Abstract
Abstract A timer for controlling an operation start and/or end of an electrical apparatus at a manually input operation time. The timer includes a clock having an active state and a nonactive state, which generates a current time in the active state. A reset circuit sets the clock to the nonactive state. Entering an initial time to the clock sets the clock to the active state. The timer has two operating modes. In one mode, the operation time is designated by a target time. In the other mode, the operation time is designated by a time interval. The operating mode is automatically changed based on the state of the clock. If the clock is in the active state, the operation time is designated by the target time. In the nonactive state, the operation time is designated by the time interval.
