Next, the operation of the present embodiment according to the above configuration will be described with reference to a flowchart and the like showing the processing procedure of the reception processing unit 10. When the power is on and the FM multiplex mode is set, the reception processing unit 10 operates according to the flow shown in FIG. 4 and executes the selected program display process (step A1). That is, if the table of contents selection screen is selected, as shown in S1 of FIG. 5, the display unit 13 displays “1. Traffic information 2. News” based on the program contents data transmitted from the receiving broadcasting station. And the like, and the table of contents (“2. News” in the figure) selected in response to the operation of the cursor key is highlighted. Also, if an operation of selecting any program has already been performed from the table of contents of the program, for example, if an operation of selecting “2. News” has already been performed, as shown in S2 of FIG. Display the contents of the program.

The reception processing unit 10 monitors whether or not the pictogram setting key provided on the key input unit 12 has been operated while executing the selected program display processing (step A2). Is operated, a pictograph selection screen display process is executed (step A3). By the processing in step A3, a plurality of pictograms are displayed on the display unit 13 as shown in S3 of FIG. 5, and these pictograms are, for example, car pictograms that express traffic information in an image, weather forecasts are image-like. Is a pictogram of the sun. Next, a pictogram selection process is executed (step A4), and a desired pictogram is highlighted in response to an operation of a cursor key provided on the key input unit 12 by the process of step A4. Then, the process waits until the enter key is operated (step A5). If the enter key is operated, a process of adding the selected pictogram to the selected or displayed program is executed (step A6).

That is, the pictogram table 1 shown in FIG.
5A, the frequency area 1 corresponds to the pictograph code pre-written in the pictograph code area 15a.
5b, the reception frequency of the FM broadcast station received at that time is written, and the program number of the selected or displayed program is written in the program # area 15c. Therefore, FIG.
In the state where "2. News" is highlighted as shown in S1, or when the news program is displayed as shown in S2, the pictograph key is operated, and as shown in S3, the pictograph at the left end is displayed. (The code of this emoji is "01"
And ) Is operated with the cursor matched, and the frequency of the broadcast station A being received at this time is 80.
Assuming that the frequency is 0 MHz and the program number of the news at the broadcasting station A is “100”, as shown in FIG. 2, the pictogram code “01” in the pictogram code area 15 a
, "80.0" is stored in the frequency area 15b, and "100" is stored in the program # area 15c.

Further, as shown in FIG. 6 (1), with the table of contents of another broadcast station B being displayed, "1. News" is selected as highlighted and displayed in the same manner. ,
The pictogram of pictogram code "01" is selected and the enter key is operated, and the frequency of the broadcast station B being received at this time is 81.
Assuming that the program number of the news is 3 MHz and the program number of the news in the broadcasting station B is “105”, the pictogram code “01” in the pictogram code area 15a as shown in FIG.
, "81.3" is further stored in the frequency area 15b, and "105" is further stored in the program # area 15c. In addition, as shown in FIG.
In the state where the table of contents of the program is displayed, "3. News" is selected as highlighted, and similarly, the pictograph of pictograph code "01" is selected and the enter key is operated. The frequency of the receiving broadcasting station C is 82,5
MHz, and if the program number of the news in the broadcasting station C is "103", as shown in FIG.
In correspondence with pictogram code “01” in pictogram code area 15a, “82.5” is stored in frequency area 15b as a program #
"103" is stored in the area 15c. That is, by executing the process according to the flow shown in FIG. 4 a plurality of times, a plurality of frequencies and program numbers are stored in the pictogram table 15A in association with the same pictogram code. Of course, information of different information types, for example, "news" and "weather forecast" are converted to the same pictographic code "01" without associating only "news" of the same information type with the same pictographic code. It can also be stored in correspondence.

On the other hand, the reception processing unit 10 executes the processing according to the flow shown in FIG. 7 in parallel with the processing according to the flow shown in FIG. The contents of the program selected in advance by the broadcasting station are displayed (step B1). Further, the operation state of the memory key provided in the key input unit 12 is monitored while performing the program display processing (step B2). If the memory key is operated, pictograms are assigned to the program being displayed. In other words, it is determined whether a pair of data of the reception frequency of the currently receiving broadcast station and the program number of the program being displayed is stored in the pictogram table 15A in correspondence with any pictogram code. A determination is made (step B3). If the result of this determination is that there is a pictograph assignment, information + pictograph is recorded in the multiplex data memory 14A (step B).
5). By the process of step B5, as shown in FIG. 3, each memory area of the multiplex data memory 14A has
Multiple data, which is the content of the displayed program, is stored in association with the assigned pictogram code.

However, as a result of the determination in step B3, if no pictogram is assigned, it is determined whether or not a pictogram is assigned to an upper hierarchy of the same tree (same hierarchy) (step B4). That is, the programs of the FM multiplex broadcasting are configured in a hierarchy as shown in FIG. 8, the table of contents at the left end is the program number 000, and the table of contents of the information to be transmitted is “1. 4. The number of the program for displaying “traffic information”. Also, in the program of the program table of the program number 000, for example, the “traffic information” of the key-in number 4 is the middle table of the program table of the traffic information of the program number 130, and the table of contents of the traffic information of the middle layer. On the other hand, the program content of "Capital Expressway Information" of program number 131,
The program content of “general high-speed information” of program number 132 and the program content of “capital road information” of program number 133 are provided as lower layers.

