FIG. 3 is a diagram illustrating changing the layout of icons on the terminal device according to the embodiment.

This embodiment will be briefly described below. The terminal device (for example, the terminal device 10) of this embodiment operates, for example, a plurality of ophthalmological apparatuses (for example, the ophthalmological apparatus 1). The terminal device mainly includes, for example, a communication section (for example, the communication section 77, etc.), a selection reception section (for example, the display section 75, the operation section 76, etc.), a control section (for example, the control section 70), etc. . The communication unit communicates with, for example, an ophthalmological apparatus. The selection receiving unit receives, for example, a selection instruction to select at least one ophthalmological device to be operated from among the plurality of ophthalmological devices. For example, the control unit transmits a control signal to the ophthalmologic apparatus to be operated using the communication unit. This allows the examiner to easily operate multiple ophthalmological devices using the terminal device.

Note that the selection section may include, for example, a display section (for example, the display section 75, etc.) and an operation reception section (for example, the operation section 76, etc.). The display section displays, for example, an operation area for operating the ophthalmological apparatus. The operation area may be, for example, an icon, a screen, or the like. The operation reception unit receives, for example, an operation from the examiner. In this case, the control section causes the display section to display, for example, the first operation area (for example, the icon 21a, etc.) and the second operation area (for example, the icon 21b, etc.). The first operation area is an area displayed on the display unit for operating the first ophthalmologic apparatus. The second operation area is an area displayed on the display unit for operating a second ophthalmologic apparatus different from the first ophthalmologic apparatus. Furthermore, the control unit transmits a first control signal for operating the first ophthalmologic apparatus to the first ophthalmologic apparatus based on the operation on the first operation area received by the operation reception unit. The control unit also transmits a second control signal for operating the second ophthalmologic apparatus to the second ophthalmologic apparatus based on the operation on the second operation area received by the operation reception unit. In this way, the terminal device of this embodiment allows a plurality of ophthalmological apparatuses to be operated with a common terminal device.

Of course, when operating three or more ophthalmological apparatuses, three or more operation areas may be displayed on the display unit. For example, the n-th operation area (n is a natural number) is displayed on the display unit, and the n-th control signal for operating the n-th ophthalmological apparatus is sent to the n-th control signal based on the operation for the n-th operation area received by the operation reception unit. It may also be sent to an ophthalmological device.

Note that the control unit may transmit the first control signal and the second control signal to a plurality of ophthalmologic apparatuses. In this case, for example, it is preferable to provide an identifier for which device the control signal is directed to at the beginning. Accordingly, the plurality of ophthalmological apparatuses may receive the control signal corresponding to the identifier among the signals transmitted from the terminal device. Further, the control unit may transmit a control signal to a plurality of ophthalmologic apparatuses, and only the ophthalmologic apparatus in an active state may receive the control signal.

Note that the control unit may acquire the first observation image (for example, observation image 24a, etc.) and the second observation image (for example, observation image 24f, etc.) using the communication unit. The first observation image is, for example, an image of the subject's eye photographed by the first ophthalmologic apparatus. The second observation image is, for example, an image of the subject's eye photographed by the second ophthalmologic apparatus. In this case, the control unit causes the first observation image to be displayed in the first operation area, and causes the first observation image to be displayed in the second operation area. This allows the examiner to check observation images of multiple subjects measured by multiple ophthalmological devices.

Note that the control unit may display the first operation area and the second operation area on the display unit in a switchable manner. In this case, each operation area can be displayed in a large size on the display section, making it easy to see. Further, the control section may display the first operation area and the second operation area on the display section at the same time. In this case, the examiner can grasp the status of each ophthalmological device at a glance.

