Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a taxi-rooftop display device.

[Prior art]

Traditionally, ``empty cars'' are displayed on the dash board inside the taxi.
It is well known that a display device is installed to display characters such as , etc., and is configured to be visible from the outside through the windshield. The "empty vehicle" display on the display is all one-sided and can only be seen from the front;
In rare cases, there are taxi cars that have an additional indicator installed at the rear so that the "vacant" display can be seen from behind through the rear window.

Conventional taxi vacancy indicators can be roughly divided into two types. One is a system in which an vacancy display board is fixed to the operating arm of the taxi meter, and when the display board is tilted down, the taxi meter starts calculating coefficients. There are two types: one is a manual type, and the other is electrically connected to a taxi meter and configured so that a designated display appears when the line voltage is switched by pressing a button on the meter. The latter type of display displays ``empty car'' and ``surcharge'' by switching the blinking position of a lamp, and the other uses electromechanical rotation of a tape with multiple display surfaces to display a designated display. There is a monitor display with a flashing lamp on the back of the display.

The conventional display mentioned above does not have a double-sided empty vehicle display, and the display can only be seen from the front of the taxi.In order to make it visible from the rear, an additional display must be installed. There must be. A taxi car with one empty car indicator installed in the front and one empty car indicator in the rear can inform the passengers and following cars of the status of ``empty car'' and ``actual car'', but the empty car indicator in the front When posting a board displaying ``forwarding'' in front of a board, there were many cases where the same message was not posted on both the front and back, resulting in cases where customers complained because the front and back messages were different.

In addition, taxi cars with a ``Forwarding'' board posted in front of the empty vehicle display had complaints from customers because the ``Forwarding'' sign was difficult to see at night because the word ``Forwarding'' was not displayed with light.

Furthermore, because the conventional empty taxi display is hidden behind the vehicle in front during traffic jams and cannot be seen, passengers who see the taxi just before the taxi will raise their hands and the taxi will suddenly stop near the sidewalk. There were many. In addition, among conventional empty vehicle indicators, the display of optical display types fades due to sunlight, and in particular, if the display surface is facing direct sunlight, the empty vehicle display becomes invisible, and passengers may not be able to see the empty vehicle display until a taxi arrives just before. There were many cases where people raised their hands, and all of them were unfavorable in terms of accident prevention.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and provide a display device for a taxi that can be easily checked from the front and rear directions of the vehicle.

[Means to solve problems]

The present invention solves the above problem by horizontally juxtaposing a signboard display section that displays predetermined content in a fixed manner and a switching display section that can be displayed on both the front and back sides and that can switch the displayed content. This problem has been solved by a display device for a taxi, which is characterized in that the display contents can be switched and controlled by a control device inside the vehicle, and the signboard display section and the switching display section are formed so that they can be illuminated from inside.

[Function] The switching display unit is connected to a taxi meter or the like via a sign controller, and in conjunction with the push button operation of the meter, the display surface of the display can be changed to indicate, for example, "vacant" or "rental". A selected one of the three display surfaces of display characters, plain color display, and "pick-up vehicle" is switched so that it appears in the display windows on both sides of the display device. In conjunction with this and the on/off of another individual display selection switch, for example, one display screen selected from among the two displays "Forwarding" and "Chartered" or "Reserved car" will be displayed in the above-mentioned double-sided display window. It can also be configured to appear in A security light is installed inside the interior cover of the sign display section, electrically connected to the security light switch via the sign controller, and the internal lighting components of the switching display section and the sign display section are connected to the taxi car via the sign controller. It is electrically connected to the small lamp switch light, and the internal lighting member lights up or the red security light flashes when both switches are turned on and off. By removing the cover of the display device, the lighting member can be detachably slid and taken out of the machine to easily replace lighting lamps and the like.
