The present invention relates to a method, apparatus for recording and reproducing input information, and a recording medium such as a card or a label.

As a conventional high sensitivity photographing technique, the silver salt photographing method is known. In the silver salt photographing method, the photographed image is recorded on a film or the like through a developing process, and the image is reproduced by using a silver salt oil (photo paper, etc.) or by optically scanning the developing film and reproducing it on a cathode ray tube (hereinafter referred to as a CRT). .

Electrostatic and latent images are optically formed on the surface of the photoconductive layer by laminating the electrodes and the photoconductive layer, and totally charging the photoconductive layer on the photoconductive layer in a dark place and then exposing it to strong light to leak and remove the charges in the area. There is an electrophotographic technique in which a toner having a residual electrostatic charge and a reverse polarity charge (or a polar polarity charge) is attached and developed. However, it is generally used for copying because it cannot be used for photographing because of its low sensitivity, and the toner phenomenon usually occurs immediately after the formation of the electrostatic latent image because of the short holding time of the electrostatic charge.

In addition, with TV imaging technology, the image information obtained by the imaging tube is taken out as an electrical signal using an optical semiconductor and output to the CRT as it is, or video recording using magnetic recording or the like and image output on the CRT at any time. And the like.

The silver dye photographing method is excellent as a means of preserving the subject image, but the development process is required to form the silver dye image, and complex optical, electrical or chemical processing such as hard copy, soft copy (CRT output), etc. is required in image reproduction. .

The development of electrostatic latent image obtained by electrophotographic technique is simpler and faster than silver salt transfer method, but the preservation of latent image is very short and the resolution and image quality of developer are lower than silver salt photography method.

TV imaging techniques require serial sequential scanning to retrieve and record the electrical phase signal obtained by the imaging tube. Serial sequential scanning is carried out by an electron beam in the imaging tube and by a magnetic head in video recording. However, resolution is significantly lower than that of planar analog recording such as silver-colored photographs because resolution depends on the scanning player.

In addition, TV imaging systems using solid state imaging devices (CCD, etc.), which have recently been developed, are also essentially the same in terms of resolution.

Problems inherent in these technologies include a complicated processing process if image recording is high quality and high resolution, and a lack of memory function or poor image quality if the process is simple.

Records, cassette tapes, and the like are used for recording audio information, and video tapes, compact discs, optical discs, and the like are used for recording image information and audio information.

These records and cassette tapes are very convenient means for audio recording, but because of their low memory capacity, they cannot record image information, and recording on video tapes requires not only sequential scanning but also resolution of silver-colored photographs. Significantly lower than analog recording. The same holds true for compact discs, optical discs, and the like.

In the printing field, a scanner, which is conventionally composed of an original scanning unit, a computer, and an exposure recording unit, is a means for reading an original, performing proper image processing such as color correction or sharpening, and recording on a film.

The case of the color scanner is described as follows.

The document scanning unit photo-scans a given color document to obtain three color separation signals of uncorrected red (R), green (G), and blue (B), and records them on a magnetic disk or magnetic tape. The computer reads the recorded data and performs various processes such as color correction, state correction, and phase synthesis on the signals to produce a corrected four-color decomposition signal.

In the exposure recording section, scanning exposure is applied to the film at the same time as the scanning of the document by such a signal, so that the corrected four-color decomposition plane image can be output.

In the conventional scanner system, since image data from which an original is read is expanded, it is stored in a magnetic disk or a magnetic tape, and then read out.

Therefore, it takes a very long time to write and read a magnetic disk or a magnetic tape. In order to store a plurality of very large image data, for example, 10 MB in A4 size, a large number of magnetic disks or magnetic tapes and a space for the same are required. need. In addition, there is a problem that data stored in magnetic tape is destroyed during long-term storage.

In the case of printing, it is necessary to arrange the originals in a cylindrical reading cylinder, and if the originals are to be rotated at a predetermined angle, it is difficult to arrange the correct reading angles in the reading cylinder as well as color correction, Since masking, sharpening processing, and the like are performed by a computer operation, there is a problem that the computer is enlarged and the device is enormously large and the price is increased in order to perform a large arithmetic operation.

In recent years, in the printing process, generally, in the printing process, an enlargement ratio is specified for a slide-printed document received from a trading partner, and a trimming for cutting and engraving part of the original is performed in the planning section of the printing process.

For example, to specify the trimming, place the tracing paper on a document such as 35 mm, draw a thin drawing with a pencil and designate the trimming part, write down the magnification on the tracing paper, and put it in a plastic bag such as cellophane containing the printed document. It is attached to the process sheet and goes to the printing process.

As described above, in the conventional printing system, planning information such as the trimming position and enlargement ratio is written in the tracing paper in the planning part and sent to each process along with the printed document, so that the tracing paper is torn or soiled on the way. A defect is occurring.

In addition, in the conventional scanner, since the printed document itself is attached to the drum, there is a problem that the document is torn when the fingerprint of the person gets on or falls off.

In the case of changing the magnification, for example, in the case of a low magnification, the original is directly attached to the glass drum, but a newton ring is generated due to a partial difference in the degree of adhesion between the drum and the printed document. I put it. In addition, in the case of high magnification, since the powdery phase appears in printing when Nikkal powder is used, the printed document is immersed in paraffin and then wound in a transparent polyester film. In this case, there is a problem of dirtying the document in any case because it sprays Nikkal powder or immerses the print document in paraffin.

Moreover, in order to perform such a process, acquisition time takes a lot from the beginning, and work efficiency cannot be improved.

In the conventional copier, the electrode and the photoconductor are laminated, charged in front of the photoconductive layer on the photoconductive layer in a dark place, and then exposed to strong light to make the photoconductive layer at the site where the light reaches the conductive, The electrostatic latent image is optically formed on the surface of the photoconductive layer by leaking out, and a toner having the latent electrostatic charge and the reverse polarity charge (or the same polarity charge) is adhered to the developing method.

However, in the exposure method of the conventional copier, the electrostatic latent image is formed by corona charging the entire surface with a high voltage and then exposing it with a strong debt, so there is a problem that high voltage and high power are required. In addition, developing the resulting electrostatic latent image by developing the toner can be performed simply and quickly, but since the holding time of the electrostatic latent image is very short, the toner should be developed immediately after the formation of the electrostatic latent image and the toner developing at any time after the electrostatic latent image formation is impossible. It was.

1 is a view for explaining a recording method of the electrostatic image recording and reproducing method of the present invention, in which 1 is a photoconductor, 3 is an information holding medium, 5 is a photoconductive layer support, 7 is a photoconductor electrode, 9 is a photoconductive layer, and Silver insulating layer, 13 is an information holding medium electrode, 15 is an insulating layer support, and 17 is a power source.

Fig. 1 shows the exposure on the photoconductor 1 side. First, a transparent photoconductor electrode 7 of ITO of 1000 두께 thickness is formed on a photoconductive layer support 5 made of glass having a thickness of 1 mm. It consists of the photosensitive member 1 which provided the photoconductive layer 9 of about 10 micrometers. The information holding medium 3 is disposed with respect to the photosensitive member 1 with a gap of about 10 탆 interposed therebetween. The information holding medium 3 is formed by forming an insulating layer 11 having a thickness of 1000 Å on an insulating layer support 15 made of glass having a thickness of 1 mm.

First, as shown in FIG. 1 (a), the information holding medium 3 is arranged with respect to the photoconductor 1 with a gap of about 10 mu m interposed therebetween, and as shown in FIG. A voltage is applied between the two electrodes 7 and 13 by (17).

If it is in a dark place, since the photoconductive layer 9 is a high resistor, no change occurs between the electrodes. However, when light is incident on the photoconductor 1 side, the photoconductive layer 9 at the portion where the light is incident exhibits electrical conductivity and discharges between the insulating layer 11 to accumulate charge in the insulating layer 11.

When the exposure is completed, the formation of the electrostatic latent image is terminated by turning off the voltage as shown in FIG. 1 (c) and then taking out the information holding medium 3 as shown in FIG. 1 (d).

In addition, the photosensitive member 1 and the information holding medium 3 may be contactless instead of the above-described non-contact type. In the case of the contact type, positive or negative charge is injected into the exposed portion of the photoconductive layer 9 on the photoconductor electrode 7 side, and the charge is attracted to the electrode 13 on the information bearing medium 3 side to form the photoconductive layer 9. The charge transfer stops at the place where it reaches the surface of the insulating layer 11, and the injected charge is accumulated at the site. When the photosensitive member 1 and the information holding medium 3 are separated, the insulating layer 11 is separated in a state where charge is accumulated.

When the recording method is planar analog recording, high resolution can be obtained in the same way as the silver dye photographing method, and the surface charges formed on the insulating layer 11 are exposed to the air environment, but the air has good insulation performance, so it is not discharged regardless of bright or dark places. It is preserved for a long time without.

The charge preservation period on the insulating layer 11 is determined according to the property of the insulator and is influenced by the charge trapping characteristics of the insulator in addition to the insulation of air.

In the above description, the case where the charge is the surface charge is described. However, the injection charge may accumulate only on the surface, and microscopically penetrates inside the insulator surface and traps electrons or holes in the structure of the material. In long time will be preserved. The surface of the insulating layer 11 may be covered with an insulating film or the like in order to prevent physical damage to the information bearing medium or discharge generated when the humidity is high.

Hereinafter, the constituent materials of the photosensitive member and the information holding medium used in the invention will be described.

As the photoconductive layer support 5, the material and thickness thereof are not particularly limited as long as the photoconductive layer supporter has strength enough to support the photoconductor. For example, rigid bodies such as flexible plastic films, metal foils, paper, or glass, plastic sheets, and metal plates (which may also serve as electrodes) are used.

However, when used in a device for recording information by incorporating a debt from the photosensitive member side, it is naturally necessary to transmit the light. Therefore, when using natural light as an incident light and using the camera incident from the photosensitive member side, the thickness is about 1 mm. Transparent glass plates, plastic films and sheets are used.

The photosensitive electrode 7 is formed on the photoconductive layer support 5, except that metal is used as the photoconductive layer support 5. The material is not limited as long as the resistivity is 10 ⁶ Pa · cm or less, and an inorganic metal conductive film, an inorganic metal oxide conductive film, or the like is used.

Such a photosensitive electrode 7 is formed on the photoconductive layer support 5 by a method such as deposition, sputtering, CVD, coating, plating, dipping, electrolytic polymerization, and the like. In addition, the thickness must be changed depending on the electrical characteristics of the material constituting the photosensitive electrode 7 and the voltage applied to the information recording. For example, when the material is aluminum, the thickness is about 100-3000 kPa.

The optical characteristics described above are required when the photosensitive electrode 7 also needs to enter information light like the photoconductive layer support 5. For example, if the information light is visible light (400-700 nm), a transparent electrode such as sputtering, evaporating ITO (In ₂ O ₃ -SnO ₂ ), SnO ₂ or the like and coating their fine powder with ink to coat the binder Semi-transparent electrode, tetracyanoquinomimethane (TCNQ), polyacetylene, etc. coated with a method of depositing or sputtering Au, Pt, Al, Ag, Ni, Cr, etc. are used.

The electrode material may be used even when the information light is an infrared light of 700 nm or more, and in some cases, a colored visible light absorbing electrode may be used to block visible light.

In addition, even when the information light is ultraviolet light of 400 nm or less, the electrode material can be basically used, but it is not preferable that the material of the electrode substrate absorbs ultraviolet light (organic polymer material, soda glass, etc.) and quartz. Preferred are materials that transmit ultraviolet light, such as glass.

The photoconductive layer 9 is a conductive layer in which light carriers (electrons, holes) are generated in the irradiated portion when light is irradiated and such carriers can move the layer width, and the effect is remarkable especially when an electric field is present. The material is composed of an inorganic photoconductive material, an organic photoconductive material, an organic inorganic hybrid photoconductive material, and the like.

Hereinafter, the formation method of these photoconductive material and photoconductive layer is demonstrated.

(A) Inorganic Photoconductor (Photoconductor)

Inorganic photosensitive materials include amorphous silicon, amorphous serene, cadmium sulfide and zinc oxide.

(A) amorphous silicon photoconductor

As an amorphous silicon photoreceptor

① Hydrogenated amorphous silicon (a-Si: H)

② Fluorinated amorphous silicon (a-Si: F)

Not doped with impurities

B, Al, Ga, In, Il, etc., made into P type (hole transport type) by doping,

P, Ag, Sb, Bi or the like is doped with N type (electron transport type) by doping.

As a method for forming the photosensitive member layer, silane gas and impurity gas are introduced together with hydrogen gas in a low vacuum (10 ^{-2 -1} Torr), and deposited on an electrode substrate heated or unheated by a glow discharge to form a film or simply heated. It is formed by reacting thermochemically on an electrode substrate, or a solid material is formed by vapor deposition and sputtering, and used as a single layer or laminated. The film thickness is 1-50 micrometers.

Although charge is injected from the transparent electrode 7 and is not exposed, a charge injection preventing layer can be provided on the surface of the photoconductor electrode 7 in order to prevent the charge from being similarly exposed. As the charge injection prevention layer, an insulating layer such as an a-SiN layer, a SiO ₂ layer, an Al ₂ O ₃ layer or the like may be provided on one or both surfaces of the electrode substrate and the photoconductor uppermost layer (surface layer) by glow discharge, vapor deposition, sputtering, or the like. . If the insulating layer is made too thick, no current flows during exposure, so the thickness should be 1000 mV or less, and 400-500 mV is preferable considering the ease of manufacture.

As the charge injection prevention layer, a charge transport layer having a polarity and reverse polarity charge transport capability of the electrode substrate may be provided on the electrode substrate by using the rectifying effect.If the electrode is negative, the hole transport layer may be provided; Install. For example, a-Si: H (n ⁺ ) doped with boron in Si increases the transport characteristics of the hole, thereby obtaining a rectifying effect and functions as a charge injection preventing layer.

(B) amorphous serene photosensitive member

As an amorphous serene photosensitive member,

① Amorphous Serene (a-Se)

② Amorphous Serene Tellurium (a-Se-Te)

③ Amorphous arsenicene compound (a-As ₂ Se ₃ )

④ There is an amorphous arsenoseene compound + tellurium (a-As ₂ Se ₃ + Te).

The photosensitive member is fabricated by vapor deposition and sputtering, and SiO ₂ , Al ₂ O ₃ , SiC, and SiN layers are provided on the electrode substrate by vapor deposition, sputtering, glow discharge, or the like as the charge injection blocking layer. Moreover, it is good also as a laminated photosensitive member combining said (1)-(4). The film thickness of the photosensitive member layer is the same as that of the amorphous silicon photosensitive member.

(C) cadmium sulfide (CdS)

This photosensitive member is produced by coating, vapor deposition, and sputtering. In the case of deposition, solid particles of CdS are placed on a tungsten board and deposited by resistance heating or by EB (electron beam) deposition. In the case of sputtering, a CdS target is used to deposit on the substrate in argon plasma. In this case, CdS is usually deposited in an amorphous state, but a crystalline alignment film (oriented in the film thickness direction) can also be obtained by selecting the sputtering conditions. In the case of coating, CdS particles (particle size: 1-100 µm) are dispersed in a binder, and a solvent is added to coat S on a substrate.

(D) Zinc oxide (ZnO)

This photosensitive member is produced by a coating method or a CVD method. As a coating method, it is obtained by dispersing ZnO particles (particle size 1-100 탆) in a binder, adding a solvent and coating the coating on a substrate. In the CVD method, organic metals such as diethyl zinc and dimethyl zinc and oxygen gas are mixed in a low vacuum (10 ^{-2 -1} Torr) and chemically reacted on a heated electrode substrate (150-400 ° C) to deposit a zinc oxide film. Let's do it. Also in this case, the film orientated in the film thickness direction is obtained.

