Here, the configuration of the pen pressure value table 33a will be described with reference to FIGS. 3 (A) and 4 (A).
FIG. 3A is an explanatory diagram showing the structure of the pen pressure value table 33a, and FIG. 4A shows the types of character forms set in the pen pressure value table 33a shown in FIG. 3A. FIG. The pen pressure value table 33a is configured by associating the average value P (mg / mm ² ) of the detected pen pressure values with the type of character form. When 0 ≦ P <100, the character form Is selected as the normal font (see FIG. 4A),
If 100 ≦ P <200, a character form in which an underline is displayed below the character is selected (see FIG. 4A), and 200 ≦ P
In the case of, a bold character (see FIG. 4A) is set.

Next, the processing from the pen pressure detection to the character display executed by the CPU 16 will be described with reference to the flowcharts of FIGS. FIG.
FIG. 6 is a main flowchart showing main processing executed by U16, and FIG. 6 shows steps (hereinafter, referred to as S) in FIG.
FIG. 7 is a flowchart showing a character input process executed in the input / output control of 100, and FIG. 7 is a flowchart showing a character form selection process executed in S116 of FIG. First, when the person who operates the electronic organizer 10 (hereinafter, referred to as an operator) detects that the tip of the pen 12 has been put on the tablet 20 (pen down) (S102: Yes), the CPU 16 proceeds to S104. Until the tip of the pen 12 is separated from the tablet 20 (pen-up), the coordinate value of the point at which the tip of the pen 12 is in contact with the tablet 20 is determined based on the detection signal output from the coordinate value detection circuit 42. Is detected (S106), and
Based on the detection signal output from the pressure sensor 28, the magnitude of the pressure at which the tip of the pen 12 presses the surface of the tablet 20, that is, the pen pressure value is detected (S108). These detected coordinate values and pen pressure values are temporarily stored in the working RAM 40.

When pen-up is detected (S104: Yes), the CPU 16 reads the pen pressure value temporarily stored in the working RAM 40 and calculates the average value P of the read pen pressure values of one stroke. Yes (S11
4). Subsequently, the CPU 16 executes a character form selection process for selecting the form of the character to be displayed (S11).
6).

Here, the character form selection processing executed by the CPU 16 will be described with reference to the flowchart of FIG. When the CPU 16 determines that the average value P calculated in S114 is 0 ≦ P <100 (S118: Yes), the CPU 16 refers to the pen pressure value table 33a (FIG. 3 (A)) to determine the character form. A normal font is selected (S120). Also, the CPU 16 determines that 100 ≦ P
If determined to be <200 (S118: No,
S122: Yes), the pen pressure value table 33a (FIG. 3)
(A)), a character form in which an underline is displayed below the character is selected (S24), and if it is determined that 200 ≦ P (S118: No, S122: No, S126: Y)
es), referring to the pen pressure value table 33a (FIG. 3A), select bold display as the character form (S128).

Then, the CPU 16 returns to the character input processing shown in FIG. 6, performs input processing for the second and subsequent strokes (S130), and determines whether input of one character has been completed (S132). This determination is, for example, detection of the absence of pen input for a certain period of time or more, if a recognition button for performing recognition is provided, detection of that recognition button being pressed by the pen, or This is performed based on detection of the start of character input in the next input frame. Subsequently, when the CPU 16 determines that the input of one character is completed (S132: Yes), the CPU 16 performs character recognition on the input one character (S134), and selects a font corresponding to the recognition result, that is, a font in S116. The font corresponding to the character form is read from the font data storage unit 31 and displayed on the recognition result display unit 21 (S136). When there are a plurality of characters displayed on the recognition result display unit 21, a desired character can be selected by touching the tip of the pen 12 on the character, and the selected character is displayed on the editing screen. 22 is displayed.

For character recognition, for example, a stroke is created from one character coordinate value temporarily stored in the working RAM 40, and the stroke and the recognition dictionary 32 are created.
This is performed by matching with the basic stroke stored in (FIG. 2) and extracting characters having a high degree of matching. If pen down is not detected in S102, the CPU 16 performs other processing, for example, processing of another menu such as editing (S110).

As described above, if the electronic organizer 10 of the first embodiment is used, it is displayed on the recognition result display section 21 only by increasing or decreasing the magnitude of the pen pressure applied to the tablet 20 by the tip of the pen 12. You can select the character format. That is, unlike the related art, there is no need to perform an operation of designating a displayed character with a cursor or the like and an operation of pressing an icon for changing the character shape with a pen, so that the character shape can be changed without hassle.

Further, the threshold value of the normal font and the underline display is P1, and the threshold value of the underline display and the bold display is P2. When the CPU 16 detects that the pen pressure change button 53 has been pressed (S150: Yes)
s) As shown in FIG. 8, the display content of the edit screen 22 is switched to the pen pressure change screen 56 (S152). Then, CP
U16 determines whether either the threshold value P1 or the threshold value P2 has been selected (S154). Which threshold is selected is displayed by a cursor 57, for example, as shown in FIG. 8, and the cursor 57 is moved by placing the pen 12 on the screen.

Subsequently, the CPU 16 detects that the threshold value has been selected (S154: Yes), and detects that the plus button 54 has been pressed (S156: Yes).
s), the threshold value selected in S154 is increased (S
158). The manner in which the threshold value is increased or decreased is displayed by a meter 58 constituted by cursors, as shown in FIG. 8, and the greater the number of black cursors, the greater the threshold value. When the CPU 16 detects that the minus button 55 has been pressed (S156: No, 160:
Yes), the threshold selected in S154 is reduced (S162). When the CPU 16 detects that the pen pressure change button 53 has been pressed (S164: Ye)
s) The threshold set in the writing pressure value table 33a is rewritten to the changed threshold (S166), and the writing pressure changing process ends.

As described above, if the electronic notebook 10 of the second embodiment is used, the threshold value set in the writing pressure table 33a can be changed in accordance with the individual difference in writing pressure. The selection of the character form can be performed accurately.

By the way, in each of the above-described embodiments, three types of character forms, that is, normal font, underlined display, and bold display are used.
Although the case of selecting from the types of character forms has been described, FIG.
