Patent number: 6766108Abstract: A lens-fitted photo film unit of a waterproof type comprises a unit body covered with a case body and a lid member. A front window and a top window of the case body are made of transparent plastic. The lid member is also made of the transparent plastic. Methacrylate styrene resin is utilized as the transparent plastic, which is used for a taking lens, a viewfinder lens, and an underwater case constituted of the case body and the lid member. This transparent plastic is hardly clouded even if cosmetics of suntan lotion and so forth adhere thereto. Moreover, a poisonous gas causing photographic-film fog is prevented from rising so that photographic properties are not damaged.Type: GrantFiled: June 11, 2002Date of Patent: July 20, 2004Assignee: Fuji Photo Film Co., Ltd.Inventor: Keiji Uchiyama

Patent number: 6766109Abstract: A camera casing of the present invention is an integral two-color molded product whose case main body (32) consists of a transparent rigid resin layer (32a) and an opaque rigid resin layer (32b). Essential parts of the camera are exposed through the transparent resin layer (32a), so the camera may be operated from outside the casing. The casing is collected and melted as a whole without discriminating between the transparent rigid resin and the opaque rigid resin, to be recycled as a material for the opaque resin layer (32b) when the case main body is newly formed by two-color injection molding.Type: GrantFiled: March 13, 2003Date of Patent: July 20, 2004Assignee: Fuji Photo Film Co., Ltd.Inventors: Kenji Negishi, Keiji Uchiyama, Mitsuro Kamata, Toshio Sata

Patent number: 6516145Abstract: A waterproof camera includes a camera body having an actuation member that actuates an internal mechanism when pressed. A waterproof case is arranged to contain the camera body in a watertight fashion, with an opening arranged to face the actuation member and a stepped portion around the opening on an inside wall of the waterproof case. A resilient operation member having a button portion exposed to the outside through the opening has a mounting portion which fits on the stepped portion around the opening. The operation member can be resiliently deformed to press the actuation member when the button portion is depressed. A supporting member pushes the mounting portion against the stepped portion from inside the waterproof case, so as to secure the operation member. In one embodiment, the supporting member is fixed on the camera body.Type: GrantFiled: March 12, 2002Date of Patent: February 4, 2003Assignee: Fuji Photo Film Co., Ltd.Inventor: Keiji Uchiyama

Patent number: 6483991Abstract: A tablet shaped catalyst is disposed on an upper portion inside a waterproof housing. The catalyst, which is comprised of palladium, accelerates a chemical reaction for combining hydrogen gas and oxygen gas. The catalyst begins accelerating the chemical reaction just after contacting with hydrogen gas. By disposing said catalyst on an upper position inside the waterproof housing, hydrogen gas, lighter than the air, is effectively removed. This chemical reaction causes to generate water, so it is preferable to provide a water absorbent by the catalyst.Type: GrantFiled: January 29, 2001Date of Patent: November 19, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Keiji Uchiyama, Kenji Negishi, Yukito Suzuki

Patent number: 6404990Abstract: In a flash circuit of a flash device, a Zener diode (37) is connected to a tap point (23f) located at an intermediate position of a secondary coil of an oscillation transformer (23). The oscillation transformer (23) and an oscillation transistor (22) constitutes an oscillation circuit. A potential at the tap point (23f) changes proportionally to a voltage charged in a main capacitor (41). When the main capacitor (41) is charged up to a set voltage, the Zener diode (37) conducts a Zener current, which activates a stopping transistor (38) and thus deactivates the oscillation circuit. When a flash charge switch (51) is turned on, an end of a light guide portion of a charge condition indicator (60) protrudes out of a lens-fitted film unit. When the main capacitor (41) is charged up to the set voltage, a light emission element starts lighting and the light from the light emission element is projected from the end of the light guide portion.Type: GrantFiled: September 7, 2001Date of Patent: June 11, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Makoto Isozaki, Junichi Takagi, Kazumi Koike, Mitsuhiro Moriya, Keiji Uchiyama, Yukitsugu Hata
