An imaging system includes a steering roller and a positioning mechanism. The steering roller extends along a longitudinal direction, and being tiltable about a fulcrum to adjust an alignment position of an endless belt. The positioning mechanism is coupled to the steering roller, to position an adjustable position of the fulcrum of the steering roller, along the longitudinal direction of the steering roller. The positioning mechanism includes a guide that extends along the longitudinal direction of the steering roller, and a protrusion that engages with the guide, and that is located at the adjustable position of the fulcrum.

A conveyor belt monitoring system may utilize one or more ultrasonic sensors to identify variations in the position of the conveyor belt. These variations may be minor variations in belt position, which can be identified by the belt monitoring system well before they would be readily perceptible by a user. The monitoring system may be operated in conjunction with one or more belt adjustment mechanisms which can be used to correct the path of the conveyor belt based on information gathered by the monitoring system.

There is provided a medium conveying device which includes a conveyance belt passed around a first roller and a second roller and configured to support and convey a medium on a supporting surface, and in which a controlling unit is able to execute first control to determine whether a first skewing direction and a second skewing direction are the same, the first skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the first rotational direction, the conveyance belt moves toward one side or the other side in a width direction intersecting a moving direction of the conveyance belt, and the second skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the second rotational direction, the conveyance belt moves toward the one side or the other side in the width direction.

A roller for a conveyor is described. The roller can have a first end, a second end, and a crown defined along a length of the roller between the first end and the second end. The crown of the roller includes a groove defined along an apex portion of the crown. The groove can support an O-ring and the crown can support a flat band mounted over the O-ring in the groove.

The present invention refers to a conveyor belt comprising a drive roller with a constant section cylinder and conical tip teeth, a mesh type drive belt, wherein said holes coincide with the teeth of the drive roller and a sliding plate, the drive belt being supported on the sliding plate. Wherein coupling between the drive belt and the teeth allows reducing longitudinal and transversal strain of the mesh type drive belt.
