S1). When a wake signal is input from the remote control device 30, the device control unit 20 shifts the ophthalmic device 10 to the inspection mode (from step S1 to S2). That is, it is not necessary for the examiner to visit a remote location for the transition from the sleep mode to the inspection mode. Therefore, 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.

[0092] Regarding the second technical problem, the ophthalmic device 10 of the ophthalmic system 1 of the present disclosure has a device control unit 20, a subject camera 18, and a monitor unit 15. After shifting to the inspection mode (step S2 in FIG. 3), the device control unit 20 displays the examiner image 40 on the monitor unit 15 until the start of the ophthalmic examination using the ophthalmic device 10 by the examiner. However, the device control unit 20 makes it a condition that the presence of the subject is detected based on the subject display information from the subject camera 18 (YES in step S3 of FIG. 3). That is, on the condition that the subject is present, the presence of the examiner is clearly shown to the subject. Therefore, it can be clearly shown to the subject that the ophthalmic device 10 is connected to the remote control device 30. As a result, even when the subject cannot confirm with the person in charge whether the ophthalmic device 10 is connected to the remote control device 30, the subject can undergo the ophthalmic examination with peace of mind.

[0093] The remote control device 30 of the ophthalmic system 1 of the present disclosure has an examiner camera 35. The remote control device 30 outputs examiner display information captured by the examiner camera 35 to the device control unit 20. The device control unit 20 displays the examiner display information input from the remote control device 30 on the monitor unit 15 as an examiner image 40. That is, until the start of the ophthalmic examination, the examiner image 40, which is the actual appearance of the examiner, is displayed on the monitor unit 15. Therefore, the subject can undergo the ophthalmic examination with more peace of mind.

[0094] In the ophthalmic device 10 of the ophthalmic system 1 of the present disclosure, after the presence of the subject is detected (YES in step S3 of FIG. 3), until the start of the ophthalmic examination using the ophthalmic device 10 by the examiner (step S53 of FIG. 6), the device control unit 20 executes an examination guidance process (step S4 of FIG. 3, steps S41 to S45 of FIG. 4). In the first embodiment, the execution of the examination guidance process is before the start of the ophthalmic examination (step S5 of FIG. 3, step S53 of FIG. 6).

[0095] Here, since the remote control device 30 is located at a remote position from the ophthalmic device 10, in order to start the examination of the subject, it is necessary to guide the subject to the ophthalmic device 10. In particular, when the subject undergoes an ophthalmic examination for the first time, examination guidance is required. On the other hand, in the ophthalmic system 1 of the present disclosure, by executing the examination guidance process, the subject can be guided to the ophthalmic device 10. Moreover, since the examination guidance process is executed after the presence of the subject is detected until the start of the ophthalmic examination, the execution of the ophthalmic examination by the examiner can be started smoothly (steps S5 of FIG. 3, steps S53 to S55 of FIG. 6).

[0096] The device control unit 20 of the ophthalmic system 1 of the present disclosure displays inspection guidance images (42a, 43a, 45a) on the monitor unit 15 and executes inspection guidance processing (steps S42, S43, and S45 in FIG. 4, FIGS. 5B, 5C, and 5E). Here, for example, if the inspection guidance processing is performed only by characters displayed on the monitor unit 15 without an image and / or sounds output from the subject speaker 16, there is a possibility that the subject may not be able to understand the inspection guidance. In contrast, in the ophthalmic system 1 of the present disclosure, inspection guidance images (42a, 43a, 45a) are displayed on the monitor unit 15 and inspection guidance processing is executed. Therefore, the subject can understand the inspection guidance.

[0097] The device control unit 20 of the ophthalmic system 1 of the present disclosure executes inspection guidance processing by character images (42b, 43b, 45b) displayed on the monitor unit 15 in accordance with the inspection guidance images (42a, 43a, 45a) (steps S42, S43, and S45 in FIG. 4, FIGS. 5B, 5C, and 5E). That is, in addition to the inspection guidance images (42a, 43a, 45a), character images (42b, 43b, 45b) are used. Therefore, the subject can easily understand the inspection guidance.

[0098] The ophthalmic device 10 of the ophthalmic system 1 of the present disclosure includes a subject speaker 16. After it is detected that the subject has set their face on the ophthalmic device 10 (specifically, the face support unit 12) (step S45 in FIG. 4), the device control unit 20 provides notification to the subject only by sounds output from the subject speaker 16. Here, during the inspection, since the subject has their face set on the ophthalmic device 10, for example, even if notification to the subject is displayed on the monitor unit 15, there is a possibility that the subject may not be able to visually observe the display information displayed on the monitor unit 15. Therefore, the subject is not notified by the image or the like displayed on the monitor unit 15. In contrast, in the ophthalmic system 1 of the present disclosure, during the inspection, since the subject has their face set on the ophthalmic device 10, notification to the subject is performed only by sounds output from the subject speaker 16. Therefore, even when the subject has their face set on the ophthalmic device 10, notification to the subject can be surely performed.

