Then, the message information stored with the classification name in the RAM 9 is displayed on the LCD 12 for each classification selected by the key operation of the key input unit 10.

The process of classifying / storing the message information at the time of reception and the process of searching / displaying the message information after the reception will be sequentially described below with reference to flowcharts.

First, the classification / storage process at the time of receiving message information will be described with reference to the flowchart shown in FIG.

When there is an incoming call, the pager 1 checks whether the received message information includes sender name information (step R1). Here, if the information in the message block shown in FIG.
Since the sender name information is included, the sender name in FIG.
It is stored in the area for storing the sender name of the memory block shown in (B) (step R2). This memory block corresponds to one message memory area of the memory areas formed in the RAM 9 shown in FIG.

Next, it is checked whether or not the received message information includes a message (step R
3).

When the received message information does not include the sender name information in step R1, the process directly proceeds to step R3 to check whether or not the message message information is included.

Here, if the message information shown in FIG. 5A is received, since the message message information is included, the classification of the message is judged from the content of the message message information (step R4).

The judgment of the classification of the message is made based on the ending of the message information.

That is, the ending of the message message information is extracted, and it is determined whether the extracted ending corresponds to which of the classification term endings stored in the ROM 8.

For example, as shown in FIG. 6 (A), when the message message information is "please go straight to the head office at 9:00 tomorrow", the ending of the message information is "please". As can be seen from the correspondence table shown in FIG. 2, the message classification is determined to be “command”, and FIG.
As shown in, when the message information is "Today's dinner will change at 6:30", the ending of the message information is "do", so the message classification is judged as "memo". . Further, as shown in FIG. 6C, when the message message information is "Are you sure to meet today at 6:00?", The ending of the message information is "tai?" Q. "

When the judgment of the message classification is completed, the judged classification name is RA shown in FIGS. 3 and 5B.
In addition to storing the classification name of the memory block of M9, the message message information is stored in the area of the RAM9 storing the message message (step R5).

Next, the arrival time is acquired, and the acquired arrival time is stored in the memory block area for storing the arrival time (step R6).

When the classification of the message information and the storage of the necessary data in the RAM 9 are completed in this way, the alerting section 6 is driven to perform a call-in operation for notifying that the call has arrived (step R7), and the processing is performed. To finish.

In step R3, when the received message information does not include the message information,
The process proceeds to step R6, the arrival time is acquired, and the RAM 9
It is stored in the area for storing the incoming time of the memory block (step R6), and the incoming operation is performed (step R7).

As described above, when the pager 1 receives the message information, the pager 1 classifies the message information according to the contents of the received message information and gives the classification name,
It is stored in the RAM 9 together with the classification name to which the message information is added.

Next, the message information retrieval / display processing will be described with reference to the flowchart shown in FIG.

When the memory key of the key input unit 10 is turned on, the pager 1 shifts to the display mode, and includes a reception order display mode, a sender display mode and a classification display mode.

When the incoming order display mode is selected as the display mode in step T1, the incoming time of the RAM 9 is searched, the message information of the latest incoming time is read, and L
It is displayed on the CD 12 (step T2).

When the display mode for each sender is selected as the display mode in step T1, the sender names are sequentially read from the RAM 9, the sender list is displayed on the LCD 12, and the key operation of the key input unit 10 is performed. Wait for the sender to be selected (step T3).

When the sender is selected, the message information of the latest arrival time of the messages corresponding to the selected sender is read from the RAM 9 and displayed on the LCD 12 (step T4).

Further, when the classified display mode is selected as the display mode in step T1, the sender's incoming call order format and a classified display format list showing the incoming call order format are displayed,
Check which is selected (step T
5).

When the incoming order format is selected in step T5, the classification list of "command", "memo", "question", etc. is displayed on the LCD 12 and the selection of the display classification is waited for (step S5). T6), when the classification is selected, the message information of the latest arrival time is read from the RAM 9 among the message information corresponding to the selected classification, and L
It is displayed on the CD 12 (step T7).

In step T5, when the sender's incoming call order format is selected, the classification list is displayed on the LCD 12 as in step T6, and the display classification is waited for (step T8). ), When the classification is selected, the sender list is further displayed, and the sender is waited for selection (step T9). When the sender is selected, the latest message information among the message information of the selected sender that corresponds to the selected category is read from the RAM 9 and displayed on the LCD 12 (step T10).

In this way, according to the selected display mode, the latest message information among the message information corresponding to that display mode is read from the RAM 9,
When it is displayed on the LCD 12, it is then checked whether or not there is a key input (step T11), and if there is a key input, the type of the input key is checked (step T).
12).

In step T12, when the input key is the memory key, the message information next to the message information being displayed is read from the RAM 9 and the LCD 12
Is displayed (step T13), and the process returns to step T11 to check whether or not there is a key input.

If the input key is the page key in step T12, the message information of the next page is read from the RAM 9 and displayed on the LCD 12 (step T1).
4) Return to step T11 to check whether there is a key input.

When the key input is performed in step T11 and the key input in step T12 is the end key, it is determined that the end of the display mode is instructed, and the display mode processing is ended.

As described above, when the message information is received, the message is classified based on the content of the message information, the classification name and the arrival time are added to the message information, and stored in the RAM 9. Then, when the display mode is selected, the message information is selected and displayed on the LCD 12 based on the classification name added to the sender name message information included in the message information and the arrival time. As a result, by appropriately selecting the type of display mode,
The necessary message information is quickly searched and the LCD 12
The pager 1 can be displayed, and the usability of the pager 1 can be improved.

In the above embodiment, the classification name corresponding to the contents is added to the message information and stored in the RAM 9, but the present invention is not limited to this, and, for example, a classification code corresponding to the classification name is given. R is added to the message information
It may be stored in AM9.

Since the classification code corresponding to the classification name is added to the message information and stored in the RAM 9, the RAM 9 can be searched at high speed and the storage capacity can be effectively used. .

In the above embodiment, the message information is classified based on the ending of the message information. However, the present invention is not limited to this, and the message information is transmitted as a message code designating a fixed phrase. When the message comes, the message information may be classified based on this message code.

Further, in the above embodiment, the RAM 9
The message is stored without being divided into areas for each message classification. However, even if the RAM 9 is divided into areas according to the message information classification and each message is sorted and stored in the area of the RAM 9 corresponding to the classification. Good. In this case, since it is not necessary to give a classification name corresponding to the content to the message information, the message information can be easily searched for each classification at high speed, and the storage capacity can be effectively used.
