摘要： PROBLEM TO BE SOLVED: To provide a visible image recording device, which can obtain high picture quality, shorten reloading time, and consume no recording material. SOLUTION: By conveying recording medium 1 on a conveying passage 5, the recorded information of the previous image is real from the magnetically record part of the medium with a read head 6 so as to locate a region to erase in the visible image recorded part of the recorded medium 1 on the basis of the read information. The position of a heat generating part 10 on a thermally erasing roller 8 is detected with a heat generating part sensor 11 so as to determine the rotating timing of the thermally erasing roller 8 for coinciding the heat generating part 10 with the region to erase of the recorded medium 1. When the recorded medium 1 is detected with a position sensor 13, the counting of the timing of the action after the detection is started so as to rotate the thermally erasing roller 8 by the predetermined timing and, at the same time, the heat generating action of the heat generating part 10 is also started in order to erase the previous image of the recorded medium 1, After that, another visible image is recorded with a thermal head 14.

摘要： PURPOSE:To apply multi-value (multi-gradation) recording to a rewritable recording medium by recording a recording image so that the entire surface of the image becomes saturated density and by repeatedly performing imperfect erasure by the number of times corresponding to the density gradation data of the image. CONSTITUTION:A recording medium capable of recording an image by heating the recording medium to a first temp. region capable of erasing the image by heating the recording medium to a second temp. region lower than the first temp. region, and capable of imperefectly erasing the image by heating the recording medium to a third temp. region lower than the first temp. region is used. A recording image is recorded so that the entire surface thereof becomes saturated density regardless of density gradation data by heating the recording medium to the first temp. region and the imperfect erasure of the image by heating the recording medium to the third temp. region is repeated the number of times corresponding to the density gradation data of the image. As a result, multi-value (multi-gradation) recording is enabled with respect to a rewritable recording medium.

摘要： PURPOSE:To provide a recording medium and a visible recording method in which alteration, falsification and forgery are hard to perform and easier to find out, if any, than in the medium and the method heretofore available, and also the life can be longer. CONSTITUTION:A substrate layer 2 for improving the bond properties using a first recording layer 3, the first recording layer 3 for a color developing by heat and recording a visible image, a transparent light/heat conversion layer 4 for converting the emission of light energy to heat energy, a transparent intermediate layer 5 for preventing the transmission of heat converted in the light/heat conversion layer 4 to a second recording layer 6, a second recording layer 6 for developing color from the transparent state by heat and a protective layer 7 are laminate formed successively on one surface of a plate-shaped substrate 1. Light energy is converted to heat energy on a section to which the light of the light/heat conversion layer 4 is emitted by emitting partial light energy to an image pattern from the protective layer 7 side by means of a recording device using laser beam and the converted energy is transmitted to the first recording layer 3 to develop color only on the first recording layer 3 and recording a visible image.

摘要： PURPOSE:To eliminate stably a visible image of a recording medium by a method wherein a device to be driven by a plurality of electrification pulse rows, which are generated within an image dot forming cycle of a recording unit of a visible image and has pulse cycles different from each other, is provided. CONSTITUTION:Pulse data for formation of an electrification pulse row recording/eliminating a visible image being stored within a driving pullse data ROM 18 is transferred to a driving pulse forming part 19 from the driving pulse data ROM 18. With this construction, the electrification pulse row for driving a thermal head 21 is formed and sent to a thermal head driving part 20. In the thermal head driving part 20, since an original image data, a corrected recording/eliminating energy data and the formed electrification pulse row are supplied respectively, they are converted into signals driving the thermal head 21 and supplied to a thermal head 26. The thermal head 21 performs recording/eliminating actions of the visible image in accordance with the image data.

摘要： PURPOSE:To provide a recording apparatus capable of certainly recording or erasing a visible image even under high temp. environment and capable of always obtaining a clear recording image. CONSTITUTION:The recording or erasure of a visible image is performed with respect to a recording medium 1 opacified or transparentized by the control of heat energy to repeatedly record or erase a visible image using a thermal head 8. A Peltier element 10 is provided on the downstream side of the thermal head 8 as a cooling means and controlled in its driving by a Peltier element control circuit 11. The Peltier element control circuit 11 compares the ambient temp. inputted from a temp. sensor 12 with set temp. and, when the ambient temp. is high, the Peltier element 10 is driven to cool the recording medium 1 having a visible image recorded by the thermal head 8.

摘要： PURPOSE:To achieve light image-electrostatic image conversion without needing a precharge which accompanies ozone generation and to attain a chargeless electrophotographic process by employing an electrostatic latent image forming body which converts a light image to an electrostatic image without supplying charges from outside. CONSTITUTION:A developing unit 2, a transfer roller 3 which transfers a toner image on the electrostatic latent image forming body 1 onto a sheet, and a cleaner 4 which cleans the surface of the electrostatic latent image forming body 1 are disposed around the electrostatic latent image forming body 1. The electrostatic latent image forming body 1 is provided in such a manner that photoelectric conversion bodies composed of photoconductive elements and capacitor elements are made to correspond to the prescribed image elements, one for each, and extend in two-dimensional. In the electrostatic latent image forming body 1, potential is generated in light-transmissive electrode corresponding to the image element, therefore the uniform potential matching the size of the image element is generated and image element formation free of irregularities in pitch in the main scanning and subscanning can be achieved. By applying the electrostatic latent image body to the conventional electronic process as a substitute for the conventional photosensitive body, the chargeless electrophotographic process can be achieved.

摘要： PURPOSE:To certainly perform recording and erasing of data on a recording medium having first and second recording parts by a method wherein recording information on the second recording part of the recording medium is read out, and recording/erasing energy is selectively given to the first recording part based on the result of reading. CONSTITUTION:In the case a money amount subtractive type card 10 on which visual images can be recorded and erased is processed by a recording medium processor, the card 10 inserted into a card slot 20 is carried by transfer rollers, etc., and the recorded information is read by a reading head 22. When the card 10 inserted is valid, the usage historical data on the magnetic recording layer of the card 10 are updated written by a writing head 23. Then, a thermal recording part 24 of the thermal head records a new visual image on the oldest visual image part in a margin of an indicating part of the card 10 based on the usage historical data that have been read by a Judgment part previously. At this time, recording/erasing energy for recording or erasing the visual image is selectively given to perform recording or erasing.
