Abstract:
1. A mechanical change of state indicator device for a semi-instantaneous or instantaneous display mechanism by jumps of a given magnitude driven by a drive element of a movement or a timepiece, wherein for the display of a transition between two stable display states of said given magnitude said device comprises a change of state display indicator, which is movable in relation to a supplementary change of state display, wherein said device includes elastic return means formed by at least one spring applied against a lever included in said device, and wherein said indicator is driven indirectly and discontinuously by said drive element against elastic return means, wherein said device comprises a driving pinion fitted to be driven directly or indirectly by said drive element, wherein said driving pinion drives a star wheel in a discontinuous manner in order to control a pivoting movement of said star wheel to control each jump of said semi-instantaneous or instantaneous display mechanism against a jumper applied against said star wheel by said elastic return means and said jumper is formed by a beak of said lever, said lever controlling a pivoting movement and a return to position of said indicator each time said beak passes between two successive tooth spaces that said star wheel comprises by means of a tooth located between said spaces, said lever comprising a first support arm and a second support arm, said first support arm supporting said beak, and said second support arm arranged to support said indicator or to control the displacement of said indicator which is formed by a change of state display flag, which is movable in relation to said supplementary change of state display formed by a change of state aperture, and wherein said flag comprises a first sector indicating a transition in progress and a second sector indicating a stable state of the display without transition in progress.
