A sheet conveying device includes a discharging roller pair, a discharge sheet holding portion, and a stopper member. The discharging roller pair discharges the sheet member outside from a sheet discharge port by rotating in a forward rotational direction. The discharging roller pair includes a first conveying roller, and a roller member. The discharge sheet holding portion is for holding the sheet member discharged outside by the discharging roller pair. The stopper member is swingably supported on a rotational shaft of the first conveying roller. The stopper member allows the sheet member to be discharged to the discharge sheet holding portion when the discharging roller pair rotates in the forward rotational direction, and prevents the sheet member from intruding into the nip portion from the discharge sheet holding portion when the discharging roller pair rotates in the reverse rotational direction.

Provided is a printing apparatus including a printing head, transport rollers (sheet transport rollers) configured to sandwich and transport a medium (label sheet), a medium bending unit (bending member) configured to bend the label sheet to peel off a label from a backing sheet when the label sheet has a configuration in which the label is attached to the backing sheet, and a medium guide (sheet guide) configured to contact with one edge in a width direction of the label sheet to be bent by the bending member. The sheet transport rollers include a biasing mechanism configured to bias the label sheet in a direction intersecting a transport direction of the label sheet and also toward the sheet guide, during transport of the label sheet.

An image recording apparatus for recording an image on a sheet includes a recording section which records the image on the sheet in a transport passage for transporting the sheet in a transport direction and multiple plates which are spaced apart from each other in a widthwise direction. These multiple plates include a first type of plate and a second type of plate. Plates of a first type of plate are configured to overlap a sheet when viewed in a direction perpendicular to the transport direction and the widthwise direction, while plates of the second type of plate do not.

A printing apparatus includes a feeding unit, a pair of rollers, a printing unit, and a control unit. The control unit can execute skew correction. The control unit can execute control to convey a preceding printing medium and a succeeding printing medium by the pair of rollers in a state in which a trailing edge portion of the preceding printing medium and a leading edge portion of the succeeding printing medium overlap. The control unit sets an execution timing of the skew correction for the succeeding printing medium based on positions of the preceding printing medium and the succeeding printing medium if a predetermined condition is met. The predetermined condition is that the preceding printing medium reaches a position at which a remaining print range for the preceding printing medium equals a predetermined print range.

A clamp includes first and second rising portions that rise from a base portion, a first extending portion extending along a first top surface of a table from the first rising portion, a second extending portion extending along a second top surface of the table from the second rising portion, a first clamp portion to urge a medium toward the first top surface, and a second clamp portion to urge the medium toward the second top surface. A gap located above a groove in the table is provided between the first clamp portion and the second clamp portion.

A printer uses at least two centrally positioned single nip de-skew, lateral registration, and process direction registration devices to remove skew, laterally register, and register in the process direction substrates moving along a media transport path. The single nip de-skew, lateral registration, and process direction registration devices include a fixed roller having a low coefficient of friction and a length longer than a rotating wheel that forms a nip with the fixed roller having a high coefficient of friction to enable an actuator to move the rotating wheel along the fixed roller to laterally register and de-skew substrates.

A printing device includes: a substrate feed-out section; a substrate transport section; a storage which stores the width size of the substrate; a skew correction section including a skew sensor which detects the skew of the substrate, and adapted to correct the skew of the substrate with reference to an output of the skew sensor and the substrate width size stored in the storage; an image recording section which performs an image recording operation on the substrate; a first sensor which detects a width size-changed portion of the substrate upstream of the skew correction section with respect to the transport direction; and a controller. Upon the detection of the width size-changed portion, the controller stops the substrate skew correction while continuously transporting the substrate. After the width size-changed portion of the substrate reaches a reference position downstream of the skew correction section, the controller restarts the skew correction.

A machine for printing substrates and a method for printing substrates using the machine, which has a print head, the print head having at least one ejection nozzle for ejecting a product on the substrate; translation device with a movable part, the translation device configured for supporting and translating the substrate by the movable part; positioning device for establishing and fixing a relative position between the substrate and the print head. The machine additionally has guiding device for guiding the movable part; and holding device for fixing the substrate with respect to the movable part; with the substrate being fixed to the movable part and the movable part guided by the guiding device, the substrate can be translated to receive the product being ejected.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor to detect a position of a print media, a platform comprising a plurality of cellular omni wheels, and a processor communicatively coupled to the at least one sensor and the plurality of cellular omni wheels, wherein the processor calculates a desired movement of each one of the plurality of cellular omni wheels based on the position of the print media.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor, omni wheels, a motor coupled to each omni wheel, and a processor communicatively coupled to the at least one sensor, and the motors, wherein the processor calculates a desired movement to move the omni wheels based on the position of the print media.
