  • Patent number: 5619478
    Abstract: An analog electronic timepiece having a function by use of which a plurality of predetermined times as well as a mode change can be visually informed so that they are easily understood by hand movement and sound generation. When a judgement circuit judges a predetermined condition of the timepiece, such as time coincidence with a preset alarm time and/or mode change, the judgement circuit outputs a starting signal of the hand movement and sound generation. An information signal generation circuit produces timing signals for driving the hands and generating sound in response to the starting signal. An information signal generating circuit outputs an operation generation signal to a motor driving circuit and/or a sound signal generating circuit according to preselected numbers of hand movement operation steps and frequencies of sound generation read out from an information operation storing circuit.
