Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a selective call receiver with a display function used in an individual selective call wireless communication system.

[Prior Art and its Problems] In the individual selective calling radio communication system, a memory for storing a plurality of message information is provided, and at the time of calling, the received message information is displayed on the display unit and the received message is displayed. A selective call receiver with a display function is used in which information is stored in the memory and can be displayed again by a later switch operation. In this type of receiver, when the memory capacity becomes full, the message information stored in the memory is automatically deleted in the oldest order each time an incoming call arrives. Therefore, for a long period of time, There is a problem that even important message information that you want to keep is automatically deleted.

Therefore, recently, a receiver having a so-called message protection function has been developed in which the above message information is not automatically erased even when the message information becomes the oldest message information in the memory.

However, conventional receivers with message protection function
Since the message information to be protected or its management information is stored in a memory area different from the normal message information to be automatically deleted or its management information, there is a problem that the memory usage efficiency is low.

[Purpose of Invention] This invention was made in view of the above situation.
It is an object of the present invention to provide a selective call receiver with a display function, which has a message protection function and is efficient in memory usage.

[Points of Invention] In this invention, the message information stored in each corresponding message information storage means should be protected corresponding to each of the plurality of message information storage means for storing the received message information. Identification information storage means for storing identification information as to whether or not there is present is provided, and the automatic deletion of the message information is controlled based on the identification information stored in the identification information storage means. The required memory capacity is limited to 1 bit per message information storage means, and when a specific key for making the displayed message information protected message information is operated, the message information already protected If the number of messages is equal to the predetermined number, the message information storage means in which the message information being displayed is stored is displayed. Produced by providing prohibiting means for prohibiting storage of information indicating that the message information should be protected in the corresponding identification information storage means, and providing the identification information storage means in association with each message information storage means. This is to prevent an inconvenience to be obtained, that is, inconvenience that the message information stored in all the message storage means is protected message information and new incoming message information cannot be stored.

[Embodiment of the Invention] An embodiment of the invention will be described below with reference to the drawings.

First, FIG. 1 shows the circuit configuration. 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 wireless unit 12 performs intermittent reception by driving the decoder unit 13, and amplifies and demodulates a received radio wave and sends it to the decoder unit 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 the number called together with the call detection signal was,
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. CPU
Reference numeral 14 controls the operation of the entire other circuit according to a signal from the decoder unit 13 and an input signal from the switch input unit 15, and is composed of a ROM storing various control programs, a timer, an arithmetic register, and the like. .

A signal according to the operation is sent to the CPU 14. CP
U14 is connected to a clock unit 23 that performs a timekeeping operation and 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, while it is emitted to a speaker 26 via an amplifier 25. The sound signal is sent to the LED 28 through the amplifier 27 to notify the fact that there is a call. And CP
The U14 outputs display data such as message information and displays it on the display unit 29 composed of a liquid crystal display element, and also outputs print data to a printer 31 connected through the external terminal 30 and prints it out. .

When the main switch 16 is turned off, power supply to all circuits other than the CPU 14, the switch input section 15, the clock section 23 and the RAM 24 is stopped.

The display unit 29 has a display pattern as shown in FIG. 2, for example. In the same figure, in addition to the message display section 29a for displaying message information in alphanumeric characters, kana, hiragana and kanji, the display section 29 has a protect mode display 29b for notifying that the protect mode has been entered and a delete mode has been entered. A delete mode display 29c for notifying that the printout mode has been entered, a printout mode display 29d for indicating that the printout mode has been entered, a time adjustment mode display 29e for indicating that the time adjustment mode has been entered, and message information that has not been displayed at all Therefore, there is an unconfirmed (undisplayed) display 29f that informs that there is unconfirmed message information, a protect message display 29g that informs that the displayed message information has protected message information, and a power source. Low voltage indicator 29h, which indicates that the battery is exhausted Standing volume switch
22 A volume indicator 29i for notifying the position, a message No for displaying the message information NO displayed and the call type information and a call type display portion 29j are provided. The message display section 29a and the message N
o and the call type display section 29j are both formed of a dot matrix, the message display section 29a can display 12 characters × 2 lines in full-width characters, and the message No and call type display section 29j can display the same three characters. Become.

