摘要： Device for projecting transparencies which bear sections of magnetic tapes having recorded thereon binary digital words representative of alphanumerical characters. During projection, the binary words are converted into visual characters by a ''''digital-image'''' converter. The device can sort transparencies by comparing the digital words recorded thereon to given sorting words. The rate of the electronic part of the device is synchronized with the velocity of the movement of the transparencies when they travel from their feed position to their projection position.
摘要翻译：用于投影透明胶片的装置，其承载记录有代表字母数字字符的二进制数字字的磁带部分。在投影期间，二进制字通过“数字图像”转换器转换为视觉字符。设备可以通过将记录在其上的数字词与给定的排序词进行比较来对透明胶片进行分类。当装置的电子部件从其进给位置行进到其投影位置时，该装置的电子部件的速率与透明胶片的移动速度同步。
