Abstract

PURPOSE:To make the mechanism small-size and to position lenses with a high precision, by using a Geneva mechanism consisting of the combination of arms and pins as a transfer driving mechanism for positioning lenses. CONSTITUTION:A tureet drum 3 having plural lenses 1 and 2, positioning means corresponding to these lenses, and a repetitive rotating means at a constant angle is supported axially through a rotating means by a pair of supporting plates 7 and 8 fixed to a fitting plate. A position detecting part and a shaft 11 having an arm 13 engaged with the repetitive rotating means at a constant angle are turnably supported axially by the supporting plate 7, and an arm 14 having a meshing holding means and a meshing releasing means is fixed axially to an eccentric shaft 15, and this eccentric shaft 15 is so supported axially by the supporting plate 8 that the arm is meshed with the positioning means; and the movement of the axis due to turning of the eccentric shaft 15 is transferred to the turret drum 3 through the arm 14, thus adjusting the rotation of the turret drum 3 minutely.
