Description

The present invention relates to an image recording system for recording an optical image of an object such as a document or a landscape, and more particularly, to record the optical image in a lightweight and simple manner, and further to record it as an electric signal. The present invention relates to an image recording system for recording or outputting as.

[Prior art]

Conventionally, as a means for recording an image, an original is recorded by electrophotography as an electrostatic latent image on a copying medium through an optical system, and then a visualized image is formed by liquid or dry toner (ink), which is recorded on paper or the like. There are various methods such as a method of transferring to a medium or a method of reading an image by a digital photoelectric conversion element using a CCD (Charge Coupling Device) or the like and converting this to an electric signal for output.

[Problems to be Solved by the Invention] However, according to the former electrophotography, while a high-density image is clearly recorded in multiple gradations, usually, a toner is directly applied to a copy medium to make it visible. In order to obtain a recorded image of a desired size, the size of the apparatus becomes large, and the weight and size of the apparatus increase. In particular, when visualizing a color image, a plurality of latent image forming media are required, so this drawback is particularly remarkable. Further, since a plurality of types of toner are required, the maintenance and cost of the apparatus are also reduced. It is a disadvantage.

On the other hand, when reading an image with the latter digital photoelectric conversion element such as CCD, if this is a one-dimensionally arrayed element, the document is mechanically scanned, or if it is formed into a two-dimensional arrayed element, a high-density image becomes clear. In order to read, a large number of elements must be finely processed correspondingly, resulting in high cost. Further, when storing images, there is a problem that an external memory must be provided. Further, in reading a color image, the color filters have to be dispersedly arranged on the CCD surface, and the cost increase due to the fine processing of the device is more remarkable.

On the other hand, when an image is converted into an electric signal by a vacuum tube system typified by an image orthicon or vidicon, it is possible to read an image at a very high speed and at a high density without fine processing.
Also, an external memory (for example, video tape or the like) for storing this is required. Therefore, when a portable recording device is constructed, the memory means or the power source for driving the vacuum tube requires a certain size, which is not optimal for portable use.

On the other hand, silver salt photographs are capable of high-density recording, and because image storage on the film is effective, the camera section and development are separated and independent, and it is very convenient because only the camera needs to be carried. This process has the drawback that it cannot be used repeatedly and that chemicals must be used in the development, making this process complicated.

In view of the above-mentioned drawbacks, the present invention records an image using a medium that can be carried repeatedly and is capable of holding a high-density image, and outputs the held image as an electric signal. The purpose is to provide an image recording system that can be restored.

Another object of the present invention is to provide an image recording system capable of recording or storing a high resolution color image.

[Means for solving problems]

In order to solve such a problem, in the present invention, a photoelectric conversion member for converting an optical image into electrical image information is provided as a thin film shape on a disk-shaped base member, and the photoelectric conversion member is rotated. An optical image is sequentially incident on a plurality of different portions of the photoelectric conversion member, and a plurality of optical images are incident along the radial direction at each rotation position of the photoelectric conversion member.

[Action]

A photoelectric conversion member is provided in the form of a thin film on a disk-shaped base member, and by rotating the member, optical images are accumulated in a plurality of portions, and further, a plurality of images are accumulated in the radial direction at each rotation position. Therefore, a large amount of image information can be stored with a relatively compact structure by effectively using an image storage body having a limited area, and unnecessary charging and colorization can be easily realized.

〔Example〕

1 and 2 are diagrams showing a typical configuration example of the image recording system of the present invention. FIG. 1 is an upper perspective view, and FIG. 2 is a front perspective view.

The basic configuration of the image recording system of the present embodiment is a film-shaped image accumulating body 4 for electronically accumulating images, and the image accumulating body 4

More specifically, the recording unit 1 includes an optical system 11 and an exposure member EM including a diaphragm shutter, etc., and is configured to control the amount and time of passage of an optical image by the optical system 11.

Reference numeral 102 denotes a holding container in which the image storage body 4 is stretched around the winding shafts 41 and 42. This winding shaft 41,4
Rotor magnets 501 and 502 are fixed to one end of the shaft 2, and the shafts 41 and 42 are rotatably attached together with the magnets 501 and 502 by bearings (not shown) of the stage 101.

Although the stage 101 is omitted in FIG. 1, the beam scanning unit 21 is fixed on the stage 101.
The beam scanning unit forms an electric field or a magnetic field, and by changing the electric field, the electron beam emitted from the electron gun 23 is deflected to scan a predetermined screen of the storage body with the electron beam.

Reference numeral 23 denotes an electron gun. The beam emitted from the electron gun is focused and deflected by the beam scanning unit 21 and then irradiated on the storage body 4 through the mesh electrode 200, and secondary electrons emitted from this storage body are used as mesh electrodes. It is configured to detect at 200. A lead wire (not shown) is transmitted from the mesh electrode 200 through the wall surface of the holding container 102 and is connected to the output terminal of the connector 3.

Further, it is preferable to apply a predetermined positive bias voltage to the mesh electrode via the lead wire.

The above winding shafts 41, 42, magnets 501, 502, stage 10
1, the beam scanning unit 21, the electron gun 23 and the like are housed in a holding container 102, and the inside of the container 102 is kept in a vacuum.

The electron gun 23, the power supply terminal of the beam scanning unit 21, the signal input terminal,
The output terminal is provided on the connector 3, and this connector 3 can be exposed to the outside of the camera 100.
Are covered by. Reference numeral 202 denotes a connector for supplying a power beam focusing / deflecting signal from the recording / reproducing apparatus 204 to the camera 100 via the cable 203, and for inputting an image signal output from the camera 100. The connector 202 and the connector 203 are Connection is possible with the lid 201 open. An external power input terminal 207 is provided on the connector 3, and when the connector 202 is connected to the connector 3, the recording / reproducing device 2
The power from 04 is also supplied to this terminal 207. This terminal is connected to one end of the switch 205. At the other end of switch 205 is a battery pack 5.
Is connected to the internal power source, and these two types of power sources are selectively supplied to the drive circuit 208 for driving the coils 503 and 504 and other electric circuits. Further, 206 is a system controller, which includes a shutter switch 13, a lid.
An open / close signal of 201 is input, and when the lid 201 is opened, the switch 205 is connected to the terminal 207 side. If the lid 201 is closed, the battery pack is switched to the battery pack 5 side.

Reference numerals 210 and 211 are light emitting diodes (LEDs) for irradiating the storage body 4 with light as described later. 14 is a finder.

With this configuration, when the image is recorded by the camera 100, the drive circuit is set by the battery pack inside the camera.
Electric power is supplied to 208, and the accumulator 4 is intermittently moved at a predetermined timing to record an optical image as a latent image on the accumulator one screen at a time.

