Description

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

(Prior Art) In recent years, as a new type of selective calling system, a system has been proposed in which a call can be made by sound or light emission, and a message can be transmitted and displayed. In this type of system, for example, when a call request and a transmission message for an arbitrary selective call receiver are sent to a base station, the base station sends a message that encodes the individual number code of the selective call receiver and the transmission message. This selective calling signal is inserted into an empty calling word of the group to which the selective calling receiver belongs and is transmitted. Then, the selective calling receiver receives the selective calling signal and compares the individual number code with the individual number code of the subscriber's own machine, and if the two codes match, the subscriber is informed by a ringing sound or flashing that a call has occurred. At the same time, the message code is decoded and displayed on, for example, a liquid crystal display. If such a system is used, it is very convenient to be able to convey to the subscriber, for example, a contact telephone number or a caller's name as a message.

By the way, selective calling receivers to which such a method is applied generally have an auto-reset function that automatically erases the message display when the message display time reaches a preset predetermined time when a call occurs. . This eliminates the problem of messages being left on the display, thereby preventing the battery from being unnecessarily consumed.

However, with this type of receiver, the above-mentioned auto-reset function causes the display to disappear unconditionally after the display time has elapsed, even if the subscriber is still checking the message.For example, if the message is long, a call may occur. It was difficult to check the message because it was not possible to check it within the period indicated by the time.

Furthermore, once the display disappears, the message display switch must be operated to display the message again, making the operation extremely cumbersome. Furthermore, for inexperienced subscribers, etc., there is a fear of not knowing when the displayed message will disappear while checking the message.
It was difficult to use.

(Problems to be Solved by the Invention) As described above, the conventional selective calling receiver uses an auto-reset function to unconditionally erase the displayed message after a certain period of time, regardless of the confirmation status of the subscriber. Therefore, it is difficult to confirm the message, the operability is poor, and the subscriber is given unnecessary anxiety. To provide a selective calling receiver that allows messages to be continuously checked without being erased, thereby making it easier to check messages, improving operability, and reducing subscribers' anxiety when using the device. It is.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides, in addition to a display erasing means for erasing the message display when the display time of the message displayed on the display device exceeds a predetermined time, means for displaying the remaining display time of this message while it is being displayed, and a display extension means, and the display extension means causes the message to be displayed when a predetermined display extension instruction is input while the message is being displayed. This is designed to extend the action.

(Function) As a result, the subscriber can judge whether or not he or she can finish checking the message based on the remaining display time of the message that is displayed with the message, and if it is unlikely that the subscriber can finish checking the message, the display time can be extended. Even if the message is long or confirmation of the message cannot be started immediately after the start of display, the message is not deleted once and confirmation of the message can be continued as it is. Therefore, it becomes easier to confirm the message, and thereby it is possible to always accurately confirm the message without making any mistakes. Furthermore, since there is no need for a troublesome operation to redisplay a message that has been erased, operability is improved. Furthermore, the anxiety of not knowing when the message display will be erased is also eliminated.

(Embodiment) FIG. 1 shows the configuration of a selective call receiver in an embodiment of the present invention. This selective call receiver first transmits a selective call signal sent from a base station (not shown) to an antenna 1.
After being received by a radio circuit 2 via a mixing circuit 3, the signal is mixed with a local oscillation signal generated from an oscillation circuit 4, frequency-converted, and then demodulated by a demodulation circuit 5. Then, this demodulated selective calling signal is introduced into the control circuit 6, and this $
18 circuit 6 compares the individual number code in the selective call signal with the individual number code of the own machine stored in advance in storage circuit 7, and when both codes match, a sound is output to speaker 9 via drive circuit 8. A sound signal is supplied to generate a sound. At the same time, the message code inserted in the selective call signal is decoded by the control circuit 6, and the decoded message is supplied to the display 10 for display. Incidentally, reference numeral 11 denotes an operation input section for inputting information such as stopping the sound and displaying the message, switching various modes, and selecting the displayed message.

