If it is a control signal, it is given to the control means, and if it is a sound signal, it is given to the sound processing means 14. The audio signal processing means 14 decodes the audio signal to convert it into an analog signal, and supplies the analog signal to the speaker 4. Further, the analog signal from the microphone 15 is encoded and converted into an audio signal, and the audio signal is supplied to the signal processing unit 13.

The operation of the block diagram shown in FIG. 1 will be described. An FM broadcast signal received via an antenna 1 is subjected to FM detection by a receiving means 2, and an audio signal is output as audio via an amplifier circuit 3 and a speaker 4. Is done. on the other hand,

FIG. 2 is an external view of the information terminal device of the present invention.

On the front face of the apparatus, there are provided a speaker 4 for outputting received information as voice and a display means 11 for displaying the information as characters. Further, on the front and side surfaces of the apparatus, operating means 9 having a plurality of operation keys for realizing each function and buttons for adjusting the volume and the receiving frequency are provided. An antenna 1 is provided on the upper surface.

First, a method of receiving FM multiplex broadcasting will be described.
This will be described with reference to the flowcharts of FIGS. The flowchart of FIG. 3 shows the flow of the entire information terminal device of the present invention. In S301, the mode of the device is determined. If the mode is the radio mode, the process proceeds to the radio subroutine of S302. It is designed to go to a telephone subroutine. Therefore, if the user sets the radio mode with the mode key in the operation unit 9, the mode is determined to be the radio mode in S301, and the mode is determined in S302.
Proceed to the radio subroutine.

FIG. 4 is a flowchart showing the flow of the above radio subroutine. When entering this routine, first, in step S401, the power of the radio circuit such as the receiving unit 2 and the PLL circuit 8 is turned on. And S402
Then, the output is inverted according to the operation of the AM / FM key in the operating means 9. For example, based on the output of the band instruction signal circuit constituted by the T flip-flop, whether the currently received radio broadcast is the FM broadcast or not. Is determined,
If “YES”, the process proceeds to S403. In S403, whether or not the currently received broadcast is an FM multiplex broadcast is determined based on the output of the multiplex signal extraction filter 6, and "Y
If "ES", the process proceeds to S404. S404, S405
In, demodulation and display of the multiplex signal are performed, and the process proceeds to S406. S406 is a multiplexed information extraction subroutine described later. When this subroutine ends, the process proceeds to S407.

If "NO" in S402, S4
Steps 03 to S406 are omitted, and “N
If “O”, steps S404 to S406 are omitted, and the process proceeds to S407.

At S407, it is determined whether or not a band switching operation or a frequency switching operation has been performed. If "YES", the process proceeds to S4.
At 08, a band switching operation or a frequency switching operation is performed to tune to a previously received broadcast station or a broadcast station of the designated frequency in the selected band. Also S4
If “NO” in 07, the radio subroutine ends.

Therefore, when the user operates the AM / FM
If the frequency is adjusted to a predetermined FM broadcast station by operating the keys and the adjustment buttons, the FM broadcast is received in S401 to S405, and if a multiplex signal is included, the multiplex signal is demodulated, as shown in FIG. Then, the multiplex information is displayed on the display means 11.

Next, a method of extracting the displayed multiplex information will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart showing the flow of the multiplex information extraction subroutine. In S501, the presence or absence of the operation of the cursor key is determined. If “YES”, the process proceeds to S502, and if “NO”, the multiplexed information extraction subroutine ends. In S502, a cursor is displayed at the position coordinates (1, 1), that is, the upper left of the display screen, and the process proceeds to S503. In S503, the presence or absence of a key operation is determined. If it is a cursor key operation, the cursor is moved in S504 and the process returns to S503. If the operation is a memory key operation, the position coordinates of the cursor are stored in S505, and the process proceeds to S506. S
At 506, it is determined whether or not the number of times the memory key has been operated is the first time.
If it is the first time, in S507, the multiplex information from the first storage position coordinate to the current position coordinate is stored in the storage means, and the multiplex information extraction subroutine is terminated. Where S
If the clear key is operated in 503, the process ends immediately.

Therefore, when the user presses the cursor key of the operation means 9 once while desired multiplexed information is displayed on the display means 11, an inverted cursor is displayed at the upper left of the screen, and thereafter, the left and right cursors are displayed. By operating the cursor keys, the cursor can be moved to a predetermined position.

If the displayed information is, for example, a request telephone number, the cursor key is operated to move the cursor to the first numeral of the displayed telephone number and press the memory key once. . Thereby, the start position of the multiplexed information to be stored is determined. After that, by pressing the cursor key again, the reversal state is extended to the range necessary for storing, and after operating the cursor key so that the last number of the telephone number is reversed, by pressing the memory key again, The selected telephone number is stored in the storage unit 12 as telephone number information.

Next, a dial transmission method will be described with reference to the flowchart of FIG. In S601, it is determined whether or not the call key has been operated, and if "YES", the process proceeds to S6.
Proceed to 02, and if "NO", terminate the telephone subroutine. In step S602, the latest telephone number information stored in the storage unit is displayed on the display unit, and the process proceeds to step S603.
In step S603, it is determined whether a key or button operation has been performed.
When the adjustment button is operated, the telephone number information stored immediately before is displayed on the display means in S604, and the process returns to S603. If the call key has been operated, the process proceeds to S605, in which the telephone number information corresponding to the displayed telephone number is output to the signal processing means 13, a calling process is performed in S606, and the telephone subroutine ends.

When the clear key is operated in S603, the telephone subroutine is immediately terminated.

Therefore, when the mode key of the operation means 9 is operated to switch to the telephone mode and then the call key of the operation means 9 is operated, the control means 10 reads out the latest stored telephone number information from the storage means 12. Then, the display means 11 displays the telephone number. Further, by pressing the adjustment button on the side, the telephone numbers stored so far are sequentially displayed.

Then, by operating the adjustment button so that the telephone number to be transmitted is displayed, and operating the call key when the desired telephone number is displayed, the control means 10 is displayed on the display unit 11. The telephone number information corresponding to the telephone number being read is read out from the storage means 12 and the signal processing means 13 is read out.
, And thereafter performs transmission processing via the transmitting means 17 and the antenna 1.

Therefore, when the telephone number is displayed on the display section, the user can select and store the telephone number with the cursor key and the memory key, and can dial the number at any time. Become.

[0027]

As described above, according to the present invention, multiplexed information such as a received telephone number can be stored and signal processing such as dialing can be performed based on the multiplexed information, which is very simple.
