Title:
MECHANISM FOR SETTING RATE OF TIMEPIECE OSCILLATOR
Document Type and Number:
Japanese Patent JP2017026607
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable setting and fine adjustment of a function of a mechanical timepiece, without having to open a timepiece case.SOLUTION: A microsystem 10 includes a wheel/inertia block 20 including an off-center unbalance 22 and a toothing 21 and arranged to pivot with respect to a base plate of the microsystem. The microsystem includes an actuator driving a first active click 38 arranged to drive the toothing 21, and includes means for stopping the toothing 21 in position. The actuator is a thermomechanical actuator 30 arranged to convert a flow of light energy into a displacement of a distal end of the thermomechanical actuator 30. The distal end carries the first active click 38 or directly controls a movement of the first active click 38. The microsystem 10 is capable of being incorporated in a watch including a crystal transparent to predetermined wavelengths ranges. The crystal allows passage of a light ray to regulate the microsystem 10.SELECTED DRAWING: Figure 3
