摘要:
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.

摘要:
The laminated structure comprises: a plurality of thin plate members; and adhesive which bonds the plurality of thin plate members in layers, wherein: at least one of the plurality of thin plate members has at least one bonding surface to be bonded with a surface of another of the plurality of thin plate members with the adhesive; at least one groove is formed in a breadthways direction of the thin plate member on the bonding surface; and at least one of ends of the groove does not reach an edge of the thin plate member.
摘要:
The liquid filling method is for filling a liquid into a liquid discharge apparatus comprising a nozzle which discharges a droplet of the liquid, a pressure chamber which is in communication with the nozzle and is filled with the liquid to be discharged as the droplet through the nozzle, and a pressure generation device which generates pressure variation in the liquid inside the pressure chamber to cause the droplet to be discharged through the nozzle, and the method comprises the steps of: adjusting a contact angle of the liquid on an inner surface of the pressure chamber to be not more than an angle formed inside the pressure chamber by two mutually adjacent surfaces constituting the inner surface; and filling the liquid into the pressure chamber.
摘要:
The image forming apparatus includes: a recording head which has a plurality of recording elements; an intermediate transfer medium on which an image is recorded temporarily by the recording head while the intermediate transfer medium implements relative movement with respect to the recording head; an image defect determination device which is disposed on a downstream side of the recording head in terms of a direction of the relative movement of the intermediate transfer medium and which determines whether the image recorded on the intermediate transfer medium includes an image defect or not; a transfer device which is disposed on a downstream side of the image defect determination device in terms of the direction of the relative movement of the intermediate transfer medium and which transfers the image recorded on the intermediate transfer medium, to a recording medium; and an image correction device which creates correction data according to information about the image defect if the image defect determination device determines that the image recorded on the intermediate transfer medium includes the image defect, wherein, if the image defect determination device determines that the image recorded on the intermediate transfer medium includes the image defect, an image based on the correction data is recorded on the intermediate transfer medium by the recording head.
