PURPOSE:To realize a clock having a plurality of dual time functions even in an analogue type electronic clock, by such simple constitution that slip wheels each having slip function are respectively arranged in a train wheel group reaching an auxiliary hand wheel from an hour wheel. CONSTITUTION:The third day back wheel 17 of an analogue type electronic clock with two dual time functions is meshed with the cannon pinion 9b and the second auxiliary hand wheel 11 fixed to an hour wheel 9 while the upper handle of the second auxiliary hand wheel 11 is pivotally supported by a main plate 14 and the lower handle thereof is pivotally supported by a back plate 16 and vertical movement is held by both of them. By respectively arranging slip wheels having slip functions in a train wheel group reaching the auxiliary hand wheel from the hour wheel as mentioned above, a clock having a plurality of dual time functions can be realized even in an analogue type electronic clock by simple constitution. |
