Description

  The present invention relates to an escalator device, a moving sidewalk device, and an elevator device having an information presentation function using electronic paper that retains display even when the power is turned off.

  In the information presentation by the conventional escalator device, the moving sidewalk device, and the elevator device, as shown in FIG. 5 is performed by attaching a sticker 14 or the like on which information is displayed.

However, according to the above technique, the information is updated by means of printing a new seal, peeling off the existing seal, and applying a new seal. However, the execution of these means requires troublesome work and time for temporarily stopping the apparatus, and there has been a problem that information cannot be updated immediately.
Accordingly, an object of the present invention is to provide an apparatus that can easily and immediately present information without stopping the apparatus.

  In order to solve the above-described problems, the first invention has electronic paper that can maintain its display even when the handrail is turned off, and information can be presented by printing on the electronic paper by a printing device. An escalator device and a moving sidewalk device characterized by the above.

In addition, the second invention is characterized in that electronic paper that maintains a display even when the power is turned off is added to the door portion, and information can be presented by printing on the electronic paper by a printing device. It is an elevator device.
The third invention is an escalator device, a moving walkway device, and an elevator device characterized by using electronic paper having a common electrode on the non-observation surface side.

  Further, according to a fourth aspect of the present invention, there is provided an escalator device in which the electronic paper is printed by a printing device having a plurality of write heads synchronized with the moving speed of the handrail and the door with respect to the same dot on the electronic paper, It is a moving walkway device and an elevator device.

  According to a fifth aspect of the present invention, there is provided an escalator device, a moving sidewalk device, and an elevator device characterized in that the electronic paper is initialized before printing by a dedicated erasing head.

  According to the first invention, an electronic paper that holds a display even when the power is turned off is added to the handrail portion, and information is erased and printed on the electronic paper by the printing device in time as the handrail moves, and the information is updated. Simple and quick.

  According to the second invention, electronic paper is added to the door portion so that the display is maintained even when the power is turned off, and information is erased and printed on the electronic paper by the printing device in accordance with the opening and closing movement of the door. Is done conveniently and quickly.

According to the third invention, a structure having a common electrode on the non-observation surface side is possible, and an expensive and transparent electrode is not required for the common electrode.
According to the fourth invention, the time required for printing on the electronic paper can be obtained as a cumulative total with respect to the handrail of the escalator device, the moving sidewalk device and the elevator device, and the moving speed of the door.

  According to the fifth aspect, it is possible to initialize the print information on the electronic paper without the need for alignment by a dedicated erasing head. Further, by providing an erasing dedicated head, it is possible to apply an electromagnetic field under conditions different from those during printing, and erasing can be performed in a short time.

One embodiment of the first invention is shown in FIG.
An electronic paper 1 is added to the handrail 2 of the escalator device. The printing device 4 is added to the return path portion of the escalator device handrail 2.

An embodiment of the second invention is shown in FIG.
The electronic paper 1 is added to the elevator device door 5. The printing device 4 is installed in the door pocket 6.

An embodiment of the third invention is shown in FIG.
The common electrode 16 is disposed on the side (non-observation surface) that contacts the handrail 2 and the like of the escalator device, and the other structural portion 7 of the electronic paper is disposed on the observation surface side.

An embodiment of the fourth invention is shown in FIG.
In the printing device 4, a plurality of print heads 9, 9 a, 9 b corresponding to the same print dots 8 on the electronic paper 1 are arranged in the moving direction of the electronic paper 1.

An embodiment of the fifth invention is shown in FIG.
An erasing head 10 is disposed immediately before the printing head 9 of the printing apparatus 4 installed in the passage portion of the electronic paper 1.

"Effect of the embodiment"
According to the embodiment of the first invention, the information printed on the electronic paper 1 by the printing device 4 appears on the outward path touching the human eye as the handrail 2 of the escalator device 3 moves. As the escalator device 3 moves, the handrail 2 turns back and is erased and printed again by the printing device 4 in the return (return) portion, and the information is updated.

  According to the embodiment of the second invention, when the door 5 of the elevator apparatus is opened and closed, the electronic par 1 installed on the door 5 is also drawn into or out of the door pocket portion 6. . At that time, the information is erased and printed by the printing device 4 installed in the door pocket portion 6 and the information is updated.

  According to the embodiment of the third invention, the common electrode 16 of the electronic paper is installed on the handrail 2 of the escalator device on the non-observation surface side. This eliminates the need to use a transparent common electrode such as an indium oxide thin film that has been used on the observation surface side. Thereby, an inexpensive metal thin film (such as stainless steel) can be used as an electrode material.

  According to the fourth embodiment, there are a plurality of print heads 9, 9 a, 9 b corresponding to the same dot 8 on the electronic paper 1 in the moving direction of the electronic paper 1, and synchronized with the moving speed of the electronic paper 1. The plurality of print heads 9, 9 a and 9 b sequentially write on the same dot 8 on the electronic paper 1. When the time required for writing information on the electronic paper 1 is longer than the passing time on the print head depending on the moving speed of the electronic paper 1, writing is performed by arranging the print heads 9 for the time required for writing.

According to the embodiment of the fifth invention, the erasing head 10 is installed immediately before the printing device 4. When the erasing head 10 collectively applies an electromagnetic field to the electronic paper 1, it is possible to collectively erase print information on the electronic paper 1. Further, by providing the erasing head 10 independently of the print head 9, erasing can be performed under conditions unique to the erasing that are different from the writing conditions in the printing head 9. Further, in order to perform erasing and writing simultaneously with the print head 9 of the printing apparatus 4, it is necessary to accurately align the print dots on the electronic paper 1 and the print head 9, but in this embodiment, the alignment is performed. Is no longer necessary.
