| 20100206191 | TRANSPORT ROLLER, TRANSPORT UNIT, AND PRINTING APPARATUS - A transport roller includes: a roller body of which a pair of end surfaces face each other by a press work so as to be in a cylindrical shape; and a high friction layer which contains inorganic particles and is provided on a surface of the roller body. Here, the roller body is provided with a joining portion which is formed by separating the pair of end surfaces. In addition, an average particle diameter of the inorganic particle is equal to or less than a distance between the pair of the end surfaces of the roller body on an outer peripheral surface side thereof. | 08-19-2010 |
| 20100206698 | CYLINDRICAL SHAFT, TRANSPORT ROLLER, TRANSPORT UNIT, AND PRINTING APPARATUS - A cylindrical shaft is provided of which a pair of ends are formed in a cylindrical shape by a press work so as to form a joining portion therebetween. Here, the joining portion includes: a central linear section which is provided on a center portion in an axis direction of the cylindrical shaft and is formed in a linear shape to be parallel to the axis direction of the cylindrical shaft; and a folded section which includes a plurality of intersections which are provided on both ends of the center portion and are disposed so as to be extended in a direction perpendicular to the axis direction of the cylindrical shaft, and a connection linear section which connects ends of a pair of the adjacent intersections. In addition, the connection linear section is constituted by a first linear section which connects ends on one side of the pair of the intersections and a second linear section which connects ends on the other side of the pair of the intersections and formed shorter than the first linear section. In addition, a distance between the pair of the ends of the center portion is longer than a distance between the pair of the ends of the second linear section. | 08-19-2010 |
| 20100209168 | TRANSPORT ROLLER, TRANSPORT UNIT, AND PRINTING APPARATUS - A transport roller includes: a roller body of which a pair of end surfaces face each other by a press work so as to be in a cylindrical shape; and a high friction layer which contains inorganic particles and is provided on a surface of the roller body. Here, the roller body is provided with a joining portion which is formed by separating the pair of end surfaces. In addition, an average particle diameter of the inorganic particle is larger than a distance between the pair of the end surfaces of the roller body on an outer peripheral surface side thereof. | 08-19-2010 |
| 20100209170 | CYLINDRICAL SHAFT, TRANSPORT ROLLER, TRANSPORT UNIT AND PRINTING APPARATUS - A cylindrical shaft which is formed in a cylindrical shape by pressing process in a state in which a pair of ends are opposite to each other is disclosed. A joint is formed between the pair of ends, and includes a plurality of intersection portions extending in a direction intersecting with an axial direction of the cylindrical shaft, a first straight portion connecting the ends of one side each of the pair of adjacent intersection portions, and a second straight portion connecting the ends of the other sides of the pair of adjacent intersection portions and being shorter than the first straight portion. A distance between the pair of ends at the first straight portion is shorter than a distance between the pair of ends at the second straight portion. | 08-19-2010 |
| 20110079952 | PRINTING APPARATUS - A printing apparatus includes a transporting roller formed of a metal plate bent into a cylindrical shape. The transporting roller has a first driving member that transmits a rotational driving force to the transporting roller, and a second driving member that transmits the rotational driving force transmitted thereto to a processing unit that performs printing-related processing. The first and second driving members are provided on one end side of a transporting area where recording media are transported. | 04-07-2011 |