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

As shown in FIG. 3A, the management data memory 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 is not displayed yet, and the reset switch for instructing to stop the sound emission during the sound emission. A reset flag indicating whether or not 17 has been operated, information indicating the type of calling, a bank number indicating a storage area of message information in the message memory 24b, and a date and time when an incoming call is 1
A plurality of sets, for example, 30 sets of management data are stored in the management data memory 12a in a LIFO manner so as to be readable.

On the other hand, as shown in FIG. 3 (B), the message memory 24b
Is for storing a plurality of sets, for example, 30 sets in page management, by grouping the actually received message information with error information indicating which block of the message information has an error.

Here, the configuration of the selective call signal received by the antenna 11 and demodulated by the wireless unit 12 will be described. For example, the POCSAG system selective call signal, which has become an international standard,
It is composed of a header part for synchronizing bit by bit called a preamble and a data part called one or more N continuous batches. One batch includes a sync codeword and eight subsequent frames, and one frame includes 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), and the first bit is set to "0" and is 1
An address bit consisting of 1 bit, and a function bit of 2 bits and a parity bit of 11 bits are added to the address bit. The function bit is call type information added to the call number. Four kinds of calls called multi-address calls can be distinguished by this bit, and four different sounds and indications (symbol “A "Displayed by" D ").

On the other hand, the message codeword is a codeword for message information, and the first bit is set to "1".
It consists of a 1-bit message bit and 11 parity bits, 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 unit 13, amplifier 25, speaker 26, amplifier 27, LE
When the supply of power to D28 and the display unit 29 is started,
The CPU 14 starts the processing 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 CPU 14
An internal timer, a bank counter in the RAM 24, etc. are initialized. Next, in step A02, the input signal from the switch input unit 15 is read and the reset switch 17,
Mode selection switch 18, execution switch 19, memory bank switch 20, printing mode selection switch and volume switch
It is determined whether or not any one of 22 has been operated. afterwards,
In step A03, it is determined whether there is an incoming call. If it is determined that there is not, the process proceeds to step A04 and the above step A02.
It is determined whether or not the memory bank switch 20 has been operated according to the result of reading the operation switch. 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 again. That is, in the normal standby state, the processing of steps A02 to A05 is repeatedly executed at appropriate time intervals.

If it is determined in step A03 that there is an incoming call, the process proceeds to step A06 and the incoming call process is performed. This incoming call processing is received by the antenna 11 and demodulated by the wireless unit 12,
After confirming that the incoming data decoded by the decoder unit 13 and the time and date measured by the clock unit 23 at that time are not the second data by the repeat call transmitted within a predetermined time, for example, 60 seconds. Then, it is stored in the RAM 24. In this case, as the incoming data, the above-mentioned call type information, the message information indicating the message content when the message codeword is present, 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 obtained by shifting the incoming data stored in the management data memory 24a by one bank. The message is stored in the first bank together with the bank number of the message memory 24b storing the message. At the same time, the undisplayed flag “1” that is reset when a message is displayed in the reading process described later is set in the undisplayed flag register of the first bank, and the lighting control of the unconfirmed display body 29f is performed. The count value of the non-display flag counter used is incremented by "+1". At this time, if 30 sets of data have already been stored in the management data memory 24a, the older ones are sequentially erased by the shift process, but the undisplayed flag and the protect flag each have "1" data and "1" data. If the data of 0 "is mixed,
Data whose undisplayed flag and protect flag are “0”,
That is, the message information has been confirmed, the data is not protected, and the protect flag is "0".
Data, that is, the message information is unconfirmed, but unprotected data is deleted in this order in the shift process. Here, out of the 30 sets of data, the number of message data that can be protected by setting the protect flag to "1" is defined to be, for example, 20 sets. This is an inconvenience when all 30 sets of data can be protected, that is, the protect flag of all 30 sets of data is set to "1" and new incoming data cannot be stored, Alternatively, this is to prevent the inconvenience that most of the protected flags are set to “1” and the stored unprotected incoming data is automatically erased within a short time. 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 shift processing is performed in such a manner that the remaining 10 sets of old ones are sequentially deleted. After the storage in the RAM 24, the speaker 26 is driven through the amplifier 25 to indicate that there is a call, and the sounding (sound emission) is started. In this case, the ringing tone is different according to the call type information. 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 display is displayed.
Display processing corresponding to the incoming call, such as displaying the character "incoming call" at 29a, is started, and a timer for counting this display time is started. And the reset switch
If the display is displayed until 17 is operated or a predetermined time, for example, “8” seconds has elapsed, and the reset switch 17 is operated, or the time measured by the timer reaches a predetermined “8” second, 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 displaying processing is performed, and the incoming call data is stored in the RAM 24. The incoming data stored in the RAM 24 is read out in the subsequent step A07 when it is determined in step A04 in FIG. 3 that the memory bank switch 20 is operated.

