[Detailed Description of the Invention] [Industrial Application Fields] The electronic file according to the present invention is a book (B o
ok) is equipped with an integrated circuit, etc., and data such as explanations and images are written on each page in advance in memory, or the user can write them, and there is a dedicated output playback device or The stored contents can be played back using a general television, radio receiver, or stereo player.

Therefore, the electronic file of the present invention can also be used for playing back images and sounds such as graphics and animations related to the contents of books such as ordinary books and files, and for playing games.

For example, it is convenient to apply this method to a case where data such as CAD-CAM data is written in a blueprint and a computer displays a completed image using a three-dimensional image or graphics.

In addition, changes to design details, which are currently handled by replacing two drawings, etc., can be done by recording only the rough drawings on the designated pages of the book, and storing the details in memory as CAD data. You can easily make changes by setting the

Furthermore, in the case of cooking books, by storing data such as the ingredients and cooking methods of the completed dishes in memory, instructions can be obtained in real time using a dedicated playback device or an externally connected personal computer.

Furthermore, it can be used in a wide variety of fields, such as in physical education classrooms, etc., where animation can be used to teach dynamic things that cannot be conveyed through calligraphy or drawings alone.

[Prior Art] The content that can be recognized from conventional books and files of materials is only static fixed information that is obtained by silently observing.

To recognize this in a video format and with sound.

Although there is a method of using a video playback device and its storage medium, such as a recording tape or a disk, it is inconvenient because it requires handling separately from printed matter etc. expressing the contents.

In addition, there is an integrated circuit card, i.e., an IC card, which is currently in practical use as having a function similar to that of the present invention.
(Integrated C1rcuit) card. This is a technology that takes advantage of the characteristics of ultra-miniaturized integrated memory, which means that it can contain large-capacity storage devices.

However, an IC card literally refers to the contents of a portion of the card, and the electronic file according to the present invention is a technology in a field that differs in purpose, structure, scale, and use.

[Purpose of the Invention] The purpose of the present invention is to attach electronic circuits such as ultra-small and large-capacity storage devices and control circuits to files and books consisting of sheets on which letters, pictures, etc. are written or printed, and The goal is to provide electronic files that have active functions added to existing files and books.

[Summary of the Invention] The electronic file of the present invention is a book that is made up of sheets in which two characters, pictures, etc. are written or printed, and an electronic circuit that handles information corresponding to the content of each page, that is, an information holding circuit, An information file equipped with a page determination circuit, a signal control unit, and a passive transmitting/receiving unit, and a data processing unit 9 having a function of reading and writing information to this information file.
The driving device is equipped with a vibration circuit, a signal control section, a signal control section, and an active transmitting/receiving section, and transmits power from the active transmitting/receiving section to the passive transmitting/receiving section in a non-contact manner, and also mutually exchanges information. The present invention is characterized in that it has a function of expressing the contents of the information file on a playback station connected to a drive device.

[Structure of the Invention] The electronic file of the present invention is a passive information file that holds various types of information for a book in which two characters, pictures, etc. are written or printed, and an active information file that commands and executes reading and writing operations. It is constructed by adding an input/output section for inputting or outputting the contents of the information file and a driving device for the system.

Such electronic files can be roughly divided into two types: those that have both write and read functions for the information file, and those that have read-only functions, but the former generally includes the latter function. Therefore, in this article we will discuss the former configuration.

The information file consists of 2 sheets in a normal format bound with 1 sheet containing letters, pictures, etc.
It is equipped with the following electronic circuit. In other words, an information storage circuit mainly composed of IC memory that stores information such as data and programs corresponding to the contents of each page, a page determination circuit that determines the currently opened page, and the operation and timing of these circuits. It is equipped with a signal control section that performs control, rectification, detection, etc. In addition, there is a passive transmitting/receiving section that consists of a transmitting coil and a receiving coil.

This is a part that directly controls the reception of power transmitted non-contactly from the drive device described below using electromagnetic waves as a transmission medium, and the exchange of information signals.

In this case, the received power is supplied to each circuit of the information file as necessary operating power, and a portion of the power is used to charge the battery attached to the rectifier and smoothing circuit, which is then used for data retention and other operations. Supply it as power.

