Abstract

PURPOSE:To reduce power consumption and to extend the battery service life by setting a notice time with only a light at the arrival of a call. CONSTITUTION:A notice section 13 is provided with a means, which generates a light over a preset time when the notice section 13 is started by a decoder section 4 and generates a sound succeedingly. With a changeover switch 6 thrown to the position of 'N', a signal from the changeover switch 6 to the decoder 4 is logical H and the decoder 4 discriminates it that the notice means is an LED 10 and a speaker 12. When a carrier selects the position 'N', a driver 9 stimulates the LED 10 at the same time of the reception and drives and sounds the speaker 12 together with stimulation after a preset time (t sec). Thus, the power consumption required for the confirmation of a call is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applied to a radio selective call receiver. In particular, it relates to a notification means using light and a sound that increases the ringing tone at regular intervals.

〔overview〕

The present invention is a selective calling means of a wireless receiver that generates light for a preset period of time and then generates sound, thereby making it possible for the carrier to reliably recognize the incoming call.

[Conventional technology]

As shown in FIG. 3, the notification means of a conventional wireless selective calling receiver that increases the ringing tone at regular intervals sends an optical notification (for example, L
ED flashing) and sound notification are performed simultaneously, and the notification sound increases at regular intervals, and after increasing several times, it sounds at maximum volume.

[Problem that the invention seeks to solve]

As described above, the conventional example having a means for increasing the ringing tone sequentially has the disadvantage that even if the carrying person can confirm the call only by the light notification, the ringing tone still sounds and the power consumption increases.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless selective call receiver that eliminates such drawbacks and can reduce power consumption required for confirming a call.

[Means for solving problems]

The present invention includes: a receiving unit that modulates a carrier wave modulated with a signal including a calling number; a notification unit that generates a stimulus including light and sound that can be recognized by the person carrying the device when a call arrives; In a wireless selective calling receiver, the radio selective calling receiver includes a decoder unit that compares the calling number included in the demodulated carrier wave with a calling number stored in the own device and activates the notifying unit when they match. is characterized in that it includes means for generating light and subsequently generating sound for a preset period of time when activated by the decoder section.

Here, the notification section may include means for increasing the volume of the generated sound over time.

Furthermore, the notification section may include means for generating vibrations that can be recognized by the wearer as a stimulus to the wearer.

[Effect]

When a mobile radio receiver receives a call, it emits light and then sounds for a preset period of time. This makes it possible to ensure that the person carrying the phone is aware of the incoming call.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of this embodiment. a receiving section 3 composed of an antenna 1 and a radio section 2;
Decoder 4, reset switch 5, and changeover switch 6
, power switch 7, ROM 8, driver 9, LE
It is composed of a D (light emitting diode) IO, a notification section 13 consisting of a vibrator 11 and a speaker 12. That is, this embodiment includes a receiving section 3 that demodulates a carrier wave modulated with a signal including a calling number, and a notification section 1 that generates a stimulus including light and sound that can be recognized by the person carrying the device when a call arrives.
3, and a decoder 4 which is a decoder section that compares the calling number included in the demodulated carrier wave with the calling number stored in the own device and activates the notification section 13 when they match.
Further, as a feature of the present invention, the notifying section 13 includes means for generating light for a preset period of time and subsequently generating sound when activated by the decoder section. In addition, the notification section 1
3 includes means for generating vibrations that can be recognized by the wearer as stimulation to the wearer. The notification unit 13 also includes means for increasing the volume of the generated sound over time.

Next, the operation of this embodiment will be explained using FIGS. 1 and 2.

A radio signal received by the antenna 1 is amplified and demodulated by the radio section 2, and is input to the decoder 4 as a signal including a calling number. The decoder 4 determines whether or not its own calling number previously written in the ROM 8 matches the received calling number. If the calling numbers match, the decoder 4 outputs to the driver 9 a signal necessary for making a notification at the notification time and volume specified in the ROM 8. When the selector switch 6 is connected to "N", the logic of the signal from the selector switch 6 to the decoder 4 is in a high state, and the decoder 4 indicates that the notification means is L E DIO.
and speaker 12. When the selector switch 6 is set to "M", the signal to the decoder becomes low, and it is determined that the notification means is the LEDIO and the pie break 11. When the wearer selects "N", the driver 9 causes the L E DIO to emit light at the same time as reception as shown in Fig. 2, and after a preset time (seconds) elapses, the driver 9 emits light and drives the speaker 12. , make a sound. The volume of the speaker 12 increases sequentially in four stages at regular intervals, and then reaches the maximum volume. When the carrier presses the reset switch 5, the signal to the decoder 4 becomes low, and the decoder 4
determines that the notification has stopped and stops the drive signal to the driver 9. Through the above operations, the carrier is notified of the incoming call.

FIG. 4 is a flowchart showing the operation of this embodiment. First, the carrier turns on the receiver (step So). The receiver determines whether or not there is an incoming call (step S1), and if there is no incoming call, it repeats the state of waiting for reception.

When there is an incoming call, the notification means is the pie break 11 (when the selector switch 6 is set to "M") or the speaker 1.
2 (when the selector switch 6 selects "N") (step S2); if the selector switch 6 selects "M", the L E DIO and vibrator 11
(Step S3), and the notification is repeated until the person carrying the receiver presses the reset switch 5 (Step S4).
. If the switching switch is "N", first the LEDIO starts blinking, and at the same time, a timer of t seconds (arbitrarily set) is started (step S5). When the carrier learns of the notification and checks whether the reset switch 5 has been pressed (Step S6), if it has been pressed, it returns to the state of waiting for reception; if it has not been pressed, when the timer exceeds t seconds,
Step S7), and the speaker 12 starts producing sound (Step S8). Next, in order to increase the volume in stages, a square counter K is set to 0 (step S9). Then start a 3 second timer (step 510)
. It is determined whether the carrier has pressed the reset switch 5 (step 511). If the user presses the reset switch 5, the device waits for reception; if the user does not press the reset switch 5, the 5-second timer continues to operate. When the timer exceeds 3 seconds (step 512), the volume of the speaker 12 is increased (step 513). 1 to the value in the counter
is added (step 514), and the volume is sequentially increased until K reaches 3 (step 515). If K becomes 3 and the reset switch 5 is pressed while sounding at the maximum volume, the device returns to the state of waiting for reception, and if it is not pressed, the sound continues at the maximum volume (step 315). In this embodiment, although the notification sound increases sequentially, the notification can be performed even if the notification sound has a constant volume.

〔Effect of the invention〕

As explained above, by setting the notification time using only light when a call arrives, the present invention reduces power consumption and reduces battery consumption compared to conventional wireless selective calling receivers in which the ringing tone increases at regular intervals. It has the effect of extending lifespan.
