  For example, the horizontal axis rotation detection unit detects whether or not the display screen 10a of the touch panel display 10 is above the horizontal state. The horizontal axis rotation detection unit includes, for example, a light emitting unit provided on one of the arm plate 13e and the support plate 13b and a light receiving sensor provided on the other. Further, the horizontal axis rotation detection unit further includes a shielding member that can rotate around the horizontal axis O2 in conjunction with the touch panel display 10, and the shielding between the light emitting unit and the light receiving sensor whose relative positions are fixed. The member may be configured to be movable. In this case, it is possible to detect the rotation of the touch panel display 10 about the horizontal axis O2 by shielding the light from the light emitting unit by the shielding member that moves in conjunction with the touch panel display 10. The horizontal axis rotation detection unit as described above turns on a detection signal obtained by the light receiving sensor when the touch panel display 10 is in a predetermined state, and turns off the detection signal when a predetermined angle is exceeded from the predetermined state. It is comprised so that it may become.

  For example, the vertical axis rotation detection unit detects a rotation range including a position after rotation around the vertical axis O1 of the touch panel display 10 among two or more rotation ranges around the vertical axis O1. In this embodiment, the vertical axis rotation detection unit includes a position after rotation around the vertical axis O1 of the touch panel display 10 out of four rotation ranges obtained by dividing around the vertical axis O1.

  7A to 7D are explanatory diagrams of the vertical axis rotation detection unit according to the embodiment. FIG. 7A schematically illustrates the outline of the configuration of the vertical axis rotation detection unit according to the embodiment as viewed from the direction of the vertical axis O1. For convenience of explanation, the orientation of the display screen 10a of the touch panel display 10 (the orientation of the normal direction of the screen) is such that the orientation on the subject side is 180 °, and the orientation on the examiner side facing the subject is 0 °. It is assumed that the rotation angle increases counterclockwise. FIG. 7B is a cross-sectional view taken along line FF (a line connecting a 90 ° position and a 270 ° position) in FIG. 7A. 7C and 7D are explanatory diagrams of the operation of the vertical axis rotation detection unit in FIG. 7A. FIG. 7C is an operation explanatory diagram of the vertical axis rotation detection unit for each rotation around the vertical axis O1, and FIG. 7D is an operation explanatory diagram of the vertical axis rotation detection unit for each rotation range.

  The vertical axis rotation detection unit includes a sensor holding unit 15 and a shielding member 16. The sensor holding unit 15 includes a light emitting unit holding unit 15a, a light receiving sensor holding unit 15b, and a support unit 15c. On the surface of the light emitting unit holding unit 15a facing the first surface of the shielding member 16, light emitting units PS1 and PS2 are arranged at positions separated by a predetermined distance. On the surface of the light receiving sensor holding portion 15b facing the second surface opposite to the first surface of the shielding member 16, light receiving sensors PD1 and PD2 are disposed at positions separated by a predetermined distance. The light receiving sensor PD1 is provided so as to receive the light emitted by the light emitting unit PS1. The light receiving sensor PD2 is provided so as to receive the light emitted by the light emitting unit PS2.

  The support portion 15 c supports the light emitting portion holding portion 15 a and the light receiving sensor holding portion 15 b with a distance longer than the thickness of the shielding member 16. Thereby, in the sensor holding part 15, the relative position of each light emitting part and light receiving sensor is fixed. The shielding member 16 can move between each set of light emitting units and light receiving sensors around the vertical axis O1 in conjunction with the touch panel display 10. The shielding member 16 is formed with one or more slits or notches in two circumferential directions different in distance from the vertical axis O1. Such a shielding member 16 can be formed by known etching or pressing. The light emitted by the light emitting unit is received by the light receiving sensor when passing through the slit or notch of the shielding member 16, and is not received by the light receiving sensor when irradiated to portions other than the slit or notch of the shielding member 16. . As described above, it is possible to detect the rotation ranges R1 to R4 around the vertical axis O1 of the touch panel display 10 by shielding the light from the light emitting unit by the shielding member 16 that moves in conjunction with the touch panel display 10. Is possible. When the rotation angle is θ, the rotation range R1 is a range of −45 ° (315 °) <θ ≦ + 45 °. The rotation range R2 is a range of + 45 ° <θ ≦ + 135 °. The rotation range R3 is a range of + 135 ° <θ ≦ + 225 °. The rotation range R4 is a range of + 225 ° <θ ≦ + 315 °.

  For example, when the sensor holding part 15 is disposed at a 90 ° position, the detection signals obtained by the light receiving sensors PD1 and PD2 change as shown in FIGS. 7C and 7D. Thereby, based on the detection signals obtained by the light receiving sensors PD1 and PD2, it is possible to specify the rotation range including the position of the touch panel display 10 after the rotation about the vertical axis O1.

  In addition, although the case where the vertical axis rotation detection unit is provided on the subunit 30 side has been described, it may be provided on the main unit 20 side.

  In FIG. 6, although the case where the attachment part 11 was provided in the top part 9 of the measurement head 3 was demonstrated, the structure of the ophthalmologic apparatus 1 which concerns on embodiment is not limited to this. For example, a base end portion of a holding arm that can rotate around the vertical axis O <b> 1 may be provided at the top portion 9 of the measurement head 3, and a mounting portion 11 may be provided at the tip portion of the holding arm. In this case, the vertical axis rotation detection unit is configured to detect the rotation around the vertical axis O1 of the base end portion of the holding arm.
