Claims

[Claims for Utility Model Registration] (1) The output displacement of a primary drive displacement generating means, which is a single drive force generation source, is converted into a secondary drive displacement by a single displacement transmission system using a plurality of displacement transmission elements or a single displacement transmission element. A predetermined positional relationship is established by a pre-stage displacement transmission system that transmits the output displacement of the secondary drive displacement generation means to the generation means, and a plurality of systems of displacement transmission elements each including a single displacement transmission element whose backlash is sufficiently small. 1. An optical element driving device comprising: a rear-stage displacement transmission system that transmits transmission to each of a plurality of movable optical elements to be displaced; (2) The optical element driving device according to claim 1, wherein one of the movable optical elements is a macro conversion lens and the other is a strobe diffuser. (3) The secondary drive displacement generating means and the rear-stage displacement transmission system are configured such that displacement transmission from the former to the latter constitutes a displacement conversion system that converts rotational displacement into linear displacement, and each of the movable optical 2. The optical element driving device according to claim 1, wherein the predetermined displacement position of the element substantially corresponds to a dead center of the displacement conversion system.
