According to embodiment 1 explained above, the 1 st curved part case 6 and the 2 nd curved part case 7 irradiate light in the direction of the curved part 3b of the balustrade 3. Therefore, the balustrade 3 of the passenger conveyor can be uniformly illuminated without using a large number of light sources.
In addition, according to embodiment 1, no lighting fixture is required at the curved portion 3b of the balustrade 3. Therefore, dimensional changes due to changes in the order floor height of the passenger conveyor, production errors and mounting errors of the components of the passenger conveyor, and the like can be absorbed in the curved portion 3b of the balustrade 3. As a result, the degree of freedom in designing the passenger conveyor can be improved. Further, the occurrence of a dark portion in the error absorbing space can be suppressed.
Further, only one light source 8a may be provided at the bottom surface of any of the 1 st, 2 nd and 3 rd linear part housings 5a, 5b and 5 c. In this case, if the installation interval between adjacent housings is reduced with respect to the housing, the balustrade 3 can be uniformly illuminated with fewer light sources 8 a. Therefore, the manufacturing cost of the 1 st straight line section case 5 can be suppressed.
The light source 8b may not be provided on the side surface of the 1 st curved part case 6. In this case, if the installation interval between the adjacent housings is reduced with respect to the 1 st curved portion housing 6, the balustrade 3 can be uniformly illuminated without the light source 8 b. Therefore, the manufacturing cost of the 1 st curved line portion case 6 can be suppressed.
Further, the light source 8d may not be provided on the bottom surface of the 2 nd curved part case 7. In this case, if the installation interval between the adjacent housings is reduced with respect to the 2 nd curved portion housing 7, the balustrade 3 can be uniformly illuminated without the light source 8 d. Therefore, the manufacturing cost of the 2 nd curved line portion case 7 can be suppressed.
Further, a plurality of light sources 8c may be provided on the right side surface of the 1 st curved part case 6. In this case, the right side of the 1 st curved part case 6 can be illuminated more brightly.
Further, a plurality of light sources 8e may be provided on the left side surface of the 2 nd curved part case 7. In this case, the left side of the 2 nd curved part case 7 can be illuminated more brightly.
Further, the 1 st curved part housing 6 is provided to the linear part 3a continuous with one side of the curved part 3b of the balustrade 3. The 2 nd curved part housing 7 is provided to the linear part 3a continuous with the other side of the curved part 3b of the balustrade 3. Therefore, the curved portion 3b of the balustrade 3 can be illuminated from both the left and right directions by the 1 st curved portion case 6 and the 2 nd curved portion case 7. As a result, the balustrade 3 can be uniformly illuminated.
The brightness of the light sources 8b and 8c may be changed according to the installation location of the 1 st curved portion case 6. For example, the luminance of the light source 8c may be higher than the luminance of the light source 8 b. In this case, the brightness unevenness of the illumination can be adjusted. As a result, the balustrade 3 can be uniformly illuminated.
The brightness of the light sources 8d and 8e may be changed according to the installation location of the 2 nd curved part case 7. For example, the luminance of the light source 8e may be higher than the luminance of the light source 8 d. In this case, the brightness unevenness of the illumination can be adjusted. As a result, the balustrade 3 can be uniformly illuminated.
