[Knowledge technology] In recent years, recording devices that can record information such as images and videos on recording media include electronic photocopiers, fax machines, laser printers, thermal transfer printers, and inkjet printers. Point-to-point printer. In such a recording apparatus, in order to transport a recording medium for recording information as a transported object to a necessary position, a transport mechanism having a transporting means capable of transporting the recording medium is required. As the conveying means, the conveying roller is often used because of its simple structure and low cost. In addition, as a transfer roller, a metal roller made of a metal is often used because of its excellent durability and roundness that affects the accuracy of the transfer. Fig. 10 shows an example of a conventional transfer roller made of metal. A conventional transfer roller 1 is a metal roller body 2 having a stepped cylindrical shape made of metal. The metal roller main body 2 is provided with protrusion forming portions 4 on the surface, i.e., both end portions in the axial direction of the outer peripheral surface, each of which has a plurality of minute protrusions 3 formed thereon. In addition, at the both ends of the metal roller body 2 in the axial direction, small-diameter journal portions 5 are formed in pairs on the left and right sides, respectively.

Description of the invention (2) The peripheral surface of the crimping roller 6 driven by rotation. Therefore, as shown in an enlarged view in Fig. 11, the roller 1 is driven to rotate to transport the roller 1, and the recording medium 7 is sandwiched between the roller 1 and the pressure roller 6 and transported. At this time, the conveyance roller 1 secures the catchability, conveyability, and conveyance accuracy of the recording medium 7 when the recording medium 7 is conveyed by inserting the leading ends of the plurality of minute protrusions 3 on the surface of the recording medium 7. In addition, as the method of forming the microprotrusions 3, there are a punching process method in which a tool punch is made to collide against the outer peripheral surface of the metal roller body 2, and an etching process in which a concave and convex portion is formed on the surface of the metal roller body 2. [Problems to be Solved by the Invention] In recent years, in recording devices, as recording media 7 for recording information such as images or videos, not only regular paper, thick paper, and postcards, but also polyester, polyparaphenylene Various materials, such as resin films such as ethylene glycol diformate, and materials coated with resin on the surface of paper-based materials. Further, in recent years, with the high definition and colorization of recording devices, higher requirements have been placed on the accuracy of their transfer. However, the above-mentioned conventional transfer roller 1 has a problem in that the uneven contact pressure of the crimping roller 6 and the type of the recording medium 7 cause different transfer accuracy. In the past, the conveying roller 1 has repeatedly conveyed the recording medium 7 and reversely conveyed it. In particular, it is necessary to form a color image using at least three primary colors of overlapping γ (yellow), M (magenta), and (: (cyan)). It is more obvious in the recording device. In other words, in the previous conveying roller 1, the contact of the crimping roller 6 with this paper is applicable to China National Standards (CNS) A4 regulations (210 × 297 mm) -5- " ^ I (Please read the precautions on the back before filling out this page}-Order P. Printed by the Employees' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 553834 A7 B7 V. Description of the invention (3) When the pressure is uneven, the small protrusions 3 are embedded The embedded amount of the recording medium 7 changes. For example, the contact pressure is deeper and the contact pressure is smaller. The embedded amount is different depending on the type of the recording medium 7. For example, a predetermined paper is used. The soft recording medium 7 is deeper, and the hard recording medium 7 such as resin is shallower. Therefore, the amount of conveyance of the recording medium 7 may change according to the change in the amount of embedding. As the aging time changes caused by the increase of the time, the contact pressure of the crimping roller 6 becomes smaller, and as the contact pressure becomes smaller, the embedded amount of the microprotrusions 3 changes, and the conveyance amount of the recording medium 7 also changes. Therefore, there is a need for a transfer roller that can easily obtain high accuracy for a long period of time. As a conventional transfer roller, although it has been proposed to have two types of heights: a micro protrusion having a high height and a micro protrusion having a low height. The structure of the microprojections, but in this case, the tips of the microprotrusions of two heights are respectively formed into a pointed shape, and the two microprojections are respectively embedded on the surface of the recording medium, which results in uneven contact pressure and the type of the recording medium. In view of the above, an object of the present invention is to provide a transfer roller that can easily obtain a high accuracy for a long period of time. [Means for solving the problem] In order to achieve the above The object of the present invention is that the transfer roller of the present invention is characterized in that the plurality of microprotrusions are microprotrusions having a high height and There are two types of micro-protrusions with lower degrees. The tops of the micro-protrusions with lower height are formed flat (please read the precautions on the back before filling out this page). Printed on paper.

