    • A display unit is provided which enables monocular observation of a magnified displayed image, and binocular observation of a non-magnified displayed image. The display unit comprises a liquid crystal display element having pixels arranged two-dimensionally, and a backlight source for illuminating the liquid crystal display element from the backside. The backlight source comprises a micro-spotlight illumination system constituted of a surface light source, a barrier element, and a microlenses. The barrier element is controlled to take a complete transmission mode to transmit the light emitted form the surface light source or an aperture-formation mode to form apertures in matrix arrangement. In the aperture formation mode, the microlenses are focused substantially on the apertures respectively. The apertures, the microlenses corresponding thereto, and the pixels corresponding thereto are arranged such that the optical axes of the respective micro-spotlight illumination system pass through the pixels of the corresponding liquid crystal display elements from the backside and come to intercross roughly at one point on a pupil of an eye E brought close to the display face of the liquid crystal display element at a short distance not focusable physiologically.

    • An integral frame type paper feeder in which perforated paper is fed by a pin-carrying feed belt set in a main frame by a driving sprocket. The paper feeder has a pair of sub-frames for assembling the feed belt and driving sprocket in a sub-assembly, and a main frame consisting of a pair of opposed side plates spaced from each other at a predetermined distance, and to which the sub-frames are fixed, and an upper plate the upper surface of which constitutes a paper feed surface. The upper plate has a feed belt moving bore which extends in the direction in which the perforated paper is fed, and which causes the portion of the feed belt on which the perforated paper is being fed to be aligned with the paper feed surface. The two sub-frames, and the feed belt and the driving sprocket are combined with the sub-frames into a driving assembly, and this is fitted between the side plates of the main frame.
    • 一种整体的框架型给纸机,其中穿孔纸被由驱动链轮设置在主框架中的销钉进给带进给。 供纸器具有一对子组件,用于在子组件中组装进给带和驱动链轮;以及主框架,由一对彼此隔开预定距离的相对的侧板组成,并且子组件 框架是固定的,并且其上表面构成供纸表面的上板。 上板具有沿着穿孔纸进给的方向延伸的进给带移动孔,并且使进给带上的穿孔纸被供给的部分与供纸表面对齐。 两个子框架以及馈送带和驱动链轮与子框架组合成驱动组件,并且它被安装在主框架的侧板之间。
