摘要： A color imaging system for use as an electronic still camera, for example, includes a color separator for separating the optical image of a subject from a lens into a plurality of different color images, an optical shutter selectively openable for transmitting the optical image of the subject to the color separator, a photoconductive layer for converting the different color images into respective electric charge images, and an information recording medium for recording images corresponding to the electric charge images under an electric field developed between the photoconductive layer and the information recording medium. The timing with which the optical shutter is opened and the timing with which the electric field is generated by the power supply, are controlled by a control unit depending on imaging conditions selected by the user. The color imaging system also has an optical viewfinder for allowing the user to visually observe the optical image of the subject introduced by the lens.

摘要： A method of information conversion in which a recording medium is composed of a photoconductive member and a photo-modulation member both exhibiting a photoelectric effect and a dielectric mirror interposed therebetween, laminated to each other. An electro-magnetic radiation beam intensity-modulated with a serial information to be converted is radiated to the photoconductive member. The radiated beam is deflected straight along a surface of the photoconductive member to form a charge image composed of electric charges having an electric charge quantity corresponding to the information, as arranged in a straight line in a region on a border between the photoconductive member and dielectric mirror, corresponding to a region of the photoconductive member to which the beam is radiated. A two-dimensional bundle of electro-magnetic radiation beams of constant intensity and covering the region on the border is radiated to the recording medium at the photo-modulation member side thereof to take out a two-dimensional bundle of electro-magnetic radiation beams exhibiting intensity variation subjected to the charge image due to the photoelectric effect from the recording medium.

摘要： A recording apparatus comprises first electrode, color-separation filter, recording, carrier generation, carrier transport, and second electrode layers which are laminated in order of mention. The recording layer and carrier generation layer may be separated at a given space. The recording layer comprises carrier retaining layer or a photo-modulation layer. Light image from an object is projected on the carrier generation layer through the first electrode, color-separation, and recording layers via an object lens enters the carrier generation layer. Carrier generated in the carrier generation layer in response to the light image are transported to the second electrode in response to application of a given voltage between the first and second electrodes. Discharge caused by application of the given voltage transfers a latent carrier image to the recording layer. The first electrode, color-separation filter and recording layers may be used for recording medium. The carrier generation, the carrier transport, and second electrode layers may be used as a recording head.

摘要： An electromagnetic radiation beam scanning system for scanning an object with an electromagnetic radiation beam. The scanning system comprises first and second beam-narrowing devices which are arranged so as to have elongated light-transmission regions, respectively, and which are overlapped each other so that the light-transmission regions intersect each other. Each of the beam-narrowing devices includes a light modulation layer showing an electro-optic effect, first and second electrodes disposed so as to sandwich the light modulation layer, first and second polarizers disposed so as to sandwich the light modulation layer and a power source for applying voltages to the first and second electrodes. The light modulation layer combined with the polarizers forms the elongated light-transmission region in response to application of the voltages to the first and second electrodes due to the power source so as to produce a narrowed beam when a light beam is incident thereon. The position of each of the light-transmission regions in each of the first and second beam-narrowing devices is arranged to be movable in response to variation of at least one of the application voltages due to the power source.

摘要： There is provided an apparatus for reproducing a charge latent image prerecorded on a recording medium composed of at least a photo-modulation layer and a charge holding layer laminated thereto and holding said charge latent image. The apparatus has two electrodes interposing the recording medium therebetween. The electrodes are connected to each other and one of which is spaced from the recording medium. A reading light is allowed to permeate the photo-modulation layer. The apparatus also has a vibrator which vibrates one of the electrodes to modulate an electric field generated between the electrodes by the charge latent image prerecorded on the recording medium. The reading light is then electro-optically modulated to reproduce the charge latent image.

摘要： A method of electrophotographic printing is disclosed. A recording medium comprising a photoconductive member and photo-modulation member laminated to each other, both exhibiting a photoelectric effect and a sensitized member made of a chargeable photoconductive member are arranged so as to face each other. A first electro-magnetic radiation beam (abbreviated in a beam hereinafter) which is intensity-modulated with data to be recorded is radiated to the recording medium at the photoconductive member side thereof to record the data to the photo-modulation member with the photoelectric effect. A second beam of constant intensity is radiated to the recording medium to emit therefrom a third beam exhibiting intensity variation subjected to the recorded data. The sensitized member is exposed with the third beam to form thereon a charge image corresponding to the recorded data. Toner is stacked onto the sensitized member formed with the charge image to form thereon a toner image. The toner image is then transferred onto a printing paper, thus to perform repeated printing utilizing the data once recorded to the recording medium.

摘要： There is disclosed herein an image sensing device of an image pickup apparatus which produces an image signal corresponding to an optical image of an object taken through the image pickup apparatus. The image sensing device includes an photoconductive member responsive to the optical image on one surface thereof to produce an charge image corresponding to the optical image on the other surface under a predetermined electric field and a change holding member arranged so that an electrostatic latent image is formed on one surface thereof. The charge holding member is disposed to be opposed relation to the photoconductive member and first and second electrodes are respectively disposed on the photoconductive member and the charge holding member. Also included in the device is a voltage application circuit comprising a change-over switch and a power source so that a voltage of the power source is applicable to the first and second electrodes. The operation of the switch is controlled by a switch control unit so as to allow and interrupt the application of the voltage of the power source to the first and second electrodes. Discharging between the members is developed in response to application of the voltage thereto so that a charge image is formed on the charge holding member in correspondance with the charge image formed on the photoconductive member.