(B) organophotoreceptors

The organophotoreceptor includes a single layer photosensitive member and a functional separation type photosensitive member.

(A) Single-layer photosensitive member

The single layer photosensitive member is a mixture of a charge generating material and a charge transporting material.

[Charge Generation System]

Substances which absorb light and easily generate charges, for example, azone pigments, disazo pigments, tris azo pigments, phthalocyanine pigments, perylene pigments, pyrilium dyes, cyanine dyes and methine dyes are used. .

[Charge Transport Material System]

Substances having good charge transport properties such as hydrazone, pyrazoline, polyvinylcarbazole, carbazole, stilbene, anthracene, naphthalene, tridiphenyl methane, azine and amine , An aromatic amine type or the like is used.

In addition, a complex may be formed of a charge generating material and a charge transporting material to form a charge transfer complex.

Normally, the photosensitive member has a photosensitive characteristic determined by the light absorption characteristic of the charge generating material, but when the complex is formed by mixing the charge generating material and the charge transport material, the light absorbing property is changed. For example, polyvinylcarbazole (PVK) absorbs light only in the ultraviolet region, while trinitrofluorenone (TNF) absorbs light only in the vicinity of 400 nm wavelength, while PVK-TNF complexes emit light from the infrared region to 650 nm wavelength region. Absorbs and generates charge.

As for the film thickness of such a single layer photosensitive member, 10-50 micrometers is preferable.

(B) Function-sensitive photosensitive member

The charge generating material is easy to hop light but traps the charge, and the charge transport material has good charge transport properties, but does not absorb charge to generate charge. For this reason, the charge generating layer and the charge transport layer are stacked in such a manner that they are separated to sufficiently exhibit their respective characteristics.

[Charge Generation Layer]

Examples of the material for forming the charge generating layer include azo, disazo, trisazo, phthalocyanine, acid xanthene dyes, cyanine, styryl dyes, pyryllium dyes, perylenes, methine, a-Se, a-Si, azulenium salts, squalane salts, and the like.

[Charge transport layer]

Examples of the material for forming the charge transport layer include hydrazone, pyrazoline, PVK, carbazole, oxazole, triazole, aromatic amine, amine, triphenylmethane and polycyclic aromatic compounds. .

As a method of fabricating the functional separation photosensitive member, first, a charge generating material is doped with an binder resin on an electrode, and then a charge transporting layer is dissolved in a solvent together with a binder resin and applied to the charge transporting layer, and the film thickness of the charge generating layer is 0.1-10 탆. What is necessary is just to set the film thickness of a charge transport layer to 10-50 micrometers.

In addition, in any case of a single layer photosensitive member or a functional separation type photosensitive member, as a binder, a silicone resin, a styrene-butadiene copolymer resin, an epoxy resin, an acrylic resin, a saturated or unsaturated polyester resin, a polycarbonate resin, a polyvinyl acetal resin, a phenol resin , Polymethyl methacrylate (PMMA) resin, melamine resin, polyimide resin and the like are added to each of the charge generating material and the charge transporting material 0.1-10 parts for easy attachment. As the coating method, a dipping method, a vapor deposition method, a sputtering method, or the like can be used.

Next, the charge injection preventing layer will be described in detail.

The charge injection prevention layer is similar to that exposed to at least one or both surfaces of the photoconductive layer 9 even though the dark current (charge injection from the electrode) when the voltage of the photoconductive layer 9 is applied, i.e., is not exposed. Likewise, the photosensitive layer is provided to prevent the charge from moving.

The function of this charge injection prevention layer is demonstrated.

When a voltage is applied, almost no current flows to the photoconductive layer or the insulating layer surface by the charge injection prevention layer, but when light is incident, one of the charges generated in the photoconductive layer (electron or Hole), a high electric field is applied and current flows through the charge injection prevention layer.

The charge injection prevention layer is formed by stacking or stacking an inorganic insulating film, an organic insulating polymer film, an insulating monomolecular film, and the like, and the inorganic insulating film may be, for example, As ₂ O ₃ , B ₂ O ₃ , Bi ₂ O ₃ , CdS, CaO, CeO ₂ , Cr ₂ O ₃ , CoO, GeO ₂ , HfO ₂ , Fe ₂ O ₃ , La ₂ O ₃ , MgO, MnO ₂ , Nd ₂ O ₃ , Nb ₂ O ₅ , PbO, Sb ₂ O ₃ , SiO ₂ , SeO ₂ , Ta ₂ O ₅ , TiO ₂ , WO ₃ , V ₂ O ₅ , Y ₂ O ₅ , Y ₂ O ₃ , ZrO ₂ , BaTiO ₃ , Al ₂ O ₃ , Bi ₂ TiO ₅ , CaO-SrO, CaO-Y ₂ O ₃ , Cr-SiO, LiTaO ₃ , PbTiO ₃ , PbZrO ₃ , ZrO ₂ -Co, ZrO ₂ -SiO ₂ , AlN, BN, NbN, Si ₃ N ₄ , TaN, TiN, VN, ZrN, SiC, TiC, WC, Al ₄ C ₃ and the like are formed by methods such as glow discharge, vapor deposition, sputtering and the like. In addition, the film thickness of this layer is determined for each material used in consideration of the insulation which prevents the injection of electric charge. Next, the charge injection prevention layer using the rectifying effect is provided with a charge transport layer having a charge transport function of the polarity and reverse polarity of the electric substrate using the rectifying effect. The charge injection prevention layer is formed of an inorganic photoconductive layer, an organic photoconductive layer, and an organic inorganic composite photoconductive layer, and the film thickness thereof is about 0.1-10 mu m. Specifically, when the electrode is negative, an amorphous silicon photoconductive layer doped with B, Al, Ga, In, etc., amorphous serene or oxadiazole, pyrazoline, polyvinylcarbazole, stilbene, anthracene, naphthalene, tridiphenyl Organic photoconductive layer formed by dispersing methane, triphenylmethane, adine, amine, aromatic amine, etc. in resin; amorphous silicon photoconductive layer doped with P, N, As, Sb, Bi, etc. The entire layer is formed by a method such as glow discharge, vapor deposition, sputtering, CVD, coating, or the like.

Next, the material of the information holding medium and the manufacturing method of the information holding medium will be described.

The information holding medium 3 is used together with the photosensitive member 1 to record information as a distribution of electrostatic charges on the surface or inside of the insulating layer 11 constituting the information holding medium 3. It is used as a medium. Therefore, the information holding medium can take various forms depending on the information to be recorded or the recording method. For example, when used in electrostatic cameras, it becomes a general film (single comma, continuous coma) shape or a disc shape, and when recording digital or analog information by a laser or the like, a tape shape, a disc shape or a card shape do.

Although the insulating layer support 15 supports the information holding medium 3 as described above, it is basically made of the same material as that of the photoconductive layer support 5, and the same light transmittance may be required. Specifically, when the information bearing medium 3 has a flexible film, tape, or disk shape, a flexible plastic film is used, and when strength is required, an inorganic material such as a rigid sheet or glass is used. .

The case where the information bearing medium 3 has the shape of a flexible film, a tape, and a disk will be described. First, as shown in Fig. 1 (e), there is a type in which the resin layer 11 is continuous.

This is done by forming a resin layer on a support such as a plastic film provided with an electrode layer, leaving both sides of the support or on the entire surface. The information holding medium has a length of at least two times or more the length of one screen to be recorded (e.g., a coma in case of camera acquisition, track width of digital information recording). As a matter of course, a plurality of pieces of the information holding medium are joined to each other in the longitudinal direction to be formed. In this case, there may be a slit band of resin layer missing between adjacent resin layers.

As shown in Fig. 1 (f), there is a type in which the resin layer 11 is discontinuous in the longitudinal direction.

The resin layer is formed by discontinuously in the longitudinal direction with or without leaving both sides of the support on a support such as a plastic film, a plurality of resin layers are formed on the support to a certain size. The size of the resin layer also varies depending on the exposure method of the image and the information input device, but is 36 mm x 24 mm in the case of an image dimension such as a 35 mm camera, and digital information recording in the case of spot input such as a laser beam. The track width. In addition, in the case of digital information recording, the resin layer missing portion formed between adjacent resin layers can be used as a tracking stand when inputting and outputting information. Further, a plurality of pieces of information holding medium joined in the longitudinal direction may be included, and at this time, there may be a slit zone of the resin layer missing portion between adjacent resin layers.

As shown in Fig. 1G, there is a type in which the resin layer is discontinuous in the width direction.

In this type, a resin layer is formed on a support such as a plastic film provided with an electrode layer discontinuously in the width direction without leaving both sides of the support, and a plurality of strip-shaped resin layers are formed on the support. The width of the resin layer is equal to or greater than the track width of the recorded digital information, and the resin layer missing portion formed between adjacent resin layers is used as a tracking stand when inputting and outputting information.

Further, as shown in Fig. 1 (h), there is a disc type type.

This type is formed to have a vortex-shaped resin layer missing portion having a resin layer on the front or connected to a support such as a circular plastic film provided with an electrode layer. In this information bearing medium, a circular missing for driving the input / output device may be formed. In the case of the digital information recording section, the continuous spiral resin layer missing section can be used as a tracking stand when inputting / outputting information.

The information holding medium electrode 13 may basically be the same as the photosensitive electrode 7, and is formed on the insulating layer support 15 by the same formation method as the photosensitive electrode 7 described above.

Since the insulating layer 11 records information on the surface or inside thereof as a distribution of electrostatic charges, it is required to have high insulating property and to have a specific resistance of 10 ¹⁴ Pa · cm or more in order to suppress charge transfer. The insulating twelve 11 may dissolve resins and rubbers in a solvent to form a charge by coating, dipping, vapor deposition, or sputtering.

Therefore, as the resin and rubber, for example, polyethylene, polypropylene, vinyl resin, styrol resin, acrylic resin, nylon 66, nylon 6, polycarbonate, acetal homopolymer, fluorine resin, cellulose resin, phenol resin, glass sub resin, poly Ester resin, epoxy resin, flammable epoxy resin, melamine resin, silicone resin, phenooxy resin, aromatic polyimide, PPO, polysulfone, etc., polyisoprene, polybutadiene, polychloroprene, isobutylene, nitrile rubber. A single substance or mixture of rubbers such as polyacrylic rubber, chlorosulfonated polyethylene, ethylene, propylene rubber, fluorine rubber, silicone rubber, polysulfide synthetic resin, urethane rubber, and the like are used.

In addition, a silicon film, a polyester film, a polyimide film, a fluorine-containing film, a polyethylene film, a polypropylene film, a polyparabanic acid film, a polycarbonate film, a polyamide film, or the like is placed on the information bearing electrode 13 with an adhesive or the like. The layer may be formed by adhering to a layer, or a layer may be formed by coating and dipping by adding a curing agent, a solvent, and the like necessary for a thermoplastic resin, a thermosetting resin, an infrared curable resin, an electron beam curable resin, and a rubber.

As the insulating layer 11, a monomolecular film or a monomolecular film formed by the Langmuir project method can also be used.

In addition, the insulating layer 11 can be provided with a charge holding enhancement layer on the insulating layer 11 or with the electrode surface. Charge holding strengthening layer is strong electric field (10 ⁴ V / ㎝ later) is applied, but when the charge is injected, that an electric field (10 ⁴ V / ㎝ below) refers to the layer charge is not injected. As the charge holding steel layer, SiO ₂ , Al ₂ O ₃ , SiC, SiN, and the like are used. As the organic material, a polyethylene vapor deposition film, a polyparaxylene vapor deposition film, or the like is used.

In order to maintain the electrostatic charge more stably, a material having an electron donating material (donor material) or a material having an electron accepting property (acceptor material) may be added to the insulating layer 11. As donor materials, there are styrene-based, ethylene-based, naphthalene-based, anthracene-based, pyridine-based and adine-based compounds. Polyvinylpyrene, polystyrene, etc. are used and it uses one kind or it mixes. As the acceptor material, there are halogen compounds, cyan compounds, nitro compounds, and the like. Specifically, tetracyanoquinomimethane (TCNQ), trinitrofluorenone (TNF), and the like are used. Donor material and acceptor material are used by adding about 0.001-10% with respect to resin.

Further, fine particles can be added to the information bearing medium to keep the charge stable. Examples of the particulate material include periodic table group IA (alkali metal), copper IB (cognate), copper IIA (alkaline earth metal), copper IIB (zinc), copper IIIA (aluminum), copper IIIB (rare earth) , East IVB group (Titan group), East VB group (Vanadium group), East VIB group (Chromium group), East VIIB group (Manganese group), East VIII group (Steel, Platinum group), East IVA group (Carbon group) ), Silicon, germanium, silver, lead, copper VA (nitrogen), antimony, bismuth, copper VIA (oxygen), sulfur, serene, tellurium are used in the form of fine powder. Metals in the particulate material can also be used in the form of ions, finely divided alloys, organometallics, and complexes. Further, the particulate material can be used in the form of oxides, phosphorous oxides, sulfur oxides, and halides. These additives may be added only slightly to the information holding medium such as the resin or rubber described above, and the amount of addition may be about 0.01-10% by weight relative to the information holding medium. In addition, the insulating layer 11 has a thickness of 1000 kPa (0.1 µm) or more in terms of insulation properties, and 100 µm or less is preferable when flexibility is required.

The insulating layer 11 thus formed can be provided with a protective film on its surface in order to prevent breakage or discharge of information charges on the surface thereof. As a protective film, rubber | gum, such as silicone rubber | gum which has adhesiveness, resins, such as polyterpene, may be made into a film form, and it may adhere | attach on the surface of the insulating layer 11, or a plastic film may adhere | attach using an adhesive agent, such as silicone oil, Although it resists 10 ⁴ Ω · m or more. The film thickness is about 0.5-30 mu m, and when the information of the insulating layer 11 needs to be high resolution, the protective film should be thin. When the information is reproduced, the protective film may reproduce information on the protective film, or the protective film may be peeled off to reproduce the information of the insulating layer.

As an electrostatic charge maintaining method, there is an electret that generates electric charge distribution and polarization in the insulating medium, in addition to the method of depositing an electrode on the surface as described above.

FIG. 2 is a diagram showing a static charge holding method using an optical electret, in which the same numerals as in FIG. 1 indicate the same contents. 19 is a transparent electrode.

As shown in Fig. 2 (a), an electrode 13 is formed on a support 15 such as a film, and ZnS, CdS, and ZnO are deposited on the electrode plate by one layer 1-5 by sputtering, CVD, coating, or the like. Μm is formed. When the transparent electrode 19 is stacked on the surface of the photosensitive layer by contact or non-contact and exposed in a voltage applied state (figure 2 (b)), electric charges are generated by the light in the exposed portion and polarized by the electric field. Even if the electric field is removed, it is trapped at that position (Fig. 2 (c)). In this way, the electret according to the exposure amount is obtained. In addition, the information bearing medium of FIG. 2 has an advantage of not requiring a separate photosensitive member.

3 is a diagram showing a static charge holding method using a thermal electret, and the same numerals as those in FIG.

Examples of thermal electret materials include polyvinylidene fluoride (PVDF), poly (VDF / ethylene trifluoride), poly (VDF / tetrafluoroethylene), polyvinyl fluoride, polyvinylidene chloride, polyacrylonitrile, and poly- α-chloroacrylonitrile, poly (acrylonitrile / vinyl chloride), polyamide 11, polyamide 3, poly-m-phenyleneisophthalamide, polycarbonate, poly (vinylidene cyanide vinyl acetate), PVDF / PZT composites, etc., which are provided on the electrode substrate 13 in a 1-50 µm single layer or are laminated in two or more kinds.

Then, the medium is heated above the glass transition temperature of the medium material by resistance heating or the like before exposure, and voltage application exposure is performed in that state (Fig. 3 (b)). At high temperatures, the mobility of the ions increases, and in the exposed portion, a high electric field is applied to the insulating layer, and the positive electrode charged in the thermally activated ions and the negative electrode charged in the electrostatic charge form a space charge and cause polarization. After that, when the medium is cooled, the generated charge is trapped at the position even if the electric field is removed, thereby generating an electret according to the exposure amount (Fig. 3 (c)).

