BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. First, the circuit configuration is shown in FIG. Reference numeral 11 denotes an antenna, and the radio wave of the call including the message received by the antenna 11 is sent to the wireless unit 12. The radio section 12 is for performing intermittent reception by driving the decoder section 13, and amplifies and demodulates a received radio wave and sends it to the decoder section 13. The decoder unit 13 determines whether or not the called number matches its own identification number, and if they match, which identification number of its own was the number called together with the call detection signal. Alternatively, it sends to the CPU 14 call type information indicating what kind of call was added to the call number and message information received subsequently to the call number. The CPU 14 controls the operation of the entire other circuit in accordance with the signal from the decoder unit 13 and the input signal from the switch input unit 15, and is controlled by a ROM storing various control programs, a timer, an arithmetic register or the like. Composed. The switch input section 15 includes a main switch 16 for controlling power on / off, a reset switch 17 for instructing to release a sound or a message in the middle, and a protect mode or message for protecting message information. -Mode selection switch 18 for selecting modes such as delete mode for erasing data, printout mode for printing out stored message information, etc. Execution switch 19 for instructing the execution of the operation, memory bank switch 20 for instructing the sequential display of stored message information, print mode selection switch 21 for selecting the print contents in the print out mode, and ringing tone. A volume switch 22 for adjusting the volume of the
Send to PU14. The CPU 14 is connected to a clock unit 23 that performs a timekeeping operation, a RAM 24 that stores a plurality of message data and control data, and stores the received message information and the like in the RAM 24 together with the time data. The sound emission signal is sent to the speaker 26 via the amplifier 25, and the LED 28 is sent via the amplifier 27.
A lighting signal is sent to each to notify that there is a call. Then, the CPU 14 outputs and displays display data such as message information on a display unit 29 composed of a liquid crystal display element, and prints data on a printer 31 connected via an external terminal 30. Output data and print it out.

When the main switch 16 is turned off,
The power supply to all the circuits other than the CPU 14, the switch input unit 15, the clock unit 23, and the RAM 24 is stopped. The display unit 29 has a display pattern as shown in FIG. 2, for example.
In the figure, the display unit 29 has a message display unit 29a for displaying message information in alphanumeric characters, kana, hiragana and kanji.
In addition, the protect mode display 29b for notifying that the protect mode has been entered, the delete mode display 29c for notifying that the delete mode has been entered, and the printout mode have been entered. There is a print-out mode display 29d that informs that the time adjustment mode display 29e has been notified that the time adjustment mode has been entered, and there is message information that has not been displayed even once, and therefore it is still checked. An unconfirmed (undisplayed) display 29f that indicates that there is message information that has not been displayed, a protected message display 29g that indicates that the displayed message information is protected message information, and a power supply The voltage drop indicator 29h that indicates that the battery is exhausted, the volume indicator 29i that indicates where the volume switch 22 is currently located, and the No of the displayed message information. Message displays the type information of a call - di No and call type display unit 29j is disposed. The message display section 29a, the message No. and the call type display section 29j are both composed of a dot matrix. The message display section 29a has 12 full-width characters x 2 lines, and the message No. Also, the call type display portion 29j can display the same three characters.

In the RAM 24, the management data memory 24a shown in FIG. 3A, the message memory 24b shown in FIG. 3B and a bank counter, a non-display flag counter, a flushing flag register, a mode counter, Print mode
A counter, a processed flag register, an initial state flag register and the like are provided.

As shown in FIG. 3A, a management data memory
The reference numeral 24a stores management data for managing message information. The management data includes a protect flag indicating whether or not the message information is protected, a non-display flag indicating whether or not the message has not been displayed yet, a sound emission being stopped in the middle of sound emission. A reset flag indicating whether or not the reset switch 17 has been operated, information indicating the type of call, a bank number indicating a storage area of message information in the message memory 24b, and a date and time at the time of incoming call as one set. A plurality of sets, for example, 30 sets of management data are stored in the management data memory 21a as LI.
It is stored in the FO system.

On the other hand, as shown in FIG. 3B, the message memory 24b pairs the actually received message information with the error information indicating which block of the message information has an error. A plurality of sets, for example, 30 sets are stored by page management.

