Abstract

PURPOSE:To attain completion of read of an easy to see character in a short time by transferring several characters altogether and making them stationary for a prescribed time so as to scroll them in reading each information content stored in a storage device by a display device. CONSTITUTION:The read of storage content is started by depressing a push switch (PSW) and applying a command signal U. When the command signal U is applied, whether or not an S register 18 has the storage content is checked by the content of a T counter 17. When it exists, an entry value of a K register 16, that is, the total character number of stored messages is displayed on a display device 4. When a scroll switch ON is detected, a head 16-character of the message corresponding to a stack number is displayed on the display device 4. When the scroll switch is left depressed,the characters are transmitted sequentially by 4 characters each, 3 characters each or two characters each according to the count value of an N counter 22. Thus, the characters are observed more easily than the case with the transmission by one character each and when the total character number is large, the display read time is reduced.

Figure 3 shows C as an example of received data of the selective call receiving device.
POCSAG (Po5t) disclosed in CIR code 爲1
Office Code 5 standard
ionAcivisory Group): This shows a configuration using signals called +- codes.

In FIG. 3, the preamble signal is a 1o10... repeating signal indicating that a signal transfer is being developed. The signal sent following the greamble signal is composed of batch units, each batch consisting of a synchronization signal (SC) and eight frames, and one frame is made up of two code words. Each frame is numbered from flO to #end, and the selective call receivers are divided into eight groups corresponding to the numbers. Code word BC
H(31,21) code (Base-Chaudhuri
-Hocquenghem code, 31 is code length, 2
The signal consists of 32 bits (1 represents the symbol length) plus a 1-bit even parity pit, and is classified into address signals and message signals.

FIG. 4 shows the code structure of the address signal. In the figure, 201 is a recognition flag that identifies an address signal and a message signal, 202 is an address pit that forms an individual selection calling number, and 203 is a 2-bit code that identifies four types of signals. 204 is a parity bit, and 205 is an even parity bit.

Figure 5 shows the code structure of the message signal sent following the address signal.The message signal differs from the address signal in that 20 out of 21 information bits constitute the message information.7) 206 It is divided into three parts.

In this explanation, the selective call receiving device is assigned two address signals, so 203 in FIG.
It is possible to distinguish between 1-A4.81 and B4O in 8 ways, and by making arrangements in advance with the user, business matters, contact information, etc. can be distinguished in 8 ways.

The message signal shown in FIG. 5 is sent in alphanumeric characters (alpha-numeric characters), and one character consists of 7 bits. In FIG. , then the message is frame f
This shows the case where this continues up to #6. Whether it is a message or an address is distinguished by the recognition flag explained in FIG. 4 201.

In one embodiment of the present invention configured as described above, the radio signal received by the antenna 1 is amplified, demodulated, and
After decoding and waveform shaping, the signal is supplied to the control section 3. After the control unit 3 detects the preamble signal, the electronic switch 8 is controlled and the selective call receiving device receives the synchronization signal (SC).
Then, it performs a receiving operation when the frame belongs to its own group. Furthermore, when it detects its own calling number, it determines whether or not a message signal is being sent following the address signal, and if so, the receiving operation continues until the message signal ends. The detection of the synchronization signal and the reception operation of the message signal in the control section 3 are well known in the prior art, and detailed explanation thereof will be omitted. Also, that part is omitted in FIG. 2 as well.

Hereinafter, one embodiment of the present invention will be described in detail with reference to flowcharts shown in FIGS. 7, 8, and 9.

It is checked whether the local station is being called by detecting whether the receiving/discharging (No. 17 matches the own selective calling number stored in the FROM 12) (step 30), and waits for the local station to be called. When your own station is being called, the status of the slide switch 24 is 14.
mode is checked (step 31). The case where N mode is specified will be explained below. It is checked whether or not there is a message in the received data Z (step 32), and if there is no message, the output vanofer memory 24 and the drive circuit 5.6 should be set (step 40). The call destination, for example, °A4'' and 'BEEP' (indicating a sound message) are displayed (step 35).

