〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of essential parts of an embodiment of an individual selective calling receiver of the present invention. The individual selective calling receiver of this embodiment is different from the conventional individual selective calling receiver shown in FIG. , the power supply switch 10 in FIG.
7 is connected to this power on/off controller 9, and a switch group 10 including switches SW1 to SWn for setting power on/off times, etc. is connected to the power on/off controller 9. It is located at the point connected to 9.

Various means for implementing the power on/off controller 9 can be considered, and the present invention is not limited to the implementation means. Below, as shown in FIG.
2, RAM93, Cronk generator 94. Regarding an embodiment in which the power on/off controller 9 is realized by a low power consumption microcomputer in which the human interface 95 and the output interface 96 are integrated into one chip, for example, see FIGS. 3 to 6 showing operation flowcharts. and explain.

The ROM 92 in the power on/off controller 96 in FIG. 2 contains a program for causing the MPU 91 to execute the operations shown in FIGS. It is stored in advance. In this embodiment, the power-on allowable time WT is stored in the ROM, but it is of course possible to store it in a rewritable non-volatile memory.

When the battery 6 is incorporated into the individual selective call receiver shown in FIG.
Power is supplied to the power on/off controller 9.

When power is supplied to the power on/off controller 9, the operation shown in FIG. 3 starts.

First, the MPU 9 1 of the power on/off controller 9 is a RAM
Reset the current time count area (area that holds the current time consisting of hours, minutes, and seconds) set in a part of the area of 93 to OO hours 00 minutes 00 seconds, and start counting the current time from its initial state. Start (S1). That is,
Based on the clock generated by the clock generator 94, the value of the current time counter HI region is counted up at a clock cycle of every 1 second.

Next, the MPU 91 repeatedly determines whether the current time has been input by operating the switch group 10 (S2) and determines whether the power switch 7 has been turned on (S3).

After setting the battery 6, when the user operates the switch group 10 to set the current time, the MPU 91 stores the input current time in the RAM 93 according to the signal input via the input interface 95. The current time counter described above is set in the HM area (S4). This allows the current time recognized by the power on/off controller 9 to be adjusted to the accurate current time.

Next, when the user turns on the power switch 7, the MP
U9 1 detects this in step S3 and instructs decoder section 2 to turn on the power (S5). This power-on instruction is the same as the instruction given to the decoder unit 102 when the power switch 107 is turned on in FIG. As a result, the decoder section 2 issues an instruction to the radio section 1 and the DC-DC converter 8 to start operation, thereby putting them into an operating state. Further, when the DC-DC converter 8 starts operating, power is supplied to the CPU 3, the display section 4, the ROM 5, and the notification section 11, and these also become operational. Next, the MPU 91 of the power on/off controller 9 uses the RAM 93
(
S6). That is, in this embodiment, the power switch 7 is also used as the operation switch I) for clearing the set values of the power-on time setting area M1 and the power-off time setting area M2.

Next, the MPU 91 determines whether or not the power-on time has been manually inputted by operating the switch group IO (S7), and if the power-on time has not been input, the process shifts to the process shown in FIG. do.

On the other hand, when the user operates the switch group 1O to set the power-on time, the MPU 91 stores the input power-on time as the power-on time of the RAM 93 in accordance with the signal input via the human interface 95. It is stored in the setting area Ml (S8), and the process moves on to determining whether or not the manual power at the power-off time has been applied (S9). If the power-off time is not input, the process shifts to the process shown in FIG. 5. Further, when the power-off time is input by operating the switch group 10, the MPU 91 follows the input signal.
The input power-off time is stored in the power-off time setting area M2 of the RAM 93 (SIO), and the process proceeds to the process shown in FIG.

Next, with reference to FIG. 4, the operation when both the power-on time and the power-off time are set by the user will be described.

When the MPU 91 of the power on/off controller 9 shifts to the process shown in FIG. (S21), and in order to cut off the main power of this receiver, which was previously turned on in step S5 of FIG. Give instructions (S
2 2) Accordingly, the decoder section 2
The C-DC converter 8 is instructed to stop operating, and the main power is cut off. Next, the MPU 91 determines whether the current time indicated by the current time counter 1 area has reached the time set in the power-on time setting area Ml (S23), and determines whether or not the switch 7 is turned off (S23). The determination (S24) is repeated. Then, when the current time reaches the set power-on time, it instructs the decoder unit 2 to turn on the power (
S25), turn on the main power. Note that if the NB switch 7 is turned off before the set power-on time,
This is detected in step S24, and the MPU 91 returns to step S2 in FIG.

On the other hand, if it is determined in step S21 that the current time is ahead of the power-on time, the main power has already been turned on in step S5 in FIG. The determination as to whether the time set in M2 has been reached (S26) and the determination as to whether the power switch 7 has been turned off (S27) are repeated. Then, when the current time reaches the set power-off time, it instructs the decoder unit 2 to turn off the power (328), thereby causing the main power to be turned off. Note that if the user turns off the T4 source switch 7 before the power-off time, the MPU 91 detects this in step S27 and turns off the power to the decoder unit 2.
F (S29) and disconnects the main TLalg. Then, the process returns to step S2 in FIG.

