Description

[Technical Field]

[0001] The present disclosure relates to ophthalmic devices. [Background technology]

[0002] There is known an ophthalmic device that includes a base unit and an ocular information acquisition unit that is movably supported on the base unit and acquires ocular characteristics of the subject's eye, in which an operator grasps an operating lever to manually move the ocular information acquisition unit relative to the base unit and align the ocular information acquisition unit with the subject's eye (see, for example, Patent Document 1). However, manual ophthalmic devices require skilled techniques for fine alignment.

[0003] On the other hand, an ophthalmic device has also been disclosed in which an electric lever is provided on the base section for aligning the eye information acquisition section with respect to the subject's eye, and a drive mechanism is driven based on an operation signal from this electric lever to automatically control the movement of the eye information acquisition section (see Patent Documents 2 and 3).

[0004] However, ophthalmic devices that automatically control the movement of the information acquisition unit have the problem that they do not provide the same operational feel as manual devices, and are therefore not preferred by experienced optometrists, doctors, etc. Furthermore, the ophthalmic device described in Patent Document 2 can be used by removing the electric lever together with the sensor, but because the electric lever is tilted in mid-air, it is difficult for the operator to control the movement of the eye information acquisition unit as intended. Furthermore, Patent Document 3 discloses a technology that allows the controller holder to be attached to the left or right side of the ophthalmic device, but this does not improve the operability of the electric lever.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Example 1 An ophthalmic apparatus according to a first embodiment will be described below with reference to the drawings. First, the configuration of the ophthalmic apparatus 10 according to the first embodiment will be described with reference to FIGS. 1 to 3. In the following description, the X-axis, Y-axis, and Z-axis are defined as shown in each drawing. As viewed from a subject facing the ophthalmic apparatus 10, the left-right direction is defined as the X-axis direction, the up-down direction (vertical direction) is defined as the Y-axis direction, and the front-rear direction, which is perpendicular to the left-right and up-down directions, is defined as the Z-axis direction. Furthermore, since an examiner typically operates the ophthalmic apparatus 10 while facing the subject facing the ophthalmic apparatus 10 on the opposite side of the ophthalmic apparatus 10, in the left-right direction (X-axis direction), the left side of the examiner facing the subject is defined as the left direction, and the right side of the examinee is defined as the right direction. Furthermore, in the front-rear direction (Z-axis direction), the examiner side is defined as the front direction, and the subject side is defined as the rear direction.

[0011] The ophthalmic device 10 of Example 1 can be an ophthalmic device (auto-refractor) that can perform, for example, subjective tests such as distance tests, near tests, contrast tests, and glare tests, and objective measurements such as objective refraction measurement and corneal shape measurement.

[0012] It should be noted that the ophthalmic device to which the present disclosure is applied is not limited to an autorefractometer. The ophthalmic device may also be an optotype display device, a refractor head, an ophthalmoscopic device equipped with an optotype display device or a refractor head, other subjective examination devices, an objective refraction measurement device, a corneal shape measurement device, a fundus photography device, an axial length measurement device, an intraocular pressure measurement device, an axial length measurement device, an endothelial cell measurement device, a slit lamp, an optical coherence tomography (OCT) device, a scanning laser ophthalmoscope (SLO), or the like.

[0013] 1, the ophthalmologic apparatus 10 of the first embodiment includes a base unit 11, a face support unit 12, a main body unit 20, an electric drive mechanism 13, an electric lever unit 30 having an electric lever 31, and a control unit 14. As shown in FIG. 2, the ophthalmologic apparatus 10 also includes a monitor unit 15, a communication unit 16, and a memory unit 17. The drive mechanism 13, the control unit 14, the communication unit 16, and the memory unit 17 are housed in the main body unit 20.

[0014] The face support unit 12 is provided on the rear (subject side) of the upper surface of the base unit 11. The face support unit 12 has a chin rest 12a and a forehead rest 12b provided on top of the chin rest 12a. The face support unit 12 can be adjusted in the vertical direction (Y-axis direction) by being moved up and down by a known moving mechanism 12c (see FIG. 2). The subject faces the ophthalmologic device 10 while sitting on a chair or the like provided in front of the ophthalmologic device 10, and undergoes an examination or the like with their chin placed on the chin rest 12a and their forehead placed against the forehead rest 12b.

