In addition, although the device to which the transfer device 1 is connected is a PC, it may be a computer-equipped device such as a PDA or a home appliance.

  In such an electronic printer system, information displayed on the monitor device 6 in the PC 4 is displayed and output to one or more predetermined display devices 2 via the transfer device 1.

  First, the basic system configuration shown in FIG. 1 will be described in detail with reference to FIGS.

In addition, the transfer device 1 is connected to the PC 4 with a PC I / F 13a, for example, with a USB 2.0 specification cable. Therefore, the transfer device 1 can be supplied with electric power from a cable connected to the PC, store it in the storage battery 16, and operate with this electric power. 1P is a DC power supply output from the storage battery 16 supplied to each circuit block. The antenna 15 is driven by the antenna drive circuit 14. Here, the antenna drive circuit 14 includes a modulation circuit (not shown) for modulating the carrier frequency.

FIG.

  As shown in FIG. 9, the basic operation of the PC program 3 is composed of three operation blocks: information registration, output setting, and processing. Normally, the PC program 3 waits for the occurrence of each event, and the operation block is executed when the event occurs.

  As shown in FIG. 10, the PC 4 and the transfer device 1, and the transfer device 1 and the display device 2 communicate with each other and operate. Hereinafter, the operation will be described in detail with reference to FIG.

  When the user enters an information registration mode from a menu screen (not shown) of the PC program 3 (step 31), display information such as images and characters to be displayed on the display device 2 on the PC 4 and individual attribute information about the user. Further, individual information for managing the display device 2 is registered. Here, the display information is image information converted into data by a scanner, or document information composed of text, a figure, a graph, a photograph, or the like created by application software. In addition, the user may be used by a plurality of people, such as a person who views information and a person who manages and provides information. Therefore, in order to identify and manage multiple users, various personal information such as name, status and authority in the company, age and password for security management, etc. can be managed to provide diversified convenience. It becomes possible.

  Next, when the user enters the output setting mode from the menu screen (not shown) of the PC program 3 on the PC 4 (step 32), the user performs various output settings for the information to be displayed. For example, a method for sending to the display device, a user specification, a display device specification, a transfer device specification, a display method on the display device, a display period, and the like are arbitrarily set. The output setting information is recorded and saved in the PC 4 or the external storage device 4M connected to the PC 4.

  As an example of setting the method of sending to the display device 2a, the file on the monitor device 6 displayed on the transfer-dedicated window from the PC program 3 is brought close to the transfer device 1, and the transfer device 1 When the PC 4 detects that the display device 2a is recognized, the file can be transferred to the display device 2a using this as a trigger.

  Further, the image display area of the file on the display device 2a is grasped by the PC 4, and when the second display device 2b comes close, image data transfer is performed so that the subsequent image is displayed on the display device 2b. It can also be controlled.

  Here, the information to be displayed can be prepared by processing the information registered in the processing procedure prepared in advance according to the personal information of the user who owns the display device or the user authenticated by the PC 4. Is possible.

  For example, various information processing processes and applications such as displaying only a part of the registered information, combining a plurality of information, and limiting the period during which the information can be displayed are possible.

  Hereinafter, an operation will be described for an example in which a file is transferred from the PC 4 to the display device 2a with a built-in ID.

  Here, it is assumed that the following operation is set as an operation setting for the PC program 3 (hereinafter referred to as a smooth copy operation). (Output Setting Example 1) File selection: As a file to be sent to the display device, information on the window that is in the foreground is selected on a plurality of window screens displayed on the monitor device 6 of the PC 4.

  Output device selection: As a display device that can output, output to a display device in the range of ID = n to n + 20 can be output to only one device (hereinafter referred to as one device complete output mode).

Activation selection: As an operation start timing, the transfer device 1 detects a display device in which an ID is pre-registered by selecting an output device, and starts an operation when the transfer device 1 recognizes the display device.
-Output condition setting: Unconditional.
-Information processing selection: File transfer of window display image.
-Image output specification: Horizontal layout output (output corresponding to how to view the display device in landscape orientation).