When the connector 202 of the recording / reproducing apparatus 204 is connected to the connector 3 of the camera 100 at the time of reading, the lid prior to this is connected.
With the opening of 201, the power supply line is switched by the switch 205, and the recording / reproducing device 204 can supply power.

Therefore, when the camera is carried, the power source becomes compact and the camera can be miniaturized.

Further, since the internal power source and the external power source are switched in connection with the connection operation of the connector 3 and the connector 202, the limited power source in the camera is not consumed when reading an image from the storage body.

Further, in the embodiment, since the image storage body 4 is enclosed in the vacuum chamber and can be moved from the outside, a large amount of high resolution image information can be stored.

Moreover, reading can be done in one touch, and a special large-scale reading device unlike the conventional case is not required.

Further, since the drive shaft for moving the accumulating member 4 can be driven by the electromagnetic force from outside the vacuum holding container, the degree of vacuum can be maintained more easily than when the motor is enclosed in the holding container.

In the present invention, what is recorded in the image storage body 4 may be an electronic latent image pattern, for example, an electrostatic latent image or a latent image based on an electronic trap distribution.

When the latent image pattern as described above is scanned with an electron beam, the contrast of the image recorded in the accumulator is detected depending on the amount of secondary electrons emitted from the image carrier corresponding to the latent image. Thus, the latent image can be converted into an electric signal and read. The accumulator 4 may be provided on a rotating disk having a glass substrate instead of the accumulator 4. By doing so, the planarity of the storage body can be stably obtained.

Incidentally, in the above-mentioned embodiment, the secondary electron is detected by the mesh electrode, but the return beam due to the reflection of the electron beam may be detected as described later.

Hereinafter, each part of the image recording apparatus of the present invention will be sequentially described in detail.

First, the image storage body and the image recording method of this embodiment will be described in detail.

FIG. 3 is a vertical cross-sectional view of the image storage body 4 used in the embodiment of FIGS. 1 and 2, which has a film shape as a whole, and a barrier layer 50 and a transparent conductive layer 51 on a transparent substrate film 56. , An N-type photoconductor layer 52, a transparent insulating layer 53, and a semiconductive layer 55 are laminated. The layers 56 will be described below. The substrate 56 is made of a material that has sufficient flexibility and translucency and is not cut by the tension during film loading. For example, polymer films such as polyethylene terephthalate and polyimide are preferable. In order to satisfy the above characteristics, the film thickness is 10% for polyethylene terephthalate.
~ 50μm is desirable, 5 ~ 50μm for polyimide film
m is desirable. As the transparent conductive layer 51, tin oxide, indium oxide, or a material containing a small amount of tin oxide is used. This layer is formed by a known method such as sputtering, and preferably has a thickness of several tens to several hundreds nm in terms of a thickness capable of obtaining translucency and sufficient conductivity.

The N-type photoconductor layer 52 is formed by vapor-depositing or sputtering an N-type photoconductor such as CdS, CdSe, ZnO, etc., and generates sufficient electron-hole pairs by receiving light, and has a dark portion. Is ensured, and the film is formed to a thickness such that the internal diffusion of light can be ignored. For example, the range of 100 nm to several μm is desirable. Next, the insulating layer 53 is a highly insulating thin film such as SiO ₂ or Mgo, and is formed by a method such as sputtering. The thickness of the film is several hundred nm to several tens of μm in order to provide sufficient insulation.
Is desirable. Next, the semiconductive film 55 is a film such as glass or a porous film such as KCl (potassium chloride) for protecting the conductive layer from the beam, and the resistance in the wall surface direction is higher than that in the film thickness direction and sufficient insulation is achieved. In some cases, the film thickness is sufficiently thinner than the resolution width of the recorded image, for example 1000
In order to obtain an image with a resolution of / mm, it is desirable to set the film thickness to several 100 pm to several hundred nm. In addition, the photoconductive layer 52 and the transparent conductive layer 51
The barrier layer 50 provided between the layers is a layer for preventing dark attenuation and injection of negative charges in the dark part, and is formed by depositing CdSO ₃ , CdSeO ₃ or the like by a spatter. This film thickness is 2 to several 10
nm is preferred.

Next, FIG. 4 (a)-
This will be described using (c).

In a dark place, the transparent conductive layer 51 is grounded or negative, and a positive charge is applied to the semiconductive layer 55 by using, for example, a conductive brush or rolls 57 and 57 'as shown in FIG. 4 (a). This imparted positive charge is immediately injected through the semiconductive layer 55. Next, the exposure member EM of FIG. 1 is opened and image exposure is performed, and the resistance of the photoconductive layer 52 decreases at the portion exposed to the light L and negative charges from the transparent conductive layer 51 pass through the barrier layer and are injected into the photoconductive layer 52. Then, the state shown in FIG. 4 (b) is obtained. Next, after the exposed member EM is closed, the transparent conductive layer 51 is dropped to the ground, and the conductive brush or roll 59, 59 'shorted to this ground is used to make the semiconductive layer 5
The positive charge in the dark part and the negative charge in the transparent conductive layer 51 are short-circuited and erased through 5, and the positive charge is applied to the semi-conductive layer 55 as shown in FIG. It is distributed to the transparent conductive layer 51. Next, when the transparent conductive layer 51 is set as ground and the image storage body 4 is entirely exposed by the above-mentioned LEDs 210 and 211, the electric resistance of the photoconductive layer 52 is lowered, and the positive and negative charges on both ends of this layer are erased, and the insulating layer 53 is formed. As shown in FIG. 4 (d), only the electric charges sandwiching the mark are left, and recording is performed with the surface at a positive potential.

According to the image accumulation body and the recording method, since the image accumulation body is collectively formed by using the sputter method, it is possible to form the accumulation body very uniformly, and unevenness occurs in the accumulated image. Factors have decreased. Further, since a thin-layered photoconductor (photoconductor) is used, the light absorption rate is high and high sensitivity can be achieved. Further, the thinning of the photoconductor can increase the image resolution by 10 times or more as compared with the conventional one.

FIGS. 5 and 6 show details of the recording unit 1 in the configuration of the embodiment to which the above-mentioned recording method is applied, and an example of this operation will be described with reference to FIGS. 1 and 2.

By determining the subject and setting the shutter switch 13 in FIG.
A voltage is applied between the charging brush roller 57 and the ground brush 57 'in the figure, and the drive coils 503 and 504 are operated to feed the film in the direction of arrow 60 in the figure.

As a result, first, the image storage body 4 is uniformly charged.

Next, the exposure switch EM is operated by setting the shutter switch 13 to the full switching state, exposing the image accumulator 4 through the optical system 11 in the required amount of light, and recording the image in the state of FIG. 4 (b).

