摘要:
An object of the invention is to obtain a high-quality image by reading an image of an electronic paper with high accuracy. When optically copying the electronic paper, a controller reads out display characteristics such as a reading resolution and a reading light quantity from a display characteristic memory of the electronic paper. The controller performs optical copying processing after setting optimal conditions on the basis of the display characteristics which have been read out from the display characteristic memory.

Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.

The inkjet head comprises: a nozzle which discharges droplets of ink through an ink discharge port to perform recording onto a recording medium, the ink being supplied through a supply duct, at least partial cross section of the nozzle on a side of the ink discharge port broadening toward the ink discharge port; and a device which moves a position of a boundary surface of the ink between a first boundary surface keeping position inside the nozzle at which the boundary surface of the ink is kept for recording and a second boundary surface keeping position inside the nozzle at which the boundary surface of the ink is kept for cleaning the nozzle under pressure less than or equal to ink discharging pressure, wherein fouling around the nozzle is collected by moving the position of the boundary surface of the ink between the first boundary surface keeping position and the second boundary surface keeping position.

A holding stand is constituted by a carrying case for holding sheets of electronic paper and a base for uprightly supporting the carrying case that is substantially vertical. From the holding stand, two page fields, each expressing the number of pages of sheets of electronic paper to be displayed and position page field expressing a current page position of electronic paper and incremented on each of the sheets, are added to image data, and the image data is output to the sheets of electronic paper. In each sheets, when the two page fields coincide with each other in comparison between the two page fields, an image based on the image data is displayed in a display region. When the two page fields are different from each other, the position page field is incremented by one, and the position page field is transmitted to the next electronic paper.
