DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to information for designating a predetermined portion of a screen displayed on a device to which information based on optical information is input or transmitted, information for moving a position designation section to a specific position, and position designation. The present invention relates to optical information including information for generating a display unit, a mobile terminal that converts a command signal suitable for the device, a system using the mobile terminal, and an operation procedure of an external device. .

[0002]

2. Description of the Related Art Conventionally, a device to which a portable terminal typified by a portable telephone having a network connection / browsing function such as the Internet is connected is used for warehouse inventory management and ordering. I have. At this time, the server connected by using the mobile phone has a function of authenticating the connected user and displaying current stock information, order information, and the like to the mobile phone. In a system using a mobile phone and a server, a mobile terminal for data input may be connected to the mobile phone in order to save input work. For example, by reading optical information such as a barcode with a portable terminal for data input, data of a product code is inputted to a portable telephone. The mobile phone acquires inventory information, product-related data, and the like regarding the product code stored in the server via the Internet and displays the information on the screen. Further, the server has a function of registering a product code transmitted via a mobile phone as sales data in a database.

[0003]

However, in a system using a mobile phone with an Internet connection / browsing function,
In order to realize different processes on the server side, it is necessary to prepare a plurality of server connection information (hereinafter simply referred to as URL) and access a different URL for each process.

Similarly, since the displayable range of the display unit and the number of expressible colors differ depending on the type of external device represented by a mobile phone having an Internet connection / browsing function, a plurality of URLs are prepared on the server side. It is necessary to access a URL suitable for the model of the user from an external device.

[0005] In a conventional system, access to a predetermined URL is realized by reading the URL as optical information with a portable terminal. Or, a conventional system has been implemented in which a user judges an external device and performs an access operation to a suitable URL.

However, when a URL is converted into optical information, the URL becomes
Since the information amount is relatively large, a bar code or the like, which is a typical example of optical information, becomes long horizontally, and there is a problem that it cannot be read by a conventional reading device. In addition, when the user makes a determination on an external device, this may cause a determination error or an increase in operation load, and there is a problem that the user has poor usability of the system.

[0007] There are a plurality of types of mobile phones with an Internet connection / browsing function used in the above-mentioned system in the market, and the operation procedure differs for each manufacturer. The procedure for using the Internet is also different for each model. It is necessary to connect a mobile terminal to multiple types of mobile phones, but since the operation procedure differs for each type of external device, it is necessary for the system user to prepare a mobile terminal suitable for the type of mobile phone to be connected was there. However, there is a problem that this method cannot cope with a change in a mobile phone used in the system.

[0008] In the above system, optical information obtained by an external device is transmitted from a portable terminal, and data is transmitted to a server via a portable telephone. However, when optical information is read by the mobile terminal while the communication means connecting the mobile terminal and the external device is logically disconnected, the data is not transmitted to the external device. For this reason, there is a problem that the user intends to read the optical information but has not transmitted it to the external device.

In the above system, the operation procedure of the external device is transmitted from the portable terminal to the external device to access the server.
However, when the operation procedure is started, the mobile terminal may perform an unintended operation when the position designation display unit of the external device is located at a position different from the initial position.

In the above system, there are cases where it is desired to switch the mode of the portable terminal to operate. For example, there is a case in which temporarily read optical information is stored in a memory of a mobile terminal, and after the number of data reaches a certain number, the read optical information is transmitted to an external device.

At this time, the user of the system switches the mode of the portable terminal by key operation or the like, temporarily sets the mode to the memory storage mode, reads optical information, and transmits data after the number of data reaches a certain number. There is a method such as switching to a mode. However, an error occurs when performing the switching operation and the procedure, and the switching operation itself burdens the user.

In a system using a portable terminal and an external device, a system designer generally creates optical information used in the system. Therefore, optical information including movement information of the position designation display unit and the like can be created, and the operation of the external device can be performed efficiently. However, optical information such as JAN code, which exists in many markets, includes:
The operation of the external device cannot be added as optical information. For this reason, when market optical information is used in the above system, the user has to operate an external device in order to perform data input operation. For this reason, there has been a problem that a burden is imposed on the user, for example, the user needs to be skilled in operating the external device.