Next, when the shutter switch 13 is released, the drive coil
503 and 504 are actuated, the film is moved in the direction of the arrow 60 by one screen, and the entire surface is discharged by the ground brushes 59 and 59 ', and the image is held and accumulated in the state of FIG.
After that, the film is returned by one screen in the direction opposite to the direction indicated by the arrow 60, so that the film is held at a position convenient for the above uniform charging process of image recording of the next screen.

1 and 5, the holding container 102 is formed of glass or the like, but the holding container 102 is at least the image recording unit 1.
In (1), it is desirable that it is sufficiently transparent, and that it is a flat surface that does not adversely affect the image light, such as distortion interference, in the portion that becomes the optical path for image exposure, and that it is parallel to the image storage body surface.

Alternatively, the optical path portion of the holding container 102 can be directly processed as a lens.

The brush rollers 57, 57 ', 59, 5 in FIGS.
9'is the above-mentioned voltage application and the image storage 4
However, a light tension is applied to it, and it is always maintained at a constant angle with respect to image exposure or electron beam scanning described later, preferably at a right angle to the axis of the optical path. By doing so, the resolution for image recording and reading can be kept good.

In this way, by using the roller or brush for charging and discharging the accumulator 4 as the tension roller for providing the flatness of the recording unit 1 of the accumulator 4, the structure can be simplified.

Further, as shown in FIG. 6 (a), one of the rollers or brushes for charging or discharging, which is grounded, is connected to the outside of the effective screen EF (scanning screen range by electron beam) and film-like accumulation. Provided at the widthwise end of the body 4,
Correspondingly, the structure of the layer of the film-shaped accumulating member 4 is as shown in FIG. 6 (b), so that the structure is further simplified.

Here, it is desirable to retain the recorded image in the image accumulating body 4 in the process end state of FIG. 4 (c).
As shown in FIG. 4 (c), when the surface of the image accumulating body 4 is kept at a potential (ground) at which no electric field is generated outside, the image accumulating body 4 is made into a film and wound for storage. This is because it does not affect each other and the overlapped images, and good images are retained. As we will see later,
This good holding effect is great when a conductive substrate including the substrate 56 and the conductive layer 51 is used.

Of course, the holding in the state shown in FIG. 4 (d) is also possible.

In the above description, the example in which the image is formed by uniformly charging the surface of the image accumulating member has been described, but it goes without saying that other recording methods may be used.

Further, in the recording method of the image accumulating body 4 described above, the conductive brush and the roll are used for removing and charging the accumulating body 4, but an electron gun incorporated in the image recording system of the present invention as a separate means. 23 can also be used. The charging method in this case will be described with reference to FIG.

When the electron gun 23 is used, the conductive layer 51 is used as the back electrode, and the polarity of the charge applied to the semiconductive layer 55 of the image storage body 4 changes due to the acceleration voltage. That is, if a collector electrode is provided in the vicinity of the image storage body 4 at the time of charging, or a collector electrode is provided only at the time of decharging, and the voltage of this electrode is made sufficiently high and the electron beam is a low-speed electron beam, the If the surface of the conductive film 55 is 0 V, the amount of primary electrons from the electron gun toward the semi-conductive layer 55 is larger than the amount of secondary electrons generated by collision until the acceleration voltage of a certain voltage V _A or less. The semiconductive layer will be negatively charged. When the accelerating voltage is V _A , the amounts of primary electrons and secondary electrons are almost equal to each other, and the surface of the semiconductive layer becomes 0V.
Further, when the accelerating voltage is higher than V _A above, more secondary electrons are emitted than the input primary electrons, so that the surface of the semiconductive layer is positively charged. Although the value of V _A varies depending on the material, it is about 20 to 50 V because the lower part of the semiconductive layer is composed of the insulating layer 53. In addition, the above method is possible only because the collector voltage is positive and is sufficiently high and most of the secondary electrons are collected.

Further, when the image storage body 4 is negatively charged, not only the electron gun is used as described above, but also a Tungsten filament is separately installed inside and the thermoelectron emission from this filament can be used. It is possible.

In the above charging method, the charging potential can be controlled by controlling the collector voltage in the region where the secondary electron emission exceeds the primary electron injection. When the surface potential of the semiconductive layer of the image storage body is set to approximately 0 V and charged to + V _C volt, a voltage of − (V _A + α) is applied to the cathode of the acceleration voltage on the electron gun side, and further the collector electrode A desired charging voltage + V _C is applied to, and the conductive layer 51 of the image storage body is grounded. By setting the voltage in this way, the semiconductive layer 55 on the image storage member is
When the secondary electron beam is incident, in the above setting, the secondary electron emission is larger than the primary electron input, and the emitted secondary electrons are all taken into the collector electrode, so that the semiconductive layer is gradually positively charged. When the charge advances and the surface potential exceeds the collector potential, secondary electrons cannot move to the collector electrode, return to the semiconductive layer, and the potential decreases by the amount of primary electron input, and the constant surface potential V _C is maintained. .

Next, a case where the semiconductive layer 55 is negatively charged will be described.
In this case, if the charging potential is -V _C volt, the cathode potential is-
Set to (V _A + V _C + α) volts. However, the surface potential of the semiconductive layer 55 is assumed to be approximately 0V. In this case, since all the emitted secondary electrons return to the semiconductive layer, the semiconductive layer is negatively charged by the input of the primary electrons. When the potential becomes lower than −V _C volt, the potential of the collector electrode becomes positive relative to the surface potential of the semiconductive layer, so secondary electrons are collected and the semiconductive layer is positively charged. It will be. Therefore −V _C
It is stably charged by the bolt.

When charging is performed using the electron gun as described above, a brush,
As compared with a roll or the like, more uniform charging is possible, the charging time is shorter, and the control of the charging position is easier.

Next, the static elimination method will be described. As described above, since the charging can be controlled by the potential of the collector electrode, if the collector potential is set to 0V, the charge can be removed. Also,
Only when the semiconductive layer is positively charged, the collector potential is made sufficiently high so that all the emitted secondary electrons are collected,
If the charged potential of the semi-conductive layer is + V _S and the potential of the cathode is V _K , electron beam irradiation is performed under the condition that (V _S −V _K ) <V _A, and V _S is gradually approached to 0 V to eliminate the charge. It is also possible to do so. However, when V _S <V _A , sufficient static elimination is possible with V _K = 0. Naturally, the conductive layer 51 is grounded in the above static elimination.

As described above, according to the decharging method of the present embodiment, more uniform decharging is possible as compared with a brush, a roll, etc., and decharging is performed without using any mechanical means such as variably controlling the charging potential. The structure is simple because it can be charged.

