Abstract

The utility model relates to a vision inspection tester, comprising a liquid crystal display, a remote controller and a foot stand, infrared wireless transmission is carried out to the liquid crystal display and the remote controller, so as to lead the remote controller to control the liquid crystal display to display a test signing target remotely and provide vision inspection; a group of memory card reading devices are arranged inside the liquid crystal display for leading memory cards to plug externally; various chart files with different test signing targets can be stored in advance by the memory card, when the remote controller sends a test command, the test vision target of a single specific image can be generated selectively by the liquid crystal display; in addition, the shape size, direction and appearing position of the test vision target can be changed arbitrarily and randomly, therefore, testee can not learn the test vision target familiarly in advance.

Description

Vision tester

Technical field

This utility model is about a kind of vision tester design, refers to a kind of vision tester of micro computer liquid crystal especially.

Background technology

Traditional examination of visual acuity is to use a Visual acuity chart that is printed on symbol such as " E " or " C " type, is aided with manual type again and guides subject person to point out the correct direction of breach, judge the vision degree of subject person with this, but the degree of accuracy that this kind vision detects is not high.

The applicant also once filed an application a kind of wireless remote control equipment for examining vision in the Taiwan before more than ten years, it mainly comprises an indicator board, comply with international visual standards on the indicator board and be provided with " E " or " C " type symbol that survey is looked, it distributes from top to bottom, by big and little, each sighting target is all as standard correspondence as the correspondence table, but be provided with a lamp source in the back side of each sighting target, the utilization bulb is luminous by it, therefore to light corresponding sighting target, the remote controller that is provided with similar setting accordingly allowing a sighting target wherein be lighted via the signal transmission after setting with manual mode again, and then allows testee carry out vision to detect; Above-mentioned known wireless remote control equipment for examining vision because of light source needs often to upgrade to eliminate to change, assemble time-consumingly, causes and uses inconveniently, and the arrangement of sighting target and direction fix, easily by hypermnesia, so cause measurement error.

The applicant filed an application a kind of equipment for examining vision again in the Taiwan before 2 years, purpose is to provide a kind of power saving, durable, low heat and the uniform electronic examination of visual acuity instrument that throws light on, and saves volumetric spaces, makes sighting target show that more standard is clear.

Yet, take a broad view of the application of above-mentioned various Visual acuity chart or equipment for examining vision, because of the symbol chart still may suffer in advance the ripe back of the body of hypermnesia, hiding property is desirable not to the utmost so that still can't get rid of fully when detecting various malpractices may, so room for improvement is still arranged.

Summary of the invention

Main purpose of the present utility model, be to provide a kind of vision tester design, comprise a liquid crystal display, one remote controller and a foot rest, this liquid crystal display and remote controller adopt the infrared and radio transmission, make remote controller can mate the remote control liquid crystal display and show single test sighting target (symbol or figure), in order to provide vision to detect, this liquid crystal display is planted in inside in conjunction with a memory card reading device, utilize memory card to store the figure shelves of various different test sighting targets in advance in a large number, when remote controller is assigned test instruction, can choose the test sighting target that produces single special pattern in liquid crystal display, and the shape size of test sighting target, direction and occur the position all can be at random conversion arbitrarily, so testee is the ripe back of the body test of hypermnesia in advance sighting target at all, therefore can get rid of the malpractices probability when detecting fully, accurately judge the vision degree of subject person.

The specific embodiment

As shown in Figures 1 to 4, vision tester of the present utility model, it comprises a liquid crystal display 1, a foot rest 2 and a remote controller 3, wherein:

Liquid crystal display 1, it is between framework 11 and backboard 12 liquid crystal panel 13 to be set in regular turn and a circuit board 14 constitutes, the upper end of framework 11 is also buried a wireless receiver 15 underground, and side is provided with an on ﹠ off switch 111 and a supply hub 112, again, circuit board 14 is provided with one group of memory card reading device 141, and for a memory card 16 extrapolation combinations, backboard 12 lateral surface then have a slot 121;

Foot rest 2, the H shape runners 21 and one that comprises an attached roller 211 is the seat bar 22 of upright extension, this bar 22 is provided with a quick detach lock uint 23, insert combination for an expansion link 24, and make the expansion link 24 and backboard 12 slots 121 of liquid crystal display 1 plug together locking, and utilize quick detach lock uint 23, for the upright height of the frame of rapid adjustment liquid crystal display 1;

Remote controller 3, as Fig. 4, it is to adopt the infrared and radio transmission, forms the coupling remote control with this and liquid crystal display 1, makes remote controller 3 can mate remote control liquid crystal display 1 and shows single test sighting target 4, in order to the vision detection to be provided;

Form according to above-mentioned vision tester, it is at a large amount of in advance figure shelves (extremely shown in Figure 10 as Fig. 5) that store various different test sighting targets 4 of memory card 16, when remote controller 3 is assigned test instruction, can produce the test sighting target 4 of single special pattern (when not showing in liquid crystal display 1, liquid crystal display 1 is hidden state, there is not any sighting target), and kind, shape, size, the direction of test sighting target 4 and occur the position all can be at random arbitrarily conversion or jumping move, so the ripe back of the body of testee hypermnesia is fully in advance tested sighting target.

Above-mentioned remote controller 3, it comprises various function keys such as vision progression button 31, assigned direction button 32 and sighting target kind button 33, and with the button of decidable correct (zero) or wrong (*) etc., can prerequisite location survey span during use from and specify the symbol sighting target of selecting " E " type, " C " type, animal, numeral, gesture or achromatopsia figure or astigmatic figure for use, and then carry out vision by computer proposition or artificial proposition mode and detect.

Sighting target screen of the present utility model is because of adopting the concealed design of liquid crystal, so testee can't be ripe the breach or the sensing of stiffback note sighting target, and screen brightness can be remembered by micro computer, can provide adjustment in case of necessity, the various function keys of described remote controller 3 are to adopt photoelectricity touch-control sensing formula button in addition, and the fastest need touched 0.1 second, can finish choosing of sighting target, have check and reach precisely errorless effect rapidly.
