As an ink supply device for a rotary letterpress printing machine, those described in Non-Patent Document 1 are known. Fig. 2 is a view showing an ink supply device for a rotary letterpress printing machine described in the above Non-Patent Document. In the ink supply device, the ink contained in the ink tank 10 is transported from the can roller n to the transfer roller 2, and the transfer roller 12 is transferred to a plurality of roller rows 13 to grind the ink, and the ink is inked. The plurality of ink fountain rollers 15 that are connected to the last of the plate 14 are transferred to the line portion of the relief plate 16 mounted on the outer periphery of the plate 14 to be inserted into the continuous paper between the plate and the pressure plate 17 Printing is performed on S. [Non-Public Literature] [Non-Patent Document 1] [Non-Patent Document 1] Watanabe Akio, "Introduction to Printing Press", Printing Society Press, July 1, 60, the first edition of the first brush, p38 [Invention] • [Problem to be Solved by the Invention] 1 <,,;', in the ink supply device of the above-described rotary type letterpress printing machine, the ink fountain roller that supplies ink to the relief 16 attached to the outer periphery of the magazine 14 η contacts the ink supply roller 18 on the upstream side in such a manner that the diameter is smaller than the outer diameter ' of the magazine 14 and the ink fountain roller 15 spans the two smaller diameters, and supplies ink from the ink supply roller 18 to the ink fountain roller 15 Therefore, it is not possible to supply sufficient ink to each ink fountain roller 149717.doc 201113157. Therefore, for example, in the case where the printing of the pattern A shown in FIG. 3 is performed on the continuous sheet S, since the transfer of the ink in the portions a and c is continuous, the portion of the ink displayed in the region b is Since the transfer is intermittent, even if ink is supplied from the plurality of ink supply rollers 18 to the outer circumference of the ink fountain roller 15, the ink film formed on the ink fountain roller 15 is thicker in the portion corresponding to the region b, and on the other hand, The portions corresponding to the regions a and c are thinned, so that the film thickness of the ink film in the axial direction of the ink fountain roller 15 is not uniform, and a difference in density occurs in the ink film. Since the difference in density of the ink film appears on the printed matter, there is a problem that a density difference called a ghost image is generated in the above-described pattern A. Further, in the above-described rotary letterpress printing machine, the plate and the plate having different diameters are replaced according to the printed matter, but when the plate is replaced, the new plate must be adjusted to be respectively associated with a plurality of ink fountain rollers and Pressure contact, so there is also the problem of adjusting the contact pressure. SUMMARY OF THE INVENTION A problem of the present invention is to provide a rotary letterpress printing machine which can obtain a good print without ghosting and can easily adjust the contact pressure when the plate is replaced. [Technical means for solving the problem] In order to solve the above problems, in the present invention, the ink squeezing device of the rotary letterpress printing machine is configured to send the ink contained in the ink tank from the can light to the ink transfer. Roller, from the transfer roller to a plurality of roller rows and smoothing by: j) 4» λ. v ^ ^ ~ ink transferred from the last ink fountain roller connected to the plate to the installation of the hole in the hole Xiao > Λ 凸 凸 而 在 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸 凸The ink supply roller whose outer diameter is set to be larger than ± the outer diameter of the plate is in contact with the outer circumference of the ink fountain roller. " making the complex number ^, so that the outer diameter of the ink fountain roller is larger than the outer diameter of the printing plate, thereby allowing a plurality of inks to be supplied to the relief printing plate which is in contact with the ink film of the ink fountain of the ink fountain, :于=: :::: The ink film forms a ghost image, and it can also form a uniform film thickness from the ink supply roller to the ink ice. Ink film. As a result, a good printed matter without ghosting can be known. Here, the ink supply is reported as a plating roller having a peripheral charge, and a is also used to supply the m to the axial reciprocating movement - the vibration of the fixed stroke is light, whereby the ink film on the outer circumference of the ink fountain roller can be made. The circumferential direction and the axial direction are inconsistent, so that the uniformity of the ink film on the outer circumference of the ink fountain roller can be further raised. [Effect of the Invention] As described above, in the present invention, the outer diameter of the ink fountain roller is made larger than the outer diameter of the magazine, whereby a plurality of ink supply rollers can be brought into contact with the outer circumference of the ink fountain roller, so that a plurality of inks can be obtained The supply newspapers supply the ink fountains with sufficient ink. Therefore, even if the ink film on the outer circumference of the ink fountain roller is a relief, and the ghost image is formed by the ink film, the ghost image can be reliably eliminated by the ink supplied from the plurality of ink supply rollers, thereby being able to be used in the ink fountain roller. An ink film having a uniform film thickness is formed on the outer periphery. Therefore, a good print without ghosting can be obtained. In addition, 'set the ink to 1' to 'replace' the plate with a different diameter. 'The replacement plate can only be contacted with the ink fountain and the pressure can be compared to the previous one. It is also easy to carry out the adjustment work by contacting the replaced plates with a plurality of ink fountain rollers and pressure rollers. [Embodiment] 〃° The following is an embodiment of the present invention based on the drawings. Further, in the drawing, as in the ink pad device of the prior rotary letterpress printing machine shown in FIG. 2, the ink contained in the ink tank is supplied from the can roller to the ink roller by::: Roller 1, However, in Fig. 1, the transfer roller 12 shown in Fig. 2 is omitted. _ Ink tank 1 〇, can roller to supply the ink to line 1 by forming the light line! The plurality of rolls are sequentially ground and supplied from the ink supply roller 2 to the last ink fountain roller 3. Further, the black bucket roller 3 is composed of a rubber roller. The ink supplied to the outer periphery of the ink fountain 3 is transferred to the relief 5 attached to the outer periphery of the magazine 4, and is transferred from the relief 5 to the continuous paper s inserted between the stamp 4 and the pressure 6. By the transfer of the ink, a specific pattern is continuously printed on the continuous sheet S. The ink fountain is set to one more than the three. The outer diameter of the ink fountain (6) is set to be larger than the outer diameter of the magazine 胴4. The above-described ink supply roller 2 for supplying ink to the ink fountain roller 3 is plural. The plurality of ink supply roller members include a recording roller having a bell coating on the outer periphery. The plurality of ink supply rollers 2 are reciprocally moved in the axial direction by the -direction-rotation-surface, and the ink is supplied to the outer periphery of the ink fountain roller 3. The supplied ink is prevented from being uniformly oriented in the circumferential direction and the axial direction by the rotation of the ink supply (10) and the movement in the axial direction, thereby forming a uniform film thickness ink on the outer periphery of the ink fountain 3 As described above, the outer diameter of the ink fountain roller 3 is made larger than the outer diameter of the magazine 4, whereby a plurality of ink supply rollers 2 can be brought into contact with the outer circumference of the ink fountain (1). Therefore, that is, 1497I7.doc 201113157, the ink film of the outer periphery of 'Kun 3 is transferred to the relief 5 on the plate 4, and the ink film is formed by the ink film other than the 亲 3, and the ink film can be fed from the plurality of ink supply rollers to the ink fountain roller. 3, a sufficient amount of ink which can eliminate the ghost image is supplied, so that an oil black film having a uniform film thickness is formed on the entire circumference of the ink fountain 1 in the axial direction. For the soil, the ink fountain roller 3 is set to one, whereby since the plate 4 is replaced with the plate 4 having a different diameter, the replacement plate 4 only needs to be in contact with the ink fountain roller 3 and the same. At 2 o'clock, the adjustment of the contact pressure with respect to the ink cartridge roller 3 and the plate 4 of the pressure roller 6 can be easily performed.
