In this example, the door opening and closing zone detector 15 is disposed below the car floor alignment zone detector 16.
- the door opening and closing zone detector 15 has: a pair of magnetic sensors (an upper magnetic sensor 18 and a lower magnetic sensor 19) that are disposed so as to be spaced apart from each other in the direction of movement of the car 2; and a door opening and closing zone AND circuit portion (a first processing portion) 22 ( Figure 3 ) for processing information from each of the magnetic sensors 18 and 19.
- the car floor alignment zone detector 16 has: a pair of optical sensors (an upper photoelectric sensor 20 and a lower photoelectric sensor 21) that are disposed so as to be spaced apart from each other in the direction of movement of the car 2; an upper floor alignment AND circuit portion (a second processing portion) 23 ( Figure 3 ) for processing respective information from the upper photoelectric sensor 20 and the door opening and closing zone AND circuit portion 22; and a lower floor alignment AND circuit portion (a second processing portion) 24 ( Figure 3 ) for processing respective information from the lower photoelectric sensor 21 and the door opening and closing zone AND circuit portion 22.
- the upper magnetic sensor 18, the lower magnetic sensor 19, the upper photoelectric sensor 20, and the lower photoelectric sensor 21 are disposed so as to be spaced apart from each other in a single column in the direction of movement of the car 2.
- the distance between the lower magnetic sensor 19 and the lower photoelectric sensor 21 is longer than the length of the door opening and closing zone plate 13.
- the configuration is such that the upper magnetic sensor 18, the lower magnetic sensor 19, and the lower photoelectric sensor 21 are prevented from simultaneously detecting a shared door opening and closing zone plate 13.
- the distance between the upper magnetic sensor 18 and the lower magnetic sensor 19 is shorter than the length of the door opening and closing zone plate 13.
- the distance between the upper photoelectric sensor 20 and the lower photoelectric sensor 21 is shorter than the length of the car floor alignment zone plate 14.
- the upper magnetic sensor 18 and the lower magnetic sensor 19 each have a pair of facing portions that face each other in a horizontal direction.
- An upper magnetic detecting region (a first detecting region) 25 that constitutes a detecting region of the upper magnetic sensor 18 is disposed between each of the facing portions of the upper magnetic sensor 18.
- a lower magnetic detecting region (a first detecting region) 26 that constitutes a detecting region of the lower magnetic sensor 19 is also disposed between each of the facing portions of the lower magnetic sensor 19.
- the upper magnetic detecting region 25 is disposed on the upper magnetic sensor 18, and the lower magnetic detecting region 26 is disposed on the lower magnetic sensor 19.

- the shared door opening and closing zone plate 13 When the car 2 is within the door opening and closing enabled zone, the shared door opening and closing zone plate 13 is inserted into the upper magnetic detecting region 25 and the lower magnetic detecting region 26. If the position of the car 2 is too far above the door opening and closing enabled zone, the door opening and closing zone plate 13 will not be inserted into the upper magnetic detecting region 25. If the position of the car 2 is too far below the door opening and closing enabled zone, the door opening and closing zone plate 13 will not be inserted into the lower magnetic detecting region 26.
- a magnetic field is formed inside the upper magnetic detecting region 25 by the upper magnetic sensor 18.
- the upper magnetic sensor 18 detects the presence or absence of an inserted member inside the upper magnetic detecting region 25 due to magnetic flux being interrupted by the inserted member that has been inserted into the upper magnetic detecting region 25, and an internal contact performing a closing action (an On action). Consequently, the upper magnetic sensor 18 detects the presence of the inserted member only if the inserted member that has been inserted into the upper magnetic detecting region 25 is made of a magnetic material. In other words, among the door opening and closing zone plate 13 and the car floor alignment zone plate 14, the upper magnetic sensor 18 can detect only the presence or absence of insertion of the door opening and closing zone plate 13 into the upper magnetic detecting region 25.
- the contact of the upper magnetic sensor 18 opens and an off signal is output from the upper magnetic sensor 18.
- the contact of the upper magnetic sensor 18 performs the closing action (the on action), and an on signal is output from the upper magnetic sensor 18.
- the contact of the upper magnetic sensor 18 remains open, and output of the off signal from the upper magnetic sensor 18 is maintained.
- a magnetic field is formed inside the lower magnetic detecting region 26 by the lower magnetic sensor 19.
- the configuration and function of the lower magnetic sensor 19 are similar to the configuration and function of the upper magnetic sensor 18.

- the contact of the lower magnetic sensor 19 opens and an off signal is output from the lower magnetic sensor 19.

- the door opening and closing enable signal 29 is transmitted to the upper floor alignment AND circuit portion 23, the lower floor alignment AND circuit portion 24, and the control device, respectively.
- the upper photoelectric sensor 20 and the lower photoelectric sensor 21 each have a pair of facing portions that face each other in a horizontal direction.

