Japanese Unexamined Patent Publication No. 2012-148030

However, the ophthalmic apparatus disclosed in Patent Document 1 has the following problems because the monitor unit is configured to be manually rotated around the vertical axis and the horizontal axis by the examiner.

That is, the subjects have various physiques, the ages of the subjects range from infants to the elderly, and the subjects with lower eyelids, the subjects with pathological eyes, and the mental illness. Various types of support are required for each subject when performing an examination using an ophthalmic device such as a subject. For this reason, the examiner supports (supports) the subject's back, holds the subject's head so that it does not move during the examination, and keeps the subject's eyelids open so that the eyelids do not lower during the examination. It is necessary to perform various actions during the examination with an ophthalmic device, such as maintaining by hand. Therefore, since the standing position and posture of the examiner are different for each examinee, there is a demand that the orientation of the display surface of the monitor unit is also different for each examinee.

In particular, when the examiner is supporting the subject, one hand of the examiner is used for this support, while the other hand visually recognizes the display surface and gives an operation instruction to the operation button. For this reason, it is troublesome to change the orientation of the display screen of the monitor unit for each change of the subject and for each different inspection.

On the other hand, since the examiner also has various physiques, different dominant arms, and a favorite operation posture, it is troublesome to change the direction of the display screen of the monitor unit every time the examiner changes. ..

Furthermore, since the standing position of the examiner may differ depending on the installation location of the ophthalmic appliance, it is troublesome to change the orientation of the display screen of the monitor unit each time the ophthalmic appliance is moved.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an ophthalmic apparatus capable of simplifying the time and effort for adjusting the position and orientation of the display surface of the monitor unit.

In order to achieve the above object, the ophthalmic apparatus of the present invention can move the base portion and the subject located in front of the base portion in a horizontal direction and a direction perpendicular to the base portion, respectively. A measurement head that is supported by the above and performs an inspection while observing the image to be inspected via an optical system, a monitor unit having a display surface capable of presenting at least an image to be inspected and an operation button image, and a top of the measurement head. It has a mounting part to which the monitor part is mounted, and the mounting part has a support part that rotatably supports the monitor part around the vertical axis and the horizontal axis, and further, the support part is mounted around the vertical axis and around the horizontal axis. A drive unit that is driven to rotate around the horizontal axis, a detection unit that detects the rotation position around the vertical axis and the horizontal axis of the support unit, and at least an examiner recognition unit that detects the direction of the examiner's face of the ophthalmologic apparatus. It is characterized by having a drive control unit that controls a drive unit so that the display surface of the monitor unit faces the direction of the examiner's face based on the detection results of the detection unit and the examiner recognition unit.

Here, the examiner recognition unit can have a sensor arranged in a room where an ophthalmic apparatus is installed. Further, the examiner recognition unit may have a sensor provided on at least one of the base unit and the measurement head. Then, this sensor can detect the electromagnetic wave radiated from the terminal held by the examiner.

Further, the examiner recognition unit can have an image pickup unit that captures the face of the examiner, and in addition, the examiner recognition unit performs face recognition of the examiner based on the image pickup result by the image pickup unit and controls the drive. As a result of face recognition by the examiner recognition unit, the unit can control the drive unit so that the display surface of the monitor unit faces the direction of the examiner's face when the face recognition is successful.

Then, the examiner recognition unit can authenticate the examiner based on the detection result of the sensor.

The ophthalmic apparatus of the present invention configured as described above includes a drive unit that rotationally drives the support portion around the vertical axis and the horizontal axis, and a detection unit that detects the rotational position of the support portion around the vertical axis and the horizontal axis. At least, the display surface of the monitor unit is directed toward the examiner's face based on the detection results of the examiner recognition unit that detects the direction of the examiner's face of the ophthalmology device and the detection unit and the examiner recognition unit. It has a drive control unit that controls the drive unit.

Therefore, since the drive control unit controls the drive unit so that the display surface of the monitor unit is directed toward the face of the examiner, the examiner does not have to manually adjust the position of the monitor unit or the direction of the display surface each time. , The position of the monitor unit and the direction of the display surface thereof are controlled and adjusted by the drive control unit. This makes it possible to simplify the time and effort for adjusting the position and orientation of the display surface of the monitor unit.

Here, since the examiner recognition unit has a sensor arranged in the room where the ophthalmologic device is installed, it is possible to uniformly drive and control the display surface of the monitor unit for the ophthalmic device installed in this room. can.

