  Further, when the examiner A grips the grip portion 6 in this way, the operation button 7 is arranged at the position of the index finger or the like. Therefore, it is possible to easily press the operation button 7 with the index finger while firmly holding the grip portion 6 with a finger or palm. Then, when the examiner A holds the optical scanning ophthalmoscope 100 from the front with respect to the subject eye E of the subject B and puts it on the forehead of the subject B on the forehead support 9, the subject's eye of the subject B is examined. The eyepiece tube portion 3 is arranged close to E (see FIG. 3). In addition, since the examiner A holds the optical scanning ophthalmoscope 100 in this way, the support portion 8 comes into contact with the back of the examiner A's hand or the upper surface of the upper arm, so that fundus photography can be performed while supporting the weight of the apparatus body 1 with the upper arm. It can be carried out.

  Next, when the examiner A presses the operation button 7 with an index finger or the like, fundus imaging by the laser scanning optical system 200 is started. The examiner A can operate the operation button 7 in a state where the grasping portion 6 is stably grasped by the finger other than the index finger and the entire palm. In the laser scanning optical system 200, the fundus photographing of the subject B can be performed by the optical operation as described above. As described above, by using the hand-held optical scanning ophthalmoscope 100 according to the first embodiment, the examiner A can easily and easily shoot the fundus of the subject B.

(Self-shooting mode)
Next, the self-photographing mode will be described. First, an operation when switching from the other person photographing mode as shown in FIG. 6 to the self photographing mode will be described. In the positional relationship between the apparatus main body 1 and the support 2 in the other person photographing mode, when the eyepiece tube portion 3 is brought close to the eye E of the examiner A himself, the operation button 7 of the grasping portion 6 moves to the examiner A It arrange | positions toward the direction (front) which faces, and the support part 8 is arrange | positioned toward the direction (back) opposite to the examiner A. Therefore, if the grip part 6 is gripped, the support part 8 cannot be supported by the upper arm. In addition, the examiner A operates the operation button 7 with the thumb away from the grip portion 6, and the stability of the optical scanning ophthalmoscope 100 at the time of photographing is lowered, and smooth photographing may not be performed. Or the wrist is bent, the grasping portion 6 is grasped from the back side of the operation button 7, and the operation button 7 is operated with an index finger or the like.

  Therefore, in order to perform self-photographing easily and stably, in the first embodiment, the optical scanning ophthalmoscope 100 is provided with the position setting unit 10 as described above. In order to switch to the self-photographing mode, first, as shown in FIG. 6, the examiner A detaches the support portion 8 of the support 2 from the mounting surface 5 of the apparatus main body 1, and the apparatus main body 1 and the support 2. And are separated. Next, the apparatus main body 1 is rotated by 180 ° with the rotation axis X being an axis that intersects the optical axis L of the laser scanning optical system 200 and is parallel to the protruding direction (vertical direction) of the grip 6. In the first embodiment, for example, as shown in FIGS. 5 to 7, the axis passing through the position where the center of the support portion 8 and the optical axis L intersect is the rotation axis X. However, it is only necessary that the apparatus main body 1 or the support body 2 can be rotated 180 ° in the horizontal direction in the separated state, and the position where the center of the support portion 8 and the optical axis L intersect does not necessarily have to be the rotation axis. . In this state, the support portion 8 is mounted on the mounting surface 5 while being rotated 180 ° from the initial position, and the apparatus main body 1 and the support body 2 are connected.

  When the examiner A grasps the grasping portion 6 with fingers or palm by the above operation, the support portion 8 is disposed above the arm of the examiner A, and the index finger of the examiner A is disposed on the operation button 7 (FIG. 4). Moreover, as shown in each figure of FIG. 4, FIG. 7, the eyepiece cylinder part 3 is arrange | positioned toward the direction (back) which faces the examiner A. FIG. Further, since the support portion 8 is disposed above the upper arm of the examiner A, the examiner A can support the weight of the apparatus main body 1 with the back of the hand or the upper arm even in the self-photographing mode. Also in this case, since the support body 2 is positioned on the right side of the apparatus main body 1, the apparatus main body 1 is positioned on the right hand side of the examiner A. Therefore, not only the support portion 8 but also the lower surface of the apparatus body 1 hits the right arm of the examiner A, and the weight of the apparatus body 1 can be easily supported by the right arm. When the examiner A operates with the left hand, the mounting position of the support portion 8 on the apparatus main body 1 may be changed.

  Then, when the examiner A presses the operation button 7 with an index finger or the like while holding the optical scanning ophthalmoscope 100 with respect to his / her eye E, the laser scanning optical system 200 can capture a fundus image. Done. Further, when switching from the self-photographing mode to the other-person photographing mode again, the apparatus main body 1 and the support body 2 are separated, the apparatus main body 1 is rotated by 180 ° with respect to the support body 2, and then the apparatus main body 1 and By simply connecting the support 2 to each other, the mode can be easily switched.

