The present invention is basically designed for use in a mobile communication terminal, such as a mobile communication terminal (i.e., mobile phone) incorporating a printer, and the present invention will be described with reference to these applications. However, those skilled in the art will appreciate that the present invention can be used for other types of portable terminals or non-portable terminals.

Cross-reference

The following patents or patent applications filed by the applicant or assignee of the present invention are incorporated into the present invention by cross-reference.

Some applications are listed by docket number. It will be replaced when the application number is known.

The assignee is a mobile phone, personal data assistants (PDAs) and other mobile communication terminals, with the ability to print hard copies of images stored or accessed by the terminal. (See US Pat. No. 6,405,055 (document # AP06US), filed Nov. 9, 1999). Similarly, the assignee also devised a digital camera with the ability to print a captured image with a built-in printer (see US Pat. No. 6,750,901, filed July 10, 1998 (document number ART01US)). . As the popularity of mobile communication terminals with digital cameras increases, the functions of these terminals are further improved by the ability to print hard copies.

Since these terminals are portable, they need to be miniaturized for the convenience of the user. Thus, any printer integrated into the terminal needs to maintain a small form factor. In addition, the additional load of the battery should be as small as possible. In addition, consumables (such as ink and paper) must be relatively inexpensive and simple to replenish. These factors strongly influence the commercial success or other circumstances of these types of products. With this basic design in mind, efforts are being made to improve and improve the functions of the terminals.

The assignee of the present invention has also developed a Netpage system for interacting with computer software using a printed interface and a proprietary stylus-shaped sensing device.

As described in detail in U.S. Patent No. 6,792,165, filed November 25, 2000, and U.S. Patent Application No. 10 / 778,056, filed February 17, 2004, document No. NPS047US. A page pen captures, identifies and decodes tags of coded data printed on the same surface as one page. In a preferred netpage implementation, each tag encodes a document's location and identity. By decrypting at least one of the tags and sending the associated location (or the finely analyzed location representing the high resolution location of the pen) and the identifier by the decrypted tags, the remote computer can determine the action to execute. Such an action may include, for example, remotely storing information for subsequent retrival, displaying a webpage via a computer or downloading it for printing, paying a bill, or placing a Netpage pen on a surface. You may recognize handwritten letters through where you are.

The foregoing and other applications are described in a number of netpage related applications cross-referenced by the present application.

When printing a netpage, the printer in the mobile terminal can print the netpage tags at the same time as the visible user information. The association between the tags and the information may already exist in the remote netpage server, such as when the printer prints a complete rendered page (including tags) provided by the netpage server or other computer. have. Alternatively, the mobile terminal can generate tags (or obtain them remotely) and define the association between the tags and the user information. The association is then recorded on the remote netpage server.

The problem with these options is that they require the mobile terminal to include netpage tag printing capability. This requires an additional row of print nozzles in the printhead and reduces the amount of ink that can be stored for non-tag use. This is not a problem for large mains-powered printers, but may be a problem for small form factor articles such as mobile communication terminals.

Alternatively, the mobile communication terminal may be configured to print on a print medium that is pre-printed with netpage tags. In that way the printer only needs to print the user information and records the association between the visible information and the preprinted tags.

One way of doing this is a netpage sensing device that scans a page as it prints a page to determine the locations of various elements of user information for the tags and the content of at least one of the tags. Is to use This requires that the printer include a netpage detector, which is rather bulky and requires additional processing power for use in mobile applications. Even if a netpage sensing device is provided to allow the mobile terminal to act as a netpage pen in a more general sense, the parameters of the coded data before the user inserts the print media by separately scanning a portion of the preprinted media. It is not desirable to determine.

It would be desirable to overcome the problem of relevant user information to be printed on at least partially pre-printed media with netpage tags.

It is important that any mobile terminal that incorporates a printhead and media feed assembly does not significantly increase the overall size and compact form factor of the currently available mobile terminal. The use of a single media feed roller in a mobile communication terminal equipped with a printhead considers a compact design. However, the feed roller should be just in front of the print head (with respect to the medium feed direction) so that the trailing edge of the medium is conveyed past the print head by momentum. For this reason, the speed of the paper feed roller changes during printing of the media paper. First, the additional load reduces the angular velocity when the leading edge of the media paper first engages the paper feed roller. Once frictional engagement is established between the roller and the medium, the angular velocity increases again. If the printhead comes closer to the paper feed roller, the roller is further accelerated when the leading edge is being printed. If the print engine controller (PEC) estimates that the roller speed is constant, visible artifacts appear printed on the leading edge of the media. By having the PEC detect the longitudinal position of the media relative to the printhead, the PEC can then induce differential speed of the media and also adjust the operation of the nozzle according to some variation to remove the print from the print. have.

The print engine controller (PEC) needs to control the injection of the print data of each line from the nozzle with a line sync signal. The line sync signal essentially indicates when the card moves along the feed path as needed and when the next line of print can be ejected from the nozzle. There is another way of generating the line synchronization signal. However, in order to minimize components and reduce all form factors, the medium may be encoded with clock data that is selectively sensed and used alternately to obtain a clock signal that generates a line synchronization signal. The clock data sensor is located very close to the print head (the media inlet side), and cannot pass the clock data on the trailing edge of the medium as it passes toward the print head.

By configuring the sensing terminal to read clock data in duplicate, once before the printhead and then again behind the printhead, a line sync signal can be generated from the leading edge to the trailing edge of the medium.

In a preferred embodiment (described in more detail below), the print medium is pre-printed in tags, and the printer module 4 is matched with the tags to be visible on the page 6. Print the information. In other embodiments, the netpage tag is printed by the printer module over the page 6 according to other information. The tags can be printed using visible ink, such as the one used to print visible information, or using infrared ink or other invisible ink.

The information printed by the printer module 4 is a mobile user data stored in the phone 1 (phone book (phonebook) and appointment data (appointment data) the included), or or received through the mobile communication network or a Bluetooth (Bluetooh ^TM Text and images received from other devices through a communication device, such as an < RTI ID = 0.0 > and < / RTI > or infrared transmission. If the mobile phone 1 comprises a camera, the printer module 4 is configured to print the captured images. In a preferred form, the mobile phone module 2 provides at least basic editing capabilities to the captured image before printing, which enables cropping, filtering or addition of text or other images.

The construction and operation of the printer module 4 is described in more detail below in the context of various types of mobile communication terminals incorporating a printhead.

The netpage module 8 enables interaction between the page 10 containing the netpage tags and the mobile phone 1. The configuration and operation of the netpage pointer in the mobile phone 1 will be described in more detail below. Although not shown, the mobile phone 1 having the netpage module 8 may include a camera.

FIG. 3 shows a mobile phone 1 comprising both a printer module 4 and a netpage tag module 8. As in the embodiment of FIG. 2, the printer module 4 may be configured to print tagged or untagged pages. As shown in Fig. 3, when tagged pages 10 are generated (regardless of whether the tags are pre-printed or printed by the printer module 4), the netpage tag sensor module 8 is final. Can be used to interact with the printed media.

A more detailed architectural view of the mobile phone 1 of FIG. 3 is shown in FIG. 4, wherein the components corresponding to the components shown in FIG. 3 are indicated by the same reference numerals. 4 shows only communication between various electronic components in the mobile communication terminal and omits mechanical characteristics. These characteristics are described in more detail below.

The netpage tag sensor module 8 includes a netpage image sensor monolithically integrated with a processor 12 that captures image data and receives a signal from a contact switch 14. The contact switch 14 is connected to the nib to determine when the nib (not shown) is pressed in contact with the surface. The sensor and processor 12 also output a signal that controls the illumination of the infrared LED 16 in accordance with the stylus pressed against the surface.

The image sensor and the processor 12 process tag information processed by a netpage pointer driver 18 that interfaces with a phone operating system 20 that is executed by a processor (not shown) of the mobile communication terminal. Outputs

The output to be printed is sent to the printer driver 22 by the phone operating system 20, which passes the output to the MoPEC chip 24. The MoPEC chip processes the output to generate dot data for supply to the printhead 26, as described in more detail below. The MoPEC chip 24 also receives a signal from the media sensor 28 indicating when the medium is to be printed in place and outputs a control signal to the media transport 30.

The CMOS tag image sensor 78 transfers the captured image data to the processor 74 and then processes it. The contact sensor 14 is brought into contact with the surface with sufficient force to shut off the switch in the contact sensor 14. Once the switch is shut off, the infrared LED 16 illuminates the surface, and the image sensor 78 captures at least one image and sends it to the image processor 74 for processing. Once processed (described in more detail below), the image data is sent to the mobile phone controller 36 for decryption.

In the alternative embodiment shown in FIG. 8, the tag sensor module 8 is replaced with a tag decoder module 84. The tag decoder module 80 includes all the components of the tag sensor module 8, but in addition to the hardware-based tag decoder 86, a working memory 90 and a program memory 80 for the tag decoder are added. have. This configuration reduces the computational load placed on the mobile phone controller as a corresponding increase in chip area compared to using the tag sensor module 8.

The netpage sensor module can be integrated in the form of a netpage pointer, which is a simplified netpage pen that is mostly suitable for activating hyperlinks. It is desirable to incorporate a non-marking stylus instead of the marking nib of the pen (described in detail later in this specification). This uses a surface contact sensor instead of the pen's continuous force sensor and is not suitable for capturing drawing and hand-writing, resulting in lower sampling rates. It is desirable to work. Netpage pointers are less expensive to implement than netpage pens, and tag image processing and tag decoding can potentially be executed by software without hardware support, depending on the sampling rate.

Various aspects of the present invention may be implemented in any of a number of mobile communication terminal types. Several other terminals have been described herein, but for the sake of brevity, the detailed description focuses on mobile communication terminal embodiments.

Mobile phones MOBILE PHONE )

One preferred embodiment is a 'candy bar' mobile communication terminal of a non-netpage function in the form of a mobile phone shown in Figs. 9-14. The netpage functional form is described in a later paragraph of this specification.

Typically, the display is disposed in one of the body parts and the keypad is disposed in the other, so that the display and the keypad are positioned adjacent to each other when the terminal is in the closed position.

In yet another embodiment, the terminal may have two body parts that rotate or slide relative to each other. Typically, the purpose of this mechanical relationship between the first body portion and the second body portion is to prevent the display from being scratched and / or from accidentally activating the keypad.

The loudspeaker 144 is provided adjacent to the opening 272 of the front molding 104 to allow a user to hear sounds such as voice communication and other audible signals.

The main PCB 130 is also equipped with a color display 138 to enable visual feedback to the user of the mobile communication terminal. Transparent lens molding 146 protects display 138. In one form, the transparent lens is touch-sensitive (or omitted and the display 138 is touch-sensitive), so that the user is able to compare the icon displayed on the display 138 with the input text using a finger or stylus. Enable interaction.

The vibration assembly 274 also includes a motor that is mounted to the chassis molding 102 to drive a weight mounted eccentrically to cause vibration. Vibration is transmitted to the chassis 102 to provide tactile feedback to the user, which is useful in noisy environments where no ringing tones can be heard.

MoPEC  -Higher level ( MoPEC  - High Level )

The document to be printed must be in the form of dot data by the time it reaches the printhead.

Before converting to dot data, the image is composed of relatively high spatial resolution bilevel components (for text and line art) and relatively low spatial resolution contone components (image and background color). If). The binary level component is compressed in a lossless format, while the contone component is compressed according to a lossy format such as JPEG.

Preferred forms of MoPEC can be configured to be operable in either of two modes. In the first mode, as shown in Fig. 15, the image to be printed is received in the form of compressed image data. Compressed image data may arrive from the same or different sources as a single bundle of data or separate bundles of data. For example, text may be received from a first remote server and image data for banner advertisements may be received from other sources. Alternatively, either or all of the forms of data may be retrieved from local memory in the mobile terminal.

Upon receipt, the compressed image data is buffered in a memory buffer 650. Binary level and contone components are recovered by each decompressor as part of expand page step 652. This may be done in either hardware or software, as described in detail below. The recovered binary level and contone components are then buffered at each FIFO 654, 656.

The reconstructed contone component is neutralized by a halftoning unit 658, and then the compositing unit 660 synthesizes the binary level components throughout the dithered contone component. Typically, this will involve compositing text throughout the image. However, the system can also be operated in stencil mode, where the binary level component is interpreted as being a mask overlying the dithered contone component. Depending on what is selected as the image component for the area to which the mask is applied, the result can be a text filled with a mask for the image or an underlying image (or texture). The advantage of the stencil mode is that the binary level components are not dithered, which makes it possible to define sharp edges. This may be useful in some applications, such as defining text or printing text composed of colored textures.

After compositing, the obtained image is dot formatted (662), including arranging the dots in order for output to the printhead and taking into account any spatial or operational compensation issues, as described in more detail below. do. The formatted dots are then fed to the printhead for printing, as described in more detail below.

In the second mode of operation, as shown in FIG. 16, the contone and binary level components are received in uncompressed form by the MoPEC directly to the respective FIFOs 656 and 654. The source of the components depends on the application. For example, the host processor of the mobile terminal may be configured to generate reconstructed image components from a compressed version, or may be uncompressed from anywhere else, such as a communication port or mobile network described in more detail elsewhere. It may simply be arranged to receive the components.

As long as the binary level and contone components are in their respective FIFOs, the MoPEC performs the same operation as described with respect to the first mode, and therefore used the same numbers for blocks of the same function.

As shown in Fig. 18, the central data structure of the preferred printing architecture is a three-layer generalized representation, called a page element. The page element can be used to represent units that span from a single rendering element emerging from a rendering engine to the entire page of a print jop. 18 shows a simplified UML diagram of page element 300. Conceptually, a binary level symbol zone selects between two color sources.

MoPEC  Device-low level ( MoPEC  - Low Level )

The hardware components of the preferred MoPEC device 326 are shown in FIG. 17 and described in more detail below.

Conceptually, a MoPEC device is simply a SoPEC device that is optimized for use in a mobile phone in a low power, low print speed environment (ie, the cross-referenced application USSN 10 / 727,181 filed Dec. 2, 2003). Document number PEA01US). In fact, as long as power supply requirements are met, SoPEC devices can provide the required functionality of MoPEC. However, by limiting the battery power of the mobile terminal, it may be desirable to change the SoPEC design.

As shown in FIG. 17, from a high level perspective, the MoPEC consists of three separate subsystems: a central processing unit (CPU) subsystem 1301, a dynamic random access memory (DRAM) subsystem ( 1302 and print engine pipeline (PEP) subsystem 1303.

MoPEC has much smaller eDRAM requirements than SoPEC. This is mainly due to the fairly small print media that designs MoPEC to produce print data.

In one form, the MoPEC may be provided in the form of a standalone ASIC designed to be installed in a mobile communication terminal. Alternatively, the MoPEC may be integrated on another ASIC incorporating some or all of the other functionality required for the mobile communication terminal.

CPU subsystem 1301 includes a CPU that controls and configures all forms of other subsystems. This provides general support for interfacing and synchronizing external printers with an internal print engine. In addition, the use of QA chips also controls low speed communication for the QA chips (described elsewhere herein). The preferred embodiment does not use a QA chip in a cartridge or mobile communication terminal.

The CPU subsystem 1301 also supports CPUs such as General Purpose Input Outputs (GPIOs, including motor control), Interrupt Controller Units (ICUs), LSS masters, and general timers. Include multiple peripherals to help The USB block provides an interface not only to the mobile processor's host processor but also to external data sources on demand. The choice of USB as the communication standard is a matter of design preference, and other types of communication protocols, such as firewire, can be used.

DRAM subsystem 1302 accepts requests from blocks within the CPU, USB, and print engine pipeline (PEP) subsystems. DRAM subsystem 1302, in particular the DRAM interface unit (DIU), coordinates the various requests and decisions for which the request must gain access to DRAM. The DIU adjusts based on the configured parameters to allow all requesters sufficient access to the DRAM. The DIU also hides DRAM implementation details such as page size, number of banks, and refresh rate. As the printed pages are quite small, you will see that the DRAM is significantly smaller than in the original SoPEC device. Also, if the host processor can supply the restored print data at a sufficiently high rate, the DRAM can be made very small (128-256 kbytes). This is because there is no need to buffer the information value of the entire page before the start print.

The print engine pipeline (PEP) subsystem 1303 accepts the compressed pages from the DRAM and then compresses the compressed pages into binary level dots for a given print line that is supposed to have a printhead interface in direct communication with the printhead. Render The first stage of the page expansion pipeline is a Contone Decoder Unit (CDU) and a Lossless Bi-level Decoder (LBD). The CDU extends the JPEG compressed contone (typically CMYK) layers and the LBD extends the compressed binary level layer (typically K). The output from the first stage is a set of buffers: Contone FIFO Unit (CFU) and Spot FIFO Unit (SFU). CFU and SFU buffers run on DRAM.

The second stage is a Halftone Compositor Unit (HCU) that dithers the contone layer into halftones and synthesizes the binary level spot layer on the resulting binary level dithered layer.

Multiple compositing options can be implemented depending on the printhead in which the MoPEC device is used. Up to six channels of binary level data are generated from this stage even if not all channels exist on the printhead. For example, in a preferred embodiment, the printhead is configured to print only CMY with K being pushed into the CMY channels and IR omitted.

In a third stage, a Dead Nozzle Compensator (DNC) compensates for dead nozzles in the printhead due to color duplication and incorrect diffusion of dead nozzle data into surrounding dots.

The resulting binary level dot data (CMY in the preferred embodiment) is buffered and written to a set of line buffers stored in the DRAM via a Dotline Writer Unit (DWU).

Finally, the dot-data is reloaded from the DRAM and passed to the print interface via the dot FIFO. The dot FIFO receives data from a Line Loader Unit (LLU) at a system clock rate, while the Printhead Interface (PHI) removes data from the FIFO and sends it to the printhead. send.

The amount of DRAM required will vary with the specific implementation of MoPEC (including the system that implements it). In this regard, the preferred MoPEC design can be configured to operate in one of three modes. It is contemplated that all of the modes available under the preferred embodiment may preprocess the received image data in some way. Preprocessing includes, for example, color space conversion and scaling if necessary.

In the first mode, the image data is reconstructed by the host processor and supplied to the MoPEC and delivered directly to the HCU. In this mode, CDUs and LBDs are efficiently bypassed, and the recovered data is provided directly to the CFU and SFU and passed through to the HCU. Since restoration is performed outside NoPEC and the HCU and subsequent hardware blocks are optimized to do its job, the MoPEC device can be clocked relatively slowly, so there is no need to specifically power up the MoPEC CPU. As a guide, a clock speed of 10 to 20 MHz is suitable.

In a second mode, the image data is supplied to the MoPEC in compressed form. First, this requires a minimum of about 256 kbytes (although twice as much) of the increase in NoPEC DRAM. In the second mode, CDU and LBD (and their respective buffers) are used to perform hardware reconstruction of the compressed contone and binary level image data. Again, since these are hardware units optimized to execute the task, the system can be clocked relatively slowly, so there is no need to specifically power up the MoPEC processor. However, a disadvantage of this mode is that the hardware CDU and LBD are somewhat inflexible. These are optimized for special restorations, so in the preferred embodiment they cannot be largely reconfigured to carry out other restorations.

In the third mode, the CDU and LBD are bypassed again, but the MoPEC still receives the image data in compressed form. The restore operation is executed by software by the MoPEC CPU. If the CPU is a general purpose processor, the CPU must be relatively powerful to allow execution to allow rapid reconstruction of compressed contone and binary level image data. Higher clock speeds will also require three to ten times the clock speed, which does not require software recovery. As in the second mode, at least 256 kbytes of DRAMdll MoPEC devices are required. The third mode has the advantage that it is programmable for the type of restoration operation to be performed. However, the need for a more powerful processor that is clocked at high speed means that power consumption can be significantly higher than in the first two modes.

It will be appreciated that all of these modes to be selected in one MoPEC device require the worst case to be executed. So, for example, at least 256 kbytes of DRAM, high clock speeds, relatively powerful processors, and the ability to selectively bypass CDUs and LBDs must all be implemented in MoPEC. Of course, one or more modes may be omitted for any particular implementation, as correspondingly removing the limitations of the features required by the utility of that mode.

 In a preferred form, the MoPEC device does not know color space agnostic. Although a MoPEC device can accept contone data as CMYX or RGBX (where X is an optional fourth channel), it may also accept contone data in any print color space. In addition, MoPEC provides a mechanism for arbitrary mapping of input channels to output channels, including combining dots for ink optimization and generation of channels based on any number of other channels. . However, the inputs are typically CMYK for contone input and K for binary level input.

In a preferred form, the MoPEC device is also resolution agnostic. It only provides a mapping between the input resolution and the output resolution by a scale factor. While the expected output resolution for the preferred embodiment is 1600 dpi, MoPEC does not actually know the physical resolution of the printhead supplying the dot data.

software dot  produce( SOFTWARE DOT GENERATION )

While considering speed and power consumption favors hardware acceleration, it is also desirable that some, most, or all of the functions executed by the MoPEC integrated circuits be executed by a general purpose processor programmed with suitable software routines. While power consumption will typically be increased to achieve performance similar to general-purpose processors (due to the high overhead associated with general-purpose processors executing highly specialized tasks such as restoration and synthesis), this solution is easy. There is also the advantage of customization and upgrading. For example, if a new or updated JPEG standard is widely used, it is desirable to simply update the reconstruction algorithm executed by a general purpose processor. Decisions to move some or all of the functionality of MoPEC integrated circuits into software need to be made commercially based on an individual basis.

QA  chip( QA CHIPS )

The preferred form of the invention does not use a QA chip to authenticate the cartridge when the cartridge is inserted. However, in alternative embodiments, the print cartridge has a QA chip 82 that can be interrogated by the master QA chip 80 installed in the mobile terminal (see FIG. 6). In this context, the QA chip is designed to ensure the quality of the ink supply so that the printhead nozzles are not damaged during printing, and the quality of the software to ensure the printhead and its structures is not compromised.

There are several ways QA chips can be used with MoPEC. For example, each MoPEC may have an associated printer QA, which stores information of printer attributes such as maximum print speed. An ink cartridge for use with the system may also include an ink QA chip, which stores cartridge information such as the amount of ink remaining. The cartridge may also have a QA chip configured to act as a ROM (actually an EEPROM) that stores printhead-specific information, such as dead nozzle mapping and printhead characteristics. In MoPEC devices, the CPU can selectively load and execute program code from a QA chip that effectively acts as a serial EEPROM. Finally, in SoPEC devices, the CPU executes a logic QA chip (ie, a software QA chip).

In general, all QA chips in a system are physically identical, with only the contents of the flash memory distinguishing from each other.

Each MoPEC device has an LSS system bus that can communicate with QA devices for system certification and ink usage evaluation. Many QA devices can be communicated via a bus.

 Data passed between QA chips is authenticated by digital signature. In a preferred embodiment, HMAC-SHA1 authentication is used for data and RSA is used for program code, although other designs may be used instead.

The QA chip preferably comprises some or all of the possible protection mechanisms that make the QA chip relatively difficult to attack. Many of these characteristics relate to how secret information (in the form of bit patterns) is stored in nonvolatile memory of the QA chip (preferably flash memory). Other features address hard coded limitations in the way that software is loaded from flash memory. Other features deal with hardcoding schemes that can modify the data in certain registers; For example, registers containing data indicative of ink levels remaining in the reservoir can only be reduced.

