Abstract: A rechargeable battery includes a battery case, a cover that closes an open end of the battery case, and a power collection terminal arranged on the cover to supply power from a power generating element to an external terminal. The power collection terminal extends through a gasket arranged on a lower surface of the cover, an insulator arranged on an upper surface of the cover, and the external terminal arranged on an upper surface of the insulator. An annular sealing member is held between the lower surface of the cover and the gasket. The insulator is a resin-molded component. The insulator includes a through hole defined by an inner wall that includes a lower open end, an upper open end, and a central portion. At least one of the lower open end and the upper open end has a larger diameter than the central portion.

Abstract: A battery includes an external terminal member and an insulating member on an outer surface of a lid member so that an interval between the insulating member and the lid member is smaller in a long side of the lid member than in a short side. A weld mark is formed over the entire circumference of the lid member to extend across the outer surface of the lid member and an open end face of the case body. The weld mark not only extends across the outer surface of the lid member and the open end face of the case body but also reaches an outer side surface of the case body in a zone of the long side of the lid member facing the insulating member, but does not reach the outer side surface of the case body in a zone except the former zone.

Abstract: A cartridge includes a case member (500) and a shutter member (100). The case member (500) includes a upper case section (505) and a lowercase section (506). A step portion (507) is formed at a boundary (508) between the upper case section (505) and the lower case section (506). The upper case section (505) includes a shutter pressing section (517) including a plurality of eaves sections (510). Each of the plurality of eaves sections (510) is configured to engage with the eaves engagement section (104) of the shutter member (100). At least two of the plurality of eaves sections (510) are located spaced apart from each other by a predetermined distance (519). The lower case section (505) includes a connection portion (520). The connection portion (520) is connected to the step portion (507) at a location between the at least two eaves sections (510), which are located spaced apart from each other by the predetermined distance (519), of the plurality of eaves sections (510).

Abstract: The shutter member (1) is a shutter member used in a cartridge having a case member. The case member includes a medium storage section for storing an information medium having an information layer and a window section configured to allow at least a head to be inserted. The head is used to perform a recording operation or a reproduction operation for the information layer. The shutter member (1) includes a base member (2) operable to slide along a sidewall of the case member and a plate member (3) engaged with the base member (2). The plate member (3) is operable to open/close the window section of the case member in accordance with a sliding motion of the base member (2). The base member (2) and the plate member (3) are engaged with each other such that the plate member (3) can be removed from the base member (2).