                The display device is positioned below the monitor screen display vertically.

(The transfer device is installed at the lower left of the monitor device.)
-Image processing specification: The magnification conversion correction is a simple gradation averaging method.
・ Operation selection: Furthermore, as setting of screen display method in the file transfer operation,
Enables screen synchronous scrolling. ... this operation will be explained later.

    The scroll direction of the monitor screen in the scroll display is from top to bottom in the vertical direction.

    The screen scroll direction of the display device in scroll display is vertical from top to bottom.

    Gray images are added to display additional images on the monitor screen in scroll display.

    The display device is placed on the lower side of the monitor screen.

    Display device screen size conversion uses the same window size as the monitor screen.

  When the transfer device 1 is connected to the PC 4 and power supply is started, the information D1 including the individual ID is periodically output from the antenna 15 as an electromagnetic wave of a predetermined signal (step 11). The display device detection in step 11 and step 12 which serves both as ID transmission and electromagnetic wave supply is continuously repeated. Here, as shown in FIG. 1, when it is detected by the received power in step 21 that the user is close to the transfer device 1 with the display device 2 a and is located within a distance where the electromagnetic wave can be received, the display device 2a uses the energy of the electromagnetic wave as power to send information D2 including the individual ID of the display device 2a to the transfer device 1 (step 22).

  The transfer device 1 transmits the information D3 including the ID (m) of the transfer device 1 to the individual ID of the display device 2a detected in step 12 to the PC 4. When the ID is sent, the display device 2a receives the electromagnetic wave from the transfer device 1 and charges the storage battery 26 with energy (step 23). Subsequently, until the command from the transfer device 1 is received in step 24, the process waits while repeating the ID transmission in step 22 and the charging operation in step 23.

  Here, in this example, considering that the display device 2 is used close to the transfer device 1, the distance is determined according to the amount of power supplied from the transfer device 1, and the communication of the display device 2 is performed. The start of operation is restricted.

  In the case where the communication distance between the transfer device 1 and the display device 2 is extended as a near (70 cm or less) type, the IDs sent from the display device 2 are simultaneously generated when a plurality of display devices are brought close to each other. In order to avoid a collision of transmission operations due to timing, ID transmission timing may be set by random numbers using the electromagnetic wave reception in step 21 as a trigger, and means for reducing the occurrence of simultaneous output may be taken.

  The PC 4 receives the detection of the display device 2a or 2b and the ID information from the transfer device 1, and determines whether or not the display device is selected from the individual information set in advance in step 32. (Step 33). Further, when the specification (for example, resolution and the number of pixels) of the device is grasped from the ID of the display device and it is confirmed that the specified output condition is satisfied, the output setting set in step 32 is performed next. Information processing is performed according to the information (step 34).

  Here, the material Y is displayed in the foreground window W1 on the screen of the monitor device 6 (FIG. 8A), and the image of this display window is transferred to the display device of ID = n to n + 20. Therefore, as the information processing, by recognizing the display device 2a with ID = n + 1, the window size is made the same from the display resolution of the display device 2a and the display resolution of the monitor device 6. Then, the pixel magnification conversion processing of the image data is performed by the designated simple average gradation processing to create data to be transferred, and the display data of the window W1 of the monitor device 6 is stored for an arbitrary number of pixels (for example, two pixel rows) Min) Scroll to rewrite the display. Here, as for the image newly added to the window W1 of the monitor device 6, gray image data is added to the upper two pixel rows according to the setting.

