Definitions
- the invention relates to printers such as are found in particular in fax machines.
- the invention relates to printers using a ribbon as a printing consumable.
- printers can be printers by thermal transfer or by sublimation, that is to say printers in which are printed by ink transfer from a ribbon using a thermal source, comprising a thermal print head or again, by way of example, of mechanical transfer printers comprising a needle print head.
- the printing ribbon used in roll, includes a support film in polyethylene coated with a layer of hot-melt ink.
- a roll food supplies virgin ribbon which is entrained, concomitantly with a print medium, in front of the thermal print head provided heating elements under activation of which ink is transferred from ribbon on the support, then the ribbon is rewound on a take-up roller intended to be thrown away. The ribbon is thus driven from the food roll to the take-up roller, passing in front of the print head.
- Document US 4,616,236 teaches a method for printing on X format print media images smaller than X / 2, at using a printing ribbon supporting a succession of ink ranges in X format.
- To print two print media in succession concomitantly drives the support and the printing ribbon in front of a head in the forward direction, and we print the two supports using the two halves of the same ink pad, respectively, driving the ribbon backward between successive prints of two supports.
- the format of the image to be printed must be less than half the size of the ink pads.
- the present invention first proposes to save printing ribbon whatever the format of the image to print.
- the invention relates to a method for printing successively, by ink transfer, a plurality of images on at least one support printing using a printing ribbon, a process in which, for the printing of each image, we train concomitantly the ribbon and the media in front of a printhead in a forward direction, and between two successive image prints, we drag the ribbon, in the reverse direction, the along a displacement such as one prints the following image using at least of a remaining printing area of a portion of ribbon previously used, process characterized by the fact, when printing a plurality of print media shifted by a spatial interval determined the bottom edge of each of the supports from the top edge of the next support, we drive the ribbon in the return direction, between successive impressions of support, along at least equal displacement said spatial interval.
- ink transfer is meant both the thermal transfer stricto sensu that sublimation, i.e. any ink transfer process by a thermal source of a printing ribbon on a support printing.
- the ribbon is unrolled of a food roll and we rewind it on a take-up roll, and between two successive prints, unroll it from the take-up roll and rewinds on the food roll.
- the invention also relates to a device for printing successively, by ink transfer, a plurality of images on at least one support printing using a printing ribbon, for the implementation of the method according to claim 1, comprising a housing for receiving a food roll of printing ribbon, a receiving a print ribbon take-up roll, one head printing, ribbon drive means arranged to drive the ribbon, in a forward direction, from the food roll to the take-up roll passing in front of the print head, means for driving the support arranged to drive the support in the forward direction in front of the head printing, and means arranged to drive the ribbon in the direction return, device characterized in that it comprises a single motor ribbon drive in the forward direction and in the reverse direction, wheel mounted free, to drive the food roll in the return direction, rotary drive means, mounted freewheeling, to drive the take-up roller in the forward direction, means for slowing down the drive of the food roller driven in the forward direction and means to brake the drive of the take-up roller driven in the return direction.
- the printer belongs to a fax.
- This is a thermal transfer printer including a thermal print head 1, a housing for receiving a roll ribbon food, receiving housing for a take-up roller ribbon, a magazine 5 for the input of print media to be printed, in the kind of reamed sheets of paper, a sheet outlet store after printing, a separation edge 4 and a mechanism 7 for printing ribbon 10 and a backing sheet printing.
- Both rolls, food and receiver are supported by two respective axes 2 and 3 which are both mounted free in rotation.
- a pinion 38 and a pinion 39 are fixed respectively on the axis 2 and on axis 3.
- the printing ribbon 10 (FIG. 3) comprises a polyethylene film 11 supporting a printing layer 12 here comprising a plurality of hot-melt ink pads 12a, 12b, 12c in cyan, magenta, yellow colors and black, arranged one next to the other along the length of the ribbon 10.
- the film 11 also supports a marking area 13 located on the along the longitudinal edge of the tape 10, in the vicinity of the layer 12, and containing a plurality of positioning indications, here black bars, placed side by side along the edge of the ribbon 10, at regular intervals.
