Etc. are provided.

B. Operation Next, operations of the main routine and timer interrupt processing executed by the control unit 102 will be described with reference to FIGS. 2 to 6 as operations related to the gist of the present invention.
(1) Operation of main routine When the power switch of the mobile phone 10 is operated and the power is turned on, the control unit 102 executes the main routine shown in FIGS. When the main routine is executed, the process proceeds to step SA1 shown in FIG. 2, and initialization for initializing each part of the mobile phone 10 is executed. In step SA2, the standby image data read from the ROM 103 is stored in the display area of the RAM 104, and a standby screen is displayed on the display unit 108 based on the stored standby image data. Next, in step SA3 and subsequent steps, processes corresponding to the on operations of the off-hook switch, the on-hook switch, the channel registration switch, and the broadcast reception switch arranged in the operation unit 105 are executed. The processing operation corresponding to each switch operation will be described below.

a. When the off-hook switch is turned on It is assumed that the user operates the off-hook switch to start a call. Then, the determination result in step SA3 is “YES”, and the process proceeds to step SA4. In steps SA4 to SA5, the screen displayed on the display unit 108 is changed from the standby screen to a number input screen, and the telephone number input according to the dial switch operation is set on the number input screen while being displayed. Subsequently, in steps SA6 to SA7, calling and calling notification are executed based on the telephone number set in the register. When the called party goes off-hook in response to the call notification and the line is connected, the determination result in step SA8 is “YES”, and the process proceeds to step SA9 to execute a call process. Thereafter, the call processing in step SA9 is continued until the on-hook switch is turned on.

b. When the on-hook switch is turned on It is assumed that the user turns on the on-hook switch during the call processing at step SA9. If it does so, the judgment result of Step SA10 will become "YES", and it will progress to Step SA11, and after performing the end-of-line process which cuts a line, will return to above-mentioned step SA2, and will return to a standby screen display state.

c. When the channel registration switch is turned on When the user turns on the channel registration switch, the determination result in step SA12 shown in FIG. 3 is “YES”, and the process proceeds to step SA13. In step SA13, a channel registration screen is displayed on the display unit 108 based on the channel registration screen data read from the ROM 103. The channel registration screen is a screen provided with input areas IE1 to IE4 for registering and setting channels with priority levels 1 to 4 that are received with priority, as in the example illustrated in FIG. When such a channel registration screen is displayed on the display unit 108, the control unit 102 advances the processing to step SA14, and displays an input cursor in the input area IE1 with priority level 1.

Next, in steps SA15 to SA20, processing corresponding to channel registration operations (cursor switch operation, data input operation, determination switch operation, and clear switch operation) performed in a state where the channel registration screen is displayed is executed.
That is, when the clear switch is turned on to cancel the channel registration operation, the determination result in step SA20 is “YES”, and the process returns to the above-described step SA2 (see FIG. 3) to enter the standby screen display state. Return.

  On the other hand, when the cursor switch is turned on to move the input order, the determination result in step SA15 is “YES”, and the process proceeds to step SA16 to move the position of the input cursor. When data is input (channel registration) in a state where the input cursor is positioned in the input area of the desired order, the determination result in step SA17 becomes “YES”, and the process proceeds to step SA18 to input data at the input cursor position. indicate. When the determination switch is turned on after the data is input, the determination result in step SA19 is “YES”, and the flow proceeds to step SA21. In step SA21, it is determined whether data has been input to all of the input areas IE1 to IE4 on the channel registration screen.

If there is an input area that has not been input, the determination result is “NO”, the process proceeds to step SA22, the input cursor is moved to the input area that has not been input, and the process returns to step SA15. On the other hand, as shown in FIG. 6B, for example, if data is input to all of the input areas IE1 to IE4 on the channel registration screen, the determination result in step SA21 is “YES”, and step SA23 is performed. Then, after the priority order is registered, the process returns to the above-described step SA2 (see FIG. 3) to return to the standby screen display state.
In the present embodiment, the station name and the broadcast name are input in the input areas IE1 to IE4 on the channel registration screen. Instead, for example, the channel number selected from the list of receivable channels is input area. It does not matter as a mode of registering in IE1 to IE4.

d. When the broadcast reception switch is turned on When the user turns on the broadcast reception switch, the determination result in step SA24 shown in FIG. 4 is “YES”, the process proceeds to step SA25, and an initial value (channel number) is stored in the channel register CH. Store. Next, in step SA26, it is determined whether or not the broadcast is received on the channel of the channel number stored in the channel register CH. If the broadcast is received, the determination result is “YES”, and the process proceeds to step SA27, and the reception contents of the channel number stored in the channel register CH among the reception outputs output by the reception unit 201 are displayed on the display unit 108 and the speaker. It outputs to 107.
On the other hand, if the broadcast of the channel number stored in the channel register CH is not received, the determination result in step SA26 is “NO”, and the process proceeds to step SA28 to display a warning that reception has been stopped. Displayed on the unit 108.

