Abstract: PROBLEM TO BE SOLVED: To obtain a printer producing a high quality printed matter equivalent to that of offset print in which a different image can be printed every time by heating a liquid ink layer having viscoelasticity according to image information and bringing the ink layer into contact with an intermediate recording body having ink rejecting properties. SOLUTION: An ink image 6 formed on an intermediate recording body 1 is transferred onto a matter 8 to be printed, e.g. a paper, when it is pressed onto the intermediate recording body 1 by means of a transfer roller 7. The transfer roller 7 is disposed in parallel with an ink supply roller 3 and turned in the direction of an arrow C. Since the intermediate recording body 1 has ink rejecting properties, the ink image 6 is transferred from the intermediate recording body 1 onto the matter 8 to be printed at a transfer efficiency close to 100% when the temperature of liquid ink transferred to the intermediate recording body 1 is lowered and viscoelasticity is recovered. The ink image 6 being formed on the intermediate recording body 1 is not affected by the surface properties of the matter 8 to be printed and stabilized.

Abstract: PURPOSE:To obtain a photogravure printing press protecting a plastic gravure plate from a flaw and less susceptible to quality changes by placing an impression cylinder of a specific unit, and an impression cylinder and a transfer cylinder of an upper unit so that transfer may be made at the nearest contact point between the impression cylinder and the transfer cylinder of the upper unit. CONSTITUTION:Impression cylinders 11, 21, transfer cylinder 2, and a gripper 4 are placed in such a manner that allows printing paper transferred at the mearest contact point P1 between the impression cylinder 11 and the transfer cylinder 2 of Unit 1, at the transfer cylinder 2 between the impression cylinder 11 of Unit 1 and the impression cylinder 21 of Unit 2, to be transferred at the nearest contact point P2 between a cylinder 21 of Unit 2 and a transfer cylinder 2 of Unit 2 by the rotation of the transfer cylinder 2. If it is assumed that the transfer cylinder 2 and the impression cylinders 11, 12 have an equal diameter and that angle P1 O P2 formed at the three points: the nearest contact point P1, the shaft center of the transfer cylinder 2, O, and the nearest contact point P2, is theta, theta=180 deg. must be valid.

Abstract: PURPOSE:To provide a printing device having high resistance to scratches on a doctor blade by providing a grinding area on a part of a block making sheet placed around a rotatable plate cylinder. CONSTITUTION:A recess 2a is formed at a desired location in a block making region L1 of a block making sheet 2 by laser processing and a print sheet 4 is pressed against a print sheet region L2 having a size larger than the region L1 during the printing. A grinding element 2b is provided on the end of the sheet 2 at a point outside the region L2 and the element 2b is prepared by applying abrasives onto the sheet 2. The abrasives comprise particles having particle diameter of 0.1-1mum and the particle diameter may preferably be changed taking account of the material of a doctor blade 9, that is the degree of susceptivity to scratches. As a result, since the doctor blade is ground during the printing, it has high resistance to scratches.

Abstract: PURPOSE:To rapidly move recorded paper when a multi-color printing is conducted in a monochromatic printing device and to reduce a depth dimension of a device to obtain a sufficient space for providing an automatic plate loading part by a method wherein detachable paper supply and discharge cassettes of the same shape used as paper supply and discharge means are loaded on/ unloaded from a housing of the printing device. CONSTITUTION:A paper supply cassette 16 and a paper discharge cassette 17 are detachably provided on one face, e.g. a front face, of a housing 18. Printed paper 11 which has been fed from the paper supply cassette 16 through an impression cylinder 7 and a plate cylinder 4 is turned by paper discharge rollers 9a toward the same direction as the paper is supplied. Furthermore, the paper is discharged frontward to be stacked in the paper discharge cassette 17. Therefore, the printed paper 11 can be rapidly and easily removed when a multi-color printing is conducted in a monochromatic printing device, and the depth dimension of the printing device housing can be reduced.

Abstract: PURPOSE:To improve workability by providing a printing part which prints one surface of a printing sheet at a time and delivers the printing sheet to a sheet discharge mechanism in a state that the surface and back and the top and bottom of the sheet are turned over when the sheet is received from a sheet feeding mechanism. CONSTITUTION:When printing is started, printing sheets 49 are fed one by one from the top of a printing sheet bundle 50 to a printing part 25 by means of a feeding mechanism 15, and the printing sheet 49 on the one surface of which printing is applied is discharged onto a sheet discharge table 7 by means of a sheet discharge mechanism 20. In this case, the back and surface and the top and bottom of the printing sheet 49 when it is placed on a sheet feeding table 5 are turned over. When the some number of printing sheets 49, 49... is fed to the printing part 25 from a printing sheet bundle 50 on the sheet feeding table 5, a feed sheet position sensor 12 is turned OFF, a sheet feeding table motor 6 is run forward, and the sheet feeding table 5 is raised. When the sensor 12 is turned ON again, a motor 6 is stopped. When the some number of the printing sheets 49, 49... is discharged to a sheet discharging table 7 and a sheet discharge sensor 13 is turned ON, a motor 8 is reversed, the sheet discharging table 7 is lowered, and when the sensor 13 is turned OFF again, the sheet discharging table motor 8 is stopped.

Abstract: PURPOSE: To maintain the high contrast of a projected optical image by adhering the 1st conductive layer to one surface of a mesh-like insulating layer and 2nd conductive layer allowed to contact with a dielectric mirror film to the other surface and connecting the 2nd conductive layer to a transparent conductive film at a common potential.
CONSTITUTION: The 1st and 2nd conductive layers 18a, 18b are formed on both the surfaces of the mesh-like insulating layer 17. The 1st conductive layer 18a is arranged on the opposite side to a target 2 about the insulating layer 17 and a video signal is applied between a mesh-like electrode 8m of the 2nd glid 18 and the transparent conductive film 5. The 2nd glid 18 is arranged so that the 2nd conductive layer 18b is contacted against the dielectric mirror film 4, and the 2nd layer 18b is connected to the film 5 of the target 2. Even if a modulation voltage having large amplitude is applied, a crystal thin plate 3 is partially shielded because of the existence of the 2nd layer 18b having the same potential as that of the film 5 and the projected optical image can be maintained at a high contrast level without disturbing the electric field pattern.
