The minimum pupil diameter determination mark 25h is used to stop measurement when the pupil diameter is equal to or smaller than the minimum pupil diameter determination mark 25h.

  In addition to the anterior segment image being observed, images such as figures, symbols, codes, and other images as appropriate are displayed in the display region 25c for the subject eye image. In FIG. 12, the anterior segment image Gf of the subject and the measurement results S, C, and A are displayed. 12, Gf ′ is an iris image, Gf ″ is a pupil image, P1 is a corneal bright spot image, and P2 is an alignment index image.

  For example, as shown in FIG. 13, the control circuit unit 24 responds to the touch location tp when the examiner touches the display area 25c of the eye image with a finger or the like in the observation mode of the anterior eye image Gf. The measurement head 3 is driven up, down, left, and right so that the image portion to be positioned is at the screen center G0. Thereby, the pupil image Gf ″ of the eye image to be examined is controlled so as to be positioned at the center of the screen.

  For example, the control circuit unit 24 calculates a distance L on the screen from the screen center G0 to the touch location tp, and drives and controls the horizontal stepping motor and the vertical stepping motor based on the distance L. With this drive control, the measuring head 3 is moved vertically and horizontally (Z-axis direction and X-axis direction) with respect to the eye to be examined.

  Here, the control circuit unit 24 drives the stepping motor so that the measurement head 3 is driven at a high speed by the first touch and is driven at a low speed by the second touch. This is because the distance between the screen center G0 and the pupil center PDO is large at the time of the first touch, and it is desirable to drive at high speed in order to speed up the measurement. On the other hand, at the time of the second touch, the distance between the screen center G0 and the pupil center PDO is considered to be small, and the measurement head 3 is controlled so that the pupil center PDO accurately enters the target area mark 25g. This is because low-speed driving is desirable.

  When the pupil center PDO is positioned in the vicinity of the target area mark 25g and the corneal bright spot image P1 is detected, the control circuit unit 24 is based on the distance between the detected position of the corneal bright spot image P1 and the screen center G0. The measurement head 3 is automatically driven in the vertical and horizontal directions (Z-axis direction and X-axis direction), and the measurement head 3 is moved in the front-rear direction (Y-axis direction) so that the focus of the corneal bright spot image P1 is in focus. To drive. Then, when the corneal bright spot image P1 enters the target area mark 25g and the output value of the corneal bright spot image P1 exceeds a predetermined value, the measurement is automatically executed.
