Claims

[Scope of utility model registration request]

(1) An hour wheel that rotates once every 12 hours in conjunction with the clock train, a guide setting wheel that is coaxially arranged with the hour wheel and can set any guide time, and a space between the hour wheel and the guide setting wheel. A guide device including a guide cam disposed coaxially so as to be rotatable and slidable in the axial direction, and a biasing spring for urging the guide cam toward a guide setting wheel. A time cam hole is bored in either one of the standard cam planes facing the cam plane, and a time cam protrusion is provided on the other side, which can be constantly engaged with the time cam hole, and - the end edge is formed as an inclined surface. is formed, a guide cam hole is formed in either one of the guide setting wheel plane and the guide cam plane facing the guide setting wheel, and the other is capable of engaging with the guide cam hole, A guide cam is formed whose edge is an inclined surface, and when the hour wheel or guide setting wheel is rotated in the opposite direction, the guide cam is activated by engaging the inclined surface of the hour cam protrusion and the edge of the hour cam hole. 1. A timepiece reference device, which is slidable in the axial direction to release the engagement between a reference pawl and a reference cam hole, thereby making it possible to correct the forward and reverse rotation of an hour wheel or a reference setting wheel.

(2) Utility Model Registration In the device according to claim 1, the time cam hole formed in the time wheel or reference cam faces the inclined surface of the cam protrusion when engaged with the time cam hole. A clock reference device characterized by an inclined edge formed on the left side.

(3) Utility model registration Claim In the device described in claim 1, the hour cam protrusion formed on the hour wheel or the reference cam always passes through the hour cam hole formed in the reference cam or the hour wheel. A clock reference device characterized by:

(4) A timepiece reference device according to claim (1), wherein the hour wheel and the reference setting wheel are provided at different axial positions from the time indicating hand axis.

(5) A timepiece reference device as set forth in item (1) of the scope of the utility model registration claim, wherein the hour wheel and the reference setting wheel are provided coaxially with the time indicator hand shaft.・
