Problems solved by technology

However, it is difficult to produce an ultraviolet-curable adhesive / ultraviolet-curable resin sheet containing a large amount of hard particles substantially uniformly, or as described above, there are cases where many hard particles are buried in the ultraviolet-curable adhesive / ultraviolet-curable resin sheet. Concern, it is difficult to improve the coefficient of friction of the friction coating

Embodiment Construction

[0050] Hereinafter, the best mode for carrying out the present invention will be described.

[0051] This embodiment is an example in which the present invention is applied to a paper feed roller for paper feed provided in an inkjet printer and a method of manufacturing the paper feed roller. Such as figure 1 As shown, the printer 1 is an inkjet printer, and the upper part of the main body shell 2 is provided with a moving space for the carriage 3. The carriage 3 is guided and supported by the carriage guide shaft 4, and can move back and forth left and right. The carriage 3 is moved by steps. The motor is driven by a synchronous belt and a pair of pulleys connected with the carriage 3 at both ends. For example, ink cartridges 7 a to 7 d of four colors are detachably attached to the carriage 3 . The paper 9 is fed from the tray 8, fed by the paper feed roller 10 and the pressing roller on the upper side thereof, and printed on the paper by the print head of the carriage 3 wh...

Abstract

A paper feed roller capable of assuring a rigidity and an accuracy and reducing a machining cost and a material cost and a method of manufacturing the roller, the paper feed roller comprising a hollow pipe-like member having a paper feed part for feeding paper formed thereon and a pair of shaft members coaxially fixed to both end parts of the pipe-like member, the pipe-like member further comprising a hollow steel pipe, a synthetic resin cover material for covering the outer peripheral surface of the steel pipe, and a synthetic resin friction coat layer containing hard particles formed on the outer peripheral surface of the cover material, wherein a steel pipe covered with the synthetic resin cover material can be used as the material of the pipe-like member.

Description

[0001] This application is a divisional application of the invention patent application with application number 02829290.1 ​​entitled "Paper Feed Roller and Its Manufacturing Method". technical field [0002] The invention relates to a paper feed roller of office automation equipment such as printers, fax machines, copiers and the like. Background technique [0003] In the past, in office automation equipment such as printers, facsimile machines, copiers, etc., the paper feed roller for paper feed has a paper feed part for paper feed and a pair of shaft parts at both ends. The surface is generally formed with a friction coating made of synthetic resin containing hard particles. [0004] When manufacturing the paper feed roller, a steel rod is cut, and shafts are formed at both ends, a plating protective film is formed on the outer surface, and a synthetic resin friction coating is formed on the outer peripheral surface of the paper feed part. , thus completing the fabricati...