Further, since the examiner recognition unit has a sensor provided on at least one of the base unit and the measurement head, it is possible to reliably detect that the examiner has arrived in the vicinity of the ophthalmologic apparatus.

Since this sensor detects the electromagnetic wave radiated from the terminal held by the examiner, the examiner can be detected more reliably by detecting the electromagnetic wave.

Further, since the examiner recognition unit has an image pickup unit that captures the face of the examiner, the examiner can be detected more reliably based on the image pickup result of the image pickup unit. In addition, the examiner recognition unit performs face authentication of the examiner based on the image pickup result by the image pickup unit, and when the face authentication is successful as a result of the face authentication by the examiner recognition unit, the drive control unit moves the display surface of the monitor unit. Since the drive unit is controlled so as to face the examiner's face, the examiner can be detected more reliably.

Then, since the examiner recognition unit authenticates the examiner based on the detection result of the sensor, the examiner can be detected more reliably.

The storage unit 58 temporarily stores various data used during the control of the ophthalmic apparatus 1 by the control unit 50. Further, the storage unit 58 stores the examiner data 58a used when the examiner's face is recognized by the examiner recognition unit 50b. The examiner data 58a includes facial features of a specific examiner and the like. Preferably, the examiner data 58a is data of a plurality of examiners.

Next, the operation of the ophthalmic apparatus 1 according to the present embodiment will be described with reference to the flowchart of FIG.

The flowchart shown in FIG. 13 starts when the power of the ophthalmic appliance 1 is turned on. First, in step S1, the program stored in the internal memory 50a of the control unit 50 is executed, and the control unit 50 performs the initial setting of each unit.

Next, in step S2, based on the detection result of the detection sensor unit 55 including the motion sensor 31, the examiner recognition unit 50b determines whether or not a human (examiner) exists around the ophthalmology device 1. If the direction is detected.

Next, in step S3, the examiner recognition unit 50b detects the examiner's face and its direction based on the image pickup result of the camera unit 56 including the cameras 30a and 30b, and further, the image capture result and the storage unit of the camera unit 56. Face recognition of the examiner is performed based on the examiner data 58a stored in the examiner 58.

As for the details of the face authentication operation by the examiner recognition unit 50b, a well-known face authentication method can be suitably applied, and therefore detailed description thereof will be omitted here. As an example, the face is classified into characteristic parts, the characteristics of each part are registered in advance for each examiner, and the face is stored in the storage unit 58 as examiner data 58a. Then, the examiner recognition unit 50b may extract the above-mentioned parts from the image pickup result of the camera unit 56 and collate them with the examiner data 58a to perform face authentication.

Preferably, the drive control unit 50c executes the following steps only when the face authentication is successful as a result of the face authentication by the examiner recognition unit 50b. Naturally, face recognition is not essential in the ophthalmic apparatus 1 of the present embodiment, the examiner recognition unit 50b detects the examiner's face and its direction, and the drive control unit 50c is a subsequent step based on this detection result. May be executed.

Alternatively, after the operation of step S2, the camera unit 56 may wait until the examiner's face is recognized in step S3, and then start the face recognition operation when the examiner's face can be recognized. As a result, when the examiner is close to the ophthalmic appliance 1 to the extent that the examiner's face can be recognized, the driving operation of the attachment portion 11 after step S4 can be started.

Next, in step S4, the drive control unit 50c determines the direction of the display surface 25 of the monitor unit 10 and the position of the monitor unit 10 based on the detection results of steps S2 and S3.

The relationship between the direction of the examiner and the direction of the examiner's face with respect to the ophthalmic appliance 1 and the direction of the display surface 25 of the monitor unit 10 and the position of the monitor unit 10 can be arbitrarily determined. As an example, FIG. 14 shows. The relationship shown is mentioned.

First, as shown in FIG. 14 (a), when the subject is sitting in front of the ophthalmic appliance 1 and the examiner is standing on the right side of the ophthalmic appliance 1, as shown in FIGS. 14 (a) and 3. The display surface 25 of the monitor unit 10 is defined to face the right side of the ophthalmic appliance 1.

Next, as shown in FIGS. 14 (b) and 2, when the subject is sitting in front of the ophthalmologic device 1 and the subject is standing on the back of the subject, as shown in FIG. 14 (b). The display surface 25 of the monitor unit 10 is defined to face the front of the ophthalmic appliance 1.

