In FIG. 1, 1 is a landing plate whose upper surface forms a floor surface of a lower entrance / exit (entrance), 2 is a circular movement between a lower entrance and an upper entrance (not shown), and an escalator is used on the upper surface 3 is a moving handrail that circulates between the lower entrance and the upper entrance so that the upper end is synchronized with the forward path side of the step 2, and 4 stands on deck boards 5 provided on both sides of the step 2. A balustrade that is provided and supports the movable handrail 3, 6 is a comb plate provided on the step 2 side of the landing plate 1.

  Reference numeral 7 denotes a light projecting portion provided on the step 2 side surface of the balustrade 4 in the manual portion 4a or in the vicinity of the manual portion 4a. Light from a light source (not shown) provided in the balustrade 4 is projected by this light. The light portion 7 irradiates the kicking surface 2a of the step 2 and predetermined information such as the driving direction is displayed on the kicking surface 2a. Here, the predetermined information such as the driving direction is displayed on the kick-up surface 2a of the step 2 within a predetermined range that is a predetermined distance away from the lower entrance / exit, and in particular, a user near the lower entrance / exit and the lower entrance / exit. Is displayed. Note that the light emitted from the light projecting unit 7 is displayed on the kick-up surface 2a when the step 2 passing through the predetermined range with the irradiation direction fixed reaches the display position such as the driving direction. It is good also as a structure projected, and predetermined information, such as a driving direction, is always displayed on the kicking surface 2a of the step 2 which detects the installation position and moving speed, moving direction, etc. of the step 2 and passes within the said predetermined range. In this way, the irradiation direction may be controlled.

  In addition, as a display means for projecting predetermined information such as a driving direction on the outside side of the step 2, that is, by projecting light from the light projecting unit 7 and displaying the kicking surface 2 a of the step 2, for example, a laser pointer, a phantom lamp, A liquid crystal projector or the like is employed. By adopting such a display means, it becomes possible to display an arbitrary driving direction display, a pattern, an advertisement, etc. at any time on the kick-up surface 2a, and easily change not only the display contents and the pattern but also the light color. It becomes possible to make it.

  By having such a configuration, it is possible to display the driving direction and the like on the raised surface 2a of the escalator step 2 in an easy-to-see manner, and it is also easy to change the display contents, and the entire display device can be configured at low cost. . That is, unlike the conventional case, the kicking surface 2a of the step 2 is displayed by irradiating light from the outside of the step 2 to the kicking surface 2a of the step 2 within a predetermined range, thereby displaying predetermined information such as the driving direction. Even if there is some dirt on the screen, the display contents are not likely to be difficult to see, and the driving direction etc. can be displayed even on the dirt so that the user can recognize the display contents reliably. it can.

  In addition, as described above, the display contents can be easily changed by adopting various display means, and the display contents can be changed without the need to replace stickers or the like for each step 2 as in the past. It can be carried out in a short time and at a low cost. In addition, when newly installing the above-mentioned display means, etc. on the existing escalator, it is not necessary to add a light source or the like to each step 2, and only the light projecting unit 7, the light source, the control device, etc. are added to the railing 4 Therefore, it is possible to reduce the working time and cost.

  In the first embodiment, the light projecting portion 7 is arranged on the side surface of the rail 2 on the step 2 side. However, if the driving direction or the like can be displayed on the kicking surface 2a of the step 2 moving within a predetermined range. The light projecting unit 7 and the light source may be arranged at any position. Therefore, you may arrange | position the light projection part 7, a light source, etc. in the other part of an escalator, or may arrange | position in the other facilities away from the escalator. However, by disposing the light projecting unit 7 on the side surface of the step 2 side of the balustrade 4 as in the first embodiment, it is possible to irradiate light from a position close to the raised surface 2a of the step 2, and the light source Power consumption can be reduced, and light is not obstructed by anyone other than the escalator user, which is practical.

  Further, from the viewpoint of energy saving or the like, the escalator is activated when the user detects a user by starting the escalator by operating the step 2 or the moving handrail 3, and when the user is not detected for a predetermined time, the step 2 or the moving handrail 3 There are those that place the escalator in a standby state by moving it at a low speed or moving it at a low speed. In the escalator having such a configuration, a sensor (not shown) for detecting a user is provided at the entrance / exit, and the start and standby states of the escalator are controlled based on the detection result of the sensor. By controlling according to the detection result of the sensor, various effects such as energy saving can be expected. In addition, although a specific content is demonstrated below, especially the case where a driving direction is displayed on the kick-up surface 2a of the step 2 by the said display means is demonstrated.