There is also an effect that the power source becomes small because the current for destaticizing is small and it can be performed at a low voltage.

To erase the image of the image storage body 4, the transparent conductive layer is grounded while the entire surface is exposed as described above, and the conductive brush or roll dropped to the ground is brought into contact with the semiconductive layer 55 to move. This is performed by using the above-mentioned static elimination means. It is possible to irradiate the other image accumulating members with light, with the semiconductive layer of each image accumulating member set to 0 V by the brush or roll for eliminating static electricity or the electron beam and the transparent conductive layer set to 0 V.

Next, the image reading section 2 in the recording apparatus of the present invention will be described. Details of one example are described in Japanese Patent Application Laid-Open No. 54-29915 previously filed by the applicant of the present invention for scanning and reading an electrostatic latent image with an electron beam, and therefore, a brief description will be given here.

In FIG. 1, when a cable 203 from a recording / reproducing apparatus having a reading section driving power source and an external memory section is connected to the connector 3 from the outside, image reading can be performed. The read unit drive control circuit for controlling the beam deflection may be provided in the recording / reproducing apparatus as in the present embodiment, or may be provided in the camera 100.

The read operation will be briefly described. When an electron beam enters the image storage body 4, secondary electrons are generated, but secondary electrons are emitted to the outside of the image storage body in a region within a depth of 0.1 μ at most. It is a thing. However, the secondary electrons emitted to the outside are affected by the surface potential of the image storage body. That is, if the surface potential is positive, the secondary electrons are attracted by it and thus are difficult to be emitted, and if the potential is negative, the secondary electrons are repelled and the amount of secondary electrons increases. Therefore, when the electron beam 5 is incident on the image carrier,
If a mesh electrode 200 for focusing secondary electrons is provided in the vicinity of the photosensitive plate, the output of the electrode 200 corresponds to the surface potential of the spot where the electron beam is hit. That is, this output is obtained by converting the image information recorded in the image storage body into a time series electric signal. The use of the electron beam as the reading means has a number of advantages such that the beam scanning is performed purely electrically by the electron lens and the beam diameter is easily narrowed down to several μ or less so that the resolution is high.

Further, by weakening the electron beam intensity, it is possible to read the latent image on the image storage body with almost no destruction.

FIG. 7 is an example of a configuration in which another reading method is applied to the device of the present invention. The application example of FIG. 7 is particularly similar to the electrostatic charge reading method represented by the image orthicon in the related art, and will be briefly described. When the electron beam 5 is emitted from the electron gun 301, it is focused by the focusing coil 302 and the focusing electrode 303 shown in the figure, and is deflected by the deflection coil 304, so that the image accumulator 4 is obtained.
The upper charge image is scanned, but when the electron beam hits the charge image, a part of the beam neutralizes the positive charges in the charge image, and the remaining electrons become a return beam 5'to the electron gun. Return. Therefore, this return beam 5'has a strong and weak contrast corresponding to the charge image, so that the secondary beam generated from the return beam 5'is received by the dynode 305 in multiple stages and then taken out as an electric signal from the collector 306. You can

Other methods of reading a latent image by an electron beam applicable to the present invention are conceivable, but for the sake of convenience of explanation, they are limited to the above.

Next, the operation of the reading section 2 when the image recording method described with reference to FIGS. 3 and 4 is applied to the present invention will be described with reference to FIGS.

As described in the description of the operation of the recording unit 1, here, the image storage body 4 is arranged after the recording process shown in FIG.
It shall be wound up and held.

Here, the connection to the recording / reproducing device 204 is made by the connectors 3 and 202, and the reading operation is started by a switch (not shown).

As a result, the image of the film held in the above state is
It is possible that the latent image shown in FIG. 4 (d) is brought into the latent image state due to dark decay of the photosensitive layer even if the entire surface exposure shown in FIG. 4 (d) is not carried out due to long-term storage. In the example,
Prior to the electron beam scanning for image reading, the image surface to be read is entirely exposed for a certain period of time with the LEDs 210 and 211 to form an electrostatic latent image as a better surface potential pattern (FIG. 4 (d)).

Next, by performing main scanning of the electron beam, the image is sent in time series to the recording / reproducing device having the external memory and is output or restored as an electric signal by detecting the secondary electron or the returning beam. .

Therefore, it is possible to check the image on the CRT or output it on the printer.

When the image is read by detecting the secondary electrons or the return beam emitted from the image storage body at the time of reading, in the above-described image forming method, the photoconductive layer is P type or bipolar type. Alternatively, the entire surface charging in FIG. 4 (a) may be negatively charged.

FIG. 8 is a diagram showing a configuration example of the recording / reproducing apparatus 204, and 400 is AC.
A code, 401 is an AC / DC converter, 402 is a power supply circuit, 403 is a focusing circuit, 403 is a synchronizing signal generating circuit, 405 is a process processing circuit, 406 is a modulation circuit, 407 is a recording / reproducing switching switch, and 408 is a recording / reproducing head. , 409 is a disk motor, 41
0 is a demodulation circuit, 411 is an encoder, 412 is an output terminal, 413
Is a disk-shaped recording medium.

The AC power supplied from the cord 400 is converted into DC by the AC / DC converter, and then converted into an appropriate voltage by the power supply circuit 402 and supplied to each circuit.

Further, the power is also led to the connector 202 via the cable 203. The focusing / deflecting circuit 403 forms a sawtooth wave for beam deflection based on the horizontal and vertical synchronizing signals from the synchronizing signal generator 404, and also guides this to the connector 202 via the cable 203.

The image signal obtained from the connector 202 via the cable is subjected to various corrections such as α correction, aperture correction, black level clamp, white clip, etc. in the process processing circuit 405, and then the modulation circuit 406 applies modulation suitable for recording to the switch. 407 via head 408 to medium 413 to 1 track
The field amount is recorded. At the time of reproduction, the signal read from the head 408 is returned to the original signal again by the demodulation circuit,
Encoder standard television signal (eg NTSC signal)
It is led to the output terminal 412 after being converted to.

Therefore, by connecting a TV receiver to the NTSC output terminal 412, the image can be monitored one field at a time.

Of course, if two fields are recorded on the disk-shaped medium, this can be read as a frame image and monitored.

Needless to say, the encoder here may be compatible with the PAL or SECAM system.

9 and 10 show a modified example of the embodiment of the present invention in which the image exposure surface for image recording and the electron beam scanning surface are on the same side of the image recording body 4. In the configuration shown in the figure, the image accumulator 4 can store the latent image pattern, and the container
This has a great effect in combination with the fact that the storage portion for a plurality of images is provided in the 102.