[0099] As described above, the ophthalmic system 1 of the present disclosure has been described based on Example 1. However, the specific configuration is not limited to Example 1, and design changes, additions, etc. are allowed as long as they do not depart from the gist of the invention according to each claim of the claims.

[0100] In step S1 of the above Example 1, an example was shown in which when a wake signal is output from the main body control unit 36 by an operation input of the operation unit 31 of the examiner, the process proceeds from step S1 to S2, and the ophthalmic device 10 shifts to the inspection mode. However, it is not limited to this, and the ophthalmic device 10 may shift to the inspection mode based on a wake setting of a calendar in which the date and time are set in advance. As described above, if "until the start of the remote operation of the examiner" is until the start of the hospital examination, the start time of the examination can be set in advance. Therefore, for example, based on a wake setting of a calendar in which the date and time of the start of the examination are set in advance, the device control unit 20 may shift the ophthalmic device 10 to the inspection mode.

[0101] The wake setting as described above may be stored in the memory of the device control unit 20 or may be stored in the memory of the remote operation device 30. If it is stored in the memory of the remote operation device 30, a wake signal is output from the main body control unit 36 to the device control unit 20 based on the wake setting. As a result, an operation input for shifting to the inspection mode by the examiner operating the operation unit 31 becomes unnecessary. Therefore, the burden on the examiner can be reduced.

[0102] Also, in step S11 of the above Example 1, an example was shown in which when a sleep signal is output by an operation input by the operation of the operation unit 31 of the examiner, the process proceeds from step S11 to S12, and the ophthalmic device 10 shifts to the sleep mode. However, it is not limited to this, and based on a wake setting of a calendar in which the date and time are set in advance, the device control unit 20 may shift the ophthalmic device 10 to the sleep mode. Similar to the above, if "until the start of the remote operation of the examiner" is until the start of the hospital examination, the end time of the examination can be set in advance. Therefore, for example, based on a sleep setting of a calendar in which the date and time of the end of the examination are set in advance, the device control unit 20 may shift the ophthalmic device 10 to the sleep mode.

[0103] The sleep setting as described above may be stored in the memory of the device control unit 20 or may be stored in the memory of the remote operation device 30. If it is stored in the memory of the remote operation device 30, based on the sleep setting, a sleep signal is output from the main body control unit 36 to the device control unit 20. As a result, operation input by the operation of the operator 31 of the examiner becomes unnecessary. Therefore, the burden on the examiner can be reduced.

[0104] In step S3 of the above-described Example 1, the examiner confirms the presence of the subject based on the subject display information, and the device control unit 20 determines whether the subject has been detected based on the presence detection information or the non-presence detection information input from the main body control unit 36. An example was shown. Also, in step S7 of the above-described Example 1, the examiner confirms the evacuation of the subject based on the subject display information, and the device control unit 20 determines whether the subject has evacuated based on the evacuation detection information or the non-evacuation detection information input from the main body control unit 36. An example was shown. However, it may be configured as in Modification Examples 1 to 4 below.

[0105] In Modification Example 1, the remote operation device 30 may have a subject detection function for detecting the subject, and the subject detection function may detect the presence of the subject. The subject detection function is a function that automatically outputs the presence detection information or the non-presence detection information in step S3 and the evacuation detection information or the non-evacuation detection information in step S7. For example, an artificial intelligence processing unit (Artificial Intelligence) having a subject detection function may be mounted on the remote operation device 30. The artificial intelligence processing unit automatically detects the presence of the subject from the subject display information. In other words, the artificial intelligence processing unit automatically performs presence detection, non-presence detection, evacuation detection, and non-evacuation detection based on the subject display information.

[0106] Specifically, the artificial intelligence processing unit reads the AI model stored in the memory of the remote operation device 30. The AI model is a model created by learning features such as the skeletal information of a person who is the subject in order to detect the subject. The artificial intelligence processing unit automatically uses the AI model to recognize the presence of the subject from the subject display information (moving image) composed of a plurality of still images (captured images).

