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 part of a screen displayed on a device to which information based on optical information is input or transmitted, information for moving a position designating part to a specific position, and position designating. The present invention relates to optical information including information for generating a display unit, a mobile terminal for converting into 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 connected to a mobile terminal typified by a mobile phone having a network connection / browsing function such as the Internet has been used for management of warehouse inventory and ordering work. There is. At this time, the server connected using the mobile phone has the functions of authenticating the connected user and displaying the current inventory information, order information, etc. on the mobile phone. In this system using a mobile phone and a server, a mobile terminal for data input may be connected to the mobile phone for the purpose of saving the input work. For example, data of a product code is input to a mobile phone by reading optical information such as a barcode with a mobile terminal for data input. The mobile phone acquires inventory information about product codes, product-related data, etc. stored in the server via the Internet and displays them on the screen. In addition, the server has a function of registering the product code transmitted via the mobile phone in the database as sales data.

[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 different URLs for each process.

Similarly, since the displayable range of the display unit and the number of expressible colors are different depending on the model of the external device represented by the mobile phone with Internet connection / browsing function, a plurality of URLs are prepared on the server side. , You need to access the URL that matches your model from an external device.

In a conventional system, a URL is used as optical information and is read by a mobile terminal to realize access to a predetermined URL. Alternatively, a conventional system has been used in which a user judges an external device and performs an access operation to a suitable URL.

However, if the URL is converted into optical information, the URL
Since there is a relatively large amount of information, there is a problem in that a barcode or the like, which is a typical example of optical information, becomes laterally long and cannot be read by a conventional reading device. Further, when the user makes a judgment of the external device, it causes a mistake in judgment and an increase in operation load, and there is a problem that the usability of the system is poor for the user.

In addition, there are a plurality of types of mobile phones with Internet connection / browsing functions used in the above-mentioned system on the market, and the operating procedures differ for each manufacturer. The procedure for using the Internet also differs for each model. It is necessary to connect the mobile terminal to multiple types of mobile phones, but the operation procedure differs depending on the model of the external device, so it is necessary to have the system user prepare a mobile terminal compatible with the model of the mobile phone to be connected. was there. However, this method has a problem in that it cannot respond when the mobile phone used in the system is changed.

[0008] In the above system, the portable terminal transmits the optical information obtained by the external device, and the data is transmitted to the server via the 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. Therefore, there is a problem that the user intends to read the optical information, but the information is not transmitted to the external device.

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

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

At this time, the system user switches the mode of the portable terminal by a key operation or the like to temporarily set the memory storage mode, then reads the optical information and transmits the data after the number of data reaches a certain number. There are methods such as switching to the mode. However, an error occurs when performing this switching operation or procedure, and the switching operation itself becomes a burden on 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, it is possible to create optical information including movement information of the position designation display unit and to efficiently operate the external device. However, there are many optical information in the market, such as JAN code,
The operation of the external device cannot be added as optical information. Therefore, when using optical information on the market in the above system, the user has to operate an external device in order to perform the data input operation. For this reason, there has been a problem that the user needs to be skilled in operating the external device, which places a burden on the user.

In the above system, the screen information provided from the server is displayed on the display unit of the external device, and the portable terminal is used to input data to the screen. If there are a plurality of input items on the screen, the movement information of the position designation display unit converted into optical information is read, and the data is input after moving the position designation display unit to a predetermined position. 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 already been prepared as an optical information indicates the position intended by the mobile terminal. There is a problem that the movement 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 by the server, it is necessary for the mobile terminal to calculate and hold the amount of movement of the position designation display unit to the special link information. However, the screen of the server may be changed frequently, and it is necessary to change the calculation processing of the movement amount of the position designation display unit on the portable terminal side each time. For this reason,
There was a problem that the screen on the server side could not be changed flexibly.

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

It is an object of the present invention to improve the work efficiency by making it possible to easily and accurately use a portable terminal and an external device connected to the portable terminal.

[0017]

In order to achieve the above object, the following means are provided. The invention according to claim 1 is a detection unit that detects reflected light from optical information, and a conversion unit that converts the optical information detected by the detection unit into a code represented by the optical information. A server corresponding to the read optical information by having a memory unit provided to store one or a plurality of server connection information and reading the optical information corresponding to the server connection information stored in the memory unit. The mobile terminal is characterized by converting connection information and an operation procedure for the connection into a command signal suitable for an external device and transmitting the command signal.

According to a second aspect of the present invention, there is provided a detecting section for detecting reflected light from the optical information, and a conversion for converting the optical information detected by the detecting section into a code represented by the optical information. Section, a memory section capable of storing one or a plurality of server connection information, and optical information corresponding to the server connection information stored in the memory section are read to correspond to the read optical information. A portable terminal including a server connection information and an operation procedure for the connection converted into a command signal suitable for an external device and transmitting the command signal; an external device that receives a signal from the portable terminal; A mobile terminal system including a server connected to a device.