Note that the control unit may set either the first ophthalmologic apparatus or the second ophthalmologic apparatus as an operation target based on the operation on either the first operation area or the second operation area received by the operation reception unit. good. Of course, when operating three or more ophthalmological apparatuses, one of the first to nth ophthalmic apparatuses is selected based on the operation on either the first operation area or the n-th operation area received by the operation reception unit. may be set as the operation target. In this way, the control unit may set some of the ophthalmological apparatuses as operation targets among the plurality of ophthalmological apparatuses.

Note that the control unit may change the operation target based on the operation on either the first operation area or the second operation area received by the operation reception unit. For example, when the first ophthalmologic apparatus is set as the operation target, the control unit changes the operation target from the first ophthalmologic apparatus to the second ophthalmologic apparatus based on the operation on the second operation area received by the operation reception unit. You may. This allows the examiner to operate a desired ophthalmologic device among the plurality of ophthalmologic devices.

Note that, when the first ophthalmologic apparatus is set as the operation target, the control unit displays the first operation area on the display unit with emphasis on the first operation area rather than the second operation area for operating the second ophthalmology apparatus that is not the operation target. You may let them. For example, the control unit may cause the display unit to display the operation area corresponding to the ophthalmologic device to be operated in highlighted display, dark display, diagonal line display, or the like. Further, the control unit may display the operation area corresponding to the ophthalmological device to be operated brighter than other operation areas, or may display the operation area by partially changing the color.

In addition, when the first ophthalmologic apparatus is set as an operation target, the control unit causes the display unit to display the first operation area larger than the second operation area for operating the second ophthalmologic apparatus that is not the operation target. Good too. This makes it easy for the examiner to see the state of the ophthalmological device that is performing the measurement.

Note that the control unit may set the measurement order of the plurality of ophthalmological apparatuses based on the operation received by the operation reception unit. In this case, the control unit may sequentially highlight the plurality of operation areas according to the measurement order. This allows the examiner to easily understand which device to monitor or operate next.

Note that the control unit may identify whether the plurality of ophthalmologic apparatuses are in an active state or an inactive state based on status signals acquired from the plurality of ophthalmologic apparatuses via the communication unit.

Note that the control unit may transmit control signals to a plurality of ophthalmologic apparatuses through the communication unit to switch the ophthalmologic apparatuses between an active state and an inactive state. For example, the control unit may switch between an active state and an inactive state for each of a plurality of ophthalmological devices, or may switch a plurality of ophthalmological devices at once between an active state and an inactive state. The state may be switched.

Note that the control unit may set the measurement order of the plurality of ophthalmological apparatuses based on the operation received by the operation reception unit. For example, the control unit may set the order in which the operation areas corresponding to each ophthalmological apparatus are operated as the measurement order. For example, when measuring a second ophthalmic device after the first ophthalmic device according to the measurement order, when the measurement by the first ophthalmic device is completed, the control unit brings the first ophthalmic device into an inactive state and turns the second ophthalmic device into an inactive state. It may be in the active state.

Note that the control unit may display a mark reminiscent of the first ophthalmologic apparatus in the first operation area. For example, the name, nickname, graphics, etc. of the ophthalmological device may be displayed in the first operation area. Thereby, the examiner can easily understand which of the plurality of ophthalmological apparatuses the operation area corresponds to.

Note that the terminal device may further include a voice input section. In this case, the control unit may transmit the audio input received from the audio input unit to the audio output unit provided in the ophthalmologic apparatus to be operated, using the communication unit. This allows the examiner to verbally explain the test to the subject.

Note that the terminal device may further include an imaging unit. In this case, the control section may transmit the image received from the photographing section to an individual display section (for example, display section 7a, etc.) provided in the ophthalmologic apparatus to be operated, using the communication section. This allows the examiner to explain the test to the subject using gestures.

Note that the control unit may execute a terminal control program stored in a storage unit (eg, flash memory 72, storage unit 74, etc.). The terminal control program may include, for example, a selection acceptance step and a transmission step. The selection receiving step is, for example, a step of receiving a selection instruction to select at least one ophthalmological device to be operated from among a plurality of ophthalmological devices. The transmitting step is, for example, a step of transmitting a control signal to the ophthalmological apparatus to be operated.

