Therefore, from the said zone upper end of opening the door-again the lower end 35a of lower end, contraposition zone detection zone part 35 to the regional lower end of can opening the door-length (width) of the upper end 36b of upper end, contraposition zone detection zone part 36 is suitable with the length (width) in contraposition zone 111 more again.As shown in Figure 3, this is arranged on the midway location in the zone 112 of can opening the door in contraposition zone 111 again.
Each test section is set to the corresponding relation of each detection zone part: a DZ1 test section 101A of said photoelectric position detector, 10 is used for detecting the regional detection zone part 34 of can opening the door; The 2nd DZ2A test section 102A is used for detecting contraposition zone lower end detection zone part 35, the three DZ2B test section 103A of upper end, zone-again that can open the door and is used for detecting upper end, the contraposition zone detection zone part 36 of the regional lower end of can opening the door-again.
As shown in Figure 1; When lift car 15 rises or descends; The photoelectric position detector, 10 that is arranged on the lift car 15 is arranged on the shading member 11 on each floor 16 with the optical mode detection, carries out the stop control and contraposition control again of lift car 15 thus.
In addition, carry out the control of UCMP (car accidental shifting fender guard) through CD (car door) 14 that detects the lift car side and the HD (entrance hall door) 13 that is arranged on each floor 16.
During lift car 15 risings are gone, when lift car 15 will rest in next floor, detect the shading member 11 that is arranged on the stop floor with optical mode by photoelectric position detector, 10.
Photoelectric position detector, 10 is configured to: along with the lifting action of lift car 15; When said shading member 11 relatively inserts in the hollow space 31 of inboard of photoelectric position detector, 10, detect said shading member 11 by photoelectric position detector, 10.
As shown in Figure 1, constitute specific range sensing device 12 by photoelectric position detector, 10 and shading member 11.
Below detection action when photoelectric position detector, 10 detected shading members 11 specify.
During lift car 15 risings are gone; For example as shown in figures 1 and 3; Also do not arrive under the state of shading member 11 at photoelectric position detector, 10, the detection light 30 that irradiates from first luminous element 24, second luminous element 25 and the 3rd luminous element 26 does not have crested, so each photo detector 27～29 (DZ1 test section 101A; The 2nd DZ2A test section 102A, the 3rd DZ2B test section 103A) state is respectively ON, ON and ON.
After lift car 15 further rises and makes that photoelectric position detector, 10 passes through the said lower end 34a and lower end 36a of shading member 11; The detection light 30 crested members 11 that irradiate from first luminous element 24 and the 3rd luminous element 26 cover, and do not have crested from the detection light 30 of second luminous element, 25 irradiations.
Therefore, the state variation of each photo detector 27～29 (a DZ1 test section 101A, the 2nd DZ2A test section 102A, the 3rd DZ2B test section 103A) is OFF, ON and OFF.Promptly first photo detector 27 and the 3rd photo detector 29 (a DZ1 test section 101A and the 3rd DZ2B test section 103A) detect lift car 15 and have got into and can open the door regional 112 through two photo detectors.
So; Through promptly a DZ1 test section 101A and the 3rd DZ2B test section 103A detect lift car 15 doubly and got into the zone 112 of can opening the door by two test sections; Even for example fault has taken place a side test section, also can detect by another test section.
Further rise and when making the said lower end 35a of photoelectric position detector, 10 through shading member 11 at lift car 15; The detection light 30 whole cresteds that irradiate from first luminous element 24, first luminous element 25 and the 3rd luminous element 26; Each photo detector 27～29 (DZ1 test section 101A; The 2nd DZ2A test section 102A, the 3rd DZ2B test section 103A) state is respectively OFF, OFF and OFF.So, (the 2nd DZ2A test section 102A) is the OFF state from the ON state variation according to second photo detector 28, can detect lift car 15 and get into the zone of contraposition again 111.
When behind lower end 35a (bottom in the contraposition zone again) certain distance that advanced of above-mentioned shading member 11, begin to carry out elevator and stop to handle, and stop control, make lift car 15 stop at as on the stop face 17 of stopping target.

So; After lift car 15 rests in stop face 17; Because of new passenger takes advantage of into lift car; Lift car 15 takes place sometimes descend, between the stop face 17 of lift car 15 and elevator lobby side, produce difference of height, just lift car 15 can drop to the situation of the position lower than contraposition more regional 111.At this moment, when detecting the decline of lift car 15, carrying out the control of contraposition again, make lift car aim at stop face 17 once more by second photo detector 28 (the 2nd DZ2A test section 102A).
On the other hand; After lift car 15 rests in stop face 17; If the passenger of following elevator is a lot; Lift car 15 takes place sometimes rise, between the stop face 17 of lift car 15 and elevator lobby side, produce difference of height, just lift car 15 rises to the situation of the position higher than contraposition more regional 111.At this moment, when detecting the rising of lift car 15, carry out the control of contraposition again, make lift car aim at stop face 17 once more at the 3rd photo detector 29 (the 3rd DZ2B test section 103A).
Do not stop floor and under the situation about directly rising at lift car 15; When the zone of contraposition again 111 through shading member 11 of photoelectric position detector, 10; The 3rd photo detector 29 (the 3rd DZ2B test section 103A) becomes the ON state from the OFF state; When lift car 15 further rises; Photoelectric position detector, 10 is through the upper end 34b and the upper end 35b of shading member 11, and photo detector 27 also becomes the ON state from the OFF state with photo detector 29 (a DZ1 test section 101A and the 3rd DZ2B test section 103A), can confirm that thus photoelectric position detector, 10 has passed through shading member 11.