  In data creation, a process of making the apparent size the same is performed according to a ratio determined from the number of pixels and the pixel size of each of the monitor device 6 and the display device 2. For example, when the monitor device 6 has the number of pixels of 2048 × 1536, the display device 2a has the number of pixels of 1024 × 768, and these pixel sizes are the same and output horizontally, the file transfer destination display device 2a is the monitor device 6 Therefore, in order to make the apparent size the same, it is necessary to thin out the number of pixels to 1/2 in both the vertical and horizontal directions. The simple average gradation processing designated here indicates processing for creating data of one pixel by averaging four pieces of pixel information of 2 × 2 pixels in the vertical and horizontal directions. In addition, in the area corresponding to the outside of the window W1, white or black fixed data is created.

  After the information processing, the PC 4 extracts the bottom row data after the magnification conversion processing corresponding to the image data of the material Y displayed in the front row window of the monitor device 6, and detects the display device 2a as an image output command. It is transmitted as information D4 to the transfer device 1 with ID = m (step 35). As shown in FIG. 11, the information D4 includes, as command information, an operation command (image display in this example) which is information for instructing device operation, a transfer device ID and display device ID indicating the command destination, and image data to be transferred (this In the example, data for one line of the image of the document Y and surrounding margin data) and command attached information for setting details regarding the operation command are provided. Note that the command attached information of this embodiment includes command attached information such as a screen synchronous scroll operation with the same window size as an attached operation setting in the image display operation.

  When the transfer device 1 receives the command information D4 from the PC 4 (step 13), the command is processed. Since the transfer device 1 detects and grasps whether the display recording device 2a with ID = n1 is located within the receivable range of the transfer device 1, if it is within the range, image transmission is performed as a command process. Do. In the image transmission, the image information of the material Y and the command ancillary information are transmitted from the antenna 15 as information D5 together with the command information indicating that the output is to the display device 2a with ID = n + 1 (step 14). If the designated display device 2a cannot be detected, the transfer device 1 waits while repeating step 11 to step 12 until the display device 2a can be detected.

  When the display device 2a receives the information D5 from the PC 4 via the transfer device 1 (step 24), the display device 2a enters display drawing processing (step 25).

  Here, in the received image display operation called the screen synchronization scroll operation, first, as shown in FIG. 8 (a), the content displayed on the display device is cleared to the first state where nothing is displayed. Next, the received image data for one line is displayed and drawn on the display device 2a.

  In the display drawing of the display device 2a, the CPU 21 sends the received image data for one line of the screen to the recording control circuit 28 as shown in FIG. The recording control circuit 28 controls the drive circuit 28R in the column direction and the drive circuit 28C in the row direction corresponding to the pixel to be rewritten, and writes an image on the electronic paper of the display unit 27B.

  Here, the driving of the pixel electrode 27BS may be either a passive method or an active method.

  When the display information writing for the received one line is completed in the display drawing process, a command processing completion signal D6 is transmitted to the transfer apparatus 1 together with the command information and the ID information (step 26).

  When receiving the command completion from the display device 2a (step 15), the transfer device 1 outputs a response signal D7 from the antenna 15, and subsequently transmits command completion information D8 to the PC 4 from the PC I / F 13a (step 16). ), And waits for a response from the PC 4 (step 17).

  After the command is output in step 35, the PC 4 proceeds to step 36 and waits for the command completion information D8 from the transfer device 1. When the command completion information D8 is confirmed, the PC 4 transmits a response signal D9 to the transfer device 1 for processing. Proceed to recording (step 37). In the process recording, the PC 4 records history information that a part of the designated process has been completed in a storage means (not shown) in the PC 4 or an external storage device 4M connected to the PC 4. For example, the number of lines transferred in the screen synchronous scroll operation is cumulatively counted, and log information such as the value, the ID of the copy destination display device, and the copy time is recorded.

  Then, the above series of operations is repeated as many times as the number of rows in the front row window screen on the monitor device 6. FIG. 8B is a diagram showing a second display state after the data transfer for several lines and the scroll display thereof are performed. The window image displayed first is scrolled, and then the additional image is displayed. W1a is displayed. In addition, the same number of image data as the number of scrolled lines is displayed in the window W21 of the display device 2. FIG. 8C is a diagram showing a display state after all the images displayed in the window W1 have been transferred to the display device 2. The display device 2 initially displays the image in the window W1 of the monitor device 6. An image that looks the same as the displayed image is displayed.

