The display control on the LCD display 2 of the information communication apparatus of this embodiment will be described in detail below with reference to FIG. As an example of the display, a character code “ABC”, graphic data of “square” surrounded by diagonal lines and graphic data of “circle mark” indicated by a broken line and the character code “123” are overwritten on the LCD display 2. The case of displaying will be described. In this embodiment, the data to be displayed is stored in the VRAM 4 as a plurality of display front screens and one display back screen as shown in the figure.

First, when there is a display request as described above, the CP
U1 transfers the character codes of "ABC" and "123" and the graphic data of "square" and "circle" from the ROM 9 to the LCD controller 3 via the address bus and the data bus. In response to this, the LCD controller 3 obtains the dot patterns corresponding to the character codes “ABC” and “123” from the display CG 5, stores them in the display table screen 1 of the VRAM 4, and stores the “square” and “circle” marks. Graphic data is V
It is stored in the back screen 1 for display of the RAM 4. Then LCD
The controller 3 synthesizes the display front screen 1 and the display back screen 1 of the VRAM 4 and displays them on the LCD 2. VRAM
4 is managed on a plurality of screens in this way, for example, when only the "ABC" portion is changed to "XYZ", "ABC" and "123" are displayed on the display table screen 1 and the display table screen 2 is displayed. By storing "XYZ" and "123" in the display, it is possible to realize a high-speed display only by changing the display table screen 1 to the display table screen 2 and it is not necessary to rewrite the contents of the VRAM 4, so the display contents The display screen does not flicker when changing.

In this embodiment, the back screen for display is explained as one surface, but it goes without saying that a plurality of screens can be prepared in the VRAM 4 as this back screen for display.

Next, a detailed description will be given of how the change in the appearance and the state of the device on the LCD 2 in this embodiment is displayed in a graphic form.

FIG. 4 shows a method of storing the graphic data displayed on the LCD 2 in the ROM 9. In this embodiment,
The graphic data displayed on the LCD 2 is stored in the VRAM 4 by dividing the area of each graphic into two areas, that is, the left half and the right half. In order to make effective use of the storage capacity of the ROM 9, each of the two divided parts is divided into a part with a change in the appearance of the device and a common part without the change. The center of the main body is shifted to the right with respect to the center of the divided screen and stored. 4 (a) and 4 (b) corresponding to the appearance change on the left side of the apparatus, and FIGS. 4 (c), 4 (d), 4 (e) and 4 (e) corresponding to the appearance change on the right side of the apparatus. Four
By combining with (f), changes in the external appearance of the device as shown in the combination example of FIG. At this time, L
Since the CD controller 3 manages the figure data by dividing it into left and right parts, for example, when changing FIG. 4 (a) to FIG. 4 (b), the screen display can be changed at high speed simply by rewriting the left half. it can.

Here, the point that the LCD controller 3 synthesizes the divided graphic data to generate one device external view will be described in detail.

FIG. 5 is a schematic view of the storage contents of the VRAM 4, a portion of the storage contents displayed by the LCD 2 and a memory map showing that the graphic data of the external appearance of the device is stored in the portion displayed by the LCD 2.

In FIG. 5, 31 is a memory space of the VRAM 4, 32 is an LCD display portion displayed on the LCD 2 of the memory space 31, and 33 is an L level by the LCD controller 3.
Graphic data on the left side of the device appearance developed on the CD display portion 32, and 34 is graphic data on the right side of the device appearance developed on the LCD display portion 32 by the LCD controller 3.

As an example of the LCD controller 3 displaying an external view of the device on the LCD 2 based on FIG. 5, a case where the left data of the external appearance of the device is displayed and then the right data is displayed will be described. The VRAM 4 used in this embodiment is shown in FIG.
As shown in (4), each line is configured to have 40 bytes per line. The left and right graphic data of the external appearance of the device shown in FIG. 4 each have a size of 8 bytes in the horizontal direction.