Further, as shown in FIG. 14 (c), when the subject is sitting in front of the ophthalmologic device 1 and the examiner is standing on the right rear side of the ophthalmologic device 1, the monitor is as shown in FIG. 14 (c). The display surface 25 of the unit 10 is defined so as to face the right rear side of the ophthalmologic device 1. In particular, since the examiner is standing, the display surface 25 of the monitor unit 10 is determined to face slightly upward (see FIGS. 4 and 5).

Then, as shown in FIG. 14 (d), when the subject sits in front of the ophthalmic appliance 1 and the examiner also sits behind the ophthalmic appliance 1, as shown in FIGS. 14 (d) and 1. The display surface 25 of the monitor unit 10 is defined to face the rear of the ophthalmic appliance 1.

Returning to FIG. 13, in step S5, the drive control unit 50c is the vertical rotation drive unit 32 and the horizontal rotation drive unit toward the direction of the display surface 25 of the monitor unit 10 and the position of the monitor unit 10 defined in step S4. The mounting portion 11 is driven by using the driving portion 51 including the 40.

In step S6, the drive control unit 50c determines the direction of the display surface 25 of the monitor unit 10 and the position of the monitor unit 10 based on the detection results of the position detection unit 52 including the vertical rotation position detection unit 36 and the horizontal rotation position detection unit 44. Is detected.

Then, in step S7, based on the direction of the display surface 25 of the monitor unit 10 and the position of the monitor unit 10 detected in step S6, the direction of the display surface 25 of the monitor unit 10 and the monitor unit 10 defined in step S4. Whether or not the position has been reached is determined by the drive control unit 50c, and if it is determined that the position has been reached (YES in step S7), the program proceeds to step S8, and it is determined that the position has not been reached yet (NO in step S7). Then, the program returns to step S5 and continues driving the mounting portion 11.

In step S8, the control unit 50 prepares for various measurements by the measurement unit 53, in step S9, the control unit 50 starts the measurement by the measurement unit 53, waits until the measurement is completed in step S10, and when the measurement is completed, the flowchart of FIG. The operation shown in is terminated.

Preferably, even if the drive of the mounting unit 11 by the drive control unit 50c is stopped in step S8 or later and the relative positional relationship between the examiner and the ophthalmic apparatus 1 changes during the measurement work, the display surface 25 of the monitor unit 10 Does not follow this (that is, the position and direction of the display surface 25 of the monitor unit 10 are fixed).

The ophthalmic apparatus 1 according to the present embodiment configured in this way has a drive unit 51 that rotationally drives the support arm member 13d around the vertical axis and the horizontal axis, and a vertical axis rotation and a horizontal axis rotation of the support arm member 13d. Based on the detection results of the position detection unit 52 that detects the rotational position of the eye, the examiner recognition unit 50b that detects at least the direction of the examiner's face of the ophthalmic apparatus 1, and the position detection unit 52 and the examiner recognition unit 50b. It has a drive control unit 50c that controls the drive unit 51 so that the display surface 25 of the monitor unit 10 faces the direction of the examiner's face.

Therefore, since the drive control unit 50c controls the drive unit 51 so that the display surface 25 of the monitor unit 10 is directed toward the face of the examiner, the examiner changes the position of the monitor unit 10 and the direction of the display surface 25 each time. The position of the monitor unit 10 and the direction of the display surface 25 thereof are controlled and adjusted by the drive control unit 50c without manual adjustment. This makes it possible to simplify the time and effort for adjusting the position and orientation of the display surface 25 of the monitor unit 10.

Here, since the examiner recognition unit 50b has a motion sensor 31 provided on at least one of the measurement heads 3, it is possible to reliably detect that the examiner has arrived in the vicinity of the ophthalmic apparatus 1.

Since the motion sensor 31 can also detect the electromagnetic wave radiated from the terminal held by the examiner, the examiner can be detected more reliably by detecting the electromagnetic wave.

Further, since the examiner recognition unit 50b has a camera unit 56 that captures the face of the examiner, the examiner can be detected more reliably based on the image pickup result of the camera unit 56. In addition, the examiner recognition unit 50b performs face authentication of the examiner based on the image pickup result by the camera unit 56, and when the face authentication is successful as a result of the face authentication by the examiner recognition unit 50b, the drive control unit 50c monitors. Since the drive unit 51 is controlled so that the display surface 25 of the unit 10 faces the face of the examiner, the examiner can be detected more reliably.