Here, the radio signal is received by the antenna 11 and
The configuration of the selective call signal demodulated by the above will be described.
For example, the selective call signal of the POCSAG system, which has become an international standard, is composed of a header part for synchronizing bit units called a preamble, and a data part called one or more N consecutive batches. This one batch is a synchronous code
It consists of a dword and 8 subsequent frames, and one frame consists of two codewords. There are two types of codewords, an address (ID-number) codeword and a message codeword, both of which are composed of 32 bits.

The address codeword is a codeword for a calling number (address). The address code consists of an 11-bit address bit with the first bit set to "0", and a 2-bit address bit. Function bits and 11 parity bits are added. The function bit is call type information added to the call number, and four types of calls called multi-address calls can be distinguished by this bit, and 4 different numbers can be assigned to one ID.
Various types of sounds and indications (indicated by symbols “A” to “D”) can be made.

On the other hand, the message code word is a message message.
A codeword for message information, a message bit consisting of 21 bits with the first bit set to "1" and 1
It consists of one parity bit, and if there is a message, it is transmitted following the address codeword.

Next, the operation of the above embodiment will be described. Now, when the main switch 16 is turned on, its operation signal is sent from the switch input section 15 to the CPU 14, and the wireless section
12, decoder section 13, amplifier 25, speaker 26, amplifier 27,
The power supply to the LED 28 and the display unit 29 is started, and the CPU 14 starts the process shown in FIG.

In FIG. 4, first, each circuit is initialized as shown in step A01. Here, the display contents of the display unit 29, the timer inside the CPU 14, the bank counter inside the RAM 24, etc. are initialized. Then, proceed to step A02,
Read the input signal from the switch input section 15, reset switch 17, mode selection switch 18, execution switch 19,
It is determined whether any one of the memory bank switch 20, the print mode selection switch 21 and the volume switch 22 has been operated. Thereafter, it is determined in step A03 whether there is an incoming call. If it is determined that there is no operation, the process proceeds to step A04, and it is determined whether or not the memory bank switch 20 has been operated according to the result of reading the operation switch in step A02. If it is determined that the memory bank switch 20 has not been operated, it is next determined at step A05 whether or not the mode selection switch 18 has been operated. If it is determined that the mode selection switch 18 has not been operated, the process returns to step A02. That is,
In the normal standby state, an appropriate time interval is set and step A02
To A05 are repeatedly executed.

If it is determined in step A03 that there is an incoming call, the process proceeds to step A06 to perform incoming call processing.
This incoming call processing includes the incoming call data received by the antenna 11 and demodulated by the wireless unit 12, and then decoded by the decoder unit 13, and the date and time measured by the clock unit 23 at that time. , RA after confirming that it is not the second data by the repeat call transmitted within a predetermined time, for example, 60 seconds.
Store it in M24.

In this case, as the incoming call data, the above-mentioned call type information, message information indicating the content of the message when there is a message code and its error information are stored. . The message information of the incoming data and its error information are stored in the empty bank of the message memory 24b, but the call type information and the incoming date and time are managed by the management data.
Message memory in which incoming data already stored in data memory 24a is processed by shifting by one bank and the message is stored.
It is stored in the first bank together with the bank number of 24b.

At the same time, the undisplayed flag "1" which is reset when a message is displayed in the reading process which will be described later is set in the undisplayed flag register of the first bank, and the unconfirmed display member is displayed. The count value of the non-display flag counter used for the lighting control of 29f is incremented by "+1".

At this time, if 30 sets of data have already been stored in the management data memory 24a, the oldest ones are sequentially erased by the shift process. 1 ”data and“ 0 ”
, The undisplayed flag and the protect flag are “0”, that is, the message information has been confirmed, and the data is not protected.
Next, data whose protect flag is "0", that is, data whose message information is unconfirmed but not protected
The shift processing is performed in such a manner that data is erased in the order of data.

Here, out of 30 sets of data, the number of message data which can be protected by setting the protect flag to "1" is defined to be, for example, 20 sets. If 30 sets of data have already been stored in the management data memory 24a and 20 sets of them have the protect flag "1" set, the remaining 10 sets are oldest first. The shift process will be performed in the form of erasing.

