This involves a visual acuity recovery training device that aims to naturally heal the human eye by moving an optotype that is supposed to face the person reciprocally over a distance of several meters in front of the person through the reciprocating movement of an optotype holder. The present invention relates to a device that can be rotated at a speed that can be followed by an appropriate eye during reciprocating motion.

至つていないのが実状である。 Conventional visual acuity recovery training devices for curing pseudomyopia etc. use a printed matter, in which a large number of visual targets such as Landolt rings of various sizes are arranged linearly or circumferentially, facing the person at a certain distance. By intermittently repeating a specific visual target such as Landolt's ring and having the person gaze at it, the function of the muscles inside the eyeball, such as the ciliary muscle, is enhanced and the accommodation power of the eye is improved. There have been many attempts to strengthen and normalize this, but the reality is that none of them have been effective for the majority of people.

組込むようにした装置である。 As shown in FIGS. 1 and 2, a rail 3 several meters in length is fixed horizontally between the supports 6, 6, and wheels 7, 7, which can run along the rail 3, are installed inside. 7. Automatically control the electric motor and power transmission mechanism that drive the wheels, and the travel distance of the wheels to a fixed distance of several meters before and after the rail 3, and once the wheels have completed traveling the fixed distance, The optotype holder moving trolley 8, which is equipped with an automatic control mechanism (not shown) that automatically starts reversing its wheels after stopping for a few seconds to visually confirm the optotype, is mounted on rails. 3
The wheels 7, 7, 7 are arranged so that they can run freely in a monorail manner along the rail 3, and the wheels 7, 7, 7 are installed around the rail 3, while the upper surface of the bogie has one end edge on the extension line of the rail 3. Person 4 standing a little away from
A disc-shaped optotype holder 2 is placed in a position and direction facing the
is fixed via a bracket 9, and a pulse motor 10 whose rotation angle of the rotor is proportional to the number of pulse signals is installed at the center back of the optotype holder 2, and the rotation axis 13 is used to hold the optotype. While projecting to the front of the center of the optotype holder 2, the rotation axis thereof can be accurately stopped at a position corresponding to each vertex position mark 11 of the regular octagon attached to the front surface of the optotype holder 2 in response to a command, and The central part is formed into a ring shape so that each vertex position mark 11 of the regular octagon described above can be seen through the space inside the ring, making it easy to confirm the position, and a permanent magnet piece 12 is attached to the tip. The attached optotype mounting arm 5 is attached to the optotype holder 2
A small disc-shaped optotype substrate 14 made of iron so as to be rotatable in parallel to the front surface of the board, and furthermore, the Landolt ring optotype 1 is attached to the front surface and is fixed to the permanent magnet piece 12 by attraction. The rear surface is removably fixed to the tip of the arm 5 through the attractive force of a magnet so that the optotype substrate 14 can be exchanged freely, and the Landolt ring optotype 1 is brought to face the person 4. In addition, the pulse motor 10 is configured to automatically rotate the rotating shaft 13 of the pulse motor 10 several times for each outward and return trip at a speed that can be visually followed by a human in accordance with the reciprocating movement of the optotype holder moving cart 8. This is a device in which a drive and stop mechanism is pre-assembled into the movable cart 8.

えるようになる。 The above-mentioned device has a person 4 standing at a position slightly away from one end edge of the rail on the extension line of the rail 3, and then drives the wheels 7, 7, 7 via the above-mentioned automatic control mechanism. If the optotype holder moving trolley 8 is made to repeatedly move back and forth along the rail 3 for a fixed distance of several meters back and forth at a relatively slow speed while The Landolt ring target 1 similarly moves back and forth as shown by the solid line arrow in Figure 1, and the person 4 is made to catch up and gaze at the Landolt ring target 1 accordingly, as shown in Figure 4 (the solid line arrow indicates the line of sight). As shown in Figure 2, the human eye 21 repeats the adjustment action of changing the thickness of the crystalline lens by contraction and relaxation of the ciliary muscle inside the eyeball, and also activates the medial rectus muscle and lateral rectus muscle among the muscles outside the eyeball. By repeating the exercise of radiating (turning in) and opening (turning outward) the line of sight of both eyes, training to naturally strengthen or normalize the muscles inside and outside the eyeballs began to occur. Training to heal conditions such as myopia and neurogenic strabismus will become much more effective.

