Description

The present invention relates to an optometry device capable of improving the degree of freedom in the position of a monitor unit.

It has a measurement head that is movable up, down, left, right, front and back facing the subject and performs an examination while observing the image to be inspected through an optical system, and a joystick that operates this. There is known an optometry device having a configuration in which the degree of freedom in arranging the operation / display unit with respect to the measurement head is improved by connecting the operation / display unit to the monitor unit with a cable (see, for example, Patent Document 1). ).

Further, an optometry device having a configuration in which a monitor unit can be rotated with respect to a main body unit of a controller device as an operation / display unit is also known. A touch panel is provided on the display surface of the monitor unit, and an image showing an operation button and an image of various image / character information are displayed on the display surface.

The display surface is turned to the side facing the examiner and the side facing the subject by the rotation of the monitor unit around the horizontal axis, and when it is directed to the side facing the examiner and to the subject. The image displayed on the display surface is flipped vertically and horizontally when facing the opposite side, and the position of the button before rotation and the position of the button after rotation are apparently the same. It is controlled by a control circuit at such a position (see, for example, Patent Document 2).

Further, there is also known a monitor support device of an ultrasonic diagnostic device capable of easily moving the monitor unit so that the user fits his / her own posture (see, for example, Patent Document 3). Further, there is also known an ophthalmic apparatus provided with a holding means for holding the monitor unit tiltably from a substantially vertical state to a horizontal state on the rear side of the measurement head (see Patent Document 4).

Japanese Patent No. 3676053 Japanese Unexamined Patent Publication No. 2007-68583 Japanese Unexamined Patent Publication No. 2007-37981 Japanese Patent No. 4587741

However, in the ophthalmic apparatus disclosed in Patent Document 1, since the measurement head and the operation / display unit for operating the measurement head are separately configured, the degree of freedom in arranging the monitor unit with respect to the measurement head is improved, but they are separate. It is inconvenient because it has to be carried to. In addition, it is difficult to save space, and it is inconvenient to operate from the side where the subject is.

For example, some subjects have poor eyelid opening, and for such subjects, the examiner is close to the subject to help open the eyelids, but the subject is examined. The display surface of the monitor unit cannot be seen from the side where the person is, which causes a decrease in measurement efficiency.

Therefore, by using the technique disclosed in Patent Document 2, the monitor unit and the measurement head are integrated, and the display surface of the monitor unit is directed to the side facing the subject and the side facing the examiner. It is conceivable to have a configuration that can be used.

With such a configuration, the display surface can be directed to the side facing the examiner and the side facing the subject, which is convenient to carry and saves space. The position of the monitor unit with respect to the measurement head is limited, and the degree of freedom due to the fact that the measurement head and the monitor unit are separate is reduced.

The present invention has been made in view of the above circumstances, and even when the measurement head and the monitor unit for operating the measurement head are integrated, the monitor unit for the measurement head is improved while improving the efficiency of the position change work. It is an object of the present invention to provide an optometry apparatus capable of improving the degree of freedom in the position of the eye.

In an eye examination device having a mounting portion provided on the top of the monitor and to which a monitor portion is mounted, the mounting portion has a support arm member mounted on the top of the measuring head so as to be rotatable around a vertical axis, and the monitor has a support arm member. A member extending along the vertical direction of the monitor unit is attached to the back surface of the display surface of the unit, and the tip portion of the support arm member is fitted into the member extending along the vertical direction. It is slidably supported along the extending direction of this member, and a monitor portion is attached to the tip of the support arm member so as to be relatively vertically movable with respect to the support arm member. And.

Here, the support arm member is attached to the top of the measuring head via a fixed portion fixed to the top of the measuring head, a vertical axis portion that rotates around the vertical axis, and a horizontal shaft portion that rotates around the horizontal axis. Can be configured.

Further, the mounting portion has a hollow cylinder portion that functions as a horizontal axis and a support plate that supports the hollow cylinder portion, and a support arm member is rotatably provided for the hollow cylinder portion, and the hollow cylinder portion is supported. It can be configured to be fixed to the support plate by an axial retaining ring member to the arm member, and the monitor portion and the measurement head are electrically connected to each other through a through hole of the hollow cylinder portion.

