ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a receiver which receives message information, or a so-called paging receiver (also called a pager).
2. Description of the Related Art
FIG. 26
is a block diagram showing the electrical configuration of a conventional paging receiver
1
. A signal transmitted from an information service carrier by wireless transmission or the like is received by an antenna
4
, and tuned and detected by an RF unit
5
. The detected signal is demodulated and then supplied to a decoder unit
6
.
In the decoder unit
6
, a destination ID code is obtained from a pager format signal of, for example, the POCSAG system, and it is judged whether the ID code coincides with the own ID code stored in an ID-ROM
7
or not. If the codes coincide with each other, message information is obtained from a signal which is subsequently received. Furthermore, an interrupt signal indicative of reception of an effective signal is outputted.
In response to the interrupt signal, a control unit
2
activates operation programs which are previously stored in a program memory
3
, such as those for processes of storing and displaying the received message. The received message information is stored in a received message storing unit
8
, and displayed on an LCD (liquid crystal display)
10
which is driven by an LCD driver
9
.
When execution of a process such as message deletion is instructed through a key input unit
11
, the process such as deletion is conducted on the received message. A vibration generating unit
12
notifies the user of reception of a message by a vibration, and an alarm/melody sound generating unit
13
acoustically notifies the user of reception.
The control unit

, the key input unit
11
, the vibration generating unit

are electrically connected to each other via a bus line

in the case where the message
15
is displayed on the LCD
10
. In the paging receiver
1
, a data indicative of the reception date and time is stored together with the message
15
in the received message storing unit
8
. Therefore, the reception date and time is displayed on the LCD
10
in addition to the message
15
.
Since the display capacity of the LCD
10
is limited, the whole of a message is not always displayed. A message number
18
, the message
15
, and the reception date and time
19
are set to be total data to be displayed. A display virtual area
17
which includes these data is assumed. As shown in
FIGS. 28A
to

C, in the actual display screens
16
a
to

which are smaller than the display virtual area
17
, the data are displayed in a split manner.
The display screens

are switched over by operating a display message downward button

and a display message upward button

Another example of a pager of the prior art is disclosed in Japanese Unexamined Patent publication JP-A 7-131840 (1995). The pager is provided with a ROM for classifying received messages in accordance with the contents, so that the stored received messages can be quickly searched. Specifically, messages are classified by the kind of the end of a sentence. For example, a message ended by “KUDASAI (please)” is stored as “Instruction” category, that ended by “SHIMASU (will do)” is stored as “Memo” category, and that ended by “TAI? (would you?)” is stored as “Question” category.
In accordance with increasing requests of the user for the variety and amount of information, the paging service is advancing so as to provide a wide variety of and a large amount of information. In a paging receiver, the capacity of a memory for storing received messages is made larger. It is difficult to select a necessary message from such a large amount of received messages.
In the pager disclosed in Japanese Unexamined Patent Publication JP-A 7-131840 (1995), all received messages are stored, and it is difficult to select a necessary message as described above, thereby producing problems in that the operability is lowered, and the memory capacity is wastefully used. Moreover, the pager has a further problem in that necessary messages cannot be stored in an increased number.
Furthermore, messages are classified only by the kind of the end of a sentence. In order to correctly classify a message, the sender of a message must prepare the message in consideration of this classification system. If such consideration is not sufficiently performed, there arises a disadvantage that the message cannot be classified. Since a ROM is used for classification, the user cannot freely change the classification category.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a receiver capable of selectively storing a desired message among all received messages. It is another object of the invention to provide a receiver capable of storing among all received messages, a desired message as distinguished from the other messages.
The invention provides a receiver which receives a message transmitted from a terminal device and stores the received message in message storing means, comprising:
keyword setting means for setting a predetermined keyword;
keyword storing means for storing the preset keyword;
judging means for, when a message is received, judging whether the received message contains the keyword stored in the keyword storing means or not; and
controlling means for storing only a received message which is judged by the judging means to contain the keyword, in the message storing means.
According to the invention, among received messages, only a message containing the predetermined keyword is stored. Therefore, only necessary messages can be selectively stored, the operability is improved, and the wasteful use of the memory capacity is reduced. Furthermore, a larger number of necessary received messages can be stored. Since the keyword can be arbitrarily set by the user, the kind of a message to be stored can be freely selected.
The invention provides a receiver which receives a message transmitted from a terminal device and stores the received message in message storing means, the receiver comprising:
keyword setting means for setting a predetermined keyword;
keyword storing means for storing the set keyword;
judging means for, when a message is received, judging whether the received message contains the keyword stored in the keyword storing means or not; and
controlling means for storing a received message which is judged by the judging means to contain the keyword, in the message storing means as distinguished from other received messages.
According to the invention, among received messages, a message containing the predetermined keyword is stored as distinguished from other received messages. Therefore, a received message of high importance can be stored as distinguished from other received messages, thereby improving the operability. Since the keyword can be arbitrarily set by the user, the kind of a message of high importance can be freely selected.
The invention is characterized in that:
the keyword storing means stores a plurality of keywords,
the judging means judges whether the received message contains the keywords stored in the keyword storing means or not, and the controlling means stores only a received message which is judged by the judging means to contain all of the plurality of keywords, in the message storing means.
According to the invention, among received messages, only a message containing all of the plurality of predetermined keywords is stored. Therefore, only necessary messages can be selectively stored with the result that the operability is improved and the wasteful use of the memory capacity is reduced. Furthermore, a larger number of neces
