A signal for constantly displaying 5 is sent to the display control unit 34.

The display control section 34 controls turning on / off of the display section 5. When a signal for constantly displaying the display section 5 is input from the functional operation on / off section 31, the display control section 34 constantly turns on the display section 5.

In the present embodiment, values shown in Table 1 below are used as specific values of the voltage value and the timer value.

[0032]

[Table 1] The battery voltage of the radio selective calling receiver of this embodiment is 1.5 V
It is.

The timer value coincidence judging section 35 compares the count value of the counter 9 with the timer value set by the timer activating section 32, and when the timer value coincides with the count value, the display control section 34 displays it. 5 is output.

Next, the operation of the present embodiment will be described in detail with reference to FIG. 1, FIG. 2, and FIG.

First, the setting operation of the standby function performed by the function operation on / off unit 31 will be described with reference to the flowchart of FIG.

First, the function operation on / off section 31 displays an input request for selecting whether to turn on or off the standby function (step 102). Then, the functional operation on / off unit 31 waits until an instruction to turn on or off the standby function is input from the input unit 4 (Step 103). When an instruction is input from input unit 4, functional operation on / off unit 31 determines whether the instruction is an instruction for turning on or off the standby function (step 10).
4). If the instruction from the input unit 4 is an instruction to turn off the standby function, the function operation on / off unit 31
Sets the display control unit 34 to always turn on the display (step 107). If the instruction from the input unit 4 is an instruction to turn on the standby function, the function operation on / off unit 31 sends an ON signal to the timer starting unit 32 to start the timer starting unit 32 (step 105). ). Then, the function operation on / off unit 31 ends the process when the timer activation unit 32 is activated (Step 106).

Next, the timer starting function performed by the timer starting unit 32 will be described with reference to the flowchart of FIG.

First, upon receiving an ON signal from the function operation ON / OFF unit 31, the timer activation unit 32 waits for an input from the input unit 4 to activate the battery voltage detection unit 36 and the timer value setting unit 33. Is performed (step 201). Then, when there is an input from the input unit 4, the timer starting unit 32 starts the battery voltage detecting unit 36 and the timer value setting unit 33 (Steps 202 and 203). Next, the battery voltage detector 36 detects the battery voltage, and notifies the timer setting unit 33 of the detected voltage value (Step 204).

The timer value setting section 33 includes a battery voltage detecting section 3
It is determined whether the detected voltage value is higher or lower than the predetermined voltage value (step 205). If the voltage value is higher than the predetermined voltage value (1.4 V or more), the longer timer value (5)
Minute) is set (step 206). Timer value setting unit 3
3 sets a short timer value (1 minute) if the voltage value detected by the battery voltage detection unit 36 is lower than a predetermined voltage value (1.3 V or less) (step 214). Then, the timer value setting unit 33 stores the set timer value in the storage unit 7 and ends the processing (Step 207).

Next, when the timer value is set in the storage unit 7, the timer starting unit 32 performs a count start process (step 208). The count start process is a process for setting the timer value stored in the storage unit 7 to the timer match determination unit 35 and the counter 9. After performing the count start process, the timer starting unit 32 monitors the input of the input unit 4 (Step 209), and when there is an input, performs the stop process of the counter and returns to the process of Step 202 (Step 21).
5). If there is no input from the input unit 4, the timer value match determination unit 35 is monitored to determine whether the count value of the counter 9 matches the timer value (step 210).

When the timer value coincides with the count value of the counter 9, the timer value coincidence judging section 35 sends a signal to turn off the display to the display control section 34 (211). The display control unit 34 turns off the display unit 5 in response to the display turn-off signal (step 212), and ends the process (step 213).

When the signal transmitted from the base station is received and the message is displayed while the display unit 5 is turned on, the timer starting unit 32 sets the counter value of the counter 9 again. From that point, the counting up of the counter value is started. When a message is received from the base station while the display unit 5 is turned off, the display control unit 34 turns on the display of the display unit 5.

In the present embodiment, two timer values are switched and set based on the voltage value detected by the battery voltage detector 36. However, the present invention is not limited to this, and the detected voltage value The present invention can be applied to a case where three or more timer values are set and used based on the above. For example, as an example, the present invention can be applied similarly to the present embodiment when using the voltage values and the timer values shown in Table 2 below. In Table 2, the voltage value is in the unit of 0.1 V because the voltage value obtained by the battery voltage detecting unit 36 is in the unit of 0.1 V.

[0044]

[Table 2] The numbers of the voltage value and the timer value in the present embodiment are merely examples for specifically describing the present invention, and the present invention is not limited to this, and voltage values of other values,
The same applies to the case where a timer value is used.

[0045]

As described above, according to the present invention, the display section is turned off after a certain period of time has elapsed since the operation of the switch or the like, and the time is changed according to the value of the battery voltage. This has the effect of reducing current consumption and extending the life of the battery.
