DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective calling receiver, and more particularly to an improvement of a clock setting function in a radio selective calling receiver with a clock function.

[0002]

2. Description of the Related Art A radio having a display function of notifying a call in a form such as blinking of an LED or sounding of a speaker by receiving a signal including a self-selected call number and displaying a message included in the received signal on a display device. Selective call receivers have been practically used. As a further extension of the function of such a receiver, there has been reported a wireless selective call receiver with a clock function having a clock function for displaying time on a display device.

In such a wireless selective call receiver with a clock function, so-called time adjustment is required. For this reason, the conventional wireless selective call receiver with a clock function is provided with two switches. 1
First, the wireless selective call receiver is shifted to the clock setting state, the time value of the current change target is changed from, for example, a value representing hours to a value representing minutes, or the time after the change is completed by terminating the clock setting state. Is a switch for setting the clock function as a clock function, and the other is a switch for increasing or changing by a unit time in order to adjust the time value of the current change target to an accurate time.

[0004]

Conventionally, time setting was made possible by providing two switches as described above. However, since at least two switches are required, the tendency has been further strengthened in recent years. This has been a major obstacle to miniaturization of the radio selective calling receiver.

Accordingly, a first object of the present invention is to make it possible to switch the current time value to be changed and to increase or decrease the current time value to be changed with one switch. is there.

A second object of the present invention is to make it possible to instruct the transition to the clock setting state by using the switch.

A third object of the present invention is to make it possible to further instruct the end of the clock setting state with the switch.

[0008]

In order to achieve the first object, the present invention provides a radio selective call receiver having a clock function for displaying time on a display A, as shown in FIG. Switch B having a first state and a second state
And a timer C for counting the time during which the switch B keeps the second state, and the duration of the second state counted by the timer C during the clock setting state is shorter than the first time. The time change means D for changing the time value of the current change target displayed on the display A by a unit amount, and the continuation time of the second state measured by the time keeping means C during the clock setting state. A change target switching means E for switching the current change target to another time value when the time is equal to or longer than the first time is provided.

Further, in order to achieve the above-mentioned second object, the switch B is turned on within a second time from the power-on.
And the clock setting state starting means F for setting the receiver to the clock setting state when the continuation time measured by the timer means C is equal to or longer than the third time.

Further, in order to achieve the third object, the second time measured by the clock means C in a state where the time value of the current change object is the time value of the last change object.
When the continuation time of the state becomes equal to or longer than the first time, a clock setting state ending means G for performing clock setting and terminating the clock setting state is provided.

In a preferred embodiment of the present invention, the operability is improved by setting the first time, the second time, and the third time to be the same time. The clock setting state start means F sets the time value of the current change target to a time value to set the receiver in the clock setting state, and the change target switching means E measures the time in a state where the time value is the current change target. When the continuation time of the second state measured by the means C is equal to or longer than the first time, the current change target is switched to a numerical value representing the minute, and the clock setting state ending means G changes the numerical value representing the minute to the current change target. In the state where
When the continuation time of the second state measured in step 1 is equal to or longer than the first time, the clock setting is performed and the clock setting state is ended.

[0012]

In the radio selective call receiver with a clock function of the present invention, if the switch B is set to the second state within the second time after the power of the receiver is turned on and the switch B is maintained for the third time or more, the clock The setting state starting means F puts the receiver in a clock setting state, for example, and flashes a numerical value indicating the time displayed on the display A to notify the operator that the current change target is the time. In this state, when the operation of setting the switch B to the second state for less than the first time is repeated, the time changing means D increases or decreases the time value representing the hour by one hour, for example. After adjusting the time value, switch B
When the second state is set for more than the time, the change target switching means E
Switches the current change target from a numerical value representing the hour to a numerical value representing the minute, for example, and makes it blink. In this state, switch B
Is repeated for less than the first time, the time changing means D increases or decreases the time value representing the minute by one minute, for example. When the switch B is set to the second state for the first time or more after the minute value is also adjusted, the clock setting state ending means G sets the clock to restart the clock function from the time at which the time has been adjusted, and Terminate the clock setting state.

Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 2 is a block diagram showing a hardware configuration example of the wireless selective call receiver with a clock function according to one embodiment of the present invention.

As shown in FIG. 2, the radio selective call receiver with a clock function of the present embodiment comprises an antenna 1, a radio section 2,
Waveform shaping circuit 3, decoder unit 4, ID memory 5, CPU
6, memory 7, driver unit 8, LED 9, speaker 1
0, an LCD driver 11, an LCD 12, a main switch 13, and a push switch 14. The wireless selective call receiver with a clock function according to the present embodiment performs a call notification by receiving a signal including its own selective call number and displays a message included in the received signal. In addition to the original functions of the device, the device has a clock function for displaying the current time on the LCD 12. The main part of such a clock function is built in the decoder unit 4, and the CPU 6 receives a time information signal output from the decoder unit 4 and
The current time is displayed on the LCD 12 by controlling the CD driver 11.

FIGS. 3 to 5 are flowcharts showing an example of the time adjustment operation in the present embodiment, which is mainly executed by the decoder unit 4 in FIG. FIG. 6 shows a display example of the LCD 12 during the clock setting state. Hereinafter, the operation of this embodiment will be described with reference to the drawings.