Note that the terminal control program may include a display step, an operation reception step, a first transmission step, and a second transmission step. The display step is, for example, a step of displaying on the display a first operation area for operating the first ophthalmologic apparatus and a second operation area for operating a second ophthalmologic apparatus different from the first ophthalmologic apparatus. It is. The operation accepting step is, for example, a step of accepting an operation to the first operation area or the second operation area. The first transmitting step is, for example, a step of transmitting a first control signal for operating the first ophthalmologic apparatus to the first ophthalmologic apparatus based on the operation on the first operation area received in the operation reception step. The second transmitting step is, for example, a step of transmitting a second control signal for operating the second ophthalmologic apparatus to the second ophthalmologic apparatus based on the operation on the second operation area received in the operation reception step.

Note that the ophthalmologic apparatus operated by the terminal device may include, for example, a notification section (for example, an indicator light 8, an audio output section 9a, a display section 7a, etc.). For example, the notification unit may notify the examiner or the subject that the object is to be operated by a terminal device.

Note that the control unit may cause the display unit to display a confirmation screen (for example, the icon screen 20, etc.) on which the status of the plurality of ophthalmologic apparatuses can be confirmed. Since the examiner can check the status of multiple ophthalmological devices at a glance on the confirmation screen, he or she can quickly respond to abnormalities in the devices.

Note that a plurality of ophthalmological apparatuses may be operated using a plurality of terminal devices. For example, the same ophthalmologic device may be associated with multiple terminal devices. In such a case, the terminal device that acquired operating authority first operates the ophthalmological device, and the terminal device that acquired operating authority later is prevented from operating until the terminal device that acquired operating authority first finishes operating it. It's okay.

Note that the ophthalmological apparatus operated by the terminal device may be an objective optometric apparatus or a subjective optometric apparatus.

<Example>
The terminal device of this embodiment will be explained below. The terminal device 10 of this embodiment operates, for example, a plurality of ophthalmological devices 1 (see FIG. 1). For example, the terminal device 10 is communicably connected to a plurality of ophthalmological devices 1. For example, the terminal device 10 is connected to the plurality of ophthalmological devices 1 by at least one of wireless and wired connections. For example, the terminal device 10 may transmit a command signal and the like to the ophthalmological apparatus 1 and receive measurement results and the like from the ophthalmological apparatus 1 . Note that the terminal device 10 may be, for example, a tablet PC, a notebook PC, a smartphone, a desktop PC, or the like.

The terminal device 10 includes, for example, a control section 70, a communication section 77, an operation section 76, a display section 75, and the like. The control unit 70 is realized by, for example, a general CPU (Central Processing Unit) 71, a flash memory 72, a RAM 73, and the like. The flash memory 72 stores various programs, initial values, etc. for controlling the operation of the terminal device 10. The RAM 73 temporarily stores various information. Note that the control unit 70 may be configured by a plurality of control units (that is, a plurality of processors).

As shown in FIG. 2, the control section 70 is electrically connected to, for example, a storage section 74, an operation section 76, a display section 75, a communication section 77, and the like. The storage unit 74 is a non-transitory storage medium that can retain stored contents even if the power supply is cut off. For example, a hard disk drive, flash ROM, removable USB memory, etc. can be used as the storage unit 74.

The communication unit 77 communicates with a plurality of ophthalmological apparatuses 1, for example. For example, the communication unit 77 may transmit and receive radio waves and the like to and from each ophthalmologic apparatus 1 . The communication unit 77 may communicate with the ophthalmological apparatus 1 using, for example, wireless LAN, infrared communication, WiFi (registered trademark), Bluetooth (registered trademark), or the like. An internet line may also be used. Of course, the communication unit 77 may communicate with each ophthalmological apparatus 1 through a wired connection such as a USB cable or a LAN cable.