- the drive mechanism 7 is also intended to drive the ribbon 10 in the reverse direction in front of the thermal head 1, delivering it of the take-up roller and rewinding it on the food roll, as this will be explained later.
- the forward direction of a pinion, a roller or any other rotary element of the printer is the direction of rotation of this element corresponding to the direction in which the ribbon is driven from the roll food with the take-up roller and / or in the sense that a sheet is driven from the input magazine 5 to the output magazine 6.
- the return direction is of course the opposite direction to this forward direction.
- the mechanism 7 includes a single motor 18 for rotational drive of a motor shaft 19, in the forward direction and in the reverse direction, and a system gear for driving the ribbon 10 and a support sheet printing.
- the gear system includes in particular, for the drive of the ribbon 10 in the forward direction, a pinion 33 mounted in free wheel.
- the pinion 33 engages, via a differential, with the pinion 39 of the axis 3 roller support receiver and is arranged to be rotated in the forward direction by the motor shaft 19, via a set of drive pinions not shown.
- the take-up roller Under the action of the rotational drive in the forward direction of the motor shaft 19, the take-up roller is thus intended to be driven in rotation in the forward direction, via the pinion set intermediate, pinion 33 and pinion 39.
- the gear system For driving the ribbon 10 in the return direction, the gear system includes two pinions 29 and 32 integral and coaxial.
- Pinion 32 mounted in freewheel, meshes with the pinion 38 of the axis 2 support of the food roller and the pinion 29 meshes with the pinion 28 meshed itself a pinion 23.
- This mounted free to rotate, is meshed with a pinion 34 arranged to be rotated by the drive shaft 19, by through the set of drive gears not shown.
- the pinion 34 and the pinion 33 are coaxial.
- the food roller is intended to be rotated in the return direction, under the action of the rotary drive of the motor shaft 19 in the return direction, via the gear chain comprising the intermediate gear set and the gears 34, 23, 28, 29, 32 and 38, as will be explained later.
- the gear system For driving a printing sheet, the gear system includes an axis 24 for loading the sheet, adjacent to the input magazine 5, and an axis 25 for ejecting the sheet, adjacent to the outlet magazine 6.
- the axis 24 and the axis 25 respectively support loading rollers and ejection rollers.
- a pinion 40 and two coaxial and integral pinions 41, 35 are respectively fixed on the loading axis 24 and on the ejection axis 25.
- the two pinions 41 and 40 are meshed with a pinion 26.
- the drive pinion 23 is thus arranged to drive the axis 25 support of the ejection roller in the forward direction, via the pinion 35, and, under the action of the rotational drive of the pinion 41, the pinion 26 is intended to be driven in rotation and to drive itself in rotation in the direction go the axis 24 support of the load rollers, via the pinion 40.
- the axis 25 of the ejection roller is mounted freewheeling so that it cannot to be rotated only in the forward direction corresponding to the direction ejection, which avoids any risk of inadvertent loading of a sheet by the outlet store 6.
- Two non-return systems 30, 31 are mounted respectively on the pinion 38 of axis 2 of the food roller and on the pinion 39 of axis 3 of the roller receiver.
- the non-return system 30 of the food roller is intended for apply a resistant torque to the pinion 38 when the latter is driven in rotation in the forward direction.
- the non-return system 31 of the take-up roller is intended to apply a resistant torque to the pinion 39 when it is driven in the return direction. Thanks to this, the ribbon is always tense when it is driven in the forward direction or in the reverse direction.
- the printer further includes a page storage memory 14 image of received faxes, a block 15 for digital analysis of the images of fax stored as data in memory 14, a sensor 16 for detecting sheets of print media, a sensor 17 for detection of indications of positioning of the printing ribbon 10 and a control block 21, in this case a microprocessor, to which all the electrical and electronic components of the printer (head 1, sensors 16-17, block 15, motor, etc.) are connected.