[0107] Therefore, in step S3, if the artificial intelligence processing unit recognizes that the presence of the subject is included in the subject display information, it means that the presence of the subject has been detected. On the contrary, if the artificial intelligence processing unit recognizes that the presence of the subject is not included in the subject display information, it means that the presence of the subject has not been detected. Then, automatically, presence detection information or non-presence detection information is output from the artificial intelligence processing unit to the device control unit 20 through the main body control unit 36. Also, in step S7, if the artificial intelligence processing unit recognizes that the presence of the subject is not included in the subject display information, it means that the evacuation of the subject has been detected. On the contrary, if the artificial intelligence processing unit recognizes that the presence of the subject is included in the subject display information, it means that the evacuation of the subject has not been detected. Then, automatically, evacuation detection information or non-evacuation detection information is output from the artificial intelligence processing unit to the device control unit 20 through the main body control unit 36. This eliminates the need for the examiner to confirm the presence of the subject. Therefore, the burden on the examiner can be reduced.

[0108] In Modification 2, the above-described subject detection function may be possessed by the device control unit 20 instead of the remote operation device 30, and the device control unit 20 having the subject detection function in the same manner as above detects the presence of the subject. Then, the device control unit 20 makes a determination in step S3 based on the presence detection information or non-presence detection information, and makes a determination in step S7 based on the evacuation detection information or non-evacuation detection information. This eliminates the need for the examiner to confirm the presence of the subject. Therefore, the burden on the examiner can be reduced. In the case where the subject detection function is the artificial intelligence processing unit, it is assumed that the AI model is stored in the memory of the device control unit 20.

[0109] In Modification 3, the above-described subject detection function may be provided in the subject camera 18 instead of the remote control device 30. Similar to the above, the subject camera 18 having the subject detection function detects the presence of the subject. Then, presence detection information, non-presence detection information, evacuation detection information, or non-evacuation detection information is output from the subject camera 18 to the apparatus control unit 20. As a result, it is not necessary for the examiner to confirm the presence of the subject. Therefore, the burden on the examiner can be reduced. When the subject detection function is an artificial intelligence processing unit, the subject camera 18 is provided with an arithmetic circuit composed of various processors and memories (storage units) similar to the apparatus control unit 20 of the first embodiment, and the AI model is stored in the memory provided in the subject camera 18.

[0110] In Modification 4, as shown in FIG. 7, the apparatus control unit 20 may have a human presence sensor 19, and the human presence sensor 19 may detect the presence of the subject. The human presence sensor 19 is disposed, for example, below the subject microphone 17 and connected to the apparatus control unit 20. The human presence sensor 19 automatically senses whether or not a subject is present. The sensing range of the human presence sensor 19 is, for example, the space on the front side of the ophthalmic apparatus 10. Preferably, the sensing range of the human presence sensor 19 is the space on the front side of the face support portion 12. The human presence sensor 19 outputs the sensed result as information (signal) indicating the presence or absence of the subject to the apparatus control unit 20.

[0111] Then, based on the information indicating the presence or absence of the subject from the human presence sensor 19, the apparatus control unit 20 determines the presence detection or non-presence detection of the subject and the non-evacuation detection or evacuation detection of the subject. Specifically, when information indicating the presence is input, the apparatus control unit 20 determines presence detection in step S3 and non-evacuation detection in step S7. Conversely, when information indicating the absence is input, the apparatus control unit 20 determines non-presence detection in step S3 and evacuation detection in step S7. As a result, it is not necessary for the examiner to confirm the presence of the subject. Therefore, the burden on the examiner can be reduced.

[0112] Also, as in Modifications 1 to 4, the apparatus control unit 20 determines whether or not the subject has been detected in step S3 based on the information on the presence or absence of the subject from the artificial intelligence processing unit or the human presence sensor 19. For this reason, similar to the operation of the ophthalmic system 1 of the first embodiment, on the condition that the subject is present, the presence of the examiner is clearly indicated to the subject. Therefore, the ophthalmic apparatus 10 can clearly indicate to the subject that it is connected to the remote operation device 30. As a result, even when the subject cannot confirm with the person in charge whether the ophthalmic apparatus 10 is connected to the remote operation device 30, the subject can undergo an ophthalmic examination with peace of mind.

[0113] In the above Modification 3, in the sleep mode, it is assumed that the subject camera 18 and the artificial intelligence processing unit are operating. Then, in the sleep mode, since the presence detection information is automatically output from the subject camera 18 to the apparatus control unit 20, the apparatus control unit 20 may be regarded as having received a wake-up signal. That is, when the presence detection information is output from the subject camera 18 to the apparatus control unit 20, it is determined as YES in step S1 of FIG. 3. As a result, the examiner does not need to perform an operation input by operating the operation unit 31. Therefore, the burden on the examiner can be reduced. Note that when the presence detection information is output from the subject camera 18 to the remote operation reception unit 22, the remote operation reception unit 22 may determine that it has received a wake-up signal.

