By the way, the layer thicknesses of the liquid crystal recording medium and the optical sensor are about 6 μm and 10 μm, respectively, and the layer thickness of the entire integrated information recording medium is very thin, less than 20 μm. As described above, the electrode extraction of a very thin liquid crystal recording medium is conventionally performed by pressing an electrode contact with an elastic body, but it is difficult to extract the electrode reliably and easily because the medium is thin and small. For example, it is not possible to cope with the case where the camera is loaded in a camera or the like to enable easy photographing. Further, the number of parts for taking out the electrodes increases and the structure becomes complicated, which is a problem in mass production.
