    • Mutually non-mixable light-transmitting insulative liquid and conductive liquid having different refractive indices are accommodated in a light-transmitting liquid container forming a lens unit. The lens unit includes a first electrode which is in contact with the conductive liquid, one or more second electrodes which are insulated from the conductive liquid, and a correcting section which controls voltage to be applied between the first electrode and at least one of the second electrodes in accordance with a gravity direction, thereby changing a shape of an interface between the insulative liquid and the conductive liquid to correct distortion of the interface caused by the gravity.

    • A film carrier support mechanism for a film projector of the type having an upper cylindrical member for accommodating a light source, and a lower cylindrical member for accommodating an optical arrangement for projection. The light source is adapted to project a picture stored in any of multiple frames of a film. A support member is interposed between the upper and lower bodies for supporting a film carrier, which receives therein a film to be projected, such that the film carrier is movable in a two-dimensional direction in a plane which is perpendicular to the optical axis of the optical arrangement. The support member includes guide elements which cooperate with the film carrier to guide the film carrier in a lengthwise direction of the film, while the film carrier is in a predetermined position with respect to a direction perpendicular to a lengthwise direction thereof.

    • In a disk film projector, desired one of frames of image recorded on a rotary disk of film having a central engaging core is placed at a projecting position for selective reproduction of images recorded in the frames. There is provided a drive unit including a rotary driving shaft having its forward end engageable with the engaging core of the disk film. The rotary disk is held in a plane substantially normal to the rotary driving shaft upon insertion of the rotary disk in position within the projector. The disk film is introduced into, and taken out of, the projector only in a direction substantially normal to the rotary driving shaft. The driving shaft is normally urged in a direction such that the driving shaft is brought into engagement with the engaging core of the rotary disk held in the aforementioned manner. The rotary driving member is locked at a position spaced from the rotary disk when the rotary driving shaft is manually shifted against the urging member and away from the rotary disk.
    • 在盘片投影仪中,将记录在具有中心接合芯的胶片的旋转盘上的所需的图像帧放置在用于选择性再现记录在帧中的图像的突出位置。 提供了一种驱动单元,其包括旋转驱动轴,其旋转驱动轴的前端可与盘片的接合芯接合。 旋转盘在将旋转盘插入投影仪内的适当位置时,保持在基本上垂直于旋转驱动轴的平面中。 仅在基本上垂直于旋转驱动轴的方向上将光盘膜引入投影仪中并从其中取出。 驱动轴通常沿使得驱动轴与以上述方式保持的旋转盘的接合芯相接合的方向被推动。 当旋转驱动轴被手动地移动到推动构件并远离旋转盘时,旋转驱动构件被锁定在与旋转盘间隔开的位置处。
