FIG. 20 shows a flowchart of the deletion permission / inhibition determination process executed in step S71.

The control unit 4 refers to the ID 30 of the information group corresponding to the information code of the record being referenced, and determines whether there is a next reproduction information code, that is, the information group corresponding to the information code of the record being referenced. It is determined whether or not there is an information group serving as a reference transition destination (step S91). If there is a next reproduction information code (step S91; Yes), all the information groups corresponding to the next reproduction information code have expired. In other words, it is determined whether or not all information groups that are transition destinations based on the information group corresponding to the information code of the record being referred to have expired (step S92).

Whether or not the expiration date has expired in step S92 is determined if the current date and time is after the end date of the ID04 of each information group corresponding to the next reproduction information code. Is determined.

When there is no next reproduction information code (step S91; No), or when all the information groups corresponding to the next reproduction information code have expired (step S92; Yes), the control unit 4 determines that deletion is possible. It discriminate | determines (step S93) and complete | finishes this process.

If all the information groups corresponding to the next reproduction information code have not expired (step S92; No), the control unit 4 determines that the deletion is not possible (step S94), and ends this process.

FIG. 21 shows another flowchart of the deletion permission / inhibition determination process executed in step S71. Steps S101 and S102 are the same as steps S91 and S92 in the deletion permission / inhibition determination process shown in FIG.

When all the information groups corresponding to the next reproduction information code have not expired (step S102; No), the control unit 4 does not go through the information group corresponding to the information code of the record being referred to, It is determined whether or not there is a transition route that can reach the information group corresponding to the next reproduction information code from the upper information group (step S103).

When there is no next reproduction information code (step S101; No), the control unit 4 is when all information groups corresponding to the next reproduction information code have expired (step S102; Yes), or referring to If there is a transition route that can reach the information group corresponding to the next reproduction information code from the highest information group without going through the information group corresponding to the information code of the record being recorded (step S103; Yes), it is determined that deletion is possible. (Step S104), and this process is terminated.

When there is no transition route that can reach the information group corresponding to the next reproduction information code from the highest information group without passing through the information group corresponding to the information code of the record being referred to (step S103). No), it is determined that deletion is not possible (step S105), and this process is terminated.

An example of the discrimination method in step S103 will be described.
First, it is assumed that the information group stored in the storage unit 1f forms a hierarchical structure (tree structure) as shown in FIG.

For example, if the information group “5” in FIG. 22 is an information group corresponding to the information code of the record referred to, the information from the highest level information group “1” without passing through the information group “5”. A case will be described in which it is checked whether there is a transition route that can reach information groups “8” and “9” corresponding to the next reproduction information code of group “5”.

A case where the presence / absence of a transition route is determined for the information group “8” will be described.
First, it is necessary to search for a transition source of the information group “8”. However, since the information group does not have information indicating the transition source, the control unit 4 sets an information code as a transition destination for all the information groups. It is searched whether or not “8” is designated, that is, whether or not there is an information code “8” in the next reproduction information code of ID30. In the case of the hierarchical structure shown in FIG. 22, the information code “8” is designated as the transition destination of the information group “4” (the information code “8” is included in the next reproduction information code). It is determined that there is also an information group that can transition to the information group “8”, that is, a transition source other than the information group “5”.

Next, the control unit 4 searches the transition source of the information group “4” by the same process as the process of searching the transition source of the information group “8”, and determines that the information group “2” is the transition source. To do. Further, the control unit 4 similarly searches for the transition source of the information group “2” and determines that the information group “1” is the transition source.

Therefore, it is found that the information group “8” can transition from the information group “1” to the information group “2” and the information group “4”.

When the information group “9” is searched in the same manner, the information group “9” is determined to be able to transition from the information group “1” to the information group “3” and the information group “6”.

From the above, it is determined that there is a transition route that can reach the information groups “8” and “9” corresponding to the next reproduction information code from the highest information group “1” without passing through the information group “5”. The information group “5” can be deleted.

If the connection with the external network N2 has been established (step S134; Yes), the information shown in FIG. 27 or FIG. Update processing is executed (step S135), and this processing ends.

When the connection to the external network N2 is not established (step S136; No), the control unit 4 notifies the message indicating that the connection to the external network N2 cannot be established by displaying the text on the screen of the display unit 1e or speaking. (Step S136), the process is terminated.

FIG. 27 shows a flowchart of the information update process executed in step S135. In the information update process shown in FIG. 27, it is assumed that there is a link file for accessing information update data in the page of the URL displayed by the web browser based on the URL included in the information group.

The control unit 4 reads the URL from the ID 10 of the information group (step S141), starts the web browser (step S142), and sets the read URL in the web browser (step S143).