[0015] The main body 20 has a stand 21 and a measurement head 22 having an eye information acquisition unit 23. The stand 21 is placed on the base 11 and is supported by the base 11 via a drive mechanism 13. The measurement head 22 is disposed on the stand 21. The eye information acquisition unit 23 is housed in the measurement head 22.

[0016] The main body 20 (the stand 21 and the measuring head 22) can be moved by the drive mechanism 13 in the left-right direction (X-axis direction), the front-back direction (Z-axis direction), and the up-down direction (Y-axis direction).

[0017] The drive mechanism 13 is a known electric drive mechanism that moves the main body 20 in the left-right direction (X-axis direction), the front-back direction (Z-axis direction), and the up-down direction (Y-axis direction). Specifically, for example, the drive mechanism 13 has an electric actuator (not shown) such as a stepping motor that generates a drive force to move the main body 20, and a transmission mechanism (not shown) that transmits the drive force generated by the electric actuator to the pedestal 21.

[0018] In the main body 20 of Example 1, the platform 21 is supported on the base 11 so as to be movable in the left-right direction (X-axis direction) and the front-back direction (Z-axis direction), i.e., the horizontal direction, and is movable in the horizontal direction by the drive mechanism 13. The measuring head 22 is supported on the platform 21 so as to be movable in the up-down direction (Y-axis direction), i.e., the vertical direction, and is movable in the vertical direction by the drive mechanism 13. However, this configuration is not limited to this. The entire main body 20, i.e., the platform 21 and the measuring head 22 may be supported on the base 11 so as to be movable in the left-right direction (X-axis direction), the front-back direction (Z-axis direction), and the up-down direction (Y-axis direction), and be movable in the horizontal and vertical directions relative to the base 11 by the drive mechanism 13.

[0019] 1, the measurement head 22 houses an ocular information acquisition unit 23, a control unit 14, a communication unit 16, a memory unit 17, etc. The measurement head 22 also houses cables and the like that connect the ocular information acquisition unit 23, the drive mechanism 13, the up-and-down movement mechanism, a sensor unit 33 of an electric lever unit 30 (described later), etc., to the control unit 14 that controls them. The measurement head 22 is provided with a monitor unit 15 consisting of a liquid crystal display or the like in front of the top of the head (examiner side). The measurement head 22 also has a ring-shaped arrangement of light sources (not shown) on the back (subject side) for illuminating the anterior segment of the subject's eye and for measuring the membrane shape.

[0020] The eye information acquisition unit 23 is a device that acquires eye information of the subject's eye. The eye information acquisition unit 23 is a known optical system for observing and photographing the subject's eye. The eye information acquisition unit 23 has an optical lens, an imaging element, etc., and is capable of observing and photographing the anterior segment, cornea, fundus, etc. of the subject's eye.

[0021] The monitor unit 15 is configured with a liquid crystal display or the like, and has a touch panel type display surface 15a on which an image of the anterior segment of the eye to be examined, operation buttons, etc. That is, the display surface 15a functions as an operation unit through which operation inputs for operating the ophthalmologic apparatus 10 are made.

[0022] The monitor unit 15 is attached to a support 15b fixed to one edge of the top of the measurement head 22 so as to be rotatable about a horizontal axis (about the X-axis or Z-axis) and a vertical axis (about the Y-axis). The monitor unit 15 is rotated about the horizontal axis and the vertical axis by a known monitor drive mechanism 18 under the control of the control unit 14. This configuration allows the display surface 15a of the monitor unit 15 to be positioned at a desired angle or direction depending on the examiner's position, posture, eye level, etc. For example, the display surface 15a can be oriented toward the front of the main body 20 as shown in FIG. 1, toward the rear of the main body 20 (toward the examinee) as shown in FIG. 4, or toward the left or right side of the main body 20 as shown in FIG. 5.

[0023] The control unit 14 controls the overall operation of the ophthalmic apparatus 10. The control unit 14 is composed of a microprocessor and the like, and has an internal memory 14a such as a RAM. The storage unit 17 is composed of a ROM, an EEPROM, a flash memory, and the like. The control unit 14 loads a program stored in the storage unit 17, for example, on the RAM of the internal memory 14a, and comprehensively controls each unit of the ophthalmic apparatus 10.

