Definitions
- the present invention relates to a radio pager having a timepiece function and, more particularly, to a data display radio pager having a timepiece function and allowing the user of the pager to perform various kinds of time setting operations on a single operation switch.
- a data display radio pager It is a common practice with a data display radio pager to alert, on receiving a call signal including an address assigned to the pager, the user to the call by causing an LED (Light Emitting Diode) to flash, causing a louspeaker to produce an alert tone, or causing a vibrator to vibrate.
- this kind of pager displays a message also included in the call signal on a display.
- An advanced type of data display radio pager additionally has a timepiece function for displaying time on the display. Such an advanced pager has to have the time thereof set and, therefore, usually has two operation switches. Specifically, one operation switch is used to set up a time set mode, to replace the numerical value to be changed, e.
- an object of the present invention to provide a data display radio pager with a timepiece function which allows the user to switch over the numerical value to be changed, and decrement or decrement it on a single operation switch.
- a data display radio pager having a timepiece function of the present invention comprises a single operation switch having a first and a second state, a counter for counting the period of time during which the operation switch remains in the second state, a time changing section for changing, when the period of time counted by the counter in a time set mode is shorter than a first predetermined period of time, a numerical value representative of a component of time to be changed and appearing on a display by a unit amount, and a time component replacing section for replacing, when the period of time counted by the counting means in the time set mode is equal to or longer than the first period of time, replacing the numerical value to be changed with another numerical value representative of another component of time.
- the pager includes a display A for displaying time, a single operation switch B having a first and a second state, and counting means C for counting the period of time for which the switch B remains in the second state.
- time changing means changes a numerical value representative of the component of current time appearing on a display A and to be changed.
- Component replacing means E replaces the numerical value representative of the component to be changed with another numerical value when the duration of the second state counted by the counting means in the time set mode is equal to or longer than the first period of time.
- Time set mode starting means F sets up a time set mode when the operation switch B is brought to the second state within a second period of time after the turn-on of the power source and the duration of the second state is equal to or longer than a third period of time.
- time set mode ending means G sets time and ends the time set mode when the duration of the second state is equal to or longer than the first period of time and the component of time to be changed is the last component.
- FIG. 2 shows a specific hardware construction of the embodiment.
- the pager has an antenna 1, an RF (Radio Frequency) section 2, a waveform shaper 3, a decoder 4, an ID (Identification) memory 5, a CPU (Central Processing Unit) 6, a memory 7, a driver 8, an LED (Light Emitting Diode) 9, a loudspeaker 10, an LCD (Liquid Crystal Display) driver 11, an LCD 12, a slide type main switch 13, and a push type operation switch 14.
- the pager alerts the user to the call in response to an address signal included in the call signal, while displaying a message in response to a message signal also included in the call signal.
- the pager has a function of displaying current time on the LCD 12. Such a function is incorporated in the decoder 4.
- the CPU 6 receives time information from the decoder 4 and displays it on the LCD 12 by controlling the LCD driver 11.
- FIGS. 3-5 demonstrate a specific time setting operation to be executed by the embodiment, mainly by the decoder 4, FIG. 2.
- FIGS. 6A and 6B each shows a specific condition of the LCD 12 occurring when the time setting operation is under way. The operation of the pager shown in FIG. 2 will be described with reference to FIGS. 3, 4, 5, 6A and 6B.
- step S1 As the main switch 13, FIG. 2, is slid from an OFF position to an ON position, a power source included in the pager is turned on (step S1, FIG. 3). On the turn-on of the power source, i.e. triggered thereby, the decoder 4 starts a counter, not shown, incorporated therein (S2). The decoder 4 determines whether or not the operation switch 14 has been pushed before the counter counts two seconds (S3 and S6). If the answer of the step S6 is positive, YES, the program advances to a step S7. On the other hand, if the answer of the step S3 is positive, YES, The decoder 4 stops the counter (S4), and the operation mode is restored to ordinary one (S5).
- the ordinary mode operation, S5, will be described with reference to FIG. 2.
