Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an individual selective call receiver with display,
The present invention relates to an individual selective call receiver with a display, which is equipped with an improved display means for dividing and displaying a message, etc., which is longer than the number of characters that can be displayed, on a display device with a limited number of display characters.

[Prior Art] Conventionally, in an individual selective paging receiver (paging receiver) with a display capable of transmitting messages, when displaying message contents on a display device composed of a liquid crystal display board, etc., the maximum number of characters that can be displayed on the display device is As a way to display messages that exceed
Methods of scrolling the display one character at a time and methods of scrolling the display in units of words (a group of characters and symbols separated by spaces are called words) are known. However, these methods have the disadvantage that they require a large number of scrolls and the information is difficult to read. A method to improve this is to divide the message into display screens in units of words, and if a word cannot be displayed in its entirety, it will not be displayed on that screen and will be left blank, and the message will be displayed from the beginning of the next display screen. Special request was made in 1982.
It is proposed in specification No. 151085. With this method, even if multiple words are displayed on the display, they are not displayed all at once on the next screen, but the subsequent words that were not displayed on the previous screen are displayed, reducing the number of scrolls. can do.

[Problems to be solved by the invention]

The display method described in the above specification of Japanese Patent Application No. 151085/1985 is effective in that when a message is composed of a collection of short words, there is less blank space on the display screen and the number of scrolls is reduced. , if the final word displayed on the next screen is long because all characters cannot be displayed, there may be a large amount of blank space compared to the number of characters displayed on the screen, which is wasteful and makes it difficult to understand the connections between sentences. There is also the problem that it is inconvenient. SUMMARY OF THE INVENTION An object of the present invention is to provide an individual selective call receiver with a display that eliminates the above-mentioned problems and can effectively utilize the display area to transmit information.

[Means to solve the problem]

An individual selective calling receiver with a display according to the present invention includes a reception decoding section that selects and decodes an information signal addressed to its own station from received signals, a data memory that temporarily stores the decoded information signal, and contents of the information signal. an individual selective call receiver with a display, comprising: a display for optically displaying characters; and a transfer means for reading out the information signal temporarily stored in the data memory and transferring it to the display for display; means reads out and displays information on the maximum number of characters that can be displayed on the display from the data memory; detection means detects boundaries of each word constituting the information signal and the end of the information; and the display determining means for determining whether all constituent characters of the final word displayed are displayed;
When all of the constituent characters of the final word cannot be displayed on the display, the final word is displayed again on the next display screen starting from the first character.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.
FIG. 1 is a block diagram of an embodiment of the present invention, which includes an antenna 1, a radio section 2, a waveform shaping circuit 3, a decoder section 4, a data memory 5, a display 6, a drive circuit 7, a low frequency oscillator 8, and a speaker 9. , DC.DC converter 10, clock signal oscillator 11, electronic switch 1
2, a battery 13, and a display switch 14. The radio signal received by the antenna 1 is amplified and demodulated by the radio section 2, and then sent to the waveform shaping circuit 3.
The signal is converted into a rectangular wave signal and sent to the decoder section 4. When the decoder section 4 detects the preamble signal, it controls the electronic switch 12, cancels the saving operation of the battery 13, and detects the word synchronization signal and the calling signal. The call signal is sent to the decoder section 4
When the call number matches the call number of the own station written in the PROM of The addressed information signal (8-bit JIS code) is decoded and temporarily stored in the data memory 5. When the detection of the information signal described above is completed and the end signal sent at the end of the received signal is detected, the device returns to the saving operation to prevent battery consumption. Once the information signal is stored in the data memory 5, the information signal is read out when the display switch 14 is operated, and is transferred to the display section 6 and displayed. The display section 6 has a 16-digit liquid crystal panel display constructed from a 5.times.7 dot matrix, which is driven by a drive circuit 7 to internally process input information signals and display the contents in characters.

