Abstract
(EN)
This optical scanning device (1) has: a main movable part (10); a pair of main torsion beams (21 and 22) that are disposed opposite each other on both ends of the main movable part (10), pivotably support the main movable part (10), and are capable of torsional deformation; and a main drive unit (30) that pivots the main movable part (10). The main movable part (10) has: a mirror part (11) provided with a reflecting surface (11a) that reflects light; and a pair of permanent magnets (12 and 13) disposed opposite each other with the mirror part (11) interposed therebetween, each of which extends along the pivot axis (X-X) of the main movable part (10). The main drive unit (30) has: yoke parts (31, 32, 33) arranged so as to surround the permanent magnets (12 and 13) along the pivot axis (X-X) of the main movable part (10); and coils (34) that are wound around the yoke parts (31, 32, 33), and when energized, excite the yoke parts (31, 32, 33), thereby producing magnetic fields that act on the permanent magnets (12 and 13).

L'invention concerne un lecteur optique (1) qui comprend : une partie mobile principale (10); une paire de tiges de torsion principales (21 et 22) qui sont disposées à l'opposé l'une de l'autre sur les deux extrémités de la partie mobile principale (10), qui soutiennent la partie mobile principale (10) en lui permettant de pivoter, et qui peuvent être déformées par torsion; et une unité d'entraînement principale (30) qui fait pivoter la partie mobile principale (10). La partie mobile principale (10) comprend : une partie de miroir (11) pourvue d'une surface réfléchissante (11a) qui réfléchit la lumière; et une paire d'aimants permanents (12 et 13) disposés à l'opposé l'un de l'autre et séparés par la partie de miroir (11), chacun d'eux s'étendant le long de l'axe de pivotement (X-X) de la partie mobile principale (10). L'unité d'entraînement principale (30) comprend : des parties de culasse (31, 32, 33) disposées de manière à entourer les aimants permanents (12 et 13) le long de l'axe de pivotement (X-X) de la partie mobile principale (10); et des bobines (34) qui sont enroulées autour des parties de culasse (31, 32, 33) et qui, une fois alimentées, excitent les parties de culasse (31, 32, 33) pour générer des champs magnétiques qui agissent sur les aimants permanents (12 et 13).
