A printing unit in a sheet-fed printing machine includes a printing cylinder, an upstream transfer cylinder and a downstream transfer cylinder. The transfer cylinders each include a device for decelerating/accelerating a sheet. The device, in particular, includes at least one gripper bar being movable in a substantially radial direction to change the tangential speed of the gripper bar and thus of the sheet. A printing unit of this construction allows the sheets to be transported at a lower speed and at a shorter distance from one another during the printing process, resulting in a better print quality and a higher throughput of the machine. A sheet-fed printing machine including such a printing unit is also provided.

The ridge part T projecting from an interior surface of an opening and closing cover 3 of a printer 1 is provided at part of a head 3b that make contact with a mountless label continuous body P including an adhesive agent layer on one surface thereof. The head 3b is located at a free end of the opening and closing cover 3. A third ridge part T3 is provided on a third surface S3, which is located in vicinity of an intersecting line between a first surface S1 and a second surface S2. The third ridge T3 has a longer projecting length than a ridge part T1 projecting from the first surface S1, and has a longer projecting length than a ridge part T2 projecting from the second surface S2.

According to one embodiment, there is provided a printer device which prints on an adhesive member including an adhesive material on one surface and includes a thermal head, a platen, a fixed blade, a movable blade, an operation unit, and a control unit. The thermal head prints on the adhesive member by generating heat. The platen is arranged to face the thermal head. The fixed blade is arranged at a position where a blade edge faces a conveyance path of the adhesive member conveyed between the thermal head and the platen. The movable blade is arranged at a position where a blade edge of the movable blade faces the blade edge of the fixed blade via the conveyance path and moved at a first speed to a position where the blade edge of the movable blade is brought into contact with the blade edge of the fixed blade. The operation unit receives a first operation for instructing to start cleaning the movable blade from an operator. The control unit moves the movable blade to a position where the blade edge of the movable blade is exposed above the conveyance path at a second speed slower than the first speed when the operation unit receives the first operation.

A recording apparatus includes a printing portion, a first conveying portion, and a second conveying portion. The printing portion ejects liquid to print a medium having elasticity. The first conveying portion is disposed upstream of the printing portion in a conveying direction along which the medium is conveyed to the printing portion, and conveys the medium while stretching the medium in the conveying direction and in a width direction orthogonal to the conveying direction. The second conveying portion conveys the medium conveyed by the first conveying portion while keeping the medium facing the printing portion.

A recording apparatus includes a printing portion and a first conveying portion. The printing portion ejects liquid to print a medium having elasticity. The first conveying portion is disposed upstream of the printing portion in a conveying direction along which the medium is conveyed to the printing portion. The first conveying portion includes at least two conveying bodies disposed in the conveying direction and around which the medium is alternately wound. The conveying bodies each include a shaft extending in a width direction orthogonal to the conveying direction and a plurality of rollers rotatably supported by the shaft. The plurality of rollers are supported to be inclined outward with respect to the conveying direction from upstream to downstream in the conveying direction.