- the thermal head 1 is here arranged to print the images line by line.
- the printing line of the thermal head 1, the virtual line 8 along which the thermal head 1 prints the lines successive of an image on a printing sheet scrolling in front of it.
- the sensor 16 is provided for detecting the presence of a sheet to be printed passing through the printing line 8.
- the sensor 17 is intended to detect the indications for positioning the printing ribbon 10 when the latter passes through the printing line 8.
- image line and "empty image line” are intended to denote respectively a line containing, in whole or in part, image points and a line without image points.
- a "portion of ribbon previously used” means a portion of the ribbon 10 passed in front of the print head 1, in the forward direction, in other words after a print pass.
- the printer further comprises a man-machine interface 20 with an input keyboard and a display screen
- the input keyboard includes an economical print button for controlling economical printing of images in memory 14, as well as a normal print key to print in mode normal.
- the images to be printed which are here image pages, are stored under form of data in memory 14.
- the motor shaft 19 is rotated in the forward direction by the motor 18 and drives the pinion 33, via the set of pinions previously mentioned intermediary.
- the pinion 33 drives itself in rotation axis 3 of the take-up roller, and therefore the take-up roller itself, in the forward direction, via the pinion 39.
- the pinion 23 Under the action of the drive of the motor shaft 19, the pinion 23 is driven in rotation, in the forward direction, through the set of gears and the pinion 34.
- the pinion 23 rotates in the forward direction, the roller writing 27, through its pinion 28, as well as pinion 41 by through the pinion 35.
- the pinion 41 rotates the pinion 26 which itself drives the pinion 40 of the axis 24 of the loading roller, in the forward direction.
- the ejection roller 25 and the loading roller 24 are thus rotated respectively in the direction of ejection and in the direction of loading.
- the food roller is rotated by the effort of traction exerted by the tape 10.
- the non-return system 30 applies a resisting torque on pinion 38 of axis 2 of the food roller, so that the rotation of the food roller is slowed down.
- the food roll thus rotates slower than the take-up roller and, as a result, the ribbon 10 tightens.
- a print sheet 100 is driven in the forward direction from entrance store 5 to exit store 6, passing in front of the head thermal 1 and, concomitantly, under the action of the rotation of the roller receiver and food roll, the ribbon 10 is driven in the direction go from the food roll, from which it is unwound, to the take-up roll, on which it is wound, passing in front of the thermal head 1.
- the sheet 100 and the ribbon 10, concomitantly trained in front of the head thermal 1, are pressed against it by the writing roller 27 and, under the activation of the heating elements of head 1, ink is transferred from ribbon 10 on sheet 100 and the image page is thus printed, line by line, on sheet 100.
- the analysis block 15 examines the image pages contained in the memory 14 in the form of data.
- top and bottom of an image page that is to say the top and bottom of the page, are by definition the parts of the page respectively printed successively by the head thermal 1.
- the block 15 For printing each of the successive image pages to be printed, the block 15, under the control of control block 21, examines, from top to bottom, the successive lines composing the page to be printed. For each line, the block 15 determines if it is a picture line, and therefore if it is a line to print in whole or in part, or if it is an empty line of image, in order to deduce if the page to be printed contains an upper zone, a band upper image void. If applicable, block 15 counts the number of empty image lines making up the empty image top area and, each line having a given height, evaluates the height of the empty upper area image.
- height is meant the dimension along the direction perpendicular to that of the lines making up the image page.
- the analysis block 15 For printing each of the successive pages, except for the first page, the analysis block 15, under the control of the control block 21, also examine, from bottom to top, the lines making up the image page previous page (i.e. the previously printed page), kept in the memory 14. Block 15 determines for each line, whether it is a line image or if it is an empty line of image in order to deduce if the page previous contains an empty image bottom area. If applicable, the block 15 counts the number of empty image lines composing the lower zone blank image and, each line having a given height, evaluates the height of the bottom empty image area.
