Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a selective call receiver and a mobile radio having a message display function.

(Prior Art) In recent years, as a new type of selective calling method, a method has been proposed in which a call can be made by sounding or emitting light and a message can be transmitted and displayed. This type of scheme is used, for example, when a base station is sent a paging request and transmission message for any selective paging receiver.
A base station creates a selective call signal including an individual number code of the selective call receiver and a message code obtained by encoding the transmission message, and transmits the selective call signal to an available call of a group to which the selective call receiver belongs. It is inserted into a word and sent. The selective call receiver receives the selective call signal, compares the individual number code with the individual number code of its own device, and when both codes match, indicates to the subscriber that ringing or light emission has generated a call. In addition, the message code is decoded and displayed on a liquid crystal display, for example. Using such a method is very convenient because, for example, the telephone number of the contact and the name of the caller can be transmitted to the subscriber as a message.

By the way, the selective call receiver to which such a method is applied generally has an auto reset function of automatically deleting the message display when a message display time reaches a predetermined time when a call occurs. . For this reason, there is no problem that the message is left as it is displayed, so that unnecessary consumption of the battery can be prevented.

However, this type of receiver, due to the auto reset function, even if the subscriber is still checking the message, the display will unconditionally disappear if the display time elapses,
For example, if the message is long, the message cannot be confirmed within the display period at the time of the call occurrence, making it difficult to confirm. Further, once the display disappears, the message display switch must be operated to display the message again, so that the operation is extremely troublesome. Furthermore, it is difficult for an unskilled subscriber or the like to use the displayed message while checking the message.

(Problems to be Solved by the Invention) As described above, in the conventional selective call receiver, the message being displayed is unconditionally erased after a certain period of time irrespective of the subscriber's confirmation status by the automatic reset function. Therefore, it is difficult to confirm the message, the operability is poor, and there is a problem of giving a useless anxiety to the subscriber.The present invention pays attention to this point, and displays the message in any case. The purpose of the present invention is to provide a selective call receiver that enables continuous confirmation without erasing, thereby facilitating confirmation of a message, enhancing operability, and reducing a user's anxiety about use. is there.

[Configuration of the Invention] (Means for Solving the Problems) The selective call receiver and the mobile wireless device according to the present invention erase the display of the message when the display time of the message displayed on the display exceeds a predetermined time. In addition to the display erasing means, a means for displaying the remaining display time of the message during the display of the message is provided.

Further, the present invention further comprises display extension means, and when a predetermined display extension instruction is input during the display of the message, the display extension of the message is extended by the display extension means. I do.

(Operation) As a result, the subscriber can check the message from the remaining display time of the message displayed together with the message to determine whether or not to end the message, and if not, can extend the display time. Even if the message is long or the confirmation of the message cannot be started immediately after the start of the display, the message is not deleted once and the confirmation of the message can be continued as it is. Therefore, it is easy to confirm the message, whereby it is possible to always confirm the message accurately without error. In addition, since a cumbersome operation for displaying the once deleted message again is not required, the operability is improved. Further, the user's uneasiness of not knowing when the display of the message is to be deleted is also eliminated.

(Embodiment) FIG. 1 shows a configuration of a selective call receiver according to an embodiment of the present invention. The selective call receiver receives a selective call signal sent from a base station (not shown) by a radio circuit 2 via an antenna 1 and then mixes the signal with a local oscillation signal generated by an oscillation circuit 4 by a mixing circuit 3. The frequency is converted and then demodulated by the demodulation circuit 5. And
The demodulated selective calling signal is introduced into the control circuit 6, and the control circuit 6 compares the individual number code in the selective calling signal with its own individual number code stored in the storage circuit 7 in advance. When the codes match, a sound signal is supplied to the speaker 9 via the drive circuit 8 to generate a sound. At the same time, the message code inserted in the selective calling signal is decoded by the control circuit 6, and the decoded message is supplied to the display 10 for display. Reference numeral 11 denotes an operation input unit for inputting information such as stopping the display of a sound or a message, switching various modes, and selecting a display message.