FIG. 2 is an explanatory diagram showing a specific display example on the display screen of the display unit 6. Above the message display field 15, which can display 16 characters in one line, there is a status display field 16, in which the number of the message being read is displayed. (M1) Other status indications are shown. The decoded information signals are stored in the data memory 5 in order so that they can be read out character by character (including ending symbols and blank spaces), and when the person carrying the receiver presses the display switch 14, the first address (K=1) is stored. Read each character one by one, checking whether it is a space or not, starting with the 16th character (K=16)
The characters up to 1 are displayed at each display position (R=1 to 16) in the message display field 15 as shown in FIG.
Display 7. On the next screen, read out 16 characters (K = 10 to 25) from the first character of the second word that could not display all the constituent characters on the previous screen, and
It is displayed with an intermediate display mark "" 17 as shown in the figure. In Figure 2, the 16th character is exactly the end of the word, and the 17th character is a space, and the next screen displays the next word (K = 27) instead of the space, as shown in Figure 2, and the end symbol Since the display of all messages ends with “ ₀ ”, the intermediate display mark is not displayed. Each screen is configured to change to the next screen after a predetermined period of time (for example, 4 seconds) or when the person carrying the receiver presses a button.
This display method makes effective use of the limited number of characters on the display to convey information, and words that are separated in the middle are displayed again from the first character on the next screen, so there is no chance of misunderstanding. .

FIG. 3 is a flowchart showing an embodiment of the processing procedure for executing the display operation shown in FIG. 2 described above, and the display operation shown in FIG. 2 will be explained in more detail below with reference to this flowchart. In Figure 3, DP is the cumulative number of characters (including spaces) that have already been displayed on the previous display screen than the currently displayed screen;
DS is a word that has already been read before the word currently being read on the same display screen (including spaces)
, WN is the number of characters in the word currently being read, D(K) is the character or symbol read from the Kth position in data memory 5, “□” is a blank space, “ ₀ ” is the end symbol, and R is the end symbol. Indicates the display position (Rth character) of the display, K=DP+
DS+WN, R=DS+WN.

First, the initial setting (K=1) is performed at 100 to 120, and each character (K=1 to K=8) of the first word "123-4567" shown in Figure 2 is stored in the data memory at 130 to 170. The first character (R=1) to the eighth character (R=8) of the display are read out sequentially starting from 5.
will be displayed. Next, when reading and displaying the 9th character space, the DS is updated to R=9 at 180, and the final character "i" of the second word "ABC" is displayed.
The seven characters (K=10 to 16) excluding , are displayed in R=10 to R=16 in the same way as the first word. Here, if you read out the 17th character "i", it will pass through 190 and then 200, which is the status display column 1.
6, an intermediate display mark "" 17 is displayed. When 4 seconds pass after the display or the switch is operated (see 210), DP becomes DP+ after passing through 220 and 230 and reaching 240.
DS=9, and the second
16 characters from the first character of the word (K=10) are displayed. When the display of the third word "Tanakakachiyou" is finished and the 17th character space is read out, an intermediate display mark ""17 is displayed, and this is detected at 220, and at 250, DP is K=DP+DS+WN=
Updated to 9+9+8=26. Therefore, the next screen will not display any spaces and will start with the next character "ni" (K=27) as shown in Figure 2, display the ending symbol "o", and display all messages at 260. end. When the 17th character on each screen is the end symbol "o", the display of all messages is ended at 270 without displaying the intermediate display mark "" 17 and the end symbol " ₀ ". In addition, 280 is the number of characters in one word.
This shows the processing when the number exceeds 16 characters.

In the explanation of the above embodiment, the final word separated in the middle is displayed again on the next screen without any special display, but there is a display indicating that the word is in the middle (midway display mark). “
17), or display the characters ``ABC'' on the screen blinking, add an underline, or reverse the characters, or display the final character (the 16th character ``KA''). Hyphen "-"
If you indicate that it is in the middle of a word by displaying it instead of , the information will be richer.
Further, in the above description, each word is separated by a space, but the same effect can be obtained even if a specific symbol other than a space is used. Incidentally, recent paging systems have been developed in which the paging receiver is equipped with a transmission function and messages can also be transmitted from the paging receiver side, but the wireless selective calling receiver with display function of the present invention has a transmission function. Needless to say, it may be provided with the following.

〔Effect of the invention〕

As explained in detail above, according to the wireless selective calling receiver with display function of the present invention, information is conveyed by effectively utilizing the limited message display field of the display, and the final word separated in the middle is as follows. Since the message is displayed again on the screen, it has the effect of making it easier to understand the contents of the message.