[0024] As shown in Figure 2, the control unit 14 is electrically connected to the eye information acquisition unit 23, drive mechanism 13, monitor unit 15 (and its drive mechanism), communication unit 16, memory unit 17, sensor unit 33 of the electric lever unit 30 described later, movement mechanism 12c of the face support unit 12, etc. by a cable (not shown) housed inside the main body unit 20, and is able to communicate with each other.

[0025] As a result, the control unit 14 can drive and control the ocular information acquisition unit 23, the drive mechanism 13, the moving mechanism 12c, etc., in accordance with a detection signal from the sensor unit 33 and an operation signal generated by a touch operation on the touch panel of the monitor unit 15, and can display an image of the subject's eye, etc., acquired by the ocular information acquisition unit 23, on the display surface 15a of the monitor unit 15. The control unit 14 is also connected to the electric lever 31 by wireless communication through the communication units 16 and 31b, and drives and controls the ocular information acquisition unit 23 in accordance with an operation signal from the electric lever 31 via the push button 31a.

[0026] The communication unit 16 communicates with the communication unit 31b of the electric lever 31 via wireless communication. There are no particular limitations on the wireless communication, and Wi-Fi (registered trademark), Bluetooth (registered trademark), etc. can be used. The communication unit 16 outputs an operation signal received from the communication unit 31b of the electric lever 31 to the control unit 14. In accordance with this operation signal, the control unit 14 drives and controls the eye information acquisition unit 23 to acquire eye information of the subject's eye.

[0027] The electric lever unit 30 is attached to the main body 20. As shown in FIG. 2 or 3, the electric lever unit 30 includes an electric lever 31, a support part 32, and a sensor part 33. The support part 32 and the sensor part 33 are housed in a housing 34 made of metal or the like. Hereinafter, the parts other than the electric lever 31, i.e., the support part 32, the sensor part 33, and the housing 34, will be referred to as a unit main body 35. In the first embodiment, the electric lever 31 is detachably attached to the unit main body 35 (more specifically, to the support part 32).

[0028] The electric lever 31 is an electronic device that is held by an operator such as an examiner, and is tilted or rotated to output an operation signal in response to the operation. The electric lever 31 includes a push button 31a and a communication unit 31b. The push button 31a is provided at one end (tip) of the electric lever 31. The communication unit 31b is made up of a wireless communication device, an electronic circuit, etc., and transmits an operation signal to the communication unit 16 when the examiner presses the push button 31a. The communication unit 16 outputs the received control signal to the control unit 14.

[0029] The electric lever 31 is detachably attached to the support part 32. The other end (base end) of the electric lever 31 is supported by the support part 32 so that the electric lever 31 can tilt and rotate. Therefore, the support part 32 also functions as a mounting part to which the electric lever 31 is attached. The support part 32 is provided with various sensor parts 33. The sensor part 33 is a device that detects the tilting and rotational movements of the electric lever 31. The sensor part 33 is configured with, for example, a potentiometer, a rotary encoder, etc. The potentiometer detects the tilt direction and tilt angle of the electric lever 31. The rotary encoder detects the left and right rotation direction and rotation angle of the electric lever 31 around the central axis of the electric lever 31. The sensor part 33 outputs a detection signal related to the detection result to the control part 14 via wired communication.

[0030] A plurality of unit bodies 35 are provided in the main body 20. In the second embodiment, the unit bodies 35 are provided, for example, in front of the base 21 as shown in Fig. 1, on the top of the measuring head 22 as shown in Fig. 4, on the left side of the base 21 as shown in Figs. 5 and 6, and on the right side (not shown). Each unit body 35 is embedded inside the cover member 1 that covers the main body 20.

[0031] This cover member 1 has an opening 2 on the top surface of each support part 32 so that the electric lever 31 can be attached to the support part 32 of each unit body 35. When the electric lever 31 is not attached, this opening 2 is covered with a lid body 3, making it possible to prevent the intrusion of dirt, dust, etc. into the main body part 20 and the unit body 35.