On the other hand, the configuration of the drive device includes a data processing section that processes the data transferred from the information file and sends it to the playback device, and a data processing section that processes the data transferred from the information file and sends it to the playback device. An oscillation circuit that oscillates the reference frequency of the signal, a signal control section that controls the operation and timing of these circuits, amplifies and detects a predetermined modulated wave, and a non-conductor coil that faces each coil of the passive transmitter/receiver section. It is equipped with an active transmitter/receiver that controls the transmission and reception of electromagnetic waves through contact.

The input/output section includes a signal input section into which information signals such as operation command signals and data and commands for writing/reading thereof can be input using a keyboard, etc., and a playback section which outputs information from the data processing section as images and sounds. Consists of equipment, etc.

These driving devices and human output units may be installed in the binding section of the book together with the information file, or may be installed separately from the information file depending on the purpose of use.
In some cases, only the transmitter/receiver for fI'fi operation is attached to the book, and the other parts are installed separately outside.

The electromagnetic waves used as a medium for non-contact transmission of power and information signals between the coils of the active and passive transceivers include those in the radio frequency range from low frequencies to microwaves, which are alternating currents above the commercial frequency. Applicable.

In this case, there is a method in which electric power and information signals are transmitted from the transmitter coil of the drive device to a receiver coil for the information file using electromagnetic waves in which power and information signals are superimposed, and a transmitter coil dedicated to transmitting power is provided in the drive device. There is a method of creating a separate system.

However, the information signals that can be transmitted between a pair of transmitting and receiving coils and handled by their processing circuits are generally serial signals. Furthermore, multiplexed signal transmission is possible using a time division method using various pulse modulations and frequency modulations. Furthermore, depending on the purpose of electronic file operation or the content of required processing, it may be effective to arrange a plurality of coils and operate them in parallel.

Since the shape of these coils is required to be as flat as possible, single-layer or laminated planar coils such as sheet coils are used.

Also, if a common clock is required for the drive device and the information file (for example, if the baud rate clock is shared when transmitting data serially).

By modulating the electromagnetic wave for power transmission with that frequency, or by setting the frequency of power transmission to an integral multiple of the clock frequency you want to transmit, it is easy to match the scale between the information file and the drive device, and it is possible to use a common clock. Since it can be operated, it is possible to stabilize the two functions.

Next, embodiments of an electronic circuit and a specific book structure according to the present invention will be described based on the drawings.

Example 1. Figure 1 is an example of an electronic circuit constituting the electronic file of the present invention, and is an embodiment in which one page of an information file is made to function independently. The part C shows the block diagram of the input/output section, and I! The system B is normally operated by externally supplied commercial power or batteries.

First, when writing data from the drive device B to the information file A, the data processing unit l, which has communication with the host computer, data editing functions, etc., converts the parallel data handled internally into the oscillation circuit 2 at the oscillation Wi7iJJ wave number. is converted into serial data in advance by referring to the baud rate clock BR which has been decreased by the frequency divider 3.

This output passes through an interface 4 and becomes an F/S modulated wave by an F/S (frequency shift) modulation circuit 5 driven by a nine oscillation circuit 2. After power amplifying this by a power amplifier 6, it is propagated as an electromagnetic wave from a transmitting coil 7 of an active transmitting/receiving section.

In this case, the data sent from the data processing section l is.

These are information signals such as a write command for information file A, its storage address, and data to be transmitted.

The electromagnetic waves of power and information signals radiated from the transmitting coil 7 as described above are received by the receiving coil 8 of the passive transmitting/receiving unit provided in the information file A, and a part of the energy is converted into DC by the rectifying smoothing port VA9. Each circuit in the information file A and the rectifying and smoothing circuit 9. It is supplied for charging the built-in battery attached to the device.

Also some other part of the received electromagnetic energy.

The frequency divider 10 reduces the frequency to return the same BH as the baud rate clock in the drive device B, and then supplies it to the controller 12 via the interface 11.

The other part of the electromagnetic wave energy received by the receiving coil 8 is detected by the F/S detection circuit 13 and demodulated into the original serial data, and then passed through the interface 11 to the controller 12 consisting of a microcomputer and logic circuit. is man-powered.

This input data is converted into parallel data by a program inside the controller 12 with reference to the baud rate clock BR, and predetermined data according to the previous write command is written into the memory 14.

As described above, data is written from drive device B to information file A. However, if the information signal sent from data processing section l of drive device B is a command to read data from information file A, inputs this to the controller 12 through the same route as above, and stores it in the memory 14.
is accessed and stored at the specified address, and the corresponding data is read out. Then, the controller 12 converts it into serial data again, and the 2-frequency conversion circuit 15
The frequency of the output of the receiving coil 8 is used as a reference and is converted to a frequency suitable for transmission by the F/S conversion circuit 16 driven by this output. The power amplifier 1
7, the power is amplified and radiated from the transmitting coil 18 as an electromagnetic wave.