FIG. 9 is a view to which the image recording method shown in FIG. 5 is applied. Since the image exposure surface for image recording is the same as the electron beam scanning surface, the substrate 56 and the conductive layer in FIG. Since it is not necessary to make 51 transparent, for example, the base 56 and the conductive layer 51 can be combined and formed of a conductive base such as a metal thin body, so that triboelectrification can be prevented. Further, since the scanning and reading unit is horizontally held, the structure of the camera in the optical axis direction can be made compact. In this case, it is desirable to subject the conductive substrate to a treatment such as blasting or vapor deposition of an antireflection film so that flare or interference cannot be exceeded during the image exposure.
In addition, brush and roller 5 for grounding in the figure
Either 9'or 57 'may be used.

FIG. 10 is a further modified example of the configuration shown in FIG.
The description of the recording unit is omitted. In the case of this embodiment, the thickness of the camera in the photographing optical axis direction is not reduced, but the structure of the accumulator as described above can be simplified.

FIG. 9B shows an example in which a secondary electron is detected in accordance with a latent image by electron beam scanning as described above, and a collector CED for detecting the secondary electron is provided in place of the mesh electrode. .

Further, in the recording section, a configuration example of the transparent electrode 600 and the ground electrode 57 'for applying a voltage to the image storage body is shown. Incidentally, 700 is an interchangeable lens.

FIG. 11 shows another embodiment of the film loading means. In the example of FIG. 11, the mounting positions of the magnets 501 and 502 and the drive coils 503 and 504 in the loading means shown in FIG.
A magnet 602 is provided on a support frame 605 outside the container 102. Electric current is supplied to the drive coil 601 by the energizing brush 603 shown in FIG. The structure shown in FIGS. 2 and 11 is the same as the normal DC motor structure and can be driven by a known method.

Here, the image recording system of the present invention can be improved by further performing the following procedure with respect to the embodiment shown in FIG. That is, when reading the image of the magnet 602,
The configuration is such that it can be separated from the container 102. By doing so, it is possible to prevent the magnet 602 from magnetically affecting the electron beam scanned during reading.

FIG. 12 shows an example of means for separating the magnets 602. In the example shown in FIG. 12, the support frame 605 to which the magnet 602 is attached also serves as the lid 201 ′ of the connector 3. After the image recording on the image carrier 4 is completed, the lid 201 'is opened in order to ground the connector 202 from the outside to the connector 3 at the time of reading. At this time, as shown by the arrow in FIG. The magnet 602 is also separated from the container 102 at the same time by sliding the magnet downward with respect to the exterior of the device. Further, it is desirable that the supporting frame 605 be connected to the main body with, for example, a string so as not to be lost when the magnets are separated.

FIG. 20 shows an example in which the film winding is manual. In the illustrated example, the winding lever 700 is used to move the magnet 701.
And the take-up shaft of the image accumulator 4 with this.
The magnet 702 fixed to 702 is rotated.

By providing the manual hoisting lever 700 as in this example, among the operations of the recording unit shown in the examples of FIGS. 1 and 2, for example, the operation in the half-switching state described above can be performed by interlocking with the manual hoisting lever. Well, by separating from the shutter switch, malfunctions can be reduced.

In the embodiment, the magnetic shield plate 704 is replaced with the magnets 701, 70.
Since it is provided between the beam scanning unit 3 and at least the beam scanning unit 21, it does not interfere with beam scanning. Of course, it may be provided outside the container 102.

In FIG. 20, the magnet 701 can be separated from the container 102 in the same manner as described above by pulling up the entire winding lever at the time of reading.

FIG. 21 shows a camera 100 and a reading unit 2000 according to the present invention.
The parts that can be removed are used as the joining members.
It is possible to combine using 1001 and 1002. Here, the combination of the camera 100 and the reading unit 2000 is the interchangeable lens unit 1010.
To remove.

By doing so, the carrying of the recording unit (camera) becomes more convenient. The camera (recording unit) 100 has necessary charging means, film driving means, and other means as shown in the recording method described above. Also, in order to keep the reading section 2000 in close contact with the film surface and to maintain flatness, a holding plate 10
05 was set up. After the image is recorded by the camera 100, the lens unit 1010 is detached at the time of reading and is joined to the reading unit 2000 instead. At this time, the film and the multi-row pin electrodes of the reading unit 2000 are connected.
It is brought into close contact with the joining plate 1021 having 1020. Elastic member
1030 is provided to ensure this close contact.
The multi-row pin electrodes 1020 are arranged in high density without their respective pins contacting each other in the lateral direction, and are electrically connected to the front and back of the bonding plate 1021 independently of each other. The latent image can be read with the electron beam.

As in this embodiment, the present invention includes a recording unit and a reading unit which can be separated from each other. As described above, the embodiment of the present invention has the greatest feature in that the recording unit and the reading unit can be independently driven without changing their respective states.

That is, the camera 10 stores the accumulation body recorded in the recording unit.
In a method of taking out from 0 and enclosing it in the container 102 of the reading section by some method and reading it in a vacuum state, the recording and reproduction as a camera becomes extremely complicated and it is difficult to be a commercial product, but according to the present invention, the recording operation in the recording section And the reading operation in the reading section are independent of each other, and each operation is performed as it is without changing the states of the recording section and the reading section. Since the recording information of the accumulator can be read out, recording and reading can be performed immediately.

Next, another example of the image storage body and the image recording method that can be used in the present invention will be described in detail.

FIG. 13 is a vertical cross-sectional view of the image accumulating member 4 used in the present invention, which has a film shape as a whole, and a transparent conductive film 51, an N-type photoconductive material layer 52, and 56 on a transparent base film. The transparent insulating layer 53, the P-type photoconductor layer 54, and the semiconductive layer 55 are laminated. Each layer will be described below. The base 56 is made of a material that has sufficient flexibility and translucency and is not cut by the tension during film loading. For example, polymer films such as polyethylene terephthalate and polyimide are preferable. The thickness of the film is 10 to 50 μm for polyethylene terephthalate to satisfy the above characteristics.
m is desirable, and 5 to 50 μm is desirable for polyimide film. As the transparent conductive layer 51, tin oxide, indium oxide, or those containing a small amount of tin oxide is used. This layer is formed by a known method such as sputtering, and preferably has a thickness of several tens to several hundreds nm in terms of a thickness capable of obtaining translucency and sufficient conductivity.

The N-type photoconductor layer 52 is formed by vapor-depositing or sputtering an N-type photoconductor such as CdS, CdSe, ZnO, etc., and generates sufficient electron-hole pairs by receiving light, and has a dark portion. The insulating property is ensured, and the film is formed to a thickness where the internal diffusion of light can be ignored. For example, the range of 100 nm to several μm is desirable. Next, the insulating layer 53 is a highly insulating thin film such as SiO ₂ or MgO, and is formed by a method such as sputtering. The thickness of the film is preferably several μm to several 100 μm in order to provide sufficient insulation. Next, the P-type photoconductor layer 54 is formed by vapor-depositing or sputtering an N-type photoconductor such as amorphous Se or SeTe amorphous Si. The film forming conditions are N-type photoconductor.
According to that of 52.