[0032] The procedure for acquiring ocular information of the subject's eye using the ophthalmologic apparatus 10 configured as described above will be described. The electric lever 31 is usually attached to a support part 32 of a unit main body 35 disposed in front of the stand 21. The monitor part 15 is disposed so that the display surface 15a faces forward (toward the examiner).

[0033] First, the subject faces the ophthalmologic apparatus 10 with his or her chin placed on the chin rest 12a and his or her forehead placed on the forehead rest 12b. The examiner is positioned in front of the ophthalmologic apparatus 10, facing the subject, and grasps the electric lever 31. The examiner then tilts the electric lever 31 back and forth and left and right to align the eye information acquisition unit 23 with the subject's eye. This tilting operation causes the sensor unit 33 to detect the tilt direction, tilt angle, rotation direction, rotation angle, etc. of the electric lever 31, and outputs detection signals to the control unit 14. The control unit 14 drives and controls the drive mechanism 13 in accordance with the detection signals. The drive mechanism 13 moves the main body unit 20 on the base unit 11 in the left and right direction (X-axis direction), front and back direction (Z-axis direction), and up and down direction (Y-axis direction).

[0034] In conventional ophthalmic devices, the examiner operates an electric lever fixed to a base or the like, and therefore the electric lever does not move in conjunction with the movement of the main body. In contrast, in the ophthalmic device 10 of Example 1, the examiner operates the electric lever 31 attached to the stand 21, and therefore the electric lever 31 and the examiner's hand holding the electric lever 31 also move together with the stand 21 (main body 20). Therefore, the examiner feels as if he or she is manually operating the electric lever 31 to move the main body 20.

[0035] Then, when the alignment is completed and the examiner presses the push button 31a, the operation signal is transmitted to the control unit 14 via the communication unit 31b and the communication unit 16. The control unit 14 drives and controls the eye information acquisition unit 23 in accordance with the operation signal, causes the unit to acquire eye information, and causes the acquired results to be displayed on the display surface 15a of the monitor unit 15. The examiner can check the acquired eye information results by visually checking the monitor unit 15.

[0036] As described above, the ophthalmic apparatus 10 of Example 1 provides an operation feel similar to manual operation when aligning the ocular information acquisition unit 23 with the electric lever 31, improving the operability of the electric lever 31 and enabling the ocular information acquisition unit 23 to be aligned with the subject's eye quickly and appropriately. As a result, the work efficiency of ocular information acquisition can be improved, such as shortening the examination time. Furthermore, the ophthalmic apparatus 10 of Example 1 can be used with preference by experienced optometrists, doctors, and the like who are accustomed to using manual ophthalmic apparatuses.

[0037] The drive mechanism 13 is an electric drive mechanism that is driven under the control of the control unit 14. Therefore, even if an operation other than the operation of the electric lever 31 occurs, specifically, if the examiner pushes the main body 20 with his / her hand or if an unintended pushing force is applied to the main body 20 due to a collision or the like, the drive mechanism 13 will not be driven, and the main body 20 will not move unexpectedly.

[0038] Furthermore, in conventional ophthalmic devices in which the electric lever is fixed, the cable connecting the electric lever and the main body moves as the main body moves, and may rub against other components, resulting in wear, breakage, etc. In contrast, in the ophthalmic device 10 of Example 1, the electric lever unit 30 including the electric lever 31 and the cable connecting the electric lever unit 30 and the control unit 14 move together with the main body 20, so the cable does not move unexpectedly and wear and breakage of the cable can be appropriately suppressed. Furthermore, in Example 1, the operation signal of the push button 31a is transmitted to the control unit 14 via wireless communication, which also reduces the number of cables.

[0039] Incidentally, there are cases where the examiner performs an examination while assisting the examinee, for example, by standing behind the examinee and holding the examinee's eyelids open with one hand. In this case, if the electric lever 31 and the monitor unit 15 are located in front of the ophthalmologic apparatus 10 as shown in Figure 1, it is difficult for the examinee to operate or view them.

[0040] Therefore, the examiner removes the electric lever 31 attached to the stand 21 and attaches it to the support part 32 of the unit body 35 provided on the top of the head of the measuring head 22. This allows the examiner to operate the electric lever 31 from behind (on the subject's side) the subject.

