The character display board 25 is composed of, for example, a disk-like character display board that includes numbers such as elevator levels. For example, when used for opening / closing an elevator door, a pattern (character) other than letters and numbers is used. There is also. The lens 24 is arbitrarily provided for enlarging the characters displayed on the character display board 25. A diffusion plate 26 that diffuses light is optionally provided below the character display plate 25. These members 23 to 26 are placed on the button base portion 22. On the back side of the button base portion 22, for example, a pair of conductive movable pieces 27 are provided along two opposing sides of the box-shaped button base portion 22. The movable piece 27 moves when the operation button portion 23 is pressed, and has, for example, tip portions 27a that protrude toward the base unit 11 (lower side) at two corners. A detailed configuration example will be described later.

Note that numbers (characters) / pictures and the like are displayed in a wide variety of ways of displaying numbers on the elevator hierarchy SW (contact switch). For example, when the number display method is a floating character, the number of molds produced may increase. Therefore, in the present embodiment, characters / patterns recognized from the button surface, such as numbers, are marked on the character display board 25 which is a separate component from the operation button unit 23 in order to make the components as common as possible.

  FIG. 5 is an exploded perspective view showing a detailed configuration example of the base unit 11. The base unit 11 includes, in order from the button unit 21 side, for example, a first reflecting plate 12, a second fixed piece (the position does not change due to the vertical movement of the push button), a base plate 14, and a second plate. , A substrate 16 such as a flexible printed circuit board (hereinafter referred to as “flexible printed circuit board”), and a fixed plate 17. The first reflecting plate 12 has an opening 12a at the position of a light source such as an LED disposed on the flexible printed circuit board 16, and a prism 18 and a prism base that accommodates the prism 18 at a position corresponding to the opening 12a. 19 are arranged.

The contact can be opened and closed. Furthermore, by disposing the contact switch at the four corners away from the central portion of the button, the LED 51 can be disposed at the central portion of the base unit 11, and the degree of freedom of the arrangement of the LED 51 can be improved. Furthermore, since the LED 51 can be mounted on the center of the button, the button can be efficiently illuminated, and the number of LEDs 51 mounted can be reduced. Furthermore, the light guide plate can be made unnecessary as compared with the conventional structure in which the LEDs 51 are arranged in the periphery and the light guide plate is provided on the entire surface. In addition, the degree of freedom of arrangement of components such as the resistor 52 is increased.

  In addition, using a contact switch simplifies the structure of the switch compared to using a tact switch, making it easier to shorten the stroke when opening and closing the contact, and making the contact body thinner. Is possible. Further, by simplifying the structure of the contact portion including the button operation mechanism, the number of parts of the mechanism portion can be reduced.
