Abstract:
The present disclosure refers to media feeding for a printing system comprising: a first operation mode in which, to feed a print medium, a pre-pick roller assembly moves to an engaged state to advance the print medium in an advance direction to a pick roller and wherein, upon surpassing the pick roller by a first coupling distance, the pre-pick roller moves to a disengage state detached from the print medium; and a second mode of operation in which, to feed a print medium, the pre-pick roller assembly moves to an engaged state to advance the print medium in an advance direction to the pick roller and wherein, upon surpassing the pick roller by a second coupling distance, the pre-pick roller moves to a disengage state detached from the print medium being the second distance higher than the first distance.
Abstract:
A document feed device includes a tray in which a document is loaded, a pickup roller to be moved upward or downward to a standby position spaced apart from the document or to a pickup position to pick up the document in the tray, a separator to separate each sheet of the picked-up document, an inclined guide to connect an end of an exit of the tray to an entrance of the separator and to guide a bottom surface of the picked-up document, and a document guide member movable to a first position protruding from the inclined guide to guide the picked-up document or to a second position below the inclined guide.
Abstract:
An example bridge module includes a media transport roller to move in a translational direction, a rotatable guide proximate to the media transport roller, a handle coupled to the rotatable guide to cause the rotatable guide to articulate into an open configuration and away from the media transport roller, and an elongated member operatively connected to the rotatable guide, the elongated member to articulate into the open configuration creating an unobstructed pathway to the media transport roller.
Abstract:
There is described a thermal printer apparatus including one or more thermal print heads (12, 14) fixedly mounted with respect to a print media path (18), one or more platen roller assemblies (32, 34) each including a platen roller (32a, 34a) adapted to press print media in the print media path (18) against at least one print head and a frame (32b, 34b) adapted to support a respective platen roller and a pivotally mounted support member (36) adapted for mounting the platen roller assembly frames to extend from the support member (36) and press its respective platen roller against the print head.
Abstract:
A roller device capable of eliminating a wasteful space by providing a motor and a speed reducer inside or coaxially with a cylindrical roller and capable of manually feeding paper and electronics including a printer using the roller device, the roller device comprising a motor (5), a sun gear (7), and planetary gears (8) disposed in the cylindrical roller (2), a first internal gear (10) provided in the inner surface of the cylindrical roller (2), and a second internal gear (11) provided in the inner surface of a bearing body (12), the bearing body (12) being formed so that the rotation thereof is suppressed by a specified force, whereby the rotating speed of the motor (5) is reduced to rotate the cylindrical roller, and the bearing body is rotated with a force larger than a specified one so as to manually rotate the cylindrical roller.
Abstract:
A printer comprising a printer main body (11), a cover (50), a sprocket (12) for delivering a sheet from a sheet roll (16), a platen roller (13) used in printing on the sheet, a thermal head (51) for printing on the sheet, a drive mechanism for rotating the sprocket (12) and platen roller (13), and a gear mechanism for rotating, by the drive mechanism, the ribbon core of an ink ribbon cassette (60) mounted on the cover (50), the printer main body (11) being provided with the sprocket (12) and platen roller (13), the cover (50) being provided with the thermal head (51), wherein the platen roller (13) is disposed downstream of the sprocket (12) and it is arranged that when the cover (50) is closed, the core gear (65) of the ink ribbon cassette (60) meshes with a gear (34) to eliminate the backlash of the platen gear (15).
Abstract:
The invention relates to a printer (10) for printing on single sheets (126, 128) and on at least one endless paper strip (122) on a printing support area (19). In said printer a single sheet (126, 128) is fed by manual displacement on a paper feed platform (20) from the operator side towards the printing station (36, 56), where it is able to cover the endless paper strip (122) at least along part of its width. The endless paper strip (122) is fed from the operator side to the printing station (36, 56). In addition, one driven intake roller (98; 38) each of a pair of intake rollers (100; 44) is assigned to the supply channel (34) for the endless paper strip and to the supply channel for the single sheets (30). A backing roll (42) mounted on an oscillating element (48) can be pressed against the driven intake roller (98; 38) of either the endless paper supply channel (34) or the single sheet supply channel (30).
