second embodiment

Reference is now made FIG. 24 wherein a multifunction electronic analog watch, generally indicated at 100', constructed in accordance with the invention is provided. Like structures are indicated with like numerals, the difference in embodiments being that in multifunction electronic analog watch 100' three step motors are utilized to provide multifunction operation.

Step motor D 32 has been removed from electronic analog watch 100 along with the alarm function and timer function. Additionally, AL intermediate wheel 34, AL minute wheel 35, AL minute wheel and pinion 36, AL hour wheel and pinion 37, second stem 23, AL hour wheel and pinion 37, second stem 23, AL drum wheel 49, AL pinon 51, switch .[.C26.]. .Iadd.C 26 .Iaddend.and second setting lever 59 are also removed as not being required for analog electronic watch 100' which does not have the alarm function. Further, in watch 100 a small wheel 13 was positioned on an axis at the nine o'clock position of the watch movement. Accord...

Abstract

A multifunction electronic analog timepiece includes a face and a plurality of indicators positioned on the face for displaying at least two time keeping functions. At least two step motors are provided for driving the plurality of time keeping function indicators. The time keeping function indicators are arbitrarily disposed about the face dependent upon the number of step motors and position of step motors required to drive the indicators. A microcomputer is provided and includes a program memory for storing software instructions for controlling the step motors.

Description

BACKGROUND OF THE INVENTIONThe present invention relates to an electronic analog timepiece, and in particular, to an electronic timepiece having multifunction indicators such as chronograph indication, timer indication and elapsed time indication.To meet consumer demand, electronic analog timepieces such as watches have been manufactured having multifunctions such as chronograph, alarm, elapsed time and the like. Multifunction electronic analog watches are known from Japanese Patent Laid Open Nos. 286783 / 86 and 294388 / 86 and Japanese Utility Model Laid Open No. 26191 / 86 and include a small second hand, alarm hour / minute hands and other analog indicators in addition to twelve hour second, hour and minute hands. A small window for exclusive multifunction use is provided at arbitrary positions on the watch face for example, at the six o'clock watch face position, or some other position to indicate a special non-time keeping function such as the alarm time. Additionally an auxiliary ste...
