Title (EN) OPTICAL SCANNING DEVICE AND IMAGE FORMING DEVICE PROVIDED WITH OPTICAL SCANNING DEVICE
(FR) DISPOSITIF DE BALAYAGE OPTIQUE ET DISPOSITIF DE FORMATION D’IMAGE POURVU DU DISPOSITIF DE BALAYAGE OPTIQUE
(JA) 光走査装置および光走査装置を備えた画像形成装置
Abstract: front page image
(EN) An optical scanning device provided with a housing, a plurality of light sources, a deflection scanning unit that performs deflection scanning of light beams from the plurality of light sources onto a plurality of bodies to be scanned, and a plurality of optical units disposed between the deflection scanning unit and the bodies to be scanned, the optical scanning device being characterized in that an optical unit supporting member for supporting the optical units is provided, the optical unit supporting member supports the plurality of optical units disposed at a prescribed interval, and a thermal expansion coefficient of the optical unit supporting member is smaller than a thermal expansion coefficient of the housing.
(FR) La présente invention concerne un dispositif de balayage optique pourvu d'un boîtier, d'une pluralité de sources de lumière, d'une unité de balayage de déviation qui effectue un balayage de déviation de faisceaux lumineux provenant de la pluralité de sources de lumière sur une pluralité de corps devant être balayés, et d'une pluralité d'unités optiques disposées entre l'unité de balayage de déviation et les corps devant être balayés, le dispositif de balayage optique étant caractérisé en ce qu'un élément de support d'unité optique pour soutenir les unités optiques est fourni, l'élément de support d'unité optique soutenant la pluralité d'unités optiques disposées à un intervalle prescrit, et un coefficient de dilatation thermique de l'élément de support d'unité optique est inférieur à un coefficient de dilatation thermique du boîtier.
(JA) 筐体と、複数の光源と、前記複数の光源からの光ビームを複数の被走査体に偏向走査する偏向走査部と、前記偏向走査部と前記被走査体との間に配設された複数の光学部とを備えた光走査装置において、前記光学部を支持する光学部支持部材を備え、前記光学部支持部材は、予め定められた間隔で配設された前記複数の光学部を支持し、前記光学部支持部材の熱膨張係数は、前記筐体の熱膨張係数よりも小さいことを特徴とする光走査装置。
