Abstract

PURPOSE: To improve alarm announcement percision for alarm set time by providing a leaf press spring and a minute lead contact mechanism to one part of a minute leaf and then by starting alarm announcement when an alarm contact and minute contact are both closed.
CONSTITUTION: Turning force from motor 11, after being reduced by train wheel 12, turns minute display wheel 14 and further turns hour display wheel 20, displaying the current time. Minute leaf contact 30 consists of minute leaf 18 with arranged electric connection part 19, and minute leaf press springs 31 and 32. Leaf 18 is updated at the alarm set time and springs 31 and 32 are connected to connection part 19, closing contact 30. Alarm contact 13 is included in alarm mechanism 40 and contact 13 is opened and closed by coupling with train wheel 12. Therefore, alarm announcement unit 50 is supplied with an operating signal with contacts 13 and 30 closed to start operation.
