Abstract
The utility model relates to an eyesight testing appliance, in particular a visual acuity test chart to prevent cheating, provided with a pedestal. One side of the pedestal is equipped with two vertical shelter boards. A gap is set between these two shelter boards as an inspection area. A directing board which can be slipped up and down and positioned is equipped in the middle of the gap with the directing aperture in the board right against the gap. The pedestal after the shelter boards is equipped with an illuminant tumbler. E-shape markers are arranged in descending sequence basipetally on the surface of the tumbler. This utility model mainly solves the technical problem that the existing eyesight meter is easily used for cheating with the E-shape markers widely open so as to decrease the misunderstanding between examiners and examinees and increase the veracity of inspection results.
Description
Technical field
The vision that relates to this utility model detects apparatus, particularly a kind of visual acuity chart with the function that prevents to practise fraud.
Background technology
It is requisite project in the health check-up that vision detects.It is except confirming that those who are investigated whether the myopia, also have the effect of selecting the outstanding person of vision.The latter particularly, for as: pilot, extraordinary soldier's choice is a most key health check-up project.In case in this test item, do not accomplish strict screening, will on this work position, stay very big hidden danger from now on.
It mainly is to utilize the mode of traditional visual acuity chart to carry out that present vision detects, this visual acuity chart mainly be one on the blank sheet of paper that the detected person opens wide fully from big to small, and the E font labelling of the various directions of neatly arranging line by line from top to bottom.During detection, the doctor need to point out certain E font labelling of detected person's identification by indicating arm one end, and by the detected person by language or limbs mode Xiang the sensing that the doctor represents the E word mark, finish vision according to this and detect.But this detection mode has following defective:
1, cheating easily, because arranging of visual acuity chart can carry on the back out in advance, therefore, the situation that is easy to cheating takes place.
When 2, the doctor is by indicating arm indication certification mark, cause detected person's misunderstanding easily.Because doctor's indication action is often very fast, and also might refer in this case will cause tester and detected person's misunderstanding like this between two labellings, and then causes the deviation of testing result by mistake.
As mentioned above, existing eye chart and detection mode are still waiting to improve.
The utility model content
The purpose of this utility model provides a kind of visual acuity chart of anti-cheating, the visual acuity chart that mainly solves the existing complete open type of E font cue mark is easy to generate the technical problem of cheating, and be difficult in testing process, causing tester and detected person's misunderstanding, improved the accuracy of testing result.
For solving the problems of the technologies described above, this utility model is achieved in that
A kind of visual acuity chart of anti-cheating is characterized in that: it comprises a base, and the side on this base is provided with two shutters that vertically are provided with, and has a slit as detection zone between the shutter; One can slide up and down, localized direction board is arranged between the slit, and the indicator hole on the direction board is over against this slit; Be provided with on the base behind this shutter one can be luminous rotating cylinder, the E font labelling that this drum surface is provided with line by line down, arrange from big to small.
The visual acuity chart of described anti-cheating is characterized in that: the rotating shaft of this rotating cylinder is exactly a luminous body.
The visual acuity chart of described anti-cheating is characterized in that: the diameter of this rotating cylinder is less than the distance between shutter two outer side edges.
The visual acuity chart of described anti-cheating is characterized in that: 2-3 indicator hole of descending vertical arrangement on this direction board.
By technique scheme, the technique effect that the utlity model has is:
1, this utility model can be avoided by learning off the phenomenon of visual acuity chart cheating by the structure in rotating cylinder and slit.
2, this utility model can be avoided because the unclear misunderstanding that causes of indicating positions by the indicator hole on the direction board.
Description of drawings
Fig. 1 is Facad structure figure of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure:
The 1-base;
21,22-shutter;
The 23-slit;
The 3-direction board;
The 31-indicator hole;
The 4-rotating cylinder;

The specific embodiment
See also Fig. 1,2, it is the structural representation of the visual acuity chart of a kind of anti-cheating of this utility model.As shown in the figure: it comprises a base 1, and the side on this base 1 is provided with two shutters 21,22 that vertically are provided with, and has a slit 23 as detection zone between the shutter 21,22; One can slide up and down, localized direction board 3 is arranged between the slit 23, and the indicator hole on the direction board 3 31 is over against this slit 23; Be provided with on the base 1 behind this shutter 21,22 one can be luminous rotating cylinder 4, the E font labelling that these rotating cylinder 4 surfaces are provided with line by line down, arrange from big to small.The rotating shaft 41 of this rotating cylinder 4 is exactly a luminous body.The diameter of this rotating cylinder 4 so just can hide rotating cylinder 4 in the back less than the distance between shutter 21,22 2 outer side edges.
2-3 indicator hole 31 of descending vertical arrangement on this direction board 3.
During use, by slip direction board 3 with the indicator hole on the direction board 3 31 corresponding to the E font labelling in the slit 23.And select E font labelling by rotation rotating cylinder 4, help avoiding the generation of cheating like this.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of this utility model claim change and modification, all should be technology category of the present utility model.