Using any of a number of techniques can make it more difficult for potential hackers to extract key data (in the form of bit patterns) from nonvolatile memory. For example:

키(key)들은 QA 장치의 다중의 경우를 가로질러 메모리 내의 다른 장소들 에 저장된다(각 장치의 소프트웨어는 그 위치를 아는 상태에서 최적화된 다);

The keys are stored in different places in the memory across multiple cases of the QA device (the software of each device is optimized with its location known);

하나 이상의 키는 메모리 내의 하나의 키/역 키(inverse-key) 쌍으로서 저장된다; 그리고/또는

One or more keys are stored as one inverse-key pair in memory; And / or

제2 키는 제1 함수(function)의 결과에 어떤 함수를 적용하는 결과의 형 태로 비휘발성 메모리에 간접적으로 저장된다. 제1 함수는 제1 키(비휘 발성 메모리에 저장됨)에 적용되며 일방향 함수를 제2 키에 적용하는 결 과이다. 제1 키와 비휘발성 메모리 내의 제1 함수의 결과를 저장함으로 써, 제2 키는 간접적으로만 저장된다. 일방향 함수는 대체로 제1 함수 보다 더 암호학적으로 안전한 것으로 선택될 것이다.

The second key is indirectly stored in the nonvolatile memory in the form of a result of applying a function to the result of the first function. The first function is applied to the first key (stored in nonvolatile memory) and the result of applying the one-way function to the second key. By storing the results of the first function in the first key and non-volatile memory, the second key is only stored indirectly. The one-way function will generally be chosen to be more cryptographically secure than the first function.

There may be limitations on the way in which communications are handled and handled. For example,

카트리지의 QA 칩과 이동단말기의 QA 칩 사이의 통신은 디지털 서명을 사 용(바람직하게는, 본 양수인에 의해 상호참조되는 여러 출원과 특허에서 설명한 바와 같이 변형 키(variant key)를 사용)하여 비교적 안전하게 이 루어질 수 있다; 그리고/또는

The communication between the QA chip in the cartridge and the QA chip in the mobile terminal is relatively simple using digital signatures (preferably using variant keys as described in the various applications and patents cross-referenced by the assignee). Can be done safely; And / or

QA 칩들 사이의 서명된 메세지는 페이로드(payload)의 일부로서, 그 페이 로드의 명령 타입의 표시를 포함할 수 있다.

The signed message between the QA chips may be part of a payload and include an indication of the instruction type of that payload.

There are also physical mechanisms that protect each QA chip. For example, anti-tamper lines formed on certain layers of integrated circuits cause resetting of the integrated circuits and / or deletion of memory contents in the event of interference. This prevents attempts to scrape the coating layer of the semiconductor in order to access the memory contents using various scanning mechanisms.

Another feature is the use of relatively unique identifiers within the family of related QA chips. For example, each QA chip, or at least each chip used in a particular region of a product, stores its own identifier. The identifier is relatively unique, which is entirely unique (i.e. it always appears on one QA chip and never repeats on the other QA chip), or very unlikely, but is an attacker that learns the key of one integrated circuit. It means that it is not enough that an attacher can use it in compromise with another randomly selected integrated circuit.

All of these features are described in more detail in the assignee's patent application USSN 10 / 754,536 (document number PEA25US), filed January 12, 2004, the contents of which are incorporated herein by reference.

Piezoelectric Driving System PIEZOELECTRIC DRIVE SYSTEM )

19-22 illustrate a piezoelectric drive system 126 for driving a print medium through a printhead. As best shown in FIG. 21, the drive system 126 has a resonator 156 having a support end 158, a through hole 160, a cantilever 162, and a spring 164. ). The support 158 is attached to the spring 164 and then to the mounting point 166 of the cradle 124. A piezoelectric element 168 is disposed in the through hole 160 and extends across the hole to connect the support end 158 and the cantilever 162. The element 168 is positioned adjacent one end of the aperture so that, upon deformation, the cantilever 162 is deflected by its minute amount from its rest position.

The tip 170 of the cantilever 162 is in contact with the rim of the driving wheel 172 and is biased at an angle of about 50 degrees. The drive shaft 178 is coupled to the print medium passing through the printhead to drive the print medium (described below with reference to FIGS. 12 and 14).

A drive wire (not shown) is attached to the opposite side of the piezoelectric element 168 to enable the supply of drive signals. Spring, piezoelectric and cantilever assemblies are structures having a series of resonant frequencies. The drive signal excites the structure in one of the resonance modes of vibration to move the upper end of the cantilever 162 in such a way that the drive wheel 172 rotates. In short, when the piezoelectric element is expanded, the upper end 170 of the cantilever is pushed out in contact with the rim of the driving wheel more firmly. Since the figure and the upper end are relatively hard, the moving upper end is rotated slightly in the direction shown by the drive wheel. During stop of resonant oscillation, the upper end 170 is released from contact with the rim and retracted slightly back toward the starting position. The next vibration then presses the wheel by another small rotation by pressing the upper end 170 back to a slightly different point relative to the rim.

The vibration of the upper end 170 is repeated in rapid continuity and the drive wheel is moved in a series of small angular displacements. However, because the resonant frequency is high (around kHz), the wheel 172 has a constant angular velocity for all intents and purposes.

In the illustrated embodiment, the drive signal at about 85 kHz rotates the drive wheel in the counterclockwise direction (as shown in FIG. 21).

Although the amount of momentum per cycle is relatively small (a few micrometers), a high pulse feed rate means that a linear movement of up to 300 mm per second (ie the movement of the rim) can be achieved. Another vibration mode can be caused by increasing the drive signal frequency to 95 kHz, which causes the drive wheel to rotate in the reverse direction. However, the preferred embodiment does not take advantage of the reversibility of the piezoelectric driver.

The exact details of the operation of the piezoelectric actuator can be obtained from the manufacturer Elliptec AG of Dortmund, Germany.

Motor drive system ( MOTOR DRIVE SYSTEM )

23-27 illustrate other embodiments of the cradle 124 and print cartridge 148 having a DC motor drive system for feeding medium 226 through the printhead 202. The print cartridge and cradle of FIG. 23 uses a 6 mm diameter DC motor 242 with a super gear, while FIG. 24 shows a range of super gear drive systems and a DC motor of 8 mm diameter. will be. 26 and 27 also show 6 mm and 8 mm motors, respectively, but use a worm gear system to power the drive wheel 172. These embodiments illustrate that the motor and gear drive system provide a wide range of arrangements and gearing ratios to suit other devices, such as mobile phones, PDAs, and the like.

Referring to FIG. 23, the longitudinal axis of DC motor 242 is parallel to the longitudinal length of cartridge 148 and cradle 124. Spade terminals 244 extend from one end of the motor to connect to the battery power supply. At the other end of the motor 242 is a planetary gear box 246 having a 4: 1 reduction ratio. The output shaft of the gearbox is fixed to the drive gear 248. The drive gear is a super gear that is engaged with the intermediate gear 250 around the stub axle mounted on the cradle 124. Next, the intermediate gear 250 drives the drive roller super gear 252 which is mounted for fixed rotation with the elastomeric drive roller 172.

As described above in connection with the piezoelectric drive embodiment, the elastic drive roller 172 engages a rubber roller at the end of the drive shaft 178 to drive the medium 226 through the printhead.

In FIG. 24, the 8 mm diameter DC motor 254 is again powered by a magnetic encoder 256 that is parallel to the length of the cradle 124 but with 1 + 8 digital lines per revolution. This allows the print engine controller (PEC) to register the rotational speed, the rate of rotation of the motor 254. The PEC uses this to measure the position of the medium 226 relative to the printhead and adjust the operation of the nozzle accordingly.

The planetary gearbox 246 is connected to the output side of the motor 254. The drive gear 258 having 15 teeth is fixed to the output shaft of the gearbox 246. As a 6 mm diameter motor, the drive gear 258 drives the drive roller super gear 252 via the intermediate gear 250. Then, it drives the medium drive shaft 178 via the rubber roller 176 and the elastic drive roller 172.

The structure shown in FIG. 25 is the same as the structure shown in FIG. 24 except that the output shaft of the gearbox 246 has a drive gear 260 having 20 teeth. By changing the gear ratio, it is possible to change the printing speed (that is, the speed of the drive shaft 178). This in turn affects the torque of the drive shaft 178 and thus the force that the card 226 moves along the media feed path.

Print cartridges PRINT CARTRIDGE )

Print cartridge 148 is best shown in FIGS. 28 and 29 and takes the form of a long, nearly rectangular box. The cartridge is disposed around a modular housing 180 that includes three elongated slots 182, 184, 186 configured to support respective ink-bearing structures 188, 190, 192. Each ink support structure is typically a sponge-like material or laminated fibrous sheet. For example, such structures can be foam, fibers and perforated membrane laminates. The ink support structures 188, 190, 192 form a substantial void region for receiving ink and are configured to prevent ink from moving when the cartridge (or mobile terminal in which the cartridge is installed) is shaken or otherwise moved. It is. The amount of ink in each reservoir is not critical, but a typical volume for each color may have between 0.5 and 1.0 mL.

The porous material also has a capillary action that establishes negative pressure in the spray nozzles. During the period of inactivity, the ink is retained in the nozzle chambers by the surface tension of the ink miniscus forming across the nozzle. If the meniscus swells outward, it can 'pin' itself to the nozzle rim for retaining ink in the chamber. However, if the nozzle rim contains paper dust or other contaminants, the meniscus can be released from the figure and ink will leak out of the printhead through the nozzle.

To address this, many ink cartridges are designed such that the hydrostatic pressure of the ink in the chamber is less than atmospheric pressure. This causes the meniscus at the nozzles to be recessed or pulled inward. This removes some positive pressure in the chamber that blocks the meniscus from contacting the dust of the paper on the nozzle rim and leaks ink.

Housing lid 194 fits with the top of the print cartridge to define an ink reservoir in combination with ink slots 182, 184, and 186. The lid may be in the form of glue glued, ultrasonically welded, or sealed with the top edge of the ink slot to prevent ink from moving between reservoirs or exiting the print cartridge. Ink holes 174 allow the reservoir to be filled with ink during fabrication. Microchannel vent 140 defines a tortuous path along lid 196 between ink hole 174 and breather hole 154. This outlet allows for pressure equalization in the reservoirs when the cartridge 148 is in use and allows the meandering path to prevent ink leakage when the mobile phone 100 is moved along different orientations. A label 196 covers the opening 140 and a tear-off portion that is removed prior to use to expose the air holes 154 to expose the slots 182, 184, 186 to the atmosphere. 198).

A series of outlets (not shown) at the bottom of each of the slots 182, 184, 186 leads to ink ducts 262 formed in the housing 180. The ducts are covered by a flexible sealing film 264 that directs ink to the printhead IC 202. One edge of the printhead IC 202 is bonded to a conductor on the flexible TAB film 200. This joint is covered and protected by an encapsulant strip 204. A contact 266 is formed on the TAB film 200 so that power and data can be supplied to the printhead IC 202 via conductors on the TAB film. The printhead IC 202 is mounted downstream of the housing 180 by a polymer sealing film 264. The film is perforated with a laser to allow ink in the duct 262 to flow into the printhead IC 202. The sealing and ink delivery form of the film is as described in more detail below.

A capper 206 is attached to the chassis 180 by a slot 208 that mates with a corresponding modularized pin 210 on the housing. In its capping position, the capper 206 surrounds and protects the exposed ink in the nozzles (described below) of the printhead 202. A pair of co-moulded elastomeric seals 240 on either side of the printhead IC 202 reduce their exposure to dust and air that can cause the nozzles to dry and clog. Let's do it.

The metal cover 224 is fastened in place during assembly to cover and retain the capper 206 in place. The metal cover is substantially U-shaped in cross section and includes an inlet slot 214 and an outlet slot 152 to allow the media to enter and exit the print cartridge. Tongue 216 at either end of metal cover 224 engages aperture 218 that engages complementary modular pawl 220 of lid 194. Include. A pair of capper leaf springs 238 are pressed from the bottom of the U-shape to bias the capper 206 to one side against the printhead 202. The tamper resistant label 222 is adapted to prevent inadvertent interference with the print cartridge 148.

As discussed above, the media drive shaft 178 extends across the width of the housing 180 and is supported to rotate by a corresponding hole 226 in the housing. An elastic drive wheel 176 is mounted at one end of the drive shaft 178 to engage the linear drive mechanism 126 when the print cartridge 148 is inserted into the mobile communication terminal before use.

Replacement print cartridge ( ALTERNATIVE PRINT CARTRIDGES )

Replacement cartridge 290 is shown in FIGS. 30-36. This cartridge design shares many features with those shown in FIGS. 28 and 29 and the corresponding components are denoted by the same reference numerals.

The fundamental difference of the replacement cartridge is that the negative pressure in the reservoir 288 (see Figure 33) is provided by biasing the flexible film to one side to increase the ink storage volume. As described above, negative pressure is necessary to block ink leakage from the nozzles. As best shown in FIGS. 31 and 32, the negative pressure reservoirs 288 are arranged in series across the print width of the cartridge 290. Preformed membrane 294 is attached to a corresponding formation 294 of housing 180 to define three reservoirs 288. The membrane 292 includes openings 296 in communication with each reservoir, each opening 296 having a closed cell neoprene or self-sealing silicone stopper 298. Is fitted. To fill the reservoirs, a hollow needle (not shown) penetrates the stopper 298 to inject ink. When the needle is removed, the stopper 298 seals the reservoir back. It is desirable to introduce two needles for refill, one of which is used to allow air to escape from the reservoir when the air is replaced with ink.

34, 35 and 36, each stopper 298 is a cap formation seated in a corresponding reservoir 288 to engage a spring 302 extending across the print width of the cartridge. 300. In the illustrated embodiment, the spring 302 has a collar 304 spaced along its length to engage each structure 300 and an angle of each opening 304 to provide elasticity. A serpentine portion 306 on the side. At each end of the spring 302, a portion is bent to form a short protrusion 308 that engages with a complementary notch 310 formed in the housing 180.

Lid 194 surrounds membrane 292 and includes a spring support 312 to position and support the corresponding portion of spring 302. The opening 314 of the lid exposes the cap structure 300 to fill.

The ink distribution system differs from the replacement cartridge because the reservoirs 288 are installed in different ways with respect to the print width. In particular, the replacement cartridge includes two ink distribution layers that distribute ink from each reservoir along each print width of the cartridge to each row of print nozzles. As best shown in FIG. 35, each reservoir has two ink outlets 316. The ink outlet 316 transfers ink to the ink distribution channel 324 at the bottom of the housing 180. There are three channels 324, each containing cyan, magneta and yellow inks, respectively. Each channel 324 extends along the length of the printhead IC 202 because different colors in each reservoir 288 need to be transmitted across the entire print width. The distribution channel 324 is covered by an ink duct film layer 318. This layer 318 has holes in its top surface to connect with a series of ducts 320 on its bottom surface. The ducts 320 are sealed by a sealing film 264. The laser-punched holes 322 pass through the sealing film to guide ink from the duct to the opposite side of the printhead IC 202.

Another cartridge design is shown in FIGS. 37-39. This cartridge is very similar to that shown in Figures 28 and 29, but the main difference is in the ink retaining structures 188, 190, 192. Ink-retaining structures are compressed foam divided into sections by partial cuts 368, the majority of which extends in the thickness of the structures. Ink baffles 366 are suspended from the downstream side of cartridge lid 194 and at partial cutouts 368 to provide a rigid barrier between adjacent areas of ink holding structures 188, 190, 192. Is fitted.

The baffles 366 counteract ink stuck to one end of the cartridge when the cartridge is accidentally supported in a substantially vertical orientation for an extended period of time. If the ink is stuck in one end of the cartridge, the other end can run out of ink early in use. Although there is still some communication between adjacent zones (cross sections below each partial cutout 368), the capillary action of the porous structures and the relatively small area of the communication delay the ink discharged to the lower end. Let's do it. The rate at which the ink is discharged to the bottom is slow enough to keep the ink in all areas of the ink holding structure when the cartridge is in an upright orientation overnight.

Adjacent zones that are completely sealed to each other reduce the amount of ink used before requiring replacement of the cartridge. Without any flow of ink between adjacent zones, one color will be depleted from one of the zone increments before the other. This is because the use of ink along the length of the printhead IC 202 is rarely uniform. In order to help the ink flow from the nozzles supplied by the depleted zones from one zone, a wick 364 at the bottom of each slot 182m 184m 186 is provided with an ink outlet (shown in the housing 180). Ink). These outlets communicate with a series of ink delivery ducts formed downstream of the housing 180. As best shown in FIG. 39, the ink delivery ducts 262 direct ink to the central ink delivery portion 370, which can supply ink to the back of the printhead IC 202. Between each ink delivery duct 262 are ink balance ducts 372. The balance ducts 372 are placed in each ink outlet that is in fluid communication with the adjacent ink outlets. The ducts 262 and 372 must be compact enough to retain ink at all times, regardless of whether the cartridge is in a vertical orientation.

The ducts 262, 372 are sealed by a flexible sealing film 264 attached downstream of the housing 180. The printhead IC 202 is attached to the other side of the sealing film 264. The printhead IC 202 has ink inlets for its nozzles (described below) on the opposite side (side attached to the film 264). The printhead IC 202 is attached to the membrane 264 such that its inlets match the array of laser perforated holes in the membrane. Laser-punched holes connect the printhead IC 202 to an ink inlet having ink delivery points spaced along the ink delivery zone 370 of the housing 180. The sealing and ink delivery aspects of the film are as described in more detail below.

One edge of the printhead IC 202 is bonded to a conductor on the flexible TAB film 200. The bond is covered and protected by a sealing strip 204. Contacts 266 are formed on the TAB film 200 to supply power to the printhead IC 202 via a power / ground contact 382 (see power / data connector 330 in another cartridge). do.

Printhead  Mechanical structure ( PRINTHEAD MECHANICAL )

In a preferred form, the Memjet printer includes a monolithic pagewidth printhead. The printhead is a three-color 1600dpi monolithic chip with an active print length of 2.165 "(55.0mm). The printhead chip is about 800 microns wide and about 200 microns thick.

Power and ground are supplied to the printhead chip via two copper busbars approximately 200 microns thick, which are electrically connected to the contacts along the chip with the conductive adhesive. One end of the chip has several data pads that are wire bonded or ball bonded to a small flexible PCB and then sealed, as described in greater detail elsewhere.

In alternative embodiments, the printhead is a bilithic based on SoPEC described in USSN 10/754536 (Document No. PEA25US), filed Jan. 12, 2004, incorporated herein by cross-reference. As described in connection with the printhead structure, it can be constructed using two or more printhead chips. In yet other embodiments, the printhead is a linked printhead module as described in USSN 10/754536 (Document No. PEA25US), filed Jan. 12, 2004, incorporated herein by cross-reference. It may be formed of one or more monolithic printhead comprising a.

In a preferred form, the printhead is designed to somehow at least partially self-destruct to prevent it from being refilled without being certified with ink that may be of questionable quality. Such self-destruction can be performed in any suitable manner, but the preferred mechanism is at least one fusible link in the printhead that is selectively blown when it is determined that ink is consumed or a predetermined number of prints are performed. It will include.

Alternatively or additionally, the printhead may be designed to at least partially reuse some or all of its components as part of a remanufacturing process.

Fuseable links on printhead integrated circuits (or separate integrated circuits in cartridges) may also be used to store other information that manufacturers would prefer not to change by the end user. A preferred example of such information is ink remaning data. By tracking the ink usage and selectively cutting the fuseable link, the cartridge can maintain an immutable record of the ink usage. For example, each time it is determined that 10% more of the total remaining ink has been used, ten fuseable links may be provided in a state of cutting one of the fuseable links. One set of links may be provided for each ink or for the entire ink. Alternatively or additionally, the fuseable link can be cut according to the desired number of prints performed.

Fuseable links may also be provided within the cartridge, and optionally cut during or after manufacture of the cartridge to encode an identifier (an identifier that is unique, relatively unique or not) within the cartridge.

Fuseable links may be associated with one or more shift registers in the same manner as loading data for printing. In fact, the required shift register elements may form part of register elements of the same chain that are loaded with dot data for printing. As such, the MoPEC chip can simply control the cutting of the fuseable link by changing the data inserted into the stream of data loaded during printing. Alternatively or additionally, data for cutting one or more fuseable links may be loaded during a separate operation with dot data loading (ie, the dot data is loaded as all zeros). Another alternative is to have its own shift register that the fuseable link loads regardless of the dot data shift register.

40 and 41 show a basic circuit diagram of ten fuse links and a single fuse cell, respectively. 40 shows a shift register 373 that can be loaded with a value programmed into 1-bit fuse cells 375, 377, 379. Each shift register 381, 383, 385 is each connected to a 1-bit fuse cell to provide a program value to its corresponding cell. These fuses are programmed by setting a fuse program enable signal 387 to one. Fuse cells 391, 393, 395 are loaded into 10-bit registers 389. This value 389 is accessed by the printhead IC control logic, for example, to block printing when the fuse value is all one. Alternatively or additionally, the value 397 can be read in series by the MoPEC to see the status of the fuses 375, 377, 379 after the MoPEC is powered on.

Possible fuse cells 375 are shown in FIG. 41. Before being cut, the fuse element structure itself has an electrical resistance 405 that is substantially lower than the value of the pullup resistor 407. This pulls down node A, which is initially buffered to provide a fuse value output 391 that is zero. The fuse is blown when both the fuse programmable signal 387 and the fuse program value 399 are one. This causes the PFET 409, which connects node A to Vpos, to turn on, thereby causing a current to flow through the fuse element into the open circuit, i.e., causing the resistor 405 to be infinite. .

Of printhead  Sealing SEALING THE PRINTHEAD )

As briefly described above, the printhead IC 202 is mounted downstream of the housing 180 by a polymer sealing film 264 (see FIG. 29). The membrane may be a thermoplastic membrane such as PET or polysulphone film, or may be in the form of a thermoset membrane such as manufactured by AL technologies and Rogers Corporation. The polymer sealing film 264 is a laminate with an adhesive layer on both sides of the central film and laminated on the downstream side of the modular housing 180. The ink duct 262 (or in the case of a replacement cartridge, the membrane layer 318) is such that the printhead IC 202 is in fluid communication with the ink duct 262 and the ink holding structures 188, 190, 192. A plurality of holes (not shown) are punctured by the laser through the sealing film 264 to coincide with the ink delivery point in the ink duct 320.

The thickness of the polymer sealing film 71 is important for the effectiveness of the ink sealing that the film provides. The film seals ink ducts (not shown) on the opposite side of the printhead IC 202 as well as the ink ducts 262 (the ink ducts 320 of the film layer 318) on the housing 180. However, as the membrane 264 seals across the duct 262, it may sag into one of the conduits on the opposite side of the printhead IC 202. A portion of the film sagging into the conduit skips several ink ducts 262 in the printhead IC 202. This deflection may cause the gap to collapse, causing the ink to leak from the printhead IC 202 or between conduits on the opposite side.

In order to prevent this, the polymer sealing film 264 does not sag into the ink duct 262 (or the ink duct 320 of the film layer 318) while maintaining the sealing property of the back of the printhead IC9202. It needs to be thick enough to be considered. The minimum thickness of the polymer sealing film 264 will depend on the following.

막이 처지는 도관의 폭;

The width of the conduit in which the membrane sags;

막의 라미네이트 구조에서의 접착제층들의 두께;

For the illustrated printhead IC and cartridge assembly, a polymer sealing film 264 having a thickness of 25 microns is suitable. However, as the thickness increases to 50,100 or 200 microns, the reliability of the provided seal will increase accordingly.

Printhead  CMOS ( PRINTHEAD CMOS )

42 to 47, a preferred embodiment of the printhead 420 will be described.

42 shows an overview of the connection to the printhead IC 425 and the MoPEC device 166. The printhead IC 425 includes a nozzle core array 401 that includes repeated logic for spraying each nozzle and nozzle control logic for generating timing signals for spraying the nozzles. 402). The nozzle control logic 402 receives data from the MoPEC chip via a high speed link. In a preferred form, a single MoPEC chip 166 provides print data to two printhead ICs 425 and 426.

The nozzle control logic is configured to send serial data to the nozzle array core for printing via a link 407 that is an electrical connector to the printhead 425. Status and other operational information for the nozzle array core 401 is also communicated back to the nozzle control logic via another link 408 installed on the electrical connector.