  Subsequently, in steps SA29 to SA30, it is determined whether or not there is a channel switching operation and a broadcast receiving switch off operation. When the channel switching operation is performed, the determination result in step SA29 is “YES”, and the process proceeds to step SA31, where the channel number changed according to the channel switching operation is stored in the channel register CH, and then the above-mentioned. The process returns to step SA26. When the broadcast receiving switch is turned off, the determination result in step SA30 is “YES”, and the process returns to step SA2 (see FIG. 3) to return to the standby screen display state.

(2) Operation of Timer Interrupt Process Next, the operation of the timer interrupt process will be described with reference to FIG. The control unit 102 interrupts and executes this process at predetermined intervals during execution of the main routine described above. When this process is interrupted, the control unit 102 proceeds to step SB1 shown in FIG. 5 and detects the remaining battery level of the battery 110 (remaining battery charge level) from the detection signal output from the battery capacity detection circuit 109. To do. Next, in step SB2, a receivable level is determined based on the detected remaining battery level. That is, the number of channels that can be simultaneously received by the receiving unit 201 is estimated from the remaining battery level, and it is determined which of the above-mentioned priority levels (receivable levels) registered in the channels corresponds to the number of channels.

  For example, if the number of channels that can be simultaneously received by the receiving unit 201 with the detected remaining battery level is “1”, in the example of the priority order illustrated in FIG. Only “△ TV” can be received. As a method for determining the receivable level based on the detected remaining battery level, for example, a table in which the remaining battery level is associated with the number of simultaneously receivable channels of the receiving unit 201 is provided. There is a method of reading the number of simultaneously receivable channels from the table.

  In this way, when the receivable level is determined from the detected remaining battery level, the control unit 102 proceeds to step SB3 and stores an initial value (channel number) in the channel register CH. Subsequently, in step SB4, the reception content of the channel having the channel number stored in the channel register CH is specified. In step SB5, it is specified which of the above-mentioned priority levels (receivable levels) registered in the channel corresponds to the specified received content. Next, in step SB6, it is determined whether or not the specified received content is in priority (receivable level). If the specified received content is not in the priority order (receivable level), the determination result is “YES”, the process proceeds to step SB7, and the reception operation is stopped (power off) for the channel of the channel number stored in the channel register CH. After instructing the receiving unit 201, the process proceeds to step SB8. When the reception unit 201 is instructed to stop the reception operation in step SB7, a reception stop warning is displayed in step SA28 (see FIG. 4) of the main routine described above.

  On the other hand, if the specified received content is in priority (receivable level), the determination result in step SB6 is “NO”, and the flow advances to step SB8. In step SB8, the channel number stored in the channel register CH is incremented and incremented, and in the subsequent step SB9, whether or not the incremented channel number exceeds the number of reception channels, that is, whether or not the channel scan is completed. Judging. If the channel scan is not completed, the determination result is “NO”, and the process returns to step SB4 described above. Thereafter, the received content of the stepped channel number is specified, and the channel scan for determining whether the specified received content is in the priority order (receivable level) is continued. When the channel scan is completed, the determination result in step SB9 is “YES”, the process is completed, and the process returns to the main routine described above.

  As described above, in this embodiment, priorities of channels that are preferentially received according to the remaining battery level are set in advance, and channels that can be received simultaneously with the detected remaining battery level among the priorities. Since only the channels within the order of several minutes are received, it is possible to continue receiving a part of the broadcast while saving power without stopping the reception uniformly when the remaining battery level is low during simultaneous reception of multiple channels. Thus, for example, when the reception of the TV broadcast and the recording and the reception of the FM broadcast and the electronic program EPG are received, the remaining battery level is reduced during multi-channel simultaneous reception, and only one channel can be received. In the example shown in the figure, only TV broadcast reception recording can be continued.

  In the above-described embodiment, the receiving operation is performed only for the channels within the order of the number of channels that can be received simultaneously with the detected remaining battery level. When simultaneously recording (recording), it is also possible to perform a reception recording operation only on channels within the rank of the number of channels that can be recorded simultaneously with the detected remaining battery level.
