Abstract: A disc cartridge is constructed so that disc access to a recording medium enclosed within the disc cartridge via an opening in the cartridge case is restricted by a disc tray and a shutter member disposed inside the cartridge case. The shutter member is rotatably attached to one of the disc tray and the cartridge case, and detachment of the shutter member is restricted at least in a range of rotation of the shutter member between a position where the shutter member covers part of the opening and a position where the shutter member has been withdrawn from the opening. Attachment of the shutter member is carried out without crimping.

Abstract: A disc cartridge which is capable of positively closing a disc access opening by shutter members. In the disc cartridge, a lower shell is formed with urging protuberances for urging shutter members in a manner causing the shutter members to pivotally move toward respective closing positions, and the shutter members are each formed with a protruding portion protruded from a side end face thereof such that a force for pressing the protruding portion against the urging protuberance is progressively increased after the protruding portion is brought into abutment with the urging protuberance before completion of a pivotal motion of a disc tray until the completion of the pivotal motion of the disc tray.

Abstract: The method of sucking water is capable of easily removing excess water included in a backing member adhered on a plate of a polishing apparatus. In the method, the excess water is removed from the backing member by the steps of: pressing a water absorbing member onto a holding surface of the backing member, on which the work piece is adhered and held, so as to absorb the excess water from the backing member; and sucking the excess water absorbed by the water absorbing member.

Abstract: A disc-shaped recording medium is housed inside a cartridge body including a lower shell and an upper shell formed so as to be capable of being fitted together. An opening for disc access, which is capable of exposing a region that extends from one outer edge part to another outer edge part on an opposite side of a center hole of the disc-shaped recording medium housed inside the cartridge body, is formed in the lower shell. A reinforcing member formed separately from the upper shell is fixed to an inner surface of the upper shell so as to cross the opening in the lower shell in a state where the lower shell is fitted to the upper shell.

Abstract: A disc cartridge comprises: a cartridge body including an upper shell and a lower shell at least one of which is provided with an opening for allowing disc access; a disc tray that is formed to allow a disc-like recording medium to be placed thereon and is arranged in the cartridge body to be rotatable; a pair of shutter members each including a shaft-receiving hole to which a supporting shaft formed in the disc tray is to be inserted, an annular surrounding portion that surrounds the shaft-receiving hole, and a blade portion formed integrally with the surrounding portion outside the surrounding portion, the pair of shutter members being supported by the disc tray to be rotatable and being capable of opening and closing the opening of the cartridge body, each of a pair of shutter members is a member formed by injection molding and has a plurality of gate marks caused by injection molding, one of the gate marks is formed in a surrounding portion of the shutter member and another one of the gate marks is formed