A case where the optical information 11 is read and compared with the code stored in the memory section shown in FIG. 3 will be described. When the content of the read optical information is “panasonic” shown in the number 1 column, h is set as the corresponding URL among the URLs stored in the memory unit 14.
ttp: www. matusita. co. jp / is selected by an instruction from the control means 13. External device 22
Is transmitted with the corresponding URL and the operation procedure for accessing the URL.

Further, as shown in FIG. 4, the access procedure corresponding to the model of the external device 22 to be connected is stored in the memory section. When a model is selected by inputting quantity information or the like by key operation or reading optical information, the corresponding operation procedure is called.

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

According to FIG. 4, the TYPE-indicated in the column No. 1 by the program stored in advance.
When A is selected, the procedure for accessing the server is "↑
Waiting for decision time ↓ → decision decision ”. The arrow on the access procedure means 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 the setting, so that the mobile terminal which has conventionally been required to be purchased for each model of the external device is one.
It can be supported by the model, and the convenience of the system user can be improved.

As an embodiment of the invention described in claims 3 and 4, 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 mobile terminal is activated. The mobile terminal sends a model identification command to the external device (STEP 1), and the external device responds to the mobile device (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 when connecting to the server. The mobile terminal acquires the model name from the memory unit (S
TEP5), the URL corresponding to the model is acquired from the memory unit (STEP6). Further, the operation procedure corresponding to the model is acquired from the memory section (STEP 7), and the operation procedure and the URL acquired from the memory section are transmitted to the external device (STEP 8).

The UR selected when the model TYPE-A is connected in the example shown in FIGS. 4 and 5.
It shows how L and the operating procedure are selected.

When the model is determined, the URL corresponding to the model
Is selected. TYPE shown in FIG. 5, column 1
-When A is connected, the URL http: // w
ww. dummy. jp / TYPE-A. htm is selected.

Similarly, when the model is determined, the operation procedure corresponding to the model is selected. Here, when the TYPE-A described in the number 1 column in FIG. 4 is connected, the access procedure to the server is "↑ wait for decision time ↓ → decide decision".
Becomes

By connecting to the server according to the above procedure, the burden of setting the external device on the user can be reduced, and even if the external device used in the system is changed, the external device to be connected is changed. The mobile terminal can automatically recognize the external device and change the URL to be transmitted and the operation procedure only by changing the change.

Further, after transmitting a specific key operation to the external device for the purpose of returning the position designation display portion of the external device such as a mobile phone to the initial state, a predetermined key operation is started to be transmitted. As a specific key in this case, there is a press of an on-hook key in a mobile phone with an Internet connection / browsing function.

The invention according to claim 7 shows a method of selecting a specific menu on a menu selection screen of an external device represented 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 the arrow keys arranged on the keyboard of the external device. If 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 when the position designation display unit is at 2-1, there is no menu item on the left side of 2-1 and the position of the position designation display unit remains at 2-1. Similarly, if the up arrow key is pressed when the position designation display portion is at the position 1-1, the position of the position designation display portion is 1-
It remains 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, press the up arrow key once.

Here, the position of the position designation display portion when the portable terminal is connected is unknown. For example, when the position designation display portion is located at the position 3-2, even if the up arrow key is pressed once, it is not possible to move to the position 1-2 where the access processing to the server is arranged.

The left arrow key is pressed twice and the up arrow key is pressed twice as a procedure for always being able to access the server regardless of the position of the position designation display section 1-1 to 3-3. After moving the position specification display section to 1-1, by pressing the right arrow key in the case of predetermined key operation, server access processing, you can access the predetermined menu regardless of the position of the position specification display section Is.

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

FIG. 9 is a flowchart showing an embodiment of claims 8 and 9. Two types of input labels and output labels are prepared as optical information for switching the operation of the mobile terminal.

First, the optical information is read by the portable terminal (STEP 9), and it is determined whether the optical information is the input label (STEP 10). When the read optical information is the input label, the operation mode of the mobile terminal is switched to the input mode (STEP 13). Next, if it is not an input label, it is judged whether it is an output label (STEP1
1) If the read optical information is an output label, the data stored in the internal memory of the mobile terminal is transmitted to the external device (STEP 14). If it is not an output label, it is determined whether or not the mode of the mobile terminal is currently the input mode (STEP 12), and if it is the current input mode, the read optical information data is written in the memory section (ST).
EP15). If it is not in the input mode, the read data of this time is transmitted to the external device (STEP 16).

FIG. 10 is a flow chart showing one embodiment of the invention of claim 10. This flowchart describes the transmission process when the optical information is read by the mobile terminal and the read data is transmitted.

First, the read optical information data is compared with the information in the memory (STEP 17), and it is determined whether they are the same (STEP 18). If the same, set the operation information of the external device before and after the read data (STE
P19). Next, the 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 "OK" key or the like existing on the keyboard of the external device.

FIG. 11 is an example of a screen displayed on the display unit of the external device. Here, the portion shown by the broken line represents a range in which scrolling is required by pressing the down arrow key of the external device.