  In the above image transfer command, the untransferred image data of the portion of the material Y that is not displayed on the front row window screen is further subjected to pixel magnification conversion processing and added, and the positional relationship of the image to the ROM / RAM 22 of the display device 2a. It is also possible to transfer the image data of all the materials Y together with the data to which the information (for example, the row number label) is added.

  When the transfer apparatus 1 receives and confirms the response signal D9 from the PC 4 (step 17), the transfer apparatus 1 returns to the first step 11 and repeats the operation of the series of transfer apparatuses.

  When the display device 2b is brought close to the transfer device 1, if the output setting is not the complete output mode for one device but the same copy output mode for a plurality of devices, the same operation is brought closer to the transfer device 1 later. The display device 2b and other display devices 2x whose IDs are in the specified range are repeatedly operated.

  Further, when the display device 2b is brought close to the transfer device 1, if the output setting is not the complete output mode for one device but the continuous output mode for a plurality of devices, the document 1 being transferred and displayed on the display device 2a is displayed. A continued part of the image data (if it is a page, an image corresponding to the next page) may be transferred to the display device 2b.

  In step 32, when there is no setting to be commanded in the recorded output setting, the process transits to the event waiting state shown in FIG.

  According to such a configuration, the electronic printer system of the present invention communicates with the display devices 2a and 2b by the transfer device 1 in a non-contact manner, detects the display devices 2a and 2b, and uses the solid identification information of the display device for the PC. Recognizing by the program 3, various data processing is performed from information and processing procedures set and registered in advance based on individual identification information, and image information and operation commands are sent to an arbitrary transfer device and desired display is performed. The display on the device can be controlled and managed.

  In addition, since power is wirelessly supplied to the display device, in the case of cordless, there is no need for a power supply unit whose volume increases in proportion to the length of continuous operation time, and the AC / DC conversion circuit 24, antenna 25, and small capacity are not required. Since it can comprise only the storage battery 26, a display apparatus can be made lightweight and thin.

  In the user interface, after setting the output, simply move the display device closer to the transfer device, and you can transfer and display the desired information on any display device. A printer device that takes up space is unnecessary, and a copy can be obtained in the form of paper at the place where the user is working. Furthermore, by visually showing that the image data flows from the screen display of the monitor device to the display device, it becomes an illusion that the paper on which the information is written is converted into a display device held in the hand, so that the information is real-time It is possible to provide an unprecedented printing solution environment that allows users to feel that they are being transferred via the Internet.

  In addition, since electronic paper can be repeatedly written and erased, it can be used for the purpose of reducing paper resources that have been wasted by trial printing of created materials.

  Also, the angle of the antenna part of the transfer device can be rotated to an arbitrary angle with respect to the attached monitor screen, so that the coupling rate between the antenna of the transfer device and the display device is improved, and the efficiency of wireless communication and power supply is improved. it can.

  In addition, even if the display device is moved and becomes unable to communicate in the middle before the data transfer is completed, and the process is interrupted, the display device can be transferred to the transfer device again by managing the process progress information. When the communication becomes possible, only the remaining copy information can be transferred, and the operational stability can be improved.

  In the description of the present embodiment, the processing example of the image information related to the size that can be displayed on the electronic paper from the information of the material Y is described as the information processing, but the image that displays only a part of the material Y from the user attribute By making various information processing, such as processing as information, adding other information to document Y and processing it as image information, etc. Various conveniences such as advertising effects can be realized.

  For example, when the original image data is shown in FIG. 12A, the name information Da1 of the copying user can be added to the image as shown in FIG. 12B. Further, as shown in FIG. 12C, image display restriction information Da2 regarding the period and place can be added to the image.