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 mode is set by operating the memory bank switch 20 continuously for 2 seconds or more. There is a search data mode in which undisplayed incoming data among the incoming data stored in is searched and displayed. At the beginning of the processing, first, the timer for 2 seconds for measuring the operation time of the memory bank switch 20 in the CPU 14 and the timer for 30 seconds for measuring the display time of data are started, and the initial value "1" is set to the bank counter. After that, as a normal mode, the incoming data is read according to the count value of the bank counter, and the incoming data, that is, call type information,
The message information is displayed on the display unit 29 together with the information of the arrival date and time. Here, if the message information is undisplayed message information, that is, the flag "1" is set in the undisplayed flag register of the corresponding bank of the management data memory specified by the count value of the bank counter. If this occurs, this flag is reset, the count value of the non-display flag counter is set to "-1", and the message No. and call type symbol displayed on the display unit 29j are flushed. If the displayed message information is error message information, the display digit portion designated by the error information stored in the message memory 24b corresponding to this message information should be highlighted. Becomes After the data is displayed, the display is continued until 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 the 30 second timer and the 2 second timer expire. . When the 30-second timer times out, it means that the display for the predetermined time is finished, so that display is turned off, and if the search mode is set, the mode setting is also turned off. The process ends.

Also, when it is determined that the reset switch 17 has been operated during the display, the display is turned off and the mode setting of the search mode is turned off according to the operation of the reset switch 17, and the reading process is ended.

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

If the memory bank switch 20 is newly turned on during data display, the instruction is to prompt the display of incoming data of the next bank. Therefore, the undisplayed data search mode is reset and the 2-second timer After restarting the time counting operation of the 30 second timer, the count value of the bank counter is updated and set to "+1", and according to the count value, the next incoming data, that is, the incoming data immediately before the incoming data being displayed, is received. The received incoming data is displayed.

Thus, in the normal mode, each time the memory bank switch 20 is operated once, and in the search mode, only the undisplayed incoming data can be selected and displayed from the RAM 24.

The above shows the incoming call process and the reading process in the normal mode. When it is determined in step A05 in FIG. 4 that the mode selection switch 18 for instructing the mode change is operated, then step A08 is executed. Then, the process goes to the mode switching selection process. In this mode selection process, the count value of the mode counter provided in the RAM 24 is updated and set. The mode counter is composed of a quinary counter showing five mode states of a normal mode, a protect mode, a delete mode, a printout mode, and a time adjustment mode. The count value "0" indicates the normal mode, and the count value "1" indicates the count mode. The protect mode, the delete mode with the count value "2", the printout mode with the count value "3", and the time adjustment mode with the count value "4", respectively. Therefore, the count value of the mode counter in the normal mode is "0", and when the mode selection switch 18 is operated once to reach from step A05 to step 08 and the mode selection processing is performed, the count of the mode counter is counted. The value is updated and set to "+1" and becomes "1". Corresponding to the count value of the mode counter, the process corresponding to the mode selected in the subsequent step A09 is performed, and after the process, the process 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, all display bodies 29a to 29j are driven as shown in FIG. 5 (A) in order to avoid power consumption of the selective call receiver with a display function having a limited power capacity as much as possible. It has stopped. When the mode selection switch 18 is operated in such a state, this is determined in step A05, and then step A08 is reached. At step A08, the count value of the mode counter in the RAM 24 is updated and set to "1" from "0" to "1", and at the following step A09, the protect mode process shown in FIG. 6 is performed corresponding to this count value "1". Is performed.

