| 摘要 |
<p>The present invention relates to a device for lash free positioning of especially components used in optical and optoelectronical equipments relatively to a fixed reference unit (29) using at least two interconnected elastic blocks (11, 12) each consisting of two base elements placed at a distance from each other and interconnected by elastic elements (17, 19), constituting a cantilevered system as related to one of the base elements. To the system a holder (22) is attached, on which the components to be positioned are fixed, that each elastic block (11, 12) is essentially rigid along a main axis (z) of the elastically undeformed cantilevered system, and is elastic in directions perpendicular to the axis, that the device has mechanisms for adjustment which apply adjustable forces between the basic element (13), or between some other to the latter fixedly joined element, and the cantilevered system or an arm fixed to this system, which latter may be the holder (22), acting in chosen directions, which translate or turn the component holder (22), when the elastic elements (17, 19) are elastically deformed.</p> |