I knew that it had been received by the alarm sound from the buzzer 6, and the display 4
The display indicates that the call is only a call with no attached message or destination.

Then, when the push switch is pressed and the instruction signal U is turned off, the buzzer 60 will stop sounding, and if the instruction signal U is not applied for 11 seconds, the buzzer 6 will stop sounding when T1 seconds have elapsed, and the display 4 will change. erased (step 3)
6-39).

When the buzzer 6 stops sounding in step 37, it is checked again in step 4 through steps 55 and 56 whether the instruction signal U is being applied, and if it is, the display on the display 4 is turned off and the operation is started. It ends (Stesoge 5
3]. When the instruction signal U is not applied, the display on the display 4 is turned off after just one second has passed, and the operation ends. (Steps 40-41). After the user confirms the above, Puno/
If you press the Yu switch, the display will disappear, but if the Gutshu switch is not pressed, the display will disappear after a certain period of time. If it is determined in step 32 that a message has been added, step 32 is followed by receiving data Z.
The number of characters in the message is counted by the zero counter 15 (step 43), and the called destination data and message in the received data Z are temporarily stored in the temporary message memo j9 (step 44). On the other hand, the call destination data (A1-A4°B1) is stored in the S register in the order received.
~B4) and the gear 2 actuator number of the message are changed and stored. The contents of the message are similarly stored in the message memory.

It is assumed that the S register has 20 stacks, and the called destination data and the number of characters in the old received data are stored in the stack with the highest number. Therefore, following step 44, it is checked by the T counter in step 45 whether the S register in which the next data is stored is full.

The initial condition of the T counter is set to T:20, and the T counter operates so as to be decremented by 1 each time the message is stored in the S register and the message memory.

Therefore, in step 45, T=o, that is, the S register is 20.
In both cases, a check is made to see if a message has already been entered. In the case of T-20, the contents of the stuff 20'' of the S register and the corresponding contents of the message memory 21 are erased (stellar 7'46), and the stack +1111 of the S register becomes empty. A step "1" is added to the T counter (step 47).

Next, in step 45, when T=Q is not the case, that is, when there is an excess memory capacity in the stack, and in step 46
．． When the minimum number position "°1" of the stack is vacated in step 47, the count value of the Kinuta counter 15 is cumulatively added to the register (step 48). It is checked whether the cumulative addition value of the K register 46 is 1200 or more (step 49). This is because the capacity of the message memory 21 is 1000 characters in this embodiment.
This is to check whether the capacity exceeds the capacity of 1.

If the number of characters exceeds 1200 when the number of characters of the message in the newly received data is added, steps 46 to 49 are executed again to prevent the number of characters from exceeding 1200.

When the number of characters is reduced to less than 1200 in step 49, the number of characters of the message in the new received data and the call destination data are stored in the S register 1, and at the same time, the message in the new received data is stored in the message memory 21. (Step 51), the count value of the T counter 17 is -
1° (step 52), the number of characters of the message newly stored in the S register 1B and the call destination data are copied to the output banoff 7 memory 24 (step 53). Memory contents of output buffer memory (A1-A4.B1-B4
identification and number of characters) and 'MESSAGE
” is supplied to the display 4 and displayed, and the buzzer 6 is sounded (step 64).
, already explained steps 36-41゜step 55.5
6.57, the sound is stopped and the display is stopped after confirmation in the same way as when there is no message. Therefore, in this case, the buzzer 6 will notify you that the call has been received, and the display 4 will display the number of characters in the message, the call destination, and the characters in the message.
``MESSAGE'' will be displayed instead.

In this case, if a scroll instruction is given in step 55, the process moves to step 66 and then goes to ``■'' in Figure 8, where the characters of the message contents are sequentially read out. will be explained in detail.

Next, the case where the N mode is designated by the slide switch 24 in step 31 will be explained.