In FIG. 6, first, as shown in step B01, the CPU 14 in which the minimum time for mode display, "8" seconds, is set.
Set the internal 8 second counter clock and start. Then, in step B02, the display section 29 displays that the mode has shifted to the protect mode. 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 29b is driven to light. Along with this, the call type information of the newest message information stored in the first 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 portion 29j, for example, 01C ”is displayed.

After that, in step B03, the timer for 8 seconds is timed up, in step B04 the reset switch 17 is operated, in step B05 the mode selection switch 18 is operated, and in step B06 the execution switch 19 is operated. It is continuously determined whether or not the memory bank switch 20 is operated in step B07. When it is determined to be NO in any of these, the process returns to step B03, and the operation input of the switch is awaited while repeating the processes of steps B03 to 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 switch operation is not performed even if the display of this protect mode is continued. Then, the process goes to step B08 to reset the contents of the mode counter to "0" and perform a reset process. In response to this, the display also changes from the display state of the protect mode shown in FIG. 5 (B) to the arrow TU.
As shown in FIG. 5, the normal mode standby state shown in FIG.

Also, when it is determined in step B04 that the reset switch 17 has been operated, in order to cancel the protect mode in accordance with the operation of the reset switch 17, the process proceeds to step B08 and the contents of the mode counter are reset in the same manner as above. The value is set to "0", and accordingly, the display also returns from the protected mode display state shown in FIG. 5 (B) to the normal mode standby state shown in FIG. 5 (A). To finish.

If it is determined in step B05 that the mode selection switch 18 has been operated, the count value of the mode counter is updated and set to "+1" in step B09 in response to the operation of this step, the mode is changed to the delete mode, and the display is displayed. After the display state shown in FIG. 5 (C) is reached, this processing ends.

If it is determined in step B07 that the memory bank switch 20 is operated, then the count value of the bank counter is updated and set to "+1" in step B10, and the count value updated and set in step B11 is stored in the RAM 24. It is determined whether the number of incoming data that has been exceeded is exceeded.
If it is judged that the time has not been exceeded, in the subsequent step B12, a 30-second timer for measuring the display time of the message information is set and started, and at the same time, in step B13, the corresponding message information, etc. Read incoming data and display 29
Is displayed on the message display unit 29a or the like. Thereafter, at step B03, this message display is continued until it is determined that the 30-second timer has timed up, or at steps 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, in which the initial value " 1 "
After setting, proceed 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 detected in step B06, and step B15 is detected.
And whether the protect flag "1" is set in the bank of the management data memory 24a currently designated by the bank counter, that is, whether or not the currently displayed message is a protected message. To judge. If it is determined in step B15 that they have not been set, the process proceeds to step B16. In 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 or not the number of protect flags set to is less than 20. If it is determined that the protection is possible, then the process proceeds to step B17, and after setting the protect flag “1” of the corresponding message information,
At step B18, the timer for 8 seconds is set and started, and at the same time, at step B19, a message indicating that the message has been protected is displayed on the message display section 29a of the display section 29 as a protection completion display. After that, the processing from step B03 is performed, and the protection completion display is continued until the 8-second timer times out.

In addition, protection is impossible in step B16,
That is, if it is determined that 20 sets of message information have already been protected, the process proceeds to step B20, and the timer for 8 seconds is also set and started. Is displayed on the message display portion 29a of, for example, "The protection capacity is full". After that, the processing from step B03 is performed, and the non-protection display is continued until the 8-second timer has timed up.