By the way, the control circuit 6 has the functions of collating individual number codes and decoding message codes as described above, as well as display erasure control means 61 and remaining display time display control means 62.
and display extension control means 63. The display erasing control means 61 sets the display time in the timer 12 when the display of the message is started, and erases the display of the message when the time measured by the timer 12 reaches O. 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, while the message is being displayed. The display extension control means 63 is
When the timer switch of the operation input section 11 is operated while the message is being displayed, the display time is reset in the timer 12, thereby extending the message display time.

With such a configuration, when a call occurs to the own machine and the message display control is shifted to, the control circuit 6 switches to the second
As shown in the figure, first, in step 2a, a message is displayed on the display 10. When the message is displayed, the control circuit 6 then sets the message display time in the timer 12 in step 2b to start measuring the display time, and in step 2c, the timer 12 starts measuring the message. The remaining time is displayed on the display 10 along with the above message.
to be displayed.

Now, when the display of the message and its remaining display time is started, the I control circuit 6 monitors the operation of the display switch, the mode selection switch, the message selection switch, and the message selection switch in steps 2d to 2h, respectively. Monitors the operation of the timer switch and the end of the display time.

When the display time set in the timer 12 reaches 0, the control circuit 6 erases the message currently being displayed on the display 10 and the remaining display time, and ends the message display control. Further, even if the subscriber finishes checking the message and operates the display switch during the display time, the control circuit 6 erases the message and the display of the remaining display time.

On the other hand, if the subscriber operates the mode selection switch during the above display time, for example, when he wants to move the displayed message to another memory and save it, the control circuit 6 goes to step 2e and then to step 21. The above message will be transferred here.

Further, 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 moves from step 2f to step 2j and stores the memory therein. change the selection of
This causes the new four digits of the message to be displayed.

Now, during the above message display time, if the subscriber judges from the remaining display time displayed along with the message on the display unit 10 that he will not be able to check all the messages within the display time and operates the timer switch, the control The circuit 6 detects this in step 2g and returns to step 2b. Then, in this step 2b, the display time is reset to the timer 12. Therefore, the display time of the message is extended, which allows the subscriber to continue checking the message.

In this way, in this embodiment, the remaining display time of the message is displayed while the message is being displayed, and when the timer switch is operated, the display time of the timer 12 is reset to extend the display time. This allows the subscriber to judge whether or not he or she can finish checking the message based on the remaining display time while checking the message, and if it does not seem likely to finish, the subscriber can simply operate the timer switch. You can extend the display time. Therefore, even if the message is long or confirmation of the message cannot be started immediately after the message starts being displayed, confirmation of the message can be continued without being deleted. Therefore, it becomes easier to confirm the message, and thereby it is possible to always accurately confirm the message without making any mistakes. Also,
Operability is also improved because there is no need for troublesome operations to redisplay messages that have been deleted.

Furthermore, since the remaining display time is displayed, the anxiety of not knowing when the message display will disappear can be eliminated.

Note that the present invention is not limited to the above embodiments. For example, the display format of the remaining display time may be a normal display format when there is still enough display time, and a blinking display when the remaining display time is running low. In this way, it is possible to more clearly notify the subscriber that the remaining display time is short. In addition, the remaining display time may be displayed on a different display from that of the message, and other means of inputting instructions to extend the display time, extension time, etc.
The control procedure of the display extension control means can also be modified in various ways without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the present invention, in addition to the display erasing means for erasing the display of the message when the display time of the message displayed on the display device exceeds a predetermined time, It includes means for displaying the remaining display time of this message while being displayed, and a display extension means, and the display extension means controls the display operation of this message when a predetermined display extension instruction is input while the message is being displayed. By extending the time period, messages can be continuously checked without being erased under any circumstances.This makes it easier to check messages, improves operability, and improves user convenience for subscribers. It is possible to provide a selective call receiver that can reduce anxiety.
