  The present invention relates to a traveling direction display device that displays a traveling direction of a man conveyor.

  A conventional traveling direction display device is provided with a handrail belt having a substantially C-shaped cross section formed by a surface flat portion and both edge portions, moving in an inverted manner from the forward path to the return path, and a color of the handrail belt on the surface of the handrail belt. And at least one direction display mark that is provided across the flat surface and both edges of the handrail belt and that indicates the direction of movement of the handrail belt in the semicircular range of the reversing portion. In some cases, a print sheet is provided which has a plurality of the entire length, and within which the caution characters and advertisements are displayed.

  According to this traveling direction display device, due to the presence of the direction display marks on both edges, the moving speed and the moving direction can be visually recognized even from the side of the passenger conveyor. It is easy to prevent a fall accident due to a failure in getting on the passenger conveyor, to prevent reverse boarding, and to recognize the moving speed and moving direction from the side of the passenger conveyor (see, for example, Patent Document 1).

Is provided.

  It has been described that when the display is fixed to a position where the electronic paper 60 is first moved, the handrail belt 5 moves as the handrail belt 5 moves as indicated by the rising arrow on the left side of FIG. By returning the position of the electronic paper 60 that displays the rising arrow by the distance when moved at the speed by the distance that the handrail belt 5 moves in the direction opposite to the moving direction of the handrail belt 5, the rising arrow on the right side of FIG. It seems to be stationary from the person standing on the landing plate. In the present application, the position of the electronic paper 60 displaying the mark indicating the traveling direction and the mark indicating that the passenger conveyor 4 is running or stopped is moved in the direction opposite to the movement of the handrail belt 5. This is called scrolling.

FIG. 4 is a flowchart showing the operation of the traveling direction display device of the best mode for carrying out the present invention.
Next, the operation of the traveling direction display device of the best mode for carrying out the present invention will be described. The description starts from the state in which the passenger conveyor 4 is stopped, and the passenger uses the escalator 1 from the lower floor to the upper floor.
In step S101, it is determined whether or not the human sensor 2 has detected a person. When a person is detected, the process proceeds to step S102, and when no person is detected, step S101 is repeated.
In step S102, a human detection signal is generated and the process proceeds to step S103.
In step S103, a travel signal is generated and the process proceeds to step S104.
In step S104, an upward direction signal is generated as a direction detection signal, and the process proceeds to step S105.
When the travel signal and the upward direction signal are input in step S105, the control device 50 travels the motor 24 and proceeds to step S106.
In step S106, the encoder 28 generates a position detection signal and proceeds to step S107.
In step S107, the speed detection unit 51 generates a handrail belt speed detection signal, and the process proceeds to step S108.

In step S108, when the reception unit 71 receives the upward direction signal and the handrail belt speed detection signal transmitted from the transmission unit 59, the first scroll unit 73 generates a first movement signal, and the first display position unit 75 The position for displaying the up arrow or the down arrow is specified, the direction switching unit 77 selects the up arrow from the up direction signal, and the traveling direction display unit 79 displays the up arrow at the specified position.
In step S109, the second scroll unit 81 generates a second movement signal, the second display position unit 83 specifies the position where “traveling” is displayed, and the travel / stop display unit 85 is displayed at the specified position. “Running” is displayed.

  The traveling direction display device according to the present invention is stationary as viewed from a person who is about to get a mark indicating the traveling direction based on the moving speed of the handrail belt 5 when the passenger conveyor 4 is traveling and the handrail belt 5 is moving. Since the position of the electronic paper 60 that displays the mark is scrolled as shown, the mark indicating the traveling direction appears to be stationary, and the visibility is improved.

  In the traveling direction display device according to the present invention, the magnet 66 is fixed in the vicinity of the position where the mark indicating the traveling direction is displayed, and the electronic paper 60 passes through the magnetic flux of the magnet 66 to pass through the electronic paper 60. An electromagnetic coil 68 for confirming the reference position is provided, and the position of the electronic paper 60 that displays the mark indicating the traveling direction is specified based on the reference position of the electronic paper 60. Therefore, the reference point for the circulation of the handrail belt 5 Even if there is a slight shift, the mark indicating the direction of travel is viewed as if it is in a certain place as seen from the person who is trying to get in.

In the traveling direction display device according to the present invention, the direction detection unit 53 detects the traveling direction of the passenger conveyor 4 to generate a direction detection signal, and the direction switching unit 77 indicates the traveling direction based on the direction detection signal. Since the chapters are switched, a mark indicating the traveling direction can be easily displayed corresponding to the traveling direction of the passenger conveyor 4.
In addition, although the example which installed the advancing direction display apparatus in the escalator 1 was demonstrated above, the advancing direction display apparatus which concerns on this invention is applicable also to man conveyors, such as a walk sidewalk.
