DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a pager according to the present invention as a whole, and reference numeral 11 is its receiving circuit. Although not shown, the receiving circuit 11 is configured in a super-heterodyne system and has an antenna input circuit to an FSK demodulation circuit. When the pager signal is transmitted from the operator, the signal is received by the receiving circuit 11, the demodulated signal is supplied from the receiving circuit 11 to the decoder circuit 12, and the identification code and various data are extracted from the decoding circuit 12. .

Then, the extracted identification code and data are supplied to the microcomputer 20.
That is, the microcomputer 20 has a CPU 21 for executing programs, a ROM 22 in which various programs are written, and a RAM 23 for work area and data area.
3 is connected to the CPU 21 through the bus line 29.

In the ROM 23, for example, a message table MSGT as shown in FIG. 3, that is, a correspondence table MSGT between the character string data of the message content and the message number thereof.
Is also prepared. The ROM 23 is also provided with an identification code for identifying this pager.

Further, an interface circuit 24 is connected to the bus 29, and when the decoder circuit 12 outputs the identification code and the data, the identification code and the data are taken into the microcomputer 20 through the interface circuit 24. A drive circuit 26 is connected to the bus 29 through the port 25.

In the drive circuit 26, a sounder (acoustic unit) 31 such as a speaker or a piezoelectric element for acoustically notifying the wearer that the pager has been called, and a vibration for notifying the wearer. Is connected to the vibrator 32 for.

A display controller 27 is connected to the bus 29, and an LCD 33 is connected to the display controller 27 as a display element for displaying a message or the like.

Further, various operation keys K1 to KN are connected to the bus 29 through the key interface circuit 28. In this case, the key K1 is composed of, for example, a slide switch, and the keys K2 to KN are composed of non-lock type push switches.

Further, the pager is provided with an audio output circuit 40. The voice output circuit 40 is for converting the message number sent from the caller into voice and outputting the voice, and therefore has the memory 41 to the speaker 45.

The memory 41 has, for example, a voice table SNDT as shown in FIG. 2, that is, a correspondence table SNDT of digital voice data for transmitting a message by voice and its message number. Also, in this example, the correspondence between the message numbers and voice data in the voice table SNDT is as follows:
It is made equal to the message number of the message table MSGT and the correspondence with the message.

Further, the memory controller 42 is connected to the memory 41, and the memory controller 42 is connected to the bus 29. This memory controller 42
Is for reading digital audio data from the memory 41 according to an instruction from the CPU 21.

When the message number data is supplied from the CPU 21 to the memory controller 42, the memory 41
The digital voice data of the message corresponding to the message number is read from. Then, the read digital audio data is supplied to the D / A converter 43 and D / A converted into an analog audio signal, and the analog audio signal is supplied to the speaker 45 through the amplifier 44.

In such a structure, when the caller sends a message, the same key operation as in a general pager is performed. That is, for example, call the number given to the pager. Code "* 4 * 4" indicating that the message was sent
With the dial keys. Message is "TEL Seyo" of message table MSGT
, The message number is “02”, so “0
Enter "2" using the dial keys. Enter "#" indicating the end using the dial keys.
Key operation.

Then, from the base station, the identification code for identifying the pager of the item and the message number "0" input in the item
2 "is converted into an FSK signal and transmitted.

Then, the pager of the carrier carries the FSK
When the signal is received, the decoder circuit 12 outputs the identification code and the data indicating the message number. In the microcomputer 20, the identification code from the decoder circuit 12 is compared with its own identification code written in the ROM 22. .

When the two match, that is,
When sending to you, the key K1 is checked,
When this is set to the first mode, the drive circuit 26 drives the sounder 31 to output the ringing sound, and the ringing sound is notified by sound. Further, when the key K1 is set to the second mode, the drive circuit 26 causes the vibrator 3
2 is driven, and the fact that there is a call is notified by vibration.

Further, in the microcomputer 20, the message number data "02" sent together is
Message table stored in RAM23
Display data "TEL SEIYO" by referring to MSGT
And the display data is supplied to the display controller 27. Therefore, the LCD 33 displays the character string of "TEL seyo" selected by the caller.

It should be noted that the RAM 23 stores, for example, the latest 10 messages of the message number data transmitted from the operator.
Individual data is stored, and the previous data is erased. In addition,
Of the latest 10 data, the newest data is number 1 and the oldest data is number 10.

Further, when the message number data is stored in the RAM 23 as described above, when the reproduction key of the keys K1 to KN is pressed, the latest message number data is stored in the RAM 23.
From the memory controller 42
And the corresponding digital audio data is retrieved from the memory 41.

In the present case, the latest message number is "02", which is read from the RAM 23 and supplied to the memory controller 42. Therefore, from the memory 41, "Call me" of the voice table SNDT is displayed. Digital audio data is retrieved. Then, since this digital voice data is supplied to the D / A converter 43 through the memory controller 42, the voice of "please call" is output from the speaker 45.

Therefore, when the caller makes a call, by pressing the reproduction key of the keys K1 to KN, the message can be heard by voice. Or even after some time has passed since the call was made,
If you do not perform the key operation described below, you can hear the message when the call was made.

The latest version stored in the RAM 23
A memory pointer PNTR for designating one of the 10 message numbers is prepared, and each time the memory key of keys K1 to KN is pressed, the memory pointer PNTR changes. The data is changed cyclically in the past one by one.

At this time, the number indicating which data is designated by the memory pointer PNTR, that is, the number of the data designated by the pointer PNTR among the numbers given to the 10 data is the LCD 33. Is displayed in.

Then, when the reproduction key of the keys K1 to KN is pressed within, for example, 5 seconds after the target data number is displayed, the message number designated by the memory pointer PNTR at this time is displayed. The data is taken out from the RAM 23 and supplied to the memory 42. Therefore, the voice of the message having the message number designated by the memory pointer PNTR at this time is output from the speaker 45.

Further, when the clear key of the keys K1 to KN is pressed, all the message numbers stored in the RAM 23 are erased.

Thus, according to this pager, when a call key is pressed when the reproduction key of the keys K1 to KN is pressed, a message from the caller is output by voice, so that the message can be easily understood by a person. Can be told.

In the above description, an earphone may be used instead of the speaker 45.

[0037]

According to the present invention, since the message from the caller is output by voice, it is possible to convey the message in an expression that is easy for a person to understand.