This electromagnetic wave data is received by the receiving coil 19 of drive device B, and then F/S detection circuit! After being demodulated into serial data by 20, the data is manually inputted to data processing 1111 via an interface 4 that performs voltage adjustment and buffering.

Then, the data processing section 1 converts the data into parallel data with reference to the baud rate clock BR.

The data read from the information file A undergoes necessary internal processing and is output to the playback device 22.

The drive device B is connected to a signal input section 23 that gives operation commands using a dedicated manual keyboard, switches, etc. arranged in the human output section C, and thereby turns on and off when operating electronic files and controls the data processing section. Various operation command signals can be given to the control unit 1.

Further, the page determination circuit 21 determines the page of the book that has been written, and specifies the page to the controller 12 via the interface 11. However, if it is desired to specifically designate a page other than the relevant page and output it to the reproducing device 22, the command can also be input manually from the signal input section 23 described above.

21st! I shows an example in which each electronic circuit of the information file A attached to each page of a book is configured in a card shape. In other words, a receiving coil 8 and a transmitting coil 18 made in a planar shape are loaded into an outer cover 24 made of a plastic material or the like.

An information holding circuit, a page judgment circuit, a signal control section, and other electronic circuits are installed near the center of the LSI (LSI).
5cale Integrated Circuit)
A functional module 25 is implemented.

In this case, the receiving coil 8 and the transmitting coil 18 are usually used with capacitors connected in parallel to both ends thereof.

Furthermore, as shown in FIG. 3 which illustrates these cross sections.

By applying a magnetic core 27 made of ferrite or the like having sufficient magnetic permeability for the operating frequency to each coil 26, the inductance can be increased with a small number of windings.

The electronic circuit of drive device B is also made to have a flat structure in substantially the same way, but its transmitting coil 7 and receiving coil 19 are arranged so as to be in close contact with and face each of the coils 8 and 18 of information file A, respectively.

The secondary lever enables efficient transmission and reception of electromagnetic waves in a state where one or more pairs of such planar coils are closely opposed to each other.

In addition, there are several possible ways to arrange the coils in a card-shaped electronic circuit, such as arranging a fill or multiple coils symmetrically on the card surface, or arranging multiple coils perpendicularly or obliquely to each other. For example, crosstalk between power and information signals can be prevented by arranging them.

Various configurations can be applied, such as interposing a shield layer to prevent magnetic or electrical induction to the memory or processing circuit.

FIG. 4 is an example showing a specific configuration of an electronic file of the present invention equipped with each of the electronic circuits described above.

Text and pictures are printed on sheet 28 on the left page of the book, which is opened as shown in the diagram.

The information holding circuit, page determination circuit, signal control section, and passive transmitting/receiving section corresponding to the contents are mounted on the sheet 29 of the right page. Therefore, the front side of each sheet constitutes the printing surface, and the back side constitutes the mounting surface of the information file A.

Most of the electronic circuits of the drive device B are mounted on the front cover 30, and the transmitting coil 7 and the receiving coil 19 are built into the inner cover 31, which can be folded back from the front cover, as well as a flat human-powered keyboard and switches. A signal input section 32 for operation commands, etc., is mounted.

When opening another page, the inside cover 31 is opened as shown by the dotted line in the figure, but usually the inside cover 31 is opened.
As shown in Fig. 2, the coils 7 and 8 and 18 and 19 of the active and passive transmitting/receiving sections are closely opposed to each other by the elasticity of a spring or the like built into the flexible back cover 33 of the seat 290, as shown in Fig. 2. It is set as follows.

Therefore, this electronic file is stored in the drive device B shown in FIG.
However, since the electronic circuit of the information file A is basically mounted on each page, one book is composed of a plurality of sets corresponding to the required number of pages.

The inside cover 31 is equipped with a playback device 22, which is a small and flat video playback device or audio device that operates on low power, such as a liquid crystal image device.

In addition, the content of the data is expressed in the output signal from the data processing section 1 of the drive device B using images, sounds, and the like.

T is a connection terminal for introducing power to the driving device B, or a connection terminal for connecting various playback devices externally connected as necessary.

