DETAILED DESCRIPTION OF THE ~I~ 'hKKl~;lJ EMBODIMENT
The present invention will be described below with 25 reference to the embodiment shown in the a~:~ ylng ," ,, 21900~S
drawings .
,' Flg. 1 is a block diagram showing the arrangement of a radio selective calling receiver accordlng to an ~ t of the present invention . Note that a dlsplay unit ( LCD ) 8A
as the flrst example of the dispIay unit ln this embodiment shows a detailed display sample.
The radio selective calling receiver in Fig. 1 re-celves, through an antenna 1, a radlo selectlve call signal from a base statlon in the paging system to which the recelver belongs. This radio selective call signal is ted and ~;UIIV~ ~d into a digltal signal by a radio unit 2. This digital signal is input to a microprocessor ( CPU ) 3 . The CPU 3 decodes the digital signal and compares the selective call si~nal contained therein with the self-selective call number written in a ROM 4. When they r~o~ nn~ with each other, the CPU 3 stores the message slgnal contained in the digital signal and following the selective call slgnal in the built-ln memory, and drives a loudspeaker 6 to generate a sound, thereby notifying the callee, i.e., the user of thls recelver, of the call.
When the user is to check the above message after the notification of the call, he/she operates a switch 5 to set the message dlsplay mode ln the CPU 3, thereby causlng the CPU 3 to perform message dlsplay control. In the message display mode, the CPU 3 dlsplays the message correspondlng , 21gO~55 to the message signal stored in the built-in memory on a message display screen 81 of an LCD 8A. Note that the message display screen 81 in Fig. 1 includes a dot matrix display screen for displaying messages, an~ a multi-screen indicator 82 for time-out display Ito be described later).
Similar to receivers using conventional techniques, this radio ~elective calling receiver allows the user to set various functions, e.g., time-of-day setting, alarm setting, stereotyped expression registration, and reception area setting by operating the switch 5 . In a predetl~rm1 n~(l function setting operation, the CPU 3 displays the set UUlll.UIll,~l of the function on the message display screen 81 of the LCD 8A, like the display sample "*PAGER ûN*" in Fig. 1.
In setting the above functions, if the user does not operate the switch 5 within a predet~rml nF-rl tlme interval ( time-out time) for each setting operation (a time out occurs), the CPU 3 au~ l_lcally shifts the operation mode to the call wait state, i.e., performs time-out control.
The above time-out control will be described in detail.
In the function setting mode, when the switch 5 is operated, the CPU 3 sets a prede~c~rm1 nf:.~ time-out time for the function to be set, and starts a timer 7 to count an elapsed time until the end of the time-out time. When the switch 5 is operated within the time-out time, the CPU 3 resets the timer 7 to cause it to start counting again. The CPU 3 2190~5~
causes the lndicator 82 to display the counted time.
to the dl~play sample in Fig. l, as the time is counted, the black portions of the indicator 82 reduces.
When the tlme-out time is counted ( a time out occurs ), all the display portions of the indicator 82 change from black to white. That is, countdown display is p~LL~
When the end of the time-out time approaches, i.e., about one black dlsplay portion of the indlcator 82 is left, the CPU 3 causes the lo~ r~k~r 6 to generate a sound to warning about a time out. This warning by means of sound can be easily recognlzed lf the form of producing this sound is different from that of call notiflcatlon. Note that the CPU 3 may warn about a tlme out by f llckering the message display screen 81 or changing the display symbols together with the above warning by means of sound.
As described above, the radio selective calling receiver of this ' ~ t performs warning by means of sound or warning by means of display near the end of the tlme-out tlme in the function setting mode. Therefore, the function setting mode does not end abruptly, and the operatlon of the function setting switch ls clarlfied. In addition, since countdown display of the time until a time out is p~L r~ ~ in the above warning operation by means of display, the user can lmmediately r~rogn~ ~e the margin time allowed for the operatlon of the switch 5.
~ -', 2l90a~s Fig. 2 shows the display surface of a display unit ( LCD ) 8B as the second example o~ the display unit in this embodiment .
This LCD 8B lncludes a message display screen 81 5 identical to that of the LCD 8A, and a segment display unit 83 for displaying the time counted by the timer 7 by operating 7-segment display Pl ~ Ls. The segment display unit 83 can perform 7-segment display, and i8 displaying "14" s (seconds) in Fig. 2. As the end of the time-out time approaches, the CPU 3 displays a smaller number. At the end of the time-out time, the CPU 3 displays the number "0" to notify the user of the time out. This warning about a time out by means of 7-segment display provides the same effect as that provided by the warning operation by means of display in Fig. 1.
Fig. 3 is a flow chart showing a time-out control operation in the ' ~ t in Fig. 1. Referring to Fig. 3, the tlme-of-day setting mode is set. That is, in this case, "hour", "minute", and "second" are set as the time of day in this radio selective calling receiver.
First of all, the user operates the switch 5 to cause the CPU 3 to start the time-of -day setting mode ( step 101 ) .
The CPU 3 then presets the timer 7 for counting an elapsed time until a time-out time T0 for "hour" setting (step 102).
At the same time, the CPU 3 causes the indicator 82 to .
~,~ 21900~5 display the elapsed time until the time out T0, and causes , ' the timer 7 to start a countdown operation ( step 103 ) . Note that the CPU 3 causes the indicator 82 to display the elapsed time by properly dividing the plurality of display portions in accordance with the elapsed time until the time-out time T0.
When the user depresses the switch 5a ;lqq~nF-l as a "time" setting switch (to be referred to as a "time" setting switch hereinafter) (YES in step 104), the CPU 3 performs "hour" setting (step 108). (In the actual receiver, the user must operate the switch 5 for ad~ustment to an arbi-trary time before depressing the "time" setting switch 5a.
