Claim:
A sheet bundle with storage tags, comprising: a plurality of sheets stacked on one another, each sheet having a storage tag attached at an attachment position and having a thickness larger at the attachment position than other positions thereof, the plurality of sheets including a plurality of kinds of sheets which have different attachment positions when the sheet bundle is viewed from a direction orthogonal to a surface of the sheets, each of the sheets having four areas defined by dividing each of the sheets by a center in a short side direction and a center in a long side direction; wherein the plurality kinds of sheets are overlapped such that the attachment positions sequentially move between the four areas on a sheet-by-sheet basis, the attachment positions of every four sheets are provided in the four areas, respectively, the attachment positions are different from each other in each of the four areas such that in a stack of more than four sheets, the storage tags do not overlap in any direction orthogonal to a surface of the sheets, and a position of a gravity center of the storage tags for every four sheets is provided at the center of the sheets.
