发明名称 Indicating member advancing mechanism
摘要 An electronic analog calendar timepiece includes a mechanism for automatically correcting the date indication at the ends of months having less than 31 days. A second motor activates the month correction-mechanism in short months to advance the date dial by additional indicated days. Such irregular advancements occur in accordance with the condition of switches associated with the 29th, 30th, and 31st day positions of the date dial, and in accordance with data stored in memory to correlate with the displayed month of the year. A conventional driving mechanism associates with conventional time keeping circuitry to advance the hands and the day, date, and month indicators for all days occurring in the month. The month-end correcting mechanism is linked to the conventional driving mechanism by actuation of the second motor.
