Hand-held information equipment provided integrally with an image reader reads out image data of a data storage unit by means of a retrieval data creation requesting unit and sends them to an information processor. The information processor converts the image data into text data for retrieval by means of a character recognition unit and creates indexes by means of an index creation unit. On receipt of thus created text data and indexes, the hand-held information equipment combines the text data and indexes with the image data for entry into a data storage unit by means of a retrieval data entry unit.
