Abstract
A printer for printing onto a substrate includes a substrate feed mechanism configured to secure the substrate during printing and a print mechanism configured to print on the substrate. A transceiver is configured to transfer power through a non-physical link to a radio frequency (RF) circuit carried on a printer supply to thereby power the RF circuit. The transceiver also responsively receives printer supply data through a non-physical link from the RF circuit.
Description




The present invention relates to electronic printers and laminators of the type used to print or laminate a substrate. More specifically, the present invention relates to the transfer of data between the electronic printer or laminator and supplies which are used during operation of the printer.




Electronic printers are used for printing onto the substrate. Examples of such printers include bubble jet, dye sublimation, impact, and laser printers. In general, all such printers require some type of supply for their continued operation. Examples of such supplies include ribbon, ink, toner cartridge, print medium, overlaminate film, cleaning tape, cleaning roller, etc.




U.S. Pat. No. 5,755,519, issued May 26, 1998 and entitled “PRINTER RIBBON IDENTIFICATION SENSOR” describes an identification system for a hub which carries a ribbon. This allows the printer to receive information from the ribbon core such as the type of ribbon or the particular section or panel of ribbon being printed. The information is encoded magnetically or through bar coding. However, the information carried on the ribbon is fixed and can not be changed during use.




SUMMARY OF THE INVENTION




A printer or laminator for printing or laminating onto a substrate includes a substrate feed mechanism configured to secure the substrate during printing and a print mechanism configured to print on the substrate. A transceiver is configured to transfer power through a non-physical link to a radio frequency (RF) circuit carried on a printer or laminator supply to thereby power the RF circuit. The transceiver also responsively receives printer or laminator supply data through a non-physical link from the RF circuit.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS




In

FIG. 1

, a schematic representation shows a printer ribbon


12


provided from a supply roll or core


14


that would include the alterable, embedded identification tag or circuit (ID tag) shown generally at


15


. The ribbon


12


, for purposes of illustration, extends to an optional take up roll


16


, the core of which also could have an ID tag if desired. The ribbon


12


passes over a printing platen


18


that is rotatably driven by a motor


20


, under central control from a printer controller


22


, The take up roll


16


can be driven by a motor


17


if desired and that can be synchronized with a drive of the roller


14


by the printer controller


22


. A card or substrate


24


to be printed on is driven forward and backward on suitable rollers


26


with driver motors


30


that synchronize it with the movement of the individual color panels or frames that repeat in a sequence or group on the ribbon


12


.




A conventional thermal print head


34


can be supported on a printer frame


36


, relative to platen


18


. The printing operation is synchronized through controller


22


using a card sensor


32


so that the card


24


would be printed appropriately. The card


24


will come from a card supply and card feeder


23


in a conventional manner using the powered rollers


26


driven by stepper motors


30


as controlled by the printer controller


22


. The controller


22


also controls motor


20


for platen


18


.




In

FIG. 2

, a schematic arrangement of a ribbon core, ID tag, transmitter/receiver (sensor) and the controls is shown. The supply roll


14


is illustrated schematically, and it shows the ribbon or web


12


coming off the supply roll.




A Radio Frequency transmitter/receiver circuit head or antenna (or read/write circuit, head or antenna)


42


is positioned adjacent to one end of the ribbon supply roll


14


, and the Radio Frequency ID tag


15


is illustrated schematically as being embedded in the core


14


A of the ribbon supply roll. The antenna


42


is positioned closely adjacent to the core


14


A of the ribbon supply roll


14


, so that it can transmit to and receive from ID tag


15


low power Radio Frequency (RF) signals. However, with more powerful signals or more sensitive electronics, the spacing can be any suitable distance.




At the opposite end of the ribbon supply roll


14


, an encoder system for encoding supply roll rotational information is illustrated at


50


. This type. of encoder for roll position can be used for cooperating with the ID tag information to provide records or information as to ribbon usage and the like back to the ID tag so that when the ribbon supply roll is removed from a printer, and subsequently placed in another printer, information such as the number of prints remaining, and the number of prints used can be provided, as well as ensuring that the position of the roll is proper when installed. The encoder


50


is well known and includes an encoder wheel


55


that has a plurality of apertures


57


that will transmit light. The apertures


57


are separated by opaque or light blocking segments. The wheel


55


is supported for rotation with the ribbon supply roll


14


. A suitable bearing arrangement as shown at


59


can be used if desired. Wheel


55


is mounted on a shaft that has a drive coupler


60


thereon, which is provided with a suitable key that will interfit with an end slot


64


in the core


14


A. The wheel


55


is driven by the ribbon supply roll


14


when the drive parts are engaged.