Therefore, the degree of freedom in the position of the monitor unit with respect to the measurement head can be increased by the rotation of the support arm member around the horizontal axis and the vertical movement of the monitor unit, and the measurement head and the monitor unit that operates the measurement head can be integrated. Even in this case, it is possible to improve the degree of freedom in the position of the monitor unit with respect to the measurement head while improving the efficiency of the position change work.

Here, the support arm member is attached to the top of the measuring head via a fixed portion fixed to the top of the measuring head, a vertical shaft portion that rotates around the vertical axis, and a horizontal shaft portion that rotates around the horizontal axis. Therefore, by rotating the vertical axis and the horizontal axis and moving the monitor up and down, the efficiency of the position change work is further improved, and the degree of freedom of the position of the monitor with respect to the measurement head is further improved. Can be done.

Further, the mounting portion has a hollow cylinder portion that functions as a horizontal axis and a support plate that supports the hollow cylinder portion, and a support arm member is rotatably provided for the hollow cylinder portion, and the hollow cylinder portion is supported. It is fixed to the support plate by the axial retaining ring member to the arm member, and the monitor part and the measurement head are electrically connected through the through hole of the hollow cylinder part, so that the monitor part can be connected even by the rotation of the monitor part.

It is explanatory drawing which shows the state which is directed to.

In the following description, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be simplified.

In the optometry device 1 of the present embodiment, the top 9 of the measurement head 3 is provided with a mounting portion 11 to which the monitor portion 10 is mounted, as shown in FIGS. 6 to 10.

The schematic configuration of the mounting portion 11 will be described with reference to FIGS. 11 and the like. As shown enlarged in FIG. 11, the mounting portion 11 has a fixing portion R fixed to the top portion 9 of the measurement head 3 (not shown) in FIG. The fixing portion R is roughly composed of a vertical bearing member 12 made of sheet metal and a horizontal bearing member 13 made of sheet metal.
The vertical bearing member 12 is roughly composed of a substantially flat plate-shaped pedestal portion 12a and a pair of fixing plate portions 12b provided at both left and right ends of the pedestal portion 12a and extending to the left and right from the pedestal portion 12a. There is.

The fixing plate portion 12b is fixed to the top portion 9 of the measuring head 3 by a fixing member (not shown) such as a screw. At the substantially central portion of the pedestal portion 12a, a vertical tubular portion 14 whose longitudinal direction extends in the vertical direction is welded and fixed by, for example, welding means.

As shown in FIGS. 11 and 12, the horizontal bearing member 13 includes a horizontal plate portion 13a and a pair of support plate portions 13b formed by being raised upward in the figure from the left and right ends of the horizontal plate portion 13a. It is composed of.

As shown in FIG. 12, a circular opening 13c is formed in the substantially central portion of the horizontal plate portion 13a, and the vertical tubular portion 14 is inserted into the circular opening 13c.

As shown in FIG. 13, a stepped portion 14a having a narrow diameter is formed at the upper end portion of the vertical tubular portion 14. A disk-shaped friction ring plate 15 is inserted into the step portion 14a of the vertical cylinder portion 14 so as to sandwich the horizontal plate portion 13a of the horizontal bearing member 13 from above and below in the drawing, and the friction ring plate 15 and the horizontal plate are inserted. A disk-shaped retaining ring member 15'with a diameter smaller than that of the friction ring plate 15 is fitted so as to sandwich the portion 13a.

As a result, the horizontal plate portion 13a is supported by the stepped portion 14a of the vertical cylinder portion 14, and further, the vertical cylinder portion is subjected to appropriate downward pressure in the vertical axial direction by the retaining ring member 15'and the friction ring plate 15. It is possible to rotate by receiving an appropriate force around the axis of the portion 14, more accurately, around the rotation axis along the Z-axis direction, and to maintain a stopped state at an appropriate position around the vertical axis (Z-axis). Has been done.

As shown in FIGS. 11 and 12, support arm members 13d are attached to the pair of support plate portions 13b, 13b. The support arm member 13d has a pair of arm plate portions 13e and 13f, and a mounting bracket plate portion 13g bridged to the tip portions of the arm plate portions 13e and 13f.

A horizontal shaft support portion 13h is provided on the arm plate portion 13e located on the upper left side in FIGS. 11 and 12. On the other hand, a circular opening 13j is formed in the arm plate portion 13f located on the lower right side in FIGS. 11 and 12.

