CHANGE OF STATE INDICATOR FOR JUMP DISPLAY MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a state indicator device that displays a transition between two stable states.

SOLUTION: A change of state indicator 2 that a state indicator device 1 of the present invention has is indirectly and discontinuously driven by a drive element 7 against elastic return means 19. The state indicator device 1 comprises a driving pinion 9 that is driven by the drive element 7. The driving pinion 9 drives a star wheel 10 in a discontinuous manner in order to control its pivoting movement to control each jump of a timepiece display mechanism 30 against a jumper 26 applied against the star wheel 10 by the elastic return means 19. The jumper 26 is formed by a beak 14 of a lever 13 and controls a pivoting movement and a return to position of the change of state indicator 2 each time the beak 14 passes between two successive tooth spaces 12 of the star wheel 10. Control of the jumper 26 is performed by means of a tooth 11 between the tooth spaces 12. The lever 13 has a first support arm 15 of the beak 14, and a second support arm 16 of the change of state indicator 2.
