For the control unit 4, a ROM 15 storing a processing program, a key input unit 6 provided with a plurality of keys,
A display unit 7, a clock 8 for measuring the current time, a RAM 9 as a storage unit, and a reception control unit 10 for performing reception tuning of the FM tuner 32 according to an operation of a tuning key in the key input unit 6 are connected. ing. The key input unit 6 is provided with a power switch and various keys such as a menu key, a function key, an enter key, an up key and a down key shown in a flow described later,
The display unit 7 is composed of a main LCD and a sub LCD.

In the RAM 9, as shown in FIG.
Last memory 9a in M radio mode (mode in which only audio data is received and output, multiplexed data is not received and displayed) / FM multiplex mode (mode in which audio data is received and output, and multiplexed data is received and output), FM multiplex mode last Memory 9b, timers 1 to 3, and reception buffer 9
c is provided. The FM radio / FM multiple mode last memory 9a contains the FM radio mode or the FM radio mode.
In the multiplex mode, the frequency last set in the FM tuner 32 is stored, and in the FM multiplex mode last memory 9b, the received frequency last set in the FM tuner 32 in the FM multiplex mode is stored.

Each of the timers 1 to 3 has a timer setting time storage area 9d and an ON / OFF setting area 9e. The timer setting time storage area 9d stores the time when the power of the multiplex broadcast receiving apparatus 11 is turned on, which is input by the operation described later, and the ON / OFF setting area 9e indicates whether or not the corresponding timer is operated. Is stored and "1" is set when operating, and "0" is set when not operating. The reception buffer 9c stores multiplex data received by a timer, which will be described later,
Alternatively, the multiplex data received in real time is stored. At this time, the multiplex data received by the timer is added with an identification code and stored in order to distinguish it from the multiplex data received in real time, and the reception time data and the reception frequency data are also stored together. Note that the multiplexed data stored in the RAM 9 by timer reception or real-time reception is data that is erased when the user turns off the power supply, and the data in these RAM 9 is retained by the backup power supply even when the power supply is turned off. .

Next, the operation of the present embodiment having the above configuration will be described with reference to the flowcharts shown in FIGS. That is, in the state where the power is on and the FM multiplex mode is set, the control unit 4 operates according to the flow shown in FIG.
1) is performed to separate the multiplexed data (“London foreign exchange ...” exemplified in step A1) multiplexed in the received FM broadcast radio wave and store it in the reception buffer 9c. The data is read by selecting a desired table of contents and displayed on the main LCD of the display unit 7. Therefore, in this real-time reception state, the multiplexed data that is multiplexed and transmitted in the FM broadcast radio wave is sequentially transmitted to the main LC with only the time lag required for writing and reading to and from the buffer 9c.
D is displayed.

When the function key is operated in the key input section 6 in the state where the FM multiplex mode is set,
Multiple setting screen processing is performed (step A2). Then, the items "multiple timer setting" and "page feed setting" are displayed, and "multiple timer setting" is highlighted. When the enter key is operated with the "multiple timer setting" highlighted, and the clock 8 is not set (time adjustment) at this time, the process proceeds from step A2 to step A3. Then, in this step A3, the time adjustment request screen process is performed to display "the clock is not set" on the main LCD, and then the process returns to step A2. Further, when the clock 8 is set in advance and when the user sets the clock 8 according to the display in step A3 and then operates the enter key, the process proceeds from step A2 to step A4.

Then, in this step A4, each item of "timer 1""timer2""timer3""end" is displayed on the main LCD. In this state, the user operates the up or down key to
When either "Timer 2" or "Timer 3" is highlighted and the enter key is operated, any of the highlighted timers is selected, and the process corresponding to the selected timer is started. That is, "Timer 1"
When is highlighted and is pressed, the enter key is operated, and the flow advances from step A4-1 to step A5, and the timer 1 O
N / OFF setting processing is performed. ON / O of this timer 1
In the FF setting process, "ON""OFF" on the main LCD
Is displayed, and when the time is preset in the timer 1, the time is, for example, “AM12: 1
5 ”is displayed. Then, in this state, when "ON" is highlighted and ON setting for operating the enter key is performed, the process proceeds from step A5 to step A6. However, "OF
"F" is highlighted and the enter key is operated OFF
In the case of setting, the process proceeds to step A8 without performing the processes of step A6 and step A7. This step A
In step 8, "Set" is displayed and "0" is set in the ON / OFF setting storage area 9e.

