Claims

[Claims for Utility Model Registration] (1) An oscillator, a time counting circuit driven by the oscillator, and a time counting circuit connected to the time counting circuit;
a first display means for displaying the minutes, a second display means for displaying the day of the week, and an hour decoder and a minute decoder connected to the first display means and for converting signals from the first display means into digital format. and a storage device which receives each signal from the hour decoder and the minute decoder and has a plurality of input/output and control pins, and a plurality of flip-flops and control switches connected to the inputs of the storage device. a setting circuit that presets the time to perform the operation; a sound generator and drive interface that are connected to each output of the storage device and perform sound notification by the storage device; a switching circuit connected to the control pin and inhibiting the function of the storage device on the date displayed on the second display means; and a switching circuit connected to the time counting circuit and the time displayed on the first and second display means. A digital clock that makes an audible notification at a set time, comprising a time setting switch that performs manual adjustment. (2) The second display means includes a counter connected to the output of the clock counting circuit, a plurality of LEDs,
2. The digital timepiece according to claim 1, further comprising a push button switch for adjusting the date displayed on the second display means. (3) A storage device connected to the address bus of the storage device and having two switches in order to increase the number of storage blocks each storing music software for making a notification via the sound generator at a set time. A digital watch according to claim 1, characterized in that it is equipped with a selection means.
