Abstract:
(EN) [Problem] To provide a drive unit, which is capable of driving forward/backward a movable section with respect to a fixed section using a voice coil motor, generates a pressing force with a simple structure, and has reduced dimensions and reduced weight, an optical unit, an image pickup apparatus, and an endoscope. [Solution] A drive unit (1) is characterized in being provided with: a cylindrical fixed section (2) having a predetermined axis (C) at the center; a cylindrical movable section (3), which is disposed inside of the fixed section (2), and which has the axis (C) at the center; a front frame section (4), which is attached to one end side of the fixed section (2), and which has at least a magnetic body; and a voice coil motor (10), which is capable of relatively moving the movable section (3) in the axis (C) direction with respect to the fixed section (2) by means of a coil (11) disposed on the fixed section (2), and a magnet (12) disposed on the movable section (3). The drive unit is also characterized in that the magnet (12) of the movable section (3) is pressed by means of the magnetic body.
(FR) [Problème] Fournir une unité d'entraînement, qui soit capable d'entraîner en avant/arrière une partie mobile par rapport à une partie fixe en utilisant un moteur à bobine mobile, qui génère une force de pression avec une structure simple, et qui ait des dimensions réduites et un poids réduit, ainsi qu'une unité optique, un appareil de capture d'images, et un endoscope. [Solution] Une unité d'entraînement (1) est caractérisée en ce qu'elle comprend : une partie fixe cylindrique (2) ayant un axe prédéterminé (C) au centre ; une partie mobile cylindrique (3), qui est disposée à l'intérieur de la partie fixe (2), et qui a l'axe (C) au centre ; une partie de cadre avant (4), qui est fixée à un côté d'extrémité de la partie fixe (2), et qui comporte au moins un corps magnétique ; et un moteur à bobine mobile (10), qui est capable de déplacer de manière relative la partie mobile (3) dans le sens de l'axe (C) par rapport à la partie fixe (2) au moyen d'une bobine (11) disposée sur la partie fixe (2), et d'un aimant (12) disposé sur la partie mobile (3). L'unité d'entraînement est également caractérisée en ce que l'aimant (12) de la partie mobile (3) est pressé au moyen du corps magnétique.
(JA) 【課題】 ボイスコイルモータを用いて固定部に対して可動部を進退駆動することができると共に、簡単な構造で付勢力を発生する小型化及び軽量化された駆動ユニット、光学ユニット、撮像装置及び内視鏡を提供する。 【解決手段】 駆動ユニット1は、所定の軸Cを中心とした筒形状の固定部2と、固定部2の内側に配置され軸Cを中心とした筒形状の可動部3と、固定部2の一端側に取り付けられ、少なくとも磁性体を有する前枠部4と、 固定部2に配置されたコイル11と、可動部3に配置された磁石12と、によって、可動部3を固定部2に対して、軸C方向に相対移動させることが可能なボイスコイルモータ10と、を備え、可動部3の磁石12は、磁性体によって付勢されることを特徴とする。
