The display control unit 6 reads the coordinate value of a point on the handwritten character pattern input by tracing the character pattern displayed on the display unit 4, for example, every 0.1 seconds to input the coordinate value. For example, an input unit such as a tablet. , 7 is a second pattern buffer that stores the handwritten character pattern input by the input unit 4, and 8 is a pattern buffer that is stored in the first pattern buffer 3 by a technique such as pattern matching. By comparing a model character patterns, the workmanship of the handwritten character patterns stored in the second pattern buffer 7 is input by the input unit 6, an evaluation unit for evaluating the overall or per stroke.

[Problems to be solved by the invention]

In the character practicing machine configured as described above, especially in the character practicing machine for young practitioners, the evaluation result cannot be given to the practitioner until the writing of one stroke or all strokes is completed, so that the point where the writing style is not good There is a problem that you cannot point out to practitioners in a timely manner.

[Means for solving problems]

According to the present invention, a pattern buffer that stores model character patterns to be practiced as coordinate values of a plurality of points arranged in a stroke order at predetermined intervals, a display unit that displays the character patterns, and a display unit that displays the character patterns are displayed on the display unit. The input unit for reading and inputting the coordinate values of the points on the handwritten character pattern that are input by tracing the model character pattern at predetermined intervals and the pattern buffer, and the point on the model character pattern from the previous input unit. The coordinate value of a predetermined number of points following the corresponding point determined to correspond to the input point is read out, and the mutual distance between one point on the character pattern input by the input unit and the predetermined number of points. If the shortest value of the distance is within a predetermined threshold value, the point with the shortest distance is determined as the corresponding point, and if it exceeds the threshold value, the corresponding point determination unit determines that there is no corresponding point. , Each time the points on the handwritten character pattern are input one by one from the input unit, the corresponding point determination unit determines the presence or absence of corresponding points on the model character pattern, and in accordance with this presence or absence, By displaying on the display unit, the problem is solved.

[Action]

That is, first, by designating the character to be practiced by the designating unit 1, the pattern is stored in the pattern buffer 3 and simultaneously displayed on the display unit 4.

Next, let the practitioner write the letters, and input, for example, 0.
For each point on the handwritten character pattern input every second, from the points stored in the pattern buffer 3,
Corresponding points are obtained with the distance between them being less than or equal to a predetermined threshold.

As a result, when corresponding points are obtained, the points on the input handwritten character pattern are displayed by connecting them with a straight line in the order of input, for example, by a broken line.

In addition, when the corresponding points are not obtained, that is, when the handwritten character deviates greatly from the model character pattern by exceeding the threshold value, the polygonal line is not displayed and the polygonal line is displayed in a different display color. This is to point out to the practitioner in a timely manner the points that are not well written.
