Yes. The control device 50 is connected to a normal light emission control unit 78, and the normal light emission control unit 78 included in the control unit is connected to a plurality of normal light emission units 66.

  The safety device 70 is connected to an operation detector 76 that detects the operating state of each safety device 70. The operation detection unit 76 included in the control unit detects an operation state of the safety device 70, such as whether the limit switch of the first detection device 72 is operated and then returned or not returned. A notification light emission control unit 80 is connected to the operation detection unit 76, and notification light emission units 68-1 to 68-8 are connected to the notification light emission control unit 80.

  The normal light emitting unit 66 and the notification light emitting unit 68 of the lighting device 64 provided on the skirt guard 44 have their respective functions.

  The LEDs of the normal light emission unit 66 are controlled by the normal light emission control unit 78 to control the display color, lighting speed, blinking speed, and extinction. The normal light emission control unit 78 is controlled by the control device 50. And the normal light emission part 66 is controlled so that the escalator 10 is lit white, for example, during the normal operation, and is turned off during the stop. Note that the normal light emission control unit 78 can change the turn-on / off / flashing speed and display color of the LED for each normal light emission unit 66.

  As shown in FIG. 2, the notification light emitting unit 68 is installed in the vicinity of the safety device 70, and is provided at a position closest to the first detection device 72 and the second detection device 74. The notification light emitting unit 68 is in a light emitting state different from that of the normal light emitting unit 66 when the first detection device 72 and the second detection device 74 are operated. Specifically, it will be described later. In the block diagram of FIG. 3, reference numeral 68 </ b> A indicates a group of notification light emitting units 68 attached in the vicinity of the first detection device 72, the notification light emitting unit 68-1 is on the left side of the lower floor, and the notification light emitting unit 68-2. Is attached to the vicinity of the first detection device 72 on the right side of the lower floor, the notification light emitting unit 68-3 on the left side of the upper floor, and the notification light emitting unit 68-4 on the right side of the upper floor. Reference numeral 68B denotes a group of notification light emitting units 68 attached in the vicinity of the second detection device 74, the notification light emitting unit 68-5 is the lower floor left side, the notification light emitting unit 68-6 is the lower floor right side, and the notification light emitting unit 68. -7 is attached to the left side of the upper floor, and the notification light emitting unit 68-8 is attached to the vicinity of the second detector 74 on the right side of the upper floor.

(3) Light emission states of the normal light emitting unit 66 and the notification light emitting unit 68 Next, the light emission states of the normal light emitting unit 66 and the notification light emitting unit 68 will be described in order. In addition, the display color of LED demonstrated below is an illustration to the last, and another display color may be sufficient.

  First, during normal operation of the escalator 10, the normal light emitting unit 66 and the notification light emitting unit 68 are lit in the same light emission state (for example, white and all lamps), and the control device 50 and the notification light emission control unit 80. Control. The notification light emission control unit 80 receives a normal signal indicating that the safety device 70 is not operating from the operation detection unit 76, and turns on the notification light emission unit 68 in an all white light state.

  Next, the case where the first detection device 72 on the lower left side of the safety device 70 is operated will be described.

  The control device 50 detects that the first detection device 72 has been operated, stops the motor 20, and stops the movement of the step 30 of the escalator 10. In addition, the control device 50 turns off all the normal light emitting units 66 via the normal light emission control unit 78. In addition, the operation detection unit 76 detects that the first detection device 72 on the left side of the lower floor has been operated, and outputs a turn-off signal to the notification light emission control unit 80. The notification light emission control unit 80 includes all notification light emission units. 68-1 to 68-8 are turned off.

  Next, the motion detection unit 76 outputs a detection signal indicating the motion part (lower floor left side) of the first detection device 72 to the notification light emission control unit 80.

  Next, the notification light emission control unit 80 causes the notification light emission unit 68-1 closest to the first detection device 72 on the left side of the lower floor to emit the notification light emission unit 68-1 by turning on and off in red. Accordingly, the maintenance staff can determine at a glance which position the first detection device 72 has operated.

  Next, the notification light emission control unit 80 continues the red flashing of the notification light emission unit 68-1 for a certain period of time (for example, 10 seconds) even after the operated first detection device 72 is restored, and then displays the green flashing. Change the color. Note that the notification light emission control unit 80 continues the flashing of the notification light emission unit 68-1 in red if the operated first detection device 72 has not returned.

  In addition, the control device 50 outputs information about the operated first detection device 72 (information such as an operation part and an operation time) from the speakers 54 and 58 by voice.

  In addition, even when the first detection device 72 operates and returns after that, the operation detection unit 76 operates again when there is an abnormality again and the same first detection device 72 operates and the operation return is continuously performed. Counts the number of times. Then, when the number of continuous operations reaches a threshold value (for example, 5 times), the operation detection unit 76 increases the blinking speed of red flashing of the notification light emitting unit 68-1. However, when another safety device 70 operates before the threshold is reached, the operation detection unit 76 clears the count of the number of continuous operations. Then, the notification light emitting unit 68 closest to the other safety device 70 that has been operated is caused to emit light to the notification light emission control unit 80. The reason for clearing this count is that when the other safety device 70 is operated, the escalator 10 is stopped, and the safety device 40 during the continuous operation does not operate any more.

  In the above embodiment, the first detection device 72 on the left side of the lower floor has been described. However, the present invention is not limited to this, and the first detection device 72 on the right side of the lower floor, the left side of the upper floor, the right side of the upper floor, or the second detection device 74 operates. The detection unit 76 and the notification light emission control unit 80 similarly control the notification light emission units 68-2 to 68-8.

(4) Effects In the present embodiment, based on the light emission state of the notification light emitting unit 68 in the lighting device 64 provided in the skirt guard 44, the maintenance staff can determine at a glance which safety device 70 has been operated. The operation status can also be displayed. Therefore, when an abnormality occurs in the escalator 10 and the maintenance staff arrives at the site, the position and operating state of the safety device 70 that has been operated at a glance can be confirmed, and since audio broadcasting is also performed, Information is easy to understand. Therefore, the time required for the investigation and recovery of the escalator 10 can be further shortened.

  Further, by detecting the case where a specific safety device 70 is operating continuously and displaying the information, the maintenance staff can judge the safety device 70 that needs to be investigated and adjusted intensively. Occurrence can be prevented.

(5) Modification Example In the above embodiment, the first detection device 72 and the second detection device 74 have been described. However, the present invention is not limited to this, and may be applied to a light emitting unit provided in the vicinity of another safety device 70.

  Further, in the above embodiment, the description has been made by adapting to the step 30 of the escalator 10, but instead of this, it may be adapted to a step (step) of a moving sidewalk.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
