<p>PROBLEM TO BE SOLVED: To realize a writing trace output device which can output traces being written on a writing face for each writing region in an order to written times. SOLUTION: When a CPU detects that a writing start indication button 14c is turned on (S13: Yes), an increment of '1' is performed for a row number (n) (S18), the trace is detected until the turning on of a writing completion button is detected (S22), and when the turning on of the writing completion button is detected (S42: Yes), trace data for one row is stored (S44). The processings of S13-S44 are executed for each row, and written rows are stored in a storage region in an order of written times. Then, the turning on of a display button 25 is detected (S46: Yes), the stored trace data is read and displayed in the stored order (S50, S52).</p> |
