The readability of a paper document is often due to the “easy to handle” of the paper. In this paper, we analyze the action in ten kinds of readings on paper documents that occur in business (such as paper moving, page-turning). As a result, it was confirmed that various actions were performed at various frequencies for each reading. Moreover, in order to examine the reading support method from the viewpoint of the reading actions performed, we used cluster analysis of ten kinds of readings and obtained five clusters. Considering the support method for each of these clusters, the refreshed speed of the screen must be necessary for reading that frequently flips pages or moves between pages. Moreover, the lightness and thinness of reading devices must be remarkable for reading to move documents or to compare multiple documents. From our suggestions, it was clarified that the appropriate reading devices depend on the types of reading and that the supported functions depend on the types of reading.