In the above system, screen information provided from a server is displayed on a display unit of an external device, and a portable terminal is used for data input to the screen. If there are a plurality of input items on the screen, optical information of the movement information of the position designation display unit is read, and after the position designation display unit is moved to a predetermined position, data input is performed. If the screen information provided from the server to the external device does not fit on one screen, a scroll operation for moving the screen up and down is performed. At this time, since the external device uses the movement information of the position designation display unit to realize the downward scroll, the movement information of the position designation display unit which has been prepared in the optical information which has already been prepared indicates the position intended by the portable terminal. There is a problem that the moving amount of the designated display unit may not be obtained.

In the above system, when there are a plurality of input items on the screen provided from the server, it is necessary for the portable terminal to calculate and hold the movement amount of the position designation display unit up to the special link information. However, the screen of the server is frequently changed, and it is necessary to change the calculation processing of the movement amount of the position designation display unit on the mobile terminal side each time. For this reason,
There were problems such as the inability to flexibly change the screen on the server side.

In the above system, when unnecessary optical information is read due to a user's mistake while a screen provided from the server is displayed on an external device, a transition to an unintended server-side screen may occur. This is because optical information represented by a JAN code or the like generally includes many numbers, and a screen provided from the server side includes a lot of link information using the numbers as an access key. .
An access key is, for example, when the number "1" is pressed,
A process for calling a screen corresponding to the number to an external device is performed.

Here, an access procedure to the server 23 is shown as an example. In order to access the server 23, it is necessary to call a URL input screen to the external device 22. FIG. 4 shows an operation procedure for that.

Here, according to FIG. 4, the TYPE-type described in column No. 1 is determined by a program stored in advance.
If A is selected, the procedure for accessing the server is "↑
Wait for decision time ↓ → Decision decision ”. The arrow on the access procedure indicates the moving direction of the cursor.

As described above, the operation procedure of the external device is held in the mobile terminal and switched by setting, so that the mobile terminal which had to be purchased for each model of the external device in the past is one.
This can be supported by the model, and the convenience for the system user can be improved.

As one embodiment of the invention according to the third and fourth aspects, the URL corresponding to the model of the external device to be connected is stored in the memory unit as shown in FIG. The mobile terminal determines the model of the external device according to the flowchart shown in FIG.

The following processing is performed in one processing when the portable terminal is activated. The portable terminal transmits a model identification command to the external device (STEP 1), and the external device responds to the portable terminal (STEP 2). The mobile terminal analyzes the response from the external device to determine the model name (STEP 3), and stores the model name in the memory unit (STEP 4).

FIG. 7 shows a specific process for connecting to the server. The mobile terminal acquires the model name from the memory unit (S
(Step 5), a URL corresponding to the model is obtained from the memory unit (STEP 6). The operation procedure corresponding to the model is acquired from the memory unit (STEP 7), and the operation procedure and the URL acquired from the memory unit are transmitted to the external device (STEP 8).

Here, in the examples shown in FIGS. 4 and 5, UR is selected when model TYPE-A is connected.
L and how the operating procedure is selected.

When the model is determined, the URL corresponding to the model is determined.
Is selected. Here, TYPE described in column No. 1 in FIG.
If URL -A is connected, URL http: // w
ww. dummy. jp / TYPE-A. htm is selected.

Similarly, when the model is determined, an operation procedure according to the model is selected. Here, when the TYPE-A described in the column No. 1 in FIG. 4 is connected, the procedure for accessing the server is as follows: “決定 wait for the decision time ↓ → decide to decide”
Becomes

The connection to the server in the above procedure can reduce the burden of setting the external device on the user, and the external device to be connected can be changed even when the external device used in the system is changed. Just by changing, the mobile terminal can automatically recognize the external device and change the URL to be transmitted and the operation procedure.