The nozzle array core 401 is shown in more detail in FIGS. 43 and 44. In FIG. 43, it will be appreciated that the nozzle array core includes an array of nozzle columns 501. The arrangement includes a fire / select shift register 502 and three color channels, each of which is indicated by a corresponding dot shift register 503.

As shown in FIG. 44, the injection / select shift register 502 includes a forward path fire shift register 600, a reverse path injection shift register 601 and a select shift register 602. ). Each dot shift register 503 includes an odd dot shift register 603 and an even dot shift register 604. Odd and even dot shift registers 603 and 604 are connected at one end so that data can be clocked through odd shift register 603 in one direction and then even shift register 604 in the opposite direction. do. The outputs of all but the final even dot shift registers are fed to one input of a multiplexer 605. The input of this multiplexer is selected by the signal (corescan) during the post-production test. In normal operation, the corescan signal selects the dot data input Dot [x] provided to another input of the multiplexer 605. This causes a Dot [x] for each color to be provided to the respective dot shift registers 503.

One column N will now be described with reference to FIG. In the illustrated embodiment, column N consists of an odd data value held by element 606 of odd shift register 603 and an even data value held by element 607 of even shift register 604. Contains data values. Column N also includes an odd injection value 608 from forward injection shift register 600 and an even injection value 609 from reverse injection shift register 601, which is provided to multiplexer 610 as inputs. The output of the multiplexer 610 is controlled by the select value 611 in the select shift register 602. When the select value is 0, the odd injection value is output, and when the select value is 1, the even injection value is output.

Respective odd and even data values 606 and 607 are provided as inputs to corresponding odd and even dot latches 612 and 613, respectively.

Each dot latch 612, 613 and its associated data shift register elements form a unit cell 614, which is shown in more detail in FIG. 45. Dot latch 612 is a D-type flip-flop that accepts the output of shift register element 606. Data input d to shift register element 606 is provided from the output of the previous component in the odd dot shift register, provided that if the element under consideration is not the first element in the shift register, the input value is Dot. [x] value). Data is clocked from the output of flip-flop 606 to latch 612 upon receipt of a negative pulse provided to LsyncL .

The output of latch 612 is provided as one of the inputs to three input AND gates 65. The other inputs to AND gate 615 are the Fr signal (from the output of multiplexer 610) and the pulse profile signal Pr. The injection time of the nozzle is controlled by the pulse profile signal Pr and can be increased to take into account the low voltage state that arises, for example, due to the low battery (in battery operated embodiments). This ensures that a relatively constant amount of ink is ejected from each nozzle efficiently when ejected. In the described embodiment, the profile signal Pr is the same for each dot shift register providing a balance between complexity, cost and performance. However, in other embodiments, the Pr signal may be applied globally (i.e. the same for all nozzles), or may be individually tailored to each unit cell or to each nozzle as well.

Once the data is loaded into the latch 612, the spray enable Fr and pulse profile Pr signals are applied to the AND gate 615, which is one dot for each latch 612 that includes logic 1 to the nozzle. Connected to causing the ink to eject.

The signals for each nozzle channel are summarized in the following table.

As shown in Fig. 45, the firing signal Fr is routed diagonally to enable the spraying of one color in the current row, the color following in the next row, and so on. This averages the current demand by spreading across three nozzle rows in a time-delayed manner.

Dot latches and latches forming the various shift registers are completely static in this embodiment and are based on CMOS. The design and structure of the latches are well known to those skilled in the art of integrated circuit engineering and design and therefore will not be described in detail herein.

The combined printhead IC defines a printhead with 13824 nozzles per color. The circuit supporting each nozzle is the same, but the pairing of nozzles occurs due to the physical positioning of the MEMS nozzles; Odd and even nozzles are not actually on the same horizontal line, as shown in FIG. 46.

Nozzle Design-Mechanical Actuator NOZZLE DESIGN  - MECHANICAL ACTUATOR )

A preferred nozzle design (including nozzle and corresponding actuator) for use in the printhead chip 216 is described below with reference to FIGS. 21.1-46 to 21.1-55. 47 illustrates an arrangement of nozzles 801 formed on a silicon substrate 8015. All of the nozzles 810 in the printhead chip 216 are identical to each other, but are grouped together in rows, each row providing a particular ink color. The specific number / resolution of nozzles, the number of rows of nozzles, their position and offset relative to each other, and the specific combination of ink and fixative output by a particular cartridge may vary from one embodiment to another. You will see that you can.

In the illustrated embodiment, the rows of nozzles 801 can be staggered from one another to narrow the spacing of the ink dots than would be possible with a single row of nozzles during printing.

Each nozzle device 801 is a product of integrated circuit fabrication technology. In particular, the nozzle arrangement 801 defines a micro-electromechanical system (MEMS).

In order to make the description clear and easy, the configuration and operation of the single nozzle device 801 will be described with reference to FIGS. 48 to 57.

The inkjet printhead chip 12 includes a silicon wafer substrate 801. On the silicon wafer substrate 8015 is placed 0.35 micron 1 P4M 12 volt CMOS microprocessing electronics.

A silicon dioxide (or alternatively glass) layer 8017 is located on the substrate 8015. The silicon dioxide layer 8017 defines CMOS dielectric layers. CMOS top-level metal defines a pair of aligned aluminum electrode contact layers 8030 positioned on silicon dioxide layer 8017. Both silicon wafer substrate 8015 and silicon dioxide layer 8017 are etched to define ink inlet channel 8014 having a generally circular cross section (viewed from the top). Aluminum diffusion barrier 8028 of CMOS metal 1, CMOS metal 2/3 and CMOS top-level metal In the silicon dioxide layer 8017, it is located around the ink inlet channel 8014. The diffusion barrier 8028 prevents the diffusion of hydroxyl ions through the CMOS dioxide layers of the drive electrical device layer 8017.

A passivation layer in the form of a layer of silicon nitride 8031 is positioned over the aluminum contact layers 8030 and silicon dioxide layer 8017. Each portion of the passivation layer 8031 positioned over the contact layers 8030 has an opening 8302 formed therein to provide access to the contact 8030.

The nozzle apparatus 801 includes a nozzle chamber 8029 defined by an annular nozzle wall 8033, which is a radial inner nozzle rim 804 and a nozzle top that are circular in plan view. It ends at the upper end in 8034. The ink inlet channel 8014 is in fluid communication with the nozzle chamber 8029. At the lower end of the nozzle wall, there is a movable rim 8010 comprising a movable seal lip 8040. A circumferential wall 8038 surrounds the movable nozzle, which is When the nozzle is at rest as shown in Figure 26, it includes a stationary seal lip 8039 adjacent to the movable rim 8010. Fluid seal 8011 Is formed due to the surface tension of the ink trapped between the stationary seal lip 8039 and the movable seal lip 8040. This provides a low resistance coupling between the circumferential wall 8038 and the nozzle wall 8033. While preventing the ink leakage from the chamber.

As best shown in FIG. 57, a plurality of radially extending recesses 8035 are defined in a top 8034 around the nozzle rim 804. The recesses 8035 serve to include radial ink flow as a result of ink exiting past the nozzle rim 804.

The nozzle wall 8033 is of a lever arrangement mounted to a carrier 8036 having a generally X-shaped cross section with a base 8037 attached to a layer 8031 of silicon nitride. To form part.

The lever device also includes a lever arm 8018 extending from the nozzle wall and incorporating a lateral stiffening beam 8802. This lever arm 8018 is attached to a pair of passive beams 806 formed of titanium nitride (TiN) and positioned on the sides of each nozzle, as best shown in FIGS. 50 and 51. . The other end of the passive beams 806 is attached to the carrier 8036.

The lever arm 8018 is also attached to an actuator beam 807 formed of TiN. This attachment to the actuator beam is, at some point, made smaller but with a higher critical distance than attachments to the passive beam 806.

As best shown in Figs. 51 and 56, this actuator beam 807 is substantially planar in plan view and defines a current path between the electrode 809 and the counter electrode 8301. . Respective electrodes 809 and 8041 are electrically connected to respective points of the contact layer 8030. In addition to being electrically connected via the contacts 809, the actuator beam 173 is mechanically fixed to the anchor 808. The anchor 808 is shown in FIGS. 21.1-52 when the nozzle arrangement is in operation. It is formed so that the movement of the actuator beam 807 toward the left side of FIG. 54 can be suppressed.

TiN of the actuator beam 807 is conductive, but has a sufficiently high electrical resistance to cause self-heating when current flows between the electrodes 809 and 8041. Since no current flows through the passive beams 806, these passive beams do not expand.

In use, the nozzle is filled with ink 8013 that defines a meniscus 803 under the influence of surface tension. This ink is held in the chamber 8029 by the meniscus and generally does not leak unless there is another physical effect.

As shown in FIG. 50, to eject ink from the nozzle, a current passing through the actuator beam 807 is passed between the contacts 809 and 8041. Self heating of the beam 807 causes the beam to expand due to its resistance. The dimensions and design of the actuator beam 807 means that the majority of expansion is in the horizontal direction with respect to FIGS. 50-53. The inflation is limited to be left by the anchor 808 and the end of the actuator beam 807 adjacent to the lever arm 8018 is pushed out to the right.

The relative horizontal inflexibility of these passive beams 806 prevents the passive beams from allowing more horizontal movement of the lever arm 8018. However, the relative displacement of the attachment points of the respective actuator beams and the actuator beams to the lever arms is generally lowered by the lever arm 8018 by pivoting or hinging motion. It results in a twisting movement, causing it to move. However, the lack of an accurate pivot point means that the rotation takes place around the pivot region defined by the bending of the passive beams 806.

The downward movement (and some rotation) of the lever arm 8018 is amplified by the distance from the passive beams 806 to the nozzle wall 8033. Downward movement of the nozzle walls and top results in an increase in pressure in the chamber 8029 causing expansion of the meniscus as shown in FIG. 49. Note that the surface tension of the ink means that the fluid seal 8011 is stretched by this movement without allowing the ink to leak.

Immediately after the ink droplets 802 are separated, the meniscus forms a concave shape shown in FIG. Due to the surface tension, the pressure in the chamber 8029 continues to be relatively low until the ink is sucked up through the inlet 8014, which returns the nozzle arrangement and the ink to the stationary state shown in FIG.

As best shown in FIG. 52, the nozzle apparatus also incorporates a test instrument that can be used both after prefabrication and after installation of the printhead. The test instrument includes a pair of contacts 8020 that are connected to a test circuit (not shown). Bridging contacts 8019 are provided over the projections 8043 extending from the lever arm 8018. Since the bridging contact 8019 is on the opposite side of the passive beam 806, the operation of the nozzle causes the priding contact to move upwards in contact with the contact 8020. The test circuit can be used to confirm that the operation causes the closure of the circuit formed by the contacts 8019, 8020. If the circuit is properly closed, it can generally be assumed that the nozzle is in operation.

The design of the nozzle- Thermal  Actuator { NOZZLE DESIGN  - THERMAL ACTUATOR )

The design of the replacement nozzles utilizes a thermal inkjet mechanism to eject ink from each nozzle. The thermal nozzles are arranged like their mechanical equivalents, although necessary to account for other pulse profiles due to any difference in drive characteristics, if necessary, and to similar control signals by similar CMOS circuitry. Supplied by us.

58 through 62, a nozzle of a printhead according to an embodiment of the present invention consists of a nozzle plate 902 having nozzles 903 therein, the nozzles extending through a nozzle plate. rim 904 and opening 905. The nozzle plate 902 is plasma etched from a silicon nitride structure deposited by chemical vapor deposition (CVD) on a sacrificial material that is subsequently etched.

The printhead further includes sidewalls 906 on which nozzle plates are supported for each nozzle 903, chambers 907 formed by the sidewalls and nozzle plates 902, multilayered structures 908, and An inlet passage 909 extends through the multilayer structure to a far side (not shown) of the substrate. A long heater member 910 of a loop type is suspended in the chamber 907, and the heater member is in the form of a suspended beam. The printhead as shown is a microelectromechanical system (MEMS) structure and is formed by a lithographic process described in more detail below.

When the printhead is in use, ink 911 from a reservoir (not shown) enters the chamber 907 via the inlet passage 909, so that the chamber is at a level as shown in FIG. Is filled. Thereafter, the heater member 910 is heated for some time for less than 1 microsecond, so that the heating is in the form of a thermal pulse. Since the heater member 910 is in thermal contact with the ink 911 in the chamber 907, it can be seen that when the heater member is heated, this causes the generation of vapor bubbles 912 in the ink. There will be. Thus, the ink 911 constitutes a bubble forming liquid. FIG. 58 illustrates the formation of bubble 912 for approximately one microsecond after generation of a heat pulse, ie, when the bubble nucleates the heater member 910. As the heat is applied in the form of a pulse, it will be appreciated that all the energy needed to generate the bubbles 12 must be supplied in a short time.

In operation, a voltage is applied across the electrodes (not shown) so that a current flows through the member 910. The electrodes 915 are much thicker than the member 910 so that most of the electrical resistance is provided by the member. Thus, almost all of the power consumed in operating the heater 914 is depleted via the member 910 causing the heat pulses mentioned above.

When the member 910 is heated as described above, a bubble 912 is formed along the length of the member, which bubble appears as four bubble portions in the cross-sectional view of FIG. 58, one for each member portion. Is shown in the cross section.

Once generated, the bubble 912 increases the pressure in the chamber 97 and in turn ejects a drop 916 of ink 911 through the nozzle 903. The rim 904 assists the direction of the droplet 916 as the ink droplet is ejected, minimizing the risk of the droplet pointing in the wrong direction.

The reason there is only one nozzle 903 and chamber 907 per inlet passage 909 is that pressure waves generated within the chamber during heating of the member 910 and formation of air bubbles 912 are associated with the adjacent chambers and their chambers. This is to avoid affecting the corresponding nozzles.

Hereinafter, the advantages of the heater member 910 suspended rather than embedded in any solid material will be described.

59 and 60 show the unit cell 901 in two successive subsequent stages of operation of the printhead. It can be seen that the bubble 912 is further generated, thereby growing in the synthetic advancement of the ink 911 through the nozzle 903. As shown in FIG. 60, as the ink is grown, the shape of the bubble 912 is determined by a combination of the surface tension of the ink 911 and the inertia dynamics. Since the surface tension tends to minimize the surface area of the bubble 912, the bubble essentially has a disk shape until a predetermined amount of liquid is evaporated.

The increase in pressure in the chamber 907 not only pushes the ink 911 out through the nozzle 903, but also pushes some of the ink back through the inlet passage 909. However, the inlet passage 909 is approximately 200-300 microns in length and only approximately 16 microns in diameter. Therefore, there is a substantial viscous drag. As a result, the significant effect of the pressure rise in the chamber 907 is that ink is forced out through the nozzle 903 as sprayed droplets 916 rather than flowing back through the inlet passage 909. will be.

Returning now to FIG. 61, the printhead is shown in another successive stage of operation, where the ink droplets 916 ejected are shown during their "necking phase" before being destroyed. At this stage, the bubble 912 had reached its maximum size in advance and then began to collapse towards the collapse point 917 as shown in more detail in FIG. 5.

By the collapse of the bubble 912 toward the collapse point 917, a portion of the ink 911 is attracted from within the nozzle 903 (from the sides 918 of the drop), and a portion of the ink 911 is pulled out. To be drawn out from the inlet passage 909 toward. Most of the ink 911 drawn in this manner is drawn from the nozzle 903 and pulls the annular neck 919 at the base of the droplet 916 prior to its destruction. Form.

The droplet 916 requires a predetermined amount of driving force in order to overcome the surface tension and be destroyed. Since ink 911 is drawn from the nozzle 903 by the collapse of the bubble 912, the diameter of the neck portion 919 is reduced, thereby reducing the total amount of surface tension holding the drop. . Thus, as the droplet is ejected out of the nozzle, the propulsion of the droplet is sufficient to destroy the droplet.

When the droplet 916 is destroyed, the cavitation force is generated as indicated by the arrow '920' as the bubble 912 collapses to the collapse point 917. Note that there is no hard surface in the vicinity of the collapse point 917 where the cavitation can take effect.

Cradle CRADLE )

Since the moving device itself cannot say that the ink supply system is in use, the various cartridges described above are used in the same manner. Therefore, the cradle will be described with reference to only the cartridge 148.

Referring to FIG. 63, cartridge 148 is axially inserted into mobile phone 100 in engagement with cradle 124 via access cover 282. As shown previously in FIGS. 19 and 21, cradle 124 is a long U-shaped molding that defines a channel dimensioned to closely correspond with the dimensions of print cartridge 148. Referring now to FIG. 64, the cartridge 148 slides along the rail 328 upon insertion into the mobile phone 100. The edge of the lid molding 194 fits under the rail 328 for positional tolerance control. As shown in FIGS. 19-21, the contacts 266 on the cartridge TAB film 200 are pushed against the data / power connector 330 in the cradle. The other side of the data / power connector 330 contacts the cradle flexible PCB 332. The PCB connects the cartridge and the MoPEC chip to the mobile phone's power source and host electronics (not shown), providing power and dot data to the printhead for printing. The interaction between the MoPEC chip of the mobile communication terminal and the host electronic circuit is described in the above mentioned netpage and mobile terminal overview.

Media Feed ( MEDIA FEED )

12 to 14 illustrate a medium fed through a mobile communication terminal and printed by a printhead. 12 shows a blank medium 226 when the card is fed to the left side of the mobile phone 100. FIG. 13 is a cross-sectional view taken along the line A-A of FIG. 12. FIG. 13 shows a card 226 entering the media feed path guided through the card insertion slot 228 to the print cartridge 148 and the print cradle 124. The rear cover molding 106 has guide ribs that narrow the width of the media feed path toward the duct slightly thicker than the card 226. In FIG. 13, card 226 has not yet entered print cartridge 148 through slot 214 in metal cover 224. The metal cover 224 has a series of spring fingers 230 (described in more detail below) formed along one edge of the inlet slot 214. These protrusions 230 are biased to one side with respect to the drive shaft 178 so that when the card 226 enters the slot 214 as shown in FIG. 14, the protrusion guides the card to the drive shaft 178. The nip between the drive shaft 178 and the protrusion 230 engages with the card 226 and is quickly pulled between them. The protrusion 230 presses the card 226 against the drive shaft 178 to drive the card 226 through the printhead 202 by friction. The drive shaft 178 has a rubber coating to improve its grip on the medium 226. Media feeding during printing will be described later.

It is desirable to select the drive mechanism to print the print medium in about 2 to 4 seconds. Faster speeds require relatively higher drive currents and limit peak battery output, while slower speeds are unacceptable to consumers. However, it can certainly provide fast and slow speeds for commercial demands.

Capping Removal ( DECAPPING )

Decapping of the printhead 202 is shown in FIGS. 65-74. 65 shows the print cartridge 148 immediately before feeding the card 226 to the inlet slot 214. The capper 206 is biased to one side to the capping position by the capper leaf spring 238. The capper's elastomeric seal 240 protects the printhead from paper dust and other contaminants while preventing the ink in the nozzles from drying out when the printhead is not in use.

65 and 68, the card 226 is supplied to the print cartridge 148 via the inlet slot 214. The spring protrusion 230 pushes the card against the drive shaft 178 when the card is driven through the printhead. Directly downstream of the drive shaft 178, the leading edge of the card 226 engages with the inclined front face of the capper 206 to bring the card into the non-capping position against bias toward one of the capper leaf springs 238. Push out. Since the capper 206 rotates about a pin 210 seated in its slot 208 (see FIG. 29) by the linear movement of the card, the movement of the capper is initially a rotary motion. However, as shown in FIGS. 69-71, the capper may be mounted on the capper so that further movement of the card is directed below and away from the printhead 202, as opposed to the biasing action of the spring 238. It is constrained to start causing linear movement directly. Ink jetting from the printhead IC 202 onto the card begins when the leading edge of the card reaches the printhead.

As best shown in FIG. 71, the card 226 continues along the media path until it is engaged with the capper lock actuating arms 232. This is to operate the capper lock to support the capper in the non-capping position until printing is completed.

Capping CAPPING )

72 to 74, the capper is in the non-capping position until the card 226 is released from the actuating arm 232. In this regard, the capper 206 is released and returned to the capping position by the leaf spring 230.

Capper Locking  And unlocking { CAPPER LOCKING AND UNLOCKING )

75-79, the card 226 slides in contact with the elastic seal 240 when driven through the printhead 202. Subsequently, the leading edge of the card 226 engages with the pair of capper locking mechanisms 212 on either side of the media feed path. The capper locking mechanism 212 is rotated by the card 226 until the latch surface engages the lock engagement surface 236 of the capper 206 until the card is removed from the print cartridge 148. It is supported at the non-capping position.

75 and 78 show the locking mechanism 212 and the capper 206 in the capping position in the unlocked state. The actuating arms 232 of each caplocking mechanism 212 protrude toward the media path. Sides of the capper 206 prevent the actuating arms from rotating out of the media feed path. 76, 77A, 77B and 79, the leading edge of the card 226 engages with the arms 232 of the capperlocking mechanism 212 protruding from either side toward the media path. When the leading edge reached the actuating arms 232, the card 226 was previously pushed out of the capper 206 to the non-capping position so that the locking mechanism 212 is now free from rotation. As the card is pushed through the arms 232, the locking mechanism 212 has an angled lock with its respective chamfered latch surface 234 on either side of the capper 206. Slidably engages with the engaging surface (238). Sliding engagement between these faces pushes the capper 206 removed from the card 226 so that it no longer contacts the elastic seal 240. This reduces drag that delays media feeding. Sides of the card 226 sliding against the actuating arms 232 prevent rotation of the locking mechanism 21 so that the capper 206 is pushed by the latch surface 234 pressed against the lock engagement surface 238. Locked at the capping position.

Once the printed card 226 is retrieved by the user (described in more detail below), the operating arm 232 is released and free from rotation. The capper leaf spring 238 returns the capper 206 to the capping position, and in doing so, the latch surface 234 contacts and slides on the lock engagement surface 236 so that the actuating arm 232 feeds the media feed path. Retract toward and rotate

Alternative capping mechanism ALTERNATIVE CAPPING MECHANISM )

Alternative capping mechanisms are shown in FIGS. 81-84, which show an initial retraction of the capper away from the printhead before the card is tightened between the roller and the spring projection. In this embodiment, the cartridge includes a crankshaft 272 mounted parallel to the drive shaft. The crankshaft is connected to the first crank 274 and the second crank 276, which are spaced apart from each other at an angle.

When the card is inserted by the user into the cartridge, its leading edge comes into contact with the first crank 274. Pushing the card further into the cartridge, the first crank 274 converts the linear motion of the card into rotation of the crankshaft 272. Next, the second crank 276 thus pulls the capper 206 exactly apart from the printhead chip, as shown in FIGS. 81-84. By the time the card is tightened between the drive shaft 178 and the spring protrusion 230, the capper 206 is retracted away from the printhead chip in advance to allow the card to be completely free to move through the printhead. Preferably, the locking mechanism described in connection with the above capping mechanism is incorporated to ensure that the capper remains in the retracted state until the card removes the printhead chip.

It will be appreciated that the crankshaft 272 may be further positioned along the card feed path to the point where some or all of the rotation of the crankshaft occurs as a result of the drive shaft driving the card. However, this results in lengthening the entire feeding path and further moving the drive shaft from the exit slot, which is not a desirable option.

For marking  Cartridge with pen tip ( CARTRIDGE WITH MARKING NIB )

85-87 show a variant of the cartridge / cradle assembly with marking nibs 384 extending from one end of cartridge 148 and the netpage optics module 350 is cradle 124. Is integrated into. As best shown in FIG. 87, the marking nib 384 has a ballpoint pen with a coarse screw thread 388 for engaging an internal thread of a twist knob 382. (ball point pen). The twist knob is supported by a tubular detail 386 on the cartridge lid 194 by snapping an end flange. By rotating the twist knob 382, the nib 384 for use as a pen can be made to come out or enter, thereby avoiding the inadvertent use of the marking lid.

