A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.

A recording apparatus includes a conveyance unit, a conveyance path, a double-sided conveyance path, and first and second charge eliminators. The conveyance unit conveys a recording medium having first and second surfaces in a first direction through the conveyance path to a recording area where recording is performed by a recording unit on the first surface. The recording medium then passes through the double-sided conveyance path before recording is performed on the second surface. The first charge eliminator eliminates charges from the first surface and is disposed at a position downstream of a junction between the conveyance path and the double-sided conveyance path in the first direction and upstream of the recording area in the first direction. The second charge eliminator eliminate charges from the second surface and is disposed downstream of the junction in the first direction and upstream of the recording area in the first direction.

A device and method for treating several surfaces of objects, including treatment equipment for carrying out a treatment on a surface of an object; a shuttle having at least two locations configured to receive objects, which is mounted to as to be able to move between two positions, passing through intermediate positions in which the shuttle presents one surface of the objects to the treatment equipment; a first piece of handling equipment capable of placing an object in a first location when the shuttle is in its first position; a second piece of handling equipment configured to remove one object from the second location; and third piece of handling equipment configured to remove the object from the first location and turning it before placing the object in the second location.

Disclosed herein is a substrate cooling unit for use with a duplex aqueous ink jet image forming device. The substrate cooling unit includes a first transport belt that is in contact with a portion of an outer surface of the first cooling roll to substantially sandwich individual sheets of image receiving media between a first cooling roll and the first transport belt. The substrate cooling unit includes a second cooling roll positioned downstream of the first cooling roll in a process direction and a second transport belt that is in contact with a portion of an outer surface of the second cooling roll to substantially sandwich the individual sheets of image receiving media between the second cooling roll and the second transport belt. The second transport belt includes a bottom layer of woven or non-woven fibers and a top rubber layer.

In example implementations, a printer module is provided. The printer module includes a co-axial split drive roller, a first motor, a second motor, and a print bar. The co-axial split drive roller includes a first roller and a second roller that are movably coupled at a center of the co-axial split drive roller. The first motor is coupled to the first roller. The second motor is coupled to the second roller. The print bar is coupled to the housing over the co-axial split drive roller.

According to one embodiment, a paper conveyance device includes a conveyance unit configured to convey long cut paper in a longitudinal direction, a measuring unit configured to measure a length of the cut paper in the longitudinal direction, which is conveyed by the conveyance unit, a reversal mechanism that reverses a front surface and a back surface to each other with conveying the cut paper, and a reversal unit configured to convey the cut paper in the reversal mechanism. The reversal unit conveys the cut paper at a first speed when the measuring unit measures that the length of the cut paper is less than a predetermined length, and conveys the cut paper at a second speed slower than the first speed when the measuring unit measures that the length of the cut paper is equal to or more than the predetermined length.
