Meanwhile, CPU 25 of the information management apparatus 2 receives the bar code information by the communication circuit 26, and stores the bar code information to the RAM 23. CPU25 is, RA
By sequentially checking the barcode information stored in M23, it is possible to check the goods stored in the warehouse, the quantity thereof, and the like.

Based on the bar code information stored in the RAM 23, the CPU 25 determines the inventory management status of the warehouse as L.
Display on CD24. At this time, an inventory status screen 50 is displayed on the LCD 24, for example, as shown in FIG.
The stock status screen 50 displays the “date” of the same product that was delivered to the warehouse and the “quantity” currently stored in the warehouse.

[0048] Note that the user, for the products to be transferred out from the warehouse to the outside, preferably reads the bar code that is described in the packaging material of goods or products in the mobile telephone 7. At this time, the control circuit 46 of the mobile telephone 7, in the same manner as described above, step ST from step ST1
The processing of each step up to 5 is executed.

[0049] As a result, the information management device 2 CPU25

Is received by the information management device 2, the inventory management of the goods stored in the warehouse can be performed.

[0051] Particularly, since the user usually it can be used mobile telephone 7 which is mobile, it is not necessary to carry a dedicated terminal such as a POS terminal, thereby improving convenience compared to the conventional. Further, since data communication is performed between the information management device 2 and the mobile phone 7 by Bluetooth, there is also an effect that a call charge of the mobile phone 7 is not charged. Note that not only product inventory management but also product ordering and the like may be performed.

In this embodiment, the bar code (1
(Dimension code) has been described as an example,
Other can also be applied to a case of imaging a two-dimensional code such as Intacta code.

[0053] Further, in the embodiment described above, the level of the luminance signal of the bar code image was asking barcode information based on whether or not exceeding the threshold, the bar code information by using other techniques Of course.

ator), and a hard disk drive (HD) for storing various software such as application programs.
D) and 85, CPU 8 for transmitting and receiving and the overall control of data
And 6. In FIG. 7, but the WWW server 80 is described only one, the present invention is not limited thereto, it may be distributed by function be constituted by a plurality.

Here, the conversion table storage unit 84 stores a conversion table configured as shown in FIG. Conversion table, and a bar code, a URL corresponding to the bar code, in being configured. According to FIG.
For example, a bar code "123456789" is URL "h
http: // www. aaa. com / ", and the barcode" 987654321 "is the URL" http: //
/ Www. bbb. co. jp / ”.

[0061] The user can use the network system configured as described above, for example, by reading a barcode printed on the posters and leaflets can access a desired web site. here,
Supermarket sale flyer 90 shown in FIG.
Based on the barcode 91 described in
There will be described to access the super web site.

First, the user causes the mobile phone 7 to read the barcode 91 printed on the flyer 90. At this time, the control circuit 46 of the mobile phone 7 shown in FIG.
As shown in FIG. 1, from step ST11 to step ST1
The processing of each step up to 6 is executed.

[0063] In step ST11, the control circuit 46

Go to 14. As described above, when the mobile phone 7 acquires the barcode information, the mobile phone 7 sets the WWW server 8 set in advance.
0 is accessed.

In step ST14, control circuit 46
Reads barcode information stored in a memory (not shown). The wireless communication network 70 barcode information
And via the network 60, and transmitted to the WWW server 80, the process proceeds to step ST15.

On the other hand, the CP of the WWW server 80 shown in FIG.
U86 via the output port 81, the network 6
When detecting that the barcode information from 0 has been received,
The barcode information is stored in the RAM 82. And
The CPU 86 refers to the conversion table stored in the conversion table storage unit 84 and determines whether the same barcode information as the transmitted barcode information is described in the conversion table.

When the same bar code information as the transmitted bar code information is described in the conversion table, the CPU 86 determines the UR corresponding to the bar code information.
It reads L information, via the output port 81, the U
The RL information is transmitted to the mobile phone 7.

[0069] In step ST15, the mobile phone 7
The control circuit 46 determines whether it has received the URL information from the WWW server 80, waits until receiving the URL information, upon receiving the URL information, the process proceeds to step ST16. If there is no barcode information identical to the transmitted barcode information, the control circuit 46 notifies the mobile phone 7 that there is no URL information.

[0070] In step ST16, the control circuit 46
Uses the URL information transmitted from the WWW server 80 to access the website indicated by the barcode 91. The control circuit 46 receives the information on the website via the antenna 31, the LCD 45, for example, FIG. 1

By using the network system configured as described above, the user can read a URL described on a poster or a flyer, for example, and access a desired website. Here, FIG.
On the basis of the URL of the character described in the leaflets 110 of the sale exhausted selling super shown in 3, the mobile phone 7 will be described the case of direct access to the super web site.

[0078] First, the user, to read the letter (http://www.bbb.co.jp/) of printed on the leaflet 100 URL to the mobile phone 7. At this time, the control circuit 46 of the mobile phone 7 shown in FIG. 3 executes the processing of each step from step ST21 to step ST25 as shown in FIG.

In step ST21, the control circuit 46
Drives the CCD image sensor 40 to generate a flyer 9
The character image of the URL printed at 0 is read by the CCD image sensor 40. The control circuit 46 stores the character image of the URL read by the CCD image sensor 40 in the image memory 41, and proceeds to step ST22.

In steps ST22 and ST23, the control circuit 46 cuts out a character image for each character by using a predetermined algorithm. The extracts according to the algorithm a predetermined character features such as neighboring images and density feature from a character image extracted for each character in vector form, the process proceeds to step ST24.

[0081] In step ST24, the control circuit 46
Is matching the extracted feature vector and a recognition dictionary, the similarity is calculated for each candidate character. Candidate characters are
A category of characters registered in the recognition dictionary. Here, since the characters of the URL are to be recognized, uppercase and lowercase alphabets and some symbols are candidate characters. In general document reading devices,
Approximately 4000 characters including kanji and symbols are candidate characters. Then, the control circuit 46 determines that the candidate character having the highest similarity is a recognition character, and proceeds to step ST25.

[0082] In step ST25, the control circuit 46
Accesses the WWW server 80 using each URL's recognized character, and ends the process.

[0083] As described above, the network system according to a third embodiment of the present invention, the portable telephone 7 is printed flyers 100 URL directly recognized, the desired web site based on recognized characters direct access. Thus, the user, without having to enter the address information can be accessed easily directly to the desired website.

[0084] In the third embodiment from the first, the mobile phone 7 has the same configurations. Therefore,
The mobile phone 7 may have a mode switching function so that it can be used in each of the first to third embodiments.