In FIG. 4, the current time reaches the power-off time and processing 32
After turning off the main power in step 8, the process moves to step S23 and the above-mentioned operation is repeated, so if the power switch 7 is left in the on state, the main power of the receiver can be turned on and off at the same time every day. will be done automatically.

Next, referring to FIG. 5, an explanation will be given of the operation when only the power-on time is set by the user, but the power-off time is not set.

When the MPU 91 of the power on/off controller 9 moves to the process shown in FIG. 5, it instructs the decoder unit 2 to turn off the power and once turns off the main power (S41).

Next, the MPU 91 determines whether the current time indicated by the current time count SI area has reached the time set in the power-on time setting area M1 (S42), and determines whether the power switch 7 is turned off. The determination (343) is repeated. Then, when the current time reaches the set power-on time, it instructs the decoder section 2 to turn on the power (S45) and turns on the main power. Further, if the power switch 7 is turned off before the set power-on time, it is processed in step S4.
3, and the MPU 91 returns to processing S2 in FIG.

When the MPU 91 turns on the main power in step S45, it starts a timer (S46). This timer can be realized by using a certain area of the RAM 93 as a counting area, similar to the current time counting area, and counting and anordinating the value at each reference time. Next, the MPU 9 1 determines whether the value of the timer, that is, the timer time, has become equal to the power-on permissible time WT set in advance in the ROM 92, that is, the time equivalent to the power-on permissible time WT has elapsed since the main power was turned on. The determination as to whether or not the power switch 7 has been turned off (S47) and the determination as to whether or not the power switch 7 has been turned off (348) are repeated. Then, when the timer becomes equal to the power-on permissible time WT, the decoder unit 2G is instructed to turn off the power BoFF to turn off the main power (S49). Therefore, if the power-off time is not set, it is possible to turn on the main power of the receiver for only the power-on permissible time WT stored in the ROM 92 in advance. Note that if the power switch 7 is turned off by the user before the timer measures the power-on permissible time WT, the MPU 91 detects this in the process 34B and instructs the decoder unit 2 to turn off the power ( S50), the process moves to process S2 in FIG.

In FIG. 4, when the main power is turned off in step S49 after the main power has been turned on for the power-on permissible time WT, the main power is turned off in step S42.
, and repeats the above-mentioned operation, so if you leave the power switch 7 on, the receiver's main power will be automatically turned on at the same time every day, and then the power-on permissible time WT will elapse. It will be automatically disconnected afterwards.

Next, referring to FIG. 6, the user can determine the power-on time,
The operation when no Ti source cut-off time is set will be explained.

When the MPU 91 of the power on/off controller 9 moves to the process shown in FIG. 6, it starts a timer (S61). Incidentally, at this point, the main power source is turned on by processing S5 in FIG. 3. Next, the MPU 9 1 sets the timer time to the power-on permissible time WT set in advance in the ROM 92.
(S62), and whether the power switch 7 has been turned off (S62). S63) is repeated. Then, when the timer time becomes equal to the power-on permissible time WT, the decoder unit 2
The main power supply is cut off by instructing the main power supply to be turned off (S6
4). Thereafter, the process waits for the power switch 7 to be turned off (S65), and when the power switch 7 is turned off, the process moves to step S2 in FIG. Furthermore, if the power switch 7 is turned off by the user before the timer measures the power-on permissible time WT, the MPU 91 detects this in step S63,
Instructs the decoder unit 2 to turn off the power (S66),
The process moves to process S2 in FIG. 3. In this way, when neither the power-on time nor the power-off time is set, the main power is turned on from the time when the power switch 7 is turned on until the power-on permissible time WT has elapsed.

The basic operation of this individual selective calling receiver while the main power is turned on is the same as shown in Fig. 7. That is, in a state in which each part is operable in FIG. 1, when a radio signal containing the own calling number is received by the antenna l2,
The radio section 1 amplifies and demodulates the signal, and the decoder section 2 compares the calling number included in the demodulated signal with its own calling number stored in advance in the ROM 5. If there is a loss, the notifying section 11 to notify the user of the call by sound, light, vibration, etc. In addition, if a message is included in the received signal, the decoder unit 2 converts it to the CP
The message is transmitted to U3, and CPU3 displays the message on display unit 4.

〔Effect of the invention〕

As explained above, in the individual selective calling receiver of the present invention, if the power-on time and power-off time are set in advance, the main power is automatically turned on and off at the set times. (1) By setting the power on time and power off time once, the user is freed from the hassle of turning on and off the power switch at a fixed time every day. (2) Since the main power is automatically turned on at the preset time, there is no risk of missing important reception notifications due to the main power not being turned on.

(3) Since the main power is automatically turned off at a preset time, the receiver does not continue to operate with the main power on during unnecessary times, extending the receiver's battery life. be able to.

Effects such as this can be obtained.

In addition, if you only set the power-on time and do not set the power-off time, the main power will be turned on automatically at the set power-on time, and then the main power will be automatically turned on when the preset allowable power-on time has elapsed. It becomes possible to cut.

Furthermore, the power-on time. If no power-off time is set, the main power can be turned on for a preset allowable power-on time from the time the TUB switch is turned on.