The display unit 75 displays, for example, an operation screen corresponding to each ophthalmologic apparatus 1 and measurement results received from each ophthalmologic apparatus 1. A display of a personal computer (hereinafter referred to as "PC") may also be used. Multiple displays may be used together. Further, the display section 75 may have a touch panel function.

The operating unit 76 receives various operating instructions from the examiner. The operation unit 76 outputs an operation signal to the control unit 70 according to the input operation instruction. For the operation unit 76, at least one user interface such as a touch panel, a mouse, a joystick, a keyboard, etc. may be used. Note that when the display section 75 is a touch panel, the display section 75 also functions as an operation section 76.

As shown in FIG. 3, for example, an icon screen 20 is displayed on the display unit 75. The icon screen 20 is a screen for checking the status of each ophthalmological device 1 and performing operations. On the icon screen 20, icons 21 corresponding to each ophthalmologic apparatus 1 are displayed. The icon 21 may be, for example, the screen itself displayed on the display unit 7a of the ophthalmologic apparatus, may include an image, shape, name, nickname, etc. that reminds one of each ophthalmologic apparatus 1, or may be a combination of these. The icons of this embodiment have the shape of an operation screen on which external views 22a to 22f of each device are displayed (see FIG. 3). For example, the icons 21a to 21f may have a common form or may have different forms.

On the icon screen 20, a plurality of icons 21 corresponding to each ophthalmological apparatus 1 are displayed. For example, the control unit 70 causes the display unit 75 to display icons corresponding to different ophthalmological apparatuses 1 side by side. The examiner confirms the status, measurement results, etc. of each ophthalmological apparatus 1 using the icons 21 displayed on the display section 75. Further, the examiner may operate each ophthalmologic apparatus 1 by performing a specific operation input on the icon 21 displayed on the display unit 75.

<About ophthalmological equipment>
The ophthalmological apparatus 1 connected to the terminal device 10 includes, for example, an eye refractive power measurement device, a non-contact tonometer, an axial length measurement device, a corneal endothelial cell imaging device, an optical tomography imaging device, a fundus imaging device, and a local visual field. It may be a meter, a corneal topography measuring device, a refractor, or the like. The ophthalmological apparatus 1 of this embodiment includes an optometry section 2 and a drive section 3, and measures a subject fully automatically. Therefore, the examiner does not need to operate each device by the side, and only needs to check the status and measurement results of the ophthalmological device 1 from a remote location using the terminal device 10.

For example, as shown in FIG. 2, the ophthalmologic apparatus 1 may include an optometry section 2, a control section 7, a communication section 5, a base 6, a face support section 4, a drive section 3, and the like. The control unit 7 is connected to the optometry unit 2, the communication unit 5, the drive unit 3, etc., and controls the ophthalmologic apparatus 1. The communication unit 5 communicates with the terminal device 10 . For example, the communication unit 5 transmits and receives radio waves to and from the communication unit 77 of the terminal device 10 . The optometry section 2 performs examinations (measurement, photography, etc.) of the eye to be examined. The optometry section 2 includes, for example, an observation optical system 2a, an examination optical system 2b, and the like. The observation optical system 2a and the inspection optical system 2b include, for example, a light source, an optical element (for example, a lens, a mirror, etc.), a light receiving element (for example, a CCD, etc.), and the like. The drive unit 3 may be provided on the base 6, for example, and move the optometry unit 2 in a three-dimensional direction with respect to the eye E to be examined. The face support section 4 supports the subject's face. The face support section 4 may include, for example, a chin rest 4a, a forehead rest 4b, and the like.