  FIG. 2 is a time chart showing the operation of the display device for the man conveyor according to the first embodiment of the present invention. In the escalator shown in FIG. 2, the entrance / exit is provided with the sensor for starting the escalator or setting it to a standby state. When the escalator is in a standby state and the step 2 and the moving handrail 3 are stationary, the driving direction is displayed on the kicking surface 2a of the step 2 within a predetermined range by the display means. Here, when the user who sees the display of the driving direction tries to get on the escalator, the user is detected by the sensor and accelerated at a predetermined acceleration until the step 2 and the moving handrail 3 reach a predetermined speed. The display of the driving direction on the kicking surface 2a of the step 2 is interrupted by the display means. That is, no light is emitted from the light source of the display means.

  In addition, when a new user is not detected within a predetermined time after the user is detected by the sensor, the step 2 and the moving handrail 3 are decelerated at a predetermined deceleration in order to place the escalator in a standby state. Eventually quiesced. Specifically, the time is measured by the timer at the same time that the user is detected by the sensor, and the escalator is shifted to a standby state when a new user is not detected by the sensor within the time set in the timer. If a new user is detected by the sensor within the time set in the timer, the time set in the timer is reset and time measurement is resumed. Then, when a new user is not detected within the time set by the timer and the escalator is shifted to the standby state, the display of the driving direction on the kicking surface 2a of the step 2 is resumed by the display means. The display of the driving direction by the means is continued until the user is detected by the sensor.

  By having such a configuration, in the escalator having the above configuration, the display of the driving direction can be performed only when necessary, and the energy saving effect can be improved. That is, when the escalator is in a standby state, the driving direction is displayed on the kicking surface 2a of the step 2 within a predetermined range by the display means, so that a user at the entrance / exit can easily change the driving direction. Can be recognized. Note that the driving direction is displayed when the escalator is in the standby state, because the step 2 and the moving handrail 3 are not operating in the standby state in the escalator having the above-described configuration, and thus there is no display by the display means. This is because a person who intends to use the escalator cannot recognize the driving direction.

  Further, when the user is detected by the sensor, the display of the driving direction on the raised surface 2a of the step 2 is interrupted, so that the power consumption of the display means can be reduced. In addition, when a user is detected by the sensor, the display of the driving direction is interrupted when there is a user, and when another user sees the user moving on the step 2, the driving direction is interrupted. This is because the direction can be easily recognized and it is not necessary to display the driving direction on the kicking surface 2a of the step 2. Therefore, it is possible to display the driving direction effectively without causing service degradation and to improve the energy saving effect.

  In FIG. 2, the display of the driving direction by the display means is interrupted at the same time as the user is detected by the sensor. For example, the driving direction is displayed after a predetermined time has elapsed since the user was detected by the sensor. The display of the driving direction may be interrupted when the speed of the step 2 reaches a predetermined value. Further, in FIG. 2, when a new user is not detected within a predetermined time after the user is detected by the sensor, the display of the driving direction by the display means is resumed simultaneously with the deceleration of the step 2. However, for example, even if it is configured such that the display of the driving direction is restarted after the step 2 is completely stopped, it goes without saying that the same effect as described above is obtained.

  FIG. 3 is a time chart showing the operation of the display device for the man conveyor in the first embodiment of the present invention. When the user is not detected for a predetermined time by the sensor, the step 2 and the moving handrail 3 are moved at a low speed, and the escalator is moved. Is shown in a standby state. The control of the display means in the escalator having the above configuration is basically the same as that shown in FIG. 2, and in this case, the same effect as that shown in FIG. 2 can be obtained.

In FIG. 4, reference numeral 8 denotes a light projecting portion provided on the floor surface of the lower entrance, and light from a light source (not shown) of display means provided below the landing plate 1 is emitted from the light projecting portion 8. The raised surface 2a of the step 2 within the predetermined range is irradiated and predetermined information such as the driving direction is displayed on the raised surface 2a. Other configurations are the same as those in the first embodiment. By having such a configuration, the same effect as in the first embodiment can be obtained, and light is applied from below to the kicking surface 2a of the step 2 within a predetermined range to display predetermined information. The shadow of the step 2 stands out, and a greater visual effect can be expected.