Next, as a method of inputting information into the insulating layer 11, there is a method using a high resolution electrostatic camera or a recording method using a laser. First, the high-resolution electrostatic camera used in the present invention opposes the photoconductor 1 and the photoconductor 1, which is a photoconductive layer 9 having a photoconductor electrode 7 on the front surface instead of a photo film used in a conventional camera. The recording member is composed of an information holding medium, which is an insulating layer 11 having an information holding medium electrode 13 formed on the rear surface thereof, the voltage is applied to both electrodes, and the photoconductive layer is made conductive according to the incident light, and the insulating member 11 is insulated according to the amount of incident light. By accumulating charge on a layer, an electrostatic latent image of an incident optical is formed on a charge storage medium, and a mechanical shutter can be used, and an electric shutter can also be used. It is possible to maintain. In addition, a filter is used to separate the optical information into R, G, and B light components by a prism and to extract the light information as parallel light, and to form one commer from three sets of R, G, and B resolved information holding media, It is also possible to take color photographs by arranging the G, B phases side by side and making one commer in one set.

As the laser recording method, argon lasers (514, 488 mm), helium-neon lasers (633 mm), semiconductor lasers (780 mm, 810 mm, etc.) may be used as the light source, and the photosensitive member and the information holding medium may be used. The surface is in close contact with each other or at regular intervals to face each other. In this case, the photoconductor electrode having the same polarity as that of the carrier of the photoconductor may be prepared. In this state, laser exposure corresponding to an image signal, a text signal, a code signal, and a line signal is performed by scanning. Analog recording such as an image is performed by modulating the light intensity of the laser, and digital recording such as text, code, and line drawing is performed by on-off control of the laser light. In the case where a dot is formed in an image, dot generator on-off control is performed on the laser beam. In the photoconductor, the spectral characteristics of the photoconductive layer need not be panchromatic, and may be sensitive to the wavelength of the laser light source.

Next, information recording in a type other than electric charge will be described.

4 is a view for explaining the information recording and reproducing processing method of the present invention using the photoconductive fine particles. In the drawings, 1 is a photosensitive member, 5 is a support, 7 is an electrode, 9 is a photoconductive layer, 3 is an information carrier, 21 is a thermoplastic insulating layer, 13 is an electrode, 15 is a support, 23 is a fine particle layer, 25 is a photomultiplier, 27 is a laser light.

First, in FIG. 4A, when image exposure is performed while applying a voltage between the photoreceptor 1 and the positive electrode of the electrostatic sustaining medium 3, electric charges are accumulated in the exposed portion on the information bearing medium. Next, as shown in FIG. 4 (b), carriers are generated in the fine particles by totally exposing the information holding medium, and the surface accumulation charge and the reverse polarity charge are neutralized with the surface charge. The charge of the sex remains in the vicinity of the fine particles and is injected into the vicinity of the fine particles.

As the fine particles for storing the charge, a conductive material may be used in addition to the photoconductive material. The charge accumulation method in this case will be described later.

As the photoconductive fine particle material, inorganic photoconductive materials such as amorphous silicon, crystalline silicon, amorphous serene, crystalline cerene, cadmium sulfide, and zinc oxide or organic photoconductive materials such as polyvinylcarbazole, phthalocyanine and azo pigments are used.

In addition, as the conductive material, periodic table group IA (alkali metal), copper IB (copper), copper IIA (alkaline earth metal), copper IIB (zinc group), copper IIIA (aluminum group), copper IIIB ( Rare earth), East IVB group (Titan group), East VB group (Vanadium group), East VIB group (Chromium group), East VIIB group (Manganese group), East VIII group (Iron group, Platinum group), East IVA group (Carbon) As a group), carbon, silicon, germanium, silver, lead, copper VA group (nitrogen group), and antimony, bismuth, and copper VA group (oxygen group), sulfur, serene, tellurium are used in the form of fine powder. In the conductive material, metals can be used in the form of metal ions, finely divided alloys, organic metals, and complexes. In addition, the conductive material may be used in the form of oxides, phosphorous oxides, sulfur oxides, halides. In particular, carbon, gold, copper, aluminum or the like is preferably used.

In the case of using conductive fine particles, a method of accumulating charge will be described with reference to FIG. 5. Although the same numbers as those in FIG. 4 in the drawings are the same, the difference in that the fine particles 23 are conductive is different.

First, in Fig. 5A, when image exposure is performed while applying a voltage between the photoreceptor 1 and the positive electrode of the information holding medium 3, electric charges are accumulated in the exposed portion on the surface of the information holding medium. On the other hand, since there are many electrons and electrostatic charges in the conductive fine particles, charges accumulate on the surface, and at the same time, the surface charges and the reverse polarity charges in the conductive fine particles are neutralized. And injected into the fine particles.

Next, the formation method of a microparticle layer is demonstrated.

First, a fine particle layer is formed by using a vacuum evaporation apparatus to deposit a single layer or a plurality of layers in the vicinity of the surface of the resin layer, and depositing the particle layer forming material on a resin layer in an uncured, molten or softened state laminated on a support. . Particle layer-like materials are coagulated by evaporation under a vacuum of about 10-10 ^-3 Torr to form a fine particle having a diameter of about 10-0.1 μm. For example, when the resin layer is softened by heating during deposition, fine particles It is laminated on a single layer or on a plurality of layers in an orderly manner near the inside of the stratum surface. If the resin layer is a thermoplastic resin, the resin layer is softened by resistance heating of the electrode layer, or the substrate is directly heated by a heater or the like to soften the resin layer, and if the resin layer is a thermosetting resin, an ultraviolet curable resin, or an electron beam curable resin, The particle layer forming material is deposited in an uncured state to form a particle layer, and then cured with a suitable curing means.

As another means for forming the fine particle layer in the vicinity of the surface of the resin layer, the particle layer is deposited in a single layer or in a plurality of layers on the support on which the resin layer is formed and cured on the electrode substrate in advance. In this case, the particle layer is formed on the resin layer surface. After this, the same or different insulating resin as the resin used for forming the resin layer was laminated in the range of 0.1 µm to 30 µm, and as the lamination method, the resin layer was directly formed by vacuum deposition, sputtering, or the like. As the wet method, a solution in which the resin is dissolved in a solvent may be used, and the solvent may be dried after forming a film by spinner coating, dipping, plate coating, or the like. Moreover, in order to make particle size uniform at the time of formation of a particle layer, you may add the temperature on the board | substrate about the grade which a resin layer does not melt.

In this manner, in the state in which charge is injected into the fine particles, charges accumulated in the fine particles and reverse polarity charges are induced in the electrode 103b, and an electric field is formed in the insulating layer by the fine particle charges and the charges held in the electrodes. have. In this state, when the information holding medium is heated to a softening point or higher, the insulating layer becomes soft, so that the charged fine particles adhere to the electric field and are dispersed in the insulating layer.

On the other hand, the fine particles in the unexposed portion remain in their original positions because the electric field does not exist even when the insulating layer softens. Thus, when the information holding medium is cooled, the fine particles in the exposed portion are immobilized in a form dispersed therein. Examples of the insulating layer include polyethylene, vinyl chloride resin, polypropylene, styrene resin, ABS resin, polyvinyl alcohol, acrylic resin, acrylonitrile-styrene resin, vinylidene chloride resin, AAS (ASA) resin, AES resin, Thermoplastic resins such as fibrous derivative resins, thermoplastic polyurethanes, polyvinyl butyral, poly-4-methylpentene-1, polybutene-1, and rodin ester resins may be used.

Next, as shown in Fig. 4 (d), when the laser light is irradiated onto the information holding medium and received by the photomultiplier 25 on the opposite side, the laser light is transmitted through the area where the fine particles are dispersed and unexposed. Where the fine particles are two-dimensionally layered at the portion, the laser light does not transmit, and thus the transmitted light is not detected. In this way, the laser scan can be used to read the pattern of which region the fine particles are dispersed. Of course, the reflection of the electrode is detected by the electrode as the reflected light instead of the transmitted light, and the unexposed part is absorbed by the fine particles, so that the reflected light is not detected, so that the pattern can be read.

Since the surface of the unexposed portion is not formed with frost as in the prior art, it is possible to read accurately because there is no influence of diffuse reflection or scattering by the portion.

Fig. 6 is a diagram showing an embodiment in which information accumulation is performed by forming irregularities on the surface of the information holding medium.

In this embodiment, as shown in FIG. 6 (a), charges are accumulated in a pattern pattern on the insulating layer 21 made of thermoplastic resin by voltage application exposure, and then the charge (information) holding medium 3 is formed. Heat it. Since the surface charge and the reverse polarity charge are induced in the electrode 13 corresponding to the portion where the charge is accumulated, an electric field is generated inside and the electric charge is attracted in the electric field direction. As a result, the unevenness 31 as shown in FIG. 6 (b) is formed on the surface of the plasticized by heating, and this unevenness is fixed and recorded as information by cooling the information holding medium. For example, the unevenness causes irregular reflection in the uneven portion when light is irradiated, so that the presence or absence of unevenness can be read by transmitted light or reflected light, and information can be reproduced. In addition, the charge on the surface leaks during the heating process and most of it disappears.

7 is a view showing an embodiment of the information recording and reproducing processing apparatus of the present invention, in which 3 is an information holding medium, 41 is an electrostatic potential measuring means, 43 is an A / D converter, and 45 is a built-in CPU control. The processing apparatus 47 denotes scanning driving means, and 49 denotes a display portion.

The electrostatic latent image is recorded on the information holding medium 3 by the method described with reference to FIGS. As described later, the electrostatic potential measuring means 41 is a contact type, a non-contact type, or a DC amplification type, AC amplification type, current collector type, electron beam type, CT scan type, electron beam type, or the like. The potential at any one of the points is read as a signal and output as an analog signal. The detected analog potential signal is converted into a digital signal by the A / D converter 43 so as to be suitable for processing in the control processing device 45 such as a microcomputer. The converted digital signal is introduced as data of any point measured on the information bearing medium 3. Thus, after the data at any one point on the information holding medium 3 is introduced, the control processing device 45 drives the scan driving means 47 serving as the XY stage or the like to drive the information holding medium 3. It scans and collects data in each part on the information holding medium 3. As shown in FIG. Of course, you may scan-drive the probe of the electrostatic potential measuring means.

It also drives the information maintenance media. It is also possible to scan the information holding medium two-dimensionally by driving the electrostatic potential measuring means by negative scanning.

The electrostatic latent image data thus read is image-processed in the control processing device 45 as necessary and displayed on the display unit 49. It goes without saying that the printer can be connected and printed out as needed.

FIG. 9 is a diagram showing the edges of the potential distribution at Y = 8 mm when an image as shown in FIG. 8 is formed in an area of X = 15 mm and Y = 15 mm. In FIG. 9, it can be seen that a potential distribution of min = 100 V and MAX = 163 V is detected.

FIG. 10 shows an example in which the potential on the information holding medium 3 on which the image as shown in FIG. 8 is formed is scanned and read, and image processing is applied to display the potential.

Various types of imaging can be performed by introducing such electrostatic latent images as data and processing the data. In addition, since the data is introduced as data, the noise may be integrated, the data may be reduced, or data may be partially corrected, and the image may be used for recording on other recording media as necessary. It is also possible to select and output an arbitrary part at any time and to reproduce it repeatedly.

In addition, in order to introduce information recorded two-dimensionally on the information holding medium as data, it is necessary to move and scan the probe and / or information holding medium of the measuring device.

In the scanning method, (1) a method of using a stepping motor that moves to a measurement position, stops and makes a measurement and then equalizes it to the next position; (2) sets it to move at a constant speed and repeats the measurement at a predetermined timing. There is a method such as operating in response to the data and the measurement position obtained by.

According to the method of ①, the position can be precisely controlled, but there is a drawback in that the scanning time becomes long. Therefore, in order to shorten the data collection time, it is preferable to use the method of ② which scans the movement at a constant speed.

FIG. 11 is a diagram showing an example of the potential introduction method in the information recording and reproducing processing apparatus of the present invention, wherein the same numbers as in FIG. 1 denote the same contents. In the figure, 51 is a portion for reading potential, 53 is a detection electrode, 55 is a guide electrode, 57 is a capacitor, and 59 is a voltmeter.

When the portion 51 for reading the potential is opposed to the charge accumulation surface of the information holding medium 3, the electric field generated by the charge accumulated on the insulating layer 11 of the information holding medium 3 at the detection electrode 53 And an induced charge equal to the charge on the information bearing medium on the detection electrode surface. Since the capacitor 57 is charged with the same amount of charge opposite to the induced charge, a potential difference occurs due to accumulated charge between the electrodes of the capacitor, and this value is read by the voltmeter 59 to obtain the potential of the information carrier. Can be. The electrostatic latent image can be output as an electric signal by scanning the surface of the information holding medium in the portion 51 for reading the potential. In addition, since only the detection electrode 53 acts on the electric field (electric force line) due to a wider range of charge than the detection electrode opposing portion of the information bearing medium, the resolution decreases, so that the grounded guide electrode 55 is arranged around the detection electrode. You may also As a result, since the electric force lines are directed perpendicular to the plane, the electric force lines of only the portions facing the detection electrodes 53 act, so that the potentials of the portions approximately equal to the detection area can be read. Since the accuracy of reading potential, resolution, and the like vary greatly depending on the shape and size of the detection electrode and the guide electrode, and the distance between the information holding medium, it is necessary to design the optimum condition according to the required performance.

FIG. 12 is a view showing another example of a method of reading a potential, and is similar to the case of FIG. 11 except that the detection electrode and the guide electrode are provided on the insulating protective film 61 and the potential is detected with the insulating protective film interposed therebetween. .

According to this method, since it can detect by contacting an information holding medium, the space | interval with a detection electrode can be made constant.

Fig. 13 is a view showing another example of the method of reading the potential, and the needle-shaped electrode 63 is directly contacted to the information holding medium to detect the potential of the portion, so that the detection area can be made small, so that high resolution can be obtained. Can be. In addition, when a plurality of needle-shaped electrodes are provided and detected, the reading speed can be improved.

The above is of the DC amplification type which detects a DC signal by contact or non-contact, Next, the example of an AC amplification type is demonstrated.

Fig. 14 shows a method of reading the potential of the vibrating electrode type, where 52 is a pull-up electrode, 54 is an amplifier, and 56 is a meter.

The detection electrode 52 is advanced and driven so as to change the distance with respect to the charging surface of the information holding medium 3, so that the potential at the detection electrode 52 is temporally changed in amplitude according to the electrostatic potential of the charging surface. To change. This temporal potential change is taken out as the voltage change across the impedance Z, the AC component is amplified by the amplifier 54 through the capacitor C, and read by the meter 56, and then the electrostatic potential of the charging surface is read. Can be measured.

Fig. 15 shows an example of a rotary detector, in which 58 is a rotor blade.

A conductive rotary blade 58 is provided between the electrode 52 and the charging surface of the information bearing medium 3, and is electrically driven by driving means (not shown). As a result, the detection electrode 52 and the information holding medium 3 are electrically shielded periodically. Therefore, the detection electrode 52 detects a potential signal whose amplitude periodically changes according to the electrostatic potential of the charging surface, and amplifies this AC component with the amplifier 54 and reads it out.

Fig. 16 shows an example of the vibration capacitance detector, where 58 is a drive circuit and 60 is a vibration piece.

The condenser capacitance is changed by vibrating the vibrating piece 60 of the electrode while forming the condenser by the vibrating circuit 58. As a result, the DC potential signal detected by the detection electrode 52 is modulated and amplified and detected by this AC component. The detector converts direct current into alternating current and can measure potentials with high sensitivity and stability.

