Abstract
PURPOSE: To enable low-load and yet fast correction to be performed by providing a calendar feed pinion which is normally stopped of revolution with its tooth tips being held contacted to the outside circumference of a date cam and is driven only when engaged with the protrusion of the cam.
CONSTITUTION: A date cam 9 which moves cooperatively and coaxially with a date wheel 6 making 1 turn a day, has a protrusion 11 on its outside circumference 10 and whose outside circumference or entire part elastically displaces is provided, and a date and day calendar feed pinion which is driven only when intermeshed with the protrusions 11 of said outside circumference 10 is provided and is intermeshed with a date dial 17 and a daily star 22, whereby calendar display is effected. Here, every time when the protrusion of the date cam 9 acts one turn, it turns the calendar feed pinion for two teeth and also moves the date dial 17 and daily star 22 for two teeth, thereby moving these for one day. When the calendar feed pinion is rotated from the outside by a fast correcting device, the date cam outside circumferential part 10 is displaced for the interference length with the calendar feed pinion by the displacement of an elastic arm 14, whereby the teeth of the calendar feed pinion are allowed to pass. Thereby, low-load and yet fast correction may be performed without using any spring.
