Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information service system. As one form of the information service system, so-called personal computer communication has already been widely put into practical use. In addition, as another form, electronic publishing that sells a storage medium in which information has already been recorded has already been put into practical use. The present invention describes a novel information service system which is different from the above-mentioned personal computer communication or electronic publication.

[0002]

2. Description of the Related Art An information service system according to the present invention is
Among the conventional forms, it takes the form closest to the above electronic publication. In this electronic publication, information sources such as books and magazines supplied from publishers are recorded in advance in a fixed storage medium, mainly a CD-ROM, and information is already recorded in the C.
The user purchases the D-ROM and obtains the information from the playback device owned by the user.

[0003]

The above-mentioned conventional electronic publishing has various problems. (1) The first problem is that the target of the information service is limited to a certain book or the like, and the range of information sources that can be provided to the user is limited. That is, the storage medium in conventional electronic publishing is mass-produced at the publisher's factory,
It is delivered to retailers, etc. by the same transportation route as for ordinary books. For this reason, only the product (storage medium) having the information that can be expected to be sold in large quantities can be provided to the user, and the range of the information source is extremely limited.

(2) The second problem is that it is extremely uneconomical for the user to handle transient information, for example, information sources such as newspaper morning editions and evening editions. Mass sales of such information sources can be expected. However, it is usually one-time information for the user, and it is not economical to purchase an expensive storage medium each time. (3) The third problem is lack of immediacy. In addition to the above-mentioned newspaper information, it is significant that stock information, exchange information, etc. have immediacy. However, it takes at least several days to write such information in a storage medium at a factory and to put it on a distribution channel, and the information value becomes extremely low by the time it is provided to users.

(4) The fourth problem is that the places where the user can see and listen to the information on the storage medium are limited. Therefore, in view of the above problems, it is an object of the present invention to provide an information service system capable of satisfying enrichment and diversification of information sources, high economic efficiency, promptness of information acquisition, and simplicity of information display. To do.

[0006]

FIG. 1 is a block diagram showing the principle configuration of the present invention. As shown in the figure, the main components of the information service system according to the present invention are an information center 10, an information server 20, a copy card 30, and an information viewer 40. The information center 10 stores various kinds of information to be provided to users.

The information server 20 comprises a communication means 21 for communicating with the information center 10, a buffer means 22 for temporarily holding the information obtained via the communication means 21, and a writing means 23 for writing the information in an external recording medium. The copy card 30 forms the external recording medium and copies the information once held in the information server 20.

The information viewer 40 is a copy card 30.
Is provided, and the information in the copy card 30 is read and displayed to the user.

[0009]

The information center 10 for storing digitized information in a publishing company or a newspaper company is usually far from users. This information center 10 (database)
It is the information server 20 that is installed near the user. The information server 20 temporarily holds the information in the information center 10 via the communication means 21. The information server 20 further provides the held information to the outside.

On the other hand, the user holds the copy card 30, and only the necessary information is copied in the copy card 30 at the information server 20. The user also holds an information viewer 40. By inserting the copy card 30 into the information viewer 40, the necessary information can be viewed and heard.

The information viewer 40 may be as small as a small portable television, and the information can be viewed and heard even on a train, for example. In addition, the information center 10 can store as many information sources as possible without worrying about whether mass sales are possible. Basically, the user can use one copy card 30 repeatedly and repeatedly, and even if the copy card is expensive, the cost per information is low, which is economical.

Once the information is registered in the database at the information center 10, the information can be immediately provided to the user. Therefore, the promptness of information acquisition by the user is satisfied.

[0013]

1 is a diagram showing a first example of a system according to the present invention, and FIG. 3 is a diagram showing a second example of a system according to the present invention. In both figures, reference numbers 10, 20, 30 and 4
The components denoted by 0 are the same as those described in FIG. In the first example shown in FIG. 2, the communication means 21 in the information server 20 is associated with a network NW such as a public network, a public data network, a videotex network or an ISDN network.

The second example shown in FIG. 3 shows an example in which the communication means 21 in the information server 20 is linked with a satellite line using the satellite ST. On the other hand, the information center 10 is formed by a transmitting / receiving device and a database linked to these satellite lines and networks NW. In the figure, for simplicity, one information center 10 and one information server 2
Although 0 is shown, there are actually multiple information centers and multiple information servers 20. These information servers 2
0 may be placed in an office or a home, or may be placed in a station shop, a bookstore, or the like.