[0114] Also, in the above Modification 4, in the sleep mode, it is assumed that the human presence sensor 19 is operating. Then, in the sleep mode, since the information indicating the presence of a person is output from the human presence sensor 19 to the apparatus control unit 20, the apparatus control unit 20 may be regarded as having received a wake-up signal. That is, when the information indicating the presence of a person is output from the human presence sensor 19 to the apparatus control unit 20, it is determined as YES in step S1 of FIG. 3. As a result, the examiner does not need to perform an operation input by operating the operation unit 31. Therefore, the burden on the examiner can be reduced. Note that when the presence detection information is output from the human presence sensor 19 to the remote operation reception unit 22, the remote operation reception unit 22 may determine that it has received a wake-up signal.

[0115] In the above-described Example 1, an example was shown in which both the subject display information of the subject camera 18 and the examiner display information of the examiner camera 35 are moving images (videos), but the present invention is not limited to this. Both the subject display information and the examiner display information may be still images, or only one of the subject display information and the examiner display information may be a still image. In the case of a still image, for example, the subject camera 18 and the examiner camera 35 capture still images every few seconds. Then, the main body control unit 36 displays the still image captured by the subject camera 18 as subject display information (captured image, display information) on the examiner monitor unit 32. Thereby, the examiner can confirm the still image as the subject display information. Further, the apparatus control unit 20 displays the still image captured by the examiner camera 35 as examiner display information (captured image, display information) on the monitor unit 15. Thereby, the subject can confirm the still image as the examiner display information.

[0116] In addition, the artificial intelligence processing unit shown in Modifications 1 to 3 above can similarly recognize the presence of the subject even when the subject display information changes from a moving image to a still image. The reason is that, as described above, the artificial intelligence processing unit automatically uses an AI model to recognize the presence of the subject from the subject display information (moving image) composed of a plurality of still images (captured images). That is, the artificial intelligence processing unit recognizes the presence of the subject from a plurality of still images constituting the moving image.

[0117] In the above-described Example 1, an example in which the lens used for the subject camera 18 is not particularly limited was shown. However, 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 apparatus 10 than when using other lenses or the like. That is, the subject camera 18 can photograph not only the subject in the examination posture but also the subjects present in the X direction of the ophthalmic apparatus 10 (or around the ophthalmic apparatus 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 even more.

[0118] In steps S42, S43, and S45 of the above-described Example 1, an example in which the apparatus control unit 20 executes the examination guidance process based on the character images (42b, 43b, 45b) displayed on the monitor unit 15 in accordance with the examination guidance images (42a, 43a, 45a) was shown, but the present invention is not limited thereto. That is, examination guidance images may also be displayed on the monitor unit 15 in steps S41, S44, S46, and S47. Further, in steps S41 and S44, the examination guidance process may be executed based on the character images (41b and 44b) displayed on the monitor unit 15 in accordance with the examination guidance images. The same may apply to steps S46 and S47. Further, instead of the character images (42b, 43b, 45b), the apparatus control unit 20 may execute the examination guidance process based on the sound (examination guidance sound for examination guidance processing, guidance voice information) output from the subject speaker 16 in accordance with the examination guidance images (42a, 43a, 45a) (voice control). For this reason, the subject can easily understand the examination guidance. Further, the apparatus control unit 20 may execute the examination guidance process based on the character images (42b, 43b, 45b) displayed on the monitor unit 15 and the sound output from the subject speaker 16 in accordance with the examination guidance images (42a, 43a, 45a). For this reason, the subject can more easily understand the examination guidance.

[0119] In step S4 of the above-described Example 1, an example was shown in which when proceeding to step S4, guidance display information is automatically displayed on the monitor unit 15, but it is not limited to this. In step S4, when proceeding to step S4, the subject speaker 16 may output guidance voice information by automatically inputting the guidance voice information from the device control unit 20 to the subject speaker 16 (voice control). The guidance voice information is information for guiding the subject to the ophthalmic device 10.

[0120] In the above-described Example 1, an example was shown in which immediately after the subject's posture was detected (YES in step S3), the device control unit 20 executes the inspection guidance process (step S4), but it is not limited to this. For example, after executing the on control of the interactive function (step S52), the device control unit 20 may execute the inspection guidance process. In short, the inspection guidance process may be executed after the presence of the subject is detected (YES in step S3 of FIG. 3) until the start of the ophthalmic examination using the ophthalmic device 10 by the examiner (step S53 of FIG. 6). Thereby, the examiner can guide the subject to the ophthalmic device 10 using the ophthalmic device 10, and can smoothly start the execution of the ophthalmic examination by the examiner.

