Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case for an integrated information recording medium in which an optical sensor and a liquid crystal recording medium are laminated and an image is recorded by changing the orientation of the liquid crystal recording medium.

[0002]

2. Description of the Related Art Conventionally, in a liquid crystal recording medium in which a liquid crystal recording medium having a liquid crystal-polymer composite layer formed on an electrode and an optical sensor having a photoconductive layer formed on the electrode layer are laminated and integrated. It is known that an image is recorded by voltage application exposure. FIG. 1 shows such an integrated information recording medium. In the figure, 10 is an optical sensor and 20 is a liquid crystal recording medium. In the optical sensor 10, a transparent electrode 12 and a photoconductive layer 13 are sequentially laminated on a transparent support 11, and a liquid crystal recording medium 20 has a liquid crystal-polymer composite layer 23 on a transparent electrode 22.
Are laminated. The photoconductive layer 13 has a single-layer structure in which trinitrofluorenone is added to polyvinyl carbazole as an organic photoconductive layer, or an azo pigment as a charge generation layer. And the like, and a layer obtained by laminating a material in which a hydrazone derivative is mixed with a resin such as polycarbonate as a charge transfer layer can be used. In the case of the integrated information recording medium, FIG.
As shown in FIG. 1 (a), a liquid crystal recording medium is directly laminated on an optical sensor, as shown in FIG. 1 (b), as shown in FIG. There is a reflection type in which a layer is a dielectric mirror.

As shown in FIG. 2, when a voltage is applied between the electrodes 12 and 22 of such an integral type information recording medium by a power source 30 and visible light is irradiated as writing light, the photoconductive layer is generated according to the exposure intensity. The conductivity of 13 changes, the electric field applied to the liquid crystal-polymer composite layer 23 changes, and the alignment state of the liquid crystal changes, which state is maintained even after the applied voltage is turned off and the electric field is removed. Information is recorded.

[0004]

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, it is necessary to handle a very thin medium with care, and even if the glass is broken by a slight impact, or if it is directly touched with the hand, the image quality is affected. Further, since the medium is thin and small, it is difficult to reliably take out the electrodes, and it is not possible to cope with the case where the medium is loaded in a camera or the like to enable easy photographing.

The present invention has been made in view of the above circumstances, and provides a storage case for an integrated information recording medium which can protect the integrated medium and can reliably and easily take out electrodes from the medium. With the goal.

[0006]

According to the present invention, a window corresponding to an image region, an electrode pressing rubber pad, an upper lid having a transmittance monitor window, and a lower lid having an exposure window are integrated. It is characterized in that the information recording medium is housed and fixed to each other, and an electrode take-out port is formed in the front part.
With this configuration, the recording medium is protected, and the electrodes can be taken out reliably and easily.

Is forming. The transmittance monitor area 33 is an extraction electrode area connected to each of the R, G, and B electrodes, and is for monitoring the transmittance of a dark portion. Further, a current value monitor area 34 is formed at the end of the medium and forms an area for monitoring the current (dark current) in the dark portion.

As shown in the sectional view of (c), a through hole is formed in a substrate made of a polyimide film having a thickness of 25 μm, an electrode material is poured into this hole, and wiring is patterned on the back surface side. By making contact with the upper electrode of the medium with the bump head 42 and printing the wiring on the back surface side with respect to the contact portion, electric discharge between the medium and the medium is prevented. As shown in the enlarged view of FIG. 5D, the bump head 42 is formed by depositing Au on the surface of an alloy of Ni, Cu, and Ag, and has a height of several μm to several tens μm.
