Abstract
Digital-analog display device for timepiece comprising a cannon pinion (1), consisting of an analog disk (2) mounted on the cannon pinion and having a window (3) through which there appears a digit carried by a digital disk (5) mounted coaxially to the analog disk (2). The digital disk is driven in rotation by the cannon pinion by jumping means and its rotation relative to the analog disk is ensured by an eccentric moveable element (12) provided with a finger (13) which drives, on each revolution, a toothed wheel (6) integral with the digital disk (5).
Claims6
A digital-analog display device for timepieces, comprising:
- a rotatable cannon pinion;
- means for rotating said cannon pinion;
- an analog disk attached to said cannon pinion, said analog disk having a window:
- a rotatable digital disk located adjacent to said analog disk;
- at least one digit located on said digital disk;
- means for rotating said digital disk relative to said analog disk, said rotating means being responsive at a predetermined point of each revolution of said analog disk, said rotating means including a toothed wheel coaxially attached to said digital disk and a moveable eccentric element which is located at a point adjacent to said toothed wheel;
- means for moving said eccentric element so that said toothed wheel rotates said digital disk at said predetermined point;
- and
- means for selectively aligning said at least one digit of said digital disk with respect to said window in response to said rotation of said digital disk relative to said analog disk.
