DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio receiver having a display function such as a so-called pager.

[0002]

2. Description of the Related Art Conventionally, a radio receiver with a display function such as a so-called pager has been used as a portable device for transmitting and receiving information from a specific place even in a remote place. The user of the pager can be notified of the received message by an alarm, and can obtain further detailed information by making a telephone call or the like according to the message. In recent years, in this type of wireless receiver with a display function, the message storage capacity and the number of functions have been increased. In particular, since services for transmitting messages including characters have become widespread, there is a demand for a receiver capable of storing many messages having a large amount of information. The prior art of such a pager is disclosed in, for example, Japanese Patent Publication No. 58-501569.

FIG. 6 shows a display state of a message. For message (1), received date and time data 1, destination data 2, message content 3, and telephone number 4 are displayed.
In message (2), reception date / time data 1, message content 3 and telephone number 4 are displayed, but destination data 2 is not displayed. In the message (3), only the reception date and time data 1 and the telephone number 4 are displayed, and other information is not displayed. For this reason, a blank portion occurs in the display, and the end mark 5 indicating that the data is completed is also displayed. In message (4), reception date and time data 1
And only the end mark 5 are displayed. In the message (5), received date and time data 1, destination data 2 and message content 3 are displayed. The telephone number 4 is not displayed because of the number of characters that can be displayed on the display means.

[0004] Conventionally, in this type of receiver, the reading and display of messages are performed in chronological order in which the messages are received. For this reason, the already read message and the unread message may be mixed. In addition to displaying the storage location of stored messages, it also displays whether each message has already been read, and it is possible to select and read and display unread messages by operating switches. Receivers are also considered. Many unread messages require urgency, and it is necessary to confirm exactly when and what content the receiver has received.

[0005]

In a conventional receiver, when the number of storable messages increases, old messages that have not been read may be stored in new messages that have already been read. If messages are read and displayed in chronological order by receiving a message by operating a switch or the like, it takes time to search for an old message that has not been read. Also, in a receiver that displays the storage location of a message and whether or not each message has been read, if the number of unread messages is large, the switch operation for message selection becomes complicated. In general, many messages of this kind require urgency, and messages that were originally important may become less important as time elapses after reception. Therefore,
A time stamp, which is an indication of the time of receipt indicating when a message was received, is a very useful additional information. However, the conventional time stamp function is simply added to the message and displayed. If you do not search for the message, the received time is not displayed, and it is determined whether the message is important. Becomes difficult. In particular, as the message storage capacity of the receiver increases and the number of messages increases, retrieval becomes complicated and it becomes difficult to quickly display urgent messages.

An object of the present invention is to provide a radio receiver with a display function that can easily display an unread message and can easily know the reception date and time.

[0007]

According to the present invention, there is provided a radio receiver having a display function for receiving a message signal and displaying the content of the message signal. A determination means for determining, for each message content stored in the storage means, whether or not the message content has already been displayed, and only the message content determined to be not yet displayed by the determination means, are read out from the storage means and displayed. Unread message display means, wherein the unread message display means sequentially displays all message contents not yet displayed among the message contents stored in the storage means for a predetermined time. This is a wireless receiver with a display function.

[0008]

The present invention also provides a method for receiving a message signal,
In a wireless receiver with a display function for displaying the contents of message signals, a storage means capable of storing message contents represented by a plurality of message signals, and whether or not each message content stored in the storage means has already been displayed. Determining means for determining whether the message has not been displayed by the determining means, and reading out only message contents determined from the determining means from the storage means and displaying the list as a list. And displaying a list of a part of the message contents not yet displayed among the message contents stored in the wireless receiver.

Further, in the present invention, the unread message display means displays a reception date and time of the message content stored in the storage means together with a part of the message content.

[0011]

According to the present invention, the determination means determines whether or not each message content stored in the storage means has already been displayed, that is, whether or not the message has already been read, and the unread message display means determines whether the unread message has been read. Since only the read message is read from the storage means and displayed, even if the already displayed message and the unread message are mixed, only the unread message can be easily read and displayed.