After storage in RAM 24, drive speaker 26 via amplifier 25 to indicate that there was a call,
Start sounding (sound emission). In this case, the sounds are different depending on the type information of the call. At the same time, the LED 28 blinks via the amplifier 27, the unconfirmed (undisplayed) display 29f of the display 29 is lit, and the message "Incoming call" is displayed on the message display 29a. The display processing is performed and the timer for counting the display time is started.

Then, the display is displayed until the reset switch 17 is operated or a predetermined time, for example, "8" seconds has elapsed, and whether the reset switch 17 is operated or a timer is displayed.
When the measured time reaches a predetermined “8” seconds and the time is up, the display on the display unit 29 and the LED 28 is turned off, and the incoming call process is terminated.

The incoming call processing is performed as described above, the sounding and display processing is performed, and the incoming call data is stored in the RAM 24. The incoming call data stored in the RAM 24 is followed by the step A when it is determined that the memory bank switch 20 is operated in the step A04 in FIG.
At 07, the reading process is performed.

When data is read by the reading process, the normal mode in which incoming data is sequentially displayed each time the memory bank switch 20 is operated, and the memory bank switch 20 is operated continuously for two seconds or more. There is a search data mode in which the mode is set by searching and the undisplayed incoming data among the incoming data stored in the RAM 24 is retrieved and displayed.

At the beginning of the processing, first, a two-second timer for measuring the operation time of the memory bank switch 20 in the CPU 14 and a 30-second timer for measuring the display time of the data are started to initialize the bank counter. After setting the value "1",
As a normal mode, the incoming call data is read according to the count value of the bank counter, and the incoming call data, that is, call type information and message information is displayed on the display unit 29 together with the incoming call date and time information.

Here, if the message information is undisplayed message information, that is, in the undisplayed flag register of the corresponding bank of the management data memory designated by the count value of the bank counter. When the flag "1" is set, this flag is reset, the count value of the non-display flag counter is set to "-1", and the message No. and the call displayed on the display unit 29j are displayed. Flash the classification symbol.

The displayed message information is an error.
If the message information has a message,
The display digit portion designated by the error information stored in the message memory 24b corresponding to the message information is displayed in reverse video.

After the data is displayed, the reset switch 17 for instructing to stop the display or the memory bank switch 20 for instructing to display the next incoming data is operated, or a 30 second timer-2 seconds timer- Will continue to display until the time is up. If the 30-second timer expires,
Since the display for a predetermined time has been completed, the display is turned off, and if the search mode is set, the mode setting is also turned off, and the reading process is completed.

Also, when it is determined that the reset switch 17 has been operated during the display, the reset switch 17
The display is turned off and the mode setting of the search mode is turned off in accordance with the operation of, and the reading process is completed.

When the 2 second timer times out,
The memory bank switch 18 is operated continuously for 2 seconds or more,
Since the setting of the undisplayed search mode has been instructed, after setting that search mode, the count value of the bank counter is updated and set to "+1", and then the next incoming data is set. -Repeat the operation from the above data display after confirming that the data is undisplayed data.

When the memory bank switch 20 is newly turned on during the data display, the instruction is to prompt the display of the incoming data of the next bank. After resetting the timmode and restarting the timing operation of the 2 second timer and the 30 second timer,
The count value of the bank counter is updated and set to "+1", and the next incoming data, that is, incoming data that arrives immediately before the currently displayed incoming data is displayed according to the count value.

Thus, in the normal mode, each time the memory bank switch 20 is operated, the
In the Tim mode, only undisplayed incoming data is stored in RAM24.
Can be selected and displayed.

