Multiplex automatic eye-inspecting instrument itself has lighting device, therefore the not impact of climate environmental condition detects accurately, is furnished with again the slip hoodwink apparatus of examinee's special use, easy to use, the decapacitation automatic inspection is far away, outside the near vision, also can check colour vision, astigmatism, has multi-functional, energy remote control, nearly control, and the energy automatic Computer Shutdown at Fixed Time, the operator can be saved time and the labour, the departments such as hospital, clinical ophthalmology diagnosis, physical examination, optician's shop that can be used on use.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

With reference to Fig. 1, color vision graph (2), astigmatic chart (3), haplopia mark on a map (4) be printed on cellophane or the plastics, cellophane or plastics are fixed on the surface of sighting target panel (1), light source is by occulter (5), illuminating lamp (6) is formed, occulter (5) in a tubular form, available hard plastic tube or foil are made, be fixed on 502 glue on the back side of sighting target panel (1), occulter (5) is enclosed within outside the illuminating lamp (6), illuminating lamp (6) is 36 of 4.8 volts of miniature bulbs, sighting target panel (1) material is a milky white organic glass, is fixed on the case shell (7) haplopia (4) size of marking on a map, specification and international standard are far away, near vision test type is identical.

With reference to Fig. 2, changer is by ringed line plate (10), copper sheet (11), catalyst (14), support (15), toggle switch (17) constitutes, motor (9) is a slow speed motor, catalyst (14) is fixed on the change pulley (13), change pulley (13) is fixed on the support (15), support (15) is fixed on the ringed line plate (10), remote-control receiver (8), motor (9), ringed line plate (10) is fixed on the insulation board, insulation board is fixed on the case shell (7), ringed line plate (10) material is a printed substrate, 18 copper sheets (11) are arranged on the ringed line plate (10), be connected to two illuminating lamps (6) on each copper sheet (11) respectively, be respectively odd number, the even numbers numbering utilizes toggle switch (17) all lists, even numbers numbering bulb is linked to be two independently branch roads.Odd number illuminating lamp (6) is used for sighting target panel (1) top near vision sighting target, and the light source that color vision graph (2), astigmatic chart (3) are checked, even numbers illuminating lamp (6) are used for the light source of sighting target panel (1) below distant vision sighting target, and be perhaps opposite.

At this moment if up stir toggle switch (17), open remote control unit, motor (9) rotates and drives catalyst (14), contact with copper sheet (11) in turn, come conducting illuminating lamp (6), make its Automatic Cycle shinny, the near vision sighting target figure, color vision graph, the astigmatic chart that at this moment are positioned at sighting target panel (1) top will Automatic Cycle show that rightabout no longer repeats.

This device also is equipped with nearly control switch (18), general inspection colour vision, astigmatism all adopt nearly control switch (18) closely to operate, can not remote control when remote control unit is malfunctioning, also available nearly control switch (18) replaces remote control unit, reaches the effect that Automatic Cycle shows.

With reference to Fig. 3, at the inner face of case lid (20) reflective visor (22) is housed, when being used for examination of distant vision,, the operator need not walked about as long as open case lid (20), as long as be sitting in the eye-checking instrument next door, just can see examinee's gesture.

With reference to Fig. 4, it is very inconvenient to cover a glance with hands during former testing eyesight, or wear special eyeglasses, but the cost height, this hoodwink apparatus adopts elastic webbing (23), make the examinee not be subjected to the restriction of shape of face size, left and right slip hoodwink plate (24) puts this hoodwink apparatus, as long as just can reach the effect of hoodwink, easy to use, cost is low.

When using eye-checking instrument, the examinee puts on the hoodwink apparatus, and the examiner presses case lid button (21), opens case lid (20), according to your needs, stirs toggle switch (17).Timing shutdown device (19), press transmitter (26) on ﹠ off switch, after remote control receiver (8) is received signal, slow speed motor (9) is rotated, drive change pulley (13), catalyst (14) is rotated, contact with copper sheet (11) in turn, upward copper sheet (11) is contacted shinny with regard to Automatic Cycle with anastomosing one road illuminating lamp of toggle switch (17) (6) and with ringed line plate (10), as shown in Figure 2, the haplopia on the sighting target panel (1) mark on a map (4) show with regard to Automatic Cycle, when regularly finishing, timing shutdown device (19) will be cut off the electricity supply automatically, automatically shutdown.

If examinee's heavy, the demonstration time is not enough the time, press transmitter (26) on ﹠ off switch again, remote-control receiver (8) cuts off motor (9) power supply immediately, catalyst (14) is rested on the copper sheet (11) that is contacted always, so just can prolong haplopia arbitrarily and mark on a map the time that (4) show, the Push switch key then can recover Automatic Cycle again and show again.

With reference to Fig. 5, Fig. 6, transmitter (26) model is DZS-1, and transmitter (27) model is LM1871.

With reference to Fig. 7, the output signal of pulse generator (30) is controlled by YF8, connects the switch passage of remote-control receiver (28) LM1872 by a 2AP type diode

Regulated power supply (29) is LM1872 remote-control receiver (28), conversion control circuit (31), illuminating lamp (6) power supply, the emitter stage of regulated power supply (29) audion 3AX63 connects the positive source of LM1872 receiver and 16 feet of CD4017, and the colelctor electrode of audion 3AX63 meets the audion 3DG of display control circuit (32) ₁₂Colelctor electrode, display control circuit (32) is by 19 audion 3DG ₁₂(BG ₁BG ₁₉) composition, wherein 18 audion 3DG ₁₂Emitter stage be connected with illuminating lamp (6) by toggle switch (17), make 36 illuminating lamps (6) be divided into two independently branch roads, control illuminating lamp (6) by the conducting of audion and make its Automatic Cycle shinny, audion return-to-zero is used.

Utilize the tally function of CD4017 integrated circuit, conversion control circuit (31) is by two CD4017 chips, and three 74LS00 integrated packages are formed 18 cycle-counter circuits and constituted the outfan of CD4017 and audion 3DG ₁₂Base stage be connected, number of the every meter of CD4017, corresponding outfan is just exported high level, under the synergism of 74LS00 integrated package and to make other end be low level, high level can make the audion conducting, thereby the CD4017 cycle count makes audion circulation conducting.

When using eye-checking instrument, press transmitter (27) on ﹠ off switch, remote-control receiver (28) receives signal, by digital control circuit, makes toggle switch (17) institute anastomosing illuminating lamp (6) Automatic Cycle shinny, and concrete condition is same as described above not to be repeated.