After transmitting a specific key operation to the external device for the purpose of returning the position designation display section of the external device such as a mobile phone to the initial state, transmission of a predetermined key operation is started. As the specific key in this case, for a mobile phone with an Internet connection / browsing function, an on-hook key is pressed.

The invention described in claim 7 shows a method of selecting a specific menu on a menu selection screen of an external device typified by a mobile phone with an Internet connection / browsing function. FIG. 8 is an example of a menu selection screen of the external device.

Here, nine menu items are arranged on one screen. The cursor indicates one of the nine menu items, and the initial position is the position 2-2 in FIG.

The cursor is moved by arrow keys arranged on the keyboard of the external device. When the left arrow key is pressed when the position designation display section is located at 2-2, the position designation display section becomes 2-
Move to position 1. Even if the left arrow key is pressed again while the position designation display section is at 2-1, the position of the position designation display section remains 2-1 because there is no menu item on the left side of 2-1. Similarly, if the up arrow key is pressed while the position designation display section is at the position 1-1, the position of the position designation display section is 1-
It remains at 1.

For example, when the access processing to the server is arranged in the menu 1-2, the menu initial position (2-
To move from 2) to menu 1-2, the up arrow key may be pressed once.

Here, the position of the position designation display section when the portable terminal is connected is unknown. For example, when the position designation display section is located at the position 3-2, even if the up arrow key is pressed once, it is impossible to move to the position 1-2 where the server access processing is arranged.

Regardless of the position of the position designation display section 1-1 to 3-3, the left arrow key is pressed twice, and the up arrow key is pressed twice, as a procedure capable of always accessing the server. After moving the position designation display section to 1-1, the specified menu can be accessed regardless of the position of the position designation display section by performing a predetermined key operation or a right arrow key in the case of a server access process. It is.

Therefore, by using the above method when selecting a predetermined menu of the external device from the portable terminal by transmitting a key operation, a predetermined menu item can be selected regardless of the state of the position designation display section of the external device. It is possible to do.

FIG. 9 is a flowchart showing one embodiment of the eighth and ninth aspects. Two types of input labels and output labels are prepared as optical information for switching the operation of the mobile terminal.

First, optical information is read by the portable terminal (STEP 9), and it is determined whether the optical information is an input label (STEP 10). If the read optical information is an input label, the operation mode of the portable terminal is switched to the input mode (STEP 13). Next, if it is not an input label, it is determined whether it is an output label (STEP 1).
1) If the read optical information is an output label, the data stored in the internal memory of the portable terminal is transmitted to an external device (STEP 14). If it is not the output label, it is determined whether or not the mode of the portable terminal is currently the input mode (STEP 12). If it is the current input mode, the data of the read optical information is written into the memory unit (ST12).
EP15). If it is not in the input mode, the current read data is transmitted to the external device (STEP 16).

FIG. 10 is a flowchart showing one embodiment of the tenth aspect of the present invention. This flowchart describes transmission processing when optical information is read by a portable terminal and the read data is transmitted.

First, the data of the read optical information is compared with the information in the memory (STEP 17), and it is determined whether they are the same (STEP 18). In the case of the same, the operation information of the external device is set before and after the read data (STE
P19). Next, data is transmitted to the external device (STE
P20).

As an example of the operation information of the external device set in STEP 19, there is a "decision" key or the like present on the keyboard of the external device.

FIG. 11 shows an example of a screen displayed on the display unit of the external device. Here, a portion indicated by a broken line indicates a range in which scrolling is required when the down arrow key of the external device is pressed.

In the system according to the present embodiment, by reading optical information with a portable terminal connected to an external device, the same operation as when a key of the external device is operated can be obtained. After inputting the order quantity, which is an input item in FIG. 11, the down arrow key is read once to read the optical information in order to perform transmission processing. Normally, the position designation display part moves down one position and moves to the transmission position,
In the screen requiring scrolling shown in FIG. 11, the down arrow key is determined to be scroll processing by the external device, and therefore the position designation display unit does not move to the transmission position.