Furthermore, the ophthalmologic apparatus 1 may include a display section 7a, an audio output section (for example, a speaker, etc.) 9a, an audio input section (for example, a microphone, etc.) 9b, an indicator light (for example, a pilot lamp, etc.) 8, and the like. The display section 7a, the audio output section 9a, the audio input section 9b, and the indicator light 8 are connected to the control section 7, for example. The display unit 7a displays, for example, an operation screen, test results, and the like. The display section 7a may be provided on the subject's side, or may be provided on the opposite side to the subject, for example. The display unit 7a may be able to change the direction of the screen so as to face the subject.The audio output unit 9a outputs predetermined audio guidance stored in a storage unit (not shown) connected to the control unit 7. Alternatively, the audio input by the audio input unit 79 of the terminal device 10 may be output. For example, the voice of the subject is input to the voice input section 9b. The voice output section 9a and the voice input section 9b provided in the ophthalmological apparatus 1 and the terminal device 10 allow conversation, instructions, etc. even when the examiner and the subject are located at a distance.

The indicator light 8 may be arranged, for example, on the chin rest 4a, the forehead rest 4b, or the upper part of the main body. The indicator light 8 is lit, for example, when the device 1 is in an active state. For example, by checking the indicator light 8, the subject can determine whether the device 1 is in an active state (e.g., measurable state, power ON, etc.) or in an inactive state (e.g., sleep state, power saving state, power OFF). I can figure out if there is. Further, the control unit 7 may turn on or blink the indicator light 8 of the device that will perform the next measurement. Thereby, the subject can move to the next location of the ophthalmological apparatus 1 without getting lost. Note that the display section 7a may be used as the indicator light 8.

<Control operation>
A control operation when managing a plurality of ophthalmologic apparatuses 1 using the terminal device 10 as described above will be explained based on the flowcharts of FIGS. 4 and 5. For example, the examiner uses the terminal device 10 to check the status of each ophthalmological device 1 and provide measurement support.

Note that it is preferable that the examiner make settings to associate the terminal device 10 and the ophthalmological apparatus 1 (for example, pairing) before the measurement. For example, the control unit 70 may detect radio waves output from each ophthalmologic apparatus and store the information (for example, an identification signal) in the storage unit 74. Thereby, the control unit 70 can identify the radio waves from each ophthalmologic apparatus.

(Step S1)
First, the examiner sets the measurement order of the plurality of ophthalmological apparatuses 1A to 1F. For example, as shown in FIG. 6, the examiner may input the measurement order into the terminal device 10 by touching each of the icons 21a to 21f in the order in which the measurements are desired. When the icon 21 is touched, the display unit 75 detects the touch operation and transmits an operation signal to the control unit 70. The control unit 70 receives, for example, an operation signal from the display unit 75.

The control unit 70 receives the operation signal output from the display unit 75 and causes the storage unit 74 to store the order in which the icons 21 were touched. Note that the control unit 70 may change the display of the icon 21 touched by the examiner to indicate that it has been selected. For example, the control unit 70 may display the selected icon 21 in a highlighted display, a dark display, a diagonal line display, etc. (see, for example, FIGS. 6 and 7). Further, the control unit 70 may display numbers 23a to 23c indicating the measurement order near the selected icon 21. Note that the examiner does not need to select all the ophthalmological devices 1, but only needs to select the device that performs the measurement.

(Step S2)
The control unit 70 reads the measurement order set in step S1 from the storage unit 74, and starts controlling the device that performs the measurement first (for example, the first device 1A) (see FIG. 5). For example, the control unit 70 transmits an activation signal to the first device 1A through the communication unit 77 (step S2-1).

When the control unit 7 of the first device 1A receives the activation signal from the terminal device 10, it puts the first device 1A into an active state. Then, the control unit 7 of the first device 1A transmits the observation image 24 photographed by the optometry unit 2 to the terminal device 10. The terminal device 10 receives the observation image 24a from the first device 1A, and displays it on the display unit 75 (see FIG. 7). For example, the observation image 24a may be displayed in a partial area of the icon 21a of the first device 1A. In addition to the observation image 24a, the icon 21 may display necessary information such as the condition of the subject (for example, the state of contact between the face support section 4 and the face), the state of the device, and the like.

