Description

TECHNICAL FIELD The present invention relates to a so-called wireless selective receiver such as a pager, and more particularly to a wireless selective receiver used in a small zone.

[Conventional technology]

Conventionally, a wireless selective receiver has been used as a means for communicating with a moving person. This kind of wireless selective receiver
In response to the individual selection signal sent by the wireless line, the carrier is notified of the calling by means of a ringing sound or the like.

[Problems to be solved by the invention]

By the way, it is conceivable to lend such a radio selective receiver for calling a patient in a waiting room of a hospital or calling a customer at a bank window. In such a case, the calling zone is a small zone such as a waiting room or a store. However, in the conventional wireless selective receiver, even if the wearer carries the wireless selective receiver out of the calling zone, the wireless selective receiver does not respond and the carrier unknowingly or intentionally takes it away and loses it. It had the drawback of having the potential.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a wireless selective receiver in which an alarm is issued when a carrier goes out of the calling zone so that the wireless selective receiver is not lost. To aim.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention continuously receives an intermittent start signal and receives a signal transmitted to a predetermined small zone from a transmitter that transmits a calling signal at the time of calling. And a decoder unit that determines whether the received call signal is the same as a preset call signal, and a first alarm that is activated when the same call signal as the predetermined call signal is received. A ringing tone generating circuit for outputting a tone, and a ringing tone generating circuit for outputting a synthesized voice which is a second alarm sound indicating that the user is out of the area when the start signal is not received for a predetermined time or longer. And a timer unit for driving the device, and prompts the wearer to return it by the synthesized voice.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.
An antenna 1 that receives a radio wave is connected to a receiver 2 that demodulates a radio signal. The output of the receiver 2 is supplied to the decoder 4 which decodes the received signal. The decoder unit 4 compares the received signal with the selective call number of the local station set in the selective call number setting unit 3, and if the signal is the local station's ring signal, drives the ringing tone generation circuit 9 and calls from the speaker 10. Produces sound.

Further, the decoder unit 4 is connected to the timer unit 5 as a driving unit by the timer control line 6 and the timer reset line 7. The timer output line 8 connected to the timer unit 5 is connected to the decoder unit 4. The timer section 5 outputs a time lapse signal to the timer output line 8 when the counted time exceeds a preset time.

FIG. 2 shows an example of a housing case that houses a wireless selective receiver and acts as a transmitter. The receiver accommodating section 201 is a part for accommodating the wireless selective receiver when the wireless selective receiver is not used. An active button 202 and a call button 203 are provided corresponding to each receiver housing. When renting the wireless selective receiver, the active button 202 is pressed, and when calling the wireless selective receiver, the corresponding call button 203 is pressed.

The operation of this embodiment will be described below.

FIG. 3 is a time chart showing the operation of the embodiment of the present invention. Active switch 202 in receiver storage case
When is not pressed, the signal train consisting of the sync signal 101, the disable signal 102 and the idle signal 103,
It is sent out at regular time intervals. The wireless selective receiver synchronizes the signal with the synchronization signal 101 and detects the disable signal 102. When the disable signal 102 is detected, the signal 106 flowing through the timer control line 6 becomes "0", and in this state, the timer section 5 does not operate. The wireless selective receiver is rented out here, and the active button 202
When is pressed, the part to which the disable signal 102 has been sent until now is replaced with the start signal 104 as the reference signal. When the decoder section 4 receives the start signal 104, it sets the signal 106 flowing through the timer control line 6 to "1". This causes the timer unit 5 to start operating. When the decoder unit 4 receives the start signal 104 again, the decoder unit 4 outputs the reset signal 107 to the timer reset line 7. When receiving the reset signal 107, the timer unit 5 is reset and restarts its operation from the beginning. As a result of the timer section 5 being repeatedly reset by the start signal 104, the time elapsed signal 108 flowing through the timer output line 8 remains "0".

When the call button 203 is pressed, instead of the idle signal 103, the call signal 105 for calling the corresponding radio selective receiver
Is sent. When the decoder unit 4 receives the ringing signal 105, it drives the ringing tone generation circuit 9 to output the intermittent ringing tone 109 from the speaker 10. This allows the carrier to know that there is a call.

Next, the operation when the carrier goes out of the service zone will be described with reference to FIG. When the carrier goes out of the service zone, the start signal 104 is not received. Therefore, the reset signal 107 is sent from the decoder unit 4 to the timer unit 5.
Is not output, the timer unit 5 continues to operate without being reset, and when a certain time has elapsed, the time elapsed signal 108 indicating that the timer setting time has passed becomes “1”. The decoder unit 4 receives the signal and drives the ringing tone generating circuit 9, thereby causing the speaker 10 to output a continuous alarm tone 109. This can give a warning when the carrier leaves the service zone that he has a radio selective receiver. The lender can also know that the wireless selective receiver has left the service zone.

In the embodiment described above, the ringing tone is an intermittent tone, and the alert tone is a continuous tone. However, instead of the alert tone, a synthesized voice such as "Please return the caller to the staff when you go out" is output. It is also possible to do so. Also,
The example in which the start signal is intermittently transmitted has been described, but a continuous start signal may be transmitted.

〔The invention's effect〕

As described above, in the paging service of the small service zone, the present invention can know that the lender has left the service zone and can know that the receiver has forgotten to return by the occurrence of a predetermined alarm sound. It has the effect of being able to.