Here, the VRAM to be displayed by the CPU 1 on the LCD 2 so as to represent the appearance of the left side of the device.
4 address to the LCD controller 3,
The LCD controller 3 acquires the dot pattern of the designated graphic data from the ROM 9 and transfers the dot pattern to the designated address of the VRAM 4. At this time, as described above, the VRAM 4 is 40 bytes per line in the horizontal direction, and the left and right graphic data of the external appearance of the device has a size of 8 bytes in the horizontal direction, respectively.
It is stored in. As a result, every time 8 bytes of the figure data representing the left side appearance of the device is transferred from the specified address, the LCD controller 3 transfers the address to be transferred next to the start address which has been transferred by 8 bytes 40 times. By setting the address to which the byte is added, the horizontal start addresses are always matched, so that the divided graphic data can be easily transferred to the VRAM 4.
Also when transferring the data showing the right side appearance of the device, the graphic data designated by the same process is changed by changing the graphic data to be displayed and the address to be displayed.
It can be easily transferred to M4.

In this embodiment, the back screen for display is explained as one screen. However, a plurality of back screens for display are prepared and the graphic data divided into the left and right are stored in different screens. Whenever you change the displayed content with
LCD screen to display the contents of AM4 without rewriting
It goes without saying that the figure to be displayed can be changed at high speed simply by selecting it by the controller 3. Further, it is needless to say that the number of divisions of the graphic data is not limited to two on the left and right, and may be further divided into a plurality of graphics and stored if there are many common portions. Also at this time, the storage capacity of the ROM 9 is effectively utilized by considering the position of the display figure with respect to the display area so that each figure to be divided is divided into a part with appearance change of the device and a common part without it. it can.

The operation of the information communication apparatus of this embodiment constructed as above will be described in detail below.

FIG. 6 to FIG. 8 show operation flow charts of the information communication apparatus of this embodiment. FIG. 6 is an operation flow chart from power-on to waiting for instructions for various operations.

7 and 8 are operation flow charts when a memory card is inserted in the apparatus, and FIG. 8 is a continuation of FIG.

A detailed description will be given below with reference to FIGS. 6 to 8. When the power switch of the device is turned on, the input / output circuit is initialized (step 1 (hereinafter abbreviated as ST1)). Next, the CPU 1 checks a memory card interface (hereinafter abbreviated as IF) to see if a memory card is inserted, and sets a confirmation flag as an index of the presence or absence of the memory card (ST2). This check operation will be described later together with the control for inserting / removing the memory card, and here, the CPU 1 executes only different processing depending on the presence / absence of the memory card.

When a memory card is inserted, CP
U1 transfers its control to a card processing routine described later (ST3).

The case where the memory card is not inserted will be described below. 10 to 12 show initial screens of the LCD 2. FIG. 10 is an initial screen of the LCD 2 when no memory card is inserted, and FIGS. 11 and 12 are initial screens of the LCD 2 when a memory card is inserted.

When the CPU 1 determines in ST3 that there is no card, the contents of the VRAM 4 for displaying the LCD 2 are initialized (S
T4), as shown in FIG. 3, the LCD controller 3 is displayed on the back screen 1 of the VRAM 4 as shown in FIG. 4A which is the left half of the figure data divided and stored in the ROM 9 as shown in FIG. It is transferred and displayed (ST5), and further, the right half of this screen, FIG. 4 (c), is transferred to the display back screen 1 of the VRAM 4 as shown in FIG. 3 (ST6), FIG. 4 (a), Figure 4 (c)
The graphic state of the combined device is displayed on the LCD 2. At this time, prepare multiple back screens for display, and
By storing (a) and (c) in different back screens for display and combining and displaying, it is possible to eliminate the need to rewrite VRAM4 when changing (a) to (b) in FIG. Of course you can. Next, the CPU 1 combines the function frame from the ROM 9 with the display back screen 1 in the VRAM 4 via the LCD controller 3 (ST7). At this time, FIG.
By displaying the function frame with a solid line and a dotted line as shown in, the three-dimensional function display is realized while eliminating the need for a plurality of rows and columns for display. That is, conventionally, when a stereoscopic display is performed on a two-dimensional screen, it is common to display a thick line to represent the front and a thin line to represent the rear. In order to display a thick line, it is necessary to use at least dots adjacent to each other vertically or horizontally. In the present embodiment, by displaying this frame with a solid line and a dotted line, a three-dimensional display with good visibility is realized even when there is no margin in the dots that are vertically or horizontally adjacent to each other. Also, FIG.
When a plurality of function displays are adjacent to each other as shown in FIG. 1, the dotted lines of the adjacent function frames are displayed as if showing the height of the solid line beside them.