In this embodiment, the switch is simply omitted and the device operates continuously. To reduce power consumption, only the optical module 350 and the IR LED 344 operate when placed in capture mode. Alternatively, the switch may take the form of a pressure sensor such as a piezoelectric or semiconductor based transducer. In one form, a multi-level or continuous pressure sensor can be used, which makes it possible to capture the actual force of the nib against the writing surface during writing. This information may be included along with the location information and ID including the digital ink generated by the device. However, this is an optional capability.

Optical print data transmission OPTICAL PRINT DATA TRANSMISSION )

In the present embodiment, as shown in Figs. 88 to 90, print data from the MoPEC chip 326 is printed by the TAB film 200 when the printhead IC 202 is in another cartridge design. It is not sent to the head IC. Instead, the data is sent to the data LED 376 via a separate flexible film 374. As best shown in FIGS. 89 and 90, the printhead IC 202 is extended to receive an optical sensor 380 for receiving a data signal from the data LED 376. An opening 378 is formed in the metal cover 224 so that the data LED 376 can illuminate the light sensor 380. Transferring print data separately from the power source eliminates significant noise from the data signal. Back EMF from the multiple and frequent operation of each nozzle generates high frequency noise that can partially obscure the data signal. Also, the characteristics of the print data signal are well suited for optical transmission.

Print media and print PRINT MEDIA AND PRINTING )

The netpage printer normally prints tags that arrange surface coding at the same time, ie, when printing graphic page content. Alternatively, in a netpage printer that cannot print tags as in the preferred embodiment, it is possible to use pre-tag but blank netpages otherwise. Instead of being able to print tags, the printer typically incorporates a netpage tag sensor. The printer detects the area ID of the blank either before, during or after printing the graphic page contents on the tags and thus the empty netpage. The printer communicates the area ID to the netpage server, which associates the page content with the area ID in a conventional manner.

Certain netpage surface coding schemes assign the least bits to the representation of spatial coordinates within the surface area. If a particular medium size is significantly smaller than the maximum size that can be represented by the minimum number of bits, the netpage code space may be used inefficiently. Thus, it may be of interest to assign different subareas of a region to the collection of blanks. Although this constitutes the association maintained by the more complex netpage server, and the subsequent routing of more complex interactions, it leads to more efficient code space usage. In the limited case, surface coding may use a single region with a single coordinate space, ie without an explicit region ID.

Once the regions are subdivided, the netpage printer uses its tag sensor to determine not only the region ID but also the surface coding point of the known physical location on the print medium, ie with respect to the two edges of the medium. From the surface coding point and its corresponding physical location on the print medium and the known (or determined) size of the print medium, the spatial extent of the medium in the coordinate space of the area is determined to determine both the area ID and the space range. Communicate to the server The server associates the page content with a specified subarea of that area.

Multiple mechanisms can be used to read tag data from the blank. To capture an image of the tagged surface of the blank at any convenient point in the paper path of the printer, a conventional netpage tag sensor that incorporates a two-dimensional image sensor can be used. Alternatively, a linear image sensor can be used to capture a continuous line image of the tagged surface of the blank during transfer. Line images can be used to produce two-dimensional images that are processed in a conventional manner. As another alternative, region ID and other salient data may be linearly encoded on the blank, and a simple photodetector and ADC may be used to obtain linearly encoded samples during transport.

One important advantage of using a two-dimensional image sensor is that tag detection can occur before the power transfer of the print media begins, ie if the print media is manually inserted by the user, tag detection will occur during the insertion. Can be. This has the further advantage that once the tag data is verified by the device, the print medium can be rejected and possibly ejected before printing starts. For example, the print media is pre-printed with advertising or other graphical content on the opposite side from the intended print side. The device may use tag data to detect incorrect media insertion, i.e. when the top and bottom are reversed, or when the front and back are reversed. The apparatus can also prevent accidental overprinting of preprinted media. The device may then reject printing by detecting an attempt to use an inappropriate print media, for example, to protect print quality. The apparatus can also derive print media characteristics from tag data in order to be able to perform optimal print preparation.

If a linear image sensor is used, or if a photodetector is used, image sensing should occur during power transfer of the print medium to ensure accurate imaging. If there are at least two contact points between the print medium and the transfer mechanism in the print path separated by the minimum distance such as the tag data acquisition distance, the tag data cannot be extracted before printing starts and the above-mentioned effective advantages are not obtained. In the case of a linear image sensor, the tag data acquisition distance is equal to the diameter of a typical tag that images the field of view. In the case of the photodetector, the tag data acquisition distance is as long as the required linear encoding process.

If the tag sensor can operate during the entire printing stage at a sufficiently high sampling rate, the tag sensor can be used to perform accurate motion sensing, providing a line sync signal to the print engine. Motion data is used here. This can be used to eliminate the effects of jitter on the feed mechanism.

91 through 97 illustrate one embodiment of a coded medium and a medium sensing and printing system in a mobile communication terminal. Although the encoding of the card has been briefly described here, the encoding of the card is described in detail in the section of Coded Media herein. Similarly, optical detection of encoded data is described elsewhere in this specification, and for a comprehensive understanding of M-print media and printing systems, it is necessary to read this specification as a whole.

Referring to FIG. 91, one 'rear side' of card 226 is shown. The back side of the card has two coded data tracks, a 'clock track' 434 and a 'data track' 436 extending along the longitudinal side of the card. Cards are in particular encoded with data indicating the following:

카드의 방위(orientation);

Orientation of the card;

매체 유형 및 확실성(authenticity);

Media type and authenticity;

길이방향 크기;

Longitudinal size;

사전 인쇄(pre-print)된 측면;

Pre-printed sides;

카드 상의 사전 인쇄의 검출; 및

Detection of pre-printing on the card; And

프린트헤드 IC에 대한 카드의 위치

Card Position for the Printhead IC

In fact, the encoded data is printed in IR ink, so it does not break into the space useful for printing invisible and visible images.

In its basic form, M-print card 226 is only encoded with data tracks and clocking (separate clock tracks or self-clocked data tracks). However, in the more elaborate embodiment shown in the figure, the card 226 has a preprinted netpage tag pattern 438 that covers the majority of the back side. The front side may also have a preprinted tag pattern. In such embodiments, it is preferable that the data track encodes the first information representing at least the second information encoded in the tags. Most preferably, the first information simplifies the document identifier encoded in each tag.

The clock track 434 allows the MoPEC 326 (see FIG. 92) to determine by its presence that the front of the card 226 faces the printhead 202 and also allows the printer to print. It is possible to detect the operation of the card 226 during. Clock track 434 also provides a clock to densely coded data track 436.

The clock track 436 allows the MoPEC 326 to reject the unauthorized or unauthenticated medium 226 and also report the netpage identifier of the front side netpage tag pattern to the netpage server. Provide a netpage identifier and optionally associated digital signature (as described elsewhere herein).

FIG. 92 is a block diagram of an M-print system using media encoded with separate clock tracks and data tracks. Clock tracks and data tracks are read by separate optical encoders. The system can optionally have an explicit edge detector 474, which is described in more detail below with respect to FIG.

93 illustrates a simplified circuit of an optical encoder that can be used as a clock track or data track optical encoder. The optical encoder incorporates a Schmitt trigger 466 to provide the MoPEC 326 with an essentially binary signal representing the mark and space faced by the encoder on a clock or data track. . IR LED 472 is configured to illuminate the mark-sized area of card 226 and phototransistor 468 is configured to capture light 470 reflected by the card. LED 472 has a peak wavelength that matches the peak absorption wavelength of the infrared ink used to print the media coding.

As an alternative, the optical encoder can be configured as a 'quadrature encoder' to sense the direction of media movement. The quadrature encoder includes a pair of optical encoders spatially positioned to read a clock track 90 degrees from phase. The in phase and quadrature outputs allow the MoPEC 326 to identify the direction of operation as well as the operation of the clock track 434. Since the media conveying direction is a known priori so that the printer controller also controls the conveying motor, a quadrature encoder is generally not required. However, the use of quadrature encoders can help separate the bidirectional motion detection mechanism from the motion control mechanism.

94 shows a block diagram of MoPEC 326. This includes a digital phase locked loop (DPLL) 444 for tracking a clock unique to the clock track (see FIG. 91), a line sync signal generator 448 for generating a synchronization signal 476 from the clock 446, and a data track. A data decoder 450 for decoding the data of 436 is integrated. De-framing, error detection, and error correction may be performed by software running on the general purpose processor 452 of MoPEC, or may be performed by dedicated hardware in MoPEC.

Data decoder 450 uses clock 446 recovered by DPLL 444 to sample the signal from data track optical encoder 442. It can sample a continuous signal from the data track optical encoder 442 or can actually trigger the LED of the data track optical encoder 442 during the sampling period, thereby reducing the overall power consumption of the LED.

The DPLL 444 can be a PLL or can simply measure and filter the period between successive clock pulses.

The line sync signal generator 456 is a numerically controlled oscillator that generates the line sync pulse 476 at a rate that is a multiple of the rate of the clock 446 recovered from the clock track 434. )

As shown in FIG. 92, the print engine may optionally integrate an explicit edge detector 474 to provide longitudinal registration of the card 226 by operation of the printhead 202. In this case, as shown in Fig. 95, the page sync signal 478 is generated to signal a start of printing after counting a fixed number of line sync signals 476 after edge detection. Longitudinal matching is also applied to other card-in detection mechanisms leading to opto-sensors, de-capping mechanical switches, drive shaft / tensile spring contact switches and motor load detectors. Can be achieved by

Optionally, the printer may rely on the media coding itself to obtain a longitudinal match. For example, the printer may rely on the acquisition of a pilot sequence on data track 436 to obtain a match. In this case, as shown in Fig. 96, the printer generates a page sync signal 478 to signal a start of printing after counting a fixed number of line sync signals 476 after pilot detection. The pilot detector 460 consists of a shift register and combination logic to accept the pilot sequence 480 provided by the data decoder 450 to generate the pilot sync signal 482. Depending on the media coding itself, it is possible to provide higher level information for registering the content printed with the netpage tag pattern 438 (see FIG. 91).

As shown in FIG. 97, the data track optical encoder 442 is located adjacent to the first clock data encoder 440, so that the data track 436 (see FIG. 91) is as early and restored as possible. It can be decoded using the clock signal 446. Since the clock must be acquired before printing starts, the first optical encoder 440 is positioned before the printhead 202 in the media feed path. However, since the clock needs to be tracked throughout printing, the second clock optical encoder 464 is located at or the same as the printhead 202. This will be described in more detail below.

73 illustrates a printed card 226 retracted from the print cartridge 148. It will be appreciated that the printed card 226 needs to be manually retracted by the user. Once the trailing edge of the card 226 passes between the drive shaft 178 and the spring protrusion 238, the card is no longer driven along the media feed path. However, since the printhead 202 is less than 2 mm from the drive shaft 178, the driving force of the card 226 protrudes its trailing edge through the printhead 202.

Although the driving force of the card is sufficient to move the trailing edge past the printhead, it is not sufficient to export the card out of the exit slot 150 (FIG. 14). Rather, the card 226 is lightly held by the opposed lock actuator arms 232 when the card pops out of the discharge slot 150 on the side of the mobile phone 100. . This does not simply eject the card from the eject slot 150, but rather retains the card 226 to manually remove the printed card 226 from the mobile phone 100 when the user is convenient. This is important for the practicality of the mobile communication terminal because the card 226 is fed to one side of the mobile communication terminal and then retrieved from the other side, so that when collecting a printed card, users generally change the hand holding the mobile communication terminal. Want. By lightly holding and holding the printed card, users do not have to change hands and are ready to collect the card before the print job is completed (about 1-2 seconds).

Alternatively, the speed of the card can be high enough so that the card exits the outlet slot 123 under the card's own inertia when the card leaves the roller.

Dual Clock Sensor  synchronization( DUAL CLOCK SENSOR SYNCHRONIZATION )

For full bleed printing, a decoder is needed to generate a line sync signal for the entire longitudinal length of the card. Unless the card has a removable strip (described elsewhere herein), the print engine requires two clock track sensors on either side of the printhead. Initially, the line sync signal is generated from a clock signal from a pre-printhead sensor, and then the line sync signal is post-posted before the trailing edge of the card passes through the front printhead sensor. need to be generated by a printhead sensor. In order to switch from the first clock signal to the second clock signal, the second clock signal needs to be synchronized with the first clock signal so as to avoid any discontinuity of the line synchronization signal (which causes printing and artificial consequences).

Referring to FIG. 99, a pair of DPLLs 443 and 444 track the unique clock of a clock track through first and second clock track optical encoders 440 and 464, respectively. During the initial phase of printing, only the first encoder 440 will be examining the clock track and only the first PLL 443 will be locked. As the card passes through the printhead, the card is printed and then a second clock track optical encoder 464 examines the clock track. At this stage, both encoders will be examining the clock track and both DPLLs will be locked. During the final phase of printing, only the second encoder will be examining the clock track and only the second DPLL 443 will be locked.

The output from the first DPLL 440 should be used to generate the line sync signal 476 during the initial stage, but before the end of the intermediate stage, the decoder may output from the second DPLL 444 to generate the line sync signal 476. It should be started using the output of. Since it is generally not practical to space the encoders by an integer number of clock periods, the output from the second DPLL 444 may be phase aligned with the output of the first DPLL 443 before a transition occurs. -align).

To handle the transition, there are four important clock tracking steps. During the first phase, when only the first DPLL 443 is locked, the clock from the first DPLL 443 is selected via a multiplexer 462 to provide to the line sync signal generator 448. do. During the second phase, which is initiated when the second DPLL 444 becomes locked, a phase difference between the two DPLLs is calculated 441 and stored in the phase difference register 445. During the third phase, which is initiated some time after the beginning of the second phase, a signal from the second DPLL 444 is set to a delay 447 set to the phase difference stored in the latch register 445. Is provided through. During the fourth phase, which starts at a certain time after the beginning of the third phase, a delayed clock from the second DPLL 447 is selected via the multiplexer 462 and provided to the line synchronization signal generator 448.

101 shows signals that control clock tracking steps. Lock signals 449 and 451 are generated using the lock detection circuit of DPLL 443 and 444. Alternatively, the PLL lock is estimated as it approaches the positional information of the cards for the two encoders 440 and 464. Two phase control signals 453 and 455 are triggered by lock signals 449 and 451 and also controlled by a timer.

Indeed, rather than explicitly delaying the second PLL clock, it should be noted that the delayed clock can be generated directly by a digital oscillator taking the phase difference into account.

2 drive shaft versions ( TWO DRIVE SHAFT VERSION )

Protruding the card 226 past the printhead 202 by the propulsion force allows for a compact single drive shaft design. However, as long as the card leaves the drive shaft 178, the deceleration of the card 226 makes the generation of the correct line sync signal 476 to the trailing edge much more difficult. If the simplicity of the device is not very important, the second drive shaft behind the printhead can keep the speed of the card constant until printing is complete.

110 and 114 show a dual drive shaft embodiment. First, referring to FIG. 110, the print cartridge 148 includes a first drive shaft 178 and a drive roller 176, and as in the previous configuration, the cartridge 148 is supported by the cradle 124. . However, cradle 124 supports small drive wheel 488 on second drive shaft 486, drive roller 492, and sprung shaft 489. The second drive shaft 486 uses a spike wheel 488 instead of a media guide similar to the spring finger 230 of the first drive shaft 178 to avoid soiling any less dry ink. 111 through 113 show cartridges installed in the cradle. The central drive roller 490 mounted at the end of the cradle abuts on both the first and second drive rollers 176 and 492 simultaneously. This guarantees a synchronized drive speed. The central drive roller 490 may be driven by the piezoelectric or electric motor drive system described above.

Section A-A shown in FIG. 114 best represents the media feed path through the cartridge / cradle assembly. When the trailing edge of the card 226 deviates from the first drive shaft 178, the second drive shaft 486 continues to pull the card past the printhead 202 at the same speed in principle. Since the line synchronization signal generated using the clock track is constant, it is not difficult for the MoPEC chip to print the printed material in the longitudinal direction along with the trailing edge. Simultaneously with printing, the MoPEC chip can stop the center drive roller 490 so that the card is held in a nip between the second drive shaft 486 and the spike wheel 488 for user retrieval. have. Alternatively, the card can be fed back in the inlet slot for reverse user recovery.

Of course, in some embodiments it will be appreciated that there is no provision for clock tracks and / or encoded data, such as linear tracks or netpage tags.

Where no (explicit or implicit) clock track is provided, optical, magnetic or electrical feedback, including feedback from one or more transducers combined with one or more rollers or other instruments Other instruments such as may be used to determine the position and speed of the card before and / or during printing. Where no format of encoded data is provided, the printer simply prints on any type of print media that can be inserted and printed. Both options ameliorate various problems related to quality control of printed output, including media jamming, ink bleeding, and excessive mechanical stress and wear of printer components.

Media encoding ( MEDIA CODING )

The card 226 shown in FIG. 91 has data encoded in the form of a clock track 434, a data track 436, and a Netpage tag pattern 438. The encoded data may provide various functions and these functions are described below. However, not all of the functions listed below can be coded media (along with a suitable mobile communication terminal) to perform various other functions as well. Similarly, not all of these features need to be integrated with the encoded data of the medium. Any one or more of the functions can be combined as appropriate for the application or for applications designed for special print media and / or systems.

if( side )

Before printing can begin, the card can be encoded so that the printer can determine the card side facing the printhead, that is, the front side or the back side. This may be the case for cards with pre-printed graphics (such as advertisements) on the back or with different surface treatments (eg to protect graphics preprinted on the back and / or high quality prints on the front). Is received, the printer is rejected if the card is inserted back-to-front. It also allows the printer to print side-dependent content (such as a photo on the front and a detail photo corresponding to the back).

defense( Orientation )

Before starting printing, the card can be encoded so that the printer can determine the orientation of the card relative to the printhead. This causes the printhead to print the rotated graphic to match the rotation of the preprinted graphic on the back. It also causes the printer to reject the card if it is inserted in the wrong orientation (for graphics preprinted on the back). Orientation can be determined by detecting explicit orientation indicators or by using known orientation information printed for other purposes, such as netpage tags or even preprinted user information or advertisements.

Medium type / size

Before starting printing, the card may be encoded to allow the printer to determine the type of card. This allows the printer to prepare print data or to adjust the drop size according to the color conversion or expected absorbance of the card using a particular printing format, e.g., a particular color profile, depending on the media type. Allow to choose. Before starting printing, the card can be encoded to allow the printer to determine the longitudinal size of the card. This allows the printer to print graphics formatted for the size of the card, such as a panoramic crop of photo that is suitable for a panoramic card.

Before printing

Before starting to print, the card may be encoded to allow the printer to determine whether the face of the card facing the printhead is preprinted. If the card is inserted with a preprinted side facing the printhead before printing begins, the printer can then reject the card. This prevents overprinting. Also, before the printer begins printing, a photo, printed on a card with a preprinted advertisement on the backside, except that there is content suitable for a known margin on another face preprinted (eg, there is a photo description margin). Have them prepare the photo description on the back.

Before starting printing, the card can be encoded so that the printer detects whether printing is complete as required (corresponding to preprinting) on the side facing the printhead. This causes the printer to reject the card, rather than overprinting on already printed graphics, when printing is completed as required before the printing starts, the side facing the printhead.

In theory, the card can be encoded so that the printer determines whether the card is an authorized card before printing starts. This theoretically causes the printer to reject an unauthorized card, before the printing starts, at which time the quality of the card is not yet known and the quality of printing cannot be guaranteed.

location( Position )

Before starting printing, the card can be encoded so that the printer determines the absolute position of the card longitudinal direction with respect to the printhead. This allows the printer to print match graphics with the card. This can also be achieved by other methods, for example by directly detecting the leading edge of the card.

Before starting printing, the card can be encoded so that the printer can determine the absolute lateral position of the card relative to the printhead. This allows the printer to print and match graphics with the card. This can also be accomplished by other methods, for example by providing a well-maintained paper feed path and / or by detecting the side edges of the card.

During printing, the card can be encoded so that the printer follows the longitudinal position of the card relative to the printhead, or the longitudinal velocity of the card relative to the printhead. This allows the printer to print match graphics with the card. This can also be achieved by other methods, for example by coding and tracking the moving part of the transport mechanism.

During printing, the card can be encoded so that the printer follows the transverse position of the card relative to the printhead, or the transverse velocity of the card relative to the printhead. This allows the printer to print the graphic by matching it with the card. This can also be accomplished by other methods, such as by providing a snug paper path and / or by detecting the side edges of the card.

Invisibility ( Invisibility )

The code may be placed on the card surface or within the card such that the code is hardly visible to the average human eye. This prevents the sign from being damaged by the printed graphic.

Fault tolerance range Fault Tolerance )

Before the surface contamination or damage reaches the expected amount, the code can be sufficiently fault-tolerant so that the printer can obtain and decrypt the code. This prevents the printer from rejecting the card or causing the printer to produce a substandard print because of the expected amount of surface contamination or damage.

Card and printer alternatives ( CARD AND PRINTER ALTERNATIVES )

In view of the wide range of functionality that a suitable M-print printer and compatible card can provide, various designs that can be substituted for printers, cards, and code are described below. In addition, this list is not intended to be exhaustive, but rather merely examples of some possible variations on the configurations shown elsewhere in this specification.

self Clocking  Data track ( Self - Clocking Data Track )

As an alternative to using separate clocks and datatracks, the datatrack may be self-clocking and the clock may be recovered from the datatrack for other purposes such as line sync generation. have. FIG. 98 shows the layout of the same reference numerals as described with respect to the card 226 shown in FIG. 91 except for using the self-clocking data track 500. This self-clocking datatrack 500 may use other self-clocking schemes such as Manchester phase encoding or return to zero (RZ). The encoding of the data is described in more detail in “Linear Encoding” below.

99 shows a block diagram of a corresponding MoPEC chip in which DPLL 444 operates as a self-clocking datatrack 500 rather than an individual clock track.

Self-clocking datatrack 500 eliminates the need for separate clock and data optical encoders and reduces the impact that individual clock and data tracks have in the area of netpage interaction. The disadvantage of self-clocking datatracks is that they encode data at half the rate of explicitly clocked datatracks.

In subsequent media coding variations, including individual clocks and datatracks, the self-clocking datatrack 500 may also be used, even when not explicitly as mentioned above.

Read step before the print step ( Reading Phase before Printing Phase )

Minimal media coding is designed to be read during printing rather than before printing. The information encoded in the data track 435 is generally not valid until after the printing is completed. For example, a printer generally cannot use a digital signature to verify the netpage identifier and the validity of the card 226 before printing.

The printer transfers the card 226 in a forward direction past the datatrack optical encoder 442 before decoding, decrypts some or all of the datatrack 436, and then starts the card. Access to the data track information can be obtained by transferring the card to return to the position. This may also provide the printer with a larger space to approve a robust page sync indicator of the datatrack 436, as described above with respect to the card shown in FIG. 91. The information in the datatrack can also be effectively extended to provide some or all of the other functions in some of the media codes.

Explicit face and bearing indicators ( Explicit side and Orientation Indicators )

The minimum medium code does not explicitly encode the face of the card 226. The printer determines from the presence of the clock track 434 that the face of the card is facing the printhead. The minimum medium code does not make the orientation of the card accessible to the printer prior to printing, unless the printer performs the reading step as described above. Instead, it is believed that the minimum coding allows the user to present the card in any orientation (except flipping).

Rather than allowing printing in both orientations, the printer may reject cards with the wrong orientation. To allow this, the media code must include an orientation indicator accessible to the printer before printing. As shown in FIG. 102, the advantage of this is that a narrower area of the card is used for clock 434 and datatrack 436, resulting in a wider area available for netpage interaction.