The web browser acquires the file specified by the URL set via the external network N2 by the wireless communication unit 5 (step S144), analyzes the content of the acquired file, and displays a screen showing the content of the file It is displayed on the part 1e (step S145).

The screen displayed in step S145 includes various icons such as an icon in which a link file to information update data is set. When an icon selection instruction is received by the input unit 1d, the web browser acquires a link file corresponding to the selected icon via the external network N2 (step S146), and the acquired link file is information update data. Whether the file is a link file (information update file) is determined (step S147).

It is assumed that an extension (for example, “.tcln”) attached to the information update file and an application that executes the information update file are stored in the web browser in advance. The web browser determines whether the extension of the acquired link file matches the registered extension, thereby determining whether the file is an information update file.

If the acquired link file is not an information update file (step S147; No), the web browser returns to step S144, and if it is an information update file (step S147; Yes), executes the information update file. The application (information update application) is activated and the information update file is transferred to the information update application (step S148).

After step S148, the control unit 4 terminates the web browser (step S149), executes the information update application, and analyzes the acquired information update file (step S150).

The control unit 4 determines whether or not there is an error in the data format or the like of the information update file (step S151). If there is an error (step S151; No), “the data cannot be updated because of an error” The error message such as the above is notified by displaying the text on the screen of the display unit 1e or speaking (step S152), and the process is terminated.

When there is no error in the data format or the like of the information update file (step S151; Yes), the control unit 4 determines whether the information update file has not expired (step S153). Whether or not the expiration date is not expired in step S153 can be determined that the expiration date (last year / month / date / time) of the information update file is not later than the current date / time.

When the information update file has expired (step S153; No), the control unit 4 displays a message indicating that there is no updated information group, such as “There was no updated information”, on the display unit 1e. This is notified by displaying text on the screen or speaking (step S154), and the process is terminated.

When the information update file has not expired (step S153; Yes), the control unit 4 rewrites and updates the information group stored in the storage unit 1f requested to be reproduced with the data of the information update file (step S153). S155), a message indicating that the information group such as “information has been updated” has been updated is notified by text display on the screen of the display unit 1e or by speaking (step S156), and this processing Exit.

FIG. 28 shows another flowchart of the information update process executed in step S135. In the information update process shown in FIG. 28, the information update URL included in the information group or a part of the URL included in the information group is changed according to a predetermined rule (for example, the extension is replaced with “.dsrc”). Information update data is acquired via the external network N2 without using a web browser.

The control unit 4 acquires a URL for updating information from the information group (step S161).
In step S161, the URL for updating information may be acquired as an information update URL, or may be acquired as an information update URL by changing a part of the URL.

First, a case where an information update URL is acquired will be described.
When a plurality of URLs can be stored in the ID 10 of the information group, the information update URL is acquired by referring to the ID 10 and referring to the extension of the file specified by each URL among the plurality of URLs. For example, when the extension is “.tcln”, the URL is set as the information update URL, and the URL that matches the extension is searched from the ID 10 to obtain the information update URL. When storing the information update URL in the detailed information of the ID 40 of the information group, the information update URL is acquired with reference to the ID 40.

A case where a part of the URL is changed and acquired as an information update URL will be described.
A URL is acquired from the ID 10 of the information group, a part of the acquired URL is changed according to a predetermined rule, and the changed URL is acquired as an information update URL.

An extension can be given as a part of the URL. For example, the extension “.html” of the acquired URL is changed to “.dsrc”.
Acquisition URL http: // www. kxxx. co. jp / index. html
Change URL http: // www. kxxx. co. jp / index. dsrc
The extension is not limited to “.dsrc”, but is not limited to this as long as other data can be easily distinguished.

A file name can be given as a part of the URL. For example, the file name “index.html” of the acquired URL is changed to “update.tcln”.
Acquisition URL http: // www. kxxx. co. jp / index. html
Change URL http: // www. kxxx. co. jp / update. tcln

When acquiring the URL for updating information (after step S161), the control unit 4 acquires the file (information update file) specified by the acquired URL via the external network N2 by the wireless communication unit 5 (step S162). ).

The control unit 4 determines whether or not the information update file has been acquired (step S163), and when the information update file cannot be acquired (step S163; No), “Update data could not be acquired” or the like. A message indicating that the information group for update cannot be acquired is displayed on the screen of the display unit 1e as text or spoken (step S164), and this process is terminated.

When the control unit 4 can acquire the information update file (step S163; Yes), the control unit 4 proceeds to step S165. Steps S165 to S171 are the same as steps S150 to S156 shown in FIG.

As described above, according to the present embodiment, it is possible to improve convenience when displaying the distribution information to which the expiration date information is added.
