Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a radio selective calling receiver.

A wireless selective calling receiver is a device known as a pager that receives a predetermined radio signal at a specified timing, and when the radio signal contains its own call code, It is a portable radio receiver that detects and generates a ring tone.
A telephone subscriber accesses the transmitting station of this radio wave signal via the telephone network, and by performing predetermined operations can broadcast a desired call code from the transmitting station.

[Prior Art] A conventional radio selective calling receiver is designed to generate a ringing tone by applying a trigger input to a ringing tone generating means as soon as its own calling code is detected in a received radio wave signal.

[Problem that the invention attempts to solve]

However, it is undesirable for the user of the wireless selective calling receiver to receive a ringing tone when the user is attending a ceremony or having an important meeting.
For this purpose, a method can be considered in which only the ringer generation means is disconnected by a switch operation, and the call is displayed optically. You cannot confirm that a call has been received unless you take out the receiver and check it.

The present invention improves on this by providing a wireless selective calling receiver that prohibits the transmission of the ringing tone when the user does not wish to do so, and automatically transmits the ringing tone when the time comes for the ringing tone to be transmitted. The purpose is to provide.

[Means for solving problems]

The present invention is characterized in that a timer means is provided for prohibiting a trigger input from being applied to the ringing tone generating means until a set time has elapsed. This timer means can be operated externally by the user to arbitrarily set and start the set time.

[Effect]

Users of wireless selective calling receivers must use wireless selective calling receivers during periods when they do not want a ring tone to be transmitted, such as when attending a ceremony, having an important meeting, or participating in a concert. Set a timer on the machine and start it in advance. Even if there is a call during the operating period of this timer, the transmission of the ringing tone is prohibited until the time set in this timer has elapsed. When this set time has elapsed, a ring tone is automatically sent out.

〔Example〕

FIG. 1 is a block diagram of a device according to a first embodiment of the present invention. The receiving circuit 11 receives a predetermined radio signal arriving at the antenna 12 at a designated timing, and detects whether or not the radio signal includes its own call code. When its own call code is detected, a detection output is sent to the signal line 13. This detection output is input to the timer circuit 15. The output of this timer circuit 15 is input to the ringing tone generation circuit 17,
The output current of the ringing tone generating circuit 17 is
The signal is transmitted as an amplified sound signal from 8. The timer circuit 15 has a display circuit 20 that displays the remaining time.
is connected thereto, and an operation switch 21 is provided for the user to operate the timer circuit 15 from the outside to set the set time of the timer circuit 15.

FIG. 2 is a perspective view of the apparatus of the first embodiment.
On the surface of the device, an operation switch 21, a speaker 18,
Display circuit 20 and reset power speaker 23
Equipped with

When the user of this device does not want a ring tone to be sent out, such as when attending a ceremony, having an important meeting, or participating in a concert, the user must receive a wireless selective call before Operate the operation switch 21 of the machine to set and start the timer. Even if there is a call during the operating period of this timer, the transmission of the ringing tone is prohibited until the time set in this timer has elapsed. When this set time has elapsed, a ringing tone is automatically sent out from the speaker 18 without any operation.

FIG. 3 is a block diagram of an apparatus according to a second embodiment of the present invention. This embodiment is a radio selective call receiver which has a built-in clock circuit in addition to timer means and has further advanced functions.

That is, in FIG. 3, the device of this embodiment includes a clock circuit 28 in addition to the structure of the device of the first embodiment.
This clock circuit 28 is a known digital clock that measures the time (am/pm or 24-hour system), and the time measurement contents of this clock circuit 28 and the remaining time contents of the timer are switched by a switching circuit 25 and displayed on the display circuit 25. This is the configuration to display. This switching circuit 25 is operated by a user using an operation switch 27. Further, in conjunction with the operation of this switching circuit 25, the operation switch 21 for setting the timer is operated by the switching circuit 24.
The device is connected to a timer and a clock so that the time or time can be set on either the timer or the clock.

In the device shown in FIG. 3, the operation of the timer circuit 15 is similar to that explained in the first embodiment, and even if the detection output is sent to the receiving circuit 11,
This is prohibited from being input to the ringing tone generation circuit 17 until the set time of 5 has elapsed.

In addition, in FIG. 3, an operation switch 26 is connected to the input circuit of the timer circuit 15, and by operating it to close it, even if there is no output from the receiving circuit 11, the set time of the timer circuit 15 has elapsed. The ringer generating circuit is activated. This makes it possible to test the timer and ring tone, and also allows it to be used as a timer regardless of radio selective calling.

By implementing the clock circuit 28 in this manner, the display circuit 20 can be used to display the time when there is no wireless selective call. In addition, when there is a wireless selective call and the own call code is detected, the time will be displayed in a blinking manner, so that even if the timer is running and the ringtone is not yet sent out, the time and date of the call will be displayed. can be known.

FIG. 4 is a perspective view of an apparatus according to a second embodiment of the present invention. There are three operation switches 21, 26 and 27, and the display circuit 20 has a large area because it displays the time. The power switch 23 also serves as a reset switch.

[Effect of idea]

As explained above, according to the present invention, in situations where it is not desirable for the ringer to sound, such as when attending a ceremony, having an important meeting, or participating in a concert, the ringer can be sent. When the time set by the timer has elapsed, a ringtone is automatically sent out, which has the effect of making it possible to know without a doubt that a call has been made during the prohibition period.
