Regarding the operation of the internet terminal device 1, when the power is turned on, first, a multi-user selection screen (FIG. 4) is launched so that a plurality of people can use the internet terminal device 1. By pressing the button corresponding to the user from the selection items on the screen and then entering the password, the user logs in to the Internet terminal device 1 and shifts to the home screen which is the first screen to be activated. The home screen is a screen that is activated by pressing the home button 3 mounted on the housing, and this is usually a selection screen for a standard-installed application. When only one person is registered in the Internet terminal device and no password is set, the multi-user selection screen is not displayed and the home screen is directly displayed.

In this Internet terminal device 1,
A web browser is installed as standard, and the screen displayed when the browser is activated is called the start screen, and the system designer can set the link destination related to the web content here. As the start screen, a screen provided by the system designer or a default start screen is prepared. The former cannot be operated by the end user, but in the latter case of the default start screen, the end user can independently set a preferred link destination.

The home screen and the start screen (not the default screen) are included in the web contents on the SSFDC, or if a screen for updating is prepared in the server to which the web contents are provided, via the network. Data can be downloaded and replaced.

The home screen and the start screen can be selectively used by displaying the system name and the logo of the development company on the home screen when the power is turned on, and selecting the application on the start screen. Further, as described above, the system name and application can be selected on the home screen, and can be used to set the link to the home page desired by the user on the start screen. In addition, a characteristic system design can be performed by combining these two screens.

The basic functions of the Internet terminal device 1 include a taskbar valid / invalid function, an automatic display off function, an automatic power off function, and the like. Taskbar enabled
The disable function enables to enable / disable the task bar (Fig. 4) displayed at the bottom of the screen. It can be operated in the maintenance manager-only mode, but it is not open to general end users.

The automatic display off function sets the time setting from 0 to 0.
The display is turned off when the set time has elapsed for 60 minutes. Here, 00 disables the automatic display off function. Also, when the automatic display is off, the user is not logged off, and when returning, the original state is restored.

The auto power off function sets the time to 00.
The power supply is turned off when the set time elapses within a period of up to 60 minutes. Here, at 00, the auto power off function is disabled. At auto power off, the user is logged off.

As shown in the external view of FIG. 1, the Internet terminal device 1 is equipped with dedicated buttons 3, 4, 5 for "home", "Internet", and "mail".

The "home" button 3 is used to switch to the home screen by pressing this key in any screen state. The "Internet" button 4 moves to the browser screen that displays the last accessed URL including the locally (built-in flash memory, SSFDC) contents by pressing this key in any screen state. . When you log on and launch the browser with this key for the first time, display the start screen.
The Internet icon on the taskbar works the same as this key. The "mail" button 5 is for moving to the mail inbox by pressing this key in any screen state other than the mail screen. In addition, the LED under the button blinks when receiving mail to notify that mail is coming.

With respect to the above three buttons, when the popup operation and the soft keyboard are displayed as terminal operations, the operation of each button is invalid.

Next, the mail timer receiving function will be described.

The mail timer receives a mail from the server at every set time or every set time interval, and is operated only when the user is logged in. When the mail timer is received, the mail body is not downloaded and only the necessary header information is fetched. When a new mail is received, the LED of the mail button blinks to notify. The blinking of the mail button is stopped when the user performs "mail confirmation" in the mail inbox. An image screen of timer reception is shown in FIG.

The maximum receivable mail size when receiving a mail is the sum of the size of the mail body and the attached file on the server. Settable range of this size is 0
When X is set to X (KB) (X is the capacity of the built-in flash), when "0" is set, the size of the attached file is not limited. In addition, the maximum reception size of the mail body can be set separately on the terminal. This size is Y (KB)
When (Y <X), when the maximum received mail size <Y (KB) is set on the setting screen, the maximum received mail size is the maximum received size of the mail body. If the body of the email exceeds the maximum reception size of the body of the email, the portion after the maximum reception size of the body of the email is truncated, and information notifying that it has been truncated is added to the end of the body of the email. If the total size of the email body and attached file exceeds the maximum email reception size, the attached file is not received. If the attached file cannot be received because the maximum mail reception size is exceeded, the attached file information that is not received is added to the end of the body of the email.