For example, the examiner may know that the first device 1A is in the active state by checking the observation image displayed on the icon of the first device 1A. For example, the examiner observes the observation image and monitors how automatic measurements are performed. The ophthalmological apparatus 1 automatically performs alignment and measurement.

Note that the terminal device 10 may transmit an operation signal to the ophthalmologic apparatus 1 in the active state (step S2-2). For example, the examiner may operate the ophthalmological apparatus 1 in the active state by inputting an operation to the icon 21 . For example, the examiner may move the apparatus in the XYZ directions by touching the observation screen 24a displayed on the icon 21a and performing a drag operation, a pinch operation, or the like. For example, the control unit 70 moves the optometry unit 2 of each ophthalmologic apparatus 1 in the XY direction in response to a drag operation by the examiner detected by the touch panel of the display unit 75, and moves the optometry unit 2 of each ophthalmology apparatus 1 in the XY direction in response to a pinch operation. The optometry section 2 may be moved in the Z direction (see Japanese Patent Application No. 2014-202700).

When the measurement of the eye E by the first device 1A is completed, the control unit 70 receives the measurement result (step S2-3). For example, the control unit 70 may periodically send a request signal for status information to the ophthalmological apparatus 1. The ophthalmological device 1 may send device status information to the terminal device 10 every time it receives a request signal from the control unit 70. Upon receiving the measurement completion status information from the ophthalmologic apparatus 1, the control unit 70 may request the ophthalmologic apparatus 1 to transmit the measurement results. For example, the ophthalmological apparatus 1 transmits the measurement results to the terminal device 10 when the measurement results are requested. Of course, the status information, measurement results, etc. may be unilaterally transmitted from the ophthalmological apparatus 1 to the terminal device 10 without a request from the terminal device 10.

Upon receiving the measurement results, the control unit 70 may cause the storage unit 74 to store the measurement results. Further, the control unit 70 may display the measurement results stored in the storage unit 74 in a part of the corresponding icon 21.

Note that, upon receiving the measurement results from the first device 1A, the control section 70 may send a stop signal to the first device 1A (step S2-4). When the first device 1A receives the stop signal, it becomes inactive. Since each ophthalmologic apparatus 1 is automatically controlled to become inactive based on the stop signal from the terminal device 10, unnecessary power consumption can be suppressed (see FIG. 8).

(Step S3)
After transmitting a stop signal to the first device 1A, the control unit 70 transmits a start signal to the second device 1B. Like the first device 1A, the second device 1B receives a measurement start signal from the control unit 70, measures the subject, and transmits the measurement results to the terminal device 10. When the terminal device 10 acquires the measurement result from the second ophthalmological device 1B, the terminal device 10 puts the second device 1B into an inactive state.

(Step S4)
By repeating the above-described control, the control unit 70 performs measurements in the order set in step S1, and obtains the measurement results measured by the plurality of ophthalmological apparatuses 1A to 1F. The examiner may issue instructions to the subject from the voice input section 79 of the terminal device 10 as necessary. When the measurement is completed in all the ophthalmological apparatuses 1 set in step S1, the control unit 70, for example, brings all the ophthalmological apparatuses 1 into an inactive state. Note that the control unit 70 may display a list of measurement results obtained by each device on the display unit 75.

In this way, by displaying the icons 21 corresponding to the plurality of ophthalmological apparatuses 1 on the display section 75, two or more ophthalmological apparatuses 1 can be managed and operated with one terminal device 10. Further, since a plurality of ophthalmological devices 1 can be operated with one terminal device 10, the examiner does not necessarily need to be near the device 1 and can operate it from a remote location. Furthermore, the examiner does not necessarily have to move from device to device, and can operate the device while remaining in the same location.

Further, since the measurement results can be confirmed and operated using the terminal device 10, it is not necessary to provide one or both of a display section and an operation section for each device.

