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 lens is manufactured by hardening soft material filled inside a molding tool by cooling. The lens includes a convex lens portion having an optical axis, and a marking portion located outside of an effective diameter of the lens portion. The shape or the position of the marking portion is set to prevent deformation of the marking portion by contact with the molding tool due to shrinkage of the material during cooling.

摘要： Scratches on the recording disk caused by sliding of a disk cartridge shutter is prevented by slidably inserting first and second shutters between a tray and a case on the opposite side to a recording disk accommodating portion of the tray. The first shutter simultaneously opens and closes a case side driving shaft insert hole, a case side head insert hole, a tray side driving shaft insert hole, and a tray side head insert hole. The second shutter opens and closes a terminal hole. The second shutter is opened independently of the first shutter and is held in a position so that the case side driving shaft insert hole, the case side head insert hole, the tray side driving shaft insert hole, and the tray side head insert hole are not closed. Closing the first shutter, however, causes the second shutter to also close.
摘要翻译：通过将第一和第二快门可滑动地插入托盘和与托盘的记录盘容纳部分相反的一侧的壳体之间来防止由盘盒快门的滑动引起的记录盘上的划痕。第一快门同时打开和关闭壳体侧驱动轴插入孔，壳体侧头插入孔，托盘侧驱动轴插入孔和托盘侧头插入孔。第二个挡板打开和关闭端子孔。第二挡板独立于第一挡板打开，并且被保持在使得壳体侧驱动轴插入孔，壳体侧头插入孔，托盘侧驱动轴插入孔和托盘侧头插入孔不是关闭。然而，关闭第一个快门会导致第二个快门也关闭。