The above shows the incoming call process and the read process in the normal mode. It is assumed that the mode selection switch 18 for instructing the mode change is operated in step A05 of FIG. If so, then proceed to Step A08, where
A switch selection process is performed. This mode selection processing is performed by R
Updates and sets the count value of the mode counter provided inside the AM24. The mode counter is composed of a normal mode, a protect mode, a delete mode, a print-out mode, and a quinary counter indicating five mode states, and a count value. "0" for normal mode, "1" for protect mode, "2" for count mode
The delete mode, the printout mode with the count value "3", and the time adjustment mode with the count value "4".
, Respectively. Therefore, the mode in the normal mode
The count value of the mode counter is "0", and when the mode selection switch 18 is operated once to reach step A08 from step A05, the mode selection processing is performed.
The count value of the counter is updated and set to "+1" and becomes "1". Corresponding to the count value of this mode counter, the processing corresponding to the mode selected in the following step A09 is performed, and after the processing, the processing from step A02 is repeated again.

Now, it is assumed that the reception standby state is in the normal mode in which the processes of steps A02 to A05 are repeatedly executed. At this time, in the display unit 29, in order to minimize the power consumption of the selective call receiver with a display function having a limited power capacity, the driving of all the display bodies 29a to 29i is stopped as shown in FIG. doing. When the mode selection switch 18 is operated in such a state, this is judged in step A05, and then step A08 is reached. RAM in step A08
The count value of the mode counter in 24 is changed from “0” to “+”.
1 "is updated and set to" 1 ", and in the following step A09, the protect mode shown in FIG.
Is performed.

In FIG. 6, first, as shown in step B01, the time of the 8-second counter in the CPU 14 in which the minimum mode display time "8" seconds is set is set and started. Then, in step B02, the display unit 29 displays that the protection mode has been changed.
In this case, on the display unit 29, as shown in FIG. 5B, the message "Protect mode" is displayed on the message display unit 29a, while the protect mode display unit 29b is driven to light. At the same time, RA is determined by the contents of the bank counter.
The call type information of the newest message information stored in the first bank of the management data memory 24a in M24 is read out, and this is read out as a message number and call type display portion 29j.
Is displayed, for example, as "01C".

Thereafter, in step B03, the above-mentioned 8-second timer
Whether or not the reset switch 17 has been operated in step B04, the mode selection switch 18 has been operated in step B05, the execution switch 19 has been operated in step B06, and In step B07, it is continuously determined whether or not the memory bank switch 20 has been operated. If it is determined that the answer is NO in any of these cases, the process returns to step B03.
The process waits for a switch operation input while repeating the process of B07.

If it is determined in step B03 that the 8-second timer has timed out, the switch operation in this protect mode is not performed for 8 seconds, and similarly, the display of this protect mode is continued. Even if it is determined that the switch operation has not been performed, the process proceeds to step B08 and the reset process is performed such as resetting the contents of the mode counter to "0". In response to this, the display also returns from the display state of the protect mode shown in FIG. 5 (B) to the standby state of the normal mode of FIG. 5 (A), as shown by the arrow TU, and the processing is completed. .

Also, when it is determined in step B04 that the reset switch 17 has been operated, in order to release the protect mode in accordance with the operation of the reset switch 17, the process proceeds to step B08 similarly to the above, and the mode counter is operated. Content is reset to "0", and in response to this, the display changes from the display state of the protect mode shown in FIG.
As shown by U, the process returns to the standby mode in the normal mode shown in FIG.

In step B05, a mode selection switch
When it is determined that 18 has been operated, the count value of the mode counter is updated and set to "+1" in step B09 in response to this switch operation, the mode is converted to the delete mode, and the display is displayed. After the display state shown in FIG.
This is the end of the process.

In step B07, the memory bank switch
If it is determined that 20 has been operated, then the count value of the bank counter is set to "+1" in step B10, and the count value updated in step B11 is set to RA.
It is determined whether the number of incoming data stored in M24 is exceeded.

If it is judged that the time is not exceeded, the display time of the message information is counted in the following step B12 3
The 0-second timer is set and started, and at the same time, RA is performed according to the count value of the bank counter in step B13.
Incoming data such as corresponding message information is read from M24 and displayed on the message display section 29a of the display section 29 or the like.

Thereafter, this message display is continued until it is judged at step B03 that the 30-second timer has timed up, or at step B03 to B07 that each switch is operated.

If it is determined that the count value of the bank counter updated and set in step B11 exceeds the number of incoming data stored in the RAM 24, the process proceeds to step B14 and the bank is restarted. After setting the initial value "1" in the counter, the process proceeds to step B12.

