PURPOSE:To obtain the sound reporting device whose power consumption is small and which can be incorporated in compact electronic wrist watches, by reporting pace sound only during a specified time period at every memorized time set in a memory means. CONSTITUTION:Pulses which are outputted at every one minute and the like from a time measuring counter 44 are counted by a counter 61. Every time the result is agreed with a preset time such as 20min which is set and stored in a period setting counter 59 in a time memory means, an FF64, which is reset by a decimal notation counter 67 by the agreed output of a coincidence circuit 60 at every 10sec and the like, is set. An AND gate 56 is opened by said set output. The pace sound reporting signal having the frequency corresponding to the setting of a pace selecting counter 48 is outputted from a pace signal selecting circuit 42 through the gate circuit 56. The pace sound is reported only during a specified time period such as 10sec every time a time period such as 20min and the like has elapsed and the reporting is automatically stopped. In this low power consumption constitution, the pace sound reporting device, which can be incorporated in the compact electronic wrist watch, is obtained. |
