Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a selective calling device, and an object thereof is to be able to display a telephone number to be contacted.

With conventional receivers equipped with selective calling devices (so-called pagers), when the receiver receives a call, it calls one or two types of calls.
Because the call was announced by making various noises, only predetermined contacts could be contacted.

According to the present invention, a display device is provided on the receiver to display a telephone number to be contacted, so that the person carrying the telephone number is informed of the telephone number to be contacted. An embodiment of the present invention will be described below with reference to FIG.

1 is an FM receiver, 2 is a demodulator that demodulates the FM signal, 3 is a selective call number storage circuit that stores the selective call number of the receiver, and 4 is a decoder section, in which the received signal is stored in the storage circuit 3. A function to determine whether the calling number is one's own,
It also has a function to decipher the phone number to call back.

Reference numeral 5 denotes a q-bird sound driving circuit for driving a sounding body 6 that emits a chirp sound to notify a call, 7 a memory circuit for storing the telephone number to be called back decoded by the decoder 4, and 8 a memory circuit for displaying the telephone number. A drive circuit, 9 a display such as a display tube for displaying the number, an oscillation circuit that emits a dial tone corresponding to a telephone number, and 11 an oscillation start switch. Next, the operation of this device will be explained.

When the selective calling device shown in FIG. 1 receives a calling signal consisting of a selective calling signal A and telephone number information B as shown in FIG. 2, this signal passes through an FM receiver 1 and is demodulated by a demodulator 2. Ru.

If the received selective calling signal matches the own calling number stored in the selective calling number storage circuit 3, the decoder section 4 drives the sounding body 6 to notify the caller of the call. Next, the decoder section 4 decodes the telephone number to be called back from the telephone number information B that follows the selective call signal A, temporarily stores this number in the telephone number storage circuit 7, and displays the number on the display 9. indicate. The person carrying the receiver is informed of the call by the Q-tone of the sounding body 6, and can confirm the telephone number to be called back from the number displayed on the display tube 9. Next, when the carrier picks up the handset of the telephone for the purpose of calling back and presses the oscillation start switch 11 near the telephone, the dial tone oscillation circuit 10 is activated and the number stored in the telephone number storage circuit 7 is activated. By generating a corresponding dial tone and inducing it in the telephone set, the carrier can call the intended party by telephone without having to turn a dial. As described above, according to the present invention, in addition to a simple calling function, the carrying person can immediately know who to contact, and the function can be expanded to a large number of people.

Furthermore, since a dial tone oscillator is added, the desired dial can be automatically made, and the caller can be answered quickly.

Claims (1)

[Claims] 1. A demodulator that demodulates a modulated signal modulated by information of a selective call number and a telephone number, a selective call number storage circuit that stores its own selective call number, and a received call number that is stored in the storage circuit. a decoder that determines whether the number is a registered number and decodes the telephone number information; a telephone number storage circuit that stores the telephone number decoded by the decoder; and a display that displays the contents of the telephone number storage circuit. and dial tone generating means for generating a dial tone of a number stored in the telephone number storage circuit in the telephone via a dial tone oscillation circuit.