Therefore, if the table of contents of the program number 000 is displayed and “4. Traffic information” is highlighted in the above-described flow at the time of assigning pictograms in FIG. The pictogram table 15A stores "130" as a program number together with the frequency. Further, in the flow at the time of pictogram assignment in FIG. 4, if the table of contents of the traffic information of program number 130 is displayed and “1. Metropolitan expressway information” is highlighted, and the pictograph setting key operation is performed, The pictogram table 15A stores “131” as the program number together with the frequency. Therefore, when the memory key is operated in the state where the program content of “Metropolitan Expressway Information” of the program number 131 is displayed during the execution of the flow shown in FIG. It is determined that there is an assignment, and the process proceeds from step B3 to step B5, where the pictographic code and the program contents of "Metropolitan expressway information" are stored in the multiplex data memory 14A.

However, when the flow shown in FIG. 7 is executed, the “general high-speed information” of the program number 132 and the program number 13
When the memory key is operated in a state where the program content of "General road information" of No. 3 is displayed, these program numbers and frequencies are not stored in the pictogram table 15A. It is determined that there is not, and the process proceeds from step B3 to step B4, and the above-described determination is performed in step B4. And this step B4
When the determination is made, referring again to the pictogram table 15A, the pictogram table in the above example has the same frequency as the frequency of the program of the program number 132 or 133,
Since the program number 130 of the upper hierarchy is stored, the determination in step B4 is YES, and the pictographic code of the upper hierarchy and the program contents of "general high-speed information" and "general road information" are multiplexed. It will be stored in the data memory 14A.

If the result of determination in step B4 is that there is no pictogram assigned to the upper layer, only the displayed information is recorded in the multiplexed data memory 14A (step B6). , "FF" indicating that there is no character code is stored.

On the other hand, the reception processing unit 10 also executes the processing according to the flow shown in FIG. 9 in parallel, and if an operation of a call key (read key) provided in the key input unit 12 is performed, The operation of the call key is fetched (step C1). Next, it is determined whether or not a pictograph search is designated by a predetermined operation on the key input unit 12 (step C2). If the pictograph search is not designated, the multiplex data is called from the multiplex data memory 14A in the recording order (step C2). Step C3) Display on the display unit 13. Therefore, when the pictogram search is not specified, the multiplex data recorded in the multiplex data memory 14A without the pictogram code being “FF” and the pictogram code is added is sequentially displayed together with the multiplex data to which the pictogram code is added. It is displayed on the unit 13.

However, as a result of the determination in step C2, if a pictogram search is designated, a pictogram selection screen is displayed on the display unit 13 (step C4). By the process of step C4, a plurality of pictographs each corresponding to a pictograph code are displayed on the display unit 13 as in S3 of FIG. 5 described above. Next, the process waits until an operation for designating the displayed pictogram is performed, that is, until an operation is performed in which one of the pictograms is highlighted and the execution key is pressed (step C5). When a pictograph is designated by performing such an operation, the pictograph code of the designated pictograph is compared with the pictograph code added to each multiplex data in the multiplex data memory 14A of FIG. C6) It is determined whether or not there is a pictograph code that matches the pictograph code of the designated pictograph in the multiplex data memory 14A (step C7). (Step C8) to recognize that the multiplex data corresponding to the pictogram designated by the user is not recorded in the multiplex data memory 14A. If there is a matching pictograph code in the multiplex data memory 14A, the multiplex data with the matching pictograph code is called in order (recording order) (step C9) and displayed on the display unit 13.

Therefore, by executing the processing according to the flow shown in FIG. 9, the multiplexed data received at the frequency corresponding to the pictogram by the processing according to the flow shown in FIG. The multiplex data of the program having the program number set is searched for each designated pictogram.
Here, in the processing according to the flow of FIG. 4, since an arbitrary frequency and an arbitrary program number correspond to the pictogram arbitrarily selected by the user, the flow shown in FIG. Through the processing, the user can search and display the multiplexed data stored in the unique classification for each classification, and can surely search and display only the desired type of information.

In this embodiment, as shown in FIG. 3, pictorial character codes and multiplexed data are stored in the respective areas of the multiplexed data memory 14A, but as shown in FIG. A memory area for each pictogram may be provided in the multiplex data memory 14A, and a memory area for no pictogram may be provided, and multiplex data to which the pictogram is assigned or multiplex data to which no pictogram is assigned may be stored in each area. According to such a configuration,
There is no need to add and store a pictographic code for each multiplexed data, and the amount of data to be stored can be reduced. Further, in this embodiment, the case where the present invention is applied to the FM multiplex broadcast receiving apparatus has been described. However, the present invention may be applied to a personal computer when performing pager or personal computer communication other than the FM multiplex broadcast receiving apparatus. Also, regarding the control unit program,
The information may be stored in a storage medium such as an IC card or a CD-ROM that is detachable from the apparatus main body.
