Title (EN) FOCUS ADJUSTMENT UNIT AND IMAGE READING DEVICE
(FR) UNITÉ D'AJUSTEMENT DE FOYER ET DISPOSITIF DE LECTURE D'IMAGE
(JA) ピント調整ユニットおよび画像読取装置
Abstract:
(EN) A focus adjustment unit (63) comprises: a lens unit (202); two pins (205, 206); a support member (201); and a lens barrel (203). The lens unit (202) includes a lens (222). The two pins (205, 206) are secured to the lens unit (202). The support member (201) supports the two pins (205, 206) in such a manner that the lens unit (202) is movable. The lens barrel (203) rotates relative to the support member (201) to thus move the two pins (205, 206) relative to the support member (201) so that the lens (222) moves to adjust focus. At this time, a contact point (223) on the lens unit (202), which is different from the site to which the two pins (205, 206) are secured, comes in contact with the support member (201), and thus the lens unit (202) is supported on the support member (201).
(FR) Une unité de réglage de foyer (63) comprend : une unité de lentille (202); deux broches (205, 206); un élément de support (201); et un barillet d'objectif (203). L'unité de lentille (202) comprend une lentille (222). Les deux broches (205, 206) sont fixées à l'unité de lentille (202). L'élément de support (201) supporte les deux broches (205, 206) de telle sorte que l'unité de lentille (202) est mobile. Le barillet d'objectif (203) tourne par rapport à l'élément de support (201) pour déplacer ainsi les deux broches (205, 206) par rapport à l'élément de support (201) de telle sorte que la lentille (222) se déplace pour ajuster la mise au point. A ce moment, un point de contact (223) sur l'unité de lentille (202), qui est différent du site auquel les deux broches (205, 206) sont fixés, vient en contact avec l'élément de support (201), et ainsi l'unité de lentille (202) est supportée sur l'élément de support (201).
(JA) ピント調整ユニット(63)は、レンズユニット(202)と2つのピン(205~206)と支持部材(201)と鏡胴(203)とを備えている。レンズユニット(202)は、レンズ(222)を備えている。2つのピン(205~206)は、レンズユニット(202)に固定されている。支持部材(201)は、レンズユニット(202)が移動可能に2つのピン(205~206)を支持している。鏡胴(203)は、支持部材(201)に対して回転することにより、ピント調整のためにレンズ(222)が移動するように、支持部材(201)に対して2つのピン(205~206)を移動させる。このとき、レンズユニット(202)は、2つのピン(205~206)が固定されている部位と異なる接触点(223)が支持部材(201)に接触することにより、支持部材(201)に支持される。
