A drying unit has: a first space; a first nozzle provided in the first space; a first air blowing unit that supplies air inside of the first space to the first nozzle; a second space provided adjacent to the first space on a downstream side in a conveyance direction of the first space and communicates with the first space; a second nozzle provided in the second space; a heater that heats air inside of the second space; a second air blowing unit that supplies the heated air to the second nozzle; a third space provided adjacent to the second space; and a third air blowing unit that sucks air inside of the third space and exhausts the air to outside of the drying unit. A direction in which air is blown out from the first nozzle has a component directed toward the second space in the conveyance direction.

A printing device includes a printing apparatus that includes a transport unit including a roller pair that nips and transports a medium, a printing unit that prints on the medium and a first sensor that detects the medium or a mark at a position downstream of the roller pair. The printing device also includes a first motor capable of driving the roller pair to a non-nipping state and to a nipping state, and a controller that controls the transport unit and the first motor so as to perform an assistance operation to assist setting of the medium. The assistance operation performed by the controller. When the first sensor detects the medium or the mark, the controller causes the medium to be nipped by the roller pair, and a skew correction operation in which the medium is transported and reverse transported is performed.

A sheet conveying apparatus includes: a supply unit for supplying a sheet; a first switching unit disposed on a conveyance path of the sheet and configured to switch between a state of nipping the sheet supplied by the supply unit and a state of releasing the nipping of the sheet; a first tension applying unit disposed on one side of the first switching unit in a conveyance direction of the conveyance path and configured to apply tension to the sheet; and a detection unit disposed on the other side of the first switching unit in the conveyance direction of the conveyance path and configured to detect the tension of the sheet, wherein, in a state where the nipping of the sheet is released by the first switching unit, the first tension applying unit adjusts the tension of the sheet while the detection unit detects the tension of the sheet.

The invention relates to a plant and a process for pre-coating and subsequent digital sol-gel inkjet printing on metallic strips, wherein on the dried ink a protective clear coat will then be applied. The core of the invention lies in the fact that printing is of the sol-gel ink type and pre-coating is no longer carried out by the separate application of two coats, a primer and a base coat, with relative drying and cooling phases of the coats, but by the application of a single coat that combines the functions of primer and base coat. In addition, printing with a special sol-gel type ink that does not require UV treatment, but only a simple drying of the ink after application, simplifies the process even further.

According to an embodiment, a printer includes a damper that moves towards a continuous sheet by a predetermined distance and applies a tensile force to the continuous sheet on a conveying path on which the continuous sheet is conveyed by the feed roller. The printer further includes a limiter that switches a state of the damper between an unlimited state in which a movement distance for the damper is not limited and a limited state in which the movement distance for the damper is limited so that no tensile force is applied to the continuous sheet.

According to an embodiment, a printer includes a damper that applies tension to continuous paper by moving a predetermined distance toward the continuous paper in a conveying path of the continuous paper to be conveyed. The printer further includes a limiter that switches a state of the damper between a non-limited state in which a moving distance of the damper is not limited and a limited state in which the moving distance of the damper is limited to reduce tension to be applied to the continuous paper.

A thermal printer according to this embodiment forms a stereoscopic image by applying heat to a printing medium having a surface evenly coated with foaming capsules which foam when heated. More specifically, the thermal printer includes a conveyance guide which is formed into a convex shape whose apex is an image formation position where heat is applied to the printing medium, and regulates the position of the conveyed printing medium, and a thermal head assembly which is installed such that a thermal head distal end portion contacts with the printing medium conveyed by the conveyance roller from below the image formation position, and forms a stereoscopic image by applying heat to the printing medium.

A printer is provided with: a feed roller on which an elongated shaped medium is wound in a roll form and from which the medium is unwound and fed in a predetermined transport direction; a printing unit that prints an object to be printed on the medium fed from the feed roller; a take-up roller that takes up the medium printed by the printing unit in a roll form; and a tension applying member that applies a tension to the medium by making a contact with a surface opposite to a print surface of the medium. The tension applying member has a support portion disposed at a center position in a width direction of the medium, and an oscillation shaft extending in the width direction of the medium and adapted to oscillate in contact with the medium. The oscillation shaft is oscillated on the support portion serving as fulcrum.

A recording device includes a conveyance mechanism, a recording mechanism, a rotational mechanism of a plurality of take-up spindles, and a control unit. The conveyance mechanism is configured to convey a recording medium intermittently in a conveyance direction. The recording mechanism is configured to record by reciprocatingly scanning a recording head in a direction that intersects with the conveyance direction. The rotational mechanism is configured to take up the recording medium. The control unit is configured to control the conveyance mechanism and the rotational mechanism to substantially synchronize conveying of the recording medium by the conveyance mechanism and taking-up of the recording medium by the rotational mechanism.

A web handling system is disclosed. The web handling system includes a roller wheel including two or more rollers configured to engage a print medium, a motor to rotate the roller wheel and a controller to transmit a signal to the motor indicating which of the two or more rollers are to engage the print medium.