However, this operation is not directly associated with the present invention, and hence a description thereof will be omitted). If it is rlPt~rmlnF.~l in step 104 that the "time"
setting switch 5a is not depressed ( N0 in step 104 ), the flow advances to step 105 . The CPU 3 then detF~rml nC..q the elapsed time from the start of monitoring of the timer 7 to the time-out time T0 ( steps 105 to 107 ) . That is, the CPU

This LCD 8B lncludes a message display screen 81 5 identical to that of the LCD 8A, and a segment display unit 83 for displaying the time counted by the timer 7 by operating 7-segment display Pl ~ Ls. The segment display unit 83 can perform 7-segment display, and i8 displaying "14" s (seconds) in Fig. 2. As the end of the time-out time approaches, the CPU 3 displays a smaller number.

This warning about a time out by means of 7-segment display provides the same effect as that provided by the warning operation by means of display in Fig. 1.
Fig. 3 is a flow chart showing a time-out control operation in the ' ~ t in Fig. 1. Referring to Fig. 3, the tlme-of-day setting mode is set. That is, in this case, "hour", "minute", and "second" are set as the time of day in this radio selective calling receiver.
First of all, the user operates the switch 5 to cause the CPU 3 to start the time-of -day setting mode ( step 101 ) .
The CPU 3 then presets the timer 7 for counting an elapsed time until a time-out time T0 for "hour" setting (step 102).
At the same time, the CPU 3 causes the indicator 82 to .
~,~ 21900~5 display the elapsed time until the time out T0, and causes , ' the timer 7 to start a countdown operation ( step 103 ) . Note that the CPU 3 causes the indicator 82 to display the elapsed time by properly dividing the plurality of display portions in accordance with the elapsed time until the time-out time T0.
When the user depresses the switch 5a ;lqq~nF-l as a "time" setting switch (to be referred to as a "time" setting switch hereinafter) (YES in step 104), the CPU 3 performs "hour" setting (step 108). (In the actual receiver, the user must operate the switch 5 for ad~ustment to an arbi-trary time before depressing the "time" setting switch 5a.
However, this operation is not directly associated with the present invention, and hence a description thereof will be omitted). If it is rlPt~rmlnF.~l in step 104 that the "time"
setting switch 5a is not depressed ( N0 in step 104 ), the flow advances to step 105 . The CPU 3 then detF~rml nC..q the elapsed time from the start of monitoring of the timer 7 to the time-out time T0 ( steps 105 to 107 ) . That is, the CPU
3 has set two types of times, i.e., a time-out time T1 for warning about a time out, and a time-out time T2 as the time interval between the end o~ the time-out time T1 to the end of the time-out time T0 (T0 = T1 + T2). If the "time"
setting switch 5a is not depressed before the lapse of the 25 time-out time T1 ( YES in step 105 ), the CPU 3 causes the ,.. ~ 2190055 1 r~ QpF~kf~r 6 to generate a sound to warn about the approach of the end of the time-out tlme T0 ( step 106 ) . As described above, ln step 106, the CPU 3 may warn about the approach of the end of the tlme-out time T0 by ~llckerlng the message dlsplay screen 81 or changing the display symbols together wlth warnlng by means of sound.
If the "tlme" settlng switch 5a is not depressed before the lapse of the tlme-out time T2 after step 106 (YES in step 107 ), the CPU 3 terminates the tlme-of -day setting mode, and the reoeiver is set in the walt state ( step 123 ) .
Note that this wait state includes the call wait state and the message wait state. If the user depresses the "tlme"
settlng switch 5a before the lapse of the tlme-out tlme Tl and the tlme-out time T2, i.e., before YES ls obtalned ln 15 steps 105 and 107, the CPU 3 peL~uLI.. v "hour" settlng, as descrlbed above ( step 108 ) .
When "hour" setting is completed in steps 104 and 108, the flow shifts to the "mlnute" settlng mode. That is, the CPU 3 presets a time-out time for "minute" setting ln the tlmer 7 ( step 109 ) . Subsequently, the user operates the switch 5 to set/lnput data, and the recelver sequentially performs "minute" setting and "second" settlng by the same procedure as that for "hour" settlng (steps 110 to 123).
setting switch 5a is not depressed before the lapse of the 25 time-out time T1 ( YES in step 105 ), the CPU 3 causes the ,.. ~ 2190055 1 r~ QpF~kf~r 6 to generate a sound to warn about the approach of the end of the time-out tlme T0 ( step 106 ) . As described above, ln step 106, the CPU 3 may warn about the approach of the end of the tlme-out time T0 by ~llckerlng the message dlsplay screen 81 or changing the display symbols together wlth warnlng by means of sound.
If the "tlme" settlng switch 5a is not depressed before the lapse of the tlme-out time T2 after step 106 (YES in step 107 ), the CPU 3 terminates the tlme-of -day setting mode, and the reoeiver is set in the walt state ( step 123 ) .
Note that this wait state includes the call wait state and the message wait state. If the user depresses the "tlme"
settlng switch 5a before the lapse of the tlme-out tlme Tl and the tlme-out time T2, i.e., before YES ls obtalned ln 15 steps 105 and 107, the CPU 3 peL~uLI.. v "hour" settlng, as descrlbed above ( step 108 ) .
When "hour" setting is completed in steps 104 and 108, the flow shifts to the "mlnute" settlng mode. That is, the CPU 3 presets a time-out time for "minute" setting ln the tlmer 7 ( step 109 ) . Subsequently, the user operates the switch 5 to set/lnput data, and the recelver sequentially performs "minute" setting and "second" settlng by the same procedure as that for "hour" settlng (steps 110 to 123).