Next, the photoconductive film 55 is a film such as glass or KCl.
A porous film of (potassium chloride) or the like, which has a resistance in the film surface direction higher than that in the film thickness direction and exhibits sufficient insulation, and the film thickness is preferably sufficiently thinner than the resolution width of the recorded image. For example, if the image has a resolution of 1000 lines / mm, the film thickness is several hundred pm.
~ It is desirable to be several tens of nm.

Next, FIG. 14 (a)-
This will be described using (c).

In the dark place, the transparent conductive layer 51 is grounded or negative, and a positive charge is applied to the semiconductive layer 55 by using a conductive brush or roll 257 as shown in FIG. 14 (a). This imparted positive charge is immediately injected through the semiconducting layer 55 and FIG. 14 (b).
It becomes like. Next, a predetermined amount of image exposure is performed by the exposure member EM of the first illustrated apparatus, and the portion exposed to the light L is the photoconductive layer.
The resistances of 52 and 54 are lowered, negative charges are injected from the transparent conductive layer 51 to the photoconductive layer 52, and positive charges are further injected to the photoconductive layer 54, and the state shown in FIG. 14C is obtained. Next, the exposed member EM is used to shield light, the transparent conductive layer 51 is further dropped to the ground, and the conductive brush or roll 259 short-circuited to the transparent conductive layer 51 passes through the semiconductive layer 55 and the positive charge and the transparent conductivity of the semiconductive layer 55 in the dark area. Layer 51
The negative charges are erased and positive and negative charges are injected into the semiconductive layer 55 and the transparent conductive layer 51 as shown in FIG. Next, when the transparent conductive layer 51 is set as ground and the image storage body 4 is entirely exposed by the LEDs 210 and 211, the electric resistance of the photoconductive layers 52 and 54 is reduced, and the positive and negative charges at both ends of this layer are erased, and the insulating layer 53 is removed. As shown in FIG. 14 (e), only the electric charges sandwiching the mark are left, and recording is performed with the surface at a positive potential.

According to this recording method, as shown in FIG. 14 (e), the accumulated charge image is retained inside the image accumulator, so that the storability is improved as long as it is left in the dark.

Next, a modified example of the image storage body 4 and the recording method described with reference to FIG. 13 will be described with reference to FIG. The image storage body 4 shown in FIG. 15 is replaced with an electrode plate 59 having a surface in contact with the P-type photoconductor layer 54 as a conductive layer instead of the semiconductive layer 55 in the image storage body 4 shown in FIG. The other configuration is the same as that of the image storage body 32. The electrode plate 59 has a conductive layer formed by depositing tin oxide, indium oxide, or a mixture thereof on a substrate made of glass or the like by a spatter or the like.

The recording method in this case will be described with reference to FIGS. 15 (a) to 15 (d).

When a pulsed voltage is applied with the transparent conductive layer 51 being negative and the electrode plate 59 being positive, and image exposure is carried out by the exposing member EM at the same time, as shown in FIG. The resistance of the bodies 52 and 54 decreases, and negative charges are injected from the transparent conductive layer 51 into the photoconductive layer 52, and further positive charges are injected into the photoconductive layer 54. Next, when the pulse voltage is removed after the exposure by the exposure member EM is stopped, each of the conductive layers contacting the exposed portion is adjusted so that the potential to the outside of the image storage body 4 becomes 0 as shown in FIG. 15 (b). Reverse charge is injected. Next, the electrode plate 59 which is in contact with the image storage body 4 is peeled off from the storage body 4, and the state shown in FIG. Even in this state, it can be sufficiently stored as an image storage body, but further the storage body 4 is entirely exposed by the LEDs 210 and 211 so that the electric charge is held only at both ends of the insulating layer as shown in FIG. 15 (d). It is also possible to save.

According to this recording method, since a brush, a roll or the like is used at the time of charging and discharging, there is no wasteful movement at the time of loading the film, and the mechanical structure can be simplified.

In the above-described embodiment, the type in which the charge is applied from the outside has been described, but the type in which the internally generated charge is used for recording will be described in detail below.

FIG. 16 shows an image storage body 4 using a piezoelectric material as a charge generation layer. The layer structure of the recording medium is such that a transparent conductive film 61, which is also transparent on the transparent base film 67, a transparent insulating film 62, a P-type photoconductor 63, a piezoelectric layer 68, an N-type photoconductor 64, and a transparent insulating film. 65 and a semiconductive layer 66 are laminated. The transparent base film 67 is the same as the above-mentioned base film 56, has sufficient translucency and strength / flexibility, and is preferably a polymer film such as polyethylene terephthalate or polyimide. The transparent conductive layer 61 is a layer containing indium oxide having a thickness of several tens to several hundreds of nm, or a small amount of tin oxide contained therein, and has sufficient translucency. Next, the transparent insulating films 62 and 65 are made of Si.
A high resistance material such as O ₂ or MgO is formed into a thin layer by vapor deposition or sputtering. The thickness of this insulating film is appropriately adjusted within a range in which sufficient translucency and insulation are maintained. Desirably, it is several hundred to several thousand Å.

Next, the semiconductive film 66 is a film such as glass or KCl.
A porous film of (potassium chloride) or the like, which has a resistance in the film surface direction higher than that in the film thickness direction and exhibits sufficient insulation, and the film thickness is preferably sufficiently thinner than the resolution width of the recorded image, For example, if the image has a resolution of 1000 lines / mm, the film thickness is several hundred pm.
~ It is desirable to be several tens of nm.