Step 32A checks whether there is a message in the received data Z, and if there is no message, step
A flag is set in the corresponding position of the called destination flag 2o in accordance with the called destination (step 33). In one embodiment of the present invention, the call destination is A1-A4. B1~B4
shall be. Therefore, the number of areas of the call destination flag 20 is eight. Next, the called destination code for which the called destination flag 20 is set and the 'BEEF'' code are outputted to the Banoff 7.
24 (stesoge 34A), and the call destination, for example, lp, 4'-, and 'BEEP'' are displayed on the display 4 (stesoge 35A).The following operations are the same as in N mode. , steps 32A, 35A correspond to steps 32, . Unlike the N mode, the number is not notified by the buzzer.Therefore, the buzzer 6 is not sounded in steps 32A, . . . , 42A, so there are no steps corresponding to steps 36 to 39.

Further, if there is a message, step 43 in which steps 43A and 54A are executed following step 32A.
A, . . . , 54A are steps 43.A in the case of N mode.・
・, 54 are supported. However, in step s1A, compared to step 61, a code indicating the N mode, for example, a code "fvi'" is added, and the number of characters of the message is determined.

The call destination data and the code "M" are stored in the S register 18. Therefore, the display 4 shows the number of characters of the message,
The called party, the letters "MESSAGE" and the code M are displayed to indicate that a message is included and that the call was received in N mode. Note that in the N mode, unlike the N mode, the buzzer does not blow Ill↓. Further, the call destination data and message in the received data are stored in the message memory 21 (step 51A).
~54A).

Next, reading out the stored contents will be explained.

A crow chart for reading is shown in FIG.

For reading, push button is pressed and instruction signal U is sent.
is applied, and when the instruction signal U is applied, the flag of the called destination flag 20 is A1-A.
4. B1 to B4 are sequentially checked to see if they are standing, and the call destination and BEEP corresponding to the hooks that are set are checked.
'' is displayed each time the button is pressed. Also, after the instruction signal U is continuously displayed for T seconds, if it is not being applied, the display disappears and the display ends (step 60~75n.

The above storage contents are all stored in N mode as already explained.

When the instruction signal U is applied in step 73, it is checked in step 76 whether there is any memory content in the S register 18 using the T counter, and if there is no memory content in the S register 18, the received data with a message is sent. has not been received so far, and the display in step 72 is erased and the process ends (steps 78 to 79). When there is a memory content in the S register 18 in step 6, the value set in the K register 16, that is, the total number of characters of the stored message, is displayed on the display 4, and the K register 16 is displayed.
For example, if the value set in K register 16 exceeds 1000 characters, it is displayed by flickering the display character of the total number of characters in step 81. Display on the device 4 (steps 82 and 83). Next, it is checked whether the Gutu7U switch is pressed again, and if it is not pressed, T is pressed.
After seconds (for example, 10 seconds) have elapsed, the display is erased and the reading operation is completed (steps 84 to 86). Step 84
So, if the guts7u switch is on, press S.
One is added to an N counter indicating which stack of registers is to be read. Since the N counter is set to R=o in the initial condition, R==1 and S=1 of the S register, that is, the register containing the latest message, is read and the called destination (A1-A4, 81-B4 ), the number of characters, the text "MESSAGE", and the text "°°M゛°" if stored in M mode (steps 87 and 88). It is checked to see if it has been pressed, and if it has been pressed, the sum of the N counter and T counter is checked to be 20.This means that the number of messages stored in the S register is equal to the number of messages stored in the S register. It is checked whether everything has been read out. If it has been read out, the R counter (rl) is set in step 93, and the display is erased in step 94, ending the process. 87. Returning to 88, the next stack of S registers is read and displayed, and the process returns to step 89. In this case, if the push/u switch is not turned on, it is checked in step 9Q whether the scroll switch is turned on. , if it is not turned on, the display is turned off after T seconds have elapsed by the steshoges 95 and 96, and the display ends.In step 90, the scroll switch is turned on.
When detected, the first 16 characters of the message corresponding to the stack number of the S register of the message memory are displayed on the display 4 by the stesoge 91. Note that the operations from step 50 in the display processing of received data are also connected to this step 9Q. Next, in Step 97A, it is checked whether the Pnonyu switch is ON, and if not, it is checked in Step 97B whether the scroll instruction continues to be ON, and if the scroll switch is kept pressed, the process proceeds to Step 98, where the N counter is Check whether the count value of is less than a predetermined value, for example, n1 (initially N
= o) In the following cases, the count value of the N counter 22 is incremented by ``+2'', the contents of the message memory 21 are advanced by two characters, and the presence or absence of the end mark ``1'' is checked in step 96. If the N counter is not reset to zero using the stethoscope 108, proceed to step 10γ and continue displaying for t seconds, then return to the stethoscope 97A and repeat the already explained operation (step 98゜97).
．． 100). As a result, characters whose number of characters in the message is n1 or less are sequentially sent two characters at a time and displayed. Further, in step 98, if the count value of the N counter 22 exceeds n1''' but is less than or equal to n2''(n2<nl), the count value of the N counter 22 is incremented by +3°;
Advance the contents of the message memory 21 by three characters and repeat the same operation (steps 98, 101, 102, 103).
).