- a lower optical detecting region (a second detecting region) 28 that constitutes a detecting region of the lower photoelectric sensor 21 is also disposed between each of the facing portions of the lower photoelectric sensor 21.
- the upper optical detecting region 27 is disposed on the upper photoelectric sensor 20, and the lower optical detecting region 28 is disposed on the lower photoelectric sensor 21.

- the shared car floor alignment zone plate 14 is inserted into the upper optical detecting region 27 and the lower optical detecting region 28. If the position of the car 2 is too far above the car floor alignment enabled zone, the car floor alignment zone plate 14 will not be inserted into the upper optical detecting region 27. If the position of the car 2 is too far below the car floor alignment enabled zone, the car floor alignment zone plate 14 will not be inserted into the lower optical detecting region 28.
- a light-emitting portion is disposed on one of the facing portions of the upper portion photoelectric sensor 20, and a light-receiving portion that receives the light from the light-emitting portion is disposed on the other facing portion.
- the upper photoelectric sensor 20 detects the presence or absence of an inserted member inside the upper optical detecting region 27 by detecting whether or not the light from the light-emitting portion has been received by the light-receiving portion. Consequently, the upper photoelectric sensor 20 detects the presence of the inserted member if the inserted member that has been inserted into the upper optical detecting region 27 is constituted by a material that interrupts the light from the light-emitting portion. In other words, the upper photoelectric sensor 20 can detect the presence or absence of both insertion of the door opening and closing zone plate 13 and insertion of the car floor alignment zone plate 14 into the upper optical detecting region 27.
- the contact of the upper photoelectric sensor 20 opens and an off signal is output from the upper photoelectric sensor 20.
- the contact of the upper photoelectric sensor 20 performs a closing action (an on action), and an on signal is output from the upper photoelectric sensor 20.
- the configuration and function of the lower photoelectric sensor 21 are similar to the configuration and function of the upper photoelectric sensor 20. Consequently, the lower photoelectric sensor 21 can detect the presence or absence of both insertion of the door opening and closing zone plate 13 and insertion of the car floor alignment zone plate 14 into the lower optical detecting region 28.
- the contact of the lower photoelectric sensor 21 opens and an off signal is output from the lower photoelectric sensor 21.