Next, the CPU 1 which has displayed the function frame in ST7 displays the function character to be displayed in this function frame on the LCD controller 3 and the display C.
The back screen 1 for display in the VRAM 4 is combined and displayed via G5 (ST8).

Thereafter, the CPU 1 waits for various state changes of the apparatus by checking a state flag (not shown) (ST9). Here, the various status changes are hook-off / monitor-on, document set, incoming call, and external telephone use. Below, hook-off / monitor-on is the first mode, original set is the second mode, incoming call is the third mode, and external telephone is used. Will be described as a fourth mode.

The information communication apparatus of the present embodiment changes the display position of the graphic display of the external appearance of the apparatus as shown in FIG.

Before describing each mode, the display on the LCD 2 when the state of the device is not changed in ST9 will be described.

First, when the CPU 1 detects that there is no change in the state of the device in ST 9 (ST 10), it continuously monitors the change in the state of the device and starts timer processing at regular intervals (ST 11).

The timer process will be described in detail below. In C where it is judged in ST11 that a certain time has passed
The PU 1 calculates the next position from the display position data of the figure of the appearance of the device currently displayed on the LCD 2 and stores it in the RAM 8 (ST12). After that, the CPU 1 erases the graphic data of the external appearance of the device which is currently displayed (FIG. 4A and FIG. 4C) (ST13), and moves the graphic data of the external appearance of the device to the next position calculated in ST12 (FIG. 4A). And FIG. 4 (c) is transferred and displayed (S
(T14), and then the first timer processing ends. Here, details of the specific processing for moving and displaying the graphic data of the appearance of the device to be displayed will be described later. In the information communication apparatus of the present embodiment, the fixed time for the timer processing is set to 2 seconds so that the external appearance of the apparatus changes its position every 2 seconds during standby as shown in FIG. It is displayed as if wandering inside the LCD. still,
In addition to calculating the display position in ST12 to ST14 and moving the graphic data, a plurality of destination positions are stored in advance, and the display screen is stored in the VRAM 4 as shown in FIG. It goes without saying that this display can also be realized by preparing three images for variable position images. By changing the display on standby in this way, not only the standby display is interesting, but also the user can easily see that the device is operating normally.

Next, a case where the state of the apparatus is changed in ST9 will be described. In ST9, a change in the state of the device was detected C
PU1 (ST10) transfers the control to the processing routine for each state change shown in FIG. 7 (ST15).

The processing routine for each state change will be described in detail below with reference to FIG.

First, the first mode will be described. FIG. 13 shows the display of the LCD 2 when the handset is picked up to make a call or the monitor button is pressed down.

When the handset is picked up or the monitor button is pushed down (ST16), the CPU 1 rewrites the graphic data FIG. 4 (a) stored in the VRAM 4 into FIG. 4 (b) and displays it (ST17). Then, the dialing number of the destination to be dialed by the user with the ten keys 27 is displayed on the LCD 2 (S
T18). The display screen of LCD 2 displayed at this time is shown in FIG.
As described in detail in step ST17, the graphic data displayed in step ST17 is displayed in the back screen 1 for display in the VRAM4.
The character data of the destination number displayed by 18 is stored in the display table screen 1, and the respective screens are synthesized by the LCD controller 3 and displayed on the LCD 2 as one display screen.