Invention Description (4). By adopting this structure, when transporting goods , The flat part of the top of the low-profile microprotrusions supports the conveyed material without being embedded in the conveyed material, so only the tops of the high-profile microprotrusions are embedded in the transport material, and the embedded quantity and the contact pressure are uneven. Regardless of the type of conveyed material, it is kept constant for a long time. Therefore, it is easy to obtain high conveyance accuracy for a long time. [Inventive embodiment] The following describes the embodiment of the present invention with reference to the drawings. Fig. 1 is a view showing an embodiment in which the transfer roller of the present invention is applied to a paper feed roller as a transfer means of a recording medium of a recording device. As shown in Fig. 1, the conveying roller 11 of the present invention has a metal roller body 12 formed of a metal material such as stainless steel and having a stepped cylindrical body with a small diameter at both ends. On the both sides of the metal roller body 12 in the axial direction of the outer peripheral surface formed with a large diameter, there are provided protrusion forming portions 14 formed with a plurality of minute protrusions 13 which are simplified and exaggerated as shown in FIG. 1. , 14. The positions of these projection forming portions 14, 14 are located opposite to the pressure contact rollers 21 indicated by broken lines in the first figure. The lengths of the protrusion forming portions 14, 14 in the left-right direction in the first figure in the axial direction of the metal roller body 12 may be formed to be slightly longer than the length of the crimping roller 21, or may be slightly shorter. A pair of left and right journal portions 15 are rotatably supported by small diameter portions provided at both ends of the metal roller main body 12. In addition, the shape of the metal roller body 12 is not limited to a stepped cylindrical shape, but can be changed from a simple cylindrical shape according to the needs of the design.

Description of the invention (6) The trapezoidal low upright plane 13La is formed, and the top 13Lb is formed flat. The top portion 13Lb of the low protrusion 13L is not embedded in the surface of the recording medium 17 in a linear or surface contact manner during conveyance of the recording medium 17, but serves as a support. Therefore, the low protrusions 13L are arranged in the low protrusion forming portions 14L so that the respective low standing planes 13La face the rotation direction of the conveying roller 11 and are arranged at substantially equal intervals in the circumferential direction, and these low protrusions 13L are aligned in a row in the circumferential direction. A plurality of columns are arranged in the axial direction. The shape of the top portion 13Lb may be a flat surface extending in the rotation direction of the transport roller 11. The minute protrusions 13 in this embodiment will be described. The height Hh of the high protrusion 1 3H is preferably in a range of 0.02 to 0.2 mm, and a range of 0.03 to 0.1 mm is more preferable, and a leg range of 0.04 to 0.08 is more preferable. If the height Hh is lower than this range, it becomes difficult for the tip of the high protrusion 13H to fit into the recording medium 17, and an appropriate frictional force cannot be obtained when the recording medium 17 is transported. As a result, the recording medium 17 cannot be captured and transported. On the other hand, if the height Hh is higher than this range, the amount of penetration of the high protrusions 13H into the recording medium 17 is too large, leaving traces of the high protrusions 13H on the printing surface of the recording medium 17. The local Lh of the low protrusion 13L is preferably in the range of 0. 008 to 0.15 nun. The range of 0.01 to Ό · 08 mm is more preferable, and the range of 0.02 to 0.05 mm is more preferable. If the height Lh is lower than this range, traces of high protrusions 13H remain on the printing surface of the recording medium 17. On the other hand, if the height Lh is higher than this range, it is difficult for the tip of the high protrusion 13H to fit into the recording medium 17, and an appropriate frictional force cannot be obtained when the recording medium 17 is transported. As a result, the recording medium 17 cannot be captured and transported.