Fig. 17 is a diagram showing another example of a method of reading a potential, in which potential detection is performed using a long elongated detection electrode using a CT method (computer tomography imaging method).

When the detection electrodes 65 are arranged so that the charge storage plane is cut off, the obtained data is divided according to the detection electrodes, that is, data corresponding to the projection data in CT is obtained. Therefore, this detection electrode is scanned so as to spread evenly over the entire surface as shown by the arrow in FIG. 17 (b), and by changing the angle θ similarly, the necessary data is collected and a CT algorithm is used for the collected data. By performing the arithmetic processing, the potential distribution state on the information holding medium can be obtained.

As shown in Fig. 18, when the plurality of detection electrodes are arranged side by side, the data collection speed can be increased, and the overall processing speed can be improved.

Fig. 19 shows an example of a current collector, in which 62 is a grounded metal cylinder, 64 is an insulation, and 66 is a current collector.

The current collector 66 contains a radioactive material, and α rays are emitted from the current collector 66. For this reason, the inside of the metal cylinder is ionized to form a positive ion band. In the natural state, these ions disappear due to recombination and diffusion, and remain in equilibrium. However, when there is an electric field, the collision with the air molecules is repeated by thermal motion, and statistically proceeds in the direction of the electric field. It serves to carry.

In other words, the air conducts due to the ions, so that an equivalent electric resistance path exists between the objects including the current collector 66 and the surroundings.

Therefore, the resistance between the charging surface of the information bearing medium 3 and the ground metal cylinder 62, the electric charge and the current collector 66, and the current collector 66 and the ground metal cylinder 62, respectively, R ₀ , R ₁ , R ₂ , and the potential of the electric charge is V ₁ , the potential V ₂ of the current collector 66 is in a steady state.

V ₂ = R ₂ V ₁ / (R ₁ + R ₂ )

It becomes As a result, the potential of the information holding medium 3 can be obtained by reading the potential of the current collector 66.

Fig. 20 shows an example of an apparatus for reading out an electron beam potential, where 67 is an electron gun, 68 is an electron beam, 69 is a first die node, and 70 is a secondary electron multiplication section.

Electrons from the electron gun 67 are deflected by an electrostatic deflection or an electron deflecting device (not shown) to scan the charged surface. Part of the scanning electron beam is coupled with the charge on the charging surface, so that the charging current flows, so that the potential of the charging surface is lowered to the equilibrium potential. The rest of the modulated electron beam returns to the direction of the electron gun 67 to impinge on the first die node 69, and the secondary electrons are amplified by the secondary electron multiplier 70 and taken out as a signal output at the anode. Reflected electrons or secondary electrons are used as this returning electron beam.

In the case of the electron beam type, a uniform charge is formed on the medium after scanning, but a current corresponding to the latent image is detected at the time of scanning. In the case where the latent image is negatively charged, the portion where the charge is large (exposure portion) is reduced by the electrons and the layer charge current is small, but the maximum charge current flows in the portion where no charge exists. In the case of positive charges, the opposite becomes negative.

21 is a view showing another example of a method of reading a potential, toner developing an information bearing medium 3 having an electrostatic latent image, irradiating a colored surface with a light beam, and scanning the reflected light. 71), the high resolution can be achieved by reducing the diameter of the light beam, and the electrostatic potential can be easily detected optically.

22 is a view showing another example of a method of reading a potential, and as described later, R, G, and B resolved images formed by a fine color filter are toner-shaped, and the colored surface is irradiated with a light beam, An example of the case where the Y, M, and C signals are obtained by the reflected light is shown. In the drawing, reference numeral 83 denotes a scanning signal generator, 85 denotes a laser, 87 denotes a reflector, 89 denotes a half mirror, 71 denotes a photoelectric converter, and 93, 95, and 97 gate circuits. to be.

With the scanning signal from the scanning signal generator 83, the laser beam from the laser 85 is exposed to the colored surface via the reflector 87 and the half mirror 89 and scanned. The reflected light from the colored surface is incident on the photoelectric transducer 71 through the half mirror 89 and converted into an electric signal. When the gate circuits 93, 95, 97 are opened and closed at the same time as the signal from the scan signal generator 83, the gate circuits 93, 95, 97 are opened and closed at the same time as the pattern of the fine filter. Signals of Y, M, and C can be obtained without coloring in, M, and C.

The same Y, M, and C signals can be obtained even when the color image is divided into three sides as described later, and in this case, the same color does not need to be colored on Y, M, and C.

In the electrostatic potential detection methods shown in FIGS. 21 and 22, it is preferable that the toner image has a gamma characteristic corresponding to the charge amount of the electrostatic latent image, and therefore it is preferable that the toner image does not have a threshold against an analog change in the charge amount. However, if only the correspondence is given, the gamma correction may be performed by an electrical process even if the gamma characteristics do not coincide.

In the information recording and reproducing process of the present invention, information read from the information holding medium can be output by various printers.

23 to 25 are diagrams showing an example in which an optically read color image is output to a sublimation transfer printer. In the drawing, 101 is a laser, 103a is a reflecting mirror, 103b, 103c is a dichroic mirror, 105 is a reflecting mirror, 107 is a scanning system, 109 is a reflecting mirror, 111 is a half mirror, 113a, 113b is a dichromir mirror, 113c 1 is a reflection mirror, 115 is a photoelectric converter, 117 is a memory, 119 is an image processing apparatus, 121 is a complementary color converter, 123 is a parallel converter, 125 is a driver, 127 is a head, 129 is a platen roller, and 131 is an award paper.

R, G, and B light from the laser 101 are united through the reflecting mirror 103a and the dichroic mirrors 103b and 103c, and the reflecting mirror 105, the scanning system 107, and the reflecting mirror 109 ), The information bearing medium 3 is scanned through the half mirror 111. It is assumed that the information bearing medium 3 is colored by toner development of R, G, and B resolved images formed by the fine color filter. The scanning system 107 is made of galvano mirrors 107a and 107b which scan in the X and Y directions. In this way, the reflected light obtained by scanning the surface of the information holding medium is color-separated into R, G, and B by the mirror 113 through the half mirror 111, and is converted into an electrical signal by a photoelectric converter, respectively, and is read back into the memory 117. . Pixel density conversion, color correction, gradation correction, etc. are performed by the image processing apparatus 119 as necessary, and are converted to color signals of Y, M, and C in the complementary color converter 121 because they are for printing. ) Is converted into a serial signal for each line and applied to the driver 125 to drive and control the thermal head 127 at a duty ratio according to the color signals of Y, M, and C, and the receiving paper 131 on the thermal transfer film 130. Is transferred to). If necessary, at the same time as the complementary color conversion, a BK (black) signal other than Y, M, and C may be generated. In such a case, the thermal range of the shadow side of the hard copy can be widened by using black thermal transfer film and recording in four colors.

Fig. 24 shows the transfer mechanism from the transfer film to the image paper.

The transfer film is laminated with a primer in order to make the heat-resistant active layer 130a, the transfer base material 103b, and the sublimation transfer layer 130c adhere well to the coating material base. As the heat-resistant active layer 130a, a mixture of polyvinylbutylal, polyisocyanate, phosphate ester, and transfer base material 130b, such as polyethylene terephthalate and polyimide, such as indaniline-based, non-razorone-based Sublimable dyes, such as a crude type | system | group, polyvinyl acetal, and cellulose-type binders.

The water phase paper 131 is formed by laminating a water layer 131b, a water base material 131a, and a back layer 131c with a primer therebetween, and the water layer 131b may be a saturated polyester, vinyl chloride, or the like. The base material 131a is a synthetic paper, a foamed polycaster, a foamed polypropylene, and the back layer is made of a binder, a lubricant, a coating agent, and the like, respectively.

Around the platen roll 129, the water receiving layer 131b and the water receiving paper base material 131a are wound around the platen layer 131, and the transfer film 130 is stacked on the sheet. The sublimation transfer dye is heated and sublimed by contacting the back surface of the transfer film 130 with heat and then dyed by adhering to the aqueous layer 131b. In the above example, the signal read out from the information bearing medium is digitally image-processed. However, since the dye sublimation is vaporized and transferred to the aqueous layer by the amount of heat applied, the gray level can be recorded according to the amount of heat for each pixel dot. The printout can be performed directly on the output of the information holding medium on which recording is to be performed, without the necessity of applying dot processing or the like. In this way, the sublimation transfer printer can express the image signal of the information holding medium on which high resolution analog recording is performed in the unit of dots, which is very suitable for application of the present invention.

The recording of the latent image on the information bearing medium is extremely accurate because the resolution of the charge size can be obtained. However, at the present position, the reading method has not been developed with a precision comparable to this. However, at present, 2 ⁸ gray scale images are obtained at 1 µm x 1 µm. This is an information holding medium of 1 cm x 1 cm, which corresponds to a storage capacity of 100 MBytes, and can store two pieces of color print image data of A4 size. Incidentally, in the above example, the toner-developed information bearing medium is optically read, but it goes without saying that the phase potential of the information bearing medium may be read electrically.

FIG. 25 shows an example of a pattern of a sublimation transfer film, in which dyes of C, M, and Y are coated and separated in a plane order, which is wound on a drum and coated with an aqueous layer to apply an aqueous layer to one rotation of the drum. When one color and black (BK) also enter, printing is complete | finished by apply | coating four times in total.

In addition, in the information recording and reproducing process of the present invention, a fused thermal transfer film may be used.

As shown in FIG. 26, the fusion-type thermal transfer transfers the ordinary paper 145 between the rubber roll 141 and the transfer film 147, and heats the transfer film in accordance with the image data with the thermal head 143. When the amount of heat applied to the melt transfer layer (wax) applied to the base film 147b is greater than or equal to a predetermined value, it is melted and transferred to the plain paper 145. If it is less than or equal to the predetermined value, it is not transferred, but it is binarized and stored in the pixel dot unit. Therefore, unlike the case of sublimation transfer, the gradation is displayed as the ratio of the number of recording dots to the number of dots constituting one pixel.

In addition, an inkjet printer may be used in which ink is jetted into small droplets and made to fly, and the ink dot is attached to the recording paper in a pattern according to an image to record the ink.

In addition, it can be applied to microcapsules. When the microcapsules of the micrometer unit containing the monomer, the leuco dye, and the reaction initiator were applied thinly on the paper and irradiated with ultraviolet light or visible light and the receptor coated with acidic clay, the amount of irradiation light was more than a predetermined value. The microcapsules in which the polymerization proceeded were not broken, and the microcapsules having low debt exposure were broken, and the leuco dye came out of the capsule and stuck to the acidic clay to dye. In this case, if the microcapsules are made of materials of R, G, and B colors, and the leuco dyes in the inside are in a relation between the capsule and the complementary color, for example, when the R light is irradiated, the monomer of R is polymerized. Because of this, C does not come out of the capsule because of this, while the capsules of G and B are broken, and the dyes of M and Y come out and mixed, so they are dyed to R. Therefore, using such a microcapsules can obtain a color image. It goes without saying that the present invention can be applied to output devices such as silver dye photographic films, toner development (described later in detail), and thermal transfer printers.

In addition, the display device is not limited to the CRT, and needless to say, the display device may be reproduced using a liquid crystal display, an electrochromic display, a projector, a light emitting diode display, an electroluminescent display, a plasma display, or the like.

Next, a method of correcting the phase potential of the information bearing medium will be described.

Fig. 27 is a diagram showing an embodiment in which a bright part (maximum exposure part) and an unexposed part are formed on the surface of the information bearing medium.

The bright part 151 is formed by the method as shown in FIG.

In Fig. 29A, a part of the electrode 7 of the photoconductor 1 is formed by bending, and is formed so as to be uniformly exposed on the surface of the photoconductive layer facing the information holding medium during exposure. As a result, a strong electric field is applied to the information holding medium, and electric charges are accumulated on the opposite information holding medium so as to obtain a maximum potential. FIG. 29 (b) is to thicken a part of the electrode so as to collectively expose the surface of the photoconductive layer, and the same effect as in the case of (a) is obtained.

Fig. 29 (c) forms a bright portion by irradiating the illumination light source 155 from the photosensitive member side.

The unexposed portion is formed in the manner as shown in FIG.

In FIG. 30 (a), the light shielding portion 157 is formed on the surface of the electrode support. In FIG. 30 (b), a part of the transparent electrode is formed of A1 to make it opaque so that debt does not pass. In FIG. 30 (c), a portion 161 of the photoconductive layer is formed in a part of the photoconductive layer so that no carrier is generated even when light is irradiated.

This non-photoconductive portion occurs in the same way as the photoconductive layer in the dark carrier where the carrier injection from the electrode is dark, and the transport characteristics of the injected carrier occur in the same way as the photoconductive layer in the dark state, and with respect to the wavelength of light to be exposed. Any material can be used if it is non-photoconductive. After all, even if it exposes, it may have any effect as long as it performs the same function as the photoconductive layer in an unexposed state. Examples of the material such as the use of PVK / TNF as a photoconductive layer and the use of PVK as a non-photoconductive part, in a functionally separated photosensitive member in which a charge generating layer and a charge transport layer are laminated, a charge generator is formed in a part of the charge generating layer. The non-conductive part is arrange | positioned by the part which is not contained, etc. are mentioned. Moreover, the insulating polymer material which adjusted the resistance value can also be used.

When the light and unexposed portions are formed in this manner, if the potentials are A and B, respectively, as shown in Fig. 28, the potential of the portion where the image is recorded takes the value therebetween. When the phase potential decreases due to the change over time, the potentials of the light and unexposed portions cancel out as well. Therefore, if the potential of the light and unexposed portions is measured in advance, the potential of the exposed portion can be easily corrected and obtained.

In addition, although the example which provided both the bright part and the unexposed part was shown in the said description, only one may be sufficient.

Fig. 31 shows a schematic structure of an embodiment of the information recording and reproducing processing apparatus of the present invention, in which the same numerals as in Fig. 1 denote the same contents, 171 is a photographing lens, 173 is a mirror, and 175 is a focus. Glass, 177 is pentaprism, 179 eyepiece, and 181 is negative.

The processing apparatus of the present invention uses the photosensitive member 1 and the information holding medium 3 shown in Figs. 1 to 3 instead of the film of the single-lens lef camera (however, in the case of the information holding medium of Fig. 2, the photosensitive member is unnecessary). When the power source 17 is turned on and off with a switch (not shown), the mirror 173 is popped up at a dotted line, and an electrostatic latent image of the subject is formed on the information bearing medium 3. In this case, the exposure may be performed by providing a mechanical shutter, or the exposure may be performed without providing a mechanical shutter because the photosensitive member plays an optical role as a shutter. If necessary, toner development of the information bearing medium results in a negative image 181. It is also possible to read the electrostatic potential, output it as an electrical signal, display it on a CRT, or transfer recording to another recording means such as a magnetic tape.

In addition, color imaging can be performed using a color filter.

32 is a view showing a color separation optical system by a prism, in which 191, 193, and 195 are prism blocks, 197, 199, and 201 are filters, and 203 and 205 are mirrors.

The color separation optical system consists of three prism blocks, and the light information incident on the a side of the prism block 191 is partially reflected on the b side, and is reflected on the a side to obtain the B color light component from the filter 197. Lose. The remaining light information enters the prism block 193, proceeds to the c plane, partly reflects off, and the rest goes straight to obtain G-color light components and R-color light components from the filters 199 and 201, respectively. The G, B color light components are reflected by the mirrors 203 and 205, so that the R, G, and B light can be obtained as parallel light.

By arranging such a filter on the front surface of the photosensitive member 1 as shown in FIG. 33, one-commer is performed by a set of R, G and B resolved information holding media 3 as shown in FIG. Alternatively, as shown in Fig. 33 (c), R, G, and B phases may be formed on one plane and set to one comer in parallel.