On the other hand, when it is determined in step B15 that the protect flag "1" is set, the process proceeds to step B22,
After resetting the protect flag, set 8 in Step B23.
At the same time as setting and starting the second timer, at step B24, the message "Protection has been released." Is displayed on the message display section 29a of the display section 29 as a protection release completion display. 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. In step B24, a protection release completion display is started. After this, the process returns to step B03, and the protection release completion display is continued until the 8-second timer times out or the switch operation is detected in steps B04 to B07.

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

In FIG. 7, first, as shown in step C01, the CPU 14 in which the minimum time for mode display, "8" seconds, is set.
Set the internal 8 second counter clock and start. Then, in step C02, the display unit 29 displays that the mode has shifted to the delete mode. in this case,
On the display unit 29, while the characters "Delete mode" are displayed on the message display unit 29a as shown in FIG. 5 (C),
The delete mode display 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 portion 29j, for example, "01C". And so on.

After that, in step C03, the timer for 8 seconds is timed up, in step C04 the reset switch 17 is operated, in step C05 the mode selection switch 18 is operated, and in step C06 the execution switch 19 is operated. It is continuously determined whether or not the memory bank switch 20 is operated in step C07. If NO in any of these steps, the process returns to step C03, and the operation input of the switch is awaited while repeating the processes of steps C03 to 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 switch operation is not performed even if the display of this delete mode is continued. Then, the process proceeds to step C08, and the mode reset processing such as resetting the content of the mode counter to "0" is performed. In response to this, the display also returns from the display mode in the delete mode shown in FIG. 5 (C) to the standby mode in the normal mode shown in FIG. 5 (A), and the process is completed.

Also, when it is determined in step C04 that the reset switch 17 has been operated, in order to cancel the delete mode in accordance with the operation of the reset switch 17, the process proceeds to step C08 as described above and the contents of the mode counter are reset. The value is set to "0", and accordingly, the display also returns from the display state of the delete mode shown in FIG. 5 (C) to the standby state of the normal mode shown in FIG. 5 (A). To finish.

When it is determined in step C05 that the mode selection switch 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 is converted to the printout mode and displayed. After making the display state shown in FIG. 5 (D), this processing ends.

If it is determined in step C07 that the memory bank switch 20 is operated, then in step C10 the RAM
It is determined whether or not the flag "1" is set in the processed flag register for display control in 24. If it is determined that it has been set, it means that the incoming data has already been deleted at the time before that, so the flow proceeds to step C11, and the incoming data stored in the management data memory 24a of the RAM 24 is received. The data is sorted, the number of stored incoming data is updated by "-1", and the processed flag register is reset to "0". If it is determined in step C10 that the processed slag "1" is not set, the process proceeds to step C12, and 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 judged that the time has not been exceeded, in the subsequent step C14, a 30-second timer for measuring the display time of the message information is set and started, and at the same time, in step C15, the corresponding message information from the RAM 24 is displayed in accordance with the count value of the bank counter. The incoming data is read out and displayed on the message display section 29a or the like of the display section 29. Then step C
This message display is continued until it is determined at 03 that the 30-second timer has timed up, or at steps C03 to C07 that each switch has been operated.
If it is determined in step C13 that the updated count value of the bank counter exceeds the number of incoming data stored in the RAM 24, the process proceeds to step C16 and the bank counter is reset to the initial value. After setting "1", the process proceeds to step C14.

When the memory bank switch 20 is operated to select and display the message information to be deleted as described above and the execution switch 19 for instructing the execution of the delete process is operated, this is determined in step C06, and the next step C17
Proceed to. In step C17, the erasing process of the designated message information in the management data memory 24a of the RAM 24 and the message memory 24b and other corresponding data is actually performed. After that, in step C18, the processed flag "1"
After setting, a timer for 30 seconds is set and started at step C19, and at the same time, at step C20, a message such as "The message has been erased." Is displayed on the message display section 29a of the display section 29 as a delete completion display. . After that, the processing from step B03 is performed, and the delete completion display is continued until the 30 second timer times out.