When the memory bank switch 20 is operated to select and display the message information to be protected as described above, and the execution switch 19 for instructing the execution of the data protection process is operated, this is a step. If the protect flag "1" is set in the bank of the management data memory 24a currently designated by the bank counter, that is, if the message currently being displayed has already been detected. Protected Messe
It is determined whether or not it is.

If it is determined in step B15 that it has not been set, the process proceeds to step B16. At step B16, it is determined whether or not the designated message information can be protected, that is, the management data memory 24a of the RAM 24 has already been protected.
It is determined whether the number of protect flags set in is less than 20 or not.

If it is judged that protection is possible, then the procedure proceeds to step B17, where the protect flag "1" of the corresponding message information is set, and then the 8-second timer is set at step B18, and the start flag is set. At the same time, the display 29
In the message display area 29a of, for example, a message such as "The message is protected." Is displayed. Thereafter, the processing from step B03 is performed, and the protection completion display is continued until the 8-second timer expires.

If it is determined in step B16 that protection is impossible, that is, if 20 sets of message information have already been protected, the process proceeds to step B20 and the 8-second timer is also set. At the same time as setting and starting, at step B21, a message such as "Protection capacity is full." Is displayed on the message display section 29a of the display section 29 as an unprotected display. Thereafter, the processing from step B03 is performed, and the non-protection display is continued until the 8-second timer expires.

On the other hand, if it is judged at step B15 that the protect flag "1" is set, then the processing advances to step B22, at which the protect flag is reset, and then at step B23 an 8-second timer is set to start the timer. At the same time, the message "Protection has been released" is displayed on the message display section 29a of the display section 29 as the protection release completion display in step B24. This protection release processing is performed when a message that originally does not need to be protected is mistakenly protected, or when it is determined in step B16 that protection is impossible, and in step B24 the protection release completion message is displayed. After the start, the process returns to step B03, and the protection release completion display is continued until the 8-second timer expires or the switch operation is detected in steps B04 to B07.

Next, as shown in step B09, the mode select switch 18 is operated from the protect mode to update and set the count value of the mode counter to "2",
The delete mode processing after switching to the delete mode will be described with reference to FIG.

In FIG. 7, first, as shown in step C01, the time of the 8-second counter in the CPU 14 in which the minimum mode display time "8" seconds is set is set and started. Then, in step C02, the display unit 29 displays the delete mode indicating that the mode has been changed. In this case, on the display unit 29, as shown in FIG. 5 (C), the message "Delete mode" is displayed on the message display unit 29a, while the delete mode display unit 29c is driven to light. . Along with this, the call type information of the message information stored in the corresponding bank of the management data memory 24a in the RAM 24 is read according to the contents of the bank counter, and this is read in the message number and the call type display section 29j. , For example, "0
1C ”is displayed.

Thereafter, in step C03, the above-mentioned 8-second timer
Whether or not the reset switch 17 has been operated in step C04, the mode selection switch 18 has been operated in step C05, the execution switch 19 has been operated in step C06, and In step C07, it is continuously determined whether or not the memory bank switch 20 has been operated. If it is determined that the answer is NO in any of these cases, the process returns to step C03.
The process waits for a switch operation input while repeating the process of C07.

If it is determined in step C03 that the 8-second timer has timed out, the switch operation in this delete mode is not performed for 8 seconds, and the display of this delete mode is continued. It is determined that the switch operation will not be performed even if you continue with step, and then step C08.
Then, the mode reset processing such as resetting the content of the mode counter to "0" is carried out. In response to this, the display also returns from the display mode of the delete mode shown in FIG. 5 (C) to the standby mode of the normal mode shown in FIG. 5 (A), and this processing is completed. To do.

Also, when it is determined in step C04 that the reset switch 17 has been operated, in order to release the delete mode in accordance with the operation of the reset switch 17, in the same manner as described above, the process proceeds to step C08 and the mode is reset. The content of the counter is reset to "0", and the display is changed accordingly.
From the display mode of the delete mode shown in (C), as shown by the arrow TU, the display returns to the standby mode of the normal mode of FIG.
This is the end of the process.

