  • Patent number: 8011298
    Abstract: In an ink supply method and system and an ink container where the ink is automatically supplied in the stencil printing, to permit suitable detection of empty of the ink container even if the kind of ink which has not been set is employed. A parameter representing an inkless time corresponding to the kind of ink (viscosity of ink) is stored in the storage means (8) provided on the ink container (10), the parameter is read out from the storage means (8) and the inkless time is set on the basis of the parameter, whereby it is recognized that the ink container is exhausted when the time for which the ink in the ink fountain (2) is not detected by an ink amount detecting means (40) becomes longer than the inkless time.

  • Patent number: 7843983
    Abstract: In an element wherein a plurality of ridges (16, 36) are arranged in parallel, supports (17, 37) are formed to sandwich each of the ridges (16, 36). More specifically, on an outer side of the ridge (16) in the element, the first support (17a) is formed, and on an inner side in the element, the second support (17b) is formed. On an outer side of the ridge (36) in the element, the first support (37a) is formed, and on an inner side in the element, the second support (37b) is formed. Thus, even when a resist is applied on an element surface and spin-coating is performed at the time of manufacturing the element, the resist on the inner side than the ridges (16, 36) in the element can be prevented from flowing into a groove between the ridges to a certain extent by means of the second supports (17b, 37b), and a resist film thickness on the inner sides of the ridges (16, 36) in the element can be prevented from being considerably small compared with that on the outer sides in the element.

  • Patent number: 7819056
    Abstract: In a stencil printing method where a plurality of kinds of ink containers filled with ink of different colors are installed in a system body of a stencil printer and the ink in the ink container is supplied to a printing drum to carry out stencil printing, to easily set color information of the printing drum for determining whether the color information of the ink container conforms to the printing drum without necessity of operator's input. The color information stored in the storage means (9) of the ink container (10) installed in the system body (2) of the stencil printer is read out to a color information setting means (65), and at the same time, the color information setting means (65) confirms whether the color information has been already stored in the storage means (8) of the printing drum (31).

  • Publication number: 20100124424
    Abstract: In a duplex printer, when it is determined that a paper jam occurs only in the first transport path that is a path upstream of a sheet stacking unit among the first and second transport paths along a feeding direction of papers (the second transport path is a path downstream of the sheet stacking unit), operations of a sheet feed unit, a first printing unit for printing on one side of papers and an intermediate sheet transport unit that are located along the first transport path, are stopped. Then, all papers stacked on the sheet stacking unit are fed out and a second printing unit prints on another side of the fed-out papers. The papers with their both sides are printed are ejected by a sheet ejection unit. According to the duplex printer, it can be prevented that papers are wasted needlessly.

  • Publication number: 20060109289
    Abstract: In an ink residue calculating method where the ink residue is calculated by obtaining ink discharge discharged from an ink container on the basis of the number of rotations of a drive motor of an ink supply pump which sucks ink from the ink container and discharges the same and cumulatively subtracting the ink discharge discharged from the ink container from the total ink volume accommodated in the ink container, the ink residue is accurately calculated even if the kind of ink changes. The kind data of the ink is obtained by reading out from the storage means (5) of the ink container (4), the ink discharge of the ink supply pump per unit rotation of the drive motor for standard ink is corrected on the basis of the kind of the ink obtained by the ink residue calculating means (22), and the ink residue is calculated by cumulatively subtracting the value obtained by multiplying the corrected ink discharge by the working time from the total ink volume accommodated in the ink container (4).
