The embodiment is not limited to the attachment position of the connection hook 35 to the base 41, the number and shape of the connection hook 35, and the like.

  Hereinafter, a case will be described in which the shapes of the two connection hooks 35 provided on the operation unit 20 are the same, but these shapes may be different from each other. At least one of the plurality of connection hooks 35 provided on the operation unit 20 may be configured as follows.

  The connection hook 35 is used to physically fix the ophthalmologic apparatus 1 and the operation unit 20 so that the operation unit 20 does not move when performing the tilting operation on the operation lever 23. In this embodiment, it is possible to restrict the movement of the operation unit 20 to which the connection hook 35 is fixed by applying the own weight of the ophthalmologic apparatus 1 to the connection hook 35. Further, by engaging the connection hook 35 with the ophthalmologic apparatus 1, it is possible to restrict the movement of the operation unit 20 to which the connection hook 35 is fixed. Hereinafter, a case will be described in which the movement of the operation unit 20 is restricted by the weight of the ophthalmologic apparatus 1 and the engagement with the ophthalmologic apparatus 1. However, the operation unit is controlled by either the own weight of the ophthalmologic apparatus 1 or the engagement with the ophthalmologic apparatus 1. The movement of 20 may be restricted.

The bottom surface of the ophthalmologic apparatus 1 may be a bottom surface of the housing of the ophthalmologic apparatus 1, a leg (including a side surface of the leg) projecting downward from the bottom, or a bottom surface of the leg. When the upper surface of the connection hook 35 contacts a part of the bottom of the housing of the ophthalmologic apparatus 1 or the like, the own weight of the ophthalmic apparatus 1 is applied to the upper surface of the connection hook 35, and the movement of the operation unit 20 is restricted.

  The connection hook 35 includes, for example, an engagement portion that engages with the ophthalmologic apparatus 1. The engaging section can be engaged with an arbitrary position of the ophthalmologic apparatus 1. In this embodiment, the engaging portion engages with a leg provided on the bottom surface of the ophthalmologic apparatus 1.

  The connection hook 35 has a penetrating region penetrating from the upper surface to the lower surface. In this embodiment, the through area is a through hole 35a into which a leg projecting downward from the bottom surface of the housing of the ophthalmologic apparatus 1 is inserted. However, the penetrating region may be any region as long as the leg provided on the bottom surface of the ophthalmologic apparatus 1 penetrates. Examples of the shape of such a penetrating region include a U-shape with an open end, a C-shape with an open right end, an inverted C-shape with an open left end, and an inverted J-shape with an open front. For example, the connection hook 35 may have a partially cut-out shape.

  At least a part of the edge of the through region is covered with the covering member 35b. The covering member 35b, as an edge protection member, prevents the leg of the ophthalmologic apparatus 1 inserted into the penetrating region from being damaged. In addition, the covering member 35b restricts the movement of the operation unit 20 by holding the leg of the ophthalmologic apparatus 1 inserted into the penetrating region as a leg holding member.

  A non-slip member 35c is provided on the lower surface of the connection hook 35. For example, the one surface of the substantially rectangular parallelepiped anti-slip member 35c and the lower surface of the distal end of the connection hook 35 are bonded to each other. The non-slip member 35c may be a member having elasticity. As such a non-slip member 35c, there is silicon rubber or the like. The lower surface (the surface opposite to the adhesive surface) of the non-slip member 35c contacts the installation surface of the operation unit 20, thereby restricting the movement of the operation unit 20.

  On the upper surface of the connection hook 35, a buffer member 35d is provided. For example, one surface of the substantially rectangular parallelepiped cushioning member 35d and the upper surface of the distal end of the connection hook 35 are bonded to each other. At least a part of the adhesive surface of the cushioning member 35d may be a surface facing the adhesive surface of the non-slip member 35c via the connection hook 35. When the upper surface (the surface opposite to the adhesive surface) of the cushioning member 35 d contacts the bottom surface of the housing of the ophthalmologic apparatus 1 in a state of being mounted on the ophthalmologic apparatus 1, the ophthalmologic apparatus 1 and the operation unit 20 are protected. I do.

  In addition, a cushioning member 36 is provided on a surface of the housing 40 facing the ophthalmologic apparatus 1 in a state of being mounted on the ophthalmologic apparatus 1. For example, one surface of the substantially rectangular parallelepiped cushioning member 36 and the above-described surface of the housing 40 are bonded to each other. When the surface opposite to the adhesive surface of the cushioning member 36 is in contact with the housing of the ophthalmic apparatus 1 while being mounted on the ophthalmic apparatus 1, the ophthalmologic apparatus 1 and the operation unit 20 are protected.
