Abstract: A medium transport direction switching mechanism may be provided of a simple configuration which is capable of switching the transport direction of a transported information recording medium. One end may be a biasing member for biasing a pinch roller toward a transport roller engages a support shaft which supports the pinch roller, whereas the other end of the biasing member engages a retaining member which retains the support shaft. In the medium transport direction switching mechanism, rotational behavior of the pinch roller centering upon a rotational center of the transport roller is possible between a first facing position and a second facing position, wherein the pinch roller moves to the first facing position when the transport roller rotates positively, and moves to the second facing position when the transport roller rotates negatively.

Abstract: An equalizing roll and web tracking apparatus to be used in manufacturing for providing equal tension across a web during winding operations such as used in polymer film applications, corrugators, paper machines, printing presses, cloth winders, and metal winding operations. The equalizing roll utilizes a common axis shaft mounted horizontally on two bearings or clamped rigid supports allowing for rotation. Mounted in the center of the axis shaft is a bearing assembly having convex and concave portions disposed within a sleeve. The bearing assembly is centrally mounted inside a hollow cylinder or roll machined to be in balance with respect to the centrally disposed bearing assembly. The mating of the concave and convex portions of the bearing permits a selected degree of lateral rotation in a range of from about 1 degree to about 10 degrees. As the web runs over the roll, any imbalance of lateral tension will cause the roll to pivot at it's center permitting the roll to move upward on the side of least tension until the web tension is equalized across the entire roll. The equalizing roll tracking apparatus utilizes an adjustable control arm assembly having a pair of adjustable pivot arms with steering arms linked to sensor arms. The distal ends of the sensor arms are in contact with the outer edges of a web, sheet, or belt of material supported by at least one idler roll and utilizing at least one equalizing roll. The steering arms float on the outer diameter of the equalizing roll. The sensor arms are pivotally linked to the steering arms so that the misalignment of the belt, sheet or web moves the sensor arms slightly causing the steering arms to pivot and exert pressure on the equalizing roll thereby counteracting and aligning the direction of the web, belt, or sheet of material supported thereby.

Abstract: A sheet conveying device includes a sheet detection unit and a position adjusting mechanism. The position adjusting mechanism is disposed on a downstream side of the sheet detection unit in a sheet conveying direction in the sheet conveying path, includes an adjusting roller pair, and performs skew correction and positional displacement correction of a sheet, while conveying the sheet. The sheet conveying path includes a first conveying roller pair disposed on an upstream side of the position adjusting mechanism in the sheet conveying direction, and a curved part disposed between the adjusting roller pair and the first conveying roller pair, which curves in an S shape so as to be convex in a front and back side direction of the sheet alternately at different positions in the sheet conveying direction. The adjusting roller pair nips and conveys the sheet together with the first conveying roller pair.