In step C05, a mode selection switch
If it is determined that 18 has been operated, the count value of the mode counter is updated and set to "+1" in step C09 in response to this switch operation, and the mode for printout mode is set.
After the conversion is performed to bring the display into the display state shown in FIG. 5 (D), this process ends.

In step C07, the memory bank switch
If it is determined that 20 has been operated, then it is determined in step C10 whether the flag "1" has been set in the display control processed flag register in the RAM 24.

If it is determined that the data has been set, it means that the incoming data has already been deleted at the time before that, so the process proceeds to step C11 and the RAM 24
Of incoming data stored in the management data memory 24a
At the same time that the processing is performed, the number of stored incoming data is updated to "-1" and the processed flag register is reset to "0".

In step C10, the processed flag "1" is set.
If it is determined that is not set, step C12
Then, the count value of the bank counter is updated and set to "+1".

After the processing of step C11 or step C12, it is determined whether or not the count value of the bank counter exceeds the number of incoming data stored in the RAM 24.
If it is determined that the time is not exceeded, the 30-second timer that measures the display time of the message information in the following step C14
And at the same time the start is started, the incoming data such as corresponding message information is read from the RAM 24 in accordance with the count value of the bank counter in step C15, and the display unit 29
Is displayed on the message display section 29a or the like.

Thereafter, in step C03, this message display is continued until it is determined that the 30-second timer has timed up, or in steps C03 to C07 that each switch has been operated.

If it is determined in step C13 that the count value of the bank counter updated and set exceeds the number of incoming data stored in the RAM 24, the process proceeds to step C16 and again. After setting the initial value "1" in the bank counter, the process proceeds to step C14.

After the memory bank switch 20 is operated to select and display the message information to be deleted as described above, the execution switch for instructing the execution of the delete process
When 19 is operated, this is determined in step C06, and then the process proceeds to step C17. In step C17, the RAM
It erases designated message information in the 24 management data memory 24a and the message memory 24b and other corresponding data. After that, in step C18, the processed flag "1" is set, then in step C19, a 30-second timer is set and started, and at the same time, in step C20, a message on the display unit 29 is displayed as a delete completion display. For example, a message "Message has been erased." Is displayed on the message display portion 29a. After that, the processing from step B03 is performed, and this delete completion display is continued until the 30-second timer expires.

Then, as shown in step C09, the mode select switch 18 is operated from the delete mode to update and set the count value of the mode counter to "3".
The printout mode process after switching to the printout mode will be described with reference to FIG. At this time, the printer 31 is securely connected to the external terminal 30.

In FIG. 8, first, as shown in step D01, a partial print mode, a protect text print mode, a full text print mode and a partial print mode among three print modes.
Set the print mode that prints only the displayed message data. At the same time, a flag "1" is set in an initial state flag register provided in the RAM 24. This initial state flag register is for limiting the selection operation from the above three print modes only to the initial setting of the print out mode.

Thereafter, at step D02, the 8
Set the time of the second counter and start it. Then, in step D03, the display section 29 displays that the mode has been transferred to the printout mode. In this case, the display unit 29 displays the message display unit 29 as shown in FIG.
The characters "print out mode" and the characters indicating the three print modes "partial", "protection sentence", and "full sentence" are displayed in a. In this case, "partial print" is initially set as the print mode, so that only the characters "partial" are highlighted. Along with this, the printout mode display unit 29d is driven to light. further,
Depending on the contents of the bank counter, the call type information of the message information stored in the corresponding bank of the management data memory 24a in the RAM 24 is read out, and this is displayed in the message number and the call type display portion 29j, for example, "01C". Is displayed.

Thereafter, in step D04, the 8-second timer
Whether the time has expired, whether the reset switch 17 has been operated in step D05, whether the mode selection switch 18 has been operated in step D06, and the print mode in step D07.
It is continuously determined whether the mode selection switch 21 has been operated, whether the execution switch 19 has been operated at step D08, and whether the memory bank switch 20 has been operated at step D09. If NO is determined in any of these cases, the process returns to step D04, and waits for a switch operation input while repeating the processing of steps D04 to D09.