The horizontal axis support 13h rotates around one horizontal axis, that is, the support plate 13b located on the upper left side in FIGS. 11 and 12, more accurately along the rotation axis along the X-axis direction. It is movably supported. A known torque hinge member is used for the horizontal shaft support portion 13h. With this torque hinge member, it is possible to adjust the rotational power around the horizontal axis.

The other bearing plate portion 13b, that is, the bearing plate portion 13b located at the lower right in FIGS. 11 and 12, is formed with a circular opening 13k having substantially the same diameter as the circular opening 13j at a position facing the circular opening 13j. ing. A hollow tubular portion 19 is inserted through these circular openings 13j and 13k as shown in FIGS. 11 to 13. The hollow cylinder portion 19 is fixed to the other bearing plate portion 13b.

As a result, the support arm member 13d can be rotated around the horizontal axis by the hollow cylinder portion 19 and the horizontal shaft support portion 13h, and more accurately, along the rotation axis along the X-axis direction. Therefore, the horizontal shaft portion H of the present embodiment is configured by the hollow cylinder portion 19 and the horizontal shaft support portion 13h. On the other hand, in the support arm member 13d, the horizontal bearing member 13 that supports the support arm member 13 is rotated around the vertical axis by the vertical cylinder portion 14, the friction ring plate 15 and the retaining ring member 15', and more accurately, the rotation axis along the Z-axis direction. It is possible to rotate along the line. Therefore, the vertical axis portion V of the present embodiment is configured by the vertical cylinder portion 14, the friction ring plate 15, and the retaining ring member 15'.

As shown in FIG. 14, a pair of annular grooves 20 and 20 are formed in the hollow tubular portion 19 at intervals in the axial direction (longitudinal direction). C-shaped retaining rings 21 and 21 as axial retaining ring members are mounted on the annular grooves 20 and 20, respectively. As a result, the hollow cylinder portion 19 is prevented from coming off in the axial direction with respect to the support plate portion 13b.

As shown in FIG. 14, a resin bearing flange member 22 is inserted into the hollow cylinder portion 19. The support arm member 13d is rotatably slidably contacted with the bearing flange member 22 by receiving an appropriate force.

In FIG. 14, reference numeral 13f'is a bent plate portion bent and formed on the arm plate portion 13f, a circular opening 13j is formed on the bent plate portion 13f', and the arm plate portion 13f is the bent plate portion 13f'. It is rotatably supported by the hollow cylinder portion 19 via the above.

As shown in the enlarged view of FIGS. 11 and 15, the bearing plate portion 13b that rotatably supports the hollow cylinder portion 19 is spaced in the horizontal axis direction, or more accurately, in the circumferential direction of the bearing plate portion 13b. A pair of protrusions 13m and 13m are formed by opening. As shown in FIG. 15, the open end portions 21a and 21a of the C-shaped retaining ring 21 are arranged between these protrusions 13m and 13m.

In the hollow cylinder portion 19, the open end portions 21a and 21a of the C-shaped retaining ring 21 are arranged between the protrusions 13m and 13m, so that the rotation of the hollow cylinder portion 19 in the horizontal axial direction is prevented and the hollow cylinder portion 19 is formed. The durability of the part 19 is improved.

As shown in FIG. 11, a lead wire 16b that electrically connects the monitor unit 10 and the measurement head 3 is drawn out through the through hole 19a of the hollow cylinder portion 19 and the through hole 14b of the vertical cylinder portion 14. This prevents the lead wire 16b from being twisted due to the rotation operation of the monitor unit 10.

As described above, the mounting bracket plate portion 13g is arranged so as to straddle the tip portions of the pair of arm plate portions 13e and 13f as shown in FIGS. 11, 12, and 14. As shown in FIGS. 12 and 16, a support plate 29 is attached to the mounting bracket plate portion 13g substantially in parallel with the surface of the mounting bracket plate portion 13g, and further, a predetermined distance from the support plate 29. The circuit board 23 is arranged so as to be substantially parallel to the support plate 29. The positional relationship between the support plate 29 and the circuit board 23 will be described in detail later.

