    • A photographic film cassette has photographic film wound on a spool and contained in a cassette shell. Rotation of the spool in the unwinding direction causes a leader to advance through a passageway and exit from a passage mouth. The passageway is defined by a pair of opposed inside faces. The first inside face confronts the emulsion surface of the photographic film, and the second inside face confronts its back surface. A separator claw is formed adjacent to the first inside face, and separates the leader from the roll. The separator claw is formed to project only to a small degree so that the photographic film is prevented from being rubbed and scratched thereby, even when the diameter of the roll is minimized. In a preferred embodiment, a camera for use with such a leader-advancing cassette has a receiving port, which is open to the inside of a cassette receiving chamber, and receives the photographic film as exited from the cassette. A front wall of the receiving port is formed so as to prevent the photographic film from being rubbed and scratched by the first inside face of the cassette.
    • 摄影胶片盒具有缠绕在卷轴上的照相胶卷并且容纳在盒壳中。 卷轴在展开方向的旋转使领导者前进通过通道并从通道口离开。 通道由一对相对的内表面限定。 第一内表面面对照相胶片的乳剂表面,第二内表面面对其背面。 与第一内侧相邻地形成分离爪,并将引导件与辊分离。 分离爪形成为只能稍微突出,从而即使当辊的直径最小化时,防止摄影胶片被擦拭和刮擦。 在优选实施例中,与这种前导前进盒一起使用的相机具有对盒接收室的内部开放的接收端口,并且接收从盒中退出的照相胶卷。 形成接收端口的前壁,以防止照相胶片被盒的第一内表面摩擦和划伤。

    • A photographic film cassette where rotation of a spool causes a film leader to advance to an exterior of a cassette shell from a film chamber through a film passageway. A pair of flanges are provided on both ends of the spool. Round ridges formed on inside surfaces of the flanges are in contact with edges of an outermost convolution of a roll of film. The roll of film is thereby prevented from loosening. A plurality of radially extending slits formed on the flanges in a radial manner divides the flanges into sections. The resistance of the flanges is reduced when the flanges are spread for releasing the film leader by spreaders. In another preferred embodiment, a plurality of holes or openings is formed on the flanges in order to reduce the resistance of the flanges against a spreading force for releasing the film leader.
    • 一种照相胶片盒,其中卷轴的旋转使得胶片引导者通过胶片通道从胶片室前进到盒壳的外部。 在阀芯的两端设有一对凸缘。 形成在凸缘的内表面上的圆形脊与一卷薄膜的最外圈的边缘接触。 由此可以防止胶卷的松动。 以径向方式形成在凸缘上的多个径向延伸的狭缝将凸缘分成多个部分。 当法兰被扩散以通过吊具释放胶片引导件时,法兰的阻力减小。 在另一个优选实施例中,在凸缘上形成多个孔或开口,以便减少凸缘抵抗用于释放胶卷头的扩展力的阻力。

    • A spectacles-type image display device having an image output unit that includes a display element that displays images and is disposed on a spectacle frame and a reflection unit that is disposed adjacent to at least one of spectacle lenses and reflects the image light that is output from the image output unit toward the eyeball so that the viewer can see a virtual image of the image is provided. The reflection unit is a reflection member having a positive refractive power and an effective luminous flux that is output from the image output unit and reaches the eyeball of the viewer is configured so that the width of the luminous flux perpendicular to an optical axis is minimum at the reflection unit with respect to the optical axis cross-section parallel to an incident surface of the optical axis relative to the reflection unit.