- the printer drives one after the other two print sheets in front of thermal head 1, shifting one of the other of an "interpage". This is a determined spatial interval from which shifts the lower edge and the upper edge respectively by two sheets successively driven in front of the thermal head 1 for printing. A such interpage consumes an equivalent length of ribbon.
- block 15 evaluates a rewinding length, i.e. a length of tape that should be rewound around the food roll. For this, block 15 add, if necessary, the height of the interpage between the sheet previously printed and the sheet to be printed, the height of the area upper blank image of the page to print and the height of the area lower image void from the previous page, and subtracting from that a predefined tolerance height.
- a rewinding length i.e. a length of tape that should be rewound around the food roll.
- the motor shaft 19 between successive prints of two image pages and under the control of the control block 21, is rotated in the direction return by the motor 18 until the ribbon 10 of the take-up roll is unwound, which is simultaneously rewound on the food roll, estimated rewinding length.
- the take-up roller is rotated in the return direction, under the tensile force exerted by the tape 10.
- the non-return system 31 applies a resistant torque to the axis 3 roller support receiver so that it is braked and turns slower than the roller food. Thanks to this, the ribbon 10 is well tensioned during its rewinding on the food roll.
- the sensor 17 detects and counts print ribbon positioning bars 10 passing through the printing line 8 of the thermal head 1 and, the bars being separated from each other by a given and fixed interval, evaluates the length of which the ribbon 10 is effectively rewound.
- the control block 21 commands the stop motor 18.
- block 15 would convert the height rewind rated in number of revolutions of motor 19 and this one would rotated in the reverse direction substantially by the number of turns thus evaluated.
- the printer comprises, in addition to the elements described above, a working memory intended to contain the positions of printing lines and unusable lines of previously used tape portions as well that the positions of image lines and empty image lines of pages image to print.
- positions of the lines of the ribbon are defined by relation to the print line of the writing head and the positions of the lines of the image page are defined relative to the top line of the page to to print.
- print lines and "unusable lines” mean here respectively designate blank lines of ribbon 10 and lines of ribbon already used, in whole or in part, for printing image points.
- the digital analysis block analyzes the lines of this page image.
- the unusable lines and the printing lines of the portion of ribbon used correspond respectively to image lines and lines image blanks from the image page previously printed with this portion of ribbon.
- the digital analysis block compares, by their respective positions, the image lines of the page examined and the remaining print lines of the portion of ribbon previously used, to determine if the lines image of the page under review can at least in part be printed at using the remaining print lines from the ribbon portion previously used, separated from the portion of ribbon not yet used by at least one unusable line.
- the digital analysis block determines the length of ribbon rewind, i.e. the length of ribbon along which it should drive the tape in the return direction, by unwinding the roll receiver and rewind on the food roll, so as to position suitably the printing ribbon in relation to the printing line of the thermal head.
- the ribbon is correctly positioned when the lines of the remaining portion of ribbon previously used, for printing image lines of the page to be printed, go to across the thermal head printing line for printing these image lines on a print media sheet.
- FIG. 4 illustrates such an example in which an element is first printed oval 101 then a triangular 102 element using the portion of ribbon already used.
- Arrows 36 and 37 indicate respectively the forward direction and the return direction of the ribbon.
- the oval element 101 is printed in negative during a first ribbon printing pass in the forward direction 36 in front of the thermal head, then the ribbon is driven backward 37 and, within one second ribbon printing pass in the forward direction 36 in front of the thermal head, the triangular shaped element 102, located in FIG. 4 upstream of the oval-shaped element 101 in the forward direction 36 is printed.
- a line of a portion of ribbon previously used is a print line, in other words a line can be used to print an image line, if this line of the ribbon is blank.
- lines of the printing ribbon are used slightly depleted in ink to print image lines.
- the block analysis tool assesses the ink surface density of each line of the portion of ribbon previously used, compares it to a predefined threshold and, in the case where the density evaluated is greater than the threshold, the analysis block considers that said line of the ribbon is a printing line, usable for print an image line.
- the digital analysis block evaluates the density of image points of the image line previously printed using this ribbon line.