A control circuit unit 24 is arranged on the back side of the circuit board 23, and FIGS. 6 (b), 7 (b), and 8 (a) are on the front side thereof (back side in FIG. 16 in the positive direction of the Y axis). , A liquid crystal display 25j (see FIG. 21) having a display surface 25 shown in FIGS. 9A and 10A is arranged substantially in parallel with the circuit board 23.

As best shown in FIG. 15, the angle formed by the mounting bracket plate portion 13g and the pair of arm plate portions 13e and 13f is an obtuse angle. More precisely, the angle between the normal of the surface (right surface in FIG. 16) of the mounting bracket plate portion 13g and the vertical surface (XX plane) passing through the rotation axis (X axis) of the horizontal axis portion H is an obtuse angle. The shapes of the mounting bracket plate portion 13g and the arm plate portions 13e and 13f are defined so as to be.

Since the display surface 25 of the liquid crystal display 25j constituting the monitor unit 10 is substantially parallel to the (right) surface of the mounting bracket plate unit 13g, the angle between the monitor unit 10 and the support arm member 13d is obtuse as a result. It becomes. As a result, the position change work of the monitor unit 10 from the side facing the examiner to the side facing the examinee can be performed without any trouble.

As shown in FIG. 11, the arm plate portion 13e and the support plate portion 13b are provided with detection sensors 25a and 25b for detecting the rotation of the monitor portion 10 (a pair of arm plate portions 13e and 13f) around the horizontal axis. Has been done. These detection sensors 25a and 25b are configured to be turned on, for example, when the display surface 25 of the monitor unit 10 is in the horizontal state, and turned off when the display surface 25 of the monitor unit 10 exceeds a predetermined angle from the horizontal state.

The control circuit unit 24 cooperates with the detection sensors 25a and 25b to rotate the monitor unit 10 around the horizontal axis, and the display surface 25 is covered before and after it is turned upside down. It is controlled so that the apparent positions of the optometry image and the operation button image are the same, and the image information displayed on the display surface 25 is flipped vertically and horizontally.

For example, when the control circuit unit 24 detects the rise and fall of the output signal by the detection sensors 25a and 25b, the control circuit unit 24 controls so that the image information on the display surface 25 is inverted vertically and horizontally. Details of the operation button image and the eye image to be inspected displayed on the display surface 25 will be described later.

As shown in FIGS. 16 to 18, a front cover frame member 26 is attached to the front side of the circuit board 23 (back side in FIG. 16 in the positive direction of the Y axis) by a fixing member (not shown) such as a screw. As a result, the peripheral portion of the circuit board 23 is decorated. Note that FIG. 16 shows the state of the front cover frame member 26 before mounting.
Further, as shown in FIGS. 17 and 18, the mounting bracket plate portion 13g of the support arm member 13d is provided with a lower cover member 27 that covers the back side and the lower side thereof.

The lower cover member 27 has a lower cover portion 27a, a mounting arm portion 27b, and a back covering portion 27c. The lower cover member 27 is attached to the mounting bracket plate portion 13g to the mounting arm portion 27b by a fixing means (not shown) such as a screw. Note that FIG. 17 shows the state immediately before the lower cover member 27 is attached, and FIG. 18 shows the state after the lower cover member 27 is attached.

As shown in FIGS. 19 and 20, a back side cover member 28 that covers the back side of the circuit board 23 is attached to the back side of the circuit board 23 by a fixing member (not shown) such as a screw.

The back cover member 28 has a covering portion 28a that covers the mounting portion 11. As a result, the back side of the circuit board 23 and the side surface portion of the mounting portion 11 are decorated.

Note that FIG. 19 shows a state before the back side cover member 28 is attached to the circuit board 23, and FIG. 20 shows a state after the back side cover member 28 is attached to the circuit board 23.

As shown in FIGS. 19 and 20, the back side cover member 28 includes a back side cover member main body 28b integrated with the covering portion 28a and a pair of back side cover member sides provided on the left and right sides of the back side cover member main body 28b. It is divided into portions 28c and 28c.

As shown in detail in FIG. 21, the back side cover member main body 28b is integrated with the support plate 29 (and the mounting bracket plate portion 13g in the figure) by the fixing means shown in the figure, while the back side cover member side portion 28c, The end of 28c is fitted to the front cover frame member 26 and integrated. As described above, the front side cover frame member 26 is attached to the front side of the circuit board 23 by a fixing member, and therefore, the back side cover member side portions 28c and 28c are integrated with the front side cover frame member 26, the circuit board 23, and the like. ing.