[0041] Furthermore, the examiner operates the monitor unit 15 to drive the monitor drive mechanism 18 under the control of the control unit 14, thereby rotating the monitor unit 15 around the X axis so that the display surface 15a faces backward (toward the subject) as shown in Fig. 4. This allows the examiner to operate the electric lever 31 while viewing the monitor unit 15 from the subject side.

[0042] Furthermore, the ophthalmic apparatus 10 of the first embodiment allows the examiner to perform operations such as acquiring eye information while positioned on the right or left side of the ophthalmic apparatus 10. Such a situation may occur, for example, when the ophthalmic apparatus 10 is installed along a wall in a corner of a room, making it impossible to operate the ophthalmic apparatus 10 from the front, facing the subject. For example, when operating the ophthalmic apparatus 10 from the left side, the examiner attaches the electric lever 31 to the support part 32 of the unit main body 35 provided on the left side of the stand 21, as shown in FIGS. 5 and 6. This allows the examiner to operate the electric lever 31 from behind (on the subject's side) the subject.

[0043] Furthermore, by operating the monitor unit 15, the examiner drives the monitor drive mechanism 18 under the control of the control unit 14 to rotate the monitor unit 15 around the X axis and / or the Z axis, so that the display surface 15a faces left, as shown in Figures 5 and 6. This allows the examiner to operate the electric lever 31 on the left side of the ophthalmologic apparatus 10 while viewing the monitor unit 15.

[0044] As described above, in the ophthalmologic apparatus 10 of Example 1, the electric lever 31 is detachably attached to the main body 20 (the stand 21 and the measuring head 22). The main body 20 is provided with a plurality of attachment portions (support portions 32) to which the electric lever 31 is attached. Therefore, it is possible to easily replace only the electric lever 31. Furthermore, by replacing the electric lever 31, the examiner can operate the electric lever 31 in a desired location, whether standing or sitting. As a result, the examiner has more freedom in terms of location and posture, and the operability of the electric lever 31 is improved, thereby improving the work efficiency of obtaining eye information.

[0045] Example 2 Next, an ophthalmic apparatus 10A according to a second embodiment will be described with reference to Figures 7 to 9. The ophthalmic apparatus 10A of the second embodiment has the same basic configuration as the ophthalmic apparatus 10 of the first embodiment shown in Figure 1 and the like, except that it is provided with only one electric lever unit 30A, and the entire electric lever unit 30A is detachably attachable to the main body 20. Therefore, the same members as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and detailed description thereof will be omitted. The following description will mainly focus on configurations and operations that are different from those of the first embodiment.

[0046] 9, the electric lever unit 30A of the second embodiment includes an electric lever 31A, a support part 32, a sensor part 33, and a connector 36. The electric lever 31 includes a push button 31a, but does not include a communication part 31b that communicates wirelessly with the control part 14. The electric lever 31 differs from the electric lever 31 of the first embodiment in that it is supported by the support part 32 in an undetachable manner.

[0047] The support part 32 supports the electric lever 31A in a tiltable but non-detachable manner. The sensor part 33 detects the tilting and rotating operations of the electric lever 31A and the pushing operation of the push button 31a, and is configured with a potentiometer, a rotary encoder, a push button operation detection sensor, etc.

[0048] The connector 36 has a rectangular substrate 36a on which a plurality of pins 36b are provided, such as for the potentiometers (X-axis potentiometer, Z-axis potentiometer) of the sensor unit 33, for the rotary encoder (Y-axis encoder), and for the push button operation detection sensor. A pair of magnets 36c is provided on both longitudinal sides of the substrate 36a, sandwiching the plurality of pins 36b. The connector 36 and the sensor unit 33 are connected by a short cable 36d. The connector 36 is not limited to a rectangular shape, and may be round. The unit main body 35 also has a magnet 37 provided on the bottom surface of the housing 34.

[0049] Meanwhile, the main body 20 is provided with connector receptacles (sockets) 27 at multiple locations as attachment points for the electric lever unit 30A (more specifically, the connector 36). The connector receptacles 27 are provided, for example, at the front, left, and right sides of the stand 21, and at the top of the measuring head 22 (see the reference numerals 27 indicated by dashed lines in Figures 7 and 8). Each connector receptacle 27 is rectangular and made of metal, or has a magnet attached, so that it can be connected to the connector 36 by magnetic force. Each connector receptacle 27 is also electrically connected to the control unit 14 by a cable (not shown), so that it can transmit a detection signal from the sensor unit 27.