In FIG. 2, the main switch 13 is a slide switch. When the main switch 13 is operated to slide from the power OFF side to the ON side, the power is turned on to the wireless device (S1 in FIG. 3).

When the power is turned on, the decoder unit 4 starts a counter provided therein (S2), and determines whether or not the push switch 14 is pressed before the counter counts 2 seconds (S3). , S6). If the push switch 14 is depressed within that time, the process proceeds to step S7. If the push switch 14 is not depressed, the counter is stopped (S4), and the mode shifts to the normal operation state (S4).
5).

The operation in the normal operation state is the same as in the conventional case. That is, the wireless device is in a signal waiting state,
A radio signal received by an antenna 1 is amplified and demodulated by a radio unit 2 and converted into a digital signal by a waveform shaping circuit 3.
When input to the decoder unit 4, the decoder unit 4 collates its own selected call number stored in the ID memory 5 with the selected call number in the digital signal, and notifies the CPU 6 if they match. . If a message is included in the digital signal, the message is notified to the CPU 6. When the CPU 6 receives from the decoder unit 4 a notification indicating that it has received a signal including its own selected call number, the CPU 6 applies a control signal to the driver unit 8 to make a call notification in the form of blinking of the LED 9 and sounding of the speaker 10. . When receiving the message, the control unit 10 applies a control signal to the LCD driver 11 to display the received message on the LCD 12. Also, the received message is stored in the memory 7 in preparation for redisplaying the message later. It should be noted that the call notification is made during the notification by the push switch
Can be stopped by pressing. The ringing sound of the speaker 10 is controlled by the main switch 13.
Can be switched by sliding to the strong sound side or the weak sound side. Further, the message stored in the memory 7 can be displayed again on the LCD 12 by pressing the push switch 14 at the time when the message can be displayed again.

On the other hand, the decoder unit 4 has a push switch 1
If the process proceeds to step S7 due to the button 4 being pressed within 2 seconds after the power is turned on, the counter is reset once and restarted (S7). (S8), the counter is stopped (S9). That is, the pressing time of the push switch 14 is measured. Then, it is determined whether the time counted by the counter is 2 seconds or more (S1).
0) If it is 2 seconds or more, the process proceeds to step S11 in FIG. 4 to enable time adjustment, and if not, the process shifts to a normal operation state (S5).

In step S11, the decoder unit 4 sets the receiver in a time adjustment mode. That is, information about the current time of the clock function is notified to the CPU 6 and the
Is displayed under the control of the CPU 6, and the numerical value representing the hour is blinked under the control of the CPU 6 to notify the operator that the time adjustment mode has been entered.

FIG. 6A shows the LCD 1 in the time adjustment mode.
2 shows a time display example, in which a numerical value 21 indicating hour (in the display example, 16:00 is indicated) is blinking. The arrows in the figure indicate that the display is blinking, and are not actually displayed.

With the receiver in the timed mode,
When the push switch 14 is pressed (YE in S12)
S), the decoder unit 4 starts a counter (S1).
3) Then, the timing at which the push switch 14 is turned off is captured (S14), and the counter is stopped (S15) to measure the pressing time of the push switch 14. If the time counted by the counter is not 2 seconds or more (NO in S16), the numerical value representing the hour is increased by one hour (S17). That is, for example, when the push switch 14 is pushed one time for a short time in the state of FIG. 6A, the numerical value “16” representing the hour is incremented by one to “17”. The operator repeats the above-described operation of the push switch 14 as necessary to set the numerical value of the hour to a desired value.

If the decoder unit 4 determines in step S16 that the push switch 14 has been pressed for more than 2 seconds, the process proceeds to step S18 in FIG. 5, and the receiver is set to the sorting mode. At this time, as shown in FIG. 6B, the numerical value 22 representing the minute (the display example represents 03 minutes) flashes to notify the operator that the mode has been set to the minute setting mode.

In this state, if the push switch 14 is pressed (YES in S19), the decoder unit 4 starts a counter (S20), and then the push switch 14
The timing at which the switch is turned off is captured (S21), and the counter is stopped (S22) to measure the pressing time of the push switch 14. If the time counted by the counter is not 2 seconds or more (NO in S23), the numerical value representing the minute is increased by one minute (S24). The operator pushes the push switch 14 a required number of times to set the numerical value of the minute to a desired value.

When the decoder unit 4 determines that the push switch 14 has been pressed for two seconds or more in step S23, the decoder unit 4 sets the clock function inside the decoder unit 4 at the set time (the time currently displayed on the LCD 12). (S2
5) The clock setting state is ended (S26), and the operation shifts to the normal operation state (S5).

As described above, according to the radio selective calling receiver with a clock function of this embodiment, one push switch 1
Various operations related to time adjustment can be performed in step 4.

As described above, the radio selective call receiver with a clock function according to the present invention comprises a switch, a clock means, a time changing means, and a change target switching means. Switching of the target time value and change such as increase or decrease of the current time value of the change target can be performed.

Further, by providing the clock setting state starting means, it is possible to shift the receiver to the clock setting state by the switch.

Further, by providing the clock setting state ending means, the clock setting state can be further ended by the switch.

As described above, according to the present invention, various operations relating to time adjustment can be performed with one switch, so that the size of the radio selective calling receiver can be further reduced as compared with the related art which requires at least two switches. Can be
In addition, cost can be reduced.
