    • The invention provides an apparatus for optically writing a data onto a non-exposed film being coated with photosensive material while moving the film to a predetermined direction. The data represents a film frame No., photosensitive emulsion lot No. and so on. The apparatus has two groups of LEDs being arranged with a pitch in parallel two lines being crossing at right angles to a film proceeding direction. The disposing position of LEDs on the one line differs by half of the pitch from that on another line. Therefore, the center of light spot on the one of spotted parallel line irradiated on the film does not face with that on another spotted line along the film proceeding direction. Further, the emission timings of the two groups of light emission sources are respectively controlled to have some time lag therebetween, thereby superposing partially the parallel two spotted lines.
    • 本发明提供了一种用于在将薄膜移动到预定方向的同时将数据光学地写入到涂有光敏材料的未曝光胶片上的装置。 数据表示胶片框号,感光乳胶批号等。 该装置具有两组LED,它们以平行的间距排列,两条线与成膜方向成直角相交。 在一条线上的LED的布置位置与另一条线上的距离的距离不同。 因此,照射在胶片上的点状平行线上的光点中心与胶片前进方向上的另一个点线不同。 此外,两组发光源的发射定时分别被控制为在它们之间具有一些时间差,从而部分地叠加平行的两个发光线。
