摘要： A resin lens includes an optical functional section that has an optical function, and a flange section that is formed around the optical functional section. A reference face is used as reference during positioning and fixing, and is formed on one face of the flange section. The face on which the reference face is formed is molded by an insert that mainly forms the optical functional section and a holder that mainly forms the flange section, during molding. The reference face of the flange section and an optical functional face that is the face of the optical functional section facing the reference face are molded by the insert, and a face of the flange section that is closer to the outer periphery than the reference face of the flange section is molded by the holder.

摘要： A case for flat objects (e.g., shells containing disc-shaped recording media) includes a pair of case walls, a bottom wall and opposed side walls attached to the case walls. The opposed side walls maintain the case walls in parallel separated relationship and establish an open end of the case opposite to the bottom wall. The side walls are provided with respective L-shaped cut-out regions having edges which establish respective resilient tabs. One end of each tab is connected to a respective one of the side walls while the opposite terminal end of each tab is unconnected to the side wall. The resilient tabs each include a notch formed in their end which is connected to the side wall. The notch thereby establishes a hinge region to allow the resilient tabs to be deflected inwardly of the case and thereby be in resilient contact with a lateral edge of a flat object within the case. The notch causes the resilient tab to be extended lengthwise so that the unconnected terminal end thereof is partially overlapped with a respective edge of the cut-out region. In such a manner, the unconnected terminal ends of the tabs are maintained inwardly of their respective side wall. Due to the resiliency of the tabs and the terminal end being overlapped with its respective cut-out edge, the lateral surfaces of a flat object are held thereby so as to prevent its needless escape
摘要翻译：用于平坦物体（例如，包含盘形记录介质的壳体）的壳体包括一对壳体壁，底壁和附接到壳体壁的相对侧壁。相对的侧壁将壳体壁保持平行分离的关系，并建立与底壁相对的壳体的开口端。侧壁设置有各自的L形切口区域，其具有建立相应的弹性突片的边缘。每个翼片的一端连接到相应的一个侧壁，而每个翼片的相对的末端未与侧壁连接。弹性片各自包括在其端部上形成的凹口，其连接到侧壁。因此，切口形成铰链区域，以允许弹性翼片向壳体向内偏转，从而与壳体内的平坦物体的侧边缘弹性接触。凹口使得弹性片长度方向延伸，使得其未连接的末端部分与切出区域的相应边缘重叠。以这种方式，突片的未连接的末端保持在它们各自的侧壁的内部。由于突片的弹性和终端与其相应的切口边缘重叠，平面物体的侧表面被保持，从而防止其不必要的逃逸
