Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sight test means is provided, and can improve vision and detect precision, can stop again testee and practice fraud, and effectively guarantees accuracy and fairness that vision detects.
Task of the present utility model is achieved through the following technical solutions, its construction features is that casing 1 front surface is provided with several sighting target display screens 3 from top to bottom successively, the number of sighting target display screen 3 is identical with the line number of visual acuity chart, each sighting target display screen 3 shows that the size of sighting target conforms to the vision numerical value that the outer side box body 1 front surface correspondence position of each sighting target display screen 3 is provided with, during use, several sighting target display screens 3 can not a plurality ofly be opened simultaneously, can only an independence open; Casing 1 front surface is provided with photographic head 4, speaker 5, Mike 6, casing 1 side is provided with switch 7, USB interface 8, control circuit board 13, storage device 14, chargeable lithium battery 15 are installed in casing 1, photographic head 4, Mike's 6 wires connect storage device 14, sighting target display screen 3, storage device 14, speaker 5, USB interface 8, switch 7 wires connect control circuit board 13, and control circuit board 13 is electrically connected to chargeable lithium battery 15; Digiplex 2 is provided with display screen 9, sighting target change key 10, options button 11, acknowledgement key 12; Digiplex 2 is connected through radio communication device with the control circuit board 13 in casing 1.
Sighting target display screen 3 is for once only showing the display screen of a sighting target.
The height of sighting target display screen 3 can show according to it size variation of sighting target.
Sighting target display screen 3, display screen 9 are LCDs.
Good effect of the present utility model is: reasonable in design, meet people and detect custom, be convenient to people and immediately understand detection case, simple, convenient, medical worker only needs hand-hold wireless remote controller just can give directions sighting target to carry out vision detection, facilitates medical worker to control understanding testing process, and give directions clear, there will not be because indication problem affects detection accuracy, improved vision and detected precision, the sighting target of sighting target display screen is random display, anyone can not understand the open condition that shows sighting target in advance, photographic head obtains tested people and ambient condition information, Mike obtains tested people's voice messaging, control circuit board can be compared tested people's voice answer of obtaining and current demonstration sighting target, produce testing result, avoided the error of artificial comparison, and the image information of Test Field, voice messaging and comparison result all can be stored in storage device for people's verification, effectively having avoided tested people not stand in the assume another's name situation of generation inspection of nominative testing position probing and normal visual acuity people occurs, malpractices have been stopped, accuracy and fairness that vision detects have effectively been guaranteed.