- the upper floor alignment AND circuit portion 23 outputs the upper floor alignment enable signal 30 only when the door opening and closing zone detector 15 detects that the door opening and closing zone plate 13 has been inserted into both the upper magnetic detecting region 25 and the lower magnetic detecting region 26, and the upper photoelectric sensor 20 detects that the car floor alignment zone plate 14 has been inserted into the upper optical detecting region 27.
- the lower floor alignment AND circuit portion 24 outputs a lower floor alignment enable signal 31 only when both the on signal from the lower photoelectric sensor 21 and the door opening and closing enable signal 29 are received.
- the lower floor alignment AND circuit portion 24 outputs the lower floor alignment enable signal 31 only when the door opening and closing zone detector 15 detects that the door opening and closing zone plate 13 has been inserted into both the upper magnetic detecting region 25 and the lower magnetic detecting region 26, and the lower photoelectric sensor 21 detects that the car floor alignment zone plate 14 has been inserted into the lower optical detecting region 28.
- the car floor alignment zone detector 16 detects the presence or absence of insertion of the car floor alignment zone plate 14 into the upper optical detecting region 27 and the presence or absence of insertion of the car floor alignment zone plate 14 into the lower optical detecting region 28 only when the door opening and closing zone detector 15 detects that the door opening and closing zone plate 13 has been inserted into both the upper magnetic detecting region 25 and the lower magnetic detecting region 26.
- the control apparatus is able to receive the door opening and closing enable signal 29, the upper portion floor alignment enable signal 30, and the lower portion floor alignment enable signal 31, respectively (information from the position detecting apparatus 12).
- the control apparatus determines the presence or absence of the car 2 in the door opening and closing enabled zone and the car floor alignment zone, respectively, by detecting the presence or absence of receipt of the door opening and closing enable signal 29, the upper portion floor alignment enable signal 30, and the lower portion floor alignment enable signal 31, respectively.
- the control apparatus determines that the car 2 is within the door opening and closing enabled zone if the door opening and closing enable signal 29 is being received, and determines that the car 2 is outside the door opening and closing enabled zone if receipt of the door opening and closing enable signal 29 is stopped.
- the control apparatus determines that the car 2 is within the car floor alignment zone if the door opening and closing enable signal 29, the upper portion floor alignment enable signal 30, and the lower portion floor alignment enable signal 31 are all being received.
- the control apparatus determines that the position of the car 2 is too far below the car floor alignment zone if only the upper portion floor alignment enable signal 30 is received among the upper portion floor alignment enable signal 30 and the lower portion floor alignment enable signal 31.
- the control apparatus determines that the position of the car 2 is too far above the car floor alignment zone if only the lower portion floor alignment enable signal 31 is received among the upper portion floor alignment enable signal 30 and the lower portion floor alignment enable signal 31.
- the control apparatus performs control to move the car 2 into the car floor alignment zone using the hoisting machine if the position of the car 2 is outside the car floor alignment zone when the car 2 is stopped at each building floor.
- Figure 4 is a timing chart that shows respective temporal changes of signals from each of the sensors 18 through 21, the door opening and closing enable signal 29, the upper floor alignment enable signal 30, and the lower floor alignment enable signal 31 when the car 2 from Figure 1 is ascending.
- the door opening and closing zone plate 13 is first inserted sequentially into the upper optical detecting region 27 and the lower optical detecting region 28.
- on signals are output sequentially from the upper photoelectric sensor 20 and the lower photoelectric sensor 21.
- the upper portion floor alignment enable signal 30 and the lower portion floor alignment enable signal 31 will not be output by the car floor alignment zone detector 16 because output of the door opening and closing enable signal 29 from the door opening and closing zone detector 15 is stopped. Consequently, a determination that the car 2 is within the car floor alignment zone will not be performed by the control device.
- the car 2 subsequently ascends further, and when the car 2 is stopped by control from the control device, the car floor alignment zone plate 14 is inserted sequentially into the upper optical detecting region 27 and the lower optical detecting region 28.
- on signals are again output sequentially from the upper photoelectric sensor 20 and the lower photoelectric sensor 21.
- the door opening and closing enable signal 29 is still being output from the door opening and closing zone detector 15. Consequently, the upper portion floor alignment enable signal 30 and the lower portion floor alignment enable signal 31 are output sequentially by the car floor alignment zone detector 16.
- a determination that the car 2 is within the car floor alignment zone is performed by the control device, and the floor alignment position of the car 2 is confirmed.
- the stopped position of the car 2 When the car 2 is stopped, the stopped position of the car 2 may be outside the car floor alignment zone due to passengers boarding and leaving the car 2, or expansion and contraction of the main rope that suspends the car 2, etc. In other words, a large misalignment may arise between the position of the floor of the car 2 and the position of the floor of the landing 9. If the car 2 is outside the car floor alignment zone, the stopped position of the car 2 is adjusted by control of the hoisting machine by the control device so as to be displaced to within the car floor alignment zone.
- an elevator position detecting apparatus of this kind because a door opening and closing zone plate 13 and a car floor alignment zone plate 14 that are disposed so as to be spaced apart from each other in a direction of movement of a car 2 are disposed inside a hoistway 1, and a door opening and closing zone detector 15 that can only detect the door opening and closing zone plate 13, and a car floor alignment zone detector 16 that can detect both the door opening and closing zone plate 13 and the car floor alignment zone plate 14 are disposed on the car 2, the door opening and closing zone plate 13 and the car floor alignment zone plate 14 can be detected distinctly with the door opening and closing zone plate 13 and the car floor alignment zone plate 14 arranged in a single column in the direction of movement of the car 2.
- reductions in area occupied by the position detecting apparatus 12 in a horizontal cross section of the hoistway 1 can be achieved.
- the door opening and closing zone detector 15 has a pair of magnetic sensors 18 and 19 that are disposed so as to be spaced apart from each other in the direction of movement of the car 2, the direction that the car 2 has deviated from the door opening and closing enabled zone can be determined. Consequently, adjustment of the position of the car 2 can be performed more reliably.
- the car floor alignment zone detector 16 has a pair of photoelectric sensors 20 and 21 that are disposed so as to be spaced apart from each other in the direction of movement of the car 2, the direction that the car 2 has deviated from the car floor alignment zone can be determined. Consequently, adjustment of the position of the car 2 can be performed more reliably.
- the control device can be prevented from performing an erroneous determination that the car floor alignment zone detector 16 has detected the car floor alignment zone plate 14 due to detection of the door opening and closing zone plate 13 by the car floor alignment zone detector 16.
- the door opening and closing zone plate 13 is disposed below the car floor alignment zone plate 14, but the door opening and closing zone plate 13 may also be disposed above the car floor alignment zone plate 14. In that case, the door opening and closing zone detector 15 will be disposed above the car floor alignment zone detector 16.
- the door opening and closing zone plate 13 and the car floor alignment zone plate 14 are disposed inside the hoistway 1, and the door opening and closing zone detector 15 and the car floor alignment zone detector 16 are disposed on the car 2, but the door opening and closing zone plate 13 and the car floor alignment zone plate 14 may also be disposed on the car 2 and the door opening and closing zone detector 15 and the car floor alignment zone detector 16 disposed inside the hoistway 1.