An optical sensor illustrated schematically at


51


has a light source


53


and a receiver


54


. The receiver


54


as shown is a light sensitive diode, so that each time an opening


57


moves between the light source and the receiver there is a pulse that indicates the rotational position of the ribbon supply roll


14


. The number of pulses received by circuitry


65


indicates the amount of rotation, and the circuit keeps a count of the number of pulses. These count signals are provided to a microprocessor


70


that forms part of the printer controller


22


. Of course, more complex techniques can be used, for example, if the ribbon undergoes bidirectional movement.




The printer controller


22


can include an input circuit shown at


72


that can provide both manual inputs for printer control of the printer head


34


, and signal inputs from the ID tag, or a key card input directly to the microprocessor.




One of the features of the present invention is that the printer controller


22


can have a key card input circuitry


74


in which a programmed key card or “mart” card key


76


can be inserted to ensure that the printer, and thus the printer ribbon, will not be operated unless the correct key card has been inserted and the correct algorithm interpreted for unlocking or enabling the printer controller


22


. The use of a smartcard is set forth in U.S. application Ser. No. 09/263;343, filed Mar. 5, 1999 and entitled “SECURITY PRINTING AND UNLOCKING MECHANISM FOR HIGH SECURITY PRINTERS” which incorporated herein by reference. Key card inputs are known in the field, and can comprise a number of different signals that can be used in an algorithm to ensure that the printer controller would be unlocked or enabled only when the appropriate card is inserted. The card also can include information that can be correlated to a checking of the signals from the ID tag or controller and from the key card by the Radio Frequency transmitter/receiver


42


to insure that the appropriate ribbon has been inserted into the printer before the printer controller is unlocked for use. This can be used to lock the printer and ribbon or laminate so that only the proper laminate, in the proper order can be used in a high security implementation. This can also be used to match a person with a password to a ribbon.




Additionally, the ribbon information that is coded onto the ribbon by the bar codes or similar indicia


58


and read from the infrared sensors


56


can be fed directly to the microprocessor


70


of the printer controller so that a wide range of information is available to the microprocessor


70


before enabling the printer. One such technique is described in U.S. patent application Ser. No. 09/309,391, filed May 10, 1999 and entitled “ID CODE FOR COLOR THERMAL PRINT RIBBON which is incorporated herein by reference. The microprocessor can thus provide various information back to the Radio Frequency transmitter/receiver or read/write antenna


42


. Additionally, the microprocessor can verify the ribbon against the various settings of the printer and prevent operator error.





FIG. 3

is a schematic representation of a typical RF embedded circuit ID tag


15


, which includes a small wire loop antenna


90


, and a chip


92


on which circuit components are provided The chip


92


can include memory such as that shown at


93


, and a transmitter/receiver circuit


94


of very low power capacity. The memory can act as a counter and be decremented for each print made, for example so the prints remaining are known, and a binary code unique to the ribbon can be stored.

FIG. 3

shows the read/write circuit antenna


42


positioned adjacent to the ID tag


15


. The antenna


42


has an antenna portion


97


that can transmit and receive RF signals to and from the antenna


90


on the circuit for the ID tag


15


. The antenna or read/write head


42


includes circuitry


98


that provides signals to and from the microprocessor


70


. The transmitter/ receiver or read/write antenna


42


can provide signals that will energize digital components on the ID tag for transmission of data from the counters or memory


93


back to the circuit


98


on the antenna


42


, which indicates the status of the ribbon on core


14


A, and some identification parameters, such as the serial number, lot code, date code, password or errors. The information can indicate the type of ribbon on the roll, or include a code which permits operating with only a specific printer or group of printers and similar information.




