    摘要: An ocular optical system suitable for a head- or face-mounted image display apparatus which is compact, lightweight and satisfactorily corrected for aberrations, and in which no intermediate image is formed. The image display apparatus includes an image display unit (9) and an optical system (10) for projecting a displayed image into an eyeball (7). The optical system (10) is arranged such that light rays which are emitted from the image display unit (9) and enter the eyeball (7) are reflected at least three times by surfaces (12, 13 and 14) having power in backward ray tracing.

    摘要: A photographic film cassette has a slit formed in a core of the spool. An engaging member having a spring force is disposed within the slit. The engaging member engages with an engagement hole formed in the trailer of a photographic film, so as to prevent the film trailer from being removed from the spool. In pulling the entirety of an exposed film out of the cassette so as to develop it, the engaging member is moved to an engaging release position to disengage it from the engagement hole.

    摘要: A photographic film cassette has a spool, rotation of which causes a film leader to advance outside of a cassette shell. In a receiving recess formed on a spool end for receiving a rewinding shaft of a camera, a pentagonal circumference is formed for receiving a driving force from the rewinding shaft. Inclined planes are formed on the inside of the receiving recess for guiding insertion of the rewinding shaft into the receiving recess. Because the spool is rotated in axial coincidence with the rewinding shaft, the film can be advanced reliably outside of the cassette by slipping the outermost turn of the wound film smoothly with reference to a self-advancing mechanism. In a preferred embodiment, a film cassette is constituted by two shell halves, with one of which a part of the film passage mouth is integrated. A positioning member is integrated with the same shell half for positioning the cassette shell in contact with a receiving member formed in a film loading chamber. The film passage mouth thus can be connected precisely to the film passageway in the camera.
