摘要： The present invention relates generally to microfiche types of microfilm strip holders and more particularly to microfilm strip holders adapted for use in a fanning type magnetic file tray system. An embodiment of the invention illustrated in the drawings comprises front and rear rectangular panels of transparent and flexible synthetic plastic material, commonly referred to as a microfiche master, which provides a plurality of horizontal pockets for receiving microfilm strips. At least one of these pockets has mounted therein a magnetic strip, the opposite extremities of which terminate adjacent the vertical edge portions of the microfiche master or holder in position for cooperation with the magnets of a filing tray, to effect fanning apart of the upper margins of a predetermined group of holders.
摘要翻译：本发明总体上涉及缩微胶片类型的微缩胶片保持器，更具体地说，涉及适用于扇形型磁文件托盘系统的微缩胶带保持架。附图中所示的本发明的实施例包括通常称为缩微胶片母版的透明和柔性合成塑料材料的前后矩形板，其提供用于接收微缩胶带的多个水平袋。这些口袋中的至少一个已经在其中安装有磁条，其相对的末端终止于缩微胶片主体或保持器的垂直边缘部分的适当位置，以与文件托盘的磁体配合，以实现上边缘的间隔的预定组的持有人。

摘要： The present invention relates generally to improvements in filing tray structures, and more particularly to a novel tray device adapted for use in a fanning magnetic filing system. One embodiment of the invention as disclosed herein includes a tray structure wherein the bottom and sidewall sections are integral as well as non-magnetic. Endwall sections are interlockingly secured in a novel manner to the front and rear extremities of said sidewalls. An auxiliary index card or data sheet accommodating tray section having opposed upwardly flaring wall portions is located within the tray device. These flaring wall portions limit the extent to which the index cards or sheets may be tilted toward the front and rear of the tray device. The index cards have magnetic portions which cooperate with elongate magnets associated with the upright sidewall sections to effect fanning of the cards or data sheets.
摘要翻译：本发明一般涉及托盘结构的改进，更具体地涉及一种适用于扇形磁性归档系统的新型托盘装置。本文公开的本发明的一个实施例包括托盘结构，其中底部和侧壁部分是一体的以及非磁性的。端壁部分以新颖的方式互锁地固定到所述侧壁的前端和后端。具有相对的向上扩张的壁部分的辅助索引卡或数据表容纳托盘部分位于托盘装置内。这些扩口壁部分限制了索引卡片或纸张可能朝向托盘装置的前后方向倾斜的程度。索引卡具有磁性部分，其与与直立侧壁部分相关联的细长磁体配合，以实现卡或数据表的扇形化。