- the pager awaits a call signal.
- a call signal coming in through the antenna 1 is amplified and then demodulated by the RF section 2.
- the modulated signal from the RF section 2 is converted to a digital signal by the waveform shaper 3 and then applied to the decoder 4.
- the decoder 4 compares an address included in the digital signal with the address stored in the ID memory 5 and assigned to the pager. If the two addresses are coincident, the decoder 4 informs the CPU 6 of the coincidence. At the same time, if the call signal includes a message, the decoder 4 transfers it to the CPU 6.
- the CPU 6 feeds a control signal to the driver 8 to cause the LED 9 to flash or to cause the loudspeaker 10 to produce an alert tone.
- the CPU 6 displays it on the LCD 12 by delivering a control signal to the LCD driver 11.
- the CPU 6 stores the received message in the memory 7 so that it may be displayed again in the future, as desired.
- the operation switch 14 may be pressed to stop the alerting operation while the latter is under way.
- the main switch 13 is slidable toward the higher side or the lower side to adjust the loudness of the alert tone to come out from the loudspeaker 10.
- the message stored in the memory 7 will appear on the LCD 12 again as the user presses the operation switch 14 later.
- the decoder 4 once resets the counter and then starts it again (S7). Subsequently, as soon as the operation switch 14 is released or turned off (S8), the decoder 4 stops the counter (S9) to thereby determine the period of time for which the switch 14 has been pushed. The decoder 4 determines whether or not the time counted by the counter is two seconds or longer (S10) and, if the answer is positive, executes a step S11, FIG. 4, for allowing the user to set time. If the answer of the step S10 is negative, NO, the operation is transferred to the step S5.
- the decoder 4 sets up an hours set mode. Specifically, the decoder 4 transfers information relating to current time to the CPU 6. Then, the CPU 6 displays current time on the LCD 12. At the same time, the CPU 6 causes, among the numerical values each showing a particular time component, the numeral value representative of hours to flash on the LCD 12, thereby informing the user of the fact that the hours set mode has been set up.
- FIG. 6A shows specific time appearing on the LCD 12 in the hours set mode; the numerical value "21" (indicative of sixteen hours) is flashing. It should be noted that arrows shown in FIG. 6A simply indicate that the numeral 21 is flashing and do not appear in practice.
- the decoder 4 starts the counter (S13) and then stops it (15) when the switch 14 is turned off (S14), thereby determining the period of time for which the switch 14 has been pushed (S16). If the determined period of time is shorter than 2 seconds, (NO, S16), the numerical value representative of hours is incremented by one hour (S17). Specifically, when the switch 14 is pushed once for a short period of time in the condition shown in FIG. 6A, the numerical value "16" indicative of hours is incremented by one to "17". The user may repeat such a procedure until a numerical value representative of desired hours appears on the display LCD 12.
- the decoder 4 determines that the operation switch 14 has been continuously pressed for two seconds or more, it executes a step S18, FIG. 5, for setting up a minutes set mode. Then, as shown in FIG. 6B specifically, the numerical value 22 (indicative of three seconds) flashes to show the user that the minutes set mode has been set up.
- the decoder 4 starts the counter (S20) and then stops it (S22) when the switch 14 is released or turned off (S21), thereby determining the duration of the pushed state of the switch 14. If the determined duration is short of two seconds (NO, S23), the decoder 4 increments the numerical value 22 by one minute (S24).
- the decoder 24 sets the timepiece function thereof to the time having been set (i.e. time appearing on the LCD 12) (S25). Thereafter, the decoder 4 ends the time setting operation (S26) and then resumes the ordinary mode operation, S5.
- the present invention provides a data display radio pager having a single operation switch, time counting means, time changing means, time component replacing means, time set state starting means, and time set state ending means.
- the radio pager therefore, can replace the time of current time to be changed, increase or decrease the time component of interest, and start and end the time setting state, by the single switch. This is successful in further reducing the size and cost of the above-described type of pager which has customarily been provided with at least two switches.