Rather than relying on the absence of a clock track on the front of the card for the inducible side, the media code may instead include explicit side indicators on the front. The table below gives an example of 8-bit codes that can be used to code the plane and bearing indicators to prevent failure.

The code has five minimun distances, so the code can correct two errors. Longer and more robust code is obviously executable.

Indicator 502 may be included in the datatrack immediately after pilot. The face and orientation indicators 502 also allow the pilot and code to be coded by designing codes of appropriate length that are at most apart from each other as well as from their own preamble-prefixed shift. Can be combined.

Like the datatrack 436, the face and orientation indicators 502 can be explicitly clocked by the clock track 434, or self clocking.

Rather than clocked at the same rate as the rest of the datatrack 436, the face and orientation indicators 502 may be gross markers that can only recognize roughly a given longitudinal print match. For example, the two bits needed to encode the plane and orientation can be pulse-position modulated (PPM) using the gross mark (eg 0.5 mm length) for each pulse.

The table below defines some possible PPM options. In this table, 0 represents the total space and 1 represents the gross mark.

Data tracks on both sides ( Data Track on Both Sides )

Rather than relying on all feasible future printers with optical encoders mounted on the back of the card, the media code may instead include a clock 434 and datatrack 436 on the front as well.

Cards with detachable strips ( Card with Detachable Strip )

The apparatus shown in Figs. 91 to 97 uses two clock track optical decoders 440 and 464, one to secure a clock obtained before printing starts, and the other to keep track of clock tracking until printing is finished. It is to insure (clock tracking). Alternatively, the card 226 may extend in the form with a tear-off strip 504, as shown in FIG. 103, with a clock track 434 extending over the strip.

The tear-off strip 504 is made of part of the card 226 and the remainder is connected to the card through the perforations until separated by the user, as shown in FIG. 104. Perforation is fine enough to leave a soft edge to the touch.

By extending the length of the card through a strip attached to the leading edge of the card, a single clock track linear encoder 464 located upstream of the printhead 202 (see FIG. 97) is capable of clock acquisition just before printing starts. Rather, it is sufficient to support clock tracking throughout printing.

The second major advantage of the strip 504 is that the card is finally driven through the printhead without the single drive shaft 178 passing through the printhead, i.e. without requiring the second drive shaft 486, or using only the driving force of the card throughout printing. The card can be driven without expecting to "fly" a short distance undriven.

To assure correct recognition of the card 226 after the tear-off strip 504 has been removed, the media symbol includes a second face and orientation indicator 508 that is revealed when the tear-off strip 504 is removed. can do. This is shown in FIG. 103.

Tear-off strip 504 may produce garbage. To alleviate this, each tier-off strip can be used as a lottery ticket when handed over to a retailer selling M-print media. One of the many netpage-enabled devices described in the assignee's cross-referenced netpage applications and patents can be used to inspect the strip passed by the retailer.

Cards with square corners ( Card with Square Corners )

Whether the card 226 has a removable strip 506, it may be desirable to have a card with square corners rather than rounded corners. Photo printing is arguably the most noteworthy application of M-Print. Both photos and business cards usually have square corners. In addition, the presence of the tear-off strip 504 causes additional motivation to use square corners rather than round corners. 106 and 107 show card 226 with rectangular edge 510 and tear-off strip 504.

Side data track ( Lateral Data Track )

Rather than transporting the card 226 forward twice (as described above) to perform the reading step before the printing step, the media coding may incorporate side data tracks rather than vertical data tracks.

As shown in FIG. 108, the side data track 514 may be read by a linear image sensor, whether explicitly clocked or self-clocked. Related technologies and devices are described in USSN 11 / 084,796 (Registration No. 011US), filed March 21, 2005, as Applicant's pending application. The side data track 514 can ideally be placed along the leading edge 516 of the card, so that it can be fully decoded before printing. This may lie on the tear-off strip 504 of the data track 514 that may be applied on a netpage tag pattern that is appropriately on the card (ie, at the retained position of the card 226). Eliminate shock. In this case, the tear-off strip 504 needs to be on the leading edge 516, rather than the trailing edge 518 of the card. This in turn refers to that the clock track optical encoder 464 is located downstream rather than upstream of the printhead 202 (see FIG. 97). The appropriate card still has a self-clocking face and azimuth indicator 502 and a single clock track 434 on each face, but no data track. The side data track 514 may provide a basis for accurate side registration, particularly to provide accurate side registration between the netpage tag pattern 438 and printed visual content.

Side tracks can also be added to non-tear-off versions of the card.

The linear image sensor extends laterally along the media feed path in front of the printhead with respect to the media feed direction. This image sensor is a linear array of active pixel sensors, each sensor reading coded data within a sample area within the card. The sample region corresponds to the 'Mnem region' described in detail in US Patent 6,870,966 (Registration No. NPS001US), filed 2000.5.23 as Applicant's pending application, the contents of which are incorporated herein by cross-reference. . 109 shows a detailed physical view of a Memjet printhead IC with an integrated image sensor. For simplicity, this figure generally shows only 1600 dpi nozzles 600, with the combined actuators shown at 601 and the drive circuit mounted adjacently. Note that since the 32-micron width of each nozzle unit cell exceeds the 16-micron dot pitch required for 1600 dpi printing, each row of nozzles consists of two staggered half-rows 602, 603. The sampling rate N is 2.5 in the device shown above.

Although the sample region may use a single printed dot to represent a single coded bit, one or more printed dots may also be used to represent a single coded bit. For example, the sample area may use a 2x2 array of printed dots to represent a single bit. Thus, if the printer resolution is 1600 dpi, the sample area resolution is only 800 dpi. In some applications, reducing the print resolution of the sample area may provide rougher performance, such as in the presence of a surface deterioration or a particular source of damage.

If the area resolution is lower than the printer resolution, the ratio of the number of pixels to the number of nozzles can thus be reduced, and larger pixel sensors can be employed. For example, in the case of the Memjet printhead shown in FIG. 109, a 12.8 micron pixel sensor may be used instead of two 6.4 micron pixel sensors.

Automatic printing ( Automatic printing )

In one aspect, the mobile terminal is configured to automatically start printing when the print medium is inserted into the paper feed path. Mechanical or optical sensors (or combinations thereof) can be used to determine when this has happened.

The device can automatically print in several ways. In one example, the device automatically prints the current document or file upon current use by the user. This would in most cases be the document or application currently being shown on the display of the device. For example, if the user is reading an email or SMS appearing on the display, inserting a print medium will cause the email or SMS to be printed.

Optionally, the user may instruct the mobile terminal to print a document or file and then insert the print media. The mobile terminal will then automatically print the next print job in the queue. Optionally, the device may request confirmation of the job to be printed, especially if excess time has passed since the job was queued.

Preferably, the print mode is selectable by the user, thereby explicitly allowing automatic printing to be activated (print immediately without confirmation), partially activated (waiting for confirmation) or deactivated (print from the user). Wait for the command).

Possible M-print configurations ( POSSIBLE  M- PRINT CONFIGURATION )

From the above alternative embodiments, there are many possibilities for the physical configuration of the components in the M-print printer. Each possibility has its own advantages and disadvantages that can be evaluated when choosing a configuration for a particular M-print application. The selection of the possible configurations and their associated advantages are described below with reference to the schematic diagrams shown in FIGS. 115-120. These figures place parts with reference to the media feed path and the following M-print variables.

Tracking Tail Fly Period (TTFP): The period of time during which MoPEC does not receive card tracking information from coding.

Drive Tail Fly Period (DTFP): The time period between the departure of the card from the drive shaft and the card's seat in the media path.

Drive Settling Period (DSP): The period of time between the initial engagement with the drive shaft of a card and the card being accelerated to steady state speed.

Tracking Settling Period (TSP): The time period required for the optical encoder to lock onto markings on the clock track.

Media Coding Dead Zone (MCDZ): The portion of the data track shown to the data encoder while the card is not running. Reading data from this MCDZ may be unpredictable.

Ink Drying Time (IDT): The minimum period of time after which ink droplets are printed on a card that these printed dots can be contacted without compromising print quality.

Between as shown in Figure 115, the print head 202 is placed an encoder (440) in front of the driving shaft 178 in front of the print head and the drive shaft: (Printhead Encoder-Drive) encoder-drive printheads Minimize the distance. This configuration also uses minimal components. This allows for a compact design.

Drive-encoder-print head (Drive-Encoder - Printhead): as shown in Figure 116, the driving shaft 178, an encoder 440, and placing the print head (202) continuously along the media path, the leading edge detection To simplify.

Encoder-drive the print head-drive (Encoder - Drive - Printhead - Drive): the configuration shown in Figure 117 is the same as adding the second driving shaft 486 to that of Figure 115. This eliminates DTFP and simplifies handling of TTFP.

Encoder-drive the print head-drive (Encoder - Drive - Printhead - Drive): the configuration shown in Figure 118 is the same as adding the second driving shaft 486 to that of Figure 116. This eliminates DTFP, MCDZ and simplifies handling of TTFP.

Encoder-drive-printhead-encoder (Encoder-Drive-Printhead-Encoder): the configuration shown in Figure 119 is the same as adding a second encoder 464, as in Figure 115. This eliminates TTFP and simplifies handling of DTFPs.

Drive-encoder-printhead-encoder (Drive-Encoder - Printhead-Encoder): the configuration shown in Figure 120 is the same as adding a second encoder 464, as in Figure 116. This eliminates TTFP, MCDZ and simplifies the handling of DTFP.

It should be noted that minimizing DSP and TSP, maximizing TTFP and DTFP, and avoiding MCDZ and IDT are general design goals for these configurations.

Linear coding ( LINEAR INCODING )

Kip is the assignee's internal name for a template for grading a strong one-dimensional optical encoding scheme for storing small amounts of digital data on a physical surface. It optionally incorporates error correction to cope with actual surface degradation.

The specific encoding scheme is defined by specializing the following Kip template. Variables include data capacity, clocking scheme, physical scale, and level of redundancy. Kip readers are also typically specialized for specific coding schemes.

Kip encoding may be designed to be read through a simple optical detector while transferring the encoded medium past the detector. Therefore, this coding generally moves parallel to the conveying direction of the medium. For example, keep coding can be read from a print medium during printing. In a preferred embodiment, keep coded data is provided along at least one longitudinal edge of the print medium to be printed within the mobile terminal, as described above. In this preferred form, the keep coded data is printed with infrared ink, making it invisible or at least difficult to see with the naked eye.

Keep coding is generally printed on a surface, but may be placed on or in the surface by other means.

Summary of Keep Variables SUMMARY OF KIP PARAMETERS )

The following table summarizes the variables needed to specialize Kips. These variables should be understood within the context of this document.

The following table summarizes the error correction variables:

variable unit Explanation m beat Size of Reed-Solomon Symbol k symbol Size of Reed-Solomon codeword data t symbol Error-correction capacity of Reed-Solomon code

Keep coding ( KIP) ENCODING )

Keep coding encodes a single bitstream of data, as shown in FIG. 121, and includes a number of separate and independent layers. The matching layer frames the bitstream to allow synchronization and simple error detection. The modulation and clocking layer encodes the bits of the frame according to the clocking information to allow bit recovery. The physical layer represents the modulated and clocked frame using optically-readable marks.

An optional error correction layer encodes the bitstream to allow error correction. An application may choose to use the error correction layer or implement itself.

Keep coding is designed to allow serial decoding and thus has an accompanying time dimension. By appointment in this document, the time axis points to the right. However, specific keep coding may be physically represented in any orientation suitable for the application.

Match frame FRAMING )

As shown in FIG. 122, a keep frame includes a preface, a pilot, the bitstream data itself, and a cyclic redundancy check (CRC) word.

The _preamble consists of a sequence of zero length L _preamble . This preamble is long enough to allow the application to begin the keep coding somewhere in the preamble, that is, long enough to allow the application to know a priori the location of at least a portion of the preface. Thus, the length of this preamble sequence in bits is derived from the application-specific preamble length l _preamble (see equation 8).

The pilot consists of a unique pattern that allows the decoder to synchronize with the frame. This pilot pattern is designed to maximize the binary Hamming distance from its own abstract shifts, preceded by preface bits. This allows the decoder to use the most likely likelihood decoder to recognize the pilot even if a bit error exists.

The preamble and pilot together ensure that any bit sequence that the decoder detects before detecting the pilot is maximally away from the pilot.

The pilot sequence is 1110 1011 0110 0010. The length L _pilot is 16. The maximum distance from his own preface-shifts is nine. Therefore, it can be recognized reliably when up to 4 bit error exists.

The length L _data of the bitstream is known a priori by the application and thus becomes a parameter. The bitstream is not encoded in the frame. In the bitstream, the first, that is, the leftmost most significant bit is coded.

Cyclic redundancy code (CRC) is CCITT CRC-16 (not known here because it is known to those skilled in the art) calculated from bitstream data, and allows the decoder to specify if there is an error in the bitstream. . The length of the _CRC ( L _CRC ) is 16. CRC is calculated from left to right on the bitstream. The bitstream is padded with zero bits during CRC calculation, making its length an integer multiple of 8 bits. Padding is not encoded in the frame.

The frame length in bits is:

(Equation 1) L _frame = L _preamble + L _pilot + L _data + L _CRC

(Equation 2) L _frame = L _preamble + L _data + 32 .

Modulation and Clocking (( modulation and clocking )

The kip encoding means modulates a frame bit sequence of a frame to produce a sequence of abstract marks and spaces. These are physically identified by the physical layer.

The keep coding means support both explicit and implicit clocking. When the frame is explicitly clocked, the encoding includes a clock sequence encoded and separated in parallel with the frame, as shown in FIG. The bits of the frame are then encoded using conventional non-return-to-zero (NRZ) coding. Zero bits are represented by spaces, and one bit is represented by a mark.

The clock itself consists of a column of alternating marks and spaces. The center of the clock mark is aligned with the bit center of the frame. The frame is encoded so that the bit rate of the frame is two bits per clock period, ie, twice the clock rate.

The clock initiates some clock period C _clocksync before frame commences so that the decoder acquires clock synchronization before frame commencement. C _clocksync depends on the characteristics of the PLL used by the decoder, resulting in a reader-specific parameter.

When encoding is explicitly clocked, the corresponding decoder incorporates an additional optical sensor to detect the clock.

When a frame is implicitly clocked, the bits of the frame are encoded using Manchester phase encoding. Zero bits are represented by space-mark transitions and one bit is represented by mark-space transitions, with two transitions left-to-right. It is prescribed. Manchester step encoding causes the decoder to extract the clock signal from the modulated frame.

In this case, the preamble is extended by C _clocksync to cause the decoder to acquire clock synchronization before searching for the pilot.

Assuming that the marking frequencies are the same, the bit density of the explicit clocking encoding is twice the bit density of the implicit clocking encoding.

The choice between explicit and implicit clocking depends on the application. Explicit clocking has the advantage of providing greater longitudinal data density than implicit clocking. Explicit clocking requires two optical sensors, but implicit clocking has the advantage of requiring only a single optical sensor.

The parameter ( b _clock ) indicates whether the clock is negative ( b _clock = 0 ) or quantitative ( b _clock = 1 ). The length in clock cycles of a modulated and clocked keep frame is:

( _Frame 3) C _frame = C _clocksync + L _frame / (1 + b _clock )

Physical representation ( PHYSICAL REPRESENTATION )

Keep coding represents a physically modulated and clocked frame as a strip having both a longitudinal extent (ie, in the coding direction) and a lateral extent.

The keep strip always contains a datatrack. If the keep stripe is explicitly clocked rather than implicitly clocked, it includes this or a clock track.

In general, although a specific decoder can handle a certain amount of jitter and drift well, the clock cycle in the keep strip is nominally fixed. In addition, jitter and deviation may be introduced by a transport mechanism in the reader. The amount of jitter and deviation supported by the decoder is unique to the decoder.

Appropriate clock periods depend on the characteristics of the media and marking mechanism and on the characteristics of the reader. This is therefore an application specific parameter.

The abstract marks and spaces correspond to this, allowing the decoder to distinguish between marks and spaces by having physical indications that cause distinct intensity when sampled by a matched optical sensor. The spectral characteristics of the optical sensor and, in addition, the physical characteristics of the physical marks and spaces are application specific.

The transition time between the mark and the space is nominally zero but is allowed up to 5% of the clock period.

Typically, abstract marks are represented by physical marks printed using inks with specific absorption properties, and also abstract spaces are typically lacking physical marks, i.e. broadband reflective (white) paper. This is caused by the absorption characteristics of the substrate. However, keeps are not defined like this.

The length of the _mark ( l _mark ) and the length of the _space ( l _space ) are nominally the same. Appropriate marks and spaces depend on the characteristics of the media and marking mechanism and the characteristics of the reader. Therefore, their lengths are application-specific parameters.

의 인수(factor)까지 차이가 있을 수 있어, 마크인쇄를 특정 프린터의 최대 도트해상도의 절반까지 조정하도록 한다. 상기 인수는, 도면에 도시된 바와 같이, 단일치(unity)와 수직위치에 따른 한계치(limit) 사이에 변동한다.The length of the mark and the length of the space, as shown in Fig. 125,

There may be differences in the factor of, so that the mark printing is adjusted to half of the maximum dot resolution of a particular printer. The factor varies between a unity and a limit depending on the vertical position, as shown in the figure.

The sum of the length of the mark and the length of the space is equal to the clock period:

(Equation 4) l _clock = l _mark + l _space

The total length of the strip is:

(Eq. 5) l _strip = l _clock × C _frame

The minimum width W _mintrack of the data track (or clock track) in the strip depends on the reader. Therefore, this is an application specific parameter.

The required width ( W _track ) of the data track (or clock track) in the strip is the maximum allowable lateral misregistration ( W _misreg ) for the transport path through the corresponding optical sensor and the maximum allowable width of the strip. It is determined by the maximum allowable rotation (α):

(Equation 6) W _track = W _mintrack + W _misreg + l _strip tan α

The maximum transverse width and the width of rotation depend on the characteristics of the media and marking mechanism, and on the specifics of the leader. Therefore, it is an application-specific parameter.

The width of the strip is:

(Equation 7) W _strip = (1 + b _clock ) × W _track .

The length of the preamble sequence in bits is derived from a parameter that specifies the length of the preamble:

(Expression 8)

Error correction ( ERROR CORRECTION )

Keep coding optionally includes error correcting coding information to cause the decoder to correct the bitstream data in which an error has occurred due to surface damage or surface dirt. As shown in FIG. 126, Reed-Solomon redundancy data is added to a frame to calculate an extended frame.

The Kip Reed-Solomon code has the symbol size (in bits) ( m ), data size (in symbols) ( k ), and error correction capacity (in symbols), as described below. The characteristic is given by ( t ). The Reed-Solomon code is selected according to the size ( L _data ) of the bitstream data and the expected bit error rate. The parameters of the code are therefore application specific.

Surplus data is calculated as a concatenation of bitstream data and CRC. Likewise, this allows the CRC to be corrected.

The bitstream data and the CRC are padded with zero bits during the surplus data calculation, making their length a multiple of the symbol size m . Patting is not encoded in the extended frame.

The decoder verifies the CRC before performing Reed-Solomon error correction. If the CRC is valid, the error correction is temporarily omitted. If the CRC is invalid, the decoder performs error correction. Then verify the CRC again to confirm the success of the air purification. The length of the Reed-Solomon codeword in bits is:

L _codeword = (2t + k) x m .

The number of Reed-Solomon codewords is:

이다.(Eq. 10)

to be.

The length of surplus data is:

(Equation 11) L _ECC = s × (2t × m) .

The length of the extended frame in bits is:

(Formula 12) L _{extendedframe} = L _frame + L _ECC .

Reed-Solomon Coding ( REED - SOLOMON CODING )

의 리드-솔로몬코드(n,k)는

Reed-Solomon code of (n, k) is

N = 2 ^m - 1 in:

(Bits on) the symbol size (m), (symbols on), characterized by a code word size (n) and (symbols on), data size (k) is given.

The error correction capacity of the code is

에서,(Eq. 14)

in,

t symbol.

In order to minimize the redundancy overhead of a given error correction capacity, the number of surplus symbols (nk) is chosen to be even, ie:

2t = n-k .

Reed-Solomon code is well known and understood in the field of data storage and is not described in detail here.

The data symbols and redundant symbols of the code are indexed from left to right according to the power of the terms of the polynomial corresponding thereto, as shown in FIG. It should also be noted that the data bits are indexed in the opposite direction, from right to left.

The data capacity of a given code can be reduced by avoiding code, i.e. systematically removing a subset of data symbols. The lost symbol can then be treated as deletion during decryption. In these cases:

N = k + 2t < ^2m - 1 .

Longer codes and codes with larger error correction capacities are more expensive to decode computationally than shorter codes or codes with lower error correction capacities. Multiple codewords can be used to encode the data where constraints of the application limit the complexity of the code and where the required data capacity exceeds the capacity of the selected code. Codewords are interleaved in order to burst errors with maximum codeword resilience.

To maximize the utility of keep coding, the bitstreams are encoded continuously and in sequence within the frame. To harmonize the requirements of interleaving with the requirements for sequential and ordered, the bitstream is deinterleaved for the purpose of calculating Reed-Solomon surplus data, and then re-interleave before being encoded in the frame. )do. This maintains the order and continuity of the bitstream and also at the end of the extended frame yields a separate continuity block of interleaved redundant data. A kip interleaving scheme is defined in detail below.

Keep Reed-Solomon codes have a primitive polynomial specified in the following table:

Symbol size (m) Basic polynomial 3 1011 4 10011 5 100101 6 1000011 7 10000011 8 101110001 9 1000010001 10 10000001001 11 100000000101 12 1000001010011 13 10000000011011 14 100000001010011

The table entrance shows the efficiency of the basic polynomial in order of highest efficiency on the left. Thus, the basic polynomial when m = 4 is:

이다.(Eq. 17)

to be.

Keep Reed-Solomon codes have the following generation polynomials:

(Eq. 18)

For interleaving purposes, the source data D is divided into a sequence of m -bit symbols and padded to the right with zero bits to yield a sequence of u symbols, consisting of an integer multiple of k symbols when s is the number of codewords:

U = s x k

(Eq. 20) D = { D ₀ , ..., D _{u -1} }

Then, each symbol in this column is mapped to a symbol of the corresponding ( i _th ) interleaved codeword ( W ):

(Eq. 21)

The resulting interleaved data symbols are shown in FIG. 128. It should be noted that this is a match in place of the source data to the codeword and not a rearrangement of the source data.

The symbols of each codeword are de-interleaved prior to encoding the codeword, and the resulting redundant symbols are re-interleaved to form a redundant block. The resulting interleaved redundant symbols are shown in FIG. 129.

Normal Netpage  Explanation( GENERAL NETPAGE DESCRIPTION )

The netpage interaction function provides printed user interfaces to enable various phone functions and applications, such as enabling a specific mode of operation of a mobile terminal or interacting with an application calculator, a general keypad to the mobile terminal, It can be used to provide keyboard and tablet input means. These interfaces can be pre-printed and bundled with the phone, where the phone is integrated into the printer, purchased separately (as part of a ringtone or theme-like customizing phone operation), or printed as needed. Can be.

The printed Netpage business card provides a good example of how the various functions are usefully combined in a single interface. These features include:

There is.

All these functions can be used only by themselves.

A business card may be printed by a mobile terminal user and used for introduction purposes to others or from a business related web page for use by the mobile terminal user himself. They can also be pre-printed.

As will be described below, the main advantage of the integration of a netpage pointer or pen into another terminal is in synergy. A netpage pointer or pen integrated into a cell phone, smartphone or communication function PDA, for example, allows the terminal to act as a netpage pointer and as a relay between the pointer and the cell phone network and even the netpage server. When the pointer is utilized to interact with the page, the target application of the interaction can display information on the phone's display and, in addition, initiate interaction with the user through the phone's touch screen. . The pointer is most usefully constructed by having a "nib" in one corner of the telephone body, so that the user can easily manipulate the telephone to point to a tagged surface.

