<p>PURPOSE:To improve an educational effect by entirely erasing the information or leaving a part, by reading out handwriting information of a character, a pattern, etc. in order of a write time and in reverse order from a recording device. CONSTITUTION:To a digitizer which is not shown in the figure, a character, a pattern, etc. are inputted by handwriting with a stylus pen, and are stored in an external memory 7. For instance, a character A is stored in order of write 10, 11 and 12. As for a data of this external memory 7, vector data detection 15 is executed, a contact of a switch 16 is connected to 16-1, vector dot conversion 4 is executed, and A is displayed 6 through a refresh memory 5. Subsequently, the external memory 7 is read out in the reverse direction through a reverse direction register 18, and when vector data detection 19 is executed, vector dot conversion 4 is executed through a contact 16-2 of the switch 16, and the character A is erased as 12, 11 and 10 in reverse order through the refresh memory 5. When only 10 is left, read-out of memory is stopped at 10. In this way, an educational effect of write order is elevated.</p> |