In the system according to the present embodiment,
For the purpose of avoiding such characteristics of the external device, a screen provided from the server side to the external device is stored in one screen.

When using the portable terminal, if there are a plurality of input items on the screen of the external device, the external device has a special meaning such as "transmit" or "cancel" by grasping the current input position. The movement information of the position designation display section up to the link destination was calculated. Therefore, it is necessary to change the software of the mobile terminal in accordance with the change of the screen configuration and input items on the server side.

FIG. 12 is a view showing an embodiment of a screen in which link destinations having special meanings are arranged at the top and bottom of the screen for the purpose of solving the above-mentioned problem.

Three input items are arranged on the screen, and the position designation display section is located at any one of them. It is necessary to select the link destination 1 and the link destination 2 at an arbitrary position. The link destination 1 is arranged at the top of the screen, and the link destination 2 is arranged at the bottom.

When moving the position designation display section to the link destination 1, "three times of upward movement information of the position designation display section" is prepared as optical information and read by a portable terminal to display the position designation display. The part can be moved to the link destination 1. When the position designation display section is moved to the link destination 2, the optical information is "movement information of the position designation display section in three downward directions".
Is prepared and read by a mobile terminal.

This method is characterized by the fact that even if the position designation display section is moved three times upward at the position of the input item 1, unnecessary movement information of the position designation display section for two times is ignored. It was used.

FIG. 13 shows an embodiment of a screen in which a special link destination is arranged for a specific character. Link information 1, link information 2, and link information 3 are arranged on the screen. Data entry items do not exist on the screen.

When the position designation display section is moved on the external device and the enter button is pressed on the link information, a screen of the URL set in the link information is displayed. Similarly, a key on the keyboard of the external device can be assigned to the link information. For example, it is common to assign a number “1” on the keyboard to link information 2 and a number “2” to link information 3. Here, by pressing the numeral “1” on the keyboard, a screen of the URL set in the link information 2 is displayed on the external device.

However, on the screen shown in FIG. 13, when the user reads optical information due to an operation error of the portable terminal and erroneous numeric data is input on this screen, the link information 2 or Was assigned,
A URL screen not intended by the user is displayed.

If the user erroneously reads the optical information including the enter key as the information while the position designation display section is in the link information 2, the URL screen of the link information 2 is displayed.

For the purpose of preventing the above problem, it is assumed that the link information 1 is set to its own URL information on the screen shown in FIG. 13, and that the initial position of the position designation display section is in the link information 1. In addition, symbols such as “*” and “#” are assigned to the link information 2 and the link information 3 instead of the numbers generally used conventionally.

The data generally included in the barcode is a numeral, and the characters “*” and “#” are rare.
Therefore, by using the screen provided from the server side in this configuration, the current screen can be continuously displayed even if the user has read unintended optical information due to an operation error.

Further, the present embodiment is realized by a program, and is recorded on a recording medium such as a floppy disk and transferred, so that it can be easily implemented by another independent computer system. FIG. 7 is a diagram for explaining a case where this is carried out using a floppy disk.

FIG. 14A is a diagram showing an example of a physical format of a floppy (registered trademark) disk as a recording medium. A track is formed concentrically from the outer circumference to the inner circumference, and is divided into 16 sectors in the angular direction. The program is recorded according to the allocated area.

FIG. 14B is a diagram for explaining a case for storing the floppy disk. From the left, a front view of the floppy disk case, a sectional view thereof, and a floppy disk are shown. By storing the floppy disk in the floppy disk case in this way, the floppy disk can be protected from dust and external impact and can be transported safely.

FIG. 14C is a diagram for explaining recording and reproduction of a program on a floppy disk. By connecting a floppy disk drive to the computer system as shown in the figure, it becomes possible to record and reproduce programs on the floppy disk. A floppy disk is incorporated into and removed from a floppy disk drive through a floppy insertion slot. When recording, a program is recorded from a computer system to a floppy disk by a floppy disk drive. For playback, the floppy disk drive reads the program from the floppy disk and transfers it to the computer system.
