Layers adjusted portable mechanical clock tray, has clock gears to be automatically detected and corrected by using layer-dependant gear deviation, temperature-dependant gear deviation of clock and rotational torque of lift spring

摘要

The tray has clock gears to be automatically detected and corrected by using layer-dependant gear deviation, temperature-dependant gear deviation of a layers adjusted portable mechanical clock, rotational torque of a lift spring dependant on gear deviation of the clock, optical acquisition of pointer position by using an electronic camera, acquisition of a pointer position of second or minute hand by using a reflectance light cabinet, a proximity switch or a sensor, acoustic acquisition by switching noises, and acoustic acquisition of spleen noises.