In order to perform data transfer between such a large number of information servers 20 and the information center 10, the above-mentioned first
In both the example and the second example, it is preferable to perform transmission by broadcast communication. The user who receives the information sets the copy card 30 owned by the user in the information server 20. The user chooses from a given list what information they need. Therefore, the information server 20 is provided with an information designating section 24.

As the copy card 30, it is optimum to use an IC memory card which can be miniaturized. However, in the present invention, the type of storage medium does not matter. It may be a floppy disk. In any case, any readable / writable portable storage medium may be used. It is of course possible to use a storage medium, which is considered difficult to rewrite information at present, if it can be easily rewritten in the future. For example, it is a CD-ROM or an optical memory card.

The information server 20 can be implemented in various forms. FIG. 2 and FIG. 3 show an implementation example of being installed in a stand form at a station shop or the like. Besides, it can be realized as an information access terminal. It is, so to speak, an information-only terminal. FIG. 4 is a block diagram showing an information access terminal according to the present invention, which is another implementation example of the information server 20. The information in the information center 10 designated by the user through the data input unit 55 (corresponding to the information designating unit 24) is searched by the data retrieval processing unit 56 and the line connecting unit 51 (corresponding to the communication unit 21). To be done. The retrieved information is stored in the internal memory 52 by the data processing means 54.
It is once stored in (corresponding to the buffer means 22).

The information received from the information center 10 includes
In addition to the original information, management data is also included. The management data includes billing information, information type, information date and time, and the like. These management data are separated from the original information by the data processing unit 54 and the management data extraction processing unit 57 and transferred to the external data management terminal 60. Therefore, the data transfer means 58 is provided. The external data management terminal 60 is, for example, a POS terminal placed in a store.

A copy card loading slot (card receiving portion) is provided on the right side of FIG. 4 and constitutes the above-mentioned writing means 23. The data processing means 54 writes in the specific area of the copy card whether the copy card 30 loaded in the copy card loading slot 53 is a copy card permitted to receive the information providing service. Judging from information.

Further, the data processing means 54 judges whether or not the information designated by the user via the data input section 55 exists in its own buffer means (built-in memory 52) or the external library terminal 61, and it does not exist. Only when the above mentioned search is activated. Further, the data processing means 54 uses the copy card 30 for the information retrieved from the information center 10.
When the data format does not have a predetermined data format, the format is converted into the predetermined format. A predetermined data format is commonly defined for the copy cards 30 owned by many users who use the information access terminal 50. Therefore, the built-in memory 52 stores data according to this data format. However, since there are a plurality of information centers 10 and the information thereof is diverse, the data formats are not unified. Therefore, the data in the data format unified by the data processing means 54 is stored in the built-in memory 52.

Furthermore, the data processing means 54 is a copy card 30 loaded in the write means (slot 53).
The information already recorded in (1) is temporarily saved in the buffer means (built-in memory 52), and then it is rewritten into the copy card 30 by being combined with the newly searched and transmitted information. It has been already described that the IC memory card is suitable as the copy card 30. This IC memory card is SRA
Although it can be composed of M or EPROM, it is advantageous to use EPROM because SRAM is expensive. However, EPROM cannot be partially written like SRAM. Therefore, with a copy card composed of an EPROM, when copying new information, it is not possible to search for a place where no information has been recorded yet and record the information one after another. Therefore, when the copy card 30 on which the information has already been recorded is inserted into the slot 53, the already recorded information is temporarily saved in the memory 52, merged with the new information, and then the copy card 30 is collectively processed. If the rewriting is carried out, the effect equivalent to that using the SRAM using the EPROM can be obtained.

The information access terminal 50 may include a transfer means 59. This transfer means 59 is slot 5
This is a slot for loading a copy card similar to that of No. 3. If another copy card is inserted here, the information of the copy card inserted in the slot 53 can be re-copied. The recopying operation can be performed from the data input unit 55. Copy card 30
Is just a medium for copying information, and even if there is information to be stored, it will be erased when new information is written one after another. Therefore, if it is necessary to make a storage copy card, the transfer means 59 is used.

