Abstract: front page image
(EN)The purpose of the present invention is to improve the hermeticity between a cover member and a transparent member of an optical scanning device and to improve dustproof performance thereof. The optical scanning device is provided with an elastic member (75) which is formed from a material different from that of a cover member (70) and molded on the cover member (70) so as to surround an opening (42) in order to provide a hermetic seal between the cover member (70) and a glass member (90). The elastic member (75) has a protruding part (75a) extending toward the glass member (90). The protruding part (75a) elastically deforms when abutting the glass member (90) so as to fill a gap between the cover member (70) and the glass member (90).
(FR)L'objectif de la présente invention est d'améliorer l'herméticité entre un élément couvercle et un élément transparent d'un dispositif de balayage optique et d'améliorer la performance de résistance à la poussière de celui-ci. Le dispositif de balayage optique est doté d'un élément élastique (75) qui est constitué d'un matériau différent de celui d'un élément couvercle (70) et moulé sur l'élément couvercle (70) de façon à entourer une ouverture (42) afin d'établir un joint hermétique entre l'élément couvercle (70) et un élément en verre (90). L'élément élastique (75) comporte une partie en saillie (75a) s'étendant vers l'élément en verre (90). La partie en saillie (75a) se déforme élastiquement lorsqu'elle est en butée contre l'élément en verre (90) de façon à remplir un interstice entre l'élément couvercle (70) et l'élément en verre (90).
(JA)光走査装置のカバー部材と透明部材の間の密閉性を向上させて、防塵性能を向上させること。 カバー部材70とガラス部材90との間を密閉するために、開口部42を囲うようにカバー部材70に成型された、カバー部材70と異なる材質の弾性部材75を備え、弾性部材75は、ガラス部材90に向かって伸びる突起部75aを有し、突起部75aは、ガラス部材90に当接して弾性変形することによってカバー部材70とガラス部材90と間の隙間を塞ぐ。
