  Next, the operation will be described with reference to the flowcharts shown in FIGS.

  For example, when a passenger using the elevator operates the car call button 13 in the elevator hall 1 on the A floor of the building (S1), the signal is sent to the control panel 30, and the car 14 is controlled by the control panel 30 based on this signal. Moves toward the elevator hall 1 on the A floor, and the light emitter 25 at the entrance 4 in the elevator hall 1 on the A floor lights up (S2). The light emitter 25 emits red light, for example.

  When the car 14 arrives at the elevator hall 1 on the A floor (S3), the light emitter 25 changes from a continuous lighting state to a blinking lighting state under the control of the control panel 30 (S4). When the light emitter 25 is blinking, the car door device 17 and the hold door device 8 are opened in conjunction with the car door device 17 under the control of the control panel 30 (S5), and the doorways 4 and 15 are opened. Passengers in the elevator hall 1 enter the car 14 through the opened entrances 4 and 15 (S6), and operate the destination floor button 21 to register the destination floor (S7). When the destination floor is registered, the hold door device 8 and the car door device 17 are closed (S8), and the entrances 4 and 15 are closed.

  After the hold door device 8 and the car door device 17 are closed, the light emitters 25 in the elevator hall 1 on the A floor are turned off (S9), and the light emitters 26 in the car 14 in which the passenger has entered are turned on (S10). . Further, when the car 14 moves toward the destination floor (S11) and the car 14 arrives at the destination floor (S12), the light emitter 26 is changed from the continuous lighting state to the blinking lighting state by the control of the control panel 30. Change (S13). When the light emitter 26 is blinking, the car door device 17 and the hold door device 8 are opened in conjunction with the car door device 17 under the control of the control panel 30 (S14), and the doorways 4 and 15 are opened.

  Then, passengers in the car 14 go down to the elevator hall 1 on the destination floor through the entrances 4 and 15 (S15). After the passenger gets off, the car door device 17 and the hold door device 8 are closed (S16), and the entrances 4 and 15 are closed. After the car door device 17 and the hold door device 8 are closed, the light emitter 26 of the car 14 is turned off (S17), and the car 14 moves toward the elevator hall 1 corresponding to the next car call.

  Thus, when a passenger operates the car call button 13 in the elevator hall 1, the light emitters 25 on both sides of the entrance / exit 4 in the elevator hall 1 are first continuously turned on to alert the holder device 8, and further, the car 14. Arrives at the elevator hall 1 and the hold door device 8 starts to open, the illuminator 25 changes from continuous lighting to a blinking state, and more attention is drawn. Therefore, it is possible to increase the safety by properly preventing the danger that the passenger's hand or the like is drawn into the gap between the hold door device 8 and the entrance / exit 4.

  Further, when a passenger gets into the car 14 from the elevator hall 1 and operates the destination floor button 21, the light emitters 26 on both sides of the entrance 15 of the car 14 are continuously lit to alert the car door device 17, and further, the car 14. Arrives at the destination floor and the car door device 17 is about to open, the illuminant 26 changes from continuous lighting to a blinking state, and more attention is drawn. Therefore, it is possible to increase the safety by carefully preventing the danger that the passenger's hand or the like is drawn into the gap between the car door device 17 and the doorway 15.

  And since it is a method to call attention by turning on the light emitters 25 and 26, unlike the case of the announcement, the surroundings of the elevator hall 1 can be kept quiet, and the quietness can be sufficiently maintained. Even a facility that requires a particularly high level of silence can be applied without problems.

  In addition, the change in the lighting state of each light emitter may be combined with a form of changing from continuous lighting to blinking lighting, and may be combined with a change to emit different colors such as blue when continuous lighting and red when flashing. It is possible and this can raise the alerting precision more. In addition, when a passenger using a wheelchair operates a car call button in an elevator hall, it is possible to detect it and turn on the light emitter in a different form from the case of a normal car call so as to differentiate it It is.

  In the above-described embodiment, each door device of the elevator hall and the car has a double-open structure in which a pair of door panels move to the left and right, but a single-open door device in which one door panel moves to the left and right, or It may be a multi-stage single door type door device in which a plurality of door panels are arranged stepwise in the front and rear, and the plurality of door panels move in the same direction at different speeds.
