Clock e.g. stop clock, has actuator to move driver unit according to hysterisis movement generated by two actuation modules so that driver unit sequentially gears with successive teeth of cogwheel
The clock has a cogwheel (10), a driver unit to sequentially gear with the cogwheel (10), and an actuator (20) to move the driver unit according to a hysterisis movement so that the driver unit gears with successive teeth of the wheel. The actuator (20) has two actuation modules that are simultaneously controlled to generate a combined hysteresis movement of the driver unit. The actuation module moves the driver unit in a direction with respect to the wheel (10) and the actuation module moves the driver unit in another direction with respect to the wheel (10).