By the way, the control circuit 6 has a function of checking the individual number code and decoding the message code,
Display erasure control means 61 and remaining display time display control means 62
And display extension control means 63. The display erasure control means 61 starts the timer 12 when the display of the message is started.
Is displayed, and when the time counted by the timer 12 becomes 0, the display of the message is deleted. The remaining display time display control means 62 causes the display 10 to display the time measured by the timer 12, that is, the remaining display time, in parallel with the display of the message during the display of the message. The display extension control means 63 resets the display time on the timer 12 when the timer switch of the operation input unit 11 is operated while the message is being displayed, thereby extending the message display time. .

With such a configuration, when a call to the own device is generated and the process shifts to message display control, the control circuit 6 first causes the display 10 to display a message in step 2a as shown in FIG. When the message is displayed, the control circuit 6 sets the display time of the message in the timer 12 in step 2b, and starts counting the display time.
In step 2c, the remaining display time measured by the timer 12 is displayed on the display 10 together with the message.

When the display of the message and the remaining display time is started, the control circuit 6 performs the operation monitoring of the display switch, the operation monitoring of the mode selection switch, the operation monitoring of the message selection switch, and the timer in steps 2d to 2h, respectively. The operation of the switch and the end of the display time are monitored. Then, when the display time set in the timer 12 becomes 0, the control circuit 6 erases the message currently displayed on the display 10 and the remaining display time at this point, and ends the display control of the message. Also, if the subscriber finishes checking the message during the display time and operates the display switch, the control circuit 6 deletes the message and the display of the remaining display time. On the other hand, if the subscriber operates the mode selection switch when the subscriber wants to move the displayed message to another memory and store it during the display time, for example,
The control circuit 6 shifts from step 2e to step 2i where the message is transferred. When the subscriber operates the message selection switch to display the next four digits and the next four digits in place of the message being displayed, the control circuit 6 shifts from step 2f to step 2j, where the memory is stored. Change the selection so that the new four digits of the message are displayed.

By the way, during the above-mentioned message display time, when the subscriber determines that it is not possible to confirm all the messages within the display time from the remaining display time displayed together with the message on the display 10, and operates the timer switch, the control is performed. The circuit 6 detects this in step 2g and returns to step 2b. And
In this step 2b, the display time is reset in the timer 12. Therefore, the display time of the message is extended, so that the subscriber can continue to check the message.

As described above, according to this embodiment, the remaining display time of the message is displayed during the display of the message, and the display time of the timer 12 is reset when the timer switch is operated to extend the display time. The subscriber can check the message from the remaining display time while checking the message and judge whether or not to end the message, and if not, simply operate the timer switch The display time can be extended with. For this reason, even if the message is long or the confirmation of the message cannot be started immediately after the display is started, the confirmation of the message can be continued without being deleted once. Therefore, it is easy to confirm the message, whereby it is possible to always confirm the message accurately without error. Also,
The operability is also improved since a cumbersome operation for displaying the once deleted message again becomes unnecessary. further,
Since the remaining display time is displayed, the user's uneasiness of not knowing when the display of the message will be deleted is also solved.

The present invention is not limited to the above embodiment.
For example, as a display form of the remaining display time, a normal display form may be used during a period in which the display time is still sufficient, and a blinking display may be performed when the remaining display time becomes short. In this way, the subscriber can be more clearly notified that the remaining display time is short. The display of the remaining display time may be displayed on a display device different from the message. In addition, the control means of the input means of the display time extension instruction, the extension time, the display extension control means, and the like are also included in the gist of the present invention. Various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described above in detail, the selective call receiver and the mobile wireless device according to the present invention erase the display of the message when the display time of the message displayed on the display exceeds a predetermined time. In addition to the means, there is provided a means for displaying the remaining display time of the message during the display of the message.

Further, when a predetermined display extension instruction is input during the display of the message, a means for extending the display operation of the message is further provided.

According to such an invention, for example, even when a long message is displayed, it is possible to continuously confirm the message without erasing the display of the message, thereby facilitating confirmation of the message and improving operability, and It is possible to provide a selective call receiver and a mobile wireless device that can reduce anxiety of use of a subscriber.