Of course, a plurality of ophthalmological apparatuses 1 may be controlled by a plurality of terminal devices 10. In this case, only the terminal device 10 that has the operating authority first may be able to operate the ophthalmological apparatus. At this time, the other terminal devices 10 that do not have the operating authority may be kept waiting, and the operation status of the terminal device that has the operating authority may be displayed on the display unit 75.

Furthermore, when using a plurality of terminal devices 10, the ophthalmological devices may be divided into a plurality of groups, and a terminal device may be assigned to each group.

In the above example, the measurement order is set, and the active state and inactive state are automatically switched according to the set measurement order, but it may be switched according to the examiner's operation on the icon 21. For example, by touching the icon 21, the device 1 may be switched between an active state and an inactive state. For example, when the icon 21 in the inactive state is touched, the control unit 70 may transmit an activation signal for switching the target ophthalmological apparatus 1 to the active state. On the other hand, when the stop button 27 of the icon 21 in the active state is touched, the control unit 70 may transmit a stop signal for switching the target ophthalmological apparatus 1 to the inactive state (see FIGS. 7 and 8). ). The control unit 70 may then switch the icon 21 displayed on the display unit 75 to an inactive display.

Further, the control unit 70 may cause the display unit 75 to display the enlarged icon 21A when the icon 21a is operated. For example, when the examiner touches the icon 21a, the control unit 70 may receive an operation signal output from the touch panel and cause the display unit 75 to display the enlarged icon 21A. For example, as shown in FIG. 9, the enlargement icon 21A is displayed on the display section 75, thereby making it easier to check the observation image, operate the device, etc.

For example, as shown in FIGS. 9(a) and 9(b), when the enlarged icon 21A is displayed, when a specific operation such as a flick operation or a drag operation is performed on the enlarged icon 21A, the next measurement order is An enlarged icon 21F may be displayed. Of course, the control unit 70 may display the icons 21 before and after the measurement order when the icon switching buttons 28F, 28B, etc. are operated.

For example, when the enlarged icon 21A is displayed, when the measurement with the first device 1A is completed, the control unit 70 automatically displays the next enlarged icon 21F according to the measurement order set in step S1. You may switch.

Note that the enlarged icon 21A may return to its original icon size by operating the reduce button 26a. Of course, when the stop button 27 of the enlarged icon 21A is operated, the control unit 70 may return the enlarged icon 21A to the original icon 21a display and cause the first device 1A to become inactive.

In addition, in the above description, the display part 75 is provided with a touch panel function, and the control part 70 detects the examiner's touch input, but it is not limited to this. For example, the terminal device 10 may detect selection of the icon 21 based on an operation by another operation unit. For example, operating means such as a mouse and a keyboard may be used.

Note that the terminal device 10 may update various settings or software of each ophthalmological device 1. For example, the control unit 70 may download setting information, update software, etc. of each ophthalmologic apparatus 1 through an Internet line, and transmit the downloaded information to the ophthalmologic apparatus 1. The ophthalmological apparatus 1 may update various settings, software, etc. using an update program received from the terminal device 10.

Note that the terminal device 10 may communicate with the ophthalmological apparatus 1 via an Internet line. For example, if radio waves cannot reach between the terminal device 10 and the ophthalmological apparatus 1, signals may be transmitted and received over the Internet. In this way, the examiner may remotely operate the ophthalmologic apparatus 1 by using the terminal device 10 and the Internet line.

Note that the control unit 70 may change the arrangement of the icons 21 displayed on the display unit 75. For example, as shown in FIG. 10, the control unit 70 may move the display position of the icon 21 on the icon screen 20 based on the examiner's operation such as a drag operation. Thereby, the examiner can change the arrangement of the icons according to the layout of the ophthalmological apparatus 1 in the examination room, and can easily understand the correspondence between the apparatus and the icons.