Fig. 34 shows an example of a fine color filter. For example, a film coated with a resist is exposed by a mask pattern to form R, G, and B stripe patterns, and formed by dyeing R, G, and B, respectively. Or a method of forming the hologram recording medium by storing the interference signals of R, G, and B generated by passing the color-decomposed light through thin slits, respectively, or the photoconductor. The masks are exposed in close contact with each other, and the R, G, and B stripe patterns are formed by electrostatic latent images, and the toner is developed by three rotations to form color to form a toner stripe. One pixel is formed with one set of R, G, and B of the film formed by such a method, and one pixel is made into fine about 10 micrometers. The color electrostatic latent image can be formed by using this filter as the filter 211 of FIG. In this case, the filter may be disposed away from the photoconductor or formed integrally with the photoconductor.

35 is a view showing an example in which a fine color filter and a Fresnel lens are combined. The Fresnel lens can reduce and record R, G, and B patterns, and is thinner and more compact than the conventional lens. Becomes possible, and mounting to the apparatus becomes easy.

The apparatus shown in Fig. 31 is a photosensitive member comprising a photoconductor layer having a transparent electrode disposed on the front surface instead of a photo film used in a conventional camera, and an information bearing medium formed of an insulating layer facing the photosensitive member and provided with an electrode on the rear surface. The electrostatic latent image of the incident image is formed on the information storage medium by applying a voltage to the positive electrode and making the photoconductive layer conductive according to the incident light and accumulating charge on the insulating layer according to the incident light amount. May be provided, but it is not necessary to install it, and the electrostatic latent image can be stored for a long time regardless of a bright place or a dark place.

Fig. 36 is a view for explaining an optical system used in the information recording and reproducing processing apparatus of the present invention. In the figure, 221 is an object, 223 is a first optical system, 225 is a color filter, 227 is a second optical system, and 1 is a photosensitive member.

36, the color filter 225 and the second optical system 227 are disposed on the entire surface of the photoconductor 1, and the image of the color filter 225 is imaged in the vicinity of the transparent electrode 7 of the photoconductor. It is.

First, an image of the object 221 is imaged on the color filter 225 by the first optical system 223. The color filter 225 is imaged on the transparent electrode 7 and strictly on the photoconductive layer by the second optical system 227. As a result of image exposure, the photoconductive layer 9 exhibits a conductive pattern corresponding to an image formed on the color filter 225, and an electrostatic latent image is recorded on an information bearing medium (not shown) corresponding to this pattern. As a result, spots and color spots on the image can be prevented.

37 shows another embodiment of the present invention.

In this example, the second optical system 227 is composed of a columnar lens array, a so-called cell width lens 231, which changes in a parabolic shape as the curvature is moved from the central axis to the outer circumference, and the cell width lens is formed of the photosensitive member 1. The color filter 225 is stacked on top of each other, with a transparent space having a predetermined thickness, for example, a glass substrate 233 interposed therebetween.

By such a configuration, the image of the color filter 225 can be formed in the vicinity of the transparent electrode 7, so that a high-resolution electrostatic latent image without color staining can be obtained.

As shown in Fig. 38, the cell width lens 231 has an object surface 241 and an image surface 243 in a symmetrical position with respect to the lens 231, and constitutes a lens system with a magnification of 1.

Therefore, in FIG. 37, the image of the color filter 225 can be formed at the position of the transparent electrode 7 by stacking the glass substrate 233 and the insulating layer 5 in the same thickness. By imaging the image, it is possible to record an image having high resolution and no color spots.

In addition, since the color filter and the photoconductor are disposed separately, this process can be manufactured in each process, thereby making it possible to prevent expensive color filters from being stretched or discolored by heat, thereby reducing the accuracy.

FIG. 39 is a diagram showing another embodiment of the present invention, and shows an example in which a cylindrical lens is used as the second optical system 227 of FIG.

The cylindrical lens has a lens system having power in one direction and no power in a direction perpendicular thereto, and therefore, a circular object as shown, for example, 251 is formed into an elliptical image 253. Therefore, when such a cylindrical lens is used as the second optical system, it is possible to perform image recording with a flattening function.

Although not shown, when a Fresnel lens is used as the second optical system, an image recording of a large image can be performed in a compact apparatus, and an image can be enlarged or reduced by using a convex lens, a concave mirror, or the like. It is possible to record.

40 is a diagram showing an embodiment of an information recording and reproducing processing apparatus using a photomultiplier tube. In the figure, 260 is an image intensity, 261 is an object, 263 is an objective lens, 265 is a photoelectric screen, 267 is an electronic lens, 269 is a multichannel plate (MCP), 271 is a fluorescent surface, and 273 is a switch.

The image intensifier 260 includes a photoelectric surface 265 for converting light into electrons, an electron lens 267 for forming electrons emitted from the photoelectric surface at a predetermined position, and an MCP 269 for amplifying incident electrons by several thousand times. ), A fluorescent surface 271 for converting the incident electron image from the MCP into an image of light is fitted in the vacuum tube bundle. At the rear of the fluorescent surface, a transparent substrate 5 having a transparent electrode 7 and a photoconductor 9 laminated thereon is combined.

In addition, the information holding medium 3 on which the electrode 13 and the insulating layer 11 are laminated on the substrate 15 is disposed on the photosensitive member 1 with a gap of about 10 μm interposed therebetween, and the transparent electrode 7 The battery E is connected between the electrode 13 and the electrode 13 via a switch 273.

In such a configuration, when an image of the subject 261 is formed on the photoelectric surface 265 via the objective lens 263, electrons are emitted from the photoelectric surface in correspondence to the incident light image. The emitted electrons are focused by the electron lens 267 to form an electron image on the incident surface side of the MCP 269. The MCP 269 is a thin glass plate having a diameter of 25 mm and a width of about 0.48 mm, and a thin hole of 12 μm, that is, the channel is opened innumerably, and when electrons enter the channel, it is attracted to the potential gradient in the MCP. Dozens of collisions on the inner wall are emitted to the other side.

In this collision, the wall of the channel emits secondary electrons, so the output electrons are multiplied thousands of times with respect to the incident electrons. The MCP has a total of 1.5 million channels, each of which corresponds to a pixel, and each school is multiplied at the same time.

The multiplied output electrons are attracted to the electric field and collide with the fluorescent surface to emit fluorescence. This fluorescence is brightened thousands of times more than the incident light amount, which is incident on the photoconductor 9 with the transparent substrate 5 and the transparent electrode 7 interposed therebetween. As a result, carriers are generated in the photoconductor 9 and the exposed portions exhibit conductivity. As a result, a strong electric field is applied in the gap between the information bearing medium in the conductive portion, and a corona discharge is generated, and charges corresponding to the incident light image are accumulated on the insulating layer 11.

Thus, the charge accumulated on the insulating layer is kept stable, so that the electrostatic latent image can be maintained for a long time. From time to time, the electrostatic latent image can be read by a method such as an optical reading using a toner phenomenon black or electric potential reading black or electro-optic effect. In addition, if the switch 273 is not turned on, an image is not formed on the information holding medium, so that the switch 273 can be provided with a shutter function.

In addition, in the above embodiment, the transparent electrode and the photoconductor are laminated on the fluorescent surface with the transparent substrate interposed therebetween. However, since the transparent substrate interferes with the high resolution on the thick substrate, the transparent electrode is directly formed on the fluorescent surface and the luminous intensity is formed thereon. The whole may be laminated.

Alternatively, a mechanical shutter may be provided on the front surface of the photoelectric surface instead of the voltage shutter by the switch, and black may vary the distance between the photoconductor and the information holding medium, and be placed near the critical distance where corona discharge occurs. You may have a shutter function by changing a distance. In addition, in the above embodiment, an example of using an image intensifier has been described, but the wavelength range of incident light is infrared rays or ultraviolet rays, and it may be used in combination with an image converter that photographs such an invisible image and converts it into a visible image. Not to mention.

41 is a diagram showing an embodiment of a cassette for an information recording and reproducing processing apparatus. In the figure, 280 is a cassette, 281 is a window, 282 is a bar code, 283 is a photosensitive member, 285 is a film-like information holding medium, 287 is a film supporting agent, 289 is a supply roll, and 291 is a winding roll.

The cassette 280 is an integral case made of plastic or the like. In this embodiment, a flexible film is used as the information bearing medium. A window 281 is opened on the upper surface of the cassette, and a photosensitive member 283 is fixed to the cassette case at that portion. An interval setting member 287 having a smooth surface facing the photosensitive member 283 at a predetermined interval is provided, and is fixed to the cassette case while keeping the interval between the photosensitive member and the information holding medium constant. By doing this, the distance between the photosensitive member and the information holding medium can be set to a predetermined precision. In addition, the interval setting member 287 may be positioned so as to change the distance between the photosensitive member and the information holding medium. In addition, since the sensitivity varies depending on the type of material of the photoconductor, information such as the photoconductor material is displayed as the conductive bar code 282, for example, to be read by a contact point provided in the camera. And the film-form information holding medium 285 which contact | connected the smooth surface of the space setting member 287 was unwound from the supply roll 289, and it is wound up by the winding roll 291 that recording was complete | finished.

In this case, the film as the photosensitive member and the information bearing medium is already set in the cassette, and the subtle spacing between the two is adjusted at the time of insertion, so that the user can prepare a cassette for the type of photosensitive member according to the purpose. The cassette into which the desired photosensitive member is inserted can be selected, and the cassette of the sensitivity according to the objective can be selected like ASA100 and ASA500. In the present embodiment, one window is provided and the recording is performed through this window.

When the cassette is inserted, the contact 307 contacts the barcode 282 and reads the material of the photoconductor inserted into the cassette, and accordingly The ROM built in the device 309 automatically sets shooting conditions such as an applied voltage, a shutter speed, and an aperture between the photosensitive member and the information holding medium. Therefore, the user can easily perform high-resolution shooting by performing image exposure under optimum and conditions by simply turning on a switch (not shown).

FIG. 43 is a view showing another embodiment of the electrostatic lock cassette, and the same numerals as in FIG. 41 denote the same contents. 311 and 313 are spacers, 315 and 317 are rolls, and 319 and 321 are springs.

What is necessary is just to take earth through a roll in a present Example.

FIG. 44 shows a disc type electrostatic lock cassette, and FIG. 45 shows an information recording and reproducing apparatus in which the cassette of FIG. 44 is inserted. In the figure, 330 is a disc type cassette, 331 is a case, 333 is a photosensitive member, 335 is an information bearing medium, 337 is a spacer, 339 is a window, 341 is a hole of a cassette, 343 is a hole of a disc, 350 is a camera, and 351 is an object The lens 353 is an aperture, 355 is a shutter, 357 is a rotating shaft, and 359 is a rotary knob.

In this embodiment, the information holding medium is a disk type, and a disk-shaped disk is inserted into the cassette 330. A window 339 is opened in the case 331, and image recording is performed therethrough. A hole 341 is opened in the center of the case, and a hole 343 is opened in the center of the disk. The cassette is set in the camera 350, the rotating shaft 357 passes through the holes 341 and 343, and the rotary knob 359 is rotated to rotate the disk, and the predetermined information is retained through the objective lens 351. Image recording can be performed on the medium portion.

46 is a view showing an embodiment of an information recording and reproducing processing apparatus having a voice information input function, in which 371 is a microphone, 372 is an amplifier, 373 is a laser, 374 is an acoustic optical modulator, 375 is a polygon mirror, 376 is the power source.

The optical body 1 is such that a predetermined voltage is applied from the power supply by the on / off of the switch between the information holding medium 3. Subsequently, surface exposure is performed by the image information light 370 while a predetermined voltage is applied to the information holding medium 3 to form a latent image potential corresponding to the image. Usually, the electric signal is amplified by the amplifier 372 according to the voice with the microphone 371 interposed therebetween, and the acoustic optical modulator 374 modulates the laser light from the laser 373 according to the voice signal, and the polygon mirror 375. ), The photoconductor 1 is irradiated, and a potential is formed on the information bearing medium 3 in accordance with an audio signal. Thus, the information holding medium 3 records the audio information together with the image information. As a result, for example, when recording an image such as a landscape on an information bearing medium, the situation at the time of shooting and the like can be recorded as audio, and when reproducing, it is possible to obtain a reproduced image containing the description at that time.

In the above description, the optical modulator and the polygon mirror are combined to modulate the debt so as to scan exposure. In addition, for example, the electron beam is scanned by combining the CRT and the changing means such as a flying spot scanner (FSS). Scanning exposure may be carried out through the photoconductor by light from the bright spot of the CRT surface, and an information bearing medium is placed close to the CRT type having a sedimentation electrode group at the conduit portion, and a scanning electron beam is disposed through the deposition electrode. The discharge recording may be performed directly on the information bearing medium.

FIG. 47 is a diagram showing another embodiment of the present invention using PCM modulation, in which the same numbers as in FIG. 46 denote the same contents. In the case of Fig. 47, since the voice signal is converted into a digital signal by the PCM 380, it is possible to record high quality voice information resistant to noise.

48 is a view showing another embodiment of the present invention, in which 381 is an A / D converter, 382 is a cyclic memory, and 383 is a D / A converter.

In this embodiment, the audio signal is A / D changed and stored in the circular memory 382, and the output of the circular memory 382 is D / A converted to record this. The circular memory 382 has a storage capacity that records the voice information for a predetermined time, and updates the recorded contents sequentially so that the voice information from a certain time before now is stored. For example, if the memory capacity of the circular memory can be recorded for 1 minute of audio information, the audio information can be recorded from 30 seconds to 30 seconds before the point of shooting. It becomes possible. For example, in the shooting of an SL, if the SL image can be taken together with the sound of a chic waterfall, a chic waterfall, and a shutter sound, the reproduced image can be expected to remind the situation at the time of shooting very similarly.

FIG. 49 shows an embodiment of the information recording and reproducing processing method, wherein the same numerals as in FIG. 1 denote the same contents. 391 is a dielectric.

In this embodiment, an electrostatic latent image is formed on the insulating layer 11 with a dielectric 391 interposed between the photosensitive member 1 and the information bearing medium 3 with a dielectric agent interposed therebetween. Since the dielectric 391 is present, the insulation breakdown voltage can be improved and the supply voltage of the power supply 17 can be increased. Therefore, it is possible to apply a high voltage between the photosensitive member and the information holding medium, even if there is a slight light incident. It is possible to form a latent image on the holding medium, which can dramatically improve the sensitivity. When a sufficiently large voltage is applied, the generation efficiency of the carrier when light is irradiated can be close to one.

As the dielectric 391, it is possible to use a solid inorganic insulating material or a solid organic insulating material as mentioned below as the solid insulator.

Fig. 50 (b) shows the position of the photosensitive member or the information holding medium as a window, and the other parts are the same as those in Fig. 50 (a).

Thus, by interposing an insulating material between the photosensitive member and the information bearing medium, spark discharge can be prevented from occurring even when a high voltage is applied, so that the carrier generation efficiency upon exposure can be increased by increasing the applied voltage. High sensitivity voltage application exposure can be achieved.

Fig. 51 is a diagram showing one embodiment of an information recording and reproducing processing method.

As shown in Fig. 51A, a predetermined voltage is applied between the photosensitive member 1 and the information holding medium 3 by the power supply 17, and the information holding medium 3 is exposed in this state. Negative charge is trapped on the insulating layer 11 and the latent image is formed. To erase this latent image, as shown in FIG. 51 (b), the polarity of the power source 17 is reverse polarity, and when exposed in the exposure pattern as shown in FIG. 51 (a), the insulating layer 11 of the information bearing medium 3 (A) and a reverse polarity current are recorded thereon, so that the latent image formed by the exposure shown in FIG. 51 (a) is canceled, so that the potential on the insulating layer 11 is zero and the latent image is removed. .

