9 and more specifically the one shown in FIG. 3 of the present specification was known. In this type of device, in FIG.
It is necessary to secure positional accuracy in the axial direction between the characters 6a and 6b and the large diameter portion 9a of the ink roller body 9 and to prevent the characters 6b and the large diameter portion 9a from contacting each other. This is a necessary condition for preventing color mixture of ink.

混色がおきるという極めて重大な欠点があった。However, in the above-mentioned prior art, the positional relationship between the shaft 7 of the printing drum 5 and the ink roller shaft 4 can be ensured with accuracy through the contact member 8.
Since the surface 4a of the ink roller shaft 4 is flat, slippage easily occurs between the ink roller shaft 4 and the ink roller body 9, and when slippage occurs in the axial direction, as a result, the characters 6a and 6b and the ink roller body 9 are formed. The positional relationship in the axial direction with the large diameter portion 9a of 1 will change. Therefore, the contact between the character 6a and the large-diameter portion 9a becomes incomplete, or the character 6b and the large-diameter portion 9a come into contact with each other, resulting in a very serious defect that the ink is insufficiently applied or the ink is mixed. was there.

Is an ink roller body, which is made of a material such as rubber having a plurality of fine pores and is impregnated with ink. The outer peripheral portion of the ink roller body 1 has a large diameter portion 1a and a small diameter portion 1a.
b has a shape in which they are alternately arranged side by side, and like the conventional example shown in FIG. 3, the large-diameter portion 1a is in pressure contact with the type 6a,
The character 6b and the small diameter portion 1b are not in contact with each other.
Therefore, the ink with which the ink roller body 1 is impregnated has the type character 6a.
It is applied only to the type 6 and not the type 6b. JP-A-6
No. 0-141579, by providing another ink roller body having a shape in which the positions of the large diameter portion and the small diameter portion are interchanged, and impregnating each ink roller body with ink of a different color, Ink of different colors can be applied alternately every other digit, and a two-color printer becomes possible. Reference numeral 2 denotes an ink roller shaft which penetrates the ink roller body 1. The ink roller shaft 2 is formed with a plurality of vertical holes 2b in the axial direction. The ink roller body 1 is provided with a through hole 1c at a position facing the vertical hole 2b of the ink roller shaft 2, but this is provided only on one side in the cross section shown in FIG. It is installed on the other side, but not on the other side. Further, the pin 3 press-fitted into the vertical hole 2b of the ink roller shaft 2 penetrates the ink roller shaft 2, and one end 3a thereof is embedded in the ink roller body 1. For this reason, the ink roller shaft 2 and the ink roller body 1 are connected and fixed to each other via the pin 3, and axial slippage between the ink roller shaft 2 and the ink roller body 1 is completely prevented.

完了する。In order to assemble the ink application roller of this embodiment, first, the ink roller shaft 2 is inserted into the ink roller body 1, and the vertical hole 2b of the ink roller shaft 2 and the through hole 1c of the ink roller body 1 face each other. Let At this time, since the diameter of the through hole 1c of the ink roller body 1 is larger than the diameter of the vertical hole 2b of the ink roller shaft 2, it is possible to easily perform the visual alignment, and the alignment accuracy is not so required. Not Next, the pin 3 is connected to the through hole 1 of the ink roller body 1.
Press into the vertical hole of the ink roller shaft 2 from the side of c. Also at this time, since the vertical hole 2b of the ink roller shaft 2 can be visually recognized through the through hole 1c of the ink roller body 1,
Good insertability of pin 3. Then, the one end 3a of the pin 3 is inserted until it is securely embedded in the ink roller body 1, and the assembly is completed.

問題点を解決できるものである。As described above, according to the present invention, the ink roller body is fixed to the ink roller shaft by the pin,
Even if an abnormal external force is applied to the ink roller body, slippage does not occur between the ink roller body and the ink roller shaft, so it is possible to reliably ensure the axial accuracy of the large diameter portion of the ink roller body and the type. it can. Therefore, in a printer using an ink application roller, it is possible to prevent insufficient application of ink and color mixing of ink, and it is possible to solve a fatal problem as a printer.
