As shown in FIG. 1, the examiner 46 seats the subject 22 on the chair 5 a in front of the optometry table 5, moves the support arm 7 up and down integrally with the column 6, and hangs on the support arm 7. The height of the optometry windows Lw and Rw of the optometry apparatus main body 4 is substantially matched with the eye height of the subject 22. It is assumed that the distance between the pupils of the subject 22 matches the distance between the optical axes of the optometry windows Lw and Rw of the optometry units 10L and 10R.

[Item: Prism separation oblique inspection mode]
When inspecting the oblique position, the chart associated with the oblique inspection is selected from the chart list 3Ca (other methods include selecting the oblique inspection from the inspection list). When the oblique inspection is executed, a control window (selection screen) 3Cd in which buttons for performing control necessary for executing the oblique inspection are collected is displayed.

  As shown in FIG. 8, the selection screen 3Cd displays “horizontal / vertical” characters (selection buttons) 3Cda and target images Ga, Gb, and Gc for guiding the direction of adding the mouse image U and the prism. The

  If a vertical prism or a horizontal prism is selected by operating the selection button 3Cda during the prism correction examination, the horizontal prism and the vertical prism arranged in the optometry window Lw and the optometry window Rw of the optometry units 10L and 10R are the vertical prism and the horizontal prism. Change to prism.

  Now, for example, when a character string chart (target chart) 100 in which numbers (characters) are arranged in a vertical row is selected by the operation unit 3a or the mouse 3b, the selected character string chart 100 is displayed on the target presentation device 2. Presented on the display unit 2b. In addition, the character string chart 100 presented on the display unit 2b of the target presentation device 2 is displayed on the monitor display unit 3Cb of the display unit 3C of the controller 3.

  On the other hand, when the character string chart 100 is selected, the controller 3 controls the driving of the pulse motors M1 to M6 of the optometry unit 10L via the CPU 45, and opts for the vertical prism 51 (see FIG. 4) of the rotating disk 28. The through-opening 30A of another rotating disk or a predetermined optical element is arranged in the optometry window Lw.

  When the vertical prism 51 is arranged in the optometry window Lw of the optometry unit 10L, the vertical prism 51 is shown in the optometry window image LwS of the optometry unit image 10LS displayed on the display unit 3C of the controller 3 as shown in FIG. A vertical prism image 51S is displayed.

  Further, the controller 3 performs drive control of the pulse motors M1 to M6 of the optometry unit 10R via the CPU 45, and arranges the through openings 30A of the rotating disks 25 to 29 and predetermined optical elements in the optometry window Rw of the optometry unit 10R. .

  When the subject 22 looks at the character string chart 100 presented on the display unit 2b of the target presentation device 2 from the optometry windows Lw and Rw of the optometry units 10L and 10R, the left and right eyes of the subject 22 are normal and oblique. If there is no place, as shown in FIG. 7, the two character strings 100A and 100B appear to be aligned in a vertical line. However, if at least one of the left and right eyes has an oblique position in the left direction, for example, the upper character string 100B appears to be shifted to the left with respect to the lower character string 100A.

  The examiner 46 asks the subject 22 how the character strings 100A and 100B look, and as shown in FIG. 7, the character string 100B is shifted to the left with respect to the character string 100A as indicated by a solid line. If there is a response that it is visible, the vertical separation image Ga and the vertical separation image Gb displayed on the selection screen 3Cd as shown in FIG. 8 correspond to the character strings 100A and 100B indicated by the solid lines in FIG. Therefore, the click button (not shown) of the mouse 3b (see FIG. 1) corresponding to the click button image Ua of the mouse image U on the side of the vertically separated images Ga and Gb is operated. Conversely, when the character string 100B is shifted to the right, the click button of the mouse 3b corresponding to the click button image Ub of the mouse image U is operated.

  By the operation of the click button corresponding to the click button image Ua, the controller 3 controls the pulse motor M5 of the optometry unit 10R, and the inspection lens (horizontal for inspection) having the minimum correction power for the horizontal oblique inspection of the rotary disk 28 is controlled. A prism) is arranged in the optometry window Rw of the optometry unit 10R. The correction power of the inspection lens is displayed on the display unit 3C of the controller 3 as an inspection result.

  When the subject 22 sees the upper character string 100B shifted to the left with respect to the lower character string 100A, the examiner 46 operates the click button of the mouse 3b again. By this operation, the controller 3 controls the pulse motor M5 of the optometry unit 10R, and arranges the inspection lens whose correction power is one step higher than the previous inspection lens in the optometry window Rw of the optometry unit 10R. In this way, the click button of the mouse 3b is operated until the upper and lower character strings 100A and 100B appear to be in a line vertically.

