The number mark display portion 51a merely indicates that a floor display portion described later is provided, and is composed of four convex portions in which the display is fixed by sticking a plastic piece or a metal piece. It The tip of the convex portion, which is the portion that the visually impaired person touches with the fingertip, is processed into a spherical surface so as to have a curved surface in order to improve the touch.

The center girder and the rightmost girder are floor display parts 51b and 51c for displaying the current position (floor) of the car. The center digit displays the tens digit, and the rightmost digit displays the ones digit. Floor display section 51
Since the indications of b and 51c are appropriately changed according to the current position of the car, six protrusion bars, which will be described later, which form Braille generally specified for visually impaired users are present positions of the car for each digit. Depending on the appearance, the Braille display on the floor can be changed.

Then, 52ba to 52bf and 52ca
The symbols 52 to 52cf are protruding rods that form Braille by appearing and disappearing in the outward direction (toward the car interior) of the display unit 5f to represent the floor. The number mark display portion 51b is provided with protrusion bars 52ba to 52bf, and the number mark display portion 51c is provided with protrusion bars 52ca to 52cf. Then, the protruding bars 52ba to 52bf and 52ca to 52cf

Further, the cross section of the display portion 5f is constructed as shown in FIG. Here, the protruding bars 52ba to 52ba
As a representative of bf and 52ca to 52cf, the protruding bar 52c
Description will be made by taking d as an example. A spring locking portion 53cd, on which one end of a return spring 54cd described later is locked, is attached to the protrusion bar 52cd.
Is provided. The return spring 54cd is provided between the front plate 50c and the spring locking portion 53cd, and has one end locked to the front plate 50c and the other end locked to the spring locking portion 53cd. In the return spring 54cd, the tip of the protrusion bar 52cd is normally buried in the display portion 5f without protruding from the front plate 50c due to the restoring force (extension force) of the spring.

A permanent magnet 55cd is provided at the end of the protruding bar 52cd, which is always inside the display portion 5f and on the side where the visually impaired cannot touch it with a fingertip. The S pole of the permanent magnet 55cd is arranged on the side of the protruding rod 52cd, and the N pole faces the electromagnet iron core 56cd. The protruding rod 52cd and the permanent magnet 55cd are guided to move in and out by a cylindrical guide (not shown) whose one end is fixed to the front plate 50c.

On the other hand, the electromagnet iron core 56cd has a display portion 5f.
It is supported on the inner surface facing the front plate 50c of the housing. A coil winding 57cd is wound around the electromagnet iron core 56cd, and the electromagnet driving unit 6 as a Braille forming command output unit is provided.
The exciting current output from the device is designed to flow. The electromagnet iron core 56cd facing the permanent magnet 55cd generates an N-pole magnetic pole on the side facing the permanent magnet 55cd when an exciting current flows through the coil winding 57cd. As a result, the permanent magnet 55cd is replaced by the electromagnet iron core 56cd so that the protruding bar 52cd projects from the front plate 50c.
