Problems solved by technology

Because there is a large gap between these wheels, there will be losses due to the refraction of light
Some of these prior constructions (such as the timepiece movements shown in U.S. Patent Nos. 4,645,357 and 5,566,140) included two sets of light-emitting and light-receiving elements, which increased production costs

Embodiment Construction

[0022] 1 shows a partial cross-sectional view of a timepiece movement 10 (eg, a movement of a watch) according to a first embodiment of the present invention.

[0023] The timepiece movement 10 includes an hour wheel 12 which is fixed to a hollow hour shaft 12a on which an hour hand (not shown) is fixed. The hour wheel 12 is driven to rotate by a motor (not shown) according to the change of the hour time. from figure 2 It can be clearly seen that a small opening 12b is formed near the bottom of the hour shaft 12a, the function of which will be explained below.

[0024] The timepiece movement 10 also includes a minute wheel 14 which is fixed to a hollow minute shaft 14a on which a minute hand (not shown) is fixed. The minute wheel 14 is driven to rotate by a motor (not shown) according to the minute time. The minute shaft 14a is sized and shaped to fit within the hollow hour shaft 12a for coaxial rotational movement about a longitudinal axis L-L parallel to the longitudinal ...

Abstract

A movement mechanism of clock comprises hour wheel with hour shaft fixed with hour pointer, minute wheel with minute shaft fixed with minute pointer, second wheel with second shaft fixed with second pointer, light transmitter and light receiver. The hour shaft has the first eyelet, minute one has the second eyelet and second one has the third eyelet so light transmitted out by transmitter is allowable to pass through only when wheels of hour, minute and second are on corresponding preset reference position.

Description

technical field [0001] The present invention relates to a movement mechanism of a timepiece, and more particularly, to a movement mechanism of a timepiece that can be used when the hour wheel and the minute wheel are at predetermined reference positions, such as the 12 o'clock position (ie, 12:00). Detects any difference between the time displayed at 12 o'clock and the actual time, such as the time received by the receiver of the watch from an external signal source, and corrects the time error displayed by the watch. Background technique [0002] In the past, there were many movement mechanisms of timepieces. US Patent No. 4,645,357 to Allgaier et al. discloses a timepiece capable of receiving externally transmitted radio signals corresponding to the precise time of day. A detection mechanism is provided in the timepiece for detecting the time of day displayed by the timepiece. Comparing these signals determines the accuracy of the timepiece. The detection mechanism incl...