If it is determined in step D04 that the 8-second timer has timed out, this printout mode
The switch operation in the mode is not performed for 8 seconds, and it is judged that the switch operation is not performed even if the display of this printout mode is continued, and the process proceeds to step D10 and the contents of the mode counter. Is reset to "0" or the like. In response to this, the display returns from the printout mode display state shown in FIG. 5D to the normal mode standby state shown in FIG. 5A, as indicated by arrow TU, and the processing ends. To do.

Also, when it is determined in step D05 that the reset switch 17 has been operated, the printout mode is canceled in accordance with the operation of the reset switch 17 in the same manner as described above, the process proceeds to step D10. The contents of the mode counter are reset to "0", and accordingly, the display is changed from the display state of the printout mode shown in FIG. 5 (D) to the normal mode of FIG. 5 (A) as shown by an arrow TU. The process returns to the standby state of and the process ends.

In step C06, a mode selection switch
If it is determined that 18 has been operated, the count value of the mode counter is updated and set to "+1" in step C11 according to this switch operation, the mode is converted to the time adjustment mode, and the display is displayed. After the state shown in FIG. 5 (E), this process ends.

If it is determined in step C07 that the print mode selection switch 21 is operated, then it is determined in step C12 whether the flag "1" is set in the initial state flag register of the RAM 24. .

If it is determined that the setting has not been made,
Since the execution switch 19 or the memory bank switch 20 is operated after the flag "1" is set in step D01, the operation of the print mode selection switch 21 is invalidated, and the process returns from step D04. If it is determined that the print mode counter is set, the count value of the print mode counter is updated and set in step D13. From the partial print mode to the protect text print mode, the protect text print mode is set. The print mode is switched to the full-text print mode or from the full-text print mode to the partial print mode, and the characters in the corresponding message display area 29a are displayed in reverse video.

Thereafter, the process proceeds to step D14, in which a 30-second timer is set and started in order to continue the display of the switched print mode for a predetermined time, and thereafter step D04 is performed.
To processing.

When the memory bank switch 20 is operated in order to select and print a specific message data, this is judged in the above step D09, and then step D15 is reached. At step D15, it is judged from the contents of the print mode counter whether the current print mode is the partial print mode.

If it is determined that the print mode is not the partial print mode, the operation of the memory bank switch 20 is invalid, and the process returns to step D04, but it is determined that the print mode is the partial print mode. Then, in step D16, the count value of the bank counter is updated and set to "+1" in response to the operation of the mode selection switch 18, and the initial state flag register is reset.

Then, in step D17, it is judged whether or not the updated count value of the bank counter exceeds the number of incoming data stored in the RAM 24.
If it is determined that the time has not exceeded, the next step D18 is 30
The second timer is set and started, and at the same time, the RAM is read according to the count value of the bank counter in step D19.
Incoming data such as corresponding message information is read from 24 and displayed on the message display section 29a of the display section 29 or the like.

Thereafter, this message display is continued until it is judged at step D04 that the 30-second timer has timed up, or at step D04 to D09 that each switch is operated.

If it is determined in step D17 that the count value of the bank counter exceeds the number of incoming data stored in the RAM 24, the process proceeds to step D20, and the bank counter is re-established. After setting the initial value "1", the process proceeds to step D18.

When the execution switch 19 that is actually instructed to execute printing is operated, it is determined in step D08 that the execution switch 19 is on by this operation input, and the process proceeds to step D21. In step D21, a message indicating that printing is in progress, for example, "printing in progress" is displayed on the message display section 29a of the display section 29. Next, in step D23, the value of the bank counter at that time is written in an internal register of the CPU 14 for temporary saving, and then the process proceeds to step D24 to execute a printing process.

FIG. 9 is a subroutine showing details of the printing process.
Chin. In the figure, first, at step E01, it is judged if the print mode is the partial print mode. If it is the partial print mode, the process proceeds to step E02, and the printer 31 prints out only the message data displayed in step D19 of FIG.

That is, the printout data includes a message No. (bank No.), call type information, presence / absence of non-display flag, presence / absence of protect flag, reception date / time, message.
Information.