Next, the piezoelectric layer 68 is formed of Pb (Zr, Ti) O ₃ ceramics or B
It is a thin layer of aTiO ₃ ceramics, and has a sufficient light-transmitting property if the thickness is 10 μm or less. Also, in order to ensure sufficient piezoelectricity, it is sufficient if the thickness is 5000 Å or more. In addition, this piezoelectric layer is sufficiently poled in consideration of the charge generation direction after film formation. The P-type photoconductive layer 63 is a positive type photoconductor made of amorphous SeTe alloy or amorphous Si, and the N-type photoconductive layer 64 is a negative type photoconductor made of CdS, CdSe, ZnO, etc., both of which are vapor-deposited. The film is formed by the method. Further, the film thickness may be any thickness as long as it has sufficient translucency and photoelectrons are generated, and is preferably adjusted appropriately in the range of 1000 Å to several μm. Next, the recording method will be described in detail below. For the sake of simplicity, the base film 67 is omitted, and the base film 67 is shown in FIG.
An explanation will be given using (d). First, as shown in FIG. 17A, tension F is applied to the entire recording body 4 in the direction of arrow A, or pressure F is applied in the stacking direction of the recording bodies 4. At this time, the applied force F generates positive and negative charges in the direction pre-poled in the piezoelectric layer 68 as shown in the figure.
Next, in a dark place, the transparent conductive layer 61 is grounded or negative, and the semiconductive layer 66 is applied with a bias voltage by using a conductive brush or roll 57 so that the conductive layer 61 is negative and the semiconductive layer 66 is positive. After that, image exposure 58 is performed. At this time, the positive and negative charges on both ends of the piezoelectric layer 68 lower the resistance of the photoconductor in the portion exposed to the light, and the bias voltage causes an interface between each photoconductor layer and the insulating layer as shown in FIG. Move up to. Next, when the pressure applied to the recording medium is removed, the electric charge remaining on the piezoelectric layer of the non-exposed portion disappears, and the reverse electric charge is generated in the exposed portion, resulting in the state shown in FIG. The next conductive layers 61 and 66 are short-circuited to the ground by using a conductive brush or roll 57 'on the semi-conductive layer side, and the electric charges are held only in the above-mentioned light-exposed portions, and the same figure (d) is shown on the recording material. The electrostatic image shown in () is preserved, and the surface potential can be zero volt.

As described above, since recording is performed by the internally generated charges, the recording potential is applied to the entire film thickness of the storage body, and the surface potential can be made higher than that of other types. Further, since the photoconductor does not touch the electrodes, it is possible to prevent problems due to contact resistance and the like.

Next, as another embodiment, another example in which the image storage body is made of a piezoelectric material will be described in detail. Photoconductors such as CdS, CdSe, ZnO, and ZnTe are usually mixed with a binder and often used as a photoconductor. Even if the property is poor, it can be used as a piezoelectric optical semiconductor by poling strongly by a strong electric field. 18th
The figure shows a vertical sectional view of an image storage body 4 using this piezoelectric photoconductor. The structure of the image storage body 4 is a transparent base film 75.
Transparent conductive layer 74, N-type piezoelectric photoconductive layer 73, insulating layer 7 on top
2. A semiconductive layer 71 is laminated. Each layer will be described below. The base 73 is made of a material that has sufficient flexibility and translucency and is not cut by the tension during film loading. For example, polymer films such as polyethylene terephthalate and polyimide are preferable. Also,
In order to satisfy the above characteristics, the thickness of the film is preferably 10 to 50 μm for polyethylene terephthalate, and 5 to 50 μm for the polyimide film. Transparent conductive layer 74
Is tin oxide, indium oxide, or a material containing a small amount of tin oxide. This layer is formed by a known method such as sputtering, and preferably has a thickness of several tens to several hundreds of nm with a thickness that allows light transmission and sufficient conductivity.

The piezoelectric N-type photoconductor layer 73 is an N-type photoconductor such as CdS, CdSe, or ZnO formed by a known method such as a sputtering method shown in uSP4,363,711. The above monolayers of CdS and the like are laminated by RF sputtering in an external field of a frequency on the order of MHz. Further, the formed photosensitive layer is poled after the film formation so as to exhibit the first piezoelectricity in a desired direction in a strong DC electric field. In addition, the film is formed to a thickness such that a sufficient electron-hole pair is generated by receiving light, the insulation of the dark part is secured, and the internal diffusion of light can be ignored. For example, the range of 100 to several μm is desirable. Next, the insulating layer 72 is a highly insulating thin film such as SiO ₂ or MgO and is formed by a method such as sputtering. The thickness of the film is preferably several μm to several tens μm in order to have sufficient insulation. Next, the semiconductive film 71 is a film such as glass or KC.
A porous film such as l (potassium chloride) that has a higher resistance in the film surface direction than the film thickness direction and exhibits sufficient insulation, and the film thickness is preferably sufficiently thinner than the resolution width of the recorded image. ,
For example, if the image has a resolution of 1000 lines / mm, the film thickness is several hundred pm
~ It is desirable to be several tens of nm.

Next, FIG. 19 (a) -about the recording method to the image storage body 36.
This will be described using (d). For recording, see Fig. 19 (c)
An auxiliary electrode 80, which is formed by depositing a conductor such as tin oxide on a glass substrate 77, is used as shown in FIG. For recording, first, as shown in FIG. 7A, while pulling a force F on the image storage body 4 in the direction of the arrow, light is applied to the front surface by the LEDs 210 and 211, and then the light is blocked to eliminate the pressure. As a result, piezoelectric positive and negative charges are generated in the pre-poled direction as shown in FIG. Next, as shown in FIG. 19 (c), the auxiliary electrode 80 is brought into contact with the semiconductive layer 71 so that the conductive layer 76 is in contact with the conductive layer 76.
74 is short-circuited and dropped to the ground, and the exposed member EM of the first illustrated device
To expose a predetermined amount. This exposure lowers the resistance of the piezoelectric photoconductive layer 73 in the light-exposed portion and erases the accumulated charge in this portion. As shown in FIG. 6C, positive and negative charges are injected into the conductive layers 76 and 74 so that the surface potential of the accumulator 4 becomes zero in the portion not exposed to the light. Then, the positive charges injected into the conductive layer 76 are immediately transferred to the semiconductive layer 71.
Is injected into. In this state, the conductive layer 74 is grounded, the auxiliary electrode 80 is removed, and then the entire surface of the accumulator is again exposed by the LEDs 210 and 211, whereby the record holding state shown in FIG.

According to this embodiment, since the photosensitive member itself is of a type that generates electric charges, it is not necessary to have an external charging means, and the mechanism and process can be simplified.

Next, FIGS. 22 and 23 show in detail an embodiment in which a color image or the like can be stored in the image storage body 4 of the present invention, and are combined with the configuration of FIGS. Be done.

Fig. 22 (a) is a perspective view, and Fig. 22 (b) shows a cut end when cut by a plane including the straight line XY shown in Fig. 22 (a) and, for example, three optical axes 1101 to 1103. FIG. The same figure (b)
Also conceptually shows the positions of the optical system and the electron gun.

