Abstract
(EN)
An apparatus for driving a reflector for OIS by using a wire according to the present invention comprises: a support frame in which two or more shape memory alloy (SMA) wires are disposed at different positions; a reflector installed in the support frame and changing the path of light entering through an opening so as to allow the light to be incident to a lens; a base frame to which the SMA wires are coupled; an elastic body disposed between the support frame and the base frame so as to elastically support the support frame; and a circuit board for supplying current to the SMA wires.
(FR)
Un appareil pour commander un réflecteur pour une stabilisation optique de l'image (OIS) à l'aide d'un fil selon la présente invention comprend : un cadre de support dans lequel deux ou plusieurs alliage à mémoire de forme (AMF) des fils sont disposés à différentes positions; un réflecteur installé dans le cadre de support et changeant le trajet de lumière entrant à travers une ouverture de façon à permettre à la lumière d'être incidente sur une lentille; un cadre de base auquel les fils AMF sont couplés; un corps élastique disposé entre le cadre de support et le cadre de base de façon à supporter élastiquement le cadre de support; et une carte de circuit imprimé pour fournir du courant aux fils AMF.
