ABSTRACT:
A clock has a set of clock hands driven in accordance with a time base signal to indicate time. The time base signal is counted by a resettable counter which produces a time count value on the quarter, half and three-quarter hours to activate a melody generating circuit. Each time the clock hands reach an hour position, an hour signal is generated and fed to an hour striking circuit. During time correction of the clock hands or when electric power is initially applied to the clock, the melody generating circuit is inhibited until the next hour signal is generated, thereby ensuring that a melody will only be generated when the time count of the counter coincides with the time indication of the clock hands.