  In this embodiment, the scroll display is controlled to flow from the top to the bottom with respect to the display device located on the lower side of the monitor device. Attaching to the display device, setting the position of the display device according to its positional relationship, various images such as flowing from left to right, flowing from bottom to top, flowing from right to left, etc. Needless to say, the setting can be made possible.

  Further, in the present embodiment, in the present embodiment, the image display on the monitor device side is a scroll display and a gray image row is added from the top, but before or after it was initially hidden and not displayed. The corresponding image can be additionally displayed, the image of the transferred part can be displayed in black and white reversed without scroll display, or the density and color of the image can be changed to notify the user of the transfer part of the image.

  Further, in the present embodiment, the transfer device is connected to the PC by a cable, but can be connected by a wireless communication means such as Bluetooth or a wireless LAN.

It is a figure which shows a 2nd state.

  As shown in FIG. 13, a transfer device 1 </ b> M in which a known mouse function for PC 4 is added to the transfer device 1 is placed beside the display device 2. An antenna 15 (not shown) is built in the bottom surface of the transfer device 1M. The mouse function is the same function as a mouse device that is generally used as a PC pointing device. The mouse function includes means for measuring the displacement of the position movement and a plurality of switches. It is equipped with means that can communicate. The PC 4 is omitted and not shown.

  As shown in FIG. 14, the display device 2 according to the second embodiment includes antennas 25 arranged at two corners on the lower right and the lower left. Note that the circuit excluding the display portion and its recording control circuit is preferably arranged only on one side of the display device.

  As shown in FIG. 15A, the transfer device 1M having a mouse function is moved to select the window W1 displayed in the monitor screen with the mouse cursor and display it in the foreground, and the transfer device 1M is displayed in the window W1. The right button is clicked to activate the output setting mode, the operation menu Dm1 is displayed, the desired operation is selected with the cursor, and settings such as the output setting example 1 are performed. In this figure, a place where “complete”, which means a complete output mode for one file transfer, is selected is displayed on the monitor screen.

  Then, as shown in FIG. 15 (b), when the transfer device 1M whose communication mode is close proximity communication is placed on the antenna unit 25 of the display device 1, the communication operation is performed between the transfer device 1M and the display device 2. Is started, and only the image data displayed in the window W1 is sequentially transferred to the display device 2 and displayed in the window W21. When the PC 4 and the transfer apparatus 1 finish sending image data that has been subjected to information processing corresponding to the image data initially displayed on the front row window screen W1 of the monitor device 6 to the display device 2, the front row window screen W1 is displayed.

  It should be noted that only the operation method is changed from the case of FIG. 8B, and the screen display operation similarly shows the screen synchronous scroll operation.

  Further, after all the data transfer of the material Y is completed, the buzzer 18 provided in the transfer device 1 is operated by the buzzer driving circuit 17 to notify the user of the completion by sound.

  According to such a configuration, the information and power from the PC 4 can be transferred and supplied to the display device 2 only by operating the transfer device 1M with a built-in mouse function while the display device 2 is placed on the desk. Furthermore, if the number of lines for which display image data has been transferred is monitored, the display image from the next line is continued even if the transfer apparatus 1M is moved from the display apparatus 2a to another display apparatus 2b during the transfer. As a result, it is possible to improve the cooperation between operation and transfer.

  In addition, a peripheral circuit that has a higher specific gravity than the display unit or a hard configuration with less flexibility is arranged along with an antenna on one side of the display device. Because it is easy to hold, it is hard to get tired.

FIG. 16 is a schematic diagram of an electronic paper drive circuit according to Embodiment 3 of the present invention, and FIG. 17 is a diagram illustrating a configuration of a pixel drive circuit according to Embodiment 3 of the present invention. In FIG. 16, the same constituent elements as those in FIG.

  Furthermore, it demonstrates in detail together with the display drawing process part of the display apparatus 2 shown in FIG.

  In step 24 shown in FIG. 10, when the display device 2a recognizes that it is an image output command by the screen synchronous scroll operation, the image information for one line of the document Y sent together is stored in the ROM / RAM 22 incorporated therein. Store.