When the ON setting is made and the process proceeds from step A5 to step A6, the hour data "A"
"M12" is displayed blinking. In this state, when the user operates the up key or the down key, the value of the time data changes with this operation. Then, when the enter key is operated while the desired time data is blinkingly displayed, the time data is determined and the process proceeds from step A6 to step A7. In step A7, the minute data "15" is displayed in a blinking manner, and when the user operates the up key or the down key in this state, the value of the minute data changes in accordance with this operation.

When the enter key is operated while the desired minute data is blinkingly displayed, the minute data is determined and the process proceeds from step A7 to step A8. In this step A8, "Set" is displayed, and in the timer setting time storage area 9d corresponding to the timer 1, step A6 is displayed.
Also, the hour data and minute data determined in step A7 are stored, "1" is set in the ON / OFF setting storage area 9e, and the process returns to step A4. In other words, the timer is a daily setting method that sets an arbitrary hour and minute during the 24 hours that configure one day, as exemplified in steps A5 to A7, and the preset hour and minute is set unless the set time is changed. Can be set continuously.

The same applies when another timer is selected in step A4.
"0" is set in the OFF setting storage area 9e. If it is ON, the corresponding timer setting time storage area 9d
Then, the hour data and minute data determined in step A6 and step A7 are stored, and "1" is set in the ON / OFF setting storage area 9e. Furthermore, in the state of step A4, when "END" is highlighted and the enter key is operated, the steps A4-3 to A
It returns to 1 and returns to the above-mentioned state of real-time reception. When the menu key is operated in the state of step A6 or step A7, the process returns to the previous step, respectively.

On the other hand, the control unit 4 performs the operations according to the flow shown in FIG. 4 in parallel. That is, the current time indicated by the clock 8 is constantly compared with the timer set time (ON set time) stored in the timer set time area 9d to determine whether or not the timer set time is reached ( In step B1), the standby state is maintained until the time set by the timer is reached. Then, when the timer reception time has come, it is determined whether or not the power is off (step B2), and if it is on, the process returns to step B1 without performing the subsequent processing. This is because if the timer reception process is performed during use with the power turned on, the mode and frequency will change arbitrarily. But,
If the timer reception time has come and the power is off at this time, the power is turned on and the frequency stored in the last memory 9b in the FM multiplex mode is set to the reception controller 10.
The FM tuner 32 is set via the, and reception of the broadcasting station corresponding to the frequency is started (step B3). At this time, the "multiple timer" that displays the frequency at which reception has started on the sub LCD and indicates that it is timer reception
Is displayed (step B3-1). Also, the main LCD
, A timer receiving screen is displayed to clearly indicate the reception frequency and the character "timer receiving" is displayed in a blinking manner (step B3-2). Therefore, the user can recognize that the timer is being received by visually observing this, and prevent the inconvenience that the user turns off the power or changes the reception frequency while receiving the timer. be able to.

Then, in the next step B4, the FM multiplex broadcast is received and accumulated, and by the processing of this step B4, the reception buffer 9c stores the identification code indicating the timer reception, the reception time data, and the reception frequency data. ,
It is stored with the received multiplex data. When multiple data is transmitted from the broadcast station together with a predetermined identification code indicating emergency information during this timer reception, the emergency information is displayed on the main LCD in real time (step B5). Therefore, as shown in the same step, when emergency information such as earthquake information is received,
Even if the power is off, the emergency information is displayed in the main LC.
Displayed in D, this multiplex broadcast receiver 11 effectively functions as an information transmission medium in an emergency.

