A rotary table driving mechanism of a coin last-in-first-out/temporary storage device comprises a base. A rotary table and a motor are arranged on the base; notches with the same number with coin storage units are arrayed on the circumference of the rotary table; each notch is adjacent to one coin storage unit; a shifting fork is connected to a motor shaft in a sleeving manner in the axial direction; shifting fork heads extend into the notches; the shifting fork heads and the motor shaft are eccentric; a raster sheet is connected to the shifting fork in the sleeving manner; the raster sheet is provided with two raster holes which form a 180-degree angle; a photoelectric sensor matched with the raster sheet is arranged at the base; the two shifting fork heads form a 180-degree angle; the motor shaft rotates to drive the shifting fork heads to act on notch walls to drive the rotary table to rotate; the shifting fork heads are not connected or meshed with the notch walls; the shifting fork heads are only in contact with the notch wall, so the machining accuracy requirement is low, the manufacturing cost is reduced, the rotary table driving mechanism is used for detecting the separation of the raster and the rotary table during rotating of the rotary table, and more installation spaces are available for the installation of a rotary control photoelectric component. |
