Abstract: To provide a recording apparatus for recording on a sheet by a recording head, including: a carriage for carrying the recording head and moving in a direction crossing a sheet transporting direction; a guide shaft for guiding a movement of the carriage; and a guide shaft lifting mechanism for changing a position in height of the guide shaft at three or more stages without changing a position of the guide shaft in the sheet transporting direction.

Abstract: A printing machine for booklet-like medium (2) is disclosed as having a booklet resting surface (4) to which a sheet insertion passage (5) is opened, a booklet pressing unit (10) which presses booklet-like medium, which is centrally unfolded on the booklet resting surface at a bound portion (2b) and whose sheet (2a1) of a page to be printed and inserted through the sheet insertion passage, against the booklet resting surface, a print page positioning unit (40) composed of a pair of sheet hazing rollers (42a, 42b) for positioning the sheet (2a1), of the page to be printed, at a given print position, and a print head section (18) having a pair of right and left print heads (19a, 19b) mounted at both sides of the sheet (2a1) of the page to be printed, respectively.

Abstract: In a page-turning device for a printer, arms are provided at the ends of a support shaft, and a pair of rollers are fitted around a roller shaft that is located between the distal ends of arms. Springs are attached to the base ends of the arms to press the rollers against a medium to be printed. Depending on the width of the medium, the positions of adjustment brackets can be changed, such that the urging forces produced by the springs are adjusted, so as to control the pressing forces exerted by rollers, thereby assuring substantially uniform force application onto at least two locations of the page such that the page can be readily turned without inappropriate folding, bending or creasing.

Abstract: A method of providing at least one indicia on the edges of a plurality of stacked leaves assembled one on top of the other to form a book or pamphlet, each respective leaf having marks thereon on at least one face of the leaf adjacent said edge, the assemblage of the marks on the individual leaves forming said indicia on the edge. The indicia or indicia are broken down into elements and each element is assigned Cartesian coordinates according to the X and Y coordinate system with the y-coordinates corresponding to the pagination of a respective leaf, and the x-coordinates for each respective leaf corresponding to individual mark elements on the face of the leaf.

Abstract: A printer prints upon a book having a plurality of pages bound at a binding edge (1). The book is opened, placed on a supporting surface (16) and fed in a feed direction parallel to the binding edge. A supporting shaft (13) extends parallel to the supporting surface. A channel (17) receives the binding edge in the middle of supporting surface and extends perpendicular to the supporting shaft thereby dividing the supporting surface into a first area and a second area. A first supporting frame (14) is pivotally supported on the supporting shaft over the first area. A first rotating shaft (25) is rotatably supported by the first supporting frame parallel with the supporting shaft. A first upper feeding roller (26, 27) is fixed on the first rotating shaft and forced to engage any page placed upon the first area. A second supporting frame (15) is pivotally supported on the supporting shaft over the second area.

Abstract: A plurality of lines are printed by the print head of a printer which is moved in a predetermined print direction on a sheet placed on a planar supporting surface wherein the sheet is fed perpendicular to the print direction. The print head is slidably mounted on a guide bar which is supported by a frame parallel to the sheet supporting surface so as to permit moving the lower end of the print head upwardly and downwardly relative to the support surface. The frame is biased in the downward direction normally. During non-print operation, a driving lever moves the frame upwardly to raise the print head to an initial position spaced above the support surface by a predetermined distance where it is maintained. During a print operation, the driving lever engages the frame to drive it upwardly or downwardly with the upward movement against the bias force.

Abstract: A recording and/or reading head has a recording and/or read nose and is movably mounted. The head is preloaded against a record carrier with first and second preload values. A sensor device senses and maintains the distance between the record carrier and the nose constant. The preloading structure includes a spring loaded cam operated mechanism acting between the head and the record carrier via a spring loaded wheel secured to the head, the wheel engaging the record carrier. A switching mechanism switches the apparatus between the first and second preload conditions. The apparatus can print or operate with documents of different thicknesses.

Abstract: Two print heads each having a plurality of print elements arranged over a print width to allow printing of a predetermined area by a print scan operation are arranged one for each one of adjacent pages bordered by a seam line of a booklet along which a plurality of sheets of the booklet are bound. The print elements are non-impact type print elements such as thermal print elements.

Abstract: A self-leveling tranpsort for addressing envelopes in cooperation with a printer having a first link on each side of the transport, with transport drive and idler roller shafts journaled at the opposite ends, an endless transport belt stretched across the drive and idler rollers, a second link pivotally attached to each first link through the idler roller shaft, the second links being pivotally attached to the printer frame at the second links other end, a third cross link pivotally attached to each second link between the link ends, the second links having a slide block with oversized aperture at the opposite end through which the drive roller shaft fits, the slide blocks being slidable vertically up and down with springs to bias the slide blocks and the transport upwardly so that when the thickness of the articles increase, the first, second, and third links respond to draw the transport down while retaining the transport level.
