There is provided a printing apparatus. A first roller nips and conveys, in a conveyance direction, a printing medium. A second roller nips and conveys a printing medium at a downstream side of the first roller in the conveyance direction. A print unit prints an image on a printing medium conveyed by the second roller. A control unit, until printing by the print unit reaches a vicinity of a trailing end of a print length, sets a nip pressure of the first roller to a first pressure, and when printing by the print unit reaches the vicinity of the trailing end of the print length, sets the nip pressure of the first roller to a second pressure that is greater than the first pressure.

A system and method for stabilizing a substrate during printing of images and subsequent cutting of the printing images with the system. The system comprises a printer assembly and a cutting assembly for printing images on a print media and then cutting the images from the print media. The printer assembly and cutting assembly are positioned in the system such that the media is printed and cut before advancing further through the system. The system has a web feeding system having a plurality of pairs of levers for providing different amounts of pinch force to the web during the printing and cutting processes so as to retain the media in a substantially flat and stationary position for printing as well as cutting.

A printer includes a driving roller to move a medium supported on a support table in a predetermined transportation direction, and pinch roller assemblies each including a pinch roller, a support to support the pinch roller to allow the pinch roller to contact, or to be spaced from, the driving roller, and an actuator provided upstream in the transportation direction with respect to the pinch roller. The actuator includes a contact portion contactable with the support, and an operation portion to press the contact portion to the support to move the pinch roller in a direction away from the driving roller.

An image forming apparatus includes a printing device, a nipping rotator, an upstream support stand, a plurality of rotators, a supporter, and an adjusting mechanism. The printing device prints an image on a plate-shaped printing medium. The nipping rotator conveys the plate-shaped printing medium. The upstream support stand supports the plate-shaped printing medium at a position upstream from the nipping rotator in a conveyance direction of the plate-shaped printing medium. The plurality of rotators are disposed side by side. The supporter supports the plurality of rotators. The adjusting mechanism adjusts relative positions of the plurality of rotators and the supporter.

An image recording apparatus includes: a casing having an internal space; a conveying passage formed inside the casing; a first roller pair positioned in the conveying passage, having a driving roller and a driven roller, and configured to pinch a sheet and to convey the sheet in a conveying orientation; a platen positioned on a downstream side in the conveying orientation of the first roller pair, and having a supporting surface supporting the sheet; a recording part positioned above the platen and configured to record an image on the sheet supported by the platen; a second roller pair which is located on the downstream side in the conveying orientation of the supporting surface of the platen, and which is configured to pinch the sheet and to convey the sheet; and a moving mechanism configured to move the platen to a printing position and to a release position.

The present invention relates to a movable thermal printing device, which comprises a gear set, a pressing roller set, and a heating component. The gear set includes a first motor, a first gear, and a rack gear. The pressing roller set includes a frame, a first roller, and a second motor. A sensing medium is attached below the first roller. When the first gear rotates counterclockwise, the rack gear, the pressing roller set, and the sensing medium will be driven to move upwards and away from the heating component. When the first gear rotates clockwise, the rack gear, the pressing roller set, and the sensing medium will be driven to move downwards and contact the heating component for printing sensing medium and for avoiding the sensing medium from contacting the heating component in reverse rotation and thus avoiding the problems of damages or print failure.

A first conveyance path and a second conveyance path are formed in a housing. The first conveyance path extends in a conveyance direction to reach a first discharge port for discharging a sheet. The second conveyance path extends in the conveyance direction at a position higher than the first conveyance path to reach a second discharge port for discharging a sheet. The second discharge port is located at a position upstream of the first discharge port in the conveyance direction. A first print engine is provided at the first conveyance path. The first print engine is configured to print an image by using a recording agent on a sheet conveyed along the first conveyance path. A second print engine is provided at the second conveyance path. The second print engine is configured to print an image by using a recording agent on a sheet conveyed along the second conveyance path.

A transport roller pair includes a drive roller and a follower roller set. The drive roller is driven to rotate about a shaft. The follower roller set transports a medium held between the drive roller and the follower roller set, by being made to rotate about a shaft by the drive roller. The follower roller set includes at least one first roller and at least one second roller. The at least one first roller forms a first nip region by contacting the drive roller. The at least one second roller forms a second nip region by contacting the drive roller, at a position downstream of the first roller in a transport direction of the medium. The first roller is smaller in inertia than the second roller.

A vacuum coating device for a flexible substrate is provided, including a vacuum coating chamber and a transition chamber which are connected to each other. The vacuum coating chamber and the transition chamber communicate with each other through a slit. The vacuum coating device further includes a cooling roller, which is fixed in the transition chamber through a tension adjusting component. The cooling roller includes a roller body and a shaft, the roller body is fixedly installed on the shaft, and the roller body and the shaft are coaxial. Multiple heat dissipation passages are provided in the roller body along an axial direction of the roller body. Good cooling function is achieved and the flexible substrate is prevented from generating winkles.