As shown in Fig. 51 (c), when the light having the same polarity as that of the exposure of Fig. 51 (a) is applied and the exposure is performed in a pattern opposite to that of Fig. 51 (a), negative charge is formed on the insulating layer 11. Becomes uniformly charged and the latent image is erased. In the case of Fig. 51 (c), since the insulating layer 11 is maintained at a predetermined constant potential, writing is possible by exposing the polarity of the power supply voltage in reverse.

FIG. 52 is a diagram showing another embodiment of the present invention in which the latent image is erased by uniform exposure to the information bearing medium having the latent image formed thereon.

Fig. 52 (a) shows an example in which uniform exposure is applied by applying a voltage having the same polarity as in voltage-applied exposure, and the portion where the latent image is formed is charged again by exposure, so that the exposure is saturated quickly. The charge amount placed on the portion is saturated by continuing the exposure of the portion where the latent image is not formed again. Thus, the surface of the insulating image 11 reaches the saturation voltage by performing exposure for a predetermined time, and the latent image is erased. In this state, the exposure voltage can be rewritten by exposing the power supply voltage to reverse polarity.

Fig. 52 (b) shows an example in which uniform exposure is performed by the applied voltage of reverse polarity and the exposure time in Fig. 52 (a). In this case, the portion not exposed in Fig. 51 (a) is first charged with a positive charge. After saturation, the portion exposed to the latent image is saturated, and the entire surface is uniformly charged, and the latent image is erased. In this case as well, the voltage can be reversed and rewritten.

Fig. 52 (c) shows an example of latent image erasing only by applying a voltage. The photosensitive member has a high resistance and a slow erasing speed in a state in which light is not irradiated, but in this erasing method, uniform illumination is not required. It is also possible to increase the erase speed by using an electrode instead of the photoconductor. In the drawing, a voltage having a different polarity than that at the time of recording is applied, but of course, a voltage having the same polarity as at the time of recording may be applied.

Fig. 53 is a view showing an embodiment in which uniform charging and latent image erasing are performed by corona discharge.

In this embodiment, for example, AC corona discharge is performed, and the latent image is erased by uniformly charging the insulating layer 11 by electrostatic charge or negative charge. Of course, it is also possible to discharge by direct current, not by alternating current.

54 to 57 show a latent image erasing method by heating.

Fig. 54 is a view showing a method of erasing a latent image by infrared heating. The insulating layer 11 is heated by irradiating infrared rays to the information bearing medium having the latent image, and as a result, the conductivity of the insulating layer 11 is reduced. As a result, the charge that forms the latent image leaks and the latent image is erased.

Fig. 55 is a view showing an embodiment in which latent image erasing is performed by resistance heating while energizing an electrode of the information holding medium. The electrode of the information bearing medium is formed of a material having a resistance of 106 kPa · cm or less, and has a predetermined resistance, so that heat is generated by energizing it, and the information holding medium itself is extremely thin and has a small heat capacity. As a result, the charges forming the latent image leak and erase the latent image.

Fig. 56 shows the latent image erasing by microwave heating. The dielectric layer of the insulating layer 11 generates heat, the temperature rises, the conductivity increases, the charge leaks, and the latent image is erased.

57 shows an example of erasing a latent image by heating the surface of the insulating layer 11 of the information bearing medium using the thermal head. The thermal head 401 is heated and the insulating layer 11 is in contact or non-contact. The latent image is erased by leaking a charge that forms a latent image.

58 is a view showing an embodiment of erasing a latent image by irradiating ultraviolet rays.

Fig. 58 (a) shows an example of irradiating ultraviolet light with a pattern similar to that of an exposure pattern on which a latent image is formed, whereby electrons and electron carriers are generated in the insulating worms 11 by irradiation of ultraviolet rays, and a latent image is formed. Since the electric field is generated by the charge forming the latent image, the charge and the reverse polarity carriers stick together to be neutralized, and the opposite polarity charge flows to the earth side. As a result, the charges forming the latent image are neutralized and the latent image is erased.

Fig. 58 (b) shows an example in which ultraviolet rays are irradiated onto the information bearing medium collectively. The portion where the latent image is formed is neutralized as in Fig. 11 (a), and the other portion is generated because no electric field is generated. Since the carrier immediately recombines and disappears, the electric charge is not accumulated on the insulation 11 as a whole, and the latent image can be erased.

Fig. 59 is a view showing an embodiment in which the electric charge on the insulating layer 11 is leaked by the current collecting member. In the figure, 403 is a conductive member, and has a brush 405, so that the latent image can be erased by leaking electric charges by scanning the surface of the information holding medium with the brush 405.

Fig. 60 is a view showing an example in which water vapor is sprayed onto the information bearing medium to impart conductivity to leak charge, and the charge leaks through the conductive gas to remove the latent image.

As described above, since the latent flaw on the information holding medium having high insulation and difficult to erase can be erased very simply or reliably, the information holding medium can be repeatedly used.

Next, an example of an information recording and reproducing processing apparatus using the information holding medium of the present invention as an external storage device will be described.

FIG. 61 is a view showing an embodiment of an image processing system using an information holding medium as a recording medium, in which 3 is an information holding medium, 411 is a reading head, 412 is an A / D converter, 413 is a computer, and 415 is a drawing. A magnetic disk, 416 is a magnetic tape (MT), 417 is a D / A converter, 418 is a printer, 419 is a recording head, 420 is a recording cylinder, and 421 is a film.

In the figure, a predetermined original is recorded on the information holding medium 3. The read head 411 scans the surface of the information bearing medium 3 to read the electric potential in the same manner as described later, A / D conversion, and reads it into the computer 413. In this case, the image data is enormous, and in order to read a lot of image information, the image data is recorded on the magnetic disk 415 or the magnetic tape 416. Image synthesis, color correction, and magnification conversion while reading this when necessary and observing it on a monitor not shown. Predetermined image processing, such as masking and detail enhancement, is applied to the film 421 set in the recording cylinder 420 through the recording head 419. The image data can be printed out by the printer 418 as necessary.

In this case, since the information holding medium 3 constituting the input scanner is a flat head type, it does not require a cylinder or the like to read out, and can be made compact in size, and no troublesome operation such as a set of originals is required. In addition, analog information is recorded on the information holding medium (3) by surface exposure. However, the time required for recording and reading out of the MT can be omitted by using the MT as it is. Can shorten the overall time.

FIG. 62 is a diagram showing the overall configuration of an information recording and reproducing processing apparatus using the information holding medium of the present invention, wherein the same numerals as those in FIG. 61 denote the same contents. 430 is a reading cylinder, 431 is a reading head, 432 is a manuscript, 441 is a laser, 442 is a D / A converter, 443 is an optical modulator, and 444 is a polygon mirror.

In the apparatus shown in Fig. 62, the document is read and the exposure recording is the same as that of a conventional scanner, but the information holding medium is used instead of the MT which stores the read image data once. That is, the image data read into the computer 413 is converted into analog information by the D / A converter, modulates the laser light from the laser 441 with this signal, and irradiates the linear photoreceptor 1 with the polygon mirror 444. By doing so, the information holding medium 3 is sequentially recorded. The information thus recorded is optionally read at the desired time by the potential reading head 411 as in the case of Fig. 61, A / D converted, put into a computer, and the film 421 through the image-processed recording head 419. ).

According to this system, since the information holding medium is used as the recording medium of the image data, the time required for downsizing, reading out, and recording the device can be shortened, and the recording can be permanently stored.

In addition, in the above description, the light is modulated by the combination of the optical modulator and the polygon mirror to scan exposure. In addition, for example, the electron beam is scanned by the combination of the CRT and the deflection means such as a flying spot scanner (FSS), and the CRT The light from the surface bright spot may be scanned and exposed through a photosensitive member. In addition, the information holding medium may be disposed to face the surface of a kind of CRT having a sedimentary electrode group at the convex part, and the discharge electrode may be directly discharged and recorded on the information holding medium via the precipitation electron beam. It is also possible to use a semiconductor laser as a laser. In this case, a method of directly modulating a semiconductor laser without using AOM (acousto-optic modulator) shown in the drawing is common.

63 and 64, a method of recording color image information will be described.

In FIG. 63, the document 453 is irradiated with a light source 451 or a light source 452, and the reflected or transmitted light is interposed between the photosensitive member 1 with the color filter 455 interposed therebetween. Record in 3). The color film 455 has three elements, R, G, and B. The color film 455 is moved horizontally to select R, G, and B, and the recording of one piece of image information is completed with one set of three information holding media. .

In FIG. 64, the color film 456 is made into a rotary type, and it is the same as the case of FIG. 63 except that R, G, and B are selected by this rotation.

Next, the characteristics of the case where the information holding medium of the present invention is applied to the scanner system will be described with reference to FIGS. 65 to 69. FIG.

Fig. 65 shows the phase potential change characteristic with respect to the exposure amount of the information bearing medium of the present invention, and the exposure amount is in logarithmic scale in arbitrary units.

In the plate making scanner, the dynamic range of the phase concentration (the logarithm of the ratio of the transmitted light to the irradiated light) is usually about 3 ranges. Currently, this is achieved by using a photomultiplier. There is only a dynamic range of degree and cannot be used for engraving. On the other hand, in the information bearing medium of the present invention, as shown in the characteristic shown in Fig. 65, the phase potential changes substantially linearly in response to the change of the three digits of the exposure amount, so that it can sufficiently cope with the dynamic range of the three degrees of performance. It can be seen that it is the most suitable for the plate making scanner.

Fig. 66 is a view showing the case of rotating the original by a predetermined angle.

In the case of conventionally rotating and exposing an image, the calculation process is very simple when it is calculated by a computer. Therefore, the original is rotated by a predetermined angle in the drum scanner's reading cylinder so that the original is rotated by a predetermined angle. The work to set was very great. Since the information holding medium of the present invention is flat, as shown in FIG. 66, the information holding medium 3 can be easily and accurately rotated by a predetermined angle as shown in 3a, and the image holding medium can be easily read by sequentially reading as shown in the slaughter table of the figure. You can rotate In the rotation, the center of the image is usually the rotation center, but in the illustrated example, the angle of the upper left is the rotation center. The center of rotation is image processing if the center of the table on which the information bearing medium is placed and the rotational relationship of the image on the information holding medium are subjected to image processing, thereby obtaining a desired rotating image. In addition, by changing the rotation speed or the like, a special deformed image is also obtained.

67 is a diagram illustrating a case where a predetermined image is cut out from an original.

Conventionally, for example, when the figure 461 is to be cut out, the original is largely cut out by the mask on the soft surface as shown by the dotted line 463 in the drawing. However, in the case of the information bearing medium of the present invention, the figure 461 is used. Only the figure 461 can be read easily by using the mask of the shape of the same shape.

Fig. 68 is a view showing an operation of cutting out an original.

For example, in the drawing, if the image to be cropped is 471 and the clipping instruction is 472, the relative position relationship with the position of the head 411a from the origin of 472 is detected by the detection circuit 475, and the detection is performed. By driving the XY stage 476 by a signal, the information holding medium can be moved to read only the indicated area or to leave the information of only the indicated area and erase the rest.

69 is a diagram for explaining sharpness processing.

First, in FIG. 69 (a), an image 481 whose density increases in steps is recorded. Next, in FIG. 69 (b), the polarity of the voltage applied to the information holding medium is reversed, and an unsharp signal 482 is separately obtained by means such as passing a signal of the image 481 through a loafers filter. Double exposure is performed on the electrostatic latent image at 481. In this case, since the reverse polarity voltage is applied in the exposure, calculation of the images 481 and 482 is performed, resulting in the electrostatic latent image as shown in 483 of the figure. In FIG. 69 (c), an image of which edge is emphasized is obtained by overlapping and exposing the original image 481 on the image 483, which is applied with the same voltage as in the case of FIG. 69 (a). The sharpening process can be performed simply by repeating surface exposure.

This sharpness process is performed by the addition and subtraction of the phase potential, and when this is developed, the two-dimensional image operation sound can be rinsed by the information holding medium.

The formation of the negative latent image in the present invention can be obtained simply by exposing the same amount of light with a bias of a predetermined polarity and then exposing it with a reverse polarity voltage.

70A and 70B show an embodiment of an information recording and reproducing processing apparatus for the purpose of protecting a printed document. 1, information holding medium, 500 camera, 501 color separation filter, 7 photosensitive member, 503 document, 511 reading head, 513 amplifier, 515 signal processing device, 517 memory, 519 CRT, 521 Is an input device, and 523 is a recording head.

In Fig. 70 (a), the printed document 503 is read out by the electrostatic camera 500. The electrostatic camera 500 includes a color separation filter 501, a photosensitive member 7, and an information holding medium 1, and the color separation filter 501 decomposes an input image into R, G, and B images. A predetermined voltage is applied between the photosensitive member 7 and the information holding medium 1, and the photosensitive member 7 exhibits conductivity at the portion to which light is irradiated by exposure, and at the portion between the photosensitive member 7 and the information holding medium. The discharge is generated, and as a result, an electrostatic latent image is formed on the information bearing medium 1 in accordance with the image.

Next, in the signal processing apparatus 515 of FIG. 70 (b), predetermined image processing is performed, and the color image is displayed on the CRT 519. FIG. In the planning information section, the input device 521 inputs, as data, the designation of the black portion or the enlargement magnification of the portion while trimming while viewing the color image. Color image and plan information data in the signal processing device 515 are electrostatically locked onto the information holding medium 1 via the recording head 523.

Fig. 71 shows an information retaining body recording a color image and planning information, A is a printed original image, and B is an acquired electrostatic image of the planning information. Thus, by recording the printed document and the planning information of the information holding medium and sending it to the printing process in the printed document, it is possible to completely prevent damage or contamination of the printed document conventionally generated in each court.

In addition, in the case of recording from the signal processing device 515 to the information holding medium 1 by the recording head 523 in Fig. 70 (b), the recording head is scanned on the information holding medium to perform electrostatic lock. There is a method of optically modulating the laser light at the output from the processing apparatus 515, and applying a voltage applied exposure to the information bearing medium while scanning the modulated laser light, and an ion deposition method.

FIG. 72 is a view showing an ion deposition method, in which a corona discharge is generated between the information holding medium 1 and the electrode 541, and a gate electrode insulated from the electrode 541 and the insulator 547 (Fig. A predetermined voltage is applied to 545, and the voltage control controls the corona 543 to adhere to the information holding medium to form an electrostatic latent image.

In this way, the information holding medium is used instead of the printed documents such as color originals, thereby preventing damage to the originals, and setting the planning information while viewing the display on a CRT or the like. Since the information and the manuscript information are recorded on the same medium, it is possible to reliably prevent the wrong printing process by changing the manuscript and the planning information.

Fig. 73 is a diagram showing the overall configuration of the color scanner of the present invention, wherein the same numerals as those in Fig. 70 are the same. 522 is a printer and 529 is a cylinder.

In FIG. 73, the information bearing medium 1 is arranged opposite to the photosensitive member, and the electrostatic latent image is recorded by exposing the photosensitive medium to a state in which a predetermined voltage is applied.

The information holding medium 1 also records planning information B such as designation of enlargement magnification or trimming other than the original image A as shown in FIG. For example, the planning information is recorded by the head 511 which reads out the electrostatic latent image of the information holding medium 1 in Fig. 73, and subjected to image processing by the signal processing device 515 to perform the CRT 519. Color image is displayed on the screen, and the magnification or trimming specified data is inputted by the input device 521 while viewing the color image, and the laser beam is optically modulated by the output from the signal processing device 515 to apply voltage. The method or the ion deposition method can be used to record the information on the medium.

Next, looking at the color image displayed on the CRT 519, the highlight point H and the shadow point S are determined as shown in FIG. At the same time, it is determined whether or not the distance between H and S is set to an output concentration of a characteristic such as P or Q in the figure. Thus, when the setup is completed, for example, a hard copy is printed by the sublimation transfer printer 15, and a check is made to see if the set is appropriate. When setup is complete. The signal processing device 515 outputs the printed image to the plate making film set on the cylinder 529 with the recording head 523 interposed therebetween.