Then, as shown in step C09, the mode selection switch 18 is operated from the delete mode, the count value of the mode counter is updated and set to "3", and the printout mode processing after switching to the printout mode is performed. This will be described with reference to FIG. At this time, the printer 31 is surely connected to the external terminal 30.

In FIG. 8, first, as shown in step D01, the partial print mode, the protect sentence print mode, the full sentence print mode, and the partial print mode out of the three print modes, that is, printing for printing only the displayed message data is performed. Set the mode. At the same time, the flag "1" is set in the 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 stage of designing the printout mode. After that, in step D20, the clock of the 8-second counter inside the CPU 14 is set,
Start. Then, in step D03, the display unit 29 displays that the mode has shifted to the printout mode. In this case, in the display unit 29, as shown in FIG. 5 (D), the message "Display mode" is displayed on the message display unit 29a.
Display each of the two print mode characters. In this case, since "partial printing" is initially set as the print mode, only the characters "partial" are displayed in reverse video. Also, along with this, the printout mode indicator 29
d is turned on. Further, 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 out as the message number and the call type display portion 29j.
Is displayed, for example, "01C".

After that, in step D04, the timer for 8 seconds is timed up, in step D05 the reset switch 17 is operated, in step D06 the mode selection switch 18 is operated, and in step D07 the print mode selection switch 21 is operated. Whether or not it was operated, the execution switch in step D08
It is continuously determined whether or not 19 is operated, and whether or not the memory bank switch 20 is operated in step D09. If NO is determined in any of these, the process returns to step D04, and the operation input of the switch is awaited while repeating the processing of steps D04 to D09.

If it is determined in step D04 that the 8-second timer has timed out, the switch operation in this printout mode is not performed for 8 seconds, and similarly, if the display in this printout mode is continued, the switch operation is not performed. If not, then step D10
Then, the reset process is performed such as resetting the contents of the mode counter to "0". In response to this, the display returns from the display state of the printout mode shown in FIG. 5 (D) to the standby state of the normal mode of FIG. 5 (A), and this processing is ended.

Also, when it is determined in step D05 that the reset switch 17 has been operated, in order to release the printout mode in accordance with the operation of the reset switch 17, the process proceeds to step D10 and the contents of the mode counter are reset in the same manner as above. Then, the display is returned to the normal mode standby state of FIG. 5 (A) from the display state of the printout mode shown in FIG. 5 (D), as shown by the arrow TU. This process ends.

If it is determined in step C06 that the mode selection switch 18 has been operated, the count value of the mode counter is updated and set to "+1" in step C11 in response to the operation of this switch, and the mode is converted to the time adjustment mode and displayed. Is set to the state shown in FIG. 5 (E), and this processing is ended.

If it is determined in step C07 that the print mode selection switch 21 is operated, then in step C12 RA
It is determined whether or not the flag "1" is set in the initial state flag register of M24. If it is determined that the print mode selection switch 21 has not been set, it means that the execution switch 19 or the memory bank switch 20 has been operated after the flag "1" was set in step D01. Returning to the processing from step D04, if it is determined that it is set, then in step D13, the count value of the print mode counter is updated and set, and the partial print mode is changed to the protect text print mode.
A print mode switching process is performed from the protected text print mode to the full text print mode, or from the full text print mode to the partial print mode, and the character of the corresponding message display portion 29a is displayed in reverse video. After that, the process proceeds to step D14, and the display of the changed print mode is continued for a predetermined time 3
The 0 second timer is set and started, and then the processing from step D04 is started.

When the memory bank switch 20 is operated in order to select and print 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 partial print mode is not set, the operation of the memory bank switch 20 is invalidated, and the process returns to step D04. However, if it is determined that the partial print mode is set, the next step D16 is performed. Then, 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,
The updated count value of the bank counter is stored in the RAM.
It is determined whether the number of incoming data stored in 24 is exceeded. If it is determined that the time has not been exceeded, the timer for 30 seconds is set and started in the following step D18, and at the same time, the incoming data such as the corresponding message information is read from the RAM 24 in accordance with the count value of the bank counter in the step D19, and the display unit 29 Is displayed on the message display unit 29a or the like. Then, at step D04, it is judged that the 30-second timer has timed up, or step D04
This message display is continued until it is determined that each switch is operated in D09. The above step D17
If it is determined that the count value of the bank counter exceeds the number of incoming data stored in the RAM 24, the process goes to step D20 to set the bank counter to the initial value "1", Proceed to step D18.