The image accumulator 4 shown in FIG.
Not only are multiple images lined up (ie, in the lengthwise direction of the film), but also in the direction perpendicular to that, that is, X
It is characterized in that a plurality of images are arranged also in the −Y direction. This is because the present invention enables very high density image storage, as will be described later. That is, for example, when accumulating images with a resolution of 1000 lines / mm, if a square or rectangular area with a side of 4 to 6 mm is set as one screen, it will be comparable to or exceed the negative film of silver halide photographs, for example. The resolution can be obtained.
Therefore, if the image is accumulated only in the film winding direction 60, the image accumulator 4 of the present invention has a thinner tape shape rather than a film shape. There is not much inconvenience that the image storage body 4 is in the form of a tape, but if the width of the storage body 4 is made wide so that a plurality of images can be arranged, a larger capacity of storage can be achieved, and the above-mentioned configuration is achieved. Thus, a high quality image recording system can be realized with a simple configuration. Alternatively, even with the same capacity, the length in the lengthwise direction can be reduced, and the number of windings on the winding shafts 41, 42 can be reduced. As a result, it is possible to suppress the occurrence of accidents such as charging due to radial stacking on the winding shaft. Also, by reducing the number of windings, the shaft diameter of the winding shaft can be increased, and even in that case the overall compactness is not lost, and the radius of curvature of the innermost film is increased, and it becomes a member of the image storage member. There are many advantages such as the ability to reduce such stress.

As shown in FIG. 22 (b), images 4001, 4001 ', 400 can be accumulated on the film for which such effects can be expected.
This can be achieved by changing the position of the optical system 11 corresponding to 1 ″.

That is, for example, the optical system 11 is parallel to the straight line XY (that is,
It is to move in the vertical direction in FIGS. 22 (a) and 22 (b). This is the illustrated drive mechanism, step motor MT,
A pinion G1 provided on this shaft and a rack G2 that meshes with the pinion G1 are provided, and the lens is fixed to an extension of the rack G2.

As another method, a configuration may be adopted in which the optical axis of the optical system 11 is swung with respect to the reference axis 1102, as shown in FIG. In this embodiment, an image 4001, which corresponds to the optical axes 1101 and 1103
Since the film surface is curved and held so that 4001 ″ does not cause aberration, the optical system 11 is simply
BM1 and BM2 need only be configured so that they are displaced in opposite directions.

In order to bend and hold the film in this way, for example, a frame for sandwiching the image storage body may be provided on both sides in the vicinity of the exposure section.

FIG. 23 shows an embodiment different from that of FIG. In this embodiment, independent optical systems 111, 112 and 113 are provided corresponding to the images 4001, 4001 ′ and 4001 ″. In the configuration of FIG. 22, the optical systems can be translated or swung. In the configuration shown in the figure, only one exposure member EM is required for the optical systems 111 to 113. Three optical systems are required. Although it is more disadvantageous than the configuration of Fig. 22, reliability is improved because the optical axis of each optical system is fixed.
It is not necessary to bend and hold the film surface as compared with the embodiment of FIG.

An image 4001 formed by the configuration shown in FIGS. 22 and 23 above
It goes without saying that a scanning means composed of one electron gun 23 is sufficient for reading out .about.4001 ".

FIG. 24 is a diagram when the configuration of FIG. 23 is applied to the storage of color images.

The configuration shown in FIG. 23 is the same as that shown in FIG. 23 in that a plurality of optical systems, especially three sets, are provided, but in addition to that, each optical system is provided with color filters F1 to F3 having different spectral characteristics. is there. In this case, it is sufficient to use R, G, B as the combination of color filters to be used, but other combinations may be used. Since the combination can be determined based on a known color signal processing method, the description thereof will be omitted here.

The images simultaneously recorded and accumulated as described above by using a plurality of optical systems equipped with color filters have three electron guns 231, 232, 23.
It is possible to read out simultaneously using 3 and this is also shown in the configuration of this figure. However, if the read time may be a little longer, it is possible to sequentially read using one electron gun as in FIG.

In this way, a plurality of images can be made incident simultaneously or sequentially in the direction orthogonal to the moving direction of the image storage body 4, so that a high-resolution color image can be easily obtained when colorization is intended.

In the embodiment shown in FIG. 24, filters F1 to
Although F3 is combined with each other, the three colors may be separated, for example, by combining a dichroic mirror and a color filter.

Further, as shown in FIGS. 22 and 23, when the color is not formed, the number of windings around the winding shaft of the image storage body can be reduced, and the apparatus can be made compact. In addition, the number of turns can be reduced, but the diameter of the shaft can be increased to reduce the stress on the image storage body.

Next, FIGS. 24 (a) to 24 (c) and FIGS. 25 (a) and 25 (b) show an embodiment in which the image accumulating member 4 is formed into a disk shape. Image storage 4
To form a storage layer.

Further, the disk-shaped image storage body 4 is rotationally driven about the axis MM 'by the motor MM. Motor MM is a vacuum container
It is hermetically sealed together with the electron gun 23 and the like in 102 and is connected to the connector 3 by a lead wire (not shown). The beam deflecting means and the like are not shown. Also, a plurality of images can be stored at different rotational positions on the disk by the rotational movement of the disk.

Furthermore, in this embodiment, a plurality of images 4001, 4001 ', 4001 "can be recorded along the direction orthogonal to the rotational movement direction, that is, the radial direction. Each image 4001, 4001', 40
01 ″ is the accumulator 4 due to the different optical axes 1101, 1102, 1103.
Incident on.

Further, as shown in FIG. 24 (b), the optical axes 1101 to 1103 may be sequentially formed by shifting the optical system as in the embodiment of FIG. 22 (b). As shown in FIG. 6C, it may be formed by fixedly providing three optical systems 111 to 113 separately in advance.

Further, FIGS. 25 (a) and 25 (b) realize colorization by utilizing the configuration shown in FIG.

FIG. 25 (a) shows the structure of FIG. 24 (b) in which color filters F1 to F3 are further provided in the incident optical path.
Are R, G, and B filters respectively, but may be a combination of filters of other colors. A light shielding mask OB is provided around the filters F1 to F3.

FIG. 24 (b) is a schematic configuration diagram including the reading by the electron beam. In the present embodiment, three electron guns 231 to 233 read RB images 4001 to 4003 at the same time. It goes without saying that one electron gun may sequentially read the images 4001 to 4003.

As described above, when the image accumulator 4 has a disk shape, it is not necessary to wind the accumulator, so that the accumulator itself can be prevented from being broken due to frictional electrification, and the electric signal in the accumulator can be prevented from being lost. Moreover, it has the feature that it is easy to obtain flatness. The twenty-fourth and twenty-fifth embodiments shown in FIGS.
It goes without saying that it is applicable to any of the configurations shown in FIG.

According to the present invention, since image recording and image reading can be performed independently and without changing the state, it becomes possible to record a high-density image with a device which is convenient for carrying, and the image recording system used so far. Could be greatly improved.

Moreover, according to the present invention, a large amount of image information can be stored with a relatively compact structure by effectively using an image storage body having a limited area, and unnecessary charging and colorization can be easily realized.
