PURPOSE:To prevent schedule content from being known by another person, by a method wherein only the presence of a schedule is displayed in usual and, if necessary, a keyboard is manipulated to display schedule content while reading out the same. CONSTITUTION:The schedule from a keyboard 2 is recorded by a recording means M. When the coincidence of the data region m1 of the recording means M and the data from a clock circuit is detected by a coincidence detecting circuit E, a CRT display apparatus 11 displays that a registered schedule is present. A gate circuit G is opened on the basis of the order from the keyboard 2 and the schedule content of the day wherein the presence of the registered schedule is displayed is read from a content region m2 and displayed by the CRT display apparatus 11. |
