アツプ送り機構。[Claims for Utility Model Registration] (1) A substrate, a pick-up mounting plate slidably attached to the substrate, a feed motor attached to the substrate, and a feed screw rotated in forward and reverse directions by the feed motor. a feed nut member that engages with the feed screw within the pick-up movement limit and slides the pick-up mounting plate;
The return spring part is elastically deformed between the board and the feed nut member or the pick-up mounting plate, and biases the feed nut member or the pick-up mounting plate in a direction opposite to the feeding direction, and the return spring part is elastic. A pick-up feed mechanism characterized in that a deforming position and a disengagement position between the feed screw and the feed nut member are made to coincide with each other. (2) The feed screw is continuously formed with at least a threaded portion and a non-threaded portion having a diameter substantially the same as the root diameter of the threaded portion, and when the feed screw and the feed nut member are in a disengaged state, 2. The pick-up feed mechanism according to claim 1, wherein a feed nut member is brought into contact with said non-threaded portion.