The phone can be integrated with a marking nib and can optionally integrate a continuous force sensor to provide maximum netpage pen functionality.

In the following example of the interaction of a netpage, how a sensing device in the form of a mobile terminal of the netpage function interacts with coded data on a print medium in the form of a card. If the preferred form of print media is a card created with a mobile terminal or another mobile terminal, it may also be purchased as a commercially preprinted card or provided as part of a commercial business. Also, such a print medium may be, for example, one side of a book, magazine, newspaper or brochure.

The mobile terminal detects a tag using an area image sensor and detects tag data. The mobile terminal uses the sensed data to generate interactive data, which is transmitted to the document server via the mobile communication network. The document server uses the ID to access document descriptions and to interpret the interactions. Under the appropriate circumstances, the document server may send a communication message to the application server and then execute the communication operation.

Typically, users of a netpage pen and a netpage function mobile terminal register with a registration server, and the user is associated with an identifier stored in each netpage pen or netpage function mobile terminal. By sensing the terminal identifier as part of the interaction data, users can be identified so that work or similar activities can be performed.

Netpage documents are created by having an ID server that generates an ID that is sent to a document server. The document server determines the description of the document and then records the relationship between the document description and the ID so that the ID can be used for subsequent modification of the document description.

The ID is then used to generate tag data, which will be described in more detail below, but uses a description of the page and a tag map before the document is printed to a suitable printer.

Each tag is represented by a pattern including two kinds of elements. The first type element is a target. Targets allow the tag to be placed in the coded surface image and also to estimate the stereoscopic distortion of the tag. The second type element is a macrodot. Each macrodot encodes the value of a bit as its presence or absence.

The pattern appears on the coded surface in a manner obtained through an optical imaging system, in particular an optical system that gives a narrowband response in near-infrared. Typically the pattern is printed onto a surface using a narrowband near infrared ink.

In a preferred embodiment, the area typically corresponds to the entire surface of the M-Print card and the area ID also corresponds to the unique M-print card ID. For clarity in the following paper, refer to items and IDs, keeping in mind that the ID corresponds to the area ID.

Surface coding is designed so that an acquisition field of view large enough to ensure the capture of the entire tag is large enough to ensure the capture of the ID area containing the tag. The tag capture itself ensures the capture of tag-specific data as well as the two-dimensional position of the tag within the area. Therefore, the surface coding portion causes the sensing terminal to capture the area ID and tag position during pure local interaction with the coded surface, for example during tapping on a “code” or a pen coded surface. .

Tag structure example ( EXAMPLE TAG STRUCTURE )

A wide range of different tag structures may be used (as described in the Netpage application of the various cross-references of the assignee). Hereinafter, the detail of a preferable tag is described.

130 shows the structure of a complete tag 1400. Each of the four calibration circles 1402 is a target. The tag 1400, and the previous pattern, have four-fold rotational symmetry at the physical level. Each square region 1404 represents a symbol, and each symbol represents four bits of information.

131 shows the structure of a symbol. The symbol includes four macrodots 1406, each of which represents a value of one bit as its presence (1) or absence (0). The macrodot interval is specified by the parameter S throughout this document. The macrodots have a nominal value of 143 μm, based on 9 dots printed at a pitch of 1600 dots per inch. However, this value allows an error of ± 10% depending on the capabilities of the terminal used to calculate the pattern.

132 shows an arrangement of nine adjacent symbols. The macrodot spacing is constant both within and between symbols.

133 shows an arrangement of bits in a symbol. Bit zero b0 has the least importance in the symbol; Bit 3 (b3) is the most important. This arrangement is associated with symbol orientation. The orientation of a particular symbol within tag 1400 is indicated by the orientation of the symbol label in the tag table. In general, the orientation of all symbols in a particular section of a tag has the same orientation, which coincides with the symbol bottom closest to the center of the tag.

Only macrodots 1406 are part of the symbol representation in the pattern. The square outline 1404 of the symbol is used in this document to make the structure of the tag 1400 clearer. 134 shows, via illustration, the actual pattern of the tag 1400 as all bits are set. In fact, it should be noted that all bits of the tag 1400 can never be set.

The macrodot 1406 is a circle having a nominal diameter of nominally (5/9). However, an error of ± 10% in size is tolerable depending on the terminal capabilities used to calculate the pattern.

The target 1402 is a circle having a nominal diameter by nominal (17/9). However, an error of ± 10% in size is tolerable depending on the terminal capabilities used to calculate the pattern.

The tag pattern allows an error of up to ± 10% in proportion, depending on the capabilities of the terminal used to calculate the pattern. Deviations from the nominal ratio are recorded in the tag data to ensure accurate generation of position samples.

Each symbol shown in the tag structure of FIG. 130 has a unique label. Each label consists of an alphabetic prefix and a numeric suffix.

Tag groups ( TAG GROUP )

Tags are arranged in tag groups. Each tag group contains four tags arranged in a rectangle. Therefore, each tag has one of four possible tag types depending on its position in the tag group rectangle. Tag types are labeled 00, 10, 01, and 11 as shown in FIG.

136 shows that the tag groups are repeated with consecutive tiling of tags. Tiling ensures that all four contiguous tag sets contain one tag of each type of tag.

Codeword ( CODEWORDS )

The tag contains four complete codewords. Each codeword is a punctured 2 ⁴ (8,5) Reed-Solomon code. Two codewords are unique for a tag. These are partially referenced and labeled A and B. The tag therefore encodes up to 40 bits of information unique to the tag.

The other two codewords are unique to the tag type, but are common to all tags of the same type within the consecutive tiles of the tag. They are referenced globally, labeled C and D, and subscripted by tag type. Therefore, tag groups encode up to 160 bits of information common to all tag groups in the continuous tiling of tags. A layout of four codewords is shown in FIG.

Reed-Solomon Coding ( Reed Solomon Encoding )

Codewords are encoded using a Reed-Solomon code of punctured 2 ⁴ (8,5). A Reed-Solomon code of 2 ⁴ (8,5) encodes 20 data bits (ie five 4-bit symbols) and 12 redundant bits (ie three 4-bit symbols) in each codeword. Their error-detecting capacity is three symbols. Their error-correcting capacity is one symbol. Further information on Reed-Solomon coding in a netpage environment is provided in US Ser. No. 10 / 815,647 filed April 2, 2004 (Sort No. HYG011US), incorporated herein by reference in its entirety.

Netpage in mobile environment ( NETPAGE  A MOBILE ENVIRONMENT )

138 provides a schematic architecture of the netpage system, which is integrated into local and remote applications and local and remote netpage servers. A general netpage system is extensively described in the assignee's many inventions and pending applications (eg USSN 09 / 722,174 (Reg. No. NPA081US)) and will not be described in detail here. However, many extensions and alternatives to the general netpage system are used to implement some of the various netpage based functions to the mobile terminal. This applies to both netpage-related sensing means for coded data on a print medium being printed (or about to be printed), and to a netpage function mobile terminal with or without a printer.

Referring to FIG. 138, the netpage microserver 790 running on the mobile phone 1 implements a limited set of netpage functions oriented towards interpreting clicks rather than interpreting normal digital ink. to provide. When the microserver 790 receives the click event from the pointer driver 718, it interprets it in the usual netpage manner. This includes retrieval of the page description associated with the click impression ID and hit testing of the click position against the interactive elements in the page description. This allows the microserver to identify the command element and send the command to the application program specified by the command element. This functionality is described in much of the earlier cross-referenced netpage application.

 The target application may be a local application 792 or a remote application 700 accessible via a network 788. Microserver 790 passes the command to run the application or to begin execution if the application has not yet run.

If the microserver 790 receives a click for an unknown impression ID, then the microserver can then click the network-based netpage server 798 to handle the click using the impression ID. ) And also sends a click to the server for interpretation. The netpage server 798 may be on a separate intranet accessible to the mobile communication terminal or on the public internet.

For known impression IDs, the microserver 790 may interact directly with the remote application 700 rather than via the netpage server 798.

If the mobile terminal includes a printer, an optional printing server 796 is provided. The print server 796 is executed in the mobile phone 1 and receives print requests from remote applications and netpage servers. In some cases, the print server receives a print request from an untrusted application, in which case the application needs to present a single-use printing token previously issued by the mobile communication terminal.

The display server 704 running on the mobile communication terminal receives a display request from remote applications and netpage servers. When the display server 704 receives a display request from an unauthorized application, the application needs to present a one-time display token issued by the mobile communication terminal. The display server 704 controls the mobile communication terminal display 750.

As shown in FIG. 139, the mobile communication terminal can act as a relay for a netpage stylus, pen, or other netpage input terminal 708. If the microserver 790 accepts a digital ink for an unknown impression ID, the microserver identifies the network-based netpage server 798 that can handle the digital ink using the impression ID. Send to server for interpretation.

The microserver 790 may be configured to have some capability for the interpretation of the digital ink, although the function of the digital ink analysis is not necessary. For example, only check boxes and drawings fields can interpret the associated digital ink, perform rudimentary character recognition, or execute the character recognition with the help of a remote server. Can be.

In addition, the microserver may be configured to route the digital ink captured through the netpage "tablet" to the operating system of the mobile communication terminal. The Netpage tablet may be a separate surface, may be pre-printed or on demand printed, or may be overlayed or underlayed on the mobile terminal display.

The Netpage pointer is developed and used for the Netpage pen and incorporates the same image sensor and image processing ASIC (hereinafter referred to as "Jupiter" in detail). The jupiter reacts to the contact switch by activating the illumination LED and capturing an image of the tagged surface. The jupiter then informs the mobile terminal processor that it has been "clicked". Netpage pointers integrate into a design similar to Netpage pens, ideally having a smaller form factor. Smaller form factors are achieved with more complex multilens designs, as described below.

Netpage  Obtain media information directly from tags ( Obtaining Media Information Directly from Netpage Tags )

The media information can be obtained directly from the netpage tag. This has the advantage that a data track is needed at all or only minimally, especially since the net page identifier and digital sign can be obtained from the net page tag pattern.

The netpage tag sensor can read tag patterns from a snapshot image. This has the advantage that the card can be captured as it enters the paper path, if necessary, before engaging the carrier and even before the printer controller is activated.

The netpage tag sensor that can read a tag when the medium enters or passes the media feed path is described in detail in the following Netpage Clicker related description (see FIGS. 140 and 141).

Conversely, the advantage of reading tag patterns during transfer is that the printer can obtain accurate information about the lateral and longitudinal registration between the netpage tag pattern and the visual content printed by the printer. Can be. A single captured image of the tag can be used to determine registration in one or both directions, preferably determining the registration based on at least two captured images. Images may be captured continuously by a single sensor, or two sensors may capture images simultaneously or sequentially. Various averaging approaches may be employed to determine more accurate positions in one or both directions from two or more captured images than would be effected by echo in a single image.

 If the tag pattern can be rotated relative to the printhead, the tag pattern is read in determining the rotation due to either the manufacturing tolerance of the card itself or the manufacturing error on the paper path. It is advantageous to. The printer can then report the rotation to the netpage server, which, when the printer finally interprets the digital ink captured through the card, can record and use the interpretation. Although a single captured image of a tag can be used to determine the rotation, it is desirable to determine the rotation based on at least two captured images. Images can be captured continuously by a single sensor or two sensors can capture images simultaneously or continuously. Various averaging methods may be employed to determine more accurate positions from two or more captured images than would be valid by reverberation of a single image.

Netpage  option( NETPAGE OPTIONS )

The following media coding options relate to netpage tags. Netpages are described in more detail later.

Netpage  Tag bearing ( Netpage Tag Orientation )

The card may be coded to allow the printer to determine the netpage orientation on the card in relation to the printhead, possibly before starting printing. This allows the printer to rotate the page graphics to match the orientation of the netpage tags on the card prior to starting printing. The printer may also report the orientation of netpage tags on the card for recording by the netpage server.

Netpage  Tag location ( Netpage Tag Position )

As mentioned above, if lateral and longitudinal matching and motion tracking are achieved by other means rather than through media coding, then any misregistration between the media coding itself and the printed content The error may be specified as a lateral and / or longitudinal matching error between the netpage tag and the printed content, due to either an error in the manufacturing of the card itself or a paper path error of the printer. This time this can result in a degraded user experience. For example, it may be assumed that the hyperlink area is not registered correctly with the visual representation of the hyperlink.

As described above with regard to card location, media coding can provide the basis for accurate lateral and longitudinal matching and motion tracking of the media coding itself, and the printer may also send this match to the netpage server on the netpage identifier side. You can report it. The Netpage server can record this registration information as a two-dimensional offset that corrects for all deviations between nominal and actual matches, thus recording all digital ink captured by the card prior to interpretation. I can correct it.

Netpage  Identifier ( Netpage Identity )

The card can be coded so that the printer can determine the card's unique 96-bit netpage identifier. This allows the printer to report the card's netpage identifier for recording by the netpage server (combining printed graphics and input descriptions with the identifier).

The card may be coded such that the printer determines the card's unique netpage identifier from either side of the card. This gives printer designers the flexibility to read netpage identifiers from the most convenient card side.

The card can be coded to determine whether the printer will make the card an authenticated netpage card, thereby preventing the printer from executing a Netpage association step for an unauthorized card, effectively It does not work. This prevents the use of a valid card with the same netpage identifier due to a forged card.

The card can be coded to cause the printer to determine both the netpage identifier and the unique digital signature associated with the identifier. This prevents the forgery of using the digital signature verification mechanism in place before, for the purpose of controlling interaction with the Netpage media.

Netpage  Interaction( Netpage Interactivity )

Practically all of the front side of the card is coded with a netpage tag allowing the netpage detection terminal to interact with the card following printing. This allows the printer to print interactive netpage content without having to include tag printing capabilities. If the back side of the card is blank and printable, then substantially the entire side of the card is coded with netpage tags to cause the netpage sensing terminal to interact with the card following printing. This allows the printer to print interactive netpage content without having to include tag printing capabilities.

The back side of the card is coded with netpage tags to cause the netpage detection terminal to interact with the card. This allows interactive netpage content to be preprinted on the back of the card.

cryptogram( CRYPTOGRAPHY )

background( Background )

Blank media designed to be used in the preferred embodiment are precoded to meet various requirements, assisting in motion detection and netpage interaction and also preventing forgery.

The next section describes an authentication mechanism that can detect a target medium and distribute the counterfeit or uncoded target medium. Forged or uncoded media are referred to below as invalid media.

A number of requirements are derived from the need to protect against invalid media. Only genuine media is guaranteed to maximize print quality because color management is closely related to the actual media characteristics. Maximizing print quality can be ensured by excluding invalid media. On the contrary, print quality cannot be guaranteed as an invalid medium.

Netpage interaction is a fundamental feature of the print media in the preferred embodiment. Through the exclusion of invalid media, netpage interactions can function properly, i.e., a valid and unique netpage tag pattern can always be provided.

Media identification and authentication can also be used to extinguish the expiration date of a medium, for example for quality control purposes.

Once printed, the medium may serve as a secure token that provides privileged media support for access to information associated with the medium. For example, the medium would be suitable for the output of the picture and moreover the medium could serve as a token to grant access to the support of the picture and the corresponding digital image.

In addition, these organizations described herein can be used as an authentication medium as a security token.

Media identifier  And digital signatures ( Media Identifier and Digital Signatures )

In a preferred embodiment, the media coding includes a unique media identifier and two digital signatures associated with the media identifier. Hereinafter, the digital signature will be described in detail. The media identifier and digital signature are coded in both the netpage tag pattern and, if any, the data track, as described below.

The short digital signature is a digital signature associated with a media identifier and is known only to the authentication server. For example, the short signature may be a random number, which is explicitly recorded by the authentication server and indexed by the media identifier. Therefore, the short digital signature is authenticated by the server.

Long digital signatures are the public-key digital signatures of media identifiers. The media identifier is optionally padded with random numbers before being signed. The public key digital signature can be authenticated without reference to the authentication server, as long as the authenticator has a public key that is valid and associated with the media identifier. If padding is required, it can be authenticated with reference to the server.

In addition, the short signature and the long signature may be used in combination.

If the precoded target medium is replicated correctly, the copy itself cannot be identified as a counterfeit. However, by tracking the merchandise and the movement and / or use of the media identifier, the authentication server can detect duplicate use of the same media identifier and eliminate it as a generally fraudulent use. Counterfeiters cannot assume that the original (ie, invisible) media identifier is a valid digital signature, so there is no penalty for users of valid media, excluding duplicates.

Authentication during printing ( Authentication during Printing )

The M-print print terminal is set to obtain a media identifier and one or both digital signatures before printing, during printing, or after printing is completed. The M-print terminal, if present, obtains this information from the netpage tag pattern and / or datatrack.

The M-print terminal may use the information to authenticate the medium. The M-print terminal may query the authentication server to authenticate the media identifier and the short signature, or locally authenticate the media identifier and the long signature, if they have the appropriate public key in advance.

The M-print terminal may first collide with the media identifier in a range to obtain a public key associated with the media identifier's range, thereby storing the index indexed public key for future use. have. The M-print terminal may flush the stored information to the reclaimed space at any time, for example based on at least recent or at least frequent usage history. The M-print terminal can obtain the public key from the authentication server itself or from any other trusted source.

If the M-print terminal cannot authenticate before or during printing, printing can be stopped to prevent the use of the medium. If media authentication is only possible after printing, then feedback can be provided to the user indicating that the media has been forged.

If the M-print terminal cannot obtain coded information from the medium at all, printing may be interrupted and / or signal the user that the medium is invalid.

If the printed content source is network-based, then the M-print terminal is not trusted and then the server providing the printed content is a security token that delivers the content in media authentication, i.e. the media itself allows printing. It can predicate that it can work.

Netpage  Authentication during interaction ( Authentication during Netpage Interaction )

When a netpage pointing terminal (such as an M-print terminal incorporating a netpage pointer) is tapped (or swept) into a netpage functional medium such as a printed M-print medium, the netpage pointing The terminal is configured to obtain one or both digital signals from the media identifier and the netpage tag pattern.

The terminal can thus authenticate and need to be able to authenticate the medium, using the medium described above.

More importantly, it is used to interact with valid media by verifying the Netpage server and providing a copy of the media identifier to the server and one or both digital signatures (or fragments thereof). This allows the server to authenticate the medium and also eliminate attempts to interact with the invalid medium. For example, the server can exclude attempts to download digital images associated with printed photos, thereby preventing access to fraudulent photographic images based solely on speculation as valid media identifiers.

Once printed, the medium may serve as a secure token that provides privileged media support for access to information associated with the medium. For example, the medium would be suitable for the output of the picture and moreover the medium could serve as a token to grant access to the support of the picture and the corresponding digital image.

In addition, such an apparatus described herein can be used to authenticate the medium with a secure token.

mobile Netpage  Security of M-Prints in the Environment ( Security in  M- Print in Mobile Netpage Contexts )

As mentioned above, the certificate is verified by verification of the correspondence between the data and the signature of the data. The more difficult the signature forgery, the greater the reliability of signature-based authentication.

The Netpage ID is unique and thereby provides the basis for the signature. If online authentication access is assumed, the signature may simply be a random number associated with the identity of the authentication database accessible by the trust online authenticator. Random numbers can be generated in any suitable way, such as through deterministic (pseudo-random) algorithms, or through stochastic physical processes. Keyed hashes or encrypted hashes are preferred because they do not require additional space in the authentication database. However, random signatures of the same length as the lock signature are more secure than the lock signature because they are not affected by key attacks. Similarly, relatively short random signatures provide the same security as relatively long lock signatures.

In a limited case, no signature is actually required, since the simple existence of an ID in the database implies authentication. However, using a signature restricts the forger from actually forging the item.

In order to prevent forgery of signatures with invisible IDs, signatures should be large enough to allow exhaustive retrieval through persistent repetitive access to online authenticators. If a key is used without randomization in signature generation, its length must also be long enough to prevent the forger from estimating the key from a known pair of ID signatures. Hundreds of bits of signatures are considered secure, depending on whether they are generated using a private or secret key.

Including a reasonably secure random signature in a tag (or local tag group) is effective, especially if the length of the ID is reduced so that more space is provided for the signature, the tag will contain the signature obtained with the secure ID. to be. To aid in secure ID-derived signatures, you can instead distribute a fragment of the signature across multiple tags. If each fragment ID is verified as quarantined, the goal of assisting authentication without enlarging the clock of the sensing terminal is achieved. Nevertheless, the security of the signature is derived from the full length of the signature rather than the length of the fragment, since it is not possible to predict in which fragment the verification of the random selection of the counterfeit user will be made. The trust authenticator can always verify the fragment, since the authenticator has access to the key and / or the entire stored signature so that fragment verification is always possible when online access to the trust authenticator is valid.

Fragment verification requires the prevention of violent attacks on individual fragments, otherwise the counterfeit may attack each fragment in turn to determine the full signature. Violent attacks can be prevented by throttling the authenticator on a per-identity basis. However, if the fragment is short, extreme throttling is required. As an alternative to authenticator throttling, the authenticator may instead enforce a limit on the number of verification requests to respond to a given number of fragments. Even if the threshold is very small, a normal user is unlikely to consume the limit for a given fragment because there are many valid fragments and the actual fragment selected by the user may vary. Nevertheless, one limit may be practical. More generally, the threshold should be proportional to the fragment size, i.e. the smaller the fragment, the smaller the threshold should be. Thus, the user's experience is somewhat unchanged for the fragment size. Enforcing throttling and fragment verification limits means serialization of the request to the authenticator. The fractional validation limit that needs to be added only in the case of a verification failure, that is, an infinite number of successful verifications can occur before the first failure. Moreover, enforcement of the limit of fragment verification is necessary for the authenticator to maintain per-fragment satisfied verification requests.

Violent attacks are also prevented by concatenating random signatures coded in tags. Random signatures are regarded as a safeguard for fragments, while fragments are also viewed as a simple extension of the length of random signatures, thereby enhancing security. The fragment verification limit can be verified on the condition of denial of service attack, where the attacker inevitably needs to limit the invalid verification request to prevent further verification of the question ID. Will be exceeded. Thus, when the accompanying random signature is correct, it can be prevented only by enforcing the fragment verification limit for fragments.

Fragmentation can be safer by requiring minimal fragmentation at the same time.

Fragment verification requires a fragment identifier. Fragments can be more economically identified as two-dimensional coordinates of their tags, either explicitly numbered or in a modulo that repeats the signature across the tiling of consecutive tags.

Moreover, it is vulnerable by limiting the length of the ID itself. Ideally, the ID length should be at least several hundred bits. It is 96 bits or less in the coding scheme of the netpage surface. To overcome this, the ID may be padded. To be effective padding it must vary, i.e. from one ID to the next. Ideally, padding should be stored in the authentication database, which is indexed simply as a random number, as an ID. If padding is deterministically generated from the ID, it is worthless.

Offline authentication of the private key signature requires the use of a trust offline authentication terminal. QA chip (the contents of US patent including 6,566,858 (registration no. All applications filed on July 8, 2010 provide the basis of such a terminal, although capacity is limited. The QA chip can be programmed to use the private key securely stored in internal memory to verify the signature. However, in this scenario, assisting padding by ID is impractical and even impractical to assist more than a few private keys. Moreover, QA chips programmed in this way are subject to a chosen-message attack. Due to these limitations, the application of a QA-chip-based trust offline authentication terminal is limited to niche applications.

Usually, although security is required for all individual trust offline authentication terminals, creators of security items do not attempt to assign their secret signature keys to these terminals, and this tendency also implies the applicability of the terminals. Application in the field is important, but it is limited to the application in a specific field.

In contrast, offline authentication of a public key signature (ie, generated using the corresponding private key) is very practical. Offline authentication terminals using a public key are often designed to be able to accept any number of public keys and, in the event of a collision with an ID without a corresponding public signature key, to reactivate the desired additional public key through a temporary online connection. Can be. Untrusted offline authentication is attractive to most secure item creators because exclusive control of their private signature keys can be maintained.