[0121] In step S44 of the above-described Example 1, an example was shown in which "Standby" is displayed on the monitor unit 15, and an example was shown in which the subject has no means to notify the examiner that the subject himself / herself is in standby, but it is not limited to this. On the monitor unit 15 of Example 1, a standby button may be displayed together with the display of "Standby". In accordance with the display of the standby button, the inspection guidance process may be executed by the display of a character image and / or a sound output from the subject speaker 16 that prompts the touch of the button. Thereby, when proceeding to step S44, the subject can notify the examiner that the subject is in standby. Further, after the presence of the subject is detected (YES in step S3 of FIG. 3), the examiner does not need to confirm whether the subject has reached the standby state (step S44), and the burden on the examiner can be reduced. Furthermore, it is possible to expect that the standby time of the subject will be shortened regardless of the timing of this examiner's confirmation.

[0122] In the above-described Example 1, the apparatus control unit 20 was shown as an example where the step of displaying the actual examiner's posture (examiner image 40) on the monitor unit 15 is step S45, but it is not limited to this. For example, the apparatus control unit 20 may display the examiner image 40 on the monitor unit 15 immediately after the presence of the subject is detected (YES in step S3 of FIG. 3). In short, after shifting to the inspection mode (step S2 in FIG. 3), the apparatus control unit 20 makes the condition that the presence of the subject is detected (YES in step S3 of FIG. 3), and may display the examiner image 40 on the monitor unit 15 until the start of the ophthalmic examination using the ophthalmic apparatus 10 by the examiner (processing in step S52). However, it is a condition that the examiner camera 35 is in the process of photographing the examiner when the examiner is at least in a position where the remote control device 30 can be operated.

[0123] In order to display the examiner image 40 on the monitor unit 15 in this way, the ophthalmic apparatus 10 can clearly show the subject that it is connected to the remote control device 30. Thereby, even when the subject cannot confirm with the person in charge whether the ophthalmic apparatus 10 is connected to the remote control device 30 or not, the subject can receive the ophthalmic examination with peace of mind.

[0124] In the above-described Example 1, an example where the examiner image 40 regarding the examiner displayed on the monitor unit 15 is the actual examiner's posture was shown, but it is not limited to this. For example, the examiner image 40 may be a character image displayed as a proxy for the examiner. And after shifting to the inspection mode (step S2 in FIG. 3), the apparatus control unit 20 makes the condition that the presence of the subject is detected (YES in step S3 of FIG. 3), and may display the character image as the examiner image 40 on the monitor unit 15 until the start of the ophthalmic examination using the ophthalmic apparatus 10 by the examiner (processing in step S52).

[0125] Since the character image displayed as the proxy of the examiner is displayed on the monitor unit 15 as the examiner image 40 in this way, even if it is a character image, the ophthalmic apparatus 10 can clearly show the subject that it is connected to the remote control device 30. Thus, even when the subject cannot confirm with the person in charge whether the ophthalmic apparatus 10 is connected to the remote control device 30, the subject can undergo an ophthalmic examination with peace of mind. Further, since the character image is displayed on the monitor unit 15, not only the voice of the examiner can be heard by the subject, and the possibility of giving the subject a sense of discomfort can be reduced or eliminated.

[0126] Furthermore, depending on the personality of the subject, it may be easier to talk with the character image as the examiner image 40 than with the actual examiner's appearance as the examiner image 40. Especially for children such as infants, the possibility of undergoing an ophthalmic examination without aversion is increased when the character image (for example, a character image such as an anime) is used as the examiner image 40 rather than the actual examiner's appearance as the examiner image 40. Therefore, smooth communication with the subject can be achieved, and the ophthalmic examination by the examiner can be carried out smoothly.

[0127] Here, the character may be a character displayed like a doppelganger of the examiner, that is, an avatar (imitating the examiner), or may be a character such as an anime. The character image may be a still image drawn two-dimensionally or three-dimensionally, or may be an image linked to the actions of the actual examiner. The image linked to the actions of the actual examiner is, for example, an image displayed by "Virtual YouTuber (VTuber)" or the like.

[0128] Furthermore, when the character image is displayed on the monitor unit 15 as the examiner image 40, the examiner does not necessarily have to be present at a position where the remote control device 30 can be operated. That is, the actual subject's figure is not displayed on the monitor unit 15 as the examiner image 40. Therefore, for example, even when the examiner is present in a room different from the room where the remote control device 30 is installed, it is possible to display the character image on the monitor unit 15 as the examiner image 40. In short, regardless of whether the examiner is present at a position where the remote control device 30 can be operated (the necessity of the examiner's presence), it is possible to display the character image on the monitor unit 15 as the examiner image 40.

