    • PROBLEM TO BE SOLVED: To obtain an elevator car operation board that can easily specify a button of a desired destination floor.SOLUTION: The elevator car operation board 8 includes a plurality button groups 13 that are vertically arranged. Each button group 13 includes a five or ten destination floor buttons 10 that individually specify the destination floor of successive five or ten floors. Each destination floor button 10 is arranged in the same arrangement patterns by the button groups. The button groups 13 vertically neighboring are arranged so that the button groups 13 are vertically displaced from each other.
    • 要解决的问题:获得能够容易地指定所需目的地楼层的按钮的电梯轿厢操作板。 解决方案:电梯轿厢操作板8包括垂直布置的多个按钮组13。 每个按钮组13包括五或十个目的地楼层按钮10,其分别指定连续五或十层的目的地楼层。 每个目的地楼层按钮10由按钮组以相同的布置图案布置。 垂直相邻的按钮组13被布置成使得按钮组13彼此垂直位移。 版权所有(C)2012,JPO&INPIT

    • PURPOSE:To obtain the illuminating plate of a display medium which is low in cost and has uniform brightness by juxtaposing two sheets of transparent plates in such a manner that the irregular reflection surfaces face each other and that the spacing on one end side is wide and the spacing on the other end side is narrow and disposing a light source in the aperture part of the wider side by parting a reflection plates from the light source. CONSTITUTION:Two sheets of the transparent plates 1 are juxtaposed in such a manner that the respective irregular reflection surfaces face each other and that the spacing on one end side is wide and the spacing on the other end side is narrow. The light source 4 is disposed in the aperture part 5 on the wide spacing side and the reflection plate 6 is disposed apart from the light source 4. The light of the light source 4 is diffused and reflected by the inclined irregular reflection surfaces (dotted parts) 2 directly or after being reflected by the reflection plate 6. The reflected light is radiated through the transparent plates 1 to the outside. The light entering at the critical angle or below in the part having no dots is totally reflected and is guided toward the narrower spacing side of the transparent plate 1 and is radiated from the side end faces of the aperture part 9 between the two transparent plates 1 and the side end faces of the two transparent plates 1 to the outside. The display surface of the display medium 3 having the uniform brightness is obtd. in this way.
