Zusammenfassung: | To enable the pasting of a sheet member to a lens member without causing air bubble residue to occur due to the ingress of air.SOLUTION: Provided is an eyeglass lens manufacturing device 10 for pasting a sheet member S to one face of a lens member L, the eyeglass lens manufacturing device 10 being constituted by comprising: a chamber 11 having an opening 11a covered with the sheet member S on one side and a lens support 11b for supporting the lens member L on the other side that is arranged movably toward the opening 11a, for forming a sealed space 11d between the sheet member S covering the opening 11a and the lens member L supported by the lens support 11b; a pressure reducing mechanism 12 for depressurizing the sealed space 11d in the chamber 11; and a movement limiting mechanism 13 for limiting the movement of the lens support 11b during depressurizing by the pressure reducing mechanism 12.SELECTED DRAWING: Figure 2
【課題】空気の入り込みによる気泡残存が生じることなく、レンズ部材へのシート部材の貼着を可能にする。【解決手段】レンズ部材Lの一面にシート部材Sを貼り付ける眼鏡レンズ製造装置10であって、一方の側に前記シート部材Sで覆われる開口11aを有し、他方の側に前記レンズ部材Lを支持するレンズ支持体11bが前記開口11aに向けて移動可能に配され、前記開口11aを覆う前記シート部材Sと前記レンズ支持体11bに支持される前記レンズ部材Lとの間に密封空間11dを形成するチャンバ11と、前記チャンバ11における前記密封空間11dを減圧する減圧機構12と、前記減圧機構12による減圧中の前記レンズ支持体11bの移動を制限する移動制限機構13と、を備えて眼鏡レンズ製造装置10を構成する。【選択図】図2 |