  In step 25, the display device 2a performs image processing on the received image data based on the command attached information (however, since the command has already been processed by the PC 4 and drawing at equal magnification is possible, nothing is done on the display device side. No), the processed image data is written to the electronic paper 200a through the recording control circuit (drawing process).

  Note that the image data of the material Y is transferred from the PC 4 without processing, and can be enlarged or reduced on the display device side.

  A specific operation of the drawing process will be described with reference to FIGS.

  As shown in FIG. 16, each pixel electrode 27BS is connected to the pixel drive circuit 27SC, and the pixel drive circuits 27SC in the same column are connected by the same source line 27C (x) from the drive circuit 28C in the column direction. The pixel drive circuit 27SC is connected by the same gate line 27R (x) from the drive circuit 28R in the row direction.

  As shown in FIG. 17, the pixel drive circuit 27SC includes AND and OR logic circuits, a flip-flop circuit 27FF, and a buffer circuit 27BF, and two pixel inputs G1 and G2 are switched between these pixel input signals by an input S. The selected pixel input data can be held in the flip-flop circuit 27FF by the clock K. The output of the signal held in the flip-flop circuit 27FF has * Q, which is the inverse logic of Q and Q, and * Q is connected to the input of the buffer circuit 27BF. Here, the output O of the buffer circuit 27BF is connected to and driven by the pixel electrode 27BS.

  The signal output Q held by the pixel drive circuit 27SC is connected to the pixel input G1 of the pixel drive circuit 27SC in the next row of the same column, and all the columns are similarly connected in cascade.

Pixel data can be written directly to the gate line 27R (n) to which the pulse is applied. For example, when all the display images are cleared first, L level is output to the same value 27CC from all the drive circuits 28C in the column direction to all the source lines 27C, and the drive circuit in the row direction is supplied to all the gate lines 27R. This can be achieved by applying a pulse 27P from 28 and writing to the pixel drive circuit 27SC. It should be noted that the same value 27CC can be set to the H level and the display density can be inverted.

  Subsequently, the L level is output to the mode switching signal 27M (hereinafter referred to as the shift mode), and the gate line 27R (x) on the final column side is set with the S inputs of all the pixel driving circuits 27SC set to the L level. If the pulse is applied to the gate line 27R one line at a time, the pixel data of the upper row is copied to the lower row one row at a time, so copying proceeds in order from the lower column, As a result, one-line scroll drawing can be performed. Here, in the pulse application period from the gate lines 27R (x) to 27R (2), the signal output 27C of the drive circuit 28C may be either L / H level (27CB).

  Since the G2 input of the pixel drive circuit 27SC in the first row is the same as G1, and the output signal of the drive circuit 28 is connected, the gate line 27R (1) of the first row from the drive circuit 28 in the row direction is connected. When the pixel data 27CN for one row is output from the drive circuit 28C in correspondence with the output of a pulse to ()), new data is written to the pixel drive circuit 27SC of the first row.

  If the scroll operation is repeated for the total number of lines, the window display image can be displayed as if it were moved to the display device 2 line by line.

  According to such a configuration, in the display device 2 of the electronic printer system of the present invention, the scroll display can be written to the display unit with a smaller number of times of writing compared with the case of scroll display with a normal active matrix circuit, thus saving power consumption. Can do. Further, when data is written to the display unit only in the shift mode, the memory capacity for the entire screen is not necessary, and the memory capacity for one line can be provided.

Next, the antenna pattern is covered with an insulating material AZ (for example, an alkali development type insulating paste used in photoresist, ethyl cellulose, or PDP) (FIG. 20 (2)). However, as shown in FIG. 21, the insulating material is not applied to the portion TP that is stacked and upper layer.

  As shown in FIG. 20 (3), the magnetic body AU1 is arranged to focus the magnetic flux inside the antenna pattern, and the magnetic body AU2 is arranged outside.
