It consists of a group of function / mode keys such as a cancel key (25).

The monitor display (3) is composed of, for example, a dot matrix type liquid crystal display, and the storage means (4) is a so-called IC card (a semiconductor memory is fixed to a substrate so as to be detachably attached) so as to be detachable. Backed up as necessary, for example, Japanese Patent Publication No. 53-6491 or Electronic Technology Magazine 1986, No. 8, p. 79) is used.

As shown in FIG. 3, such a display information input device mainly comprises a microprocessor (central processing unit) (61) for 16-bit parallel processing, for example.
In FIG. 3, (62) is an I / O port for controlling the handwriting input unit (1), (63) is a key encoder for controlling the keyboard (2), (31) is a driver for a monitor display, Reference numerals (71), (72), and (73) denote a read-only memory for storing a program, a read / write memory for a work area, and a font memory for storing dot information of a registered display.

In such a configuration, the display body is represented by a 32-bit code as shown in FIG.
Six bits are assigned flag bits indicating a character type (character or format mark such as indent) (3 bits), a character color (2 bits), and a background color (2 bits), and the remaining 16 bits are characters. Indicates the code. Thus,
When the power is turned on, the microprocessor (61) executes the program in accordance with the memory (71), but first checks the operation of the keyboard (2) in the text creation (registered display body input) mode. And when there is an input from the keyboard (2),
A predetermined code is stored in the storage means (4) in accordance with the character color and the background color determined by the color designation key (22). Next, when it is desired to input an unregistered display, the user operates the handwriting input key (23) and the color designation key to designate a desired color (changes from red to green to yellow according to the number of operations). This allows the microprocessor (6
1) accesses the I / O port (62) and
The / O port (62) calculates the matrix position when the key contact scanned by the key is closed, and inverts the state of the matrix position corresponding to the designated color. For example, if not touched at all, the state is "L" at all matrix positions, and if any operation is performed, the matrix position corresponding to the color becomes "H". As described above, the I / O port (62) has a matrix register (for red and green) corresponding to the matrix position, and its output is provided for each chip of the light emitting elements (12), (12). In the "H" part, the chip of the light emitting element (12) corresponding to the color of the register is turned on. When the shape of the unregistered display object has been corrected, the handwriting input key (23) is operated again. Then, the microprocessor (61) detects the number of the unregistered display object, and sets a code corresponding to a code equal to or more than a predetermined value (less than the predetermined value represents the registered display object) as a character code, and stores the code. It is stored in the means (4) (in this case, the character type, character color, and background color flag are set to 0). And
The head address for storing the dot information is calculated based on the code, and the output data of the matrix register of each color of the I / O port (62) is stored in the storage means (4) as the dot information. FIG. 5 shows a flowchart of a main part program in the monitor mode written in the program memory, and the operation will be described below based on the flowchart. First, when the user operates the monitor key (24), the microprocessor (61) operates the storage means (4).
From the font memory (74) if it is a registered display, and dot information from the storage means (4) if it is an unregistered display, and display it on the monitor display (3) (step). S-1, 2) (see FIG. 6). Next, it is checked whether or not the keyboard (2) is operated. If the cancel key (25) is operated, this mode is ended. If the cursor keys (21), (21). Move the cursor (step S-3,
4). Thereafter, the position of the cursor is checked, and the character type of the display corresponding to this is checked (step S-).
5, 6). If this display is other than a format mark, it is checked whether or not it is a registered display (step S-).
7). Here, in the case of a registered display body, the dot data read from the font memory (73) is calculated and generated as dot data for red and dot data for green according to the character color flag and the background color flag. The data is provided to the I / O port (62) (steps S-8, S10). As a result, each of the light emitting elements (12) and (12) displays the display body in color. In the case of an unregistered display, the red dot data and the green dot data stored in the storage means (4) are directly input to the I / O port (6).
2) (Steps S-9 and S10). This allows
As described above, each of the light emitting elements (12) and (12) displays the display body in color.

FIG. 7 shows a monitor display according to another embodiment of the present invention, which will be described below. Other configurations are the same as those in FIGS. 1 to 3. The monitor display (3) comprises a message display (3A) and a color display (3B). The color display section (3B) displays the character color (a) and the background color (b) with the characters "red", "green", and "yellow".

When the monitor mode similar to that described above is executed, the microprocessor (61) determines whether the display corresponding to the cursor is a registered display according to the character color flag and the background color flag, respectively. Light emitting element (12) (1
2) The display is colored in... And the color display section (3
B) displays the character color and the background color. Thereby, the color of the display can be recognized by both the color display (3B) and the handwriting input unit (1). Also, at this time,
Using the cursor keys (21), (21), the cursor is moved to the color display section (3B) beyond the margin to be positioned on the character color (a) or the background color (b), and the color designation key (22) is pressed. When operated, the display changes from red to green to yellow. Thus, the character color flag or the background color flag is changed to that color, and the output of the matrix register of the I / O port (62) is changed according to the changed flag, and the light emitting element (12) (12)... Are displayed in the changed color.

Next, if the display corresponding to the cursor is an unregistered display, the microprocessor (61) executes the red dot data and the green dot data stored in the storage means (4) in the same manner as described above. Light emitting element (12) based on dot data of
(12) is caused to emit light. And a color display section (3B)
Is displayed as “*” in both the character color and the background color to indicate that it is an unregistered display. This is because, in the case of an unregistered display, the above-mentioned display cannot be performed because the character color and the background color cannot be distinguished. In this state, the movement of the cursor to the color display section (3B) is prohibited, and the color cannot be changed.

[0014]

The present invention is constructed as described above. In the monitor mode, if a predetermined display is designated on the monitor display, the color display is made on the handwriting input means. Therefore, it is possible to monitor the color tone confirmation.
