Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention is applied to automobiles.
The invention applies to buses. The present invention relates to an improvement in a device for electronically displaying a destination.

[0002]

2. Description of the Related Art Conventionally, a destination display board of a bus has a structure in which a destination character is written on a cloth material and illuminated from behind. The cloth fabric is wound up according to the destination and a desired portion is displayed. A device for displaying a destination on the side of a bus is also known, but the display of the destination is fixed.

[0003] In addition, a device for providing a lightning display board inside a railway vehicle to guide a destination or a next stop station, or a device for displaying lightning news for passengers has been used.

[0004]

In recent years, it has become possible to obtain an inexpensive light-emitting display panel that can be seen well in the daytime. Further, the control device for driving the light-emitting display panel has also become inexpensive. The operation of rewriting the information displayed on the electronic signboard has also been simplified.

[0005] On the other hand, in the case of route buses, display boards for guiding and displaying the destination of the bus to passengers waiting for the bus on the sidewalk are provided in principle in front of and behind the vehicle. Some devices are located on the side of the vehicle, but most are located near the entry / exit doors and are small in character and difficult to see by people waiting in the sidewalk. In particular, it is inconvenient for a person with weak vision to make the display difficult to understand.

The present invention has been made in such a background, and an object of the present invention is to provide a display that is easy to see and understand for a person standing on a sidewalk or a side of a road and waiting for a bus.

[0007]

The present invention is characterized in that a destination display of a route bus is displayed on a side surface thereof so as to flow backward.

That is, according to the present invention, an elongated electro-optical display panel is provided on the side of the vehicle, display information is stored in the memory means, and the stored display information of characters or figures flows from the front to the rear of the vehicle. To be displayed.

The vehicle slows down near the stop.
When the output of the vehicle speed sensor is lower than the predetermined speed V, a character or a graphic (a destination in the case of a route bus) is displayed on the electric display panel so as to flow at substantially the same speed as the vehicle.
Even if the vehicle is moving, the characters or figures can be shown in a stopped state to the passengers waiting at the stop.

[0010] When a passenger is waiting at a stop and a vehicle approaches, the destination display ahead can be seen, but when the vehicle is stopped at the stop, the vehicle comes later and tries to get on. Sometimes, it is displayed in small characters, but it is difficult to instantaneously confirm the destination. Since the present invention is displayed large on the side of the vehicle in addition to the display of the front and the rear, the destination can be easily confirmed even at a position slightly away from the stop.

The display information stored in the memory means can be rewritten by operating the operation means. For example, the display can be rewritten by an operation of inserting a destination card into a card reader.

[0012] By performing such display, the destination display is easy to see even for passengers whose dynamic visual acuity is degraded, and the trouble of listening to the driver without knowing the destination can be eliminated.