  The power of the inspection lens when the upper and lower character strings 100A and 100B are viewed as one line vertically is the power of the subject's horizontal oblique position, and this power is displayed on the display unit 3C.

  When the vertical prism is selected by clicking the selection button 3Cda on the selection screen 3Cd during the horizontal oblique inspection mode, the controller 3 sets the vertical oblique inspection mode and sets a character string from the chart list 3Ca of the display unit 3C. A chart (target) 101 is selected, and the character string chart 101 is displayed on the display unit 2 b of the target presentation device 2. That is, the character string chart 100 is changed to the character string chart 101.

  On the monitor display unit 3Cb of the display unit 3C, a character string chart 101 presented on the display unit 2b of the visual target presentation device 2 is displayed as shown in FIG. In addition, on the selection screen 3Cd, a mouse image U and horizontal separated images G0, G1, and G2 are displayed as shown in FIG.

  Further, the controller 3 controls the driving of the pulse motor M5 of the optometry unit 10R, and arranges the horizontal prism 50 (see FIG. 4) of the rotating disk 28 in the optometry window Rw. That is, the vertical prism 51 is changed to the horizontal prism 50.

  When the horizontal prism 50 is arranged in the optometry window Rw of the optometry unit 10R, the horizontal prism 50 is shown in the optometry window image RwS of the optometry unit image 10RS displayed on the display unit 3C of the controller 3, as shown in FIG. A horizontal prism image 50S is displayed.

  Further, the controller 3 controls the driving of the pulse motors M1 to M4 and M6 of the optometry unit 10R, and arranges the through-opening 30A of another rotating disk or a predetermined optical element in the optometry window Rw.

  When the subject 22 looks at the character string chart 101 presented on the display unit 2b of the optotype presenting apparatus 2 from the optometry windows Lw and Rw of the optometry units 10L and 10R, the left and right eyes of the subject 22 are normal and oblique. If there is no place, as shown in FIG. 10, the two character strings 101A and 101B indicated by the chain line and the solid line appear to be aligned on the left and right. However, if at least one of the left and right eyes has a downward oblique position, for example, the left character string 101B appears to be shifted downward with respect to the right character string 101A as indicated by a solid line.

  Then, the examiner 46 matches the click button image Ub of the mouse image U of the monitor display unit 3Cb shown in FIG. 11 until the left and right character strings 101A, 101B appear to be in a line on the left and right as described above. Operate the click button.

  By the operation of the click button corresponding to the click button image Ub, the controller 3 controls the pulse motor M5 of the optometry unit 10L, and the inspection lens (horizontal inspection prism) for inspecting the horizontal oblique position of the rotating disk 28 is in ascending order of frequency. To the optometry window Lw of the optometry unit 10L are sequentially arranged each time the click button is operated.

  That is, the vertical inspection prism disposed in the optometry window Rw of the optometry unit 10R is changed to the horizontal inspection prism disposed in the optometry window Lw of the optometry unit 10L.

  The power of the inspection lens when the left and right character strings 101A and 101B appear to be in a line on the left and right is the power of the oblique position in the vertical direction.

  Similarly, when the horizontal prism is selected by clicking the selection button 3Cda on the selection screen 3Cd during the vertical oblique inspection mode, the character string chart 100 is presented on the display unit 2b of the target presentation device 2 in the same manner as described above. The vertical prism 51 of the rotating disk 28 is arranged in the optometry window Lw, and the examination lens is arranged in the optometry window Rw of the optometry unit 10R.

  As described above, when the horizontal prism or the vertical prism is selected by clicking the selection button 3Cda on the selection screen 3Cd during the vertical oblique inspection mode or the horizontal oblique inspection mode, the horizontal oblique inspection mode or the vertical oblique inspection mode is set. The character string chart 100 or the character string chart 101 is presented on the display unit 2b of the optotype presenting apparatus 2, and the vertical prism 51 is provided in the optometry window Lw of the optometry unit 10L, or the horizontal prism is provided in the optometry window Rw of the optometry unit 10R. 50 and the other optometry windows Rw and Lw are arranged with inspection lenses, so switching from the horizontal oblique inspection mode to the vertical oblique inspection or from the vertical oblique inspection mode to the horizontal oblique inspection is performed. Can be carried out easily, and these oblique inspections can proceed smoothly, so that unnecessary images are presented during the inspection. Therefore, the optometry can be performed without adversely affecting the optometry.

  In the above embodiment, the character charts 100 and 101 are presented to check the oblique position. For example, as shown in FIGS. You may make it show on the display part 2b of the presentation apparatus 2, and may make it test | inspect an oblique position. It may also be a Landolt's ring vision chart.