[0129] Thereby, regardless of the necessity of the examiner's presence, after shifting to the inspection mode (step S2 in FIG. 3), the apparatus control unit 20 can display the character image on the monitor unit 15 as the examiner image 40 until the start of the ophthalmic examination using the ophthalmic apparatus 10 by the examiner (the process of step S52), provided that the presence of the subject is detected (YES in step S3 in FIG. 3).

[0130] Therefore, even when the examiner is not present at a position where the remote control device 30 can be operated, the ophthalmic apparatus 10 can clearly show the subject that it is connected to the remote control device 30 by the character image. Thereby, even when the subject cannot confirm with the person in charge whether the ophthalmic apparatus 10 is connected to the remote control device 30, the subject can undergo the ophthalmic examination with confidence. Furthermore, since the examiner does not necessarily have to be present at a position where the remote control device 30 can be operated until the ophthalmic examination, the burden on the examiner can be reduced.

[0131] In step S45 of the above-described first embodiment, an example was shown in which the examiner's display is shown on the monitor unit 15 until the determination of the end of the examination in step S54, but it is not limited to this. For example, in the examination execution process of step S5, the examiner's display does not necessarily have to be shown on the monitor unit 15. However, when the examination is interrupted or ended during the examination execution process of step S5, the examiner's display may be shown on the monitor unit 15.

[0132] In the above-described Example 1, after shifting to the inspection mode (step S2 in FIG. 3), the apparatus control unit 20 displays the examiner image 40 on the monitor unit 15 until the start of the ophthalmic examination using the ophthalmic apparatus 10 by the examiner (the process of step S52). Further, an example was shown in which "until the start of the examination using the ophthalmic apparatus 10 by the examiner" is until the on-control of the interactive function in step S52 (step S52). However, it is not limited to this. In short, "until the start of the examination using the ophthalmic apparatus 10 by the examiner" may be any processing step immediately before "the execution of the ophthalmic examination (step S53)", so it may be a processing step different from the on-control of the interactive function.

[0133] "Until the start of the examination using the ophthalmic apparatus by the examiner" preferably means until the subject sets his or her face on the face support unit 12. In other words, it means until the face of the subject is supported by the face support unit 12. Thereby, since the examiner image 40 (the actual appearance of the examiner, the character image) is displayed on the monitor unit 15, the ophthalmic apparatus 10 can surely show the subject that it is connected to the remote control device 30.

[0134] In the above-described Example 1, an example was shown in which the step of executing the on-control of the interactive function is step S52, but it is not limited to this. For example, the execution of the on-control of the interactive function may be immediately after the examiner image 40 (the actual appearance of the examiner, the character image) is displayed on the monitor unit 15. However, the apparatus control unit 20 executes the on-control of the interactive function at least when the examiner is present at a position where the remote control device 30 can be operated. That is, immediately after the examiner image 40 is displayed on the monitor unit 15, the subject can start interacting with the examiner. For this reason, the subject can receive the ophthalmic examination with more peace of mind. Further, since the examiner is at least present at a position where the remote control device 30 can be operated, it is possible for the examiner and the subject to communicate more smoothly when the interactive function is turned on than when the interactive function is turned off. Also, the subject can convey a request to the examiner. For example, the request may be "I want to go to the toilet, so please wait a little."

[0135] In step S46 of the above-described Example 1, the examiner confirms the setting of the subject's face, and an example is shown in which the apparatus control unit 20 determines whether or not the subject has set the face based on the set detection information or the set non-detection information input from the main body control unit 36. However, it may be configured as in the following Modification Examples 5 and 6.

[0136] In Modification Example 5, the artificial intelligence processing units from Modification Examples 1 to 3 automatically detect whether or not the subject has set his / her own face in the face support unit 12 from the subject display information. In other words, the artificial intelligence processing unit automatically performs set detection and non-set detection from the subject display information. Similar to Modification Examples 1 to 3 above, it is assumed that an AI model for performing set detection and non-set detection is stored in the memory. The AI model for performing set detection and non-set detection is a model created by learning features such as the skeletal information of a person who is the subject in order to detect whether or not the face has been set. The artificial intelligence processing unit automatically uses the AI model to recognize whether or not the face has been set from the subject display information (moving image or still image).

[0137] Therefore, in step S46, if the artificial intelligence processing unit recognizes that the setting of the face is included in the subject display information, it means that the setting of the face has been detected. On the contrary, if the artificial intelligence processing unit recognizes that the setting of the face is not included in the subject display information, it means that the setting of the face has not been detected. Then, automatically, similar to Modification Examples 1 to 3 above, the set detection information or the set non-detection information is output to the apparatus control unit 20. As a result, it is not necessary for the examiner to confirm whether or not the face has been set. Therefore, the burden on the examiner can be reduced.