Then, the execution switch 19 that is actually instructed to execute printing
When is operated, it is determined by this operation input that the execution switch 19 is on in step D08, and then step D21.
Proceed to. 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 stored in the internal register of the CPU 14 for temporary saving, and then the process proceeds to step D24 to execute the printing process.

FIG. 9 is a subroutine showing the details of this printing process. 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 number (bank number), call type information, presence / absence of a non-display flag, presence / absence of a protect flag,
The date and time of the incoming call, message information, and the like. If the message information is error message information,
Based on the corresponding error information, that portion is printed in black and white inversion as in the case of display. This is the end of this subroutine processing.

If it is determined in step E01 that the print mode is not the partial print mode, then it is determined in step E03 whether the print mode is the protect statement print mode. If the print mode is the protect text printing mode, the process proceeds to step E04, where the bank counter is newly set to the initial value "1", and the processes after step E05 are 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. Therefore, in the following step E06, the character "Protect message" is first printed, and then this message data is printed by the printer 31 as in step E02. Along with printing out, the message No. of the display unit 29 and the call type display unit 29
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, it means that the message data is not a protect message, so the process 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, the updated count value is stored in the RAM 24.
It is determined whether or not the number of incoming data stored in is exceeded. If it is determined that the amount has not been exceeded, then the process returns to step E05. By repeatedly executing the processing of steps E05 to E08 in this way, the message data stored in the RAM 24 are searched in the order of their bank numbers, and those having the protect flag set are sequentially bank numbers.
Will be printed out together with the display. When all the printout of the message data with the protect flag set is completed, the update setting of the bank counter proceeds, and the count value exceeds the number of incoming data stored in the RAM 24, this is determined in step E09, and the last After resetting the count value of the bank counter saved in step E09, the subroutine is completed.

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. In step E11, the characters "all messages" are first printed, then the message data and the like are read from the RAM 24 in accordance with the count value of the bank counter, and the message data and the like are read by the printer 31 as in step E02.
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. After that, in step E12, the count value of the bank counter is updated and set to "+1", and in step E13, it is determined whether or not the updated count value exceeds the number of message data stored in the RAM 24. If it is determined that the time has not been exceeded, then the process returns to step E11. By repeatedly executing the processing of steps E11 to E13 in this manner, the RAM
The message data stored in 24 is the bank number
According to the order of, the bank numbers are all displayed and printed out. When all the stored message data have been printed out and the count value of the bank counter exceeds the number of data stored in the RAM 24, this is determined in step E13, and finally the bank counter saved in step E14. After resetting the count value of, this is the end of this subroutine.

After the printing process according to the printing mode is executed as described above, the 30 second timer is set and started as shown in step D25 of FIG. Then, in the following step D26, the bank number stored in the above step D23.
The message corresponding to, that is, the initial message at the time of entering the printing process is displayed, the series of processes is terminated, and the process returns to step D04.

When the mode selection switch 18 is operated in the printout mode, the mode is switched as shown in step D11 to change from the printout mode to the time adjustment mode. The operation in this time adjustment mode is simply the clock section 23. Since it is only the adjustment process of the current time data to be clocked and has nothing to do with this proposal, its explanation is omitted and the display unit
Only the 29 display states are shown in FIG.

In the time adjustment mode, the mode selection switch 18
When is operated, the time adjustment mode changes to the normal mode,
In the normal mode at this time, as shown in FIG.
The message of the currently selected bank is displayed on the message display section 29a of the display section 29. This display state is the 4th
This is the same as the display state during the reading process in step A07 in the figure. When the mode selection switch 18 is operated in this normal mode, the mode is switched to the protect mode as shown in FIG. These modes can be switched 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).