After the emergency information is visually recognized, a normal checking operation is performed (step B6) and the menu key is operated to return to the screen during timer reception (step B7). Then, the timer reception is continued until a predetermined time (for example, 5 minutes, which is a time sufficient to receive the multiplex data once) has elapsed from the set time, and when the predetermined time has elapsed (step B8). ), The power is turned off (step B9). In this power-off state, the sub LCD continues to be in the ON state and displays the current time (step B9-1), and the main LCD is turned off to erase the display (step B9-2).

On the other hand, when the power is turned on, the control unit 4 operates according to the flow shown in FIG. 5, and the FM multiplex key provided in the key input unit 6 operates in the state where the FM radio mode is set. When operated, it is determined whether or not the multiple timer is set (step C1). When the multiple timer is not set, that is, RA
When all the ON / OFF setting areas 9e of M9 are "0", the table of contents reception screen processing (step C2) is performed,
The main LCD displays the message "Receiving table of contents ..." and the character "current" indicating that real-time reception is to be performed. Further, during this period, after the information currently transmitted from the broadcasting station is received and accumulated, a main table of contents display processing is performed (step C3), and the main table of contents shown in the step is displayed. In this state, when the user highlights one of the table of contents and operates the enter key, the normal operation is started and the multiplex data accumulated in the reception buffer 9c corresponding to the selected table of contents is displayed on the main LCD in real time. Is executed. If the FM multiplex key is operated during this real-time display,
Return to FM radio mode.

On the other hand, if the result of determination in step C1 is that multiple timers have been set, the reception buffer 9
It is determined whether or not there is timer reception data depending on whether or not the multiplex data to which the identification code is added is stored in c (step C4). If the result of this determination is that there is no timer reception data, that is, if timer reception has not been performed after the timer reception data stored in the reception buffer 9c has been cleared, as will be described later, a screen without timer data is displayed. A message to that effect is displayed (step C5). Subsequently, after each one second has passed, the reception start screen process (step C6) and the table of contents reception screen process (step C7) are sequentially performed to display each message, and the "current" character indicating that real-time reception is to be performed. Is displayed. Then, the real-time reception for receiving the current information is started, and when the FM multiplex key is operated after the real-time reception, the current information received is stored as it is and the mode returns to the FM radio mode.

As a result of the determination in step C4, if the timer reception data is stored in the reception buffer 9c, it is checked whether or not there is unconfirmed emergency information in the stored timer reception data. It is determined (step C8). If there is unconfirmed emergency information, display data information screen processing is performed (step C9) to display the reception time and the reception frequency of the emergency information stored in the reception buffer 9c, and the timer reception is performed. "Multiple timer" that indicates that is displayed blinking. Subsequently, after 1 second has elapsed, an emergency notification screen is displayed (step C10) to display that the emergency information has been received while the timer is being received, and an unillustrated sound source is instructed to generate an alarm sound signal. Amplifies signals 35a, 3
It supplies to speaker 36a, 36a via 5a, and produces an alarm sound. Further, the emergency information is displayed after 1 second has elapsed, and therefore, when the emergency information is received during the reception of the timer, the user can be notified of this without delay. When the user operates the menu key after confirming the displayed emergency information, the process proceeds from step C10 to step C12.

On the other hand, if there is no unconfirmed emergency information as a result of the determination in step C8, display data information screen processing is performed as in step C9 (step C1).
1) The reception time and the reception frequency of the information stored in the reception buffer 9c are displayed, and the characters "multiple timer" indicating the timer reception are displayed in blinking. Subsequently, after 1 second has elapsed, it is determined whether or not the table of contents can be displayed (step C12), and the table of contents cannot be displayed. If there is, after clearing the timer reception data stored in the reception buffer 9c,
A screen that cannot be displayed by the timer is displayed and a message to that effect is displayed (step C13).