75, the print processing step will be described in more detail.

First, the reading device 531 reads out the electrostatic latent image recorded on the information holding medium. This is read out by the head 511 which reads out the latent electrostatic image recorded on the information holding medium 91. The analog data read out is increased or decreased by the amplifier 513, and then digitally converted, and color correction is performed by the color correction unit 533. FIG. Color correction first converts the R, G, and B signals into C, M, Y, and K signals in the color conversion unit 533a. Next, since the ink has residue, the residue correction to the C ', M', Y ', and K' is performed by the residue correction unit 533b.

Next, the above-described setup is performed and the halftone process 535 is performed. When the halftone is formed, the exposure process 537 is performed accordingly.

For example, as shown in Fig. 76, the size of the dot is changed according to the image density. If it feels white, it is shown in Fig. 76 (a). 50% halftone as shown in FIG. 76 and a black dot as shown in FIG. 76 (c) when it feels black. In this manner, the size of the dot is changed with respect to the image density without changing the pitch of the dot.

For example, as shown in Fig. 77, the dot dots may be formed by a dot generator.

The method is outlined. When one half point is shown in Fig. 77 (a), it is superimposed as shown in the drawing, and the density level of the image corresponding to one half point is 8 as shown in Fig. 77 (b). Then, the superimposed value is compared with the level 8 of the image, and the portion where the superimposed value exceeds the density level is made black as shown in Fig. 77 (c). In this way, a dot dot of size can be formed according to the concentration level.

In this way, since the information holding medium is used as the color document glass, it is unnecessary to hold the front end of the scanner without damaging the color document, thereby improving work efficiency. In addition, since the planning information is mechanically read from the information holding medium recorded with the image, it is possible to make the mistake. In the case of the conventional magnification, if the magnification is incorrect, it is necessary to use a drum that is incorrectly used. However, in the present invention, the magnification can be changed only by changing the scanning density to be read.

Fig. 78 is a diagram showing one embodiment of an information recording and reproducing processing method for the purpose of original copying. In the figure, 540 is a disc, 541 is an electrode, 543 is a pattern layer, 543a is an insulating part, 543b is a conductive part, 2 is an information carrier, 11 is an insulating layer, 13 is an electrode, 15 is a support, 17 is a DC power supply, S Is a switch.

The disc 540 has an insulating portion 543a formed on the electrode 541, which is in contact or non-contact with the information bearing medium 3 on which the electrode 13 and the insulating layer 11 are formed on the support 15. And a direct current voltage is applied by the power supply 17 between the electrode 13 and the electrode 541. Discharge occurs between the conductive portion 543b and the insulating layer 11 by the application of a voltage, and an electrostatic latent image corresponding to the pattern of the conductive portion 543b is formed on the insulating layer 11 to form a pattern of the original plate 540. It can be duplicated on the information bearing medium (2). The duplicated pattern may be read out electrically and displayed on a CRT or the like to form a toner.

Next, the material of the information holding medium and the working method of the information holding medium will be described.

Since the information holding medium 2 records the information on the surface black of the insulating layer 11 in a distribution of electrostatic charge therein, the information holding medium itself is used as the recording medium. Thus, by the recorded information or the method of recording, the shape of the information bearing medium can take various vane shapes. For example, it may also be a general film (for shorter or continuouser), disk, tape or circular shape.

Insulating layer support 15 is to support the information holding medium as described above, specifically, when the information holding medium is a flexible film, tape, disk shape, flexible plastic film or metal sheet Etc. are used, and when strength is required, inorganic materials such as rigid sheets, glass, or organic materials such as rigid sheets, and the like are used.

The electrode 13 of the information holding medium is formed on the insulating layer support l5.

Since the insulating layer 11 records information in the vicinity of the surface or inside thereof as a distribution of electrostatic charges, it is required to have high insulating property in order to suppress the movement of electric charges, and to have an insulating property of 10 ¹⁴ Ω · cm or more as a specific resistance. do. The insulating worms 11 may be formed by dissolving or heat-melting resins, rubbers, and the like in a solvent and coating, dicing, or forming a layer by vapor deposition, sputtering, or CVD.

Here, as the resin and rubber, for example, polyethylene, polypropylene, vinyl resin, styrol resin, acrylic resin, nylon 66, nylon 6, polycarbonate, acetal homopolymer, fluorine resin, cellulose resin, phenol resin, glass sub resin, poly Ester resins, epoxy resins, flexible epoxy resins, melamine resins, silicone resins. Phenoxy resin, aromatic polyimide, PPO, polysulfone, etc., polyisoprene, polybutadiene, polychloroprene, isobutylene, ultra high nitrile, polyacryl rubber, chloro sulfonated polyethylene, ethylene propylene rubber, fluorine rubber, silicone A single body or a mixture of rubber such as rubber, polysulfide synthetic rubber and urethane rubber is used.

In addition, a silicon film, a polyester film, a polyimide film, a fluorine-containing film, a polyethylene film, a polypropylene film, a polyparabanic acid film, a polycarbonate film, a polyamide film, or the like is placed on the information bearing electrode 22 with an adhesive or the like. The layer may be formed by adhering to a layer, or may be formed by coating and dipping a curing agent, a solvent, or the like necessary for a thermoplastic resin, a thermosetting resin, an ultraviolet curable resin, an electron beam curable resin, a rubber, or the like.

In addition, as the insulating layer 11, a monomolecular film or a monomolecular film formed by the Lenmuir project method can also be used.

In addition, the insulating layer 11 can be provided with a charge holding enhancement layer between the electrode surface or on the insulating layer 11. The charge-bearing enhancement layer is a layer in which charge is injected when a strong electric field (104 V / cm or more) is applied, but no charge is injected in a low electric field (104 V / cm or less). As the charge holding reinforcing layer, for example, SiO ₂ , Al ₂ O ₃ , SiC, SiN, or the like can be used. As the organic material, for example, a polyethylene deposition film or a polyparaxylene deposition film can be used.

In order to maintain the electrostatic charge more stably, the insulating layer 21 may be impregnated with a material having an electron donor (donor material) or a material having an electron acceptability (acceptor material). As donor materials, there are styrene-based, pyrene-based, naphthalene-based, anthracene-based, pyridine-based and adine-based compounds, specifically, tetrathioflubarene (TTF), polyvinylpyridine, polyvinylnaphthalene, polyvinylanthracene, polyadine, Polyvinylpyrene, polystyrene, etc. are used and it uses one kind or it mixes. In addition, as the acceptor material, there are halogen compounds, cyan compounds, nitro compounds, and the like. Specifically, tetracyanoquinomethane (TCNQ), trinitrofluorenone (TNF), and the like are used. Donor material and acceptor material are used by adding about 0.001-10% with respect to resin.

Further, in order to keep the charge stable, fine particles can be added to the information bearing medium. Examples of the particulate material include periodic table group IA (alkali metal), copper IB (cognate), copper IIA (alkaline earth metal), copper IIB (zinc group), copper IIIA (aluminum group), copper IIIB (rare earth), As the Group IVB (Titan), Group VB (Vanadium), Group VIB (Chrom), Group VVII (Manganese), Group VIII (Iron, Platinum), and Group IV IV (Carbon) As germanium, silver, lead, copper VA group (nitrogen group), antimony, bismuth, copper VIA group (oxygen), sulfur, serene, tellurium are used as microparticles. Metals in the above materials may also be used in the form of metal ions, finely divided alloys, organometallics, and complexes. In addition, the elemental groups may be used in the form of oxides, phosphates, sulfur oxides, halides. These additives may be added in a very small amount to the information holding medium such as the resin or the rubber described above, and the amount of addition may be about 0.01-10% by weight relative to the information holding medium.

The insulating layer 21 needs to have a thickness of at least 1000 kPa (0.1 µm) or more in terms of insulating properties, and preferably 100 µm or less in terms of flexibility.

The insulating layer 11 formed in this way can be provided with a protective film on its surface in order to prevent breakage or discharge of information charges on the surface thereof. As a protective film, rubber | gum, such as adhesive silicone rubber, resin, such as polyterpene resin, may be made into a film form, and it may adhere | attach on the surface of the insulating layer 21, or a plastic film may be adhere | attached using an adhesive agent, such as a silicone oil. The resistivity may be 10 ¹⁴ Pa · cm or more, the film thickness is about 0.5-30 µm, and the thinner the protective film is, the better the thickness of the insulating layer 11 needs to be. When the information is reproduced, the protective layer may reproduce information on the protective film, or the protective layer may be peeled off to reproduce the information of the insulating layer.

Next, a method of producing the original will be described with reference to FIGS. 79 to 83.

79 shows an example in which an insulating pattern is formed on an electrode substrate. An electrode 541 is formed on the support 545, and an insulating pattern 547 is formed on the electrode 541. When the original plate is used, discharge occurs between the portion where the insulating pattern of the electrode 541 is not formed and the information holding medium, thereby replicating the original plate.

Fig. 79 (b) shows an example in which a patterned electrode is provided on the surface of the support having at least the surface of the insulating film. In the case where the support is self-insulating such as glass, for example, a direct electrode may be provided on the glass.

79 (c) shows an example for making electrical contact with the isolated electrode without changing the pattern. In this example, a defective portion is partially formed in an insulator located at an isolated electrode of the surface insulating layer of the conductive support, and electrical contact is made to the isolated electrode through the conductive support.

80 is a diagram illustrating an example in which a conductive pattern is formed by passing a conductor through an insulating material.

The conductor 552 is embedded through the insulator 551, and the face of the insulator and the conductor is faced on the surface side facing the information holding medium, and the conductor portion protruding from the insulator on the opposite side is connected to the wiring 553. Connect and apply voltage.

As a method of embedding the conductor 552 in the insulating material 551, for example, a thin insulating film is used as the insulating material 551, which is formed on a metal plate, and is formed by patterning a thin pin-shaped conductor. In addition, if the resistance value of the pin is changed according to the place, a dark image can be obtained.

81 and 82 form a recess 561 in the conductor, so that no discharge occurs in the recess 562, and as a result, the pattern can be duplicated. 82, the insulating material 563 may be embedded in the recess 562 by skidding.

83 is a view showing an example in which a pattern is formed by overexposure using a photoconductor (hereinafter, referred to as a memory photoconductor) that exhibits persistent conductivity by exposure, in a medium having a photoconductive insulating layer formed on an electrode substrate.

An ITO electrode 572 is formed on the glass substrate 571, and an insulating film 573 is formed thereon. The insulation 557 uses polyvinylcarbazole (PVK), for example, and when it irradiates with ultraviolet light, the resistance value of the part becomes low, and it shows electroconductivity, and the counterpart is hold | maintained for several hours. Then, when heat is applied, the film is returned to the insulator and, for example, it is almost returned to the insulator at about 150 ° C. for about 1 second. Therefore, it can be set as the window plate in which the conductive pattern was formed by exposure, and the heated pattern can be erased and it can be used repeatedly after that.

In addition, for example, when triphenylmethane dye is added to PVK, a continuous conductive pattern can be formed even by visible light, and a He-Ne laser can also be used. In addition, the luminance of the light source to be exposed may be made constant, and a pattern may be formed with or without exposure, or the luminance of the exposure light source may be spatially modulated to be changed to obtain a dark image.

Fig. 84 is a diagram showing an example in which an insulating film is used as an information bearing medium and continuous copying is performed. 581 is a cylindrical disk, 582 is a cylindrical electrode, 583 is a DC power supply, 584 is an insulating film, 585 is a developing device, 586 is a fixing device, 587 is a supply roll, and 588 is a winding roll.

79-83, the cylindrical cylindrical surface 581 is created, the cylindrical electrode 582 is opposed to this, and the insulating film 584 is continuously contacted with the cylindrical electrode 582 in contact. To supply. The cylindrical disk 581 and the cylindrical electrode 582 are rotated at high speed to form an electrostatic latent image on the insulating film, and the formed electrostatic latent image is toner-shaped by the developing device 585 and the counter electrode 585 ', and the fixing device ( By depositing at 586, the original can be replicated at a very high speed. In addition, although a cylindrical disk and a cylindrical electrode show noncontact, you may make it contact.

85 is a diagram showing an example of transferring the toner image formed on the insulating film 584 of FIG. 84 to the transfer paper 591. As described above, the toner image formed on the insulating film 584 is transferred and fixed to the cinnabar paper 591 by the transfer device 592. In this example, the insulating film 584 may be used as an endless, and the toner or electrostatic latent image remaining after transfer may be used.

In this way, the original plate having the conductive part and the insulating part pattern is opposed to the information holding medium having the insulating layer formed on the electrode substrate, and a direct current voltage is applied between the conductive part of the original plate and the electrode of the information holding medium and placed on the information holding medium. By forming the electrostatic latent image corresponding to the pattern of the original plate, the original plate can be reproduced on the information bearing medium easily and many times at high speed. In addition, copying can be performed at a very high speed by making a disk into a cylindrical shape. The duplicated pattern can be developed by changing to an electrical signal or by toner phenomenon.

Fig. 86 shows an information recording and reproducing processing method for the purpose of exposing an information bearing medium, where 601 is a mirror, 604 is a developer, 605 is paper or film, 606 is a transfer device, 607 is a fixing roll, and 608 is a supply. A roll, 609 is a winding roll, and 610 is an eraser.

Scanning light or slit light, such as a laser beam that irradiates an unillustrated original surface, is irradiated to the photosensitive member 1 with the mirror 601 interposed therebetween. The photosensitive member 1 has an elongated shape perpendicular to the ground, and a predetermined voltage is applied between the photosensitive member 1 and the information bearing medium 3 on the rotating drum. As a result, an electrostatic latent image is recorded on the drum-shaped information holding medium 3 according to the image density of the original. The electrostatic latent image formed is transferred to paper or film 605 by a transfer device 606 made of a toner in a developing device 604 and made of a corotron or the like, and fixed to a fixing roll 607 incorporating a heater. The charge on the information bearing medium remaining after the transfer is erased by the image 610 and is prepared for the next exposure. The eraser 610 is for leaking the charge on the information holding medium 3, and may be any conductive material such as liquid or solid, and may be capable of leaking charges by contacting the information holding medium. The residual charge may be canceled by.

Since the information holding medium exposure strategy in this embodiment allows the image information to be recorded on the information holding medium 3 as an electrostatic latent image, the latent image is stably maintained for a long time, and as a result, it does not require strict potential control such as a conventional copier. In addition, even a small amount of light can be responded to, thereby reducing the voltage reduction and the power consumption of the exposure apparatus.

87 is a view showing another embodiment of the present invention, in which the same numbers as in FIG. 2 denote the same contents. 620 is a magnetic brush developing device, 621 is a rotating magnet, and 622 is an electrode.

In the present embodiment, the information bearing medium is a paper or film insulator, and the same thin and long electrode 622 is formed to face the thin film and long photoreceptor 1 in a direction perpendicular to the ground. It is arranged separately, and a predetermined voltage is applied between the photoconductor 1 and the electrode 622 so that an image is recorded on an insulator on paper or film.

Next, a description will be made of the elongated photosensitive member 1 with laser scanning light or slit light in a document (not shown). On the other hand, the information bearing medium 3 in the form of paper is continuously conveyed to the supply roll 608 and the winding roll 609 while being in contact with the electrode 622, and the voltage between the photosensitive member 1 and the electrode 622 is maintained. The electrostatic latent image is sequentially formed on the information holding medium 3 in accordance with the image information by applying. The electrostatic latent image formed on the paper-like information bearing medium is toner developed by the magnetic brush developing device 620, and a toner image is formed as shown in Fig. 87 (b). The magnetic brush developing device 620 has a rotating magnet 621, whereby magnetic toner particles rotate in a brush shape by rotation of the magnet, and are developed in contact with the recording medium. Then, it is fixed by the fixing apparatus which is not shown in figure.

