ABSTRACT:
A hand-written pattern is introduced through a matrix input means and stored in a matrix memory. An alarm time is set and stored in an alarm time memory. A detection circuit develops a detection output when the current time reaches the alarm time set in the alarm time memory. In response to the detection output, the hand-written pattern stored in the matrix memory is read out and displayed on a matrix display panel.
