A flexible lance drive device is disclosed that has, in a compact housing, a drive motor between an inner and an outer wall, a linear array of pairs of driven upper and lower drive rollers outside the outer wall coupled to the drive motor via shafts extending through both of the inner and outer walls. Each driven roller is fastened to its shaft via a quick release device. A drive sprocket is fastened to each shaft outside the inner wall. The drive motor is coupled to each of the drive sprockets via a serpentine belt carried outside the inner wall. The lower driven rollers are rotatably carried by the inner and outer walls. The upper driven rollers are rotatably carried by a block positioned between the inner and outer walls and coupled to the lower driven rollers by a pair of parallel links releasably biased by a piston driven linkage.

An information terminal device includes a roll paper printer that pulls out paper from paper roll, performs printing, and cuts the paper, a paper guide that guides the paper, and an issue port through which the paper is discharged, wherein the paper guide includes a first guide for guiding a first surface of the paper, a roller for guiding a second surface of the paper being a surface opposite to the first surface at a position facing the first guide, and a support portion permitted to movably support a shaft of the roller.

A medium conveying apparatus includes a conveyance roller to convey a medium, a facing roller facing the conveyance roller and swingable by a thickness of the medium conveyed, and a guide to guide the medium conveyed by the conveyance roller and the facing roller. The guide moves in conjunction with a swing of the facing roller.

A coreless log of convolutely wound web material is formed by directing the web around an applicator roller that is in contact with a first surface of the web. An additive is transferred from a supply roller to the applicator roller over a first distance of the web and stopped over a second distance of the web. The web is directed around at least one further roller that is in contact with the second surface of the web that is opposite the first surface. The web is then wound around an elongated mandrel. The first distance of the web comprises a first set of windings nearest the center of the log, and the second distance of the web comprises a second set of windings wound around and extending radially outward from the first set of windings. The mandrel may then be removed to form the coreless log.
