    摘要: A photographic film cassette assembling method includes the steps of joining shell halves together by ultrasonic welding, to form a cassette shell, while accommodating a spool in the cassette shell. A film connection sheet is secured to the spool before the spool is mounted in the cassette shell. A free end of the film connection sheet is placed outside the cassette shell through a film passage mouth of the cassette shell. A strip of a photographic film is connected to the spool by attaching a trailing end of the photographic film to the free end of the film connection sheet and wound about the spool by rotating the spool. The photographic film may be directly secured to a spool having an engaging member formed therein and a film guide member formed integrally therewith. A free end or free ends of the guide member protrude slightly from the film passage mouth to the outside of the cassette shell. The trailing end of the photographic film is guided along the film guide member into the cassette shell toward the engaging member of the spool, thereby to bring the end of the photographic film into engagement with the engaging member.

    摘要: A plurality of shapes each having a fundamental construction of a flange are vacuum formed on a continuous sheet of thermoplastic resin. When blanking each of the formed shapes out of the resin sheet into an individual flange, a spool core is placed coaxially with the formed shape placed in the blanking position. The flange just blanked out of the resin sheet is moved in the blanking direction toward the spool core, to be fit on the spool core. The shapes are formed in a double line along the resin sheet, and thereafter, the resin sheet is slit along the longitudinal direction into two sheet branches each having the formed shapes arranged in a single line. The back side surfaces of the two sheet branches are opposed to each other, and the spool core is disposed between the sheet branches and oriented in a direction perpendicular to the back side surfaces of the sheet branches. The formed shapes are blanked out of the sheet branches in opposite directions toward opposite ends of the spool core.

    摘要: An internal focusing telephoto lens includes, in succession from the object side, a first lens unit of positive refractive power having at least a positive first lens component, a second lens unit having negative refractive power and movable along the optical axis for focusing, and a third lens unit having positive refractive power and having an imaging function. The first lens unit forms a substantially afocal system with the second lens unit, and is designed to satisfy the following conditions:0.43