In the system according to the present embodiment, by reading the optical information with the portable terminal connected to the external device, the same operation as when the key of the external device is operated can be obtained. After the order quantity, which is an input item in FIG. 11, is input, the optical information stored is read once with the down arrow key for transmission processing. Normally, the position designation display unit moves down one position and moves to the transmission position,
On 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.

Further, in the system according to this embodiment,
In order to avoid such a feature of the external device, the screen provided to the external device from the server side is contained in one screen.

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

FIG. 12 is a diagram showing an embodiment of a screen in which link destinations having a special meaning are arranged at the top and bottom of the screen for the purpose of solving the above problems.

Three input items are arranged on the screen, and the position designation display portion is located at any one of them. Further, it is necessary to select the link destination 1 and the link destination 2 at arbitrary positions. A link destination 1 is arranged at the top of the screen, and a link destination 2 is arranged at the bottom.

When the position designation display unit is moved to the link destination 1, "three times upward movement information of the position designation display unit" is prepared as optical information, and the position designation display is performed by reading it with the portable terminal. The part can be moved to the link destination 1. When the position designation display unit is moved to the link destination 2, the optical information is “three times downward movement information of the position designation display unit”.
It can be realized by preparing and reading with a mobile terminal.

According to this method, even if the position designation display portion is moved upward three times at the position of the input item 1, unnecessary movement information of the position designation display portion for two times is ignored. It was used.

FIG. 13 shows an example of a screen in which a special link destination is arranged on a specific character. Link information 1, link information 2, and link information 3 are arranged on the screen. Data input item does 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, the 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 the number "1" on the keyboard to the link information 2 and the number "2" to the link information 3. By pressing the number "1" on the keyboard, the screen of the URL set in the link information 2 is displayed on the external device.

However, in the screen shown in FIG. 13, when optical information is read by the user's operation error of the portable terminal and incorrect numerical data is input on this screen, the numerical information is added to the link information 2 or the link information 3. Was assigned,
The screen of the URL not intended by the user is displayed.

If the user mistakenly reads the optical information including the enter key as information in the state where the position designation display portion is in the link information 2, the screen of the URL of the link information 2 is displayed.

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

The data generally contained in the bar code is a numeral, and the characters "*" and "#" are rare.
Therefore, with the screen provided from the server side having this configuration, the current screen can be continuously displayed even if the user reads unintended optical information due to an operation error.

The portable telephone of this embodiment is realized by a program, and by recording this on a recording medium such as a floppy (registered trademark) disk and transferring it, it can be easily carried out by another independent computer system. Figure 7
FIG. 6 is a diagram for explaining a case where this is performed with a floppy disk.

FIG. 14A is a diagram showing an example of a physical format of a floppy disk which is a recording medium. Tracks are concentrically formed from the outer circumference toward the inner circumference, and are divided into 16 sectors in the angular direction. The program is recorded according to the area thus allocated.

FIG. 14B is a diagram for explaining a case for accommodating this floppy disk. From the left, the front view of the floppy disk case, its cross-sectional view, and the floppy disk are shown, respectively. By storing the floppy disk in the floppy disk case in this way, the floppy disk can be protected from dust and external shocks and safely transferred.

FIG. 14C is a diagram for explaining the recording and reproduction of the program on the floppy disk. By connecting a floppy disk drive to the computer system as shown in the figure, it becomes possible to record and reproduce the program on the floppy disk. The floppy disk is inserted into and removed from the floppy disk drive through the floppy insertion slot. When recording, the 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.

In this embodiment, the description has been given by using the floppy disk as the recording medium.
The same can be done using an optical disc. Further, the recording medium is not limited to these, and any other medium such as an IC card and a ROM cassette capable of recording the program can be similarly implemented. Furthermore, through the Internet,
It is also possible to provide a program.

According to the embodiment of the present invention, it is possible to provide means for easily accessing a plurality of URLs with one portable terminal, which has been a problem in the past. Further, when connecting to different types of external devices, one type of mobile terminal can be used so that the user does not have to perform unnecessary setting work. It is possible to solve the problem of the system due to a setting error, which has been a problem in the past, and to significantly reduce the burden on the user.

Further, according to the embodiment of the present invention, since the user can recognize the state where the cable is disconnected, it is possible to reliably transmit the data to the external device. This invention makes it possible to improve the reliability of the entire system.

Further, according to the embodiment of the present invention, regardless of the state of the external device when the portable terminal is connected, the portable terminal always performs the intended operation such as movement of the position designation display unit and menu selection. It becomes possible. This makes it possible to prevent the screen of the external device from entering a state unintended by the mobile terminal.

Further, according to the embodiment of the present invention, the user can switch the mode of the mobile terminal only by reading the optical information without having to operate the key of the mobile terminal. The present invention can improve the convenience of the user.

Further, according to the embodiment of the present invention, a large amount of optical information already on the market can be used in the system, and the range of application of the system can be expanded.

Further, according to the embodiment of the present invention, unnecessary data communication between the external device and the server due to a user's operation error can be prevented, and the convenience of the user can be improved.
