<P>PROBLEM TO BE SOLVED: To provide a clock device in which means for detecting time to be announced is rationally constituted. <P>SOLUTION: A clock device in which means for detecting time to be announced is configured to detect a rotational position of an hour chiming wheel by the operation of a photoreflector 330 every revolution of a minute hand pipe, comprises a sensor substrate 400 mounting the photoreflector, and a flat-shaped case body 500. A speed reduction mechanism 110, a base end part of a minute hand pipe 120, motion works 140, a base end part of an hour hand pipe 130, and a one-revolution detection mechanism 310 are arranged between a first case member 510 and a second case member 520; an hour chiming wheel 320 rotating synchronously with the hour hand pipe is arranged between the first case member and a third case member 530; the sensor substrate is arranged on the front side of the third case member; the first case member, the third case member, and the sensor substrate respectively include through holes 511, 531, and 401 which the minute hand pipe and the hour hand pipe pierce; and slits 532 are provided on the third case member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