As an external input device, a numeric keyboard and a bar code reader are used by connecting them to the PS / 2 interface section 117 attached to the main body. An input image when using the numeric keyboard and the barcode reader is as shown in FIG. Input from these external input devices is HTM
Use the L application. Display the input guideline on the bottom line (task bar) of the screen, read the data from the barcode reader, and write the data in the guideline section.
If necessary, if you need to enter the quantity, touch the numeric keypad on the lower right to display the soft numeric keyboard input line and enter the numeric value. This is a numerical value input means when only the bar code reader is attached, and when the hardware numeric keyboard is attached, it is not used and input from the numeric key board.

In this Internet terminal device, the SSFD of three types of formats is used as an external storage device according to the use.
C (original SSFDC (original smart media), extended SSFDC (extended smart media), digital camera SSFDC (digital camera smart media) is used.

The characteristics of each SSFDC are as follows.

The original SSFDC is an SSFDC initialized exclusively for this terminal, and only one sheet can be used (only one sheet can be used) for each Internet terminal device. With this SSFDC inserted, it is possible to use the functions of all standard-installed applications.

The extended SSFDC is an SSFDC for use for Web contents, and a plurality of sheets can be replaced and used. With the extended SSFDC inserted, only some of the functions of the applications installed as standard on this terminal can be used. For example, a copy of a web screen and web content. In particular, when the extended SSFDC is made to correspond to each Web content and the content is desired to be used, the fixed (corresponding) extended SS is used.
FDC can be inserted and used. As a usage image,
The extended SSFDC is inserted so that the specific Web contents are used like the cassette type game software of the video game is used.

The digital camera SSFDC is a DCF (Design r
ule for Camera File system) This is an SSFDC for digital cameras that conforms to the standard, and is usually used for digital cameras, and when sending digital camera data by attaching it from this terminal to an email or saving camera data in the terminal. , Insert and use.

Next, the initialization of the original SSFDC will be described.

The volume label in the SSFDC is, for example, 'IP-8000SM', and the original SSFDC identification file name in the SSFDC is'IP8000I.
D '. The file contents of "IP8000ID" are
"Main program version name" CRLF and "original SM_ID" CRLF. Original SM_ID
As for, the date & time at the time of initialization and the user name are created and written.

For example, the main program version name:
Date & time when initialized with 1.02: 2001 8
29th, 18:10:30, User name: tokazu
1.02 [CRLF] 20010 when initialized by
829181030 tokazu [CRLF] and IP-
It is written in the 8000 ID file.

At this time, the same original SM_ID with a maximum of 24 characters is to be stored in the flash memory 109 built in the Internet terminal device 1, and S
At the same time when the SFDC is initialized, the data in this flash memory is also updated. As a result, one original SSFDC and the present Internet terminal device 1 have a one-to-one correspondence when the SSFDC is initialized.

In SSFDC, the standard application directory uses the directory name "U" for every n users.
It is created with SER0 "to" USERn. "The user release directory is created with the directory name" EXIP8000 ", for example.

Here, the original SSFDC and other SSs
The method of discriminating the FDC is that the original SSFDC says, "The volume label is" IP-8000SM ", the file" IP-8000ID "exists in the root directory, and the content matches the original SM_ID on the main body flash memory. It is.

In the standard-installed application, the data that can be used by the original SSFDC is a screen memo list that is a list of screens saved at the time of Web browsing, a screen memo that is the data of the screen itself, and a mail function in the Internet function. An attachment file list that is a list of attachment files attached to one email, a database of attachment files themselves, attachment file names, and other storage data in a storage for storing music and the like, storage file name database. There are also melody original data and drawing data.

Next, a method of discriminating the digital camera SSFDC will be described below.

A file that meets all the following conditions (1) to (4) is discriminated as a DCF basic file.

(1) DCF image root directory'DCIM 'directly under the root directory of SSFDC
Must be under a directory.

