Abstract

PURPOSE:To simply and surely retrieves messages by displaying an initially inputted message in the case of successively displaying plural messages, and displaying a leading message in the case of divided display. CONSTITUTION:A selective call signal from a base station which is not shown is received by a radio circuit 2 through an antenna 1 and sent to a demodulator 3 to demodulate the signal and the demodulated signal is applied to a control circuit 40. The circuit 40 reads out the identification (ID) information of its own receiver which has been previously stored in an ID ROM 5 connected to the circuit 40 and reads out ID information included in the call signal by an information extracting means 41 built in the circuit 40 to compare both the ID informations. When the contents of both the informations match with each other, the circuit 40 decides the existence of a call signal to its own receiver and sends a call informing signal to a driving circuit 6 to generate a call tone from a speaker 7. Since it is unknown whether plural kinds of messages are included or not or a long message is dividedly displayed or not, a message number code is added to each message by the means 41 to prevent the generation of an error in message retrieval.

[Purpose of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiver.

0002

BACKGROUND OF THE INVENTION In recent years, selective calling receivers have become known which, in addition to generating a ring tone in response to a selective call, are equipped with a display and have the function of displaying a received message on the display. It is being A selective call receiver having such a display function is shown in FIG. In this selective call receiver, a selective call signal sent from a base station (not shown) is transmitted to the antenna 1.
is received by the wireless circuit 2 via. This selective call signal is further sent to demodulation circuit 3, demodulated, and given to control circuit 4. The control circuit 4 includes an attached ID-ROM 5.
The ID (identification information) of the own device stored in advance is read out and compared with the ID included in the selective call signal. As a result of the comparison, if the two IDs match, the control circuit 4 sends a call notification signal to the drive circuit 6 indicating that there is a call to the own device. As a result, a ringing tone signal is applied from the drive circuit 6 to the speaker 7, and the speaker 7 generates a ringing tone. Thus, the holder of the selective call receiver knows that a call has been made.

[0003] The selective call signal can include a message code. If the selective call signal includes a message code, the control circuit 4 performs error correction and decoding of the message code, and sends the decoded message code to the display drive circuit 8. Display drive circuit 8
generates display pattern data corresponding to the message code, and drives the LCD 9 based on this to display the message. In addition, the message code is M-RAM10
It is stored in , and is used to restart the message display, as well as to display the following.

[0004] If the number of digits (number of characters) of a message exceeds the number of digits that can be displayed on the LCD 9, the message cannot be displayed on the LCD 9 at once. Therefore, in response to the operation of the display switch 11, the control circuit 4 reads message codes corresponding to the remaining messages from the M-RAM 10, and supplies them to the display drive circuit 8 for display. If it cannot be displayed twice, furthermore,
The same process as above is performed for the remaining message codes. Also, the selective call receiver can store multiple messages. In this case as well, by operating the display switch 11, messages can be displayed one after another in the same way as above, and each message can be displayed for a long time.
If all the messages cannot be displayed on D9, the remaining messages can be divided and displayed by operating the display switch 11 as described above. And several times the display switch 11
The operation returns to the initial display.

[0005]

[Problem to be Solved by the Invention] However, according to the above-mentioned conventional selective call receiver, the messages A, B,
In the case where an extremely large number of C,...,Z are sent,
For example, if you try to display message A while displaying message F, repeat the operation of display switch 11 to display messages G, H, I, J, ..., Z, and then press display switch 11 again. There was a problem in that it was cumbersome to operate.

[0006]Also, even if the number of messages itself is not large, the length of one message is long, and at one time the LCD
For example, if message C cannot be displayed in C
1, C2,..., Cn and are displayed separately. In such a case, the message C3 related to the division
To return to the first message C1 when displaying the first message C1, repeat the operation of the display switch 11 to display the divided messages C4, C5, C6..., Cn, as well as D, E, F,..., Z, It is necessary to display A and B and then operate the display switch 11 again, which again poses a troublesome problem.

The present invention has been made to solve the problems of the conventional selective call receiver, and its purpose is to easily return to the beginning of the message and the beginning of the message. It is an object of the present invention to provide a selective call receiver whose operation can be simplified. [Structure of the invention]

[0008]

[Means for Solving the Problems] The present invention includes information extraction means for receiving a selective call signal and extracting destination identification information and a message code from the signal, and destination identification information extracted by the information extraction means. An identification information match detection means for detecting whether the identification information matches the identification information of the own machine; an input means used for inputting data; a display means for displaying a message; and the identification information match detection means detects whether the identification information matches. displaying a message based on the message code extracted by the information extraction means on the display means, and continuously displaying the message in sequence when a first input is made from the input means. The selective call receiver is provided with display control means for displaying the first message among the messages when a second input is made from the input means.

[0009] In another aspect of the present invention, information extraction means receives a selective call signal and extracts destination identification information and a message code from the signal; identification information matching detection means for detecting whether the identification information matches the identification information; input means used for data input; display means for displaying a message; is detected, a message based on the message code extracted by the information extraction means is displayed on the display means, and when a first input is made from the input means, the messages are displayed in sequence in a continuous manner. On the other hand, when a second input is made from the input means, the selective call receiver is provided with display control means for displaying the first message when one message is divided and displayed.

