Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a radio selective call receiver, and more particularly to a receiver capable of informing the setting status of a power switch.

[Prior Art] Conventionally, when a power switch is turned off, a radio selective calling receiver not only stops the operation of a radio unit but also stops a notification function such as a sound and a message display function.

When the clock function is built in, the clock unit continues to operate and maintains the function as a clock even when the power switch is turned off.

[Problems to be Solved by the Invention] In the above-described conventional radio selective call receiver, when the power of the receiver is turned off and the receiver carrier forgets to turn on the power switch in that state, a call is made. However, there is a drawback that the selective call signal cannot be received.

The radio selective calling receiver of the present invention has been made in view of the above problems, and the radio selective calling receiver is configured to notify that the power switch is in the off state to call attention at a certain predetermined time. For the purpose of providing.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a time storing means for storing a predetermined time in a radio selective calling receiver having a clock function and a power switch, and the time storing means. When the stored time is reached, if the power switch is in the off state, a signal is output, and the signal is repeatedly output until the power switch is turned on. The time storage means is preferably an EEPROM.

[Operation] According to the above configuration, when the determination means determines that the power switch is in the off state at the time stored in the time storage means, the notification means can notify the determination result, so that the power is in the off state. You can call attention to what is in.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a radio selective calling receiver according to this embodiment.

The wireless signal received by the antenna 101 is transmitted to the wireless unit 102.
After being amplified by, the signal is demodulated, then converted into a digital signal by the waveform shaping circuit 103, and input to the decoder 104.

The decoder 104 determines whether or not the input signal is a selective calling signal for itself.

That is, its own selective calling address is EEPROM (Elec
trical Erasable Programable Read Only Memory) 105
The selected selective call address, which is stored in the memory, is read by the control unit 106 from the EEPROM 105 and the received selective call address is collated by the decoder 104.

When it is determined that it is the selective calling signal for itself as a result of the collation, the control unit 106 controls the speaker driving circuit 107 to control
A sound is generated by 108, and the LED drive circuit 109 is controlled to blink the LED 110 for notification.

At the same time, the control unit 106 outputs the received message to the LCD drive circuit 111 and causes the LCD 112 to display the message.

The clock obtained by the crystal oscillator 114 is controlled by the control unit 106.
In addition to being used for the operation of, the reference clock of the clock unit 115 is supplied via the control unit 106.

The time data obtained by the clock unit 115 is the normal control unit 106.
Is output to the LCD drive unit 111 and displayed on the LCD 112.

Reference numeral 113 is a battery that supplies power to the receiver, and a power switch 116 is provided on a wire different from the power line of the battery 113. The power switch 116 turns on the power for operating the normal receiving function of the receiver. -A switch for switching off.

That is, if the power switch 116 is closed as a receiver, the normal reception operation is performed in the power-on state, but if the power switch 116 is opened, the reception operation is stopped in the power-off state.

Further, the EEPROM 105 can store a selective calling address of itself and can also set a required time by writing a required time.

The control unit 106 controls the time output from the clock unit 115 and the EEPR
The set time read from the OM105 is constantly checked.

The control procedure in the present receiver having the above configuration will be described with reference to the flowchart in FIG.

First, it is determined whether or not the time is set in the EEPROM 105 (step), and if not set, the step is repeated to wait until the required time is set.

When the time is set, the process proceeds to step, and it is determined whether or not the set time is reached by comparing with the output of the clock unit 115. If the set time is not reached, the step is repeated to reach the set time. Wait for

When the set time arrives, proceed to the step and turn the power switch
It is determined whether 116 is off, and if not off, the process returns to step.

If the power switch 116 is off in step,
Proceed to step to blink LED110 and drive speaker 10
Generates 8 tones. And step ...
As long as the above is repeated, the notification is given and the user's attention can be called.

By this notification, if the user turns on the power switch 116, the process returns from step to step and the notification is stopped.

Since the control is performed as described above, if the power switch 116 is in the off state when the time set in the EEPROM 105 is reached, the speaker 108 emits a sound and the LED 110 blinks. You can call attention.

The receiver carrier who has received the notification notices that he has forgotten to enter the reception state, and can turn on the power switch 116 to enter the reception state and stop the notification.

As described above, according to the present receiver, the time set in the EEPROM 105 can be effectively used by setting it as an arbitrary time in a time zone in which it is highly necessary to keep the reception state.

Also, a plurality of times can be set as necessary.

The set time can be changed by electrically rewriting the stored data in the EEPROM 105.

[Effects of the Invention] As described above, the present invention notifies that the power switch is in the off state at the set time, so if the power switch is forgotten, the selective call signal will be given even if a call is made when necessary. It is possible to avoid the problem that the data cannot be received.

In addition, it is possible to alert the user by notifying that the power switch has been turned off and not being able to receive the signal for a long time.
