Abstract

PURPOSE:To attain sure notice by measuring the time from the start of ring tone and switching the ring tone pattern after a prescribed time elapses and keeping the notice of the presence of an incoming call while reducing waste current consumption even when a call signal is received in the absence of the possessor of the device. CONSTITUTION:When a call signal is received, a ring tone pattern generation means 2 generates the 1st pattern with a short ring tone interval and an informing means 4 rings in the 1st ring pattern. When the possessor operates a switch 5, a control means 7 is stopped by the count of a timer circuit 6 to stop the ring tone pattern generating means 2. If the possessor is absent and the ring tone is not stopped by the switch operation and when a prescribed time elapses, the timer circuit 6 switches the ring tone pattern of the ring tone pattern generating means 2 from the 1st to the 2nd ring tone pattern and the informing means continues the 2nd ring tone pattern. Thus, the current consumption is suppressed to be low to attain sure information.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a selective call receiving device using radio waves.

BACKGROUND OF THE INVENTION Conventionally, this type of selective call receiving device generates a ringing pattern upon receiving a single ringing signal, and the ringing is stopped by operating a switch or after a predetermined period of time has elapsed. It is configured as follows.

Problems to be Solved by the Invention However, in the conventional selective call receiving device described above, if a call signal is received while the holder is temporarily away from the device and the ringing starts, the user cannot operate the switch. If the device is of a type that stops when the holder returns, the sound will continue until the holder returns, and since this sound pattern is also one type, the sound time is longer than the stop time, consuming a lot of wasted current. Resulting in.

On the other hand, if the ringer automatically stops ringing, there is a problem in that the holder cannot be notified that a call signal has been received while the user is absent.

The present invention solves these conventional problems, and even if the holder of the device receives a call signal when he or she is not present, the present invention continues to notify the user of the incoming call while minimizing wasteful current consumption. In order to achieve the above-mentioned object, the present invention provides a selective call receiving device that can reliably notify the user. A sound pattern generation means for generating a sound pattern, a notification means for making a sound with the sound pattern generated by the sound pattern generation means, a switch for stopping the sound by an external operation, and a sound pattern generating means for generating a sound pattern; a timer circuit for measuring the time from the start of the sound and switching the sound pattern of the sound pattern generating means from the first to the second after a certain period of time has elapsed; It has a pattern generation means and a control means for controlling a timer circuit.

Effects The present invention has the following effects due to the above structure. That is, upon receiving the calling signal, the sound pattern generation means generates a first sound pattern with a short sound interval, and the notification means sounds with this first sound pattern. Here, when the holder operates the switch, the control means stops counting the timer circuit and also stops the sound pattern generation means. In addition, if the holder is not present and the sound is not stopped by operating the switch, the timer circuit changes the sound pattern of the sound pattern generation means from the first to the second sound pattern after a certain period of time has elapsed. , and the notification means continues to sound in this second sound pattern.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings. The figure is a schematic block diagram showing the main parts of a selective call receiving device according to an embodiment of the present invention.

In the figure, a decoder 1 receives a calling signal from a transmitter using an antenna, and decodes the demodulated calling signal using a receiving circuit. Reference numeral 2 denotes a sound pattern generation circuit, which generates a first sound pattern that has a long sound time and a short sound stop time according to the received call signal, and a sound time that is switched to this first sound pattern. A second sound pattern with a short sound stop time and a long sound stop time is generated. 3 is a switching circuit for switching the sound pattern of the sound pattern generation circuit 2; 4 is a speaker which is a means for audibly announcing the first or second sound pattern; and 5 is a switch for stopping the sound. , 6 is a timer circuit for measuring the time from the start of the sound and switching the sound pattern of the sound pattern generation circuit 2 from the first sound pattern to the second sound pattern after a certain period of time has elapsed;
is a control circuit that controls the sound generation pattern 2 and the timer circuit 6 by receiving the call signal and operating the switch 5.

Next, the operation of the above embodiment will be explained.

The demodulated signal from the receiving circuit is decoded by the decoder 1,
If the data matches the data stored in the memory circuit in advance, the sound pattern generation circuit 2 operates. At the same time, the control circuit 7 resets the timer circuit 6 and starts counting. The sound pattern generation circuit 2 first generates a first sound pattern with a long sound time and a short sound stop time, and outputs it to the speaker 4 via the switching circuit 3. Sounds in a sound pattern. When the switch 5 is operated by the holder before the timer circuit 6 counts up to a preset value, that is, before a certain period of time has elapsed, the control circuit 7 stops counting the timer circuit 6 and simultaneously generates a sound pattern. Stop circuit 2. Therefore, the sound from the speaker 4 stops. When the holder is absent and the switch 5 is not operated and the timer circuit 6 counts up, the sound pattern output from the sound pattern generation circuit 2 to the speaker 4 is changed to the first sound by the switching circuit 3. The pattern is switched to a second sounding pattern in which the sounding time is short and the sounding stop time is long, and the speaker 4 sounds in this second sounding pattern.

Effects of the Invention As described above, according to the present invention, when a calling signal is received, the sound pattern generation means generates a first sound pattern with a short sound interval, and the notification means generates a first sound pattern with a short sound interval. Sounds in a pattern. Here, when the holder operates the switch,
The control means stops counting the timer circuit, and
Stop the sound pattern generation means. In addition, if the holder is not present and the sound is not stopped by operating the switch, the timer circuit changes the sound pattern of the sound pattern generation means from the first to the second sound pattern after a certain period of time has elapsed. , and the notification means continues to sound in this second sound pattern. Therefore, the current consumption can be suppressed to a low level and reliable notification can be made.