As shown in the enlarged view of FIG. 21, the back surface (inner surface on the support plate 29 side) near the ends of the back side cover member side portions 28c and 28c with the back side cover member main body 28b has a direction orthogonal to the paper surface of FIG. A guide member 32 extending to the surface is provided. A groove 32a is formed in the guide member 32 along the longitudinal direction thereof (that is, a direction orthogonal to the paper surface of FIG. 17), while the back side cover member main body 28b has a back surface (inner surface on the support plate 29 side). A claw portion 28d that engages with the groove 32a is formed. As a result, as shown in FIG. 21, the back side cover member side portions 28c and 28c are attached to the back side cover member main body 28b so as to be vertically movable in FIG. 21. As a result, the monitor portion 10 is attached to the tip end portion of the support arm member 13d so as to be relatively movable up and down with respect to the support arm member 13d.

In the optometry device 1 of the present embodiment configured as described above, the support arm member 13d is located on the fixed portion R fixed to the top 9 of the measuring head 3, the vertical axis portion V movable around the vertical axis, and the horizontal axis. The monitor portion 10 is attached to the top of the measuring head 3 via the rotating horizontal shaft portion H, and the monitor portion 10 is attached to the tip of the support arm member 13d so as to be relatively movable up and down with respect to the support arm member 13d. ing.

Therefore, the degree of freedom in the position of the monitor unit 10 with respect to the measurement head 3 can be increased by the rotation of the vertical axis unit V and the horizontal axis unit H and the vertical movement of the monitor unit 10, and the measurement head 3 and the monitor that operates the measurement head 3 can be increased. Even when integrated with the unit 10, it is possible to improve the degree of freedom in the position of the monitor unit 10 with respect to the measurement head 3 while improving the efficiency of the position changing work.

As an example, when the display surface 25 of the monitor unit 10 is directed to the right side of the measurement head 3 when viewed from the subject, and when the display surface 25 of the monitor unit 10 is directed to the left side of the measurement head 3, FIG. As shown as an example in FIG. 9, it is convenient because the examiner can perform the measurement work while standing and the measurement work while sitting.

Here, since the angle formed by the monitor unit 10 and the support arm member 13d is an obtuse angle, the work of changing the position of the display surface 25 of the monitor unit 10 from the side facing the examiner to the side facing the examinee is hindered. It is possible to further improve the efficiency of the position change work and further improve the degree of freedom of the position of the monitor unit 10 with respect to the measurement head 3.

Further, the mounting portion 11 has a hollow cylinder portion 19 that functions as a horizontal axis and a support plate portion 13b that supports the hollow cylinder portion 19, and a support arm member 13d is rotatably provided with respect to the hollow cylinder portion 19. The hollow cylinder portion 19 is fixed to the support arm member 13d by a C-shaped retaining ring 21 which is an axial retaining ring member, and is fixed to the support plate portion 13b. Since 3 is electrically connected, the electrical connection between the monitor unit 10 and the measurement head 3 can be ensured even by the rotation of the monitor unit 10.

Here, if the length from the base to the tip of the support arm member 13d of the mounting portion 11 is further lengthened, as shown as an example in FIGS. 6, 9, and 10, when the examiner sits down and operates. Since the display surface 25 of the monitor unit 10 can be brought closer to the examiner, it is convenient for operating the touch panel.

Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to the embodiments and examples, and the design changes to the extent that the gist of the present invention is not deviated. Is included in the present invention.

As an example, as shown in FIG. 7 (b), before the display surface 25 of the monitor unit 10 is directed to the side facing the subject and the subject fixes his / her face to the chin rest, “solid”. A guide message such as "Please look at the optotype" may be displayed on the display surface 25.

Further, in the optometry device 1 according to the above-described embodiment, the optometry image and the operation button image are displayed before the monitor unit 10 is rotated around the horizontal axis and the display surface 25 is turned upside down. The image information displayed on the display surface 25 is controlled to be vertically and horizontally inverted so that the apparent positions of the above are the same, but such a configuration may be omitted.
