A schematic configuration of the attachment portion 11 will be described with reference to FIG. As shown in an enlarged view in FIG. 11, the attachment portion 11 has a fixed portion R fixed to the top portion 9 of the measurement head 3 (not shown in FIG. 11). The fixed portion R is generally 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 constituted by a substantially flat pedestal portion 12a and a pair of fixed plate portions 12b provided at both left and right ends of the pedestal portion 12a and extending left and right from the pedestal portion 12a. Yes.

  The fixed 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. A vertical cylindrical portion 14 whose longitudinal direction extends in the vertical direction is welded and fixed to the substantially central portion of the pedestal portion 12a 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 from the left and right ends of the horizontal plate portion 13a in the drawing. It is composed of

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

  As shown in FIG. 13, a stepped portion 14 a having a narrow diameter is formed at the upper end portion of the vertical cylindrical portion 14. A disc-shaped friction ring plate 15 is inserted into the stepped portion 14a of the vertical cylindrical portion 14 so as to sandwich the horizontal plate portion 13a of the horizontal bearing member 13 from above and below in the figure. The friction ring plate 15 and the horizontal plate A disc-shaped retaining ring member 15 ′ having a smaller diameter than the friction ring plate 15 is fitted so as to sandwich the portion 13 a.

  As a result, the horizontal plate portion 13a is supported by the step portion 14a of the vertical tube portion 14, and further, the vertical tube is receiving an appropriate downward pressure in the vertical axis 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 precisely 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.

  As shown in FIGS. 11 and 12, a support arm member 13d is attached to the pair of support plate portions 13b and 13b. The support arm member 13d has a pair of arm plate portions 13e and 13f, and a mounting bracket plate portion 13g spanning 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. On the other hand, a circular opening 13j is formed in the arm plate portion 13f located on the lower right side in FIGS.

  The horizontal shaft support portion 13h is rotated around one horizontal support shaft portion 13b, that is, the support plate portion 13b located on the upper left side in FIGS. 11 and 12, along the rotation axis along the X axis direction. It is supported so that it can move. A known torque hinge member is used for the horizontal shaft support portion 13h. This torque hinge member can adjust the rotational power around the horizontal axis.

  The other support plate portion 13b, that is, the support plate portion 13b located in the lower right portion 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. And the hollow cylinder part 19 is penetrated by these circular opening 13j, 13k as shown in FIGS. The hollow cylinder portion 19 is fixed to the other support plate portion 13b.

  Thus, the support arm member 13d is rotatable about the horizontal axis by the hollow cylindrical portion 19 and the horizontal shaft support portion 13h, and more precisely, along the rotation axis along the X-axis direction. Accordingly, the hollow shaft portion 19 and the horizontal shaft support portion 13h constitute the horizontal shaft portion H of the present embodiment. On the other hand, the support arm member 13d has a horizontal bearing member 13 that supports the support arm member 13d, which is rotated around the vertical axis by the vertical cylindrical portion 14, the friction ring plate 15 and the retaining ring member 15 ', more precisely, a rotation axis along the Z-axis direction. It can be rotated along. Accordingly, the vertical shaft portion V of the present embodiment is constituted by the vertical cylindrical portion 14, the friction ring plate 15, and the retaining ring member 15 '.

  As shown in FIG. 14, a pair of annular grooves 20, 20 are formed in the hollow cylinder portion 19 with an interval in the axial direction (longitudinal direction). C-shaped retaining rings 21 and 21 as axial retaining ring members are mounted in 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-made bearing flange member 22 is inserted into the hollow cylinder portion 19. The support arm member 13d is slidably contacted with the bearing flange member 22 so as to be rotated by receiving an appropriate force.

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

  As shown in enlarged views in FIGS. 11 and 15, the support plate portion 13b that rotatably supports the hollow cylinder portion 19 has a space around the horizontal axis, more precisely in the circumferential direction of the support plate portion 13b. A pair of protrusions 13m and 13m are formed by opening. As shown in FIG. 15, open ends 21a and 21a of the C-shaped retaining ring 21 are disposed between the protrusions 13m and 13m.

  The hollow cylinder portion 19 is configured such that the open end portions 21a and 21a of the C-shaped retaining ring 21 are disposed between the protrusion portions 13m and 13m, thereby preventing the hollow cylinder portion 19 from rotating around the horizontal axis. The durability of the portion 19 is improved.

  As shown in FIG. 11, a lead wire 16 b that electrically connects the monitor unit 10 and the measurement head 3 is drawn through the through hole 19 a of the hollow cylinder part 19 and the through hole 14 b of the vertical cylinder part 14. Thereby, the twist of the lead wire 16b accompanying rotation operation of the monitor part 10 is prevented.

  As described above, the mounting bracket plate portion 13g is disposed across the tip portions of the pair of arm plate portions 13e and 13f, as shown in FIGS. As shown in FIGS. 12, 16 and the like, a support plate 29 is attached to the mounting bracket plate portion 13g substantially parallel to the surface of the mounting bracket plate portion 13g, and further, a predetermined distance from the support plate 29. And the circuit board 23 is disposed 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 disposed on the back side of the circuit board 23, and on the front side (the back side in FIG. 16, the Y axis positive direction), FIG. 6 (b), FIG. 7 (b), FIG. 8 (a). A liquid crystal display 25j (see FIG. 21) having the display surface 25 shown in FIGS. 9 (a) and 10 (a) 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 formed by the normal of the surface of the mounting bracket plate portion 13g (right surface in FIG. 16) and the vertical surface (XZ plane) passing through the rotation axis (X axis) of the horizontal shaft portion H is an obtuse angle. Thus, the shapes of the mounting bracket plate portion 13g and the arm plate portions 13e and 13f are determined.

