Abstract

PURPOSE:To simplify the construction by detecting the plural step operations of a first hand so that the second hand may be stepwise operated. CONSTITUTION:A first indesing disc 6, which is formed with projections 10 and 10' at its pentagonal positions, is fixed to the shaft 5 of a step motor 1. A second indexing disc 7, which has its side formed with 120 teeth 13 and an hour hand 3 attached thereto, is rotatably fitted on the motor shaft 5. Moreover, a minute hand 2 is fixed to the motor shaft 5. The first and second indexing discs 6 and 7 are connected in a driven manner through an intermediate gear 8. As a result, if the step motor 1 is driven, the shaft 5 is turned one step for each minute so that the minute hand 2 effects the minute indication. At the same time, the hour hand 3 is turned through the first disc 6, the intermediate gear 8 and the second disc 7 thereby to effect the hour indication. As a result, a complex gear train mechanism can be dispensed with, but the desired objects can be attained.
