That is, in this embodiment, 4 characters or 32
Eight texts 51 to 58 consisting of characters are prepared, and four types of messages 61 to 64 can be set by combining these texts 51 to 58 arbitrarily (selection and order).

<Description of Message Registration Operation> First, an outline of the message creation (including display settings) procedure of the display device according to this embodiment will be explained. First, when the operator starts creating a message, he selects the operating mode of the device using the selection key 21 in FIG.
■Text editing mode for inputting text (character strings), ■Display attribute editing mode for setting text display time, etc.
One of the message editing modes for setting a message based on multiple texts is executed.

This mode selection is performed using the CP as shown in FIG.
U41 (Figure 4) starts creating a message (step 1)

If yes, change character position number (step 115)
), and if there is no change, it is determined in step 116 whether or not the font has been selected, and if there has been a change, the font is selected (step 117) and the changed contents are displayed (step 118). be.

Specific key operations and display screens for this operation will be explained with reference to FIG. 2 showing the key arrangement, FIG. 4 showing the circuit configuration, and FIG. 8 showing the display screen. This FIG. 8 is a diagram for explaining the text input procedure, and the numbers 81 to 8
Reference numerals 7 and 88 represent screens displayed on the message display section 3 by key operations on the operation panel 4 shown in FIG. Now, first, when the operator wants to register a new text, when he presses the selection key 21 on the operation panel 4 (Fig. 4), the data bus 4
7, the CPU 41 displays a screen 81 on the display section 3. This screen shows the position of the character TXT (text) “1” (PO
SI: Position) is the character font (FO
NT) is currently "0" (the leading font zero shown in FIG. 7), and the FONT is surrounded by a thick frame, indicating that text is currently being edited. By pressing the up key 24 in FIG. 2 several times in this state, the character fonts are successively incremented one by one and displayed.

In this figure, in order to input the first character font of text 1, press the up key 24 or the down key 25.
By pressing , the CPU 41 sequentially reads character fonts from the font memory 42 and displays them at the right end of the screen. The displayed character font changes from the upper left to the lower right in FIG. 7 in the order of 0 → 1 → 2 → 3 to protection → speed → speed. This change is made using the shift key 23 and the up/down key 24 or 2.
You can jump and select by pressing 5 and 5 at the same time. This shift mode is displayed as [JMP UP] at the bottom of the key in FIG. In this example, keep pressing the up key 24 until "cross" is displayed as shown in screen 82, and change the font of the first character of text 1 to "
Set to ``Interchange''.

Next, when the skip key 22 is pressed, the CPU 41
The character position (POSI) is shifted to the second character mode as shown in the screen 83, and the next character "tsu" read from the font memory 42 is displayed. This skip key 22 can be pressed at the same time as the shift key 23 to move backward in character position numbers. After setting this character position,
By selecting the character font using the up and down keys 24 and 25, "An" and "All" are set in the third and fourth character positions as shown in screens 84 and 87, and Text 1 is registered. The content of text 1 in this case is "traffic safety."

Next, the mode change to text 2 and beyond is performed by pressing the selection key 21 as shown in screen 88.
Similarly, arbitrary character phantoms for the eight texts 51 to 58 shown in FIG. 5 are registered as texts in the static/moving text memory 44. Note that the above-mentioned text registration can also be performed using each key of the remote control switch 45. Further, the selection key 21 can also be pressed simultaneously with the shift key 23 to move the text number backward. In addition, the shift key 23 and the memory key 26
It is also possible to cancel the operation (CAN) by pressing and at the same time. <Description of Message Registration and Display Operations> The procedure for registering (editing) a message with the aforementioned eight texts 51 to 58 registered will be described using FIG. 13.

First, start editing the message (step 13)
0) and there is no mode switching (determined as NO in step 131), and the "message number" is set by the skip key 22.
Or, if it is determined whether or not an item in "display number order" is selected (step 135), and if it is not, change the item content (text number to be displayed) using the up or down key 24 or 25 (step 137), and then change the changed content. (step 138). In addition, step 1
If the "message" or "display number" item is to be switched using the skip key 22 in step 35, the change is made in step 136 and then the changed contents are displayed (step 134).

Specific key operations and display screens for this operation will be explained with reference to FIG. 2 showing the key arrangement and FIG. 9 showing the display screen. First, the screen 90 on which eight texts have been registered will be explained in the same way as in the previous explanation. When the selection key 21 is pressed when this text (TXT) 8 is finished, the CPU 41 (FIG. 4) displays a message (
The display section 3 displays a screen for setting the array (STRING) of MSG)1. N1 to N4 on the right side of this screen each indicate the numerical order of the texts to be displayed, and the right side of "=" indicates the number of the text to be displayed. For example, in the example of screen 91, the first (N1) is text 3, the second (N2) is text 1, the third (N3) is text 4, and the fourth (N4)
This indicates that text 5 is to be displayed. Note that "N" in N1 etc. indicates No (number).