0010

According to the configuration of the present invention, no matter what kind of message is being displayed, the first message is displayed only by a predetermined input from the input means, making it possible to search for messages easily.

Furthermore, in another aspect of the present invention, a third
When this input is made, the display returns to the beginning of the display related to the division, and the message can be easily searched.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a selective call receiver according to an embodiment of the present invention.
Shown below. In this selective call receiver, a selective call signal sent from a base station (not shown) is received by a radio circuit 2 via an antenna 1. This selective call signal is further sent to the demodulation circuit 3, demodulated, and given to the control circuit 40. The control circuit 40 reads out the ID (identification information) of the own device stored in advance in the attached ID-ROM 5, extracts the ID included in the selective call signal as an information extraction means 41, and compares it with this. do. As a result of the comparison, if the two IDs match, the control circuit 40 sends a call notification signal to the drive circuit 6 indicating that there is a call to the own device. As a result, a ringing tone signal is applied from the drive circuit 6 to the speaker 7, and the speaker 7 generates a ringing tone. Thus, the holder of the selective call receiver knows that a call has been made. In this way, the control circuit 4
0 works as identification information matching detection means 42.

[0013] The selective call signal may include a message code. When the selective call signal includes a message code, the control circuit 40 functions as an information extraction means 41, performs error correction and decoding of the message code, and displays the decoded message code in the display drive circuit 8. Send to. In this way, the control circuit 40 functions as the display control means 43. The display drive circuit 8 generates display pattern data corresponding to the message code, and based on this, drives the LCD 9 to display the message. Note that the message code is stored in the M-RAM 10,
In addition to being used to restart message display, it is also used to display the following.

[0014] If the number of digits (number of characters) of the message exceeds the number of digits that can be displayed on the LCD 9, the message cannot be displayed on the LCD 9 at once. Therefore, in response to the operation of the display switch 11, the control circuit 40 reads message codes corresponding to the remaining messages from the M-RAM 10, and supplies them to the display drive circuit 8 for display. If it cannot be displayed twice, furthermore,
The same process as above is performed for the remaining message codes. Further, the selective call signal can include a plurality of messages. In this case as well, by operating the display switch 11, messages can be displayed one after another in the same way as above, and each message can be displayed for a long time on the LCD.
9, the remaining messages can be displayed by operating the display switch 11 as described above. Then, by operating the display switch several times, the display returns to the initial display.

Furthermore, in the selective calling receiver according to the embodiment described above, it is unclear whether the message contains multiple types or the message is long and is displayed in parts. , display control means 41
sends a message number code in order to display the message number in addition to the message. As a result, for example, when messages A, B, and C of different types are sent, message numbers "1", "2", and "3" are added to these messages and displayed. Therefore, if the above message A is long and becomes A1, A2, A3,
The same message number "1" is added to the messages A1, A2, and A3 that are displayed separately and displayed.

FIG. 2 shows an example of message display. Here, the LCD 9 has the capacity to display up to 12 digits, so when a message consisting of 19 digits arrives, the same message number "1" is displayed as shown in FIGS. 2(a) and 2(b). "123456" is added at the top.
789012" and "3456789" for display. Also, a message different from the above “45
6-7890", this message will have a message number "2" added to the top and a "4
56-7890'' is displayed as shown in FIG. 2(c).

The displays shown in FIGS. 2(a), 2(b), and 2(c) are sequentially switched by operating the display switch 11.
In this embodiment, in addition to the above, the display control means 43 operates according to the flowchart of FIG. That is, the selective call receiver according to this embodiment has a volume switch 12 as shown in FIG.
and a cue switch 13 for split display. For example, the volume switch 12 is a switch that is input so that the volume of the ringer will gradually increase or decrease if it is continuously operated (pressed down) during initialization such as when the power is turned on. Repurpose as. When the above-mentioned initialization is completed and a selective call signal arrives to initiate a display operation, the display control means 43 causes the first message to be displayed (301). Then, the operation of the display switch 11 is monitored (302), and when the display switch 11 is operated, control is performed to display the next message (including the case of division) (303). Further, the operation of the volume switch 12 is monitored (304), and when the volume switch 12 is operated, the process returns to step 301 to control the display of the first message. Furthermore, the operation of the cue switch 13 is monitored (305), and when the switch 13 is operated, it is detected whether split display is being performed (306), and only when split display is being performed, the split display is performed. The first message related to the display is displayed (307) and the process returns to step 301.

Although three switches were used in this embodiment, one or two switches are used, and the number of times the switch is operated within a predetermined period of time (for example, 3 seconds) is detected. If the screen is displayed twice, the first message may be displayed, and if split display is performed, the first message may be displayed when the screen is displayed three times.

[0019]

[Effects of the Invention] As explained above, according to the present invention, the first message is displayed when a predetermined input is made, or the first message in the case of split display is displayed, making message searching easier than before. can be done.