Regarding the storage of information, the library terminal 61 can be more actively provided outside. This allows you to store more information in a smaller space. The data input unit 55 issues this storage command, the data processing unit 54 reads necessary information from the memory 52, and the library terminal 61 is accessed via the data transfer unit 58.
Send to and save.

In order to store information, the library terminal 61 as described above may be provided outside, or the memory of the exchange may be used. Generally, exchanges provide various services, and so-called mailboxes are one of the services. This utilizes the memory in the exchange. With reference to FIG. 4, reference numeral 62 denotes an exchange which accommodates the information access terminal 50, and an internal memory 63.
Write the information you want to save to. This is the data input section 55
In response to a command from the data processing means 54, the data processing means 54 reads out desired information from the memory 52, and the line connection part 51 as a communication means.
Is transmitted to the memory 63 via the.

FIG. 5 is a diagram showing another form of the information server according to the present invention. The figure shows an example of installation in parallel with an automatic ticket gate at a station. Reference numeral 71 is an automatic ticket gate type server device according to the present invention, and reference numeral 70 is an existing automatic ticket gate that processes tickets. In addition, an example of using the satellite line (FIG. 3) at three stations is shown. This automatic ticket gate type server device 71 includes a suction unit 72 for sucking the copy card 30,
The above-mentioned writing means 23 (FIG. 1) for writing predetermined information to the sucked copy card, a discharge section 73 for discharging the written copy card, and a conveyance for conveying the copy card 30 from the suction section 72 to the discharge section 73. And a section 74.

The structure other than the suction part 72, the discharge part 73 and the carrying part 74 is basically the same as the structure shown in FIG. FIG. 6 is a partial cross-sectional view of the device of FIG. In this figure, an example in which an IC memory card and a floppy disk can be used as the copy card 30 is shown, and the carrying section 74 has a carrying groove 74I corresponding to the IC memory card and a floppy disk (3.5).
Inch) corresponding transport groove 74F. Write means 23I and 23F are provided slidably on each side, and information is written while running integrally with the copy card in the transport direction.

More preferably, the normal automatic ticket gate 70 and the automatic ticket gate type server device 71 according to the present invention are shared. 7 is a flowchart (No. 1) showing an operation example of the automatic ticket gate type server device, and FIG. 8 is a flowchart (No. 2) showing an operation example of the automatic ticket gate type server device. FIG. 7 is a flowchart mainly for the automatic ticket gate function, and FIG. 8 is a flowchart mainly for the information server function. In step p in FIG. 8, it is checked whether the user can receive the information service. Step q confirms that the information already recorded and the information to be recorded are not the same.
In step r, information such as notification is written if there is enough memory. Step s is processing of data to be transferred to the external data management terminal 60 shown in FIG.

FIG. 9 is a perspective view of the entire information viewer according to the present invention. The information viewer 40 includes a driver unit 81 and a display unit 82. A display unit 83 is provided on the front surface of the display unit 82, and is composed of, for example, a liquid crystal display. The display unit 83 provides the user with character information and image information. If necessary, voice information is also output. The terminal group T provided on the side surface of the display unit 82 includes an earphone port, a video output port, a printer output port,
It represents a remote control port, etc. A power switch P is provided on the upper surface of the display unit 82. Most important to the user is the operating switch 85.

FIG. 10 is a perspective view of the driver unit shown in FIG. In the figure, the portion indicated by reference numeral 84 is the insertion slot of the copy card 30. The user listens to and listens to the information with the copy card inserted here. The driver unit 81 is provided in a plurality of types according to the medium of the copy card, but the one shown for the IC memory card is shown in the figure. Then, it is desirable that the driver unit 81 is detachable from the display unit 82. This is because the display unit 82 can share any type of copy card. So driver unit 8
The connector 8 is provided on the surface where the display unit 82 and the display unit 82 are coupled to each other.
6 is provided. The other connector to connect with this is shown in Figure 1.
Shown in 1.

FIG. 11 is a perspective view of the display unit of FIG. 9 viewed from the back. The other connector described above is indicated by reference numeral 87 in the figure. Reference numeral 88 is a battery storage portion. Thus, the connectors 86 and 87 make the driver unit 81 and the display unit 82 detachable. Figure 1
2 is a block diagram showing the basic configuration of the information viewer. The left half and the right half of the figure are a driver unit 81 and a display unit 82, respectively.