It should be noted that the transmitter/receiver


42


can be a fixed installation, as stated, that would transmit through the packaging used for the ribbon, when received from a supplier, so that the ID tag


15


, when using RF transmissions, could be preprogrammed with identification as to type of ribbon and the like, subsequent to packaging without breaking the package open, either by the printer manufacturer or by a distributor. The type of ribbon can be coded in, including information about the density of the dye in individual panels and when the ribbon is placed into a printer. This information can be read out by the transmitter/receiver


42


and provided to the printer controller microprocessor


70


to adjust the print head for the heat level needed for different densities of panels of ribbon to improve image quality. When ribbon information is correlated with the encoder circuitry


50


information through the microprocessor


70


, the information about the number of prints that remain can be written to the ID tag


15


at the end of the printing cycle if the ribbon is to be removed from the printer, so that the next time that the ribbon is placed into a printer the exact number of prints that are left is known. The spool or roll size changes as the ribbon is used and the torque and tensioning of the ribbon roll drive motors can be changed to adjust for decreasing ribbon spool size and weight to improve image quality.




Further, the printer


34


and the controller


22


can provide date code information that can be encoded into the ID tag


15


, using antenna


42


so that it will be known if the ribbon shelf life has expired. The ID tag


15


can be programmed by antenna


42


with password information so that particular key card


76


could have to have a password that must match with a password on the ID tag


15


for the ribbon before the printer would be enabled. Thus a particular key card would have to be inserted before the printer would work with a particular ribbon. This is especially useful if there are custom holograms used for laminating the card. This is advantageous because it provides an additional level of security when used in sensitive installations such as military installations or printing driver licenses. The ID tag will further permit determining whether or not a ribbon can be used with any particular printer. The card


76


further can be used in connection with the ID tag


15


so that only a set number of prints can be issued by a single card


76


, which information is presently used on many cards, limiting the uses to such set number. Other features can include information from a printer programmed into the ID tag


15


which indicates the type of printer used last. This information could be erased and reentered when the print ribbon is again used. The ID tag


15


is preferably RF programmable and readable.




When coordinated with the information about the individual frames received from the infrared sensor


56


, identification, positioning, and operations of the ribbon can be completely controlled by the printer.




A further modified form of the invention is illustrated in

FIG. 5

, where a core


14


A is provided with a light sensitive circuit ID tag


80


that has light sensitive circuit elements that are in line to receive light or radiant energy from a light signal source circuit or signal circuit head


82


, that transmits light with sufficient intensity to provide a signal to change a state in the tag


80


to record information. The light transmitted can be in the infrared range or in the visible light range. The light signal source also can receive signals from the ID tag


80


if the tag


80


is powered to provide light. A controller


84


controls the source or head


82


and can provide phase shift inputs from source


86


, control of frequency from source


88


, pulsing codes from source


90


and it can control intensity.

142


carried on supply


144


. Transceiver


140


is configured to transfer power through a non-physical link to a radio frequency circuit carried in RFID tag


142


. This causes RFID tag to responsively transmit data over a non-physical link to transceiver


140


. Transceiver


140


includes an antenna


146


having a coil


148


and a capacitor


150


. Antenna

couples to a radio frequency amplifier


152


which receives supply data from tag


142


and provides the supply data to controller

can be any type of supply which is used with electronic printer


120


. For example, supply


144


can comprise ribbon, intermediate transfer film, hologram material, toner, cleaning tape or ink such as for use with an ink jet or other type of printer. The RFID tag


142


can be any such RFID tag such as those which can be purchased commercially. One type of RFID tag is available from TEMIC Semiconductors a division of ATMEL located in San Jose, Calif. For example, the TEMIC Model No. TK5550 is one such RFID tag.

is a simplified block diagram showing RFID tag


142


coupled to printer supply

includes an antenna


160


formed by an electrical coil which couples to a power supply


162


and transceiver circuitry

. A controller


166


couples to memory


168


and to transceiver circuitry


164


. A tuning capacitor


170


is also provided in series with the coil


172


. In operation, coil


148


of transceiver


140


is powered by RF amplifier


142


such that an inductive coupling occurs with coil


172


of RFID tag


142


when the two are in close proximity. However, in another embodiment a sufficiently strong signal or sufficiently sensitive circuitry are used whereby the tag


142


can be spaced a distance from coil


172


. In one embodiment a 125 KHz signal is used to drive coil


148


which then inductively couples to coil


172


.




Power supply


162


generates a stable power output used to power all of the circuitry within RFID tag


142


received through this inductive coupling. By modulating the signal, data can be transferred between transceiver


140


and RFID tag

and transceiver


140


. In another embodiment, an internal power source such as a battery is used to power tag


142


. In another embodiment, a physical connection to the printer or laminator is used to power tag


142


.




