Embodiment 1
[0051] Such as Figure 1 to Figure 4 , a grooved copybook, comprising a copybook board 10. The board surface of copybook board is provided with font outline 11, and font outline is the outline of soft pen copybook font. In this embodiment, the glyph outline is taken as an example of the vertical strokes of calligraphy European fonts, and the vertical strokes of European fonts are mostly slightly thicker at the top and bottom, and slightly thinner at the middle. In this embodiment, the minimum width K of the glyph outline in the middle is 8.8 mm.
[0052] A font groove 20 is provided in the font outline, that is, the font groove is recessed into the copybook board along the font outline. The glyph groove stretches into the copybook board along the slope 21 from the glyph outline. The slope of font groove meets at the bottom, and the groove bottom of font groove forms a bottom intersection along 22 in copybook board. In this embodiment, the angle of the slope is α=50° (the a...
Embodiment 2
[0056] Such as Figure 5 , one A kind of groove copybook. This embodiment is an improvement of the first embodiment.
[0057] In order to reduce the depth that the font groove 20 stretches into the copybook board 10, the groove bottom of the font groove forms a converging edge that is provided with rounded corners 23 in the copybook board. The radius r of the rounded corner is smaller than the radius R of the ball head 40 of the pen, so that the ball head keeps in contact with the inclined surfaces on both sides of the glyph groove.
[0058] Such as Image 6 , Another kind of structure is, the groove bottom of font groove forms a converging edge that is provided with bottom plane 24 in copybook board. The width S of the bottom plane can not be too large, so that the surface of the ball head is higher than the bottom plane when the surface of the ball head keeps in contact with the inclined surfaces on both sides of the font groove, so as to avoid the contact of the ball h...
Embodiment 3
[0061] Such as Figure 7 , a grooved copybook pen, the grooved copybook pen of the present embodiment is applied to the grooved copybook described in embodiment one or embodiment two to carry out writing exercises, that is, the grooved copybook described in embodiment one is adopted A pen with a ball tip.
[0062] The groove copybook pen comprises a penholder 40, and the front end of the penholder is provided with a ball head 30.
[0063] In this embodiment, the diameter d of the ball head is 6 mm, which is smaller than the minimum width K of the glyph outline. Ball head can stretch in the font groove 20 of groove copybook, and the outer diameter of ball head contacts with the inclined-plane of font groove both sides.
[0064] Such as Figure 13 , the practitioner uses the grooved copybook pen of the present embodiment, and the ball head moves along the font groove according to the stroke order, and the ball head can move horizontally and up and down along the writing path ...