Description of the invention (7) As shown in the enlarged front view in Figure 6, the difference between the heights Hh and Lh of the high protrusion 13H and the low protrusion 13L is also exaggerated. It is the height difference Δh (Ah = Hh ~ Lh). When the diameter of the conveying roller 11 is set to 4 ~ 30mm, it is preferably in the range of 0.007 ~ 0.05 mm, preferably in the range of 0.01 ~ 0.04 mm, and most preferably 0.02 ~ 0.03 gives range. If the height difference Δh is smaller than this range, it is difficult for the tip of the high protrusion 13H to fit into the recording medium 17, and an appropriate frictional force cannot be obtained when the recording medium 17 is transported. As a result, the recording medium 17 cannot be captured and transported. On the other hand, if the height difference Δh is larger than this range, the high protrusion 13H penetrates into the recording medium 17 deeply, and a trace of the high protrusion 13 is left on the printing surface of the recording medium 17. The included angles Η 0 and L 0 between the high standing plane 13 Ha of the high protrusion 13 and the low standing plane 13 La of the low protrusion 13L and the tangent to the outer peripheral surface of the metal roller body 12 shown in FIGS. 3 and 5 are respectively A range of 90 to 140 ° is preferred, a range of 100 to 125 ° is preferred, and a range of 105 to 120 ° is most preferred. If Η0 and L0 are smaller than this range, the top 13Lb of the low protrusion 13L will be easily embedded in the recording medium 17, and the top 13Hb of the high protrusion 13H will penetrate deeply into the recording medium 17, and on the printing surface of the recording medium 17, Traces of the high protrusions 13 are left. On the other hand, if Η β, L (9 is larger than this range, it is difficult for the top 13Hb of the high protrusion 13 嵌入 to be embedded in the recording medium 17, and an appropriate frictional force cannot be obtained when the recording medium 17 is transported. As a result, the recording medium 17 cannot be captured and transported.

Further, in this embodiment, two rows of minute protrusions 13 in the axial direction of the protrusion forming portion 14 can be formed in one press working. After finishing the processing of this row, the metal roller main body 12 is rotated by a predetermined angle, and then processing of the next row is performed. Therefore, after one round of processing, the transfer roller 11 having the required minute protrusions 22 formed can be obtained. When the transfer roller 11 is used for a recording device for repeatedly transferring or reversing the recording medium 17, the metal roller main body 12 is sandwiched and the two punches 26 are arranged so as to face each other so that their teeth 29a are opposite to each other. At the same time, the positions of the teeth 29a of the two punches 26 are moved to the axial direction of the metal roller body 12 at the same time, and the micro-projections 1 3 facing the conveying direction of the recording medium 17 and the recording medium 17 can be processed at the same time. The small protrusions 1 3 in the opposite direction to the conveying direction. As the method for forming the microprotrusions 13, high protrusions 13H may be formed on the outer peripheral surface of the metal roller body 12, and the top Hb of some of these high protrusions 13H may be removed by a machine tool such as a lathe or a grinder to form low protrusions. 13L. In addition, the surface of the metal roller body 12 can also be subjected to electrical discharge machining and etching to form high protrusions 1 3H and low protrusions.

At this time, as shown in FIG. 9, the plurality of minute protrusions 13 of the transport roller 11 of this embodiment are flatly formed at the front end of the low protrusions 13L, that is, the top Lb, so the low protrusions 13L are tightly pressed to record. The load of the medium 17 is not concentrated at one point and is relatively dispersed. As a result, the front end of the low protrusion 13L, that is, the top Lb, is not embedded on the surface of the recording medium 17 and supports the recording medium 17. Therefore, only the tip of the high protrusion 13H, that is, the pointed top Hb, is embedded in the recording medium 17, and even if the contact pressure of the crimping roller 21 is large, the amount of insertion is determined by the height Hh of the high protrusion 13H and the low protrusion 13L, The level of the difference in Lh is kept constant. That is to say, according to the conveying roller 11 of this embodiment, the Chinese paper standard (CN5) A4 specification (210X297 is _ 16- 了 _ 16- 丨 丨 _ _ _ .. .. _ _ _. ; (Please read the notes on the back before filling this page) 553834 A7 B7 V. Description of the invention (14) (Please read the notes on the back before filling this page> When recording media 17, consider the time The reduction of the contact pressure is reinforced in advance, so that the insertion amount of the front end of the high protrusion 13H into the recording medium 17 can be kept constant without being affected by the unevenness of the contact pressure and the type of the recording medium. With the plurality of minute protrusions 13 of the conveying roller 11 of this embodiment, it is possible to ensure the capture property, conveyability, and conveyance accuracy when the recording medium 17 is clamped and conveyed.