The disadvantage of off-line authentication for public key signatures is that the entire signature must be secured from coding, which counters the usual need to support authentication with a minimal clock. The corresponding advantage of off-line authentication for public key signatures is that access to ID padding is no longer required. Both the ID and its padding are generated by decrypting the signature using the public signature key, so padding is ignored. Because it can be. Forgers do not benefit from the fact that padding is ignored during offline authentication, because padding is not ignored during online authentication.

The acquisition of the entire distributed signature is not particularly burdensome. A hand-held sensing terminal can quickly acquire all fragments of the signature by random or linear swipe across the coded surface. The sensing terminal can be easily programmed to acquire a full set of fragments and signal the user when authentication is complete. The terminal can be programmed to only perform authentication when the tag indicates the presence of a signature.

The need for swiping is of little concern in terms of authenticating print media prior to or during printing in a preferred embodiment of a mobile terminal incorporating a printer. In a preferred form, the print media is inserted in the media feed path for printing. In both cases during this insertion or subsequently while the print media is being transported by the drive mechanism of the terminal, the sensing terminal can read a series of tags sufficient to obtain all the required fragments of the signature.

The use of authentication has been described with reference to netpage tags, but similar principles can be applied to the linear encoding scheme (or any other encoding scheme) used to encode data on preprinted print media.

It should be noted that the public key signature can be authenticated online through all fragments in the same way as any signature, whether randomly generated or using a secret key. The trust online authenticator can use a private key and ID padding to generate a signature upon request or to explicitly store the signature in the authentication database. The latter approach eliminates the need for storage of ID padding.

Signature-based authentication can also be used with appropriate fragment-based authentication when online access to the trust authenticator is valid.

Table 13 summarizes the possible signature schemes using data structures coded with the preferred coding scheme. It will be appreciated that this limitation does not apply to all coding schemes that may be used in the present invention.

Algorithm of the cipher ( Cryptographic Algorithms )

If the public key signature is authenticated offline, the user's authentication terminal typically does not have access to the padding used when the signature was originally created. Therefore, the signature must be decrypted at the signature verification stage, so that the authentication terminal can compare the ID in the signature with the ID obtained from the tag. This eliminates the use of algorithms that decrypt signatures and do not perform the signature verification phase, which includes the January 27, 2000, Department of Commerce / National Institute of Standards and Technology.

It is described in.

RSA provides a shared key digital signature algorithm suitable for decrypting signatures. RSA is based on the National Standards Institute's ANSI X9.31 digital signature standard and the Digital Signatures Using Reversible Public Key Cryptography of the Financial Services Industry of September 8, 1998. (rDSA). If padding is not used, a shared key signature algorithm can be used.

In a preferred netpage surface coding scheme, the ID is 96 bits or less in length. The ID is padded 160 bits before being signed.

Ideal padding is created by using a true random process, such as a quantum process, or by extracting randomness from a random event. For more information on this, see the second edition of Applied Cryptography, by John Wiley & Sons, Schneier, B., 1996.

In a preferred netpage surface coding scheme, the random or secret signature is 36 bits or less in length. It is also ideally generated using an intrinsic random processor. If a relatively long random signature is required, the ID length in surface coding can be reduced to provide additional space for signatures.

certification( Authentication )

Each of the object IDs has a signature. In a limited space within the preferred tag structure, it is not practical to include the entire cryptographic signature within a tag since signature fragments are spread across multiple tags. Relatively small random or secret signatures may be included in the tag.

To avoid vulnerabilities due to the limited length of the target ID, the target ID is padded, ideally using random numbers. Padding is stored in the authentication database indexed by subject ID. The authentication database may be managed by a manufacturer or by a trusted third party authenticator.

Each tag contains a signature fragment and each fragment (or subset of fragments) can be verified in isolation against the target ID. Nevertheless, the security of the signature is derived from the total length of the signature rather than the length of the single plate, because the forger cannot predict which fragments the user will randomly choose to verify.

 Fragment verification requires fragment identification. Fragments can be identified by the two-dimensional coordinates of those tags, either explicitly numbered or in the form of repeating the signature across successive tiling of tags.

It should be noted that the trust authenticator can always perform fragment verification, so fragment verification is always possible if online access to the trust authenticator is valid.

Offline public key based authentication ( Off - line Public - Key - Based Authentication )

The offline authentication terminal uses a public key signature. The authentication terminal accepts a number of public keys. Optionally, the terminal, when there is no corresponding public key signature and collides with the subject ID, may reactivate the desired additional public key via a temporary online connection.

For offline authentication, the full signature is required. The authentication terminal is swiped over the tagged surface to read a number of tags. In this way, not only the object ID but also a plurality of signature fragments and their positions are obtained. A signature is then generated from these signature fragments. The public key is retrieved from the scanning terminal using the target ID. The signature is then decrypted using the public key and given a target ID and padding. If the subject ID obtained from the signature matches the subject ID in the tag, the subject is considered authenticated.

In addition, the offline authentication method can be used online, with a trust authenticator acting as an authenticator.

Public key-based authentication online On - line Public - Key - Based Authentication )

The online authentication terminal verifies the authenticity of the subject using the trust authenticator. For online authentication, a single tag is all that is required for authentication. The authentication terminal scans the object to obtain one or more tags. This obtains not only the object ID but also at least one signature fragment and its location. The number of fragments is generated from fragment positions. The appropriate trust authenticator is retrieved by subject ID. The subject ID, signature fragment, and fragment number are sent to the trust authenticator.

The trust authenticator receives the data and derives the signature from the authentication database as the subject ID. The signature at this time is compared with the provided fragment and the authentication result is reported to the user.

Online secret-based authentication ( On - line Secret - Based Authentication )

Alternatively or additionally, if a random signature or secret signature is included in each tag (or tag group), this can be verified by reference to a copy of the secret signature accessible to the trust authenticator. The database setup then includes a step of assigning a secret to each subject, storing it in the authentication database, and indexing it by subject ID.

The authentication device scans the object to obtain one or more tags. From this, the secret as well as the object ID is obtained. A suitable trusted authenticator is retrieved by the object ID.

The trusted authenticator receives the data and retrieves the secret from the authentication database by the object ID. This secret is compared to the supplied secret and the authentication result is reported to the user.

Secret-based authentication can be used with the online fragment-based authentication described in more detail above.

Netpage  Clicker ( NETPAGE CLICKER )

140 and 141 show another embodiment of the present invention. In this case, the mobile terminal includes a netpage clicker module 162. This embodiment includes a printer and includes a dual optical path device for sensing coded data from a medium external to the mobile terminal, as well as coded data preprinted on the medium passing through the mobile terminal for printing. use.

In a preferred embodiment the netpage clicker forms part of a dual optical netpage sensing device. The first path is used in the netpage clicker and the second path operates to read coded data from the card entering the mobile communication terminal for printing. As described below, the data coded on the card is read to ensure that the card is of the correct type and quality to enable printing.

The netpage clicker includes a non-marking pen nib 340 that emerges from the top of the mobile communication terminal. The nib 340 is slidably mounted to be selectively movable between the retracted position and the position extruded by manual operation of the slider 342. Slider 342 is biased outward from the mobile communication terminal and includes a ratchet mechanism (not shown) for holding the nib 340 in the extended position. When the user presses the slider 342 to retract the nib 340, the slider 342 disengages the ratchet mechanism and allows the nib 340 to return to the retracted position. One end of the nib 340 is in contact with a switch that is operatively connected to a circuit on the PCB.

Moving from one end of the first optical path to the other end, a first infrared LED 344 is mounted to direct infrared light through the aperture from the mobile terminal to illuminate an adjacent surface (not shown). Light reflected from the surface passes through an infrared filter 348, which enhances the signal to the noise ratio of the reflected light by removing most of the non-ultraviolet ambient light. This reflected light is concentrated through the pair of lenses 350 and impinges on the plate beam splitter 352. It will be appreciated that this beam splitter 352 may include one or more thin film light coatings to improve its performance.

Much of the light is directed down on the image sensor 346 which is deflected down by the plate separator and mounted on the PCB. In a preferred embodiment this image sensor 346 takes the form of a Jupiter image sensor and a processor described in detail below. It will be appreciated that commercially available CCD and CMOS image sensors are also suitable.

The specific position of the nib and the orientation and position of the first optical path in the casing allow the user to interact with the netpage interactive documents described elsewhere in the detailed description. Such netpage documents may include media printed by the mobile terminal itself, as well as other media such as pages preprinted in books, magazines, newspapers, and the like.

The second light path, starting with the second infrared LED 354, is mounted to shine light onto the surface of the card 226 when inserted into the mobile communication terminal for printing. This light is reflected from the card 226 and redirected along the light path by the first turning mirror 356 and the second turning mirror 358. This light then passes through the aperture 359 and the beam splitter 352 to reach the image sensor 346.

The mobile terminal is configured such that both the LEDs 344 and 354 are off when the card is not printed and the nib is not used to sense data coded on the outer surface. However, when the pen tip is pushed out and pressed onto the surface with enough force to close the switch, the LED 344 is illuminated and the image sensor 346 starts capturing images.

Although non-marking nibs have been described, marking nibs such as ballpoint pens or felt-tip pens may also be used. Where marking nibs are used, it is particularly desirable to provide a shrinkage mechanism that allows the nibs to selectively enter the casing. Optionally the nib can be fixed (ie no shrinkage mechanism is provided).

In other embodiments, the switch may simply be omitted (and only when the terminal is placed in a continuous, preferably capture mode) or replaced by some other form of pressure sensor, such as a piezoelectric or semiconductor based transducer. have. In one form, a multi-level or continuous pressure sensor is used, which makes it possible to capture the actual force of the nib against the writing surface during writing. This information may be included with the location information including the digital ink generated by the terminal, which may be used in the manner described in detail in the various applications related to this assignee's cross-referenced netpage. However, this is an optional feature.

It will be appreciated that in other embodiments, a simple netpage sensing device may also be included in a mobile terminal that does not incorporate a printer. Although the mobile terminal has a printer in this context, FIGS. 85 to 87 show examples of such clickers. 85 to 87, it will be appreciated that the netpage clicker is wholly related to sensing coded data from external netpage documents.

In another embodiment, to change the path of light through the first or second optical path, one or more of the redirecting mirrors are replaced with one or more prisms that depend on boundary reflective or silvered (or half silvered) surfaces. Can be. It is also possible to omit one of the first or second optical paths by removing the corresponding function provided by the first or second optical paths.

Image sensor and associated processing circuitry ( IMAGE SENSOR AND ASSOCIATED PROCESSING CIRCUITRY )

In a preferred embodiment, the netpage sensor is a monolithic integrated circuit comprising an image sensor, an analog-to-digital converter, an image processor and an interface, which are adapted to operate within a system comprising a host processor. It is composed. Applicant coded this monolithic integrated circuit as "Jupiter." The image sensor and ADC are coded "Ganymede" and the image processor and interface are coded "Callisto".

Environment

Callisto interfaces not only to image sensors via parallel interfaces, but also to external devices such as microprocessors via serial interfaces. Captured image data is transferred from the image sensor to Callisto via a parallel data interface. The processed image data is transferred to the external device via the serial interface. Callisto's registers are set via the external serial interface.

function

The callisto image processing core receives image data from an image sensor and transfers the processed or raw data to an external device using a serial data interface. The rate at which data is delivered to the external device is separated from what data read rate is forced by the image sensor.

The image sensor data rate and image data rate on the serial interface are disconnected by using an internal RAM-based frame store. Image data from the sensor is written into the frame store at a rate that meets image sensor reading requirements. Within this frame store, data is read once and transmitted over the serial interface at that speed, whatever speed is required by the device at the other end of the interface.

Callisto may optionally perform some image processing on images stored in the frame store, as indicated by user preferences. The user may choose to bypass image processing to gain access to the raw image. Subsampled images are stored in a buffer, but fully processed images are not persistently stored in Callisto. Instead, the fully processed images are sent immediately via the serial interface. Callisto provides several image processing related functions.

Subsampling, local dynamic range expansion and thresholding are typically used with dynamic range expansion performed on subsampled images and thresholding performed on subsampled, range expanded images. Dynamic range expansion and thresholding may be performed together as a single operation and may only be performed on subsampled images. However, subsampling may be performed without dynamic range expansion and thresholding. Information retrieval of sub-pixel values and image area reading are standalone functions.

Alternative tag sensor devices ( ALTERNATIVE TAG SENSOR ARRANGEMENTS )

Now, a number of special alternative optical systems for performing the detection of netpage tags using the mobile terminal will be described with reference to FIGS. 144-150.

Basic Two-Dimensional Tag Image Sensor : FIG. 144 illustrates a basic configuration of a two-dimensional tag sensor for detecting tags on a pretagged print medium before printing. Tag sensors typically synchronize with image sensor 664, focus lens 666, aperture 668 to ensure proper depth of field, ultraviolet filter 670 to remove ambient light, and image capture. ultraviolet light source 669 that is strobed in sync. The tag sensor in the figure represents an image of the surface of a blank pre-tagged to the left. The ultraviolet filter is not included in the configuration, provided that the ambient light can be properly removed from the printing path. Image capture can be initiated by detection of print media in the print path.

Dual-purpose 2D tag image sensor : If the netpage printer is integrated into a device that already includes a netpage tag sensor such as a pen, a mobile terminal such as a PDA or a telephone, the tagged surfaces designed by the user and provided to the printer It may be convenient to multiplex the operation of a tag sensor that senses between tagged objects. In the following, these two imaging modes are called external and internal imaging respectively.

145 illustrates a multiplexed tag sensor with dual light paths and a single image sensor 664 as one possible configuration. This tag sensor is shown to image the outer tagged surface 671 and the surface of the pre-tagged object print medium 672.

The inner light path includes a first mirror 673 that directs it in the opposite direction of the outer light path and a second mirror 674 (shown in plan view) that causes it to image the print medium 672. In FIG. 145, the second mirror 674 reflects the optical axis at right angles to the print medium, that is, as shown in FIG. 144, the mirror is literally mounted at 45 degrees to the surface of the print medium.

Each light path integrates its own aperture and lens devices 675. The focal length of each lens can be selected according to its corresponding light path. Since shallower depths of field are possible, larger holes in the inner light path may potentially be used than in the outer light path.

Each light path has its own ultraviolet light source. When the first illumination source 677 flashes synchronously with the image sensor 664, the image sensor captures an image of the tagged surface 671 indicated by the user. When the second illumination source 676 flashes, the image sensor captures an image of the pre-tagged object print medium 672. External image capture can be initiated by a user-initiated "pen down" or "click". Internal image capture can be initiated by detection of print media in the print path.

Since both light paths impinge on the image sensor at an angle, some loss of focus may occur unless corrected by the lenses. This induced perspective distortion can be automatically handled by the image processing and decoding algorithms.

Multiplexed Tag Sensor with Beam Separator : FIG. 146 shows a modification of the multiplexed tag sensor of FIG. 145, which has a beam-separator 678 separating the optical path. This beam-separator 678 is shown downstream of the aperture, but it may be disposed upstream of the focus lens if the two light paths have substantially different lengths.

Multiplexed tag sensor with beam splitter and in-line illumination : FIG. 147 shows a modification of the multiplexed tag sensor of FIG. 146, which has ultraviolet light projected in a line with the imaging path through the beam-separator 678 have. The IR filter 679 ideally has an anti-reflective coating that minimizes the reflection of the outgoing light. Optionally, this IR filter 679 may be disposed upstream of the beamsplitter to entirely avoid the problem of reflection.

With a shared light source, selectively turning on one or the other light source may no longer be used to select one or another imaging path. Instead, a shutter 680 is introduced into the external imaging path for this purpose. If a non-reflective print path is provided in the absence of print media, there is no need to introduce a shutter into the internal imaging path.

The external imaging shutter 680 may be electronically controlled or mechanically controlled. The mechanical shutter may be spring-loaded to open naturally, and the print path may include a lever that engages with the print media and is mechanically coupled to the shutter to close the shutter when the media is present. Conversely, this shutter can be spring-loaded so that it closes naturally, and the “nib” that the user presses on the tagged surface to begin external imaging is mechanically coupled to the shutter to open the shutter when the nib is pressed against the surface. Can be. The electromechanical shutter may consist of a mirror mechanically coupled to a pivoting barrier or electromagnet. The electronic shutter may consist of a liquid crystal element that can be switched electronically between a transparent state and an opaque state, or a digital micromirror element that can be switched between a reflecting or deflecting state. Although shown as a turning barrier in FIG. 147, this shutter is mounted at a position that normally reflects in the optical path when using the mirror rather than the barrier.

If there is insufficient headspace to accommodate the entirety of the viewing cone on the print medium, two mirrors can be used to aim and re-expand the viewing cone. The first mirror may be concave in a direction perpendicular to the surface of the print medium to aim the viewing cone, and the second mirror may be convex in the same direction to re-expand the viewing cone. The second IR illumination source may similarly have a lens that aims the illumination cone in the same direction. As shown in FIG. 148, the second mirror can also be inclined at less than 45 degrees to the surface of the print medium, and the first mirror can be similarly inclined to achieve top-leveling.

Tilted mirror to reduce head space : The result of ambient light entering the tag sensor through the external light path during imaging of the print media is due to the exposure time, the response of the IR filter, and the configuration of the external light path relative to its host device. Function. For example, if an external light path exits the top of the host device, it may encounter a bright light source, such as the sun, within its field of view.

If ambient light is a problem, the external light path may be closed while the print medium is imaged. Alternatively, as shown in FIGS. 149 and 150, a pivoting mirror can be used to multiplex the light path between external and internal imaging.

In the external imaging mode, multiplexed tag sensor with pivoting mirror : FIG. 149 shows a tag sensor with pivoting mirror 681 disposed for external imaging, FIG. 150 with a mirror positioned for internal imaging. Represents one tag sensor.

This mirror can be controlled electronically or mechanically. The mechanical mirror may be spring-loaded to naturally be in the external imaging position and the print path may include a lever that engages with the print medium and is mechanically coupled to the mirror to pivot the mirror to the internal imaging position when the print medium is present. Can be. Conversely, this mirror may be spring-loaded so that it is naturally in the internal imaging position, and the “nib” that the user presses on the tagged surface to begin external imaging is mirrored to the external imaging position when the nib is pressed against the surface. It can be mechanically coupled to the mirror to pivot it. This mirror can also be coupled to the electromagnet, which is activated to achieve internal or external imaging. The electronic mirror may consist of a digital micromirror element that can be switched between internal imaging and external imaging reflection states.

The invention may also be embodied in a number of other form factors, one of which is the PDA shown in FIGS. 151-160. The functions of mobile phone means with convergence between PDAs and mobile phones are increasing, however, still PDAs are sufficiently different from mobile phones, so that they generally specify different sets of requirements. For example, mobile phones are small enough to be carried in a user's pocket and are primarily used for voice communications and short sentence messages. PDA-style functionality (such as contact and assignment handling) can be provided, but small screen sizes (due to small form factors) and limited control interface options (due to isometric size issues) can be achieved with large screens and (often) touch screen inputs. It makes mobile phones less convenient than large PDAs with features.

The present invention can be incorporated into a PDA (300). This PDA 300 shares a number of features and components with the mobile phone described above, and the shared components are denoted by the same reference numerals. A notable difference between this PDA 300 and the mobile phone is that the print cartridge 148 (as best shown in FIGS. 154 and 158) is near the top of the PDA, rather than vertically along one side as in a mobile phone. Is placed horizontally on the Optionally, it may have a wider print width to take advantage of the additional width of the PDA (and the overall space gain provided by the size of the PDA).

Referring to FIG. 160, this PDA 300 also differs from a cell phone in that it provides a replaceable casette 302 that supports a pile 304 of print media. The print media may be the same size and shape as described for a mobile phone, or may be larger or smaller in different widths or materials, or may have other coded data or have preprinted advertising material. However, this description will assume that the medium is as described for the mobile phone embodiment.

As best shown in FIG. 160, PDA 300 includes a bottom molding 306, a spring 308, a pile 304 of 20 print media (in a preferred embodiment) and a top molding 310. . The bottom molding 306 includes clip formations 312 that snap into the complementary holes 314 formed in the top molding 310. The spring 308 includes finger portions 316 that engage the bottom of the bottom molding 306 and a support region 318 that engages the media stack 304. The top molding 310 also includes an exit hole 319 to allow the print media to exit for printing.

This PDA has a larger display 138 than a mobile phone and can use any suitable display technology such as OLED or TFT. It is particularly desirable for the PDA to incorporate a touch-sensitive display (or display overlay) that allows the user to interact with the icons and other information shown on the display.

155 and 156, the netpage sensor in the PDA 300 is a modified version of the device described with respect to FIG. 145, and like numbers have been used to indicate corresponding features. This particular device allows the mirrors 673 and 674 shown in FIG. 145 to be removed. When reading tags from the print media in the small box, images are captured from the print media on top of the dummy to be printed next. Tags on each subsequent print medium are read out by exposure to the preceding print medium being removed from the cartridge for printing.

When a picture is captured and printed using a netpage digital camera, the camera also continuously stores the picture image on a network server. The printed picture can then be used as a token for retrieving the picture image as a netpage is tagged.

Smartphones with a camera function can be viewed as a camera with a built-in wireless network connection. When the smartphone with this camera function incorporates a netpage printer as described above, it becomes a netpage camera.

When a smartphone with a camera function also integrates a netpage printer and a pen, as described above, the pointer or pen can be used to point to the printed netpage photo to request a printed copy of the photo. . This can be done by sending at least an identifier of the printed document to a netpage server. This information alone will be enough to make the photo searchable for display or printing. However, in a preferred embodiment, the identifier is sent along at least one location of the pen / clicker as determined.

The mobile phone or smartphone netpage camera can take any of the above embodiments incorporating a mobile phone module that includes a printer and a camera.

Universal pen UNIVERSAL PEN )

Other embodiments of the invention incorporate a stylus with an inkjet printhead nib.

In the first embodiment shown in Figures 161 to 178, the mobile terminal includes a retractable stylus 1000 that includes an elongated body portion 1002. This body portion 1002 incorporates a recess 1004 that supports the coil spring 1006. A hump 1008 is formed on one side of the body part 1002, and a stop 1010 is formed on the other side of the body part 1002.

One end of the body portion 1002 includes ink galleries to which the nib cap 1152 is attached and communicates the ink to a printhead 1120 attached to the free end of the cap 1126. Preferably this printhead is an inkjet type printhead and more preferably a microelectromechanical system (MEMS) based inkjet as described in detail elsewhere herein. These preferred MEMS based inkjets use mechanical actuators to eject ink, rather than heating the ink, as is currently used by most inkjet printers currently available. Since such MEMS-based inkjets have lower power consumption than such printers, it is attractive for use in portable devices where the available power is limited. Alternatively, thermal inkjet printers as described elsewhere herein may also be used.

Whatever type of inkjet ejection technique is used, in a preferred form the ink ejection devices (e.g., nozzles) are arranged in partial spirals 1370-1380, as best shown in Figures 183 and 184. Can be. This spiral arrangement produces cross-patterned ink dots that are more evenly spaced and more fully cover the width of the pen, regardless of the orientation of the printhead relative to the direction of movement of the pen, resulting in cross-referenced patent USSSN 10 / 309,185 (registered) And a more satisfactory stroke than the linear device disclosed in No. UP08US, filed Jan. 1, 2002. This linear arrangement is easy to produce strokes with visible stripes when the direction of movement of the pen is substantially parallel to any of its radial lines of ink jetting devices, whereas in the spiral arrangement There are always lines of ink jetting devices perpendicular to the direction of motion across the entire width of the device.

Since ink ejection devices located along the portions of the spirals substantially parallel to the direction of movement can be prevented from ejecting ink, streaks due to uneven density can be further suppressed if the direction of movement is known. The spiral arrangement may include a larger number of ink jetting devices in the same area as the linear arrangement, which leads to better silicon usage and greater fill density, and the spiral arrangement may be applied to selected inks, such as black and cyan. For the two inks, additional ink jetting devices close to the axis of the printhead are allowed, which allow a much higher fill density.