That is, as will be described later in step C16, the multiplex broadcast receiving apparatus 11 calls the corresponding timer reception data from the reception buffer 9c by designating any one of the main contents, and the main LCD is displayed.
The configuration is displayed in. Therefore, the reception buffer 9c
If the main table of contents is not completely stored in and cannot be displayed, it becomes impossible to call up the information corresponding to each table of contents and display it on the main LCD. Therefore,
In such a case, the timer reception data stored in the reception buffer 9c is cleared, indicating that the information received by the timer cannot be displayed (step C1).
3). Thereafter, the reception start screen is displayed to indicate that the information on the air is received (step C14), and after 1 second has elapsed, the table of contents reception screen process (step C15) is performed, and the main LCD displays I'm receiving ... "
Display the message of Further, the character "current" indicating that real-time reception is to be performed is displayed, and reception of current information is started. When the FM multiplex key is operated after receiving this current information, the reception buffer 9 is used for real-time reception.
Return to FM radio mode, leaving the multiplex data stored in c as it is.

As a result of the determination in step C12, if the main table of contents is completely stored in the reception buffer 9c and the main table of contents can be displayed, the main table of contents is displayed and the multiplexed data received by the timer is displayed. The character of "multiple timer" indicating that there is is blinked (step C16). When one of the contents is selected while the main contents are displayed, the process moves to the display of past information, and the timer-received multiplexed data corresponding to the selected contents is called and displayed on the main LCD. Therefore, even immediately after the power supply of the multiplex broadcast receiving apparatus 11 is turned on, it is possible to quickly and visually recognize information without requiring time.

When the FM multiplex key is operated after visually observing the information received by the timer in this way, a transition confirmation screen is displayed (step C17), and "Receive latest information" and "Return to radio mode" are displayed. , "And" Receive the latest information "are highlighted. When the enter key is operated in this state, past information, that is, the multiplex data stored in the reception buffer 9c by timer reception is cleared, and then the process proceeds to step C15 described above. Therefore, when the enter key is operated while "Receive latest information" is highlighted, the multiplex data stored in the reception buffer 9c is erased by the timer reception. However, step C17
If the down key is operated without operating the enter key in this state, "return to radio mode" is highlighted instead of "receive latest information" (step C18). When the enter key is operated in this state, the past information stored in the reception buffer 9c after being received by the timer is left as it is, and the mode returns to the FM radio mode. Therefore, by performing such an operation, the past information received by the timer and stored in the reception buffer 9c can be viewed again later.

Although omitted in the flow chart shown in FIG. 5, after the contents reception screen processing is performed in step C7 and step C15 to receive the current information, the above-mentioned step C3 is performed.
Subsequent main table of contents display processing and normal operation are performed.

When it is determined in step C1 that the multiple timer is not set, and in step C4
When it is determined that there is no timer reception data in,
When the multiplex data received at the same receive frequency as the receive frequency currently set in the FM tuner 32 is stored in the receive buffer 9c, the stored multiplex data is used without performing the multiplex data receiving process. Then, the main table of contents display processing is immediately performed.

Further, in this embodiment, the multiplex data received by the timer can be distinguished from the multiplex data received in real time by adding the identification code and storing it in the reception buffer 9c. However, without adding an identification code, both multiplexed data can be identified by storing flag information indicating whether or not each of the timers 1 to 3 has operated. In this case, the flag information may be reset when the latest information is received or the power is turned off.

[0034]

As described above, according to the present invention, a multiplexed information receiving apparatus for receiving and storing information multiplexed and transmitted in FM broadcast waves and displaying the stored information is transmitted. A reception start time of information is set, and when the current time reaches the reception start time, the information is received and stored, and the stored information is displayed according to a predetermined calling operation. Therefore, it becomes possible to view the information even immediately after the power is turned on, and it is possible to quickly view the information even under the condition that the reception state is poor and it takes time to store the information.

Further, when the current time reaches the reception start time, the control is executed when the power supply of the multiplex broadcast receiving device is off, so that the mode and the reception frequency are arbitrary while the power is on.