FIG. 14 shows the display screen of the LCD 2 when there is a response from the other party after ST18.

In FIG. 14, 35 is a response icon, 3
6 is an icon during a call. After ST18, when there is a response from the other party, the CPU 1 displays the response icon 35 (S
At the same time as T19), the talking icon 36 and the talking time are displayed (ST20). In the present embodiment, the response icon 35 additionally displayed in ST19 and the talking icon 36 additionally displayed in ST20 are already registered in the ROM 9 as character codes, which is different from the method of displaying left and right divided figures. The CPU 1 designates a character code, and the LCD controller 3 synthesizes and displays the bit pattern output by the display CG 5 on the left-right synthesized graphic data. This display is stored in the display table screen 1 in the VRAM 4. As a result, the response icon 35 and the talking icon 36 can be handled as a character code. Therefore, the LCD controller 3 can display the character code simply and at high speed simply by designating where on the LCD 2 the character code is displayed. By simply adding the graphic data, the graphic mode can be displayed as if the graphic data was changed without changing the graphic data.

Then, when the call ends, the CPU 1 detects this and instructs the NCU 19 to disconnect the line (ST21).
The initial screen shown in FIGS. 10 to 12 is returned to prepare for the next state change.

Next, the second mode will be described. FIG. 15 shows a display screen of the LCD 2 when a document is set for fax transmission or copying while waiting for a state change (ST9).

When the original is set, the CPU 1 does not know at this stage whether the set original is for copying or for FAX transmission. Therefore, as shown in FIG. 15, it is necessary for copying and FAX transmission. Display all functions.

A detailed description will be given below with reference to FIG. F
When an original is set for AX transmission or copying (ST22), the CPU 1 rewrites the graphic data FIG. 4 (c) stored in the VRAM 4 into FIG. 4 (d) and displays it (ST).
23). Then, the function frame is additionally displayed (ST2
After 4), the characters displayed in this function frame are rewritten (ST25). The display screen of the LCD 2 displayed at this time is, as described in detail with reference to FIG. 3, the image data of the function frame displayed in ST24 in the VRAM 4 in the back screen 1 for display and in the function frame displayed in ST25. The character data of the characters to be displayed is stored in the display table screen 1, and the respective screens are additionally combined by the LCD controller 3 and displayed on the LCD 2 as one display screen. As a result, even if there is no character data width for one character below the displayed character data, the displayed character data can be surrounded by a frame, impairing the display area. It is possible to realize a display that is easy to see.

Reference numeral 37 in FIG. 15 denotes an electronic telephone directory icon representing an electronic telephone directory. This electronic telephone directory icon 37 has already been registered in the ROM 9 as a character code, and this display is a display table in the VRAM 4. It is stored in screen 1. By graphically displaying the function display in this way, the user can easily understand the display regarding the function selection of the device. Also, this electronic phonebook icon 37
Indicates not a size of one character but a combination of two characters. Needless to say, it is not necessary to limit the division of the character to two. Further, similarly to the above, all the graphic data displayed in the function frame such as the stamp is already registered in the ROM 9 as the character code. As a result, the CPU 1 can handle not only the character data but also the graphic data registered in the ROM 9 on a character-by-character basis, and a large graphic such as that displayed as image data can be displayed at high speed by combining character codes. . Here, the character code for displaying a figure by combining a plurality of characters is provided with a blank of at least one line dot in the vertical dot image so as not to overlap the characters displayed in the preceding and succeeding lines even when the line spacing is displayed. At the same time, a dot pattern is created in the horizontal dot image without providing a blank so as to display a figure in which a plurality of characters are continuous.

Then, the CPU 1 monitors whether or not the copy button of the operation key 28 has been pressed (ST2).
6).