As a result, for characters in a message whose number of characters exceeds nl and is less than or equal to n2, three characters are sequentially sent and displayed. In addition, when the count value of the N counter 22 exceeds ``2'' in the Stesoge 98.101, ``+4'' is added to the count value of the N counter 22, and the message memory 21
Advances the content by 4 characters, displays it for t seconds, and returns to step 97.
A is executed (Stesoge 98, 101, 104-10
7).

As a result, for characters whose number of characters in the message exceeds n2, four characters are sequentially sent and displayed.

Therefore, the characters until the number of characters reaches =I n1 = l are sent two characters at a time and displayed, and the characters exceeding n1" until reaching n21' are sent three characters at a time and displayed, and "n3 Characters exceeding `` will be sent and displayed in 4-character increments. Therefore, it is easier to see than sending one character at a time, and even if the total number of characters is large, it takes less time to display all of them. become.

If the end mark "1" is detected, the count value of the N counter 22 is reset and step 91 is executed again (steps 106 to 208).

Further, by temporarily cutting off the instruction signal U by turning off the scroll switch, it is detected in step 97B, and the N counter 22 is reset (step sy
Two characters are sent at a time starting from the next character at the CL display position, and the text can be read slowly by slowing down the character sending speed in the middle. This concludes the explanation of the read operation,
Next, the switching operation from N mode to N mode will be explained. As shown in FIG. 9, when the slide switch 24 is switched from the x2 position to the x3 position, that is, when the N mode instruction state is changed to the N mode, the S register 18
The display of the code “M” indicating the reception mode in the call destination flag 20 is erased (steps 110 to 1).
14). Therefore, after receiving in N mode, 1. When switched to receive mode or N mode, the code "M" is erased,
Even when displayed, the symbol "M" is no longer displayed.

In the case of the individual selective calling receiver, the operation of the control section 3 gives priority to calling. Therefore, the read routine and the routine for changing from N mode to N mode shown in FIG. 4 are executed while waiting for the local station to be called in step 30 in FIG. 3, and during this execution, the local station is not called. When this happens, the reception operation is given priority,
The read routine of FIG. 4 and the routine of FIG. 4 will be aborted.

Effects of the Invention The present invention has the above-mentioned configuration and provides the following effects.

In a selective call receiver with a display, when each information stored in the storage device is read out on the display device, instead of continuously scrolling characters one by one from the right end to the left end,
The method uses a method of moving several characters at once, standing still for a predetermined period of time, and then scrolling. Because it is configured in
It has the advantage that the characters are easy to see and reading can be completed efficiently and in a short time even when there are a large number of characters.
