摘要： A paper feeder for transporting paper sheets, includes: a head fan that blows air on the paper sheets; a suction fan that applies negative pressure to the paper sheets blown by the head fan; a switching member that changes the direction of the air from the head fan; a head shutter that blocks the flow of the air directed by the switching member; and a hardware processor that determines the blocking time of the airflow, wherein the switching member changes the air direction between a first direction for floating the paper sheets and a second direction toward the suction fan, and the hardware processor determines stop timing of the air blow in the second direction directed by the switching member as the start timing of clocking the blocking time of the airflow, based on the weight and the resistance to an external force of the paper sheets.

摘要： Alignment apparatuses include a frame and contact elements connected to the frame. The contact elements contact items that are to be transported in a processing direction relative to the frame. The contact elements are in permeant fixed positions relative to the frame, and do not move relative to the frame. Adjustable mounts are connected to the frame and move the frame in the processing direction and in a perpendicular cross-processing direction. A controller is electrically connected to the adjustable mounts, and the controller is adapted to control the adjustable mounts to simultaneously move the frame and all the contact elements in the cross-processing direction and the processing direction while rotating the frame. Methods laterally shift imaging on sheets that have had rotational correction performed by such alignment apparatuses.

摘要： A digital printing device, comprising a suction transport means (1). The suction transport means (1) comprises a transport belt (11) used for transporting a sheet material. At least one first suction box (14), which is used for sucking the sheet material on the transport belt (11) by means of negative pressure during transport, is provided in the space defined by the transport belt (11). Multiple first suction holes in communication with the first suction box (14) are provided on the transport belt (11). At least one side of the first suction box (14) is provided with a movable door (15) which moves in a direction perpendicular to the transport direction to make the first suction box (14) fit the sheet material to maintain a negative pressure state. Using the transport belt (11) during printing, the digital printing device avoids the problem of poor registration accuracy, and improves the printing effect.

摘要： A roller which has woven fabric at a surface thereof and which is employed in an apparatus permitting achievement of conservation of resources, conservation of energy. Roller 1 provided with covering 3 includes woven fabric at its surface is idler means or drive means for conveying, supply, of an object, means for air cooling or drying a moving object, rotating means making use of suction of an object, or is for cleaning a contact surface to which roller 1 is opposed, and has at the surface woven fabric 2 with variation or combination of weave pattern(s). The woven fabric 2 includes weaving in a linear pattern of bands or different patterns. It also has open holes including lattice-like gaps 8 or a rectangular pattern 6 for control of air permeability formed from weft yarn 25 and warp yarn 26.