The unread message display means sequentially displays the contents of all unread messages for a predetermined time. As a result, the contents of important unread messages can be displayed and read without performing complicated operations.

According to the present invention, the message content is stored in the storage means, and the message content determined to be an unread message by the determination means is displayed as a list by the unread message display means. The unread message display means displays a list of some of the message contents that have not been displayed, so that many unread messages can be recognized at the same time.

In a preferred embodiment of the present invention, the unread message display means displays a list of reception dates and times of the unread messages together with a part of the message contents. This makes it possible to easily determine temporal information relating to reception of an unread message.

Similarly to 107, the mode shifts to the line scroll mode in step a113.

FIG. 3 shows the operation of the radio selective call receiver 10 with a display function shown in FIG. 1 as one embodiment of the present invention. This embodiment is similar to the operation shown in FIG. 2 and is characterized in that the display of an unread message is automatically performed by operating the review switch 20 once. That is, starting from step b200, when the review switch 20 is operated in step b201, a message reading mode is entered, and it is determined in step b202 whether there is a message stored. When there is no message, the process proceeds to step b203, and “No Message
e "is displayed and the process returns to the standby state of step b201.
If there is a message, the process proceeds to step b204, and if there is an unread message, the process proceeds to step b210 and “N
o NewMessage ”is displayed, and step b20 is performed.
The mode is shifted to the normal message display mode of 4B.

When the mode shifts to the unread message display mode in step b204A, a message is displayed in step b205, and the external switches 19 to 21 and the timer are monitored in step b206. The timer monitoring here is intended to automatically perform display scrolling, and the time-out setting time is set to be long enough to read the message information displayed on the display unit 18. The display is scrolled. If the review switch 20 is operated before the timeout, the process proceeds to step b208, and it is determined whether or not there is another unread message. When the scroll switch 21 is operated, the routine proceeds to step b207, where it is determined whether or not the display data exceeds the number of characters that can be displayed on the display 18. In this mode, by operating the review switch 20 and the scroll switch 21, it is possible to scroll without waiting for a timeout. Step b20
When the reset switch 19 is operated in step 6, the process returns to the standby state of step b201. The normal message display mode in step b204B is the same as step a1 in FIG.
The operation is the same as that of the operation 04B.

The determination of whether a message is unread is
This is based on whether the stored message is displayed in the unread message display mode in step a105 in FIG. 2 or step b205 in FIG. For this reason, the message once stored is always displayed as an unread message once.

FIG. 4 shows another embodiment of the present invention.

In step c111, the external switches 19 to 21 and the timer are monitored. When the reset switch 19 is operated or when the timer times out without operating any of the external switches 19 to 21, the process returns to the standby state in step c101. When the review switch 20 is operated, it is determined in step c113 whether or not there is another message. If not, the process returns to the standby state in step c101.
If there is another message, the message is displayed in step c110, and the external switch 1 in step c111 is displayed.
Return to 9-21 and the timer monitoring mode. When the scroll switch 21 is operated, the message 1
In step c1, it is determined whether or not there is a residue not displayed in step 8.
At step 12, if there is any remaining message, the message is scrolled by one line, and the process returns to step c110 to be displayed. If there is no remaining message that is not displayed, step c
At 113, it is determined whether there is another message.

FIG. 5 shows a list display state of unread messages. At step 301, a title screen indicating the unread message list display mode is displayed in order to distinguish it from the normal message display. Next, in step 302, the reception date and time of the unread message and a list of a part of the message are displayed. When all information cannot be displayed on one screen, the screen is automatically scrolled, and when there is no more data, "END" is displayed as shown in step 303.

The determination of whether a message is unread is
It is determined whether or not the stored message information has been subjected to the message display of step c110 in the display mode of step c104B. When a message is to be displayed, a signal indicating that fact is added to the storage data of the message information.

In each of the above embodiments, the message data is stored in the microprocessor 17, but a random access memory, a memory card, or the like is connected outside the microprocessor 17 to store more data. Needless to say, this may be done.