Further, the control unit 70 may display the icon 21 using an arbitrary image as a background. For example, the control unit 70 may superimpose the icon 21 on a layout image depicting walls, partitions, desks, etc. of a room. Thereby, the examiner can easily understand the correspondence between the ophthalmological apparatus 1 displayed on the display section 75 and the ophthalmological apparatus 1 in the examination room. Of course, the control unit 70 may superimpose the icon 21 on an image taken by a camera (not shown) provided in the terminal device 10.

Note that each ophthalmologic apparatus 1 may include a notification section. For example, the notification unit may indicate to the subject or the examiner that measurement/photography will be performed from now on, or may notify the examiner of a measurement/photography error or the occurrence of an abnormality in the ophthalmologic apparatus 1. For example, the notification section may be the above-mentioned indicator light 8, display section 7a, audio output section 9a, etc. For example, the notification unit may cause the indicator light 8 to turn on or blink, cause the screen of the display unit 75 to flash or change its color, or output audio using the audio output unit 9a. Good too. Further, the notification unit may notify the subject or examiner of the measurement order, the start of measurement, etc. by displaying a number indicating the measurement order on the display unit 7a.

Note that even if the ophthalmological apparatus 1 detects the presence of the subject's face or eyes E, the screens of the ophthalmological apparatus 1 and the terminal device 10 are automatically activated to enable measurement and operation. good. For example, the ophthalmologic apparatus 1 may detect the presence of the subject's face or eyes based on a light reception signal from a light reception element provided in the optometry department. Further, for example, the ophthalmologic apparatus 1 may detect the presence of the subject's face or eyes E using a sensor provided in the face support section 4.

Note that after the inspection of each ophthalmological device 1 is completed, all the acquired data may be displayed as a list, or necessary test results and analysis results may be calculated and displayed from all the data. Further, the data acquired by the ophthalmologic apparatus 1 may be transferred to another ophthalmologic apparatus 1 and the data may be used for measurement of the ophthalmologic apparatus 1 or the like. For example, the control unit 70 may transfer the AR value measured by the eye refractive power measuring device to a refractor, or may transfer the axial length measured by the axial length measuring device to an optical tomography device or the like. It's okay. In this way, by using measurement data acquired by other devices, faster and more reliable measurements can be made.

Note that in the case of a device that requires detailed analysis, the terminal device 10 may transfer the measurement data acquired by the ophthalmological device 1 to another PC. Then, the terminal device 10 may acquire the analysis result of the PC and display it on the display unit 75. Of course, the measurement data may be directly transferred from the ophthalmologic apparatus 1 to the PC. In this case, the terminal device 10 may acquire the measurement data and analysis results via the PC.

Note that the terminal device 10 may transfer the data of each ophthalmological device 1 to an electronic medical record, a filing system, etc., or may cooperate with the data.

Note that the terminal device 10 may include a photographing section 80. The control unit 70 may transmit an image (for example, the examiner's face, body, etc.) photographed by the photographing unit 80 to the ophthalmological apparatus 1 . The control unit 7 may display the image photographed by the photographing unit 80 on the display unit 7a facing the subject. This allows the examiner to explain to the subject using gestures.

Further, the ophthalmological apparatus 1 may transmit an image (for example, the subject's face, etc.) photographed by the observation optical system 2a or the like to the terminal device 10. The control section 70 may cause the display section 75 to display the image photographed by the observation optical system 2a. This allows the examiner to monitor the subject.

Note that while the examinee is sitting on a chair in front of the apparatus, an image of the examiner from the photographing unit 80 (such as the examinee's face) is displayed on the display unit 7a facing the examinee. An image (such as the subject's face) taken by the observation optical system 2a may be displayed on the display section 75 of the subject. This allows the examiner and patient to communicate by voice while viewing each other's images. For example, the examiner can explain the test to the examinee, and the examinee can ask questions to the examiner.

Note that the device may automatically detect that the subject is sitting in front of the device and enter the active state. For example, the results of light reception by the optical sensor or the optometry section 2 may be used.