(2) DCF directory The directory is located below the DCF image root directory of (1) above. The directory name is fixed at 8 characters. The 1st to 3rd characters are numbers from '100' to '999'. (Directory number) *: Missing number is allowed The number of characters following the above directory number is 5 characters.
(Free characters of DCF directory name) (3) DCF file name It is in the DCF directory of (2) above and has the following file name. The file name is fixed at 8 characters. The 1st to 4th characters are any one-byte alphanumeric capital letters.
(Free characters in DCF file name) The 5th-8th characters are '0001' ~ '9999'
Is the number. (File number) *: Missing number extension is fixed to "JPG".

(4) DCF basic file Having the DCF file name of (3) above, the following DCF basic file discrimination information in the file matches. "Compatibility identification index (Interoperabi
“Rity Index)” is “R98”. "Compatible version (Interoperability
y Version) "is" 0100 ".

The Internet terminal device 1 executes a specific program module in the terminal to execute SSFDC.
It inputs and outputs data to and from it, and downloads from the Internet and uploads to the Internet. This program module is a CGI [Common Gateway In] operating on a Web server.
interface]. The difference is that this program module runs in the terminal, CG
I is to run on the server.

In this Internet terminal device 1, when this program module is operated, a pop-up screen is displayed to confirm the execution. At that time, the pop-up display of the confirmation is controlled by two types of flags, that is, a valid flag for use confirmation and a usable flag, depending on the purpose. The control content is shown in FIG. 6, and the popup display content is shown in FIG. Here, the valid flag for use confirmation is a flag that is used because the system developer can handle it because it is necessary to display a popup, and the usable flag is 1 for popup.
This is a flag operated by the terminal itself so as not to be issued for the second time and after after being issued again.

As shown in the control flow chart of FIG.
First, it is determined whether the use confirmation pop-up of the specific program module is valid (step, hereinafter, step is referred to as S, the same in the drawings), if it is valid, the pop-up is displayed (S2), and if it is executed, the program is executed (S
3) If not, that effect is displayed and the process ends (S4).

Returning to S1, if the use confirmation pop-up of the specific program module is invalid (S1) and the usable flag is ON (meaning that it has been displayed once) (S5), the pop-up of the specific program module is displayed without displaying the pop-up. Execute (S3). If the usable flag is OFF, a confirmation pop-up is displayed (S6), and if it is executed, the usable flag is made usable (S7) and the program is executed (S3). If it is not executed, that effect is displayed and the process ends (S4).

As an example of the specific program module, S

Next, an operation example in the case where a specific program module is installed in the Internet terminal device 1 as a dedicated system and a practical example of Web contents using the entire system will be described. Let me explain using an example.

The specific program module for realizing the dedicated system such as the inventory management, pet hospital, learning test system, etc. is stored in the SSFDC 20. As a result, the user carries only the SSFDC 20 and sends the SSFDC 2 to the other Internet terminal device 1.
By connecting 0, the specific program module can be used.

Further, the user downloads the specific program module from the server 30 or the server of the system maker to the SSFDC 20, or distributes the SSFDC 20 in which the specific program module is written in advance from the system maker or an authorized provider. Receiving the specific program module.

<Inventory Management Case> With respect to the case of inventory management, the flow of processing of the inventory management system using this Internet terminal device will be described below with reference to FIGS.

(1) About file output to SSFDC The input display unit 2 of the Internet terminal device 1 displays a screen as shown in FIG. This display screen is SSFDC
It is created based on the HTML format file stored in the SSFDC connected to the slot 111. When the code name, quantity, and remarks of the inventory parts are input on this screen and the completion button is pressed, each data is stored in the SSFDC inserted in this terminal in CSV format, for example.

(2) File data input from SSFDC Insert the inventory data (code name, quantity, remarks) in SSFDC into the screen viewed by the browser. As the screen, it is possible to display all the code names in stock, or to display the quantity, the remarks, and many other information not included in the items in FIG. 9 for one specific code name in one page.

(3) Uploading to network Write the data in SSFDC to the database of the server on the Internet. For example, the order information is uploaded, the inventory data in the database is changed, and the order receiving routine on the server side starts.
