Abstract

A device main body is formed portable, which includes (i) an information writing/erasing section which erases information recorded in a liquid crystal paper and returns the liquid crystal paper into an initialized state in which information recording is possible, and records information previously stored in the device main body into the initialized liquid crystal paper as required, and (ii) a sheet holding section which holds the liquid crystal paper in such a manner that the liquid crystal paper can be transported to an information erasure position and an information recording position in the information writing/erasing section and that the liquid crystal paper is curved at portions thereof other than those at which information recording and erasing is carried out. With this, it is possible to provide an information recording device with improved operability, such as improved portability and capability of easily reading out information at any place.