When the message information is message information with an error, that portion is printed in black and white inversion as in the case of display based on the corresponding error information. This is the end of the subroutine processing.

If it is determined in step E01 that the print mode is not the partial print mode, then step E
In 03, it is determined whether or not the mode is the protected statement print mode.
If it is the protected statement print mode, then go to step E
Proceed to 04, where the new value is initially set to "1" in the bank counter
Is set, the processing after step E05 is performed.

In step E05, it is determined whether the protect flag "1" is set in the corresponding bank of the management data memory 24a in the RAM 24 according to the count value of the bank counter. If it is set, this message data is a protect message, so at step E06, the message "Protect message" is first printed and then this message data is sent. The printer etc. are printed out by the printer 31 as in step E02, and the message No. of the display unit 29 and the call type display unit 29 are displayed.
No of the message data currently being printed in j, that is,
The count value of the bank counter and the call type information of the message data are displayed.

If the corresponding protect flag "1" in the message data is not set at step E05, the message data is protected.
Therefore, the processing of step E06 is not performed. After that, in step E08, the count value of the bank counter is updated and set to "+1", and in step E08, it is determined whether or not the updated and set count value exceeds the number of incoming data stored in the RAM 24.

If it is determined that the amount of time has not been exceeded, then the process returns to step E05. Thus, steps E05 to E
By repeatedly executing the processing of 08, the message data stored in the RAM 24 is searched in the order of the bank number, and the ones with the protect flag set are sequentially printed out together with the display of the bank number. .

When all the printouts of the message data with the protect flag set are completed, the update setting of the bank counter advances, and the count value exceeds the number of incoming data stored in the RAM 24, This is determined in step E09, and finally, the count value of the bank counter saved in step E09 is reset, and then the subroutine is ended.

If it is determined in step E03 that the print mode is not the protect text print mode, the print mode is the full text print mode. Then, after the initial value "1" is newly set in the bank counter, the processing after step E11 is performed. At step E11, the character "ALL MESSAGE" is first printed, then the message data etc. is read from the RAM 24 according to the count value of the bank counter, and this message data etc. is printed by the printer 31 as in step E02.
The message is printed out and the message N on the display 29 is displayed.
The count value of the bank counter and the call type information are displayed on the o and call type display portion 29j.

Then, in step E12, the count value of the bank counter is updated and set to "+1", and then in step E13.
Then, it is judged whether or not the updated set count value exceeds the number of message data stored in the RAM 24.

If it is determined that the number of times the vehicle has exceeded the limit, then the procedure returns to step E11. Thus, steps E11 to E
By repeatedly executing the processing in step 13, all the message data stored in the RAM 24 is printed out together with the display of the bank number in the order of the bank number.

When the printing out of the stored message data is completed and the count value of the bank counter exceeds the number of data stored in the RAM 24, this is judged in step E13, and finally the step After resetting the count value of the bank counter that was saved at E14, the subroutine is completed.

After the printing process according to the printing mode is executed as described above, the printing process is performed as shown in step D25 of FIG.
Set the 0 second timer and start. Then, in the following step D26, the message corresponding to the bank No. stored in step D23, that is, the initial message when the printing process is started, is displayed, and the series of processes is terminated, and the above-mentioned step is executed. Return to D04.

When the mode selection switch 18 is operated in the printout mode, the mode is switched as shown in step D11 and the printout mode is changed to the time adjustment mode. The operation in this time adjustment mode is merely the adjustment process of the current time data measured by the clock unit 23 and is not related to the present invention. Is shown in FIG.

When the mode selection switch 18 is operated in the time adjustment mode, the time adjustment mode is changed to the normal mode.
In the normal mode at this time, the message of the currently selected bank is displayed on the message display section 29a of the display section 29 as shown in FIG. 5 (F). This display state is the same as the display state at the time of the reading process in step A07 of FIG. When the mode selection switch 18 is operated in this normal mode, the mode is switched to the protect mode as shown in FIG.

Note that these modes can be switched even during the reading process of step A07, and the mode switching in this case is similar to the switching from the normal mode shown in FIG. 5 (F). Is.