Although the preferred form of the invention uses rows of ink ejection devices arranged in such a spiral, the stylus printhead 1120 will be described with reference to other embodiments shown in FIGS. 169-178. Detailed drawings of the internal operation and assembly of the stylus are based on another embodiment of the present invention designed to operate with four colors CMYK, rather than the three colors CMY used by the preferred embodiment of the present invention. . As noted above, the specific number of colors, or the arrangement of nozzles in the printhead, is simply a matter of design change.

168 through 178, the printhead 1120 is adhered to the end cap 1126, but is mounted on a flexible printed circuit board (PCB) 1144 including control and power contacts 1146. do.

In order to allow a small amount of axial movement, an iron pen tip 1118 is mounted on the end cap 1126. The axial movement of this stylus tip 1118 (see FIG. 170) is controlled by integral arms 1148 extending laterally and axially away from the inner end of the stylus to bear against the site 1184. In use, pressing the stylus against a substrate causes the arms 1148 to bend and allow the stylus to enter. The stylus is preferably formed by injection molding a thermoplastic material, most preferably acetyl. This movement typically has a maximum amount of 0.5mm and provides some feedback to the user. In addition, the flexibility of the iron tip allows for adaptation to small amounts of roughness on the substrate surface. If desired, the iron tip may be fixed with virtually no allowable movement.

The nib cap 1152 extends above the end cap 1126, the printhead 1120, the PCB 1144, and the stylus tip 1118, and has a hole 1154 through which the free end 1156 of the stylus tip 1118 passes. It is provided. This hole 1154 is elliptical in shape and allows the printhead 1120 to eject ink through the hole beneath the iron tip.

The nib cap 1152 is secured in place by one or more resilient snap actuating arms 1158 formed integrally adjacent the edge thereof.

The control circuit for the inkjet actuator may be arranged at any suitable combination of positions within the device, such as in the print engine controller and / or the printhead itself. The on / off switch is preferably controlled so that ink is ejected only when the iron pen tip is pressed on the substrate. Pressing the stylus against the substrate generates a compressive force on the stylus tip. In this embodiment, it causes the movement of the stylus and the on / off switch can be activated by the movement, by sensing the compression force or by other means. Where the stylus is substantially fixed, there is no relative movement of the stylus tip relative to the rest of the pen.

The stylus is easiest to use in a particular orientation, but it is particularly important in use, and the stylus is configured such that the nib does not block the path of ink from the printhead to the paper in any orientation as shown in FIG.

168 shows the stylus against the paper in three different orientations, indicated by the numerals 1164, 1166 and 1168. FIG. The path of ink from the printhead is indicated by line 1170. The paper sheet 1164 represents the orientation with the stylus tip over the printhead, while the paper sheet 1166 represents the orientation with the stylus tip under the printhead. The paper sheet 1168 represents an orientation with an iron pen tip next to the printhead. As can be seen, the iron tip does not block the path of the ink to the paper in any orientation.

Print engine controllers and / or other circuitry associated with the stylus may be designed to adjust one or more features of the ink contained by the print head 1120. This can be the amount of ink contained, the width of the lines produced, the color of the ink contained (in the color cartridge) or any other attribute. Further information on this control is described in cross-referenced USSN 10 / 309,185 (registration no. UP08US, filed Jan. 12, 2002).

The printhead 1120 is mounted on the PCB 1144 and received in a recess in the end cap 1126. Not only this printhead but also the recesses are not circular to help in the correct orientation.

The iron tip 1118 is mounted in a slot 1184 of the nib cap 1152 and supported in place by the surface 1190 of the end cap 1126. The cantilever arms 1148 are supported against the site 1185 and bias the iron nib outwards. The front portion 1186 of the iron tip has a circular cross section but the rear portion 1188 has a flat surface 1191 that slides over the surface of the end cap 1126.

The iron tip includes slot 1181 extending obliquely along the flat surface 1191. In an embodiment of this invention, the printhead 1120 includes a rotary capper 1183. The capper can move between the first and second operating positions. In the first position, the ink jetting nozzles of the printhead are covered and preferably sealed to prevent drying of ink in the printhead and entry of foreign material or both. In the second position, the ink jetting nozzles of the printhead are not covered and the printhead can operate. The capper 1183 includes an arm 1185 that engages with the slot 1181. Thus, the capper 1183 rotates as the stylus tip enters and exits the printhead. When the iron tip is fully loaded and unloaded, the capper is in the first position and the capper is in the second position when the iron tip is retracted. This capper 1183 can incorporate an on / off switch for the printhead 1120 such that the printhead can only operate when the capper is in the second operating position. The slot has an oblique portion that opens and closes the capper, and furthermore has an axially extending portion where the movement of the capper with the iron tip movement does not occur at all.

The structure and arrangement of the printhead 1120 and capper 1183 are shown in FIGS. 170-178. This printhead 1120 is an assembly of four layers 1302, 1304, 1306 and 1308 of semiconductor material. Layer 1306 is a layer of electrically active semiconductor devices, including MEMS ink jetting devices 1310. Layer 1306 was constructed using standard semiconductor fabrication techniques. Layers 1302 and 1304 are electrically inert in the printhead and provide passages for supplying ink from the ink inlets 1182 to the ink ejection devices 1310. The layer 1308 is also electrically inert and forms a guard with holes 1320 above each ink ejection device 1310 to allow ink to eject from the printhead. The layers 1302, 1304 and 1308 need not be made of the same material as the layer 1306, or even a semiconductor, but by using the same material, problems at the material interface can be avoided. Also, by using semiconductor materials for all components, the entire assembly can be manufactured using semiconductor manufacturing techniques.

The printhead 1120 has three ink inlets 1182 and the ink ejection devices 1310 are arranged in twelve sets, each of which is approximately radial outward from the center 1300 of the printhead. Is laid out. Each fourth radial line of the ink ejection apparatuses 1310 is connected to the same ink inlet. Ink ejection devices connected to this ink injection port constitute a set of ink ejection devices. These ink ejecting devices 1310 are arranged zigzag on the sides of the radial line, which makes their radial distance closer. The twelve “lines” of the ink ejection devices 1310 are symmetrically arranged at intervals of 30 ° around the center 1300 of the printhead. It will be appreciated that the number of “lines” of the ink ejection devices 1310 may be more or less than twelve. Similarly, it may be more or less than four ink inlets 1182. Preferably, the number is the same as the number of lines for each ink inlet 1182. If a single ink is used, these ink inlets do not need to supply an equal number of "lines" of the ink ejection apparatuses. Also, different colors may have different numbers of nozzles. For example, black ink (if used) may have more nozzles than other colors.

The layer 1306 includes a tab 1311 provided with a plurality of sets of electrical control contacts 1312. Although briefly only four contacts are shown, it will be appreciated that depending on the number of different colored inks used and the degree of control desired for each individual ink ejection apparatus 1310 and other requirements, it may be more. The printhead is mounted on this PCB 1144 by adhering the tabs on the PCB 1144. The electrical contacts 1312 are engaged with corresponding contacts (not shown) on the PCB 1144. The layer 1306 includes a control circuit for each ink ejection apparatus which controls when the ink ejection apparatus is turned on. In general, however, all higher levels of control, such as what color inks to print and in what relative amounts, are performed outside of the printhead, preferably in the MoPEC integrated circuit. These high level controls are passed through the contacts 1312 to the printhead 1120. There is preferably at least one set of contacts 1312 for each set of ink ejection devices. However, each line or each individual ink ejecting device can be addressed. In the simplest, each set can be turned on or off simply by the control signals.

As shown in the top view of FIG. 177, the printhead 1120 has a substantially octagonal contour, with tabs 1314 and 1316 extending from opposite sides of the octagon. It will be noted that the tab 1314 is formed of all four layers 1302, 1304, 1306 and 1308, whereas the tab 1314 is formed of only the layers 1302, 1304 and 1306. This allows the PCB 1144 to adhere to the layer 1306 without extending over the top of the layer 1308. The octagonal shape of the tabs also helps to position the printhead in recess 1176 in the end cap 1126.

The capper 1183 is also preferably formed of a semiconductor such as the printhead and mounted on the printhead for rotation about the center 1300 of the printhead. Without the non-electrically active layers, the capper does not have to be the same material or semiconductor as the printhead. This capper can be rotated between an open position (see FIG. 177) and a closed position (see FIG. 178). The open position is shown with the closed position outlined in dashed lines in FIGS. 173 and 176. The capper 1183 has twelve radially extending holes 1318. These holes are sized and arranged so that all of the ink ejectors in the open position can freely eject ink through these holes. In the closed position the holes 1318 are over the material between the lines of the ink jetting devices, and the material of the capper between the holes 1318 is over the holes 1320 in the top layer 1308. As a result, ink cannot leak out of the printhead, and foreign matter that may cause clogging cannot enter the holes 1320 and the ink ejection devices.

The holes 1318 are preferably formed in the capper 1183 using standard semiconductor etching techniques. In the embodiment shown, each hole is equivalent to a series of overlapping cylindrical bores, the diameter of which is a function of the radial distance from the center 1300 of the capper. Optionally, the holes may be defined by two lines extending radially at small angles from one another. It will be appreciated that the holes need to increase in width as the radial distance increases as the outside of this capper moves more than the inside when rotated.

The capper has eight legs 1322 extending downward from the periphery of the lower surface 1326 and is substantially planar. These legs are spaced at equal intervals around the circumference and engage corresponding slots 1328 formed at the circumferential edge of the top surface 1333 of the top layer 1308. These slots are perpendicular to the rounded inner corners. In order to ensure that the capper rotates around the central axis 1300, the inner surface 1330 of the slots 1328 and the inner surface of the legs may be arc-shaped and may have their center at the center 1300 of the printhead. . However, this is not essential. In the embodiment shown, each face of the octagon has a slot 1328, but this is also not essential, for example, only the faces may have slots every other there. Symmetry of the legs 1322 and slots 1328 is also not essential.

Rotation of the capper is caused by engaging arms 1185 in angled slots 1181 in the iron tip. Rotation of the capper is eventually limited by the legs 1322 and slots 1328. In order to prevent damage to this capper, printhead or iron tip, the arm 1185 has a narrower portion 1334. If the iron tip is pressed too far, arm 1185 bends around the narrowed portion 1334. In addition, protective arms 1336 are provided on both sides of the arm 1185 and also serve to limit rotation. The recess 1176 into which the print head is inserted has an opening in which the protective arms are disposed. If for some reason the capper is rotated too much, the protective arms contact the sides of the opening and limit rotation before the legs 1322 touch the ends of the slots 1328.

It is preferred that the printhead only operates when the iron tip is pressed against the substrate. This stylus tip can cause the simple on / off switch to close as it moves into the pen. Optionally, the force sensor can measure the amount of force applied to the iron tip. In this respect the cantilever arms 1148 can be used directly as electrical force sensors. Optionally, a separate force sensor can be acted upon by the inner end of the iron tip. If a force sensor is used, it may simply be used to turn the printhead on or off, or to (electrically) control the speed of ink ejection so that, for example, a greater force causes a greater ejection speed. The sensed force can be used by the controller to control other attributes, such as the line width. Rotation of the capper may also cause the on / off switch to change state.

The printhead has other color ink ejection devices arranged in a radial direction, which causes a problem in supplying ink to the ejection devices when the other color ink ejection devices are arranged in a ƒƒ� arrangement. In a conventional printer, the ink ejection apparatuses are arranged in rows in parallel, so that all other inks could be supplied to each row from one or both ends of the row. In a radial arrangement this is not possible.

Four ink injection holes 1182 are provided on the bottom of the bottom layer 1302. These inlets are elliptical in shape on the back surface for about half the thickness of the layer 1302, and penetrate to the top surface leading to a circular hole 1340. The back of the layer 1302 also has four grooves 1342, 1344, 1346 and 1348 formed in the central portion. There are a plurality of holes extending through the layer 1302 from the grooves (see FIGS. 175 and 176). Since the lower surface of the lower layer 1302 seals against the end cap 1126, these grooves define a sealed passageway.

Ink holes 1356, 1358, 1360, and 1366 form ink in the ink dispensing grooves 1350, 1352, 1362, and 1368, which in turn distribute the ink to their respective rows 1370-1380 of the ink jetting devices. Supply.

FIG. 184 shows another alternative arrangement of the ink jetting apparatuses 1370 to 1381 corresponding to that shown in FIG. This is done in the same arrangement as shown in FIG. 183, but with a 0.5 mm radius compared to having a 0.8 mm radius in the arrangement of FIG. 183. This represents a more economical design when wider strokes are not needed. However, if the direction of movement is known, it should be noted that, even for stroke widths smaller than 0.5 mm, the arrangement of FIG. 183 can make a more satisfying stroke than the arrangement of FIG. This is because an ink jetting device which is farther away from the printhead axis than the radius of the touch but still within the boundaries of the touch can be used to contribute to the touch.

At the other end of the body portion 1002, flexible data, power, and ink conduits enter the stylus 1000. As best shown in FIG. 167, the conduit 1012 is based on a flex film 1014 with copper traces 1016 formed on one side thereof and a film 1018 formed on the other side. ).

The copper lines 1016 include data and power supply lines. The formed film 1018 forms three ink channels 1020. The conduit 1012 is folded back naturally like a snake to enable entry and exit of the body portion 1002 as described below.

The conduit 1012 remote from the body portion is connected to the cartridge 148 so that ink, data and power are supplied to the printhead in the stylus.

The stylus 1000 is mounted in the holder 1022 for an elastic sliding movement. The holder 1022 is an extension of the cradle 124 and includes an elongated hole 1024 through which the hump 1008 extends and a recess 1026 in which a stop 1010 is located. Not only the hole 1024 but also the recess 1026 extends along the holder 1022 so that the bumps and stops can slide in them as the stylus 1000 is pushed out and retracted, respectively.

A stylus retention mechanism 1028 is attached to a snap-fit retainer 1030 formed on the side of the holder 1022. The corresponding snap fit 1032 is generally circular in cross section and fits into the retainer 1030 during assembly. The retainer 1030 and snap fitting 1032 are configured such that the stylus holding mechanism 1028 is rotatable between an open position and a closed position, which will be described in more detail below. The first end of the stylus retaining mechanism 1028 includes a stop engagement portion 1034, while the other end is a molding that biases the stylus release button 1036 and the stylus holding mechanism 1028 to the closed position. Bias spring 1038 is included.

As best shown in FIG. 161, the tensile force of the coil spring 1006 grabs the stylus 1000 in the retracted position within the device. In this position, the tip of the stylus is protected from jams and collisions that may otherwise be encountered when not in use. The stop 1010 will be in a recess in the stop engagement 1034, which allows its end of the retention mechanism 1028 to rest relative to the outside of the device.

When the stylus is pushed out, the user places a finger or thumb on the hump 1008 and elastically slides the stylus 1000 against the tensile force of the coil spring 1006 to the extended position shown in FIG. 163. As the stylus 1000 moves toward the extruded position, the stop 1010 engages with an inclined surface (not shown) within the stop engagement 1034, which causes the stop engagement 1034. The bias spring 1038 resists bias and makes it pivot away from the body portion 1002.

As a result, the edge of the stop engagement portion 1034 clears the stop 1010, causing the stop engagement portion 1034 to bounce against the body portion 1002. The user then releases the hump 1008, causing the stylus 1000 to move in the contracting direction under tension of the coil spring 1006 until the stop 1010 engages with the stop engaging portion 1034. . This stylus is then held in the extended position while the user is using it for writing or drawing, as shown in FIG. 163.

To retract the stylus 1000, the user presses the stylus release button 1036, which causes the stylus holding mechanism 1028 to pivot with respect to the snap fitting 1032. In this case, the stop engaging portion 1034 is lifted up so that the stop 1010 is not caught. The stylus 1000 is then freely retracted under the tension of the coil spring 1006 to return to its original position shown in FIG. 161.

The conduit 1012 provides a compact path for supplying ink, data and power to the stylus, while still allowing the shrink mechanism to function.

In the second embodiment shown in FIGS. 179 to 181, like reference numerals denote features corresponding to those of the previous embodiment, and the stylus 1000 is mounted on the cartridge 148. Unlike the previous embodiment, the stylus of FIG. 179 does not feature a contraction mechanism. Instead, the stylus is mounted directly to the cartridge 148 which supplies ink and data to the stylus.

As best shown in FIG. 181, the cartridge 148 includes three side tubes 1041, 1041, 1042 in fluid communication with the ink reservoir of the cartridge through channels 1043, 1044, 1045. Each side tube includes a hole 1046 that is filled with a plug 1048 of wick compound that aids in sucking the required ink from the cartridge. The side cover 1050 covers the side tubes to provide a sealed passage through which ink can flow from the cartridge toward the printhead chip.

Despite the fact that the ink is supplied directly from the cartridge rather than along a long conduit, it is dispensed to the printhead chip in a manner similar to that described for the previous embodiment. Power and data are supplied from the MoPEC integrated circuit to the printhead chip via a flexible PCB 1052.

In one embodiment, as shown in FIG. 182, optional modular netpage devices that integrate the infrared LED 1054, coupled optics 1056, and a CCD (not shown) may be included. This netpage device functions similarly to that described elsewhere herein, but has the advantage of being integrated with the cradle. This allows the entire assembly (cradle, stylus, net page device) to be provided to the producer for insertion into the mobile terminal without the need for multiple additional assembly steps.

M-print applied (M- PRINT APPLICATION )

Printing cards from mobile terminals using an M-print system has vast applications in many other fields. For brevity, no application is described in detail herein. However, in order to provide a somewhat comprehensive background on M-print systems, some of their applications are listed below. Of course, this is not a definite enumeration, but merely an indication of its diversity.

The target application may be remote to the phone. For example, as claimed in WO 00/72242 (NPA002), an online purchase method and system, e-commerce applications indicate that a user is shopping by displaying a listing in a printed catalog or advertising using a preferred embodiment of a mobile terminal. You can also add items to the cart. It can also print receipts through a printer in the phone and into a separate pen that allows the user to communicate with the mobile phone via a Netpage pen in the phone (or via a Bluetooth ^™ wireless transmitter and receiver, for example). Sign the receipt so that the transaction can be authenticated.

When the phone knows its own location, it can report its location to selected applications so that the applications can provide location specific services, either through the built-in GPS receiver or via a mobile network device. For example, when a user points to a printed advertising promotion, such as a movie discount offer printed on a product label, the phone may print a valid gift certificate at a nearby movie theater. The term "gift certificate" is used very widely and may include any kind of commercial document. Thus, a "gift certificate" includes a printed medium which conveys advertising without any specific form of incentives, discount coupons, special offers or the like.

For example, a user who visits an unfamiliar city can decide which Italian restaurant he wants to visit. He queries his mobile terminal and brings up a web page that allows him to search for restaurants that are close to his location, price, cuisine and rating. This web page can be hosted and browsed remotely using a local browser application. The local Italian restaurant promoting the promotion is selected, and a voucher for a 10% discount on the meal price is printed by the built-in printer of the mobile terminal. Optionally (or additionally) a map indicating the address of the restaurant and the direction from the user's current location may be printed.

The target application may also be local to the phone. For example, dialing applications, as claimed in WO 01/41413 (NPA060), Methods and Systems for Telephone Control, allow a user to dial numbers by indicating entry in a printed address book or phone book. The netpage clicker or sensor is used by the user to select a phone number or email address on a printed document, which may itself be a printed card made by the phone or another user's phone. If a phone number is selected, the mobile phone may prepare the confirmation on the display to call up the number to be called, or simply skip the confirmation step and dial the number directly. Optionally, a user may be provided with a choice as to what type of communication to perform based on the number. For example, one choice may be given to send a short text message, call the user, or send a voicemail via SMS. Similarly, when an e-mail address is indicated using a mobile phone, an e-mail can be opened to the user in preparation for entering text or adding an attachment. If the netpage pen has been used to write text on a suitable surface (eg, netpage notepad or note paper), the last written text can be automatically inserted in the email to be sent to the selected email address. .

As claimed in the business card as the e-mail token of WO 01/22358 (NPA024) and the business card as the e-mail automation token of WO 01/22357 (NPA025), the business card application can be used to access communication items to a local or network based address book. With automatic insertion, the user can print netpage business cards for presentation to others and scan netpage business cards given to others. This business card application can be near or remote. If purely local, a given business card can be used as a simple single use authentication token to retrieve contact items directly from the provider's phone, for example via a direct Bluetooth ^™ (or infrared) connection.

In related applications, the schedule information stored on the telephone or PDA memory, or on a remote server may be printed on the card. The user can select from options such as, for example, a "to do today" list, a list of all work related appointments next week, or a list of past days. All forms of things, reminders, calendars and related functions can be printed on the card. In addition, the phone or PDA may use a built-in netpage pointer in the device (or use a separate netpage pen, for example, in contact with the device via Bluetooth ^™ ) to input schedule information to the device. In order to be able to do so, it may be configured to print an input template for a day, a week or a month.

In all cases, data being printed by a printer in the device may be stored locally on the device itself or downloaded from a remote server. Also, if a netpage pointer or pen is integrated into the device (or can be individually contacted through the device), the cards printed by the device can interact with the netpage pen or pointer.

Connection history ( Connection History )

The mobile terminal with a print can be used to output a connection history associated with the device. The connection history includes any voice or data related information relating to the transmission or reception of voice, data, text, images or audio and confirmation of the connection associated with the communication of any of these types of data.

For example, the user may have the mobile terminal output a list of up to 10 voice calls initiated by the device. Optionally, the user can print the last call received by the device, or all missed calls within the last 24 hours.

If a netpage clicker or pen function is provided to the mobile terminal (via the built-in clicker / pen, or via an external netpage enabled to contact the device via a wired or wireless link), its printed connection history The information can be used in useful ways. For example, if one of the missed calls is selected from the list, the telephone number dial associated with the communication is turned, or at least recalled on the display of the mobile terminal so that the user can store or dial the number. do. Optionally, selecting a message from the printed "transmitted messages" causes the selected message to be displayed on the display of the device, or even printed by the device for review.

Netpage  Tag pattern printing ( NETPAGE TAG PATTERN PRINTING )

The preferred embodiments shown in the following figures operate on the basis that the cards can be preprinted with a netpage tag pattern. Preprinting the tag pattern means that the printhead does not require nozzles or reservoirs for the IR ink. This simplifies the design and reduces the overall form factor. However, the M-print system includes mobile communication terminals that print the netpage tag pattern simultaneously with the visible images. This requires that the printhead IC have additional rows of nozzles that eject the IR ink. The assignee's very many patents and pending applications disclose full color printheads with IR ink nozzles (see, for example, 11 / 014,769 filed Dec. 20, 2004 (see RRC001US).

There are many options for the mobile terminal to access the necessary tag data in order to generate a bit-map image forming a netpage tag pattern for the card. In one option, the coding for individually identifying each of the tags in the pattern is downloaded from the remote server upon request for each print job. As a diversification of this, the remote netpage server can provide the mobile terminal with the minimum amount of data it needs to generate codes for tag patterns prior to each print job. This variant reduces the data transmitted between the mobile terminal and the server, thereby reducing the delay before the print job.

In another embodiment, each print cartridge includes a memory containing enough page identifiers for its card print capacity. This avoids any contact with the server before printing, although the mobile terminal needs to tell the server which page identifier was used. This can be done before printing, during printing or after printing. The apparatus may inform the netpage server of graphics and / or interactive content printed on the medium, thereby enabling subsequent reproduction of, and / or interaction with, the content of the medium.

There are other options, such as periodic download of page identifiers, and the M-print system can be easily changed to print the netpage tags with the visual bitmap image. However, precoding the cards is a convenient way of authenticating the medium and can avoid the need for an IR ink reservoir, thus enabling a more compact design.