  And since the display surface 25 of the liquid crystal display 25j which comprises the monitor part 10 is substantially parallel with the (right) surface of the attachment bracket board part 13g, as a result, the angle which the monitor part 10 and the support arm member 13d make is an obtuse angle. It becomes. Thereby, the position change operation | work from the side which faces the examiner of the monitor part 10 to the side which faces a subject can be performed without 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 (the pair of arm plate portions 13e and 13f) about the horizontal axis. It has been. These detection sensors 25a and 25b are configured to be turned on when the display surface 25 of the monitor unit 10 is in a horizontal state and turned off when a predetermined angle is exceeded from the horizontal state, for example.

  The control circuit unit 24 cooperates with the detection sensors 25a and 25b so that the monitor unit 10 is rotated about the horizontal axis, and the display surface 25 is turned upside down before and after being turned upside down. Control is performed so that the visual position of the optometric image and the operation button image is the same, and the image information displayed on the display surface 25 is vertically and horizontally reversed.

  For example, the control circuit unit 24 controls the image information on the display surface 25 so as to be reversed vertically and horizontally when detecting the rise and fall of the output signals from the detection sensors 25a and 25b. Details of the operation button image and the eye image to be examined displayed on the display surface 25 will be described later.

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

  The lower cover member 27 includes a lower cover portion 27a, a mounting arm portion 27b, and a back cover portion 27c. The lower cover member 27 is attached to the attachment bracket plate portion 13g to the attachment arm portion 27b by an unillustrated fixing means such as a screw. 17 shows a state immediately before the lower cover member 27 is attached, and FIG. 18 shows a state after the lower cover member 27 is attached.

  As shown in FIGS. 19 and 20, a back 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 side cover member 28 has a covering portion 28 a that covers the attachment portion 11. Thereby, the back side of the circuit board 23 and the side part of the attachment part 11 are made up.

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

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

  As shown in detail in FIG. 21, the back cover member main body 28b is integrated with the support plate 29 (and the mounting bracket plate portion 13g not shown) by fixing means (not shown), while the back cover member side portion 28c, The end of 28c is fitted and integrated with the front cover frame member 26. As described above, the front side cover frame member 26 is attached to the front side of the circuit board 23 by the fixing member. 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.

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

It is attached to the top of the measuring head 3 via a rotating horizontal shaft H, and the monitor 10 is attached to the tip of the support arm member 13d so as to be movable up and down relatively with respect to the support arm member 13d. ing.

  Therefore, the rotation of the vertical shaft portion V and the horizontal shaft portion H and the vertical movement of the monitor portion 10 can increase the degree of freedom of the position of the monitor portion 10 with respect to the measurement head 3, and the measurement head 3 and the monitor for operating it. Even when integration with the unit 10 is achieved, the degree of freedom in the position of the monitor unit 10 with respect to the measurement head 3 can be improved while improving the efficiency of the position changing operation.

  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 in FIG. 9 as an example, the measurement work can be performed while the examiner is standing, and the measurement work can be performed while sitting.

  Here, since the angle formed between the monitor unit 10 and the support arm member 13d is an obtuse angle, the position changing operation from the side where the display surface 25 of the monitor unit 10 faces the examiner to the side facing the subject is obstructed. Thus, it is possible to further improve the degree of freedom of the position of the monitor unit 10 with respect to the measuring head 3 while further improving the efficiency of the position changing operation.

  The mounting portion 11 has a hollow cylindrical portion 19 that functions as a horizontal axis and a support plate portion 13b that supports the hollow cylindrical portion 19, and a support arm member 13d is provided so as to be rotatable with respect to the hollow cylindrical portion 19. The hollow cylinder portion 19 is fixed to the support plate portion 13b by a support arm member 13d by a C-shaped retaining ring 21 which is an axial retaining ring member, and the monitor portion 10 and the measurement head are passed through the through hole 19a of the hollow cylinder portion 19. 3 is electrically connected, so that 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 part to the tip of the support arm member 13d of the attachment part 11 is further increased, as shown in FIG. 6, FIG. 9, and FIG. Since the display surface 25 of the monitor unit 10 can be brought closer to the examiner, it is convenient for the operation of the touch panel.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to the embodiment and the example, and the design change is within a range not departing from the gist of the present invention. Are included in the present invention.

  As an example, as shown in FIG. 7B, the display surface 25 of the monitor unit 10 is directed to the side facing the subject and the subject fixes the face to the chin rest. A guide message such as “Please look at the target” may be displayed on the display surface 25.

  Further, in the optometry apparatus 1 according to the above-described embodiment, the eye image to be examined, the operation button image, and the display screen 25 are turned upside down before and after the monitor unit 10 is rotated around the horizontal axis. Although the image information displayed on the display surface 25 is controlled so as to be vertically and horizontally reversed so that the visual positions of the images are the same, the configuration may be omitted.