The display screen of the LCD 2 during copying is shown in FIG. When the copy button of the operation key 28 is pushed down, the CPU 1 starts the copy operation under the function setting shown in FIG. 15 (ST27) and the VRAM.
The graphic data shown in FIG. 4 (d) is rewritten into the graphic data shown in FIG. 4 (e) and displayed (ST28). At this time, the graphic data of the appearance of the device displayed on the LCD 2 is synthesized and stored in the VRAM 4 on the display back screen 1 by the LCD controller 3 as described in detail with reference to FIG. Further, the CPU 1 activates the serial number counter to display "copying" next to the graphic data of the external appearance of the apparatus and also displays the number of copies on the recording paper portion of the graphic data of the external appearance of the apparatus (ST29). As a result, the user can immediately grasp the current operation mode and its progress by only looking at the graphic display of the appearance of the device displayed on the LCD 2. The character data of the number of copies displayed on the LCD 2 is displayed on the display table screen 1 in the VRAM 4 as described in detail with reference to FIG.
It is synthesized by the CD controller 3 and stored. Then, the CPU 1 deletes the function display unrelated to the copy operation from the LCD 2 (ST30). In this way, the function display unrelated to the operation being executed is displayed on the LCD 2.
By deleting from above, even a user who is unfamiliar with the operation of the apparatus will not be confused by the operation, and the mode being executed and the progress status thereof can be intuitively grasped.

When the copying of all originals is completed, the CPU 1 detects this (ST31) and returns to the initial screen shown in FIGS. 10 to 12 to prepare for the next state change.

Needless to say, the copying operation is performed in this changed mode even after the mode is changed by the function switches F1 to F4 described below.

Next, the display and processing operations of the LCD 2 in the case where an operation other than copying is performed after the document is set will be described.

First, the function switches F1 to F
The mode change by 4 will be described. Here, in the function switches F1 to F4, F1 is the light and shade of the original, F2 is the character size, F3 is the halftone, and F is the halftone.
4 corresponds to a stamp and F5 corresponds to an electronic telephone directory.

When the original is set, the display on the apparatus is as shown in FIG. 15 as described above. Here, the CPU1 which detects that the function switches F1 to F4 are pushed down
(ST32) changes the function content corresponding to the pressed function switch in the function display shown in FIG. 15 and rewrites the display content on the LCD 2 (ST33).

Next, as to the case where the original is set and the FAX transmission is performed, the case where the transmission destination is selected from the destination list registered in the electronic telephone directory and the FAX transmission is performed,
The case where the dial number of the other party is directly input from the ten key 27 and the FAX transmission is performed will be described separately.

First, the display on the LCD 2 in the case of FAX transmission from the electronic telephone directory will be described with reference to FIGS. 17 to 19. Here, FIG. 17 shows the display screen of the LCD 2 when the electronic telephone directory is opened, and FIG. 18 shows the FAX from the electronic telephone directory.
FIG. 19 shows the display screen of the LCD 2 during transmission dialing, and FIG. 19 shows the display screen of the LCD 2 during FAX transmission from the electronic telephone directory.

First, when the function switch F5 is pressed down after setting the original (ST34), the display of the LCD 2 is switched from the original setting screen shown in FIG. 15 to the electronic telephone directory screen as shown in FIG. 17 (ST35). At this time, as is clear from FIG. 15 and FIG. 17, in FIG. 15, the graphic data and the character characters are vertically combined so that the contents corresponding to the respective functions in the standby state fit within the function frame, and are displayed in an easy-to-understand manner. While doing
When the electronic telephone directory is opened, as shown in FIG. 17, the graphic data and the character are recombined in the horizontal direction so as not to damage the display range of the LCD 2, and the electronic telephone directory mode is displayed. As mentioned above, the electronic phonebook icon 3
6 has already been registered in the ROM 9 as a character code. As a result, the external view of the electronic telephone directory can be handled as a character code. Therefore, the LCD controller 3 can be displayed easily and at high speed simply by designating where the character code is displayed on the LCD 2 when changing the layout in the vertical and horizontal directions. It is possible.