Now, to set the text arrangement order for this message 1, move the cursor to N1 using the skip key 22 as shown in screen 91, and then use the up key 24 or the down key 25 to move the cursor to N1 on the right side. The text number is set by cycling in the order of 1 -> 2 -> 3 - -> 8 -> 1 (the rotation direction can also be changed in the opposite direction using the shift key 23). That is, an arbitrary text number is displayed using the key 24 or 25 in the display number order (N1 to N4) of the cursor position positioned using the skip key 22, and the text number is input by moving to another number order using the skip key 22. .

After inputting message 1, the next message can be registered by pressing the selection key 21.
This is done while the PU 41 changes the message (MSG) number, and thereafter registers an arbitrary text number to each message in the same manner. This allows arbitrary text to be set in any order for the four messages as shown in screens 91-94. In this example, each message is
The setting is shown so that three static texts (text numbers 1 to 4) are displayed and then moving texts (text numbers 5 to 8) are displayed.

When the storage key 26 is pressed when all message registration is completed, the CPU 41 stores the setting contents in the static/moving text memory 44, displays a message indicating the completion of registration as shown in screen 95, and then displays screen 96. It operates by displaying the text of registered messages in sequence to encourage visual confirmation of the settings.

<Description of Editing Display Attributes> Furthermore, the input and display device 1 according to the present embodiment edits the attributes for each text,
For example, it is also possible to set the display time. This display attribute editing starts as shown in Figure 12 (step 1).
20) If there is no mode switching (determined NO in step 121), and if it is determined whether or not an item has been changed using the skip key 22 (step 122), select the item content using the up or down key 24 or 25. After (step 124), the changed attribute contents are displayed (step 125). In addition, the step 12
If no item is selected in step 2, the item number is switched in step 123 and then displayed (step 126). Even if the item contents are not changed in step 124, step 1
26 to display display attributes.

Specific key operations and display screens for this operation are shown in screens 97 to 99 in FIG. 9. That is, editing of the display attributes is performed while switching to a screen 98 as shown in screen 97 in FIG. 9 by pressing the selection key 21 when the registration of message 4 is completed. This screen 98 is a screen for setting the attribute (Attribution) of each text. If this attribute (on the right side of "=") is set as shown in Table 1 below, the display time of Text 1 (T1) will be 5. seconds, the display time of text 2 (T2) is 200 ms, the display time of text 3 (T3) is 5 seconds, and the display time of text 4 (T4) is 500 ms. Note that this display time is not limited to the following.

[0033]

[Table 1]

The attribute can be set by changing the attribute number in Table 1 using the up key 24 and down key 25 while the cursor is positioned on the texts 1 to 4 using the skip key 22. Note that the attribute 4 "infinite" means that the text is displayed continuously for an infinite time.

When the attribute setting is completed, the screen returns to the text 1 display screen as shown in screen 99 by pressing the selection key 21, and the registration is completed by storing the setting contents in the memory 44 by pressing the memory key 26. The process ends in the same manner as above.

[0036] For the four messages thus set, the operator specifies the selection switch 38 shown in FIG. 3 to sequentially display any four texts on the message display section 3. Furthermore, when the vehicle is braking, an external signal 48 is input from a circuit linked to the vehicle braking mechanism to the circuit shown in FIG. ” is displayed on the display unit 3, and the stop lamp 2 is turned on to alert vehicles behind. This circuit can similarly display the fixed text "Turn right" or "Turn left" on the display section 3 by interrupting the external signal 48 when the vehicle turns. ``Parking'' and other messages can also be displayed when the vehicle is stopped.

As described above, the input and display device according to this embodiment continuously displays a plurality of texts consisting of arbitrary character strings behind the vehicle, and when braking, etc., displays text linked to the action. can do.

[0038] In the above embodiment, an example in which the present invention is applied to a display device provided on a rear window of a vehicle has been described, but the present invention is not limited to this and can be applied to a display device having a general advertising function. Also good. Furthermore, the character fonts used in the present invention may be increased as necessary (JIS 1st and 2nd level), and the types of text may also be increased, for example, 16 types of static text and 8 types of moving text. It may be increased. Furthermore, it may be configured such that original characters/symbols/figures etc. can be registered using a font creation function. To realize this font creation function,
This can be achieved by providing ← and → keys so that the cursor can be moved in any direction on a blank screen, and by configuring the dot position designated by the cursor to be registered. This font creation function is not limited to this, but can be achieved by adding a well-known external character registration function to the CPU, such as WordFlosser.

[0039]

Effects of the Invention As described above, in the data input device according to the present invention, the control means, while displaying the number of the character string and the character position in the character string, controls the displayed character string and the character position. By selectively displaying and inputting the character/symbol font to be input, any text can be input with a simple key configuration and operation.

Further, in the data display device according to the present invention, the control means inputs the number of the character string corresponding to the display order number with a plurality of display order numbers of the character string being displayed, and By sequentially displaying a plurality of character strings in the order set in the numbers, arbitrary character strings can be displayed in the preset order.
