Description

  The present invention relates to a passenger conveyor guide device that indicates a moving direction of a step.

  In order to meet the diverse needs of various users, including the elderly and persons with disabilities, and to make it easier for all users to use, public transport passenger facility mobility facilitation maintenance guidelines were formulated. Along with this, in the passenger conveyor, a direction display device that informs the user of the moving direction is installed at the boarding / alighting part of the railing, or a guidance device that provides voice guidance of the destination at the entrance is installed (for example, the following) Patent Document 1).

  However, when the direction display device displays the moving direction of the steps of the passenger conveyor, it is difficult for a visually impaired person to recognize the moving direction of the steps of the passenger conveyor to be used.

  Also, passenger conveyors installed at station platforms, etc. have high noise such as train running noise and train guidance broadcasts, so it may be difficult for users to hear voice guidance from passenger conveyor guidance devices. . In particular, in voice guidance, if words that are important for knowing the content of guidance cannot be heard, necessary information is not transmitted to the user even if other words can be heard.

  Therefore, if the visually impaired cannot hear the voice guidance from the guidance device, the visually impaired person may recognize the moving direction of the steps of the passenger conveyor by entering the entrance / exit and touching the handrail belt. This confirmation method may cause a major accident. For example, if a visually handicapped person approaches the exit of a passenger conveyor that moves downward and touches the handrail belt, the user who has been transported from the upper floor to the lower floor will stay at the exit, and in some cases There is a possibility of developing into a major accident where people fall over and fall in shogi.
