Field of the Invention The present invention relates to a radio selective calling receiver, and more particularly to a radio selective calling receiver capable of temporarily storing and reproducing not only a ringing tone but also received numbers, voice information and the like. ..

[0002]

2. Description of the Related Art With the widespread use of radio selective call receivers, their service contents are required to be highly functional and diversified. Examples of service contents currently performed include calling, transmission of numbers and character information. Transmission of even shorter voice information is about to be performed.
In Japanese Patent No. 60227, voice data input via a telephone network is A / D converted, the digital data is wirelessly transmitted, and the digital data received by a wireless selective call receiver is converted into analog data by a D / A converter. It is described that the technology returns to the above and outputs as voice from a speaker.

[0003]

In a radio selective calling receiver capable of storing voice information in addition to numerical and character information, reproduction of numerical information and voice information is usually performed by the operation of the radio selective calling receiver carrier. Then, display it on the display device or make it an audio signal. In that case, if the mixed information of the numerical message and the voice message, or either single information is transmitted, the called party does not know the entire stored information, so the callee reads the numerical message on the display and the voice information is displayed on the speaker. You need to do all the listening. Further, although the numerical message is self-explanatory, since the voice message cannot know the existence of the information unless it is reproduced, the called party always has to perform a reproduction operation. In addition, there is a problem in that the end of the voice information is not known even when the voice is reproduced, and there is a feeling of frustration as to how long the voice information will continue. Furthermore, the radio selective call receiver is required to have low power consumption in order to reduce the frequency of battery replacement.

It is an object of the present invention to provide a radio selective call receiver that allows the called party to quickly recognize the type of stored information received. Another object of the present invention is to provide a radio selective calling receiver that allows a called party to quickly grasp the amount of received voice information. Still another object of the present invention is to provide a radio selective calling receiver which can prevent useless reproduction operation and consume less power.

[0005]

To achieve the above object, the present invention provides a radio selective calling receiver having at least means for receiving and storing voice information, and means for checking the amount of voice information, and And a display means for displaying the amount of seed voice information. The means for checking the information amount of the voice information includes the case of only the presence or absence of voice, and the case of obtaining the information amount of the voice information stored in the storage means. The display means is
Although not particularly limited, the presence / absence of the information amount of the audio information and the amount thereof are displayed in a display form that can be easily identified by symbols, colors, and graphs.

Furthermore, when other information such as character information, numerical information, symbol information, etc. is added to the transmission information in addition to the voice information, a means for identifying the type of the received information is added to the display means, and The type of the received information is displayed on the display means. Although the display form is arbitrary, it is preferable that the information of the type of the received information is displayed in characters, colors, or symbols so that the information can be instantly identified.

Further, in the reproducing section of the receiving device, a driving means for the carrier to select and reproduce based on the display result of the information amount of the audio information and the type of the received information, that is, a selection switch and a reproduction switch. To provide. A dedicated device may be provided for the means for checking the information amount of the audio information, the means for identifying the type of the received information, and the means for driving the display means, but a microprocessor that also serves as a demodulation operation of the receiver Configured as a (microcomputer) function.

[0008]

By displaying a character or a symbol indicating that the voice information is stored in the storage means on the display, the called party who is the receiver's carrier can hear the voice information included in the incoming message. Since it is possible to determine whether or not there is, it is possible to prevent useless reproduction operation for listening to audio information. Further, since the called party can grasp the information amount of the stored voice information, the annoyance of not knowing the end of the voice information can be eliminated, and the time to move to the next action can be predicted, so that waste of time can be saved. .. In addition, since the reproducing circuit does not operate even if the reproducing operation is mistakenly performed when there is no audio information, the wasteful current consumption of the circuit is suppressed, the internal battery can be saved, and the actual battery life can be lengthened. it can.