Next, when the dialing destination is selected from the group of destinations registered in the electronic telephone directory shown in FIG. 17 with the scroll button 26 or the ten key 27 (ST36), C
PU1 automatically calls this dialed number (ST3
7).

After that, when the other party responds, the CPU 1 starts the transmission operation (ST38) and sets the ID coming from the other party to L.
Graphic data shown on CD2 (ST39)
By rewriting (d) to FIG. 4 (e) (ST40), the unnecessary function display of the electronic telephone directory is deleted (ST41),
Further, the communication counter for counting the number of transmitted sheets is activated to display the number of transmitted sheets (ST42). Here, the serial number counter shown in FIG. 19 displays the number part for counting the actual number of originals and the kanji part of the “sheet”.
The kanji part of "sheet" is always the same display during the transmission operation, and it is not necessary to link it with the serial number counter. For the above reason, in the present embodiment, the Chinese character portion of the "sheet" is registered as image data in the graphic data FIG. 4 (e) to increase the processing speed of the communication counter. After that, when the transmission of all originals is completed, the CPU 1 detects this (ST43).
The initial screen shown in FIGS. 10 to 12 is returned to prepare for the next state change.

Next, the display of the LCD 2 in the case of directly inputting the dialed number of the other party from the ten-key pad 27 and transmitting the FAX will be described. Fax transmission is performed by hooking off the receiver or pressing the monitor button after setting the original.

FIG. 20 shows the display on the LCD 2 when the receiver is hooked off after setting the original, and FIG. 21 shows the display on the LCD 2 when the monitor button is pressed down after the original is set.

In FIG. 21, reference numeral 38 is a dial tone icon for displaying the detection of dial tone.

After the user sets the original and hooks off the receiver for FAX transmission (ST44), the CPU 1
Displays the graphic data shown in FIG. 4 (a) by rewriting it into FIG. 4 (b) (ST45).

When the mode is set by the function switches F1 to F4 described above and the handset is hooked off for FAX transmission, the CPU 1 displays the character character of "dial" indicating that it is waiting for the input of the dial number and moves the cursor. Make it blink.

After that, when the dial number of the other party is input from the ten keys 27, the CPU 1 displays the input dial number on the LCD 2 (ST46). Needless to say, at this time, the user can make a telephone call and then continue FAX transmission. When the monitor button is pressed down instead of hooking off the handset (ST47), the CPU 1 additionally displays the dial tone icon 38 on the display of the LCD 2 (ST48) and indicates "waiting for dial number". Display the character and blink the cursor. After that, it is similar to the case of hooking off. When the dial number of the destination is input from the ten keys 27, the CPU 1 displays the input dial number on the LCD 2 (ST4).
6). When the other party answers the call, the FAX transmission is started on the display of the LCD 2 as shown in FIG.
The PU1 executes ST38 to ST43 similarly to the FAX transmission when making a call from the electronic telephone directory, and when the transmission of all the originals is completed, the CPU1 detects this (ST43).
0 to 12 to return to the initial screen to prepare for the next state change. Here, if the transmission mode is changed during FAX transmission, the LCD 2 displays as shown in FIG. That is, if the function switches F1 to F3 are pressed down during the fax transmission during the fax transmission, the setting changed here from the next document being currently transmitted becomes effective, and F4
When is pressed, the setting changed here from the original document currently being sent becomes valid. This is because in each of the modes F1 to F3, the information is transmitted prior to the image information of the document to be transmitted, whereas the completed stamp of F4 is pressed only after the document is transmitted, and is currently being transmitted. This is because there is no problem even if the manuscript is valid. As a result, it is difficult to know from which page the setting is effective when the transmission mode is changed in the related art, and it becomes possible to easily know the setting information for each document only by looking at the LCD 2.

