Abstract
A microfiche punch unit and method are disclosed. The method and apparatus assure proper alignment between the images and the binary identification tabs attached to the edge of the microfiche. In the pre-tabbing stage the microfiche is punched to create reference holes which are measured from the image grids rather than the edge of the fiche. The microfiche is 'registered' (checked for alignment) by aligning the images with reference lines on the punch unit prior to punching the reference holes. During the actual tabbing, the fiche is placed over pegs added to a prior art tabbing press, to secure the fiche. The method and apparatus are ideally used in a microfiche storage/retrieval unit, such as those which are part of a digital imaging process.
