    • Provided is a curable resin composition which has excellent optical properties, heat resistance, transparency, low water absorbability, and mold release property in molding, and reduces the occurrence of a burr from a mold. Also provided are a cured product thereof and an optical material. The curable resin composition includes: a component (A): a soluble polyfunctional (meth)acrylic acid ester copolymer which is obtained by copolymerizing components including a monofunctional (meth)acrylic acid ester (a) having an alicyclic structure, a bifunctional (meth)acrylic acid ester (b), and 2,4-diphenyl-4-methyl-1-pentene (c), has a reactive (meth)acrylate group derived from (b) in a side chain and a structural unit derived from (c) at an end, has a Mw of 2,000 to 20,000, and is soluble in an organic solvent; a component (B): a polyfunctional (meth)acrylate; and a component (C): an initiator, in which the blending amounts (weight ratio) of the respective components are as follows: (B)/(A)=5 to 250/100, and (C)/[(B)+(A)]=0.1 to 10/100.
    • 提供一种在成型时具有优异的光学性能,耐热性,透明性,低吸水性和脱模性的固化性树脂组合物,并且减少了来自模具的毛刺的发生。 还提供了其固化产物和光学材料。 可固化树脂组合物包括:组分(A):可溶性多官能(甲基)丙烯酸酯共聚物,其通过使包含具有脂环结构的单官能(甲基)丙烯酸酯(a),双官能(甲基) 丙烯酸酯(b)和2,4-二苯基-4-甲基-1-戊烯(c)在侧链中具有衍生自(b)的反应性(甲基)丙烯酸酯基和衍生自(c )的Mw为2000〜20,000,可溶于有机溶剂; 组分(B):多官能(甲基)丙烯酸酯; (B)/(A)= 5〜250/100,(C)/ [(B))的组分(C):各成分的配合量(重量比) +(A)] = 0.1〜10/100。

    • An image forming apparatus includes a printhead, a carriage, one or more guide members, and a positioning mechanism. The printhead is mounted on the carriage. The one or more guide members support the carriage. The positioning mechanism includes an eccentric bearing and a rotation restrictor. The eccentric bearing is connected to each guide member and rotatable around a rotational axis offset from a guide member longitudinal axis to move the guide member relative to a substantially horizontal plane. The rotation restrictor defines a first point of contact with the eccentric bearing when the carriage is in a first operational position, and a second point of contact with the eccentric bearing when the carriage is in a second operational position. At least one of the first and second points of contact is displaceable with respect to the bearing rotational axis to modify the corresponding operational position of the carriage.
    • 图像形成装置包括打印头,滑架,一个或多个引导构件和定位机构。 打印头安装在滑架上。 一个或多个引导构件支撑托架。 定位机构包括偏心轴承和旋转限制器。 偏心轴承连接到每个引导构件并且可围绕与引导构件纵向轴线偏移的旋转轴线旋转,以相对于基本上水平的平面移动引导构件。 旋转限制器限定当滑架处于第一操作位置时与偏心轴承的第一接触点,以及当滑架处于第二操作位置时与偏心轴承的第二接触点。 所述第一和第二接触点中的至少一个相对于所述轴承旋转轴线是可移动的,以改变所述托架的对应的操作位置。