In the case of directly inputting the dialed number of the destination from the ten-key pad 27 and transmitting the data by fax, there is no destination information registered in advance like the electronic telephone directory.
The display of D2 is the display shown in FIG. 22 during the FAX transmission operation as described above.

Next, the third mode will be described. First, a case will be described in which a call is received during standby on the initial screen shown in FIGS.

When a call is received while waiting on the initial screen, the display on the LCD 2 is as shown in FIG.

In FIG. 24, reference numeral 39 is a calling icon indicating that an incoming signal is detected. When a call comes in, an incoming signal of 16HZ arrives at NCU 19 (ST4
9). In the case of a telephone, unlike the FAX, the called identification signal is not detected (ST50), so the CPU that detected the incoming signal
1 additionally displays a calling icon on the LCD 2 (ST
51). In this embodiment, the calling icon additionally displayed in ST51 is already stored in the ROM as the character code.
9 has been registered, and this display is stored in the display table screen 1 in the VRAM 4.

FIG. 25 shows a display screen of the LCD 2 when the user receives the incoming call and picks up the handset for a call.

When the user picks up the receiver and hooks off, the CPU 1 rewrites the graphic data shown in FIG. 4A into FIG. 4B and additionally displays the response icon 35 (ST5).
2). In this embodiment, the response icon 35 additionally displayed in ST52 is already in the ROM as the character code.
9 has been registered, and this display is stored in the display table screen 1 in the VRAM 4. The graphic data rewritten in ST52 is stored in the display back screen 1 in the VRAM 4 as described above.

After that, when the call ends, C which detects this
The PU 1 instructs the NCU 19 to disconnect the line (ST53), returns to the initial screen shown in FIGS. 10 to 12, and prepares for the next state change.

Next, a case will be described in which a fax is received during standby on the initial screen shown in FIGS.

FIG. 2 shows the display screen of LCD 2 during FAX reception.
6 shows. When receiving an incoming fax, the incoming signal of 16HZ arrives at the NCU 19 (ST49). This incoming signal is the same as that of a telephone, but the device is set to FAX reception by a known technique in advance, or the 16HZ incoming signal is detected by the automatic reception mode, and after hooking off automatically, from the other party. It is possible to determine the incoming call of each of the telephone / FAX by calling the FAX when the transmitted call identification signal is detected, and by calling the telephone if this is not detected.

C when the callee identification signal is detected (ST50)
PU1 starts FAX reception operation (ST54), and LCD
2) Graphic data on 2) Display Fig. 4 (c) by rewriting it to Fig. 4 (f) (ST55) and activate the communication counter to display "Fax receiving" next to the graphic data of the external appearance of the device. The number of received sheets is displayed on the recording paper portion of the graphic data of. Further, the CPU 1 also synthesizes and displays the ID information sent from the other party on this display screen (ST56). At this time, the number of received sheets displayed on the LCD 2, the character "Fax receiving" and the character data of the ID information sent from the other party are the VRAM 4 as described in detail with reference to FIG.
Among them, the display table screen 1 is combined and stored by the LCD controller 3. Further, the graphic data of the appearance of the device displayed on the LCD 2 is stored in the VRAM 4 by being combined with the display back screen 1 by the LCD controller 3.

After that, when the communication is completed (ST57), the CPU 1 which has detected this command instructs the NCU 19 to disconnect the line (S
T58), returning to the initial screen shown in FIGS. 10 to 12 to prepare for the next state change.

Next, the fourth mode will be described. First, the case of using a telephone connected to the outside during standby in the initial screen shown in FIGS. 10 to 12 will be described.

FIG. 27 shows a display screen of the LCD 2 when the telephone connected to the outside is used.

