  • This state shall be termed "pseudo confinement", and the passenger shall be termed a "pseudo-confined passenger”.
  • the pseudo-confinement detection means 304 detects the pseudo-confined passenger who remains in the cage without getting off (being able to get off) the cage for such a reason as having failed to get off the cage, on the basis of detection signals from the load-in-cage detection means 301 or picture-in-cage detection means 302 and the elevator running mode detection means 303.
  • Numeral 306 designates announcement issue means for issuing a getting-off prompt announcement ANE for prompting the passenger to a movement for getting off, on the basis of an announcement ringing instruction from the pseudo-confinement detection means 304.
  • Numeral 305 designates door control means, for example, door opening-and-closure means for outputting a door opening instruction signal DOI for opening the door of the elevator cage 8, in compliance with a door opening request signal DOR from the pseudo-confinement detection means 304, the announcement issue means 306 or a cage door control device (not shown).

  • a step 41 it is decided if the running cessation state of the elevator has continued for a predetermined time period (60 sec in this example).
  • the "running cessation state of the elevator” signifies a state where the elevator has fallen into a closed-door running-cessation state having no direction, or a state where the rescue running operation of causing the elevator to arrive at a refuge floor or the nearest floor has been performed at the occurrence of a disaster, and where the elevator has been thereafter brought into a closed-door running-cessation state for the sake of safety, so that a user passenger cannot use the elevator any longer.
  • the decision result of the step 41 becomes "NO"
  • the routine proceeds to a step 48, at which an ordinary running operation is continued.
  • the decision result of the step 41 becomes "YES”
  • the routine proceeds to a step 42, at which the existence or nonexistence of a passenger in the elevator cage 8 is decided.
  • it is decided, for example, if a weighing detection value is equal to, at least, a predetermined value of 30 kg.
  • the existence or nonexistence of the passenger in the elevator cage 8 is decided by the weighing detection value here, a camera may be installed in the elevator cage 8 so as to decide the existence or nonexistence of the passenger by a picture-in-cage PT, or these measures may well be combined.
  • the weighing detection value is less than the predetermined value, the decision result of the step 42 becomes "NO" with the passenger regarded as being nonexistent in the elevator cage, the routine proceeds to a step 49, at which the running cessation state is continued.
  • the routine proceeds to a step 43, at which a getting-off prompt announcement issue ANE for prompting the passenger to a movement for getting off the elevator cage is made, for example, "Please push the door opening button" is announced.
  • a getting-off prompt announcement issue ANE for prompting the passenger to a movement for getting off the elevator cage is made, for example, "Please push the door opening button” is announced.
  • a door-opening-button lamp and an illuminator in the cage are put out, they are lit up at a step 44.
  • a step 45 it is decided if the door opening button in the elevator cage 8 has been depressed.
  • the decision result of the step 45 becomes "YES”, and the routine proceeds to a step 46, at which the door of the elevator cage 8 is opened. Simultaneously, "Please get off when the door is opened” is announced at a step 47.
  • the decision result of the step 45 becomes "NO”, and if the non-depressed state of the button has continued for a predetermined time period (for example, 60 sec) is decided at a step 50. In a case where the state has not continued for the predetermined time period, the step 45 is repeated.
  • the decision result of the step 50 becomes "YES". Then, it is judged that the passenger in the elevator cage 8 is in a situation where he/she cannot perform the movement for getting off the cage, and the door of the elevator cage 8 is opened at a step 51. Simultaneously, "Boo Xn" is announced at a step 52.
  • the announcement at the step 52 is not the getting-off prompt announcement issue ANE for prompting the passenger to the movement for getting off the cage, but it is a caution announcement ANC for reporting that the passenger might be in an immobile state in the elevator cage 8, to the surrounding dwellers, etc. outside the elevator cage.
  • the elevator control apparatus is configured so as to make the getting-off prompt announcement issue which prompts the passenger having failed to get off the cage, to the movement for getting off the cage. Therefore, even in a case where the passenger has failed to escape from the cage after the elevator has arrived at the refuge floor or the nearest floor on account of the rescue running operation at the occurrence of the disaster, or the like, the apparatus has the advantage that the pseudo confinement state is avoidable. Besides, the elevator control apparatus is configured so that, even in the state where the passenger in the cage cannot get off the cage for any reason, the door may be forcibly opened when the predetermined condition has held true. Therefore, the apparatus has the advantages that the safety is enhanced more, and that a suspicious person, a child, an elderly person or the like can be prevented from staying in the cage for a long time.