Printer supply


144


can be any type of supply which is used by printer


120


in the printing process. For example, if printer supply


144


is a ribbon which could be carried on a spool or in a cartridge, various data can be stored in memory


168


. This data includes the make and supplier of the ribbon such that operation of print head


124


can be optimized (i.e., the proper thermal printer head voltage can be optimized for a given dye carried on the ribbon) . Further, a date code can be stored in memory to monitor the aging of the ribbon or other material. A lot code and material code can be stored in memory


168


for use in optimizing printing. Information regarding the ribbon panel or ink jet ink quantity can be stored in memory


168


and updated during use of the ribbon or ink such that the total quantity of remaining ribbons or ink can be read by printer


120


and stored in the supply tag. Additionally, information regarding ribbon quantity can be used when adjusting web tension of the ribbon as it moves between a supply spool and a take-up spool or in the case of ink jet, adjust the motor control for the amount of ink weight. Ribbon panel size information can be stored in memory


168


and used to provide diagnostics if the ribbon panel size does not match the size of the substrate. A part number stored in memory


168


can be used for diagnostics and for reordering additional supplies.




If supply


144


is an intermediate transfer film, supplier, date code information, lot code and material code information can be stored in memory


168


as can film panel quantity information, film panel size and part number. Film thickness information stored in memory


168


can be used to adjust the print head or laminator for the correct heat transfer level and use in controlling web tension.




If supply


144


is hologram or an OVD (Optical Variable Device) supplier, date code, lot code and material information, film quantity, film panel size, material thickness and/or part number information can be stored in memory


168


as described above. Additionally, a private key for digital encryption can be stored in memory


168


and used as a security key to prevent unauthorized use of the material. For example, printer


120


will not be able to print unless the correct security key is received from the PC through bus


126


which is used to unlock the material using the private key stored in memory


168


.




If supply


144


is an ink jet ink supply or toner supply, supplier, date code, lot code and material information, ink/toner supply quantity and part number information can be stored in memory


168


. Supply


144


can also comprise a laminate material for a laminator and memory


168


can store information such as lot code and material information, date code, supplier, material thickness, size, quantity, lamination and characteristics in heating requirements or other information. Similarly, if supply


144


is a cleaning web for cleaning rollers in a printer or laminator, similar information can be stored in memory


168


. Additionally, memory


168


can contain the number of times the cleaning supply has been used such that an indication can be provided that the supply should be replaced.




If supply


144


comprises a substrate or print media, such as an identification card, memory


168


can be used to store information relating to the card size, thickness and substrate materials so that printing or lamination can be optimized for these materials. Additionally, memory


168


can be used to store coded security information fox an identification card. For example, a security code stored in memory


168


can read by other devices such as a security door and used to gain access to a secure location by using the identification card. This data can also be used to interlock with smart chip information carried on the identification card or other information printed onto the card.

. In various aspects of the invention, microprocessor controls web tension, print head heating and card movement based upon data received from an RFID tag


142


carried in supply spool


188


. Comparator


206


is used to prevent printing through interlock


208


if date information carried in RFID tag


142


indicates that the ribbon has degraded due to age. Alternatively, this information can be displayed in display


132


and the operator can make a decision whether to use the material.





FIG. 8

also illustrates an embodiment in which an RFID tag


142


is used in a laminator. In such an embodiment, element


124


comprises a heated roller or other heating device and is controlled by a laminator drive circuit. Temperature feedback can also be provided from the laminator. In such an embodiment, the memory


168


in the RFID tag


142


can contain information regarding parameters which effect lamination temperature. Such information includes, for example, lamination film type, lamination film supplier, thickness, width, age such as through a date code or other such information.




In yet another aspect of the present invention, the information is transferred from the supply to the printer (or from the printer to the supply) over a physical connection such as through electrical wiring. In such an embodiment, the supply include electrical contacts to which the printer makes electrical contact when the supply is coupled to the printer. In such an embodiment, the power for the tag can be provided over the electrical connection. In another embodiment, a single pair of electrical connections are provided which carry both power and data between the supply and the printer. Referring to

FIGS. 6 and 7

, in such an embodiment the output from controller


166


can be optionally sent through a transceiver


164


and through a direct connection to microprocessor


122


in the printer/laminator. The transmission can be in any suitable format, for example, a binary format or a modulated signal such as an RF signal. Another non-contact method is to use a magnetic field to transmit information. This can be accomplished by using a magnetic head instead of an RF antenna. In another example of a non-physical link, an optical connection is provided between the supply and the printer or laminator.