Example 2. FIG. 5 shows another example of the structure of the electronic file of the present invention. Basically, it operates based on the electronic circuit shown in Figure 1, but this book contains only the information file A, which is mounted on a pedestal with only the active transmitting and receiving part of the drive device B installed. 34, the two are automatically joined together. Therefore, the pedestal 34 has the feature that it can be shared by several different books. .

In other words, the functional modules 35 of each electronic circuit having the function of the information file A are collectively attached to the back cover 36.
The receiving coil 8 and transmitting coil 18 are built into the surface of 0. The transmitting coil 7 and receiving coil 19 of the drive device B are mounted on the pedestal 34 so as to face these coils.
It is attached to. Other electronic circuits of the drive device B are connected to the outside from the terminal T of the two seats 34.

Also, human output section C for inputting operation command signals and reproducing output.
The operation is also carried out by a device equivalent to a personal computer connected to the outside from the terminal T of the two pedestals 34.

In this case, the basic configurations and functions of the information file A and the drive device B are almost the same as those in the embodiment shown in FIG. 1, so a detailed description thereof will be omitted, and an example of the configuration of the page determination circuit will be mainly described.

As shown in Figure 5, there is a page code 37 with bars and spaces arranged according to the BCD code.

It is printed on the edge of each page in a color that contrasts with the color and gloss of the surface of the sheet 28 of each page and that matches the spectral sensitivity characteristics of the photoelectric sensor 38. This page code 37 is read from an oblique direction by a group of photoelectric sensors 38 using the fact that the nine spaced pages are illuminated by natural light.

The page is determined based on each output signal, and is input to the controller 12 via the interface 11 shown in the first factor. The controller 12 stores the memory 1 corresponding to the page.
4 is determined and predetermined data processing is performed.

In each of the above embodiments, when the information file A is equipped with a battery necessary for memory backup and other operations, the secondary battery attached to and built in the rectifying and smoothing circuit 9 in FIG. Depending on the program, the battery is automatically charged by the DC power source E each time or as needed, and then used for a specified purpose.

Information file A also contains information on power-generating photoelectric elements such as solar cells that operate by receiving external light, and long-life primary batteries.
It may also be built into the auxiliary power source.

In these embodiments, the case where F/S modulation is used as the information signal transmission means has been described, but it goes without saying that various modulation methods commonly used in wireless communication etc. can be applied.

[Effects of the Invention] The electronic file of the present invention incorporates an electronic circuit that stores, reads, and writes data and programs related to each page into a current general book or other file, and converts that information into a moving image. By being equipped with a playback device that expresses visual images and sounds, active functions have been added to so-called books, such as books and files, which were previously only passive.

Therefore, as mentioned in the [Industrial Application Fields] section at the beginning, data such as explanatory texts and images related to the texts and paintings printed on each page of the book can be written in advance into memory. Various types of memory contents written by the user can be reproduced in relation to the contents of the page using a specially equipped reproduction device or an externally connected general television, radio receiver, stereo reproduction device, or other reproduction device. Images and sounds in graphics, animation, games, etc. can be easily reproduced in a consolidated form. As a result, it has the advantage that it can be easily used not only at home but also in the industrial and hobby industries.

Furthermore, since data and control commands are transmitted between the information file and the drive device using a non-contact method using electromagnetic waves, electronic information can be transferred with the same effort as with current books, with only the hassle of checking a predetermined page. It has the benefit of being able to obtain abundant amounts of. In addition, it has the feature that it can eliminate the factors that cause a decrease in reliability due to poor contact due to wear and corrosion of the connecting parts, leakage between contacts, etc., which were the biggest instability factors in conventional contact systems.

In this case, the coils that directly use electromagnetic waves to transmit and receive power and information signals can be precisely constructed into extremely thin planar shapes using single-layer or laminated printed wiring or vacuum evaporation technology. Since it is fixed integrally with the connected electronic circuit, it has the great effect that its electrical operation is extremely stable and robust.

Furthermore, since the power necessary for data retention and other operations in the information file is sent from the drive unit in a non-contact manner as described above, 9 normally the information file does not require power supply equipment. Moreover, since the electronic circuit of the information file automatically charges the built-in battery at all times or as needed, there is no need to worry about periodic battery replacement or additional charging work. .

Furthermore, by using the frequency for power transmission as the reference clock between the information file and the driving device, it is possible to simplify the two-circuit configuration, and it has many effects such as stabilizing the operation.
