PROBLEM TO BE SOLVED: To provide an electronic clock capable of suppressing increase of a size or cost and enabling a quick operation while preventing a wrong operation.SOLUTION: An input part 104 receives an input operation. A CPU 101 changes an operational mode according to a mode change instruction input received at the input part 104. The CPU 101 operates according to the set operational mode. After changing the setting of the operational mode, if the input part 104 has not accepted a predetermined time input, the CPU 101 puts the setting of the operational mode back to the operational mode before the change. |
