The information display 5 is controlled by the controller 50 for advertisements, types of advertisements, order, and the like.
[0028]
(Work)
With reference to FIG. 1 thru | or FIG. 3, the effect | action of the information display apparatus A1 for motor vehicles based on this reference form is demonstrated.
As shown in FIG. 1, the information display device 5 constituting the automobile information display device A <b> 1 is attached to the rear side of the rear window 90 of the automobile 9 such as a taxi, for example, with the display portion directed rearward (outside). .
The information display 5 displays a moving screen by scrolling or the like, and can provide various information such as various advertisements and emergency information to the rear car and surrounding pedestrians.
[0029]
When the vehicle 9 is in a travel stop state due to a signal or the like, both the manual switch 2 and the automatic control switch 3 are in a closed state (hereinafter referred to as ON), and the information display 5 is energized and displayed on the display unit. Advertisements and advertisements are scrolled.
[0030]
When the vehicle 9 starts and enters a running state, the speed detector 4 detects that the vehicle is in a running state, and the automatic control switch 3 is actuated by a signal from the speed detector 4 to open (hereinafter referred to as OFF). ) Thereby, the power supply to the information display 5 is cut off and the display is not scrolled in the display screen. At this time, nothing is displayed on the display screen of the information display 5.
[0031]
When the automobile 9 is in a running state, the driver manually turns off the manual switch 2 so that the battery 1 is not energized to the automatic control switch 3.
As a result, even if the automatic control switch 3 does not operate normally due to a mechanical failure or an electrical failure and the information display 5 can be energized in the running state, the manual switch 2 is turned off. As a result, the supply of electricity from the battery 1 is reliably cut off, and as a result, the display is not scrolled.
[0032]
When the automobile 9 is changed from the traveling state to the traveling stopped state, the automatic control switch 3 is activated by the signal from the speed detector 4 and the information display 5 can be energized, but the manual switch 2 is OFF. Therefore, the information display 5 is not energized and the display is not scrolled.
In this state, when the driver further turns on the manual switch 2, the automatic control switch 3 is energized from the battery 1, the information display 5 is also energized, and the display on the information display 5 is scrolled.
[0033]
Thus, in the information display device A1 for automobiles, turning off the manual switch 2 while the automobile 9 is traveling becomes a safety device for preventing the display on the information display 5 from scrolling.

Further, the description of the structure of the automobile information display device A2 is omitted from the description overlapping with the automobile information display device A1.
[0035]
The vehicle information display device A2 according to the present embodiment includes a manual control switch 2a instead of the manual switch 2. Reference numeral 7 denotes a switch controller which receives a signal from the speed detector 4 and turns on the manual control switch 2a when the vehicle is stopped.
The manual control switch 2a has a structure in which the operation to turn off is manually performed and the operation to turn on is automatically controlled by the switch controller 7. However, the manual control switch 2a may be manually turned on.
Further, the switch controller 7 is configured to detect the vehicle speed signal sent from the speed detector 4 by the control unit, and to turn on the manual control switch 2a when the automobile is in a travel stop state. Means can be employed.
[0036]
Reference numeral 6 denotes an information display connected in parallel with the information display 5 and is an LC (liquid crystal) display. The information display 6 is controlled by the controller 60 for advertisements, types of advertisements, order, and the like. Similarly to the information display 5, the information display 6 does not display the moving screen display when the automobile 9 is in the running state, and performs it when the automobile 9 is in the running stopped state. When the automobile 9 is in a running state, a still screen is displayed.
[0037]
Reference numeral 8 denotes an emergency manual switch device, and when it is turned ON, the same signal as the vehicle speed signal sent when the speed detector 4 is in the travel stop state is sent to the switch controller 7 of the manual control switch 2a and the control unit of the automatic control switch 3. And an emergency signal is sent to the controllers 50 and 60 of the information displays 5 and 6.
As a result, even when the automobile is running, by turning on the emergency manual switch device 8, the manual control switch 2 a and the automatic control switch 3 are turned on and the information display 5 is selected by the controllers 50 and 60. Emergency information can be scrolled.

[0039]
Since the vehicle information display device A2 employs the manual control switch 2a instead of the manual switch 2, when the vehicle 9 is stopped, the manual control switch 2a is turned on and the automatic control switch 3 is energized. The operation is performed automatically by the switch controller 7 and need not be performed manually.
Thereby, unlike the manual switch 2 of the automobile information display device A1, there is no trouble of manually turning on when the vehicle is stopped, and the screen display can be surely scrolled when the vehicle 9 is in the stopped state. .
[0040]
Further, the automobile information display device A2 is provided with an emergency manual switch device 8. When the information must be displayed urgently for some reason and secretly outside the vehicle, the emergency manual switch device 8 is turned on. Thus, both the manual control switch 2a and the automatic control switch 3 can be turned on even when the manual control switch 2a and the automatic control switch 3 are turned off in the running state.
[0041]
As a result, text information which is emergency information selected by the controller 50 in response to an emergency signal from the emergency manual switch device 8 is scroll-displayed on the information display 5 with LED display, and the information display 6 with LC display is displayed on the information display 6 with LC display. Similarly, a moving image that is emergency information selected by the controller 60 is displayed.
[0042]
In the automobile information display device A2, an information display 5 that is an LED display and an information display 6 that is an LC display are used in combination. Since the LC display generally has a larger amount of information that can be displayed on the screen than the LED display, it is possible to display information that cannot be displayed on the LED display, so that the types and variations of information that can be displayed can be increased.
[0043]