もよいことも勿論である。 In addition, the Landolt ring target 1 is the pulse motor 1
By rotating the optotype mounting arm 5 by 45 degrees by driving the optotype holder 2, it is possible to rotate the optotype holder 2 on the front surface and accurately stop it on each vertex position mark 11 of the above-mentioned regular octagon. This makes it possible to freely change the direction of the cut in the ring and make people look at the cut, making it convenient for careful vision recovery training. Of course, as mentioned above, the optotype substrate 14 itself with the optotype 1 attached can be attached to and removed from the tip of the arm 5 via magnetic force, so it is possible to replace the optotype 1 with one of a different size, or replace the optotype 1 with another size. It goes without saying that it is possible to change the direction in which the cut of the ring 1 is made without driving the pulse motor 10. Furthermore, by making the optotype attachment arm 5 branched into a plurality of parts as shown in FIG. 3, an optotype 1 can be provided at each end of the arm 5, so that visual acuity recovery training can be performed on a plurality of people at the same time. You can do it like this. In this case, however, a clear identification color 19 is attached to the front of each branch of the optotype attachment arm 5 so that when the optotype 1 is revolved, the optotype to be focused on is not confused with that of another person. It is better to leave it there.
Furthermore, it goes without saying that the optotype attachment arm 5 may not be literally arm-like as shown in FIG. 3 or as shown in FIG. 1, but may be disc-shaped. It goes without saying that the optotype may be letters or figures found in other visual acuity test charts instead of the Landolt ring. Furthermore, the optotype 1 is attached to the optotype substrate 1 fixed to the optotype mounting arm 5 as described above.
It is needless to say that it is not limited to what is attached to the optotype attachment arm 4, and may be attached directly to the front surface of the optotype attachment arm 5.

りである。 Further, as described above, the pulse motor 1 is configured to automatically rotate the rotating shaft 13 of the pulse motor 10 several times at a speed that can be visually followed by a human for each outward and return trip in accordance with the reciprocating movement of the optotype holder moving cart 8.
If the drive and stop mechanism of 0 is built into the moving cart 8 in advance, the Landolt ring target will repeat the orbital motion as shown by the broken line arrow while reciprocating as shown by the solid line arrow in Fig. 1. This means that
As shown in FIG. 5 (the solid line arrow indicates the line of sight), the human eye 21 gazing at the optotype 1 is affected by eye adjustment and convergence caused by the muscles inside and outside the eyeball due to the aforementioned reciprocating movement of the optotype. In addition to the accommodative and divergent actions, the superior rectus, inferior rectus, inferior oblique, and superior oblique muscles, which are not involved in ocular accommodation, convergence, and divergence among the muscles outside the eyeball, The turning action of the gaze is performed repeatedly, and therefore, it has the remarkable effect of making it possible to easily carry out training that exercises all the internal and external muscles of the eyeball while strengthening and normalizing their functions. It is something that becomes. In this case, although it is inconvenient to adjust the revolution angle of the optotype, the pulse motor 10
Of course, it is possible to substitute other types of electric motors.

標を持たせた程度のものにするのが好ましい。 In this case, in order to prevent the eye nerves from being overworked, the revolution of optotype 1 is reversed in the outward and return directions of the optotype, and a number of It is preferable that the pulse motor 10 is driven and stopped by a control command from a microcomputer built into the trolley 8. For example, on the outward journey, the pulse motor 10 rotates around the visual target 1 for exactly 2 revolutions or 3 revolutions. The position of the optotype 1 in front of the optotype holder 2 after the revolution is not changed, but for the return trip, the optotype 1 is
The cut position (direction) of the Landolt ring target is automatically changed with each reciprocation by advancing the revolution angle from 45 degrees to 90 degrees (that is, one vertex or two vertices of the regular octagon). You may adopt such methods as appropriate. Furthermore, in this case, the revolution of the optotype 1 takes place at a radius that is not very large, so providing too many optotypes on the front surface of the optotype holder 2 as shown in FIG. It is not preferable when the orbital speed of the optotype is high because it can easily be confused with other targets. Therefore, in such a case, the optotype mounting arm 5 should be moved around the rotating shaft 13 of the pulse motor as shown by the two-dot chain line in FIG. It is preferable to have a linear shape extending to both sides, and to have at most one optotype at each end.