[0138] In Modification Example 6, touch sensors are provided on the jaw receiving portion 12a and the forehead abutting portion 12b, respectively. Each touch sensor is connected to the device control unit 20. Each touch sensor is a general one that senses when a person's skin touches or when pressure is applied. Each touch sensor outputs the sensed result to the device control unit 20 as set detection information or set non-detection information. Then, the device control unit 20 determines set detection or set non-detection based on the information on the presence or absence of the subject from each touch sensor. Specifically, when the device control unit 20 receives set detection information from both touch sensors, it determines set detection in step S46. Conversely, when the device control unit 20 receives set non-detection information from at least one of the touch sensors, it determines set non-detection in step S46. This eliminates the need for the examiner to confirm the presence of the subject. Therefore, the burden on the examiner can be reduced.

[0139] Even when configured as in Modification Examples 5 and 6, after determining set detection, in the process of step S46, the device control unit 20 switches the notification to the subject to only the sound output from the subject speaker 16. Thus, in Modification Examples 5 and 6, similar to the operation of the ophthalmic system 1 of the first embodiment, in the ophthalmic system 1 of the present disclosure, after determining set detection, the notification to the subject is performed only by the sound output from the subject speaker 16. Therefore, in Modification Examples 5 and 6, even when the subject has set their face on the ophthalmic device 10, the notification to the subject can be reliably performed.

[0140] In the above-described Example 1, after the apparatus control unit 20 shifts to the inspection mode (step S2 in FIG. 3), an example was shown in which the examiner image 40 is displayed on the monitor unit 15 before the start of the ophthalmic examination using the ophthalmic apparatus 10 by the examiner. However, an example was shown in which the apparatus control unit 20 makes it a condition that the presence of the subject is detected based on the subject display information from the subject camera 18 (YES in step S3 in FIG. 3). However, the timing at which the apparatus control unit 20 displays the examiner image 40 on the monitor unit 15 is not limited to this. After the apparatus control unit 20 shifts to the inspection mode (step S2 in FIG. 3), if it is made a condition that the presence of the subject is detected based on the subject display information from the subject camera 18 (YES in step S3 in FIG. 3), the timing may be different from that in Example 1. Thus, even if the timing at which the apparatus control unit 20 displays the examiner image 40 on the monitor unit 15 is changed, when the examiner remotely operates the ophthalmic apparatus 10 using the remote control device 30, the ophthalmic apparatus 10 can clearly show the subject that it is connected to the remote control device 30.

[0141] In the above-described Example 1, an example was shown in which step S of the subject setting his or her face on the face support unit 12 according to the examiner's instruction is step S46, but it is not limited to this. The timing at which the subject sets his or her face on the face support unit 12 may be any time after the presence of the subject is detected (YES in step S3 in FIG. 3) and before the start of the examination using the ophthalmic apparatus 10 by the examiner. The timing at which the subject sets his or her face on the face support unit 12 follows the examiner's instruction, but it may also be the subject's own timing.

[0142] In step S48 of the above-described Example 1, an example was shown in which the subject speaker 16 outputs automatic voice information or examiner voice information, but it is not limited to this. For example, the display information in FIG. 5B may be output as operation information from the main body control unit 36 to the apparatus control unit 20 by operating the examiner's operation unit 31, and the process of step S48 may be executed by the apparatus control unit 20.

[0143] In step S51 of the above-described Example 1, an example was shown in which when proceeding to step S51, the subject speaker 16 automatically outputs automatic voice information. However, it is not limited to this. In step S51, when proceeding to step S51, automatic display information may be displayed on the monitor unit 15 automatically by input of the automatic display information from the apparatus control unit 20 to the monitor unit 15 (display control). However, after it is detected that the subject has set his / her face on the ophthalmic apparatus 10, it is not displayed on the monitor unit 15.

[0144] In step S54 of the above-described Example 1, an example was shown in which the apparatus control unit 20 determines whether the ophthalmic examination has actually ended. However, it is not limited to this. For example, after asking the examiner to the subject "May I end the examination?" etc., if the subject's answer is YES, it proceeds to step S55, and if NO, it returns to step S53. As described in steps S52 and S53, the examiner and the subject can communicate with each other. In the case of YES, by the operation of the operation unit 31 of the examiner, an examination end command (control signal) is input to the apparatus control unit 20 through the main body control unit 36. In step S55, following the input of the examination end command, off control of the interactive function is performed and it proceeds to the end of the examination execution process. The examination end command may be in a mode to turn off the interactive function.