In other words, the relative position of the optical system with respect to the examiner A) can be changed to switch between the other person photographing mode and the self photographing mode. Therefore, the examiner A stably operates the operation button 7 by grasping the grip 6 in both the other person photographing mode for photographing the fundus of the subject B and the self photographing mode for photographing his own fundus. Operability is improved. Further, by supporting the own weight of the apparatus main body 1 with the upper arm via the support portion 8, the stability of the apparatus main body 1 is improved, and camera shake and the like can be suppressed. Therefore, in the optical scanning ophthalmoscope 100 according to the first embodiment, more accurate fundus photographing can be performed in both the other person photographing mode and the self photographing mode, and the optical performance is improved.

(Example 2)
Hereinafter, the hand-held optical scanning ophthalmoscope of Example 2 will be described with reference to FIG. The optical scanning ophthalmoscope 110 according to the second embodiment has the same basic configuration as the optical scanning ophthalmoscope according to the first embodiment except that the position setting unit 10 is changed to a position setting unit using a shaft support described later. ing. Therefore, the same code | symbol is attached | subjected to the member similar to Example 1, and detailed description is abbreviate | omitted. FIGS. 8A and 8B show changes when the optical scanning ophthalmoscope 110 according to the second embodiment is rotated. FIG. 8A shows an initial state (other person photographing mode), and FIG. 8B shows an initial state. FIG. 8C shows a state rotated by 90 ° counterclockwise (second other photographing mode), and FIG. 8C shows a state rotated by 180 ° from the initial state (self-photographing mode).

  As shown in FIGS. 8A and 8B, the optical scanning ophthalmoscope 110 according to the second embodiment includes an apparatus main body 1 including a laser scanning optical system and a control circuit unit similar to those in the first embodiment, an operation button 7, and a grip. And a support body 2 provided with a portion 6, a support portion 8 and the like. In the first embodiment, the apparatus main body 1 and the support body 2 are formed so as to be separable, and the mounting direction of the support section 8 on the mounting surface 5 is changed, whereby the eyepiece tube section 3 of the apparatus main body 1 with respect to the support body 2 is changed. A position setting unit 10 for changing the position is configured.

  On the other hand, in the second embodiment, the apparatus main body 1 and the support body 2 are rotatably supported by a support shaft (rotary shaft member) arranged coaxially with the rotation axis X orthogonal to the optical axis L. (Hereinafter referred to as “shaft support 11”). The shaft support portion 11 constitutes the position setting portion 10. That is, the position of the eyepiece tube portion 3 (optical system) relative to the examiner A is changed by relatively rotating the apparatus main body 1 and the support body 2 with the shaft support portion 11 as a fulcrum (rotation axis). Yes. 8, the shaft support portion 11 is represented by a solid line. However, since the shaft support portion 11 is actually provided between the lower surface of the apparatus body 1 and the upper surface of the support body 2, , Is not visible.

  In the first embodiment, the apparatus main body 1 can be rotated 180 ° in the horizontal direction with respect to the support 2.

As described above, since photographing at a 90 ° position (left and right sides) is possible, it is not necessary for the examiner A to photograph from the front of the subject B, and the fundus photographing of the subject B by the examiner A is performed. The degree of freedom can be further increased.

  Further, after the position is set by rotating 90 ° or 180 ° in this manner, a locking means or the like may be provided so that the apparatus main body 1 does not rotate with respect to the support 2 unnecessarily. For example, a protrusion that protrudes up and down is provided on the lower surface of the apparatus main body 1, and when the support 2 is rotated, the protrusion is retracted so that the rotation movement is not hindered. Then, when the rotational movement is completed, the protrusion protrudes and engages with the support 2 so as to exhibit the function of stopping rotation. Alternatively, mutual rotation may be suppressed by using frictional force between the apparatus main body 1 and the support body 2 or fixing means such as a magnet member when the position is not set.

The position is set so that the eyeglass tube section 3 faces rightward. With this arrangement, when the examiner A grasps the grasping portion 6, the eyepiece tube portion 3 is arranged facing the examiner A in the lateral direction (left side of the examiner A). . Therefore, the examiner A can perform fundus photography without changing his / her posture on the subject B who is not on the front but on the left side. Further, it is not necessary for the patient sitting on the bed or the like to get on the bed and to set up the optical scanning ophthalmoscope 110 from above the patient, and light is applied to the patient's eye E from the side of the bed. The scanning ophthalmoscope 110 can be easily set up. Further, even if the apparatus main body 1 is disposed sideways with respect to the examiner A as described above, the orientation of the support 2 with respect to the examiner A does not change. Therefore, the operation button 7 is disposed at a position (the position of the index finger) that is easy to be operated by the examiner A when the grasping portion 6 is grasped, and fundus photographing can be performed with good operability.

  Then, the apparatus main body 1 is further rotated, and the position of the apparatus main body 1 is arranged at a position 180 ° from the initial position, as shown in FIG.
