Abstract
The utility model relates to an optometer, which belongs to the technical field of medical instruments. The optometer is composed of a remote controller, a host machine and a visual target screen, wherein the remote controller provided with a switch, a visual target selection key and a visual target direction confirm key controls the host machine through a remote sensing technique; the host machine composed of electronic components is provided with a printer of which the upper part is connected with the visual target screen. The utility model has the advantages that the operation of specialized technical personnel is not needed, the deviation due to the unstable instruction time of visual targets is avoided and the fraud phenomenon due to the fixed position of the visual target direction is avoided.
Description
Affiliated technical field
This utility model belongs to technical field of medical instruments, and concrete is a kind of vision tester for eyesight.
Background technology
There is following deficiency in existing examination of visual acuity equipment: 1. need the professional and technical personnel to assist operation, waste time and energy; 2. sighting target is neglected the long weak point of neglecting instruction time, and anthropic factor is bigger to eyesight testing result's accuracy influence; 3. the direction fixed-site of sighting target is constant, and the experimenter remembers easily, causes the eyesight testing result inaccurate.
Summary of the invention
For overcoming the deficiency of present examination of visual acuity equipment, this utility model provides a kind of vision tester for eyesight, and it does not only need professional and technical personnel's assistance to cooperate, and the time length unanimity of sighting target indication, and sighting target can occur at random, and direction is unfixing.
Technical scheme
The technical scheme that its technical problem that solves this utility model adopts is: vision tester for eyesight is made up of remote controller, main frame and sighting target screen, and remote controller, main frame are made up of electronic devices and components, and main frame is equipped with mini-printer, and its top connects a sighting target screen.
The beneficial effects of the utility model are, can reduce professional and technical personnel's work, avoid sighting target to neglect the long short deviation that causes of neglecting instruction time, stop the cheating phenomenon that is caused by sighting target direction fixed-site.
Description of drawings
This accompanying drawing is a structural representation of the present utility model.Among the figure: 1, remote controller, 2, switch, 3, the sighting target options button, 4, sighting target direction acknowledgement key, 5, main frame, 6, printer, 7, the sighting target screen.
The specific embodiment
Remote controller 1 is provided with switch 2, sighting target options button 3 and sighting target direction acknowledgement key 4; Main frame 5 is provided with mini-printer 6, and its top and sighting target screen 7 connect together.During use, the experimenter is on the position of determining, hand-held remote controller 1, press switch 2 and begin test, main frame 5 is presented at 1.0 sighting targets on the sighting target screen 7 at random, if the experimenter presses sighting target direction acknowledgement key 4,5 in main frame is exported new sighting target at random, if the experimenter fails to confirm the sighting target direction 4 seconds, 5 in main frame is exported new sighting target automatically, if the experimenter is as requested by certain row vision sighting target (as 1.2), then carry out next line (1.5) eyesight testing, as fail by 1.2 sighting targets, then test finishes automatically, determine that its vision is 1.0, and print the result automatically by printer 6.