[0145] In step S6 of the above-described Example 1, an example was shown in which the apparatus control unit 20 automatically performs the examination end notification process. However, it is not limited to this. For example, the examiner may notify the subject through the examiner microphone 34 that the examination has ended. Or, end notification display information may be output as operation information from the main body control unit 36 to the apparatus control unit 20 by the operation of the operation unit 31 of the examiner, and the process of step S6 may be executed by the apparatus control unit 20.

[0146] In the above-described Example 1, the subject camera 18 was shown as an example provided above the monitor unit 15, but it is not limited thereto. For example, the subject camera 18 may be a measurement camera (optical system for imaging, camera, etc.) included in the measurement head 14. In the case of a measurement camera, since it is for measurement, it is provided at least at a position where the subject in the inspection posture is reflected. In this case, the examiner can perform the presence confirmation of the subject in step S3 and the evacuation confirmation of the subject in step S7. Also, in this case, the examiner can observe the state of the subject before, during, and after the inspection by the display on the examiner monitor unit 32. Further, the examiner can use the display on the examiner monitor unit 32 for the position adjustment between the ophthalmic apparatus 10 and the subject.

[0147] In the above-described Example 1, an example in which the auto-ref keratometer 14A is provided in the measurement head 14 was shown, but a non-contact tonometer or the like may be provided. The non-contact tonometer measures the intraocular pressure value of the eye to be examined without contact.

[0148] The ophthalmic system 1 of the above-described Example 1 was shown as an example including one ophthalmic apparatus 10 and one remote operation device 30 as shown in FIG. 1, but the ophthalmic system 1A in FIG. 8 may also be used as a modification 7. For example, as shown in FIG. 8, the modification 7 includes three ophthalmic apparatuses 10A, 10B, and 10C. A communication network such as a router 100A (router device) and the Internet 101 is connected between the three ophthalmic apparatuses 10A, 10B, and 10C and one remote operation device 30A. The remote operation device 30A outputs a wake signal or a sleep signal to each of the three ophthalmic apparatuses 10A, 10B, and 10C via the router 100A and the Internet 101.

[0149] The remote operation device 30A has the configuration of the remote operation device 30 in the first embodiment. Further, the remote operation device 30A has a configuration that can be connected to each of the three ophthalmic devices 10A, 10B, and 10C by switching the connection of the router 100A. Each of the three ophthalmic devices 10A, 10B, and 10C has the same configuration as that in the first embodiment. Each of the three ophthalmic devices 10A, 10B, and 10C can be remotely operated by the examiner when the router 100A is switched by the remote operation device 30A and connected to the remote operation device 30A.

[0150] With the configuration of the seventh modification, it is not necessary for the examiner to visit the remote location for the transition between the sleep mode and the inspection mode. For this reason, when the examiner remotely operates the three ophthalmic devices 10A, 10B, and 10C using the remote operation device 30A, the examiner can remotely perform the mode transition between the inspection mode and the sleep mode. In the seventh modification, three ophthalmic devices 10A, 10B, and 10C are used, but two or four or more, that is, a plurality of ophthalmic devices, can be connected to one remote operation device 30A, and the examiner can remotely perform the mode transition by remote operation.

A communication network such as a router (router device) and the Internet is connected between the one ophthalmic device and the plurality of remote operation devices. Thereby, the ophthalmic device and each remote operation device can communicate with each other. Only one of the plurality of remote operation devices may be able to output a wake signal or a sleep signal to the ophthalmic device via the router and the Internet. Also, communication may be possible between the plurality of remote operation devices so that the examiners in charge of each remote operation device can interact with each other.

[0152] In addition, the ophthalmic system of Modification Example 8 may include a plurality of ophthalmic devices and a plurality of remote operation devices. A router (router device) and a communication network such as the Internet are connected between the plurality of ophthalmic devices and the plurality of remote operation devices. Thereby, each ophthalmic device and each remote operation device can communicate with each other. Only one of the plurality of remote operation devices may be able to output a wake signal or a sleep signal to a predetermined ophthalmic device selected by the examiner among the plurality of ophthalmic devices via the router and the Internet. Further, a case where one remote operation device is outputting various signals to a predetermined ophthalmic device will be described. In this case, another remote operation device among the remaining remote operation devices may be able to output a wake signal or a sleep signal to another ophthalmic device selected by the examiner among the remaining ophthalmic devices via the router and the Internet. Also, the plurality of remote operation devices may be made communicable with each other so that the examiners in charge of each remote operation device can interact with each other.

[0153] In the above-described Example 1 and each modification, an example in which the communication interface 21 and the main body control unit 36 input and output various information to each other via the router 100 and the Internet 101 has been shown, but the present invention is not limited thereto. In short, the communication network connecting the communication interface 21 and the main body control unit 36 only needs to be able to input and output various information to each other and enable remote operation by the examiner.