[0050] The main body 20 also has a recess 4 formed by recessing a portion where the electric lever unit 30A is to be installed. The recess 4 is made of metal or is provided with a magnet. By accommodating the electric lever unit 30A (mounting portion) in the recess 4, the mounting position of the electric lever unit 30A is uniquely determined, allowing for stable placement, and the connector 36 and the connector receptacle 27 can be appropriately positioned and easily connected. Furthermore, since the connector 36 and each connector receptacle 27 are rectangular and connected by magnetic force, the position and direction of the connector 36 when mounted on the connector receptacle 27 (main body 20) are uniquely determined. In other words, the recess 4, connector 36, and connector receptacle 27 function as positioning portions that determine the mounting position of the electric lever unit 30A (electric lever 31A) relative to the main body 20.

[0051] The positioning portion is not limited to these, and as a modified example, for example, the connector 36 and the connector receiving portion 27 may be provided with male and female concave and convex shapes, or a positioning pin may be provided.

[0052] In the ophthalmic apparatus 10A of the second embodiment, the electric lever 31A is also attached to the main body 20, and therefore, when the examiner operates the electric lever 31A, the electric lever 31A moves together with the main body 20. This allows the examiner to feel an operation similar to manual operation, improves operability, enables quick and appropriate alignment work, and improves the work efficiency of obtaining eye information using the ophthalmic apparatus 10A.

[0053] Furthermore, since the connector receptacles 27, which serve as attachment portions for the electric lever unit 30A, are provided in multiple locations, the electric lever 31A together with the electric lever unit 30A can be attached to a desired position on the main body 20. This improves the examiner's freedom of location and posture, as well as the operability of the electric lever 31, thereby further improving the work efficiency of acquiring eye information. Furthermore, since the electric lever unit 30A, which is connected to the control unit 14 by a cable via the connector 36 and the connector receptacle 27, also moves together with the main body 20, wear and tear due to friction on the cable can be appropriately suppressed. Furthermore, since only one electric lever unit 30A is required, the cost of the ophthalmic apparatus 10A can be reduced.

[0054] Furthermore, the ophthalmic device 10A of Example 2 is provided with the shapes of the connector 36 and the connector receiving portion 27, the arrangement of the magnets 36c and 37, and positioning portions such as the recess 4, so that the electric lever unit 30A can be attached and detached to and from the main body portion 20 easily and accurately with a single touch, and the attachment stability is also improved.

[0055] Furthermore, in the ophthalmologic apparatus 10 of Example 2, the electric lever unit 30A having the electric lever 31A is attached to and detached from the main body 20, eliminating the need to attach and detach the electric lever 31A itself. This improves the support stability of the support part 32 of the electric lever 31A and properly maintains the support position. Therefore, the sensor part 33 can detect the tilting and rotating movements of the electric lever 31A with higher accuracy. Furthermore, there is no need to provide a wireless communication device for the push button 31a.

[0056] Although the embodiments and modified examples of the present disclosure have been described in detail above with reference to the drawings, the specific configurations are not limited to these embodiments and modified examples, and design changes that do not deviate from the gist of the present disclosure are included in the present disclosure.

[0057] For example, the ophthalmic apparatus 10, 10A of each of the above-described embodiments has a plurality of attachment portions on the main body 20, and the electric lever 31 or the electric lever unit 30A can be attached and detached to any position on the main body 20. However, it is sufficient that the electric lever 31 is attached to the main body 20 and can move together with the main body 20, and the electric lever 31 or the electric lever unit 30, 30A may be fixed to one position on the main body 20 (preferably, the front of the stand 21). Even with this configuration, the examiner can obtain an operation feeling similar to manual operation, and can appropriately operate the electric lever 31 to properly align the ocular information acquisition unit 23 with the subject's eye. Furthermore, the number of parts can be reduced, making it possible to provide a low-cost ophthalmic apparatus. [Explanation of symbols]
