The paper cutting device includes: a lower frame configured such that a platen roller and a thermal head are disposed on the top surface thereof and provide a paper movement path and a drive unit is contained therein; an upper frame configured to form the paper movement path in association with the lower frame, and to open the paper movement path; a fixed cutter configured to be disposed on the upper frame, and to cut the roll paper; a movable cutter configured to be disposed on the lower frame, to cut the roll paper, and to allow the roll paper to move; and a jam control unit configured to detect a jam of the roll paper, and to detect the opening of the paper movement path and lower the movable cutter.

A printer includes: a body with a set of interior walls defining a media enclosure configured to receive a media cartridge, and a latch recess in one of the interior walls, including a retaining surface, and a ramp surface; a lid rotatably coupled to the body and movable between open and closed positions; and a latch movably supported by the lid between a locked position and an unlocked position, the latch including: a bias member biasing the latch towards the locked position, a hook surface configured to engage the retaining surface when the lid is closed and the latch is in the locked position, and a cam surface configured via the bias member, when the lid is closed and the latch is released to the unlocked position, to slide against the ramp surface and lift the lid to an intermediate position between the open and closed positions.

A roll paper printer includes: a case configured to accommodate a paper roll in which paper is wound in such a way that one surface of the paper faces outward; a transport roller that pulls the paper from the paper roll and transports the paper in a transport direction; a first paper guide configured to come into contact with the other surface of the paper upstream of the transport roller in the transport direction; a second paper guide that faces the first paper guide and is configured to come into contact with the one surface of the paper; a third paper guide configured to be attached/detached and configured to come into contact with the one surface of the paper and curve the paper upstream of the second paper guide in the transport direction; a sensor configured to detect the third paper guide; and a controller that decreases, when the third paper guide is detected by the sensor, a transport speed for the paper transported by the transport roller to be lower than that when the third paper guide is not detected.

A printer device includes: a recessed accommodation part accommodating a roll-shaped continuous paper; a pair of rack gears arranged in a staircase-like shape on a paper conveyance direction side of the continuous paper, and having tooth rows arranged in a first direction orthogonal to the paper conveyance direction so as to face each other; a pinion gear arranged between the pair of rack gears and fitting into the tooth rows of the pair of rack gears, and a pair of paper guides respectively provided at one end portion of an upper rack gear in the first direction and anther end portion of a lower rack gear in the first direction, and supporting side surfaces of the continuous paper accommodated in the accommodation part. The pair of paper guides perform an opening or closing movement in the first direction by the pair of rack gears and the pinion gear.

A method of operating a device to receive a print medium is disclosed. Rotation of a receiving device to receive a print medium is detected, whereby the rotation is caused by an external force. An assisting force is applied to further rotate the receiving device in response to the detected rotation.

A printer includes a print head that prints on recording sheet, a platen roller that transports the recording sheet pinched between the print head and the platen roller, a movable blade that cuts the recording sheet, a roller driving module that drives the platen roller, and a cutter driving module that drives the movable blade. The roller driving module and the cutter driving module are both provided at one end along an axial direction of the platen roller.

A liquid discharging apparatus is provided capable of preventing liquid from being discharged onto a medium to which any foreign substances adhere. A printing apparatus (10) (liquid discharging apparatus) includes a holding member (21) configured to hold a roll body (R1) on which a medium (M) is wound, a transport unit (40) configured to transport the medium (M) fed from the roll body (R1) held by the holding member (21) along a transport path (FP), a discharging unit (61) configured to discharge liquid onto the medium (M) transported by the transport unit (40), and a vibration unit (34) configured to apply vibration to the medium (M) being transported from the holding member (21) to the transport unit (40). In the transport path (FP), a path on which the medium M to be subjected to vibration by the vibration unit (34) is transported is referred to as a vibration transport path (FP1), and the vibration transport path (FP1) is configured to extend vertically upward as approaching from the holding member (21) to the transport unit (40).

A thermal-transfer printing apparatus includes a roll-paper-supplying unit that rotates an image-receiving paper roll and unwinds and winds a roll type of first image-receiving paper, and a print unit that includes a thermal head for heating a thermal transfer sheet and that forms an image by transferring a color material from the thermal transfer sheet to the first image-receiving paper. With the image-receiving paper roll removed, a reverse unit that reverses a sheet type of second image-receiving paper is mountable in a region in which the image-receiving paper roll used to be contained. The print unit forms the image on the first image-receiving paper in a first printing mode in which the image-receiving paper roll is contained in the region, and the print unit forms an image on both surfaces of the second image-receiving paper in a second printing mode in which the reverse unit is mounted on the region.

A roll support structure is used in a printer which pulls out a sheet material from a roll on which the strip-shaped sheet material is wound and performs printing on the sheet material, where a holding portion which is inserted inside a tubular core of the roll to hold the roll rotatably includes a first portion which is in contact with an upper portion of an inner surface of the core and supports the roll from below and a second portion which is located further on a downstream side in a conveyance direction of the sheet material than a contact point between the first portion and the core and prevents movement of the oscillating roll supported by the first portion to the upstream side in a conveyance direction within a predetermined range.