The main part in the driver unit 81 is the lead means 90. In this figure, this means 90 is connected to the drive section 91.
An example in which the reading section 92 and the reading section 92 are configured will be described. The drive unit 91 differs depending on the type of copy card, and is a disk drive device for a floppy disk. Further, the reading unit 92 is a magnetic head in this case. It also includes its amplifier circuit. On the other hand, the storage unit 93 is first provided on the display unit 82 side. This is for temporarily holding the read information from the driver unit 81 side. The control unit 94 outputs the held information to the display unit 83 in accordance with a command from the user. The command is given from the switch 85. The switch 85 is, as shown in FIG.
It is formed integrally with 2. However, a remote control operation panel (not shown) can also be used.

The control means 94 is also connected to an external interface section 95 for transmitting at least one of an image signal and an audio signal to the outside via the terminal group T. Switch 85
Mainly instructs the control means 94 to perform a selection operation for selecting information displayed on the display unit 83 according to a menu and a search operation for searching for a portion of information to be displayed.

Preferably, these operations are performed by one switch. FIG. 13 is a diagram showing a specific configuration of the switch shown in FIG. As shown in the figure, the switch 85 is a seesaw type switch and operates either one of the upper contact 87 and the lower contact 88. In the menu mode, the contact 87 is used for selection and the contact 88 is used for determination. That is, after moving the cursor displayed on the display unit 83 by the contact 87 and stopping the cursor at the desired information, the contact 88 is operated to determine the information.

On the other hand, in the scroll mode, the contact 8
7 is used for feeding, and the contact 88 is used for returning. That is, when the contact 87 is operated, the pages of the screen are sequentially advanced, and the contact 8
When 8 is operated, the pages of the screen are returned one after another. Further, in the scroll mode, there are page-based feed / return and so-called fast-forward / fast-return, and these selections are also made with one switch. A timer is used for this. The timer is built in the control means 94. That is, the clock of the CPU that constitutes the means 94 is divided into a timer. For example, if the contact 87 is intermittently operated once at a time, page feeding is performed in page units, but the duration of operating the contact 87 (time while the switch 85 is pressed) is a predetermined time (for example, 2 seconds). ), It will automatically change to fast forward. The same applies to the return contact 88.

FIG. 14 is a flowchart (No. 1) showing an operation example of the menu mode, and FIG. 15 is a flowchart (No. 2) showing an operation example of the menu mode. The "cursor" described above appears in this flowchart. This cursor movement and "input identification" on the lower side of FIG. 14 actuate the contact 87 of the switch 85 (shared with screen feed) to enter the "select" mode, and the contact 88 of the switch 85 (shared with screen return) It is operated and it becomes "decision" mode.

As shown in FIG. 12, the information viewer 40
It is battery powered and can be used outdoors (even on the train).
Therefore, the control means 94 of FIG. 12 performs at least one of the function of generating an alarm when the battery voltage is low and the automatic power-off (the power is automatically turned off after a certain period of inactivity). However, since these functions are well known, detailed description will be omitted.

Regarding this information viewer, the concrete construction of the display unit 82 will be finally shown. FIG. 16 is a diagram showing a specific example of the portion of the display unit shown in FIG. Each unit is connected to a common bus and is a CPU corresponding to the control unit 94.
The above-mentioned 96 and the LCD drive control circuit 97 are the main components. The circuit 97 controls the display unit 83 including an LCD (liquid crystal display). The storage means 93 (FIG. 12) is composed of a memory 931 and a video RAM 932. The former is used to store data, and the latter is used to store display dot data. When the display of information is interrupted and the display is continued again, the resume data indicates from which of these memories the read operation should be performed. This resume data is output from the control means 94 in FIG.

The copy card 30 may be any readable / writable portable storage medium as described above, but the data format must be unified. FIG. 17 is a diagram showing an example of the data format in the copy card. In this figure, data in areas 101 and 102 are used for information management. Area 103 is shown at the beginning of the information display. Area 104 is information that the original user wants. Specifically, the following information is registered in areas 101, 102 and 103.