In this embodiment, since the information bearing medium itself is a copy medium, the transfer step can be omitted. Of course, the paper-type information holding medium may be transferred back to another paper or the like. In addition, as long as the information bearing medium can stably maintain the latent image potential for a long time, the development can be performed at any point in time, and the latent potential forming portion and the developing portion can be separately formed even when the device is constructed.

88 is a view showing another embodiment of the present invention for surface exposure.

In this embodiment, the photoconductor 1 is formed on the surface, and the paper or film-like information holding medium 3 is formed on the same surface as the photoconductor with the electrodes 622 narrowly arranged to face the photoconductor 1. Then, the information holding medium 3 is intermittently sent, stopped at a predetermined position during exposure, and sequentially exposed. Since surface exposure is thus performed, it is possible to significantly shorten the exposure time.

FIG. 89 (a) shows a configuration in which the magnetic brush developing device 620 is disposed opposite to the photosensitive member with respect to the information bearing medium. The information holding medium 3 is a simple film without electrodes as shown in FIG. 89 (b). Then, the magnetic brush developing device is grounded, and a predetermined voltage is applied to the electrode of the photoconductor 1. When the original surface is irradiated by the light source 602 and the photosensitive member 1 is exposed to the surface by the reflected light, an electrostatic latent image is formed on the film-like information bearing medium 3 and the toner is developed at the same time. . The developing device 620 has a rotating magnet 621 and rotates the magnetic toner supplier to develop the magnetic toner particles in the form of a brush so as to contact the information holding medium 3, and the toner image is developed simultaneously with the exposure apparatus. It is formed on the opposite side. In this case, since the developing device also functions as an electrode and earths the charge of the information holding medium with the magnetic toner particles interposed therebetween, it is preferable to face the information holding medium over the entire exposure surface. Place the developer. Thus, after developing, it adheres passionately with the heater 607.

In addition, in the case of this embodiment, since the information bearing medium does not have an electrode as a film-like insulator, the developing device also functions as an electrode, and as a result, a large developing device or a plurality of developing devices may be required. It is preferable to use an exposure method by slit light or scanning beam light instead of surface exposure, and to develop the developing apparatus into a thin and small shape.

FIG. 90 (a) shows the case where the magnetic brush phenomenon 620 is disposed on the same side of the photosensitive medium as the photosensitive medium, and the information holding medium 3 has the insulating layer support 15 as shown in FIG. 90 (b). The electrostatic latent image is formed by exposing and applying a predetermined voltage between the electrode of the photoconductor and the electrode 13 of the information bearing medium. Then, development may be performed after an arbitrary time after exposure, and the toner image is formed on the exposure side.

91 is a diagram showing an embodiment of an information-recording / playback processing apparatus for the purpose of electrostatic copying.

The surface of the document 601 is irradiated with the light source 602, and the reflected light is irradiated to the photosensitive member 1. A predetermined voltage is applied between the photosensitive member 1 and the information holding medium 3, and the photosensitive member 1 is surface-exposed with light having image information from the original surface, and is conductive according to image density. As a result, an electrostatic latent image is formed on the information bearing medium 3 according to the image of the document 601. On the other hand, the information holding medium 3 is conveyed to the conveyance belt 603 and toner developed by the developing device 604. The toner developed information holding medium 3 is transferred to a transfer film 105 made of toner on the information holding medium 3 using ordinary copy paper or film by a transfer device 606 made of corotrone or the like. The toner image on the transfer film is fixed by the heater 607. Since the information holding medium 3 also reacts to weak light, the light source 602 does not have to be as large as that used in a conventional copier, and the electrostatic latent image of the information holding medium can be stably maintained for a long time. Therefore, it is not necessary to develop immediately after the electrostatic latent image is formed, but it is also possible to save it in the state of the information retention agent which has formed the electrostatic latent image, and to develop and transfer at any point thereafter at any time thereafter. Therefore, the electrostatic latent image forming portion, the developing portion, and the transfer portion are not the same device, but can be configured as separate devices.

Fig. 92 is a diagram showing another embodiment of an information recording and reproducing processing apparatus for the purpose of electrostatic copying.

In this embodiment, as the light source, a slit light source is used to scan the original surface, and the photosensitive member 1 is a thin and long shape with respect to the slit light source, and the rotating drum-shaped information holding medium 3 is used to sequentially scan the original surface. The electrostatic latent image is formed in accordance with the image density. Operation of the apparatus is the same as that shown in FIG.

Incidentally, in the illustrated example, the transfer film is a continuous image, but may be a sheet for each sheet as in a normal copier.

Moreover, you may use the laser beam which intensity-modulated using modulators, such as AOM, as a light source. In this case, it is not necessary to scan the original surface with laser light, and the laser light may be modulated by the image data read out from the memory sequentially or the laser light may be modulated with the signal while the original is read by the CCD line sensor.

93 is a view showing an embodiment of an information recording and reproducing processing method for toner image formation, in which 621 and 623 are chargers, 625 are transfer films, and 627 are infrared lamps.

The toner is composed of dry toner and wet toner, and is composed of dye, pigment and colored fine powder with resin applied thereto, but the former is charged by iron, glass beads or frictional friction of their own, and the latter It is charged by adsorption and dispersed in an insulating solvent.

The development occurs by contacting the toner to the information bearing medium 3 on which the electrostatic latent image has been formed. However, when the toner image having the polarity and the polarity of the charge of the electrostatic latent image is used, a toner image corresponding to the electrostatic latent image is obtained, When toner is used, an inverted image of a peak latent image is obtained as a toner image. Black circles in the figure indicate negative charge toners, and white circles indicate positive charge toners.

When the toner image is formed, toner transfer is performed next. This is done by compressing the transfer film 625 onto the information bearing medium 3, and performing a corona discharge of toner particles and reverse polarization with a charger 623, or applying a bias voltage of polarity to stick the toner particles. Lose.

When the transfer is performed in this way, passion deposition is performed by the infrared lamp 627 or a heat roll (not shown), and the phase change is completed.

Since the information bearing medium of the present invention can retain charge for a long time, it is not necessary to form a toner immediately after formation of an electrostatic latent image by strong light as in the electrophotographic method used in a copying machine or the like, and the toner development may be performed at any point in time.

Fig. 94 shows a case where color synthesis is performed on an information holding medium in which toners are formed on a three-sided electrostatic latent image in R, G, and B, and the information holding medium 3 has a transfer roll 631 attached with a transfer film 633. Squeeze in. If the circumference of the transfer roll 631 is the same as the length of each color, three rotations of the roll form a color image. The black may move the transfer film toward each color to perform color synthesis. In addition, even when the information holding media of R, G, and B are independent, color synthesis can be performed in the same manner.

In the above description, the case where the toner phenomenon, the transfer, and the fixation are used as the final image by itself is described, but the final image may be omitted.

For example, when the information bearing medium 3 is transparent, the toner developed medium can be irradiated with light and viewed as a projected enlarged image, and even when the information bearing medium 3 is not transparent, the toner It is possible to enlarge and view as a reflection image by using the light reflection reduction by. In this case, the projection is simply performed in the case of a single color, and in the case of color, the transmission image or the reflection image of the three-sided division may be synthesized on the projection surface, and if the toner is transparent, it has a filter effect on the transmission image itself. In the case of transparency, a color filter may be disposed in front of the projection surface.

Fig. 95 shows a method of obtaining a transmission image of the toner image formed on the information bearing medium 3, wherein 640 is a light source, 641 is a lens, 643 is a filter, and 645 is a screen.

The information holding medium 3 is composed of a transparent insulating layer 11, a transparent electrode 13, and a transparent supporter 15, and irradiates light from the light source 640 on the transparent supporter side 15, and transmits toner images. The image is projected onto the screen 645 through lens 641, filter 643. In this case, the black and white toner can project the black and white image, and the color toner can be combined by combining the color toner and the filter on the screen 645 to obtain a color-to-image.

Fig. 96 is a view for explaining a method of obtaining a reflection image of a toner image formed on an information bearing medium.

In this example, the electrode 13 forms a light reflection layer and reflects light from the light source 640 to form a projection image on the screen 645. In this case, black and white or color toe images can be obtained.

In this way, an electrostatic latent image is formed on the information bearing medium as an analog amount on the surface, and this is developed as a lower particle to perform phase conversion from the latent image to the developing image. This makes it possible to form the toner image at any time from the stored image information.

97 through 99 show an embodiment of the color recording medium of the present invention.

Fig. 97 (a) is a perspective view of the ROM type electrostatic charge card-like recording material of the present invention, and Fig. 97 (b) is a sectional view taken along line AA in Fig. 97 (a), showing a state when the protective film is covered. Fig. 99 (a) is a perspective view of the DRAW type static charge card image recorder of the present invention, and Fig. 99 (b) is a sectional view taken along line BB of Fig. 99 (a). In the figure, 650 is a recording body on the electrostatic charge card, 651 is a card substrate, and 653 is a protective film.

The electrostatic recording body 3 shown in FIG. 98 corresponds to the example of the information holding medium described in FIG. In this case, as long as the support 15 has a strength that can support the electrostatic electromechanical body 3 with strength, the material and thickness thereof are not particularly limited. For example, a flexible plastic film, a metal foil, Paper, or rigid bodies such as glass, plastic sheets, and metal plates (which may also serve as electrodes) are used.

Except in the case of using a metal plate as an electrostatic chromosome support, the electrostatic chromosome electrode is formed by laminating a film thickness of about 1000Å by means of aluminum deposition or the like on the support, and then the insulating layer, which is the electrostatic chromosome material, is laminated. An electrostatic charge body is produced. In addition, the electrostatic blocking member 15 may be omitted, and the electrostatic blocking member 13 and the insulating layer 11 may be sequentially stacked directly on the card base 651. In addition, a metal plate may be used as the electrostatic corrugator support, and the electrostatic corrugator support and the electrode may be combined.

The electrostatic recording body 3 is attached to or embedded in the card base 651 as shown in FIG. 97 or 99 after recording the information or before recording the information. The card base 651 on which the electrostatic proteome 3 is placed has a strength that can support the electrostatic proteome 3, and the material and thickness thereof are not particularly limited. Plastic sheet, glass, such as vinyl resin. Rigid bodies such as ceramics and metal plates (which may also serve as electrodes) are used.

The electrode 13 is formed on the electrostatic stopper support 15 in accordance with the formation pattern of the front surface or the insulating layer between the electrostatic lookup support 15 and the insulating layer 11, and its material has a resistivity of 10 ⁶ kPa. It is not limited if it is cm or less, An inorganic metal conductive film, an inorganic metal oxide conductive film, etc. are used. The electrostatic protoplast electrode 13 is formed on the electrostatic protoplast support 15 by deposition, sputtering, CVD, coating, plating, dipping, electrolytic polymerization, and the like. Moreover, the thickness is about 100-3000 mm when aluminum is used.

Since the insulating layer 11 laminated on the electrode 13 records information on the surface black as a distribution of electrostatic charge therein, high insulating property is required in order to suppress the movement of charge, and the resistivity is 10 ¹⁴ Pa · cm It is required to have the above insulation. Such an insulating layer 11 can be formed by dissolving resins and rubbers in a solvent and coating, dipping, vapor deposition, and sputtering, and the film thickness of at least 1000 kPa (0.1 µm) is required in terms of insulation properties. 100 micrometers or less are preferable at the point of flexibility.

In addition, an adhesive is placed on the protoplast electrode 13 to electrostatically charge a silicon film, a polyester film, a polyimide film, a fluorine-containing film, a polyethylene film, a polypropylene film, a polyparabanic acid film, a polycarbonate film, and a polyamide film. The layer is formed by laminating it, or by coating and dipping by adding a curing agent, a solvent and the like necessary for a thermoplastic resin, a thermosetting resin, an ultraviolet curing resin, an electron beam curing resin, a rubber, and the like. Moreover, the monomolecular film or monomolecular film formed by the Langmuir Project Method can also be used.

The insulating layer 11 can be provided with a charge holding enhancement layer between the electrode surface or on the insulating layer 11. The charge holding layer is strengthened, strong electric field (10 ⁴ V / ㎝ or more) is applied when the charge is injected, but low electric field (10 ⁴ V / ㎝ below) refers to a small amount of charge injection layer in. As the charge holding reinforcing layer, for example, SiO ₂ , Al ₂ O ₃ , SiC, SiN, or the like can be used. As the organic material, for example, a polyethylene deposition film or a polyparaxylene deposition film can be used.

In addition, in order to maintain the electrostatic charge more stably, a substance (donor material) having electron donation and a substance (acceptor material) having black electron acceptability may be added to the insulating layer 11. As donor materials, there are styrene-based, pyrene-based, naphthalene-based, anthracene-based, pyridine-based and adine-based compounds, specifically, tetrathioflubarene (TTF), polyvinylpyridine, polyvinylnaphthalene, polyvinylanthracene, polyadine, Polyvinylpyrene, polystyrene, and the like are used, and one kind or a mixture thereof is used. As the acceptor material, there are a halogen compound, a cyan compound, a nitro compound, and the like. Specifically, tetracyanoquinomimethane (TCNQ), trinitrofluorenone (TNF), and the like are used. Donor material and acceptor material are used by adding about 0.001-10% with respect to resin.

Further, in order to safely maintain the static charge, fine particles may be added to the electrostatic chlorophyll. Examples of the particulate material include periodical group IA (alkali metal), copper IB (copper), copper IIA (alkaline earth metal), copper IIB (zinc), copper IIIA (aluminum), copper IIIB (rare earth) , East IVB group (Titan group), East VB group (Vanadium group), East VIB group (Chromium group), East VIIB group (Manganese group), East VIII group (Iron group, Platinum group), East IVA group (Carbon group) ), Silicon, germanium, silver, lead, copper VA (nitrogen), antimony, bismuth, and copper MA (oxygen), sulfur, serene, tellurium are used as fine powder. In the particulate material, metals can also be used in the form of metal ions, finely divided alloys, organometallics, and complexes. Moreover, the particulate material can be used in the form of oxides, phosphorous oxides, sulfur oxides, and halides. These additives may be immersed in a very small amount of the electrostatic charge body such as the above-mentioned resin, rubber, etc., and the amount of addition may be about 0.01-10% by weight relative to the electrostatic charge body.

The insulating layer 11 thus formed may be provided with a protective film 653 on its surface as shown in Fig. 97 (b) in order to prevent breakage or discharge of information charges on the surface thereof. As a protective film, rubber | gum, such as adhesive silicone rubber, resin, such as polyterpene resin, may be made into a film form, and it may adhere | attach on the surface of the insulating layer 11, or stick a plastic film using adhesives, such as silicone oil, even if it adheres. The specific resistance is 10 ¹⁴ Pa.cm or more, and the film thickness is about 0.5-30 µm. In particular, when it is necessary to make the information of the insulating layer 11 high resolution, since information is read out on a protective film, the film thickness of a protective film is so good that it is thin. When the information is read out, the information may be reproduced on the protective film or the protective film may be peeled off to directly reproduce the information in the insulating layer.

The information recording card 1 incorporates information already recorded in the electrostatic recording body as shown in FIG. 97 (hereinafter referred to as ROM type) or has a partial recordable portion (hereinafter referred to as DRAW type). You can do In the case of the DRAW type, the protective film may be peeled off the surface of the insulating layer, for example, a plastic film having the above-mentioned adhesiveness may be used, and during the recording, the protective film is peeled off and recorded on the unrecorded part. Should be able to cover the second insulating layer surface. In addition, it is necessary to apply a voltage to the electrode during recording, and therefore, the electrode terminal 13a is provided on the back surface of the card base 651.

In the above description, the ROM type and the DRAW type have been described, but the electrostatic latent image can be easily erased as described above, and needless to say, the E-DRAW type can be written and erased.