In FIG. 27, reference numeral 40 denotes a slave unit in-use icon indicating that the slave unit is in use. When the telephone connected to the outside is used (ST59), the CPU 1 which has detected this additionally displays the child device in-use icon 40 and the character character of "child device in use" as shown in FIG. 27 (ST6).
0). In this embodiment, the child device in-use icon additionally displayed in ST60 is already RO as the character code.
It is already registered in M9, and this display is stored in the display table screen 1 in the VRAM 4. In this way, the child device in-use icon 4 registered with another character code that displays the current operation mode as a character character, “child device in use” is displayed.
By displaying together with 0, it is possible to realize the display as if the change of the operation mode is displayed by combining with the graphic image even though the change of the operation mode is displayed only by the character code. In the case where the display area is limited, the user can be notified of the change of the operation mode only by displaying the child device busy icon 40. Further, the character character "in use of child device" is stored in the display table screen 1 as described in detail with reference to FIG.

FIG. 28 shows the display screen of the LCD 2 when the telephone connected to the outside is being called.

In FIG. 28, reference numeral 41 denotes a slave unit calling icon indicating that the slave unit is being called. When the externally connected telephone is called from the main body of the apparatus, the CPU 1 displays the above-mentioned child device in-use icon 40 indicating that the child device is in use and the character character of "child device in use" on the LCD 2, as shown in FIG. Instead, the child device calling icon 41 indicating that the child device is being called and the character character of "child device calling" are displayed. Further, since the cordless handset call icon 41 and the cordless handset use icon 40 can be handled as character codes as described above, it is possible to easily move the display of the LCD 2 by alternately displaying the character codes. You can

When the F1 key corresponding to the menu mode is depressed during standby on the initial screen shown in FIGS. 10 to 12, electronic telephone directory registration, user registration such as ID information change / registration, list printing, and polling are performed. A main menu screen for executing reception, switching to a card program, etc. is displayed, and the electronic telephone directory is displayed when the F5 key is pressed to correspond to the electronic telephone directory mode.

The operation of the information communication apparatus of this embodiment has been described above, omitting the details of the specific processing of transferring / displaying the apparatus appearance graphic data to the LCD 2 and the memory card processing.

Now, a concrete process of transferring / displaying graphic data to the LCD 2 and a memory card process will be described in detail.

FIG. 9 shows a subroutine relating to specific processing for transferring / displaying graphic data. This subroutine is a detailed process of the part shown as "transfer and display graphic data" or "rewrite and display graphic data" in FIGS.

The transfer and display of the graphic data of the external appearance of the apparatus in this embodiment will be described in detail below with reference to FIG.
Here, the case where FIG. 4A is displayed as graphic data will be described.

First, when the CPU 1 designates the display of FIG. 4 (a), the LCD controller 3 receiving the designation acquires the address of the ROM 9 storing FIG. 4 (a) (ST1
00). Here, the ROM 9 stores the compressed graphic data of FIGS. 4A to 4F, which are graphic data representing the external appearance of the apparatus, separately from the addresses where the compressed graphic data are actually stored. Of the ROM 9 in association with which address of the ROM 9 the data starts, and a compressed data storage unit which stores each of the actual compressed graphic data corresponding thereto.

Next, the CPU 1 restores the compressed data of FIG. 4A, which is the graphic data corresponding to the address acquired in ST100, to the dot image actually displayed on the LCD 2 in units of 8 bytes (ST101). ).

The CPU 1 sets the start address of the transfer destination of the restored dot image on the VRAM 4 in the LCD controller 3 (ST102). The start address of the transfer destination set at this time indicates where on the LCD 2 the top data in FIG. 4A is to be displayed. However, in the present embodiment, 8
Since the transfer is instructed in byte units, it is necessary to instruct the transfer destination to transfer the next 8 bytes after transferring 8 bytes. Therefore, in this embodiment, in order to determine the transfer destination address for actually transferring the 8-byte unit data, ST10
The start address of the transfer destination specified in 2 is added to the address obtained by multiplying the number of loops with the first loop as 0 by 40 bytes to obtain the actual transfer destination address (ST
103). Then, the designated graphic data is transferred to the VRAM in units of 8 bytes at the address to be actually transferred.
4 (ST104). After that, ST101 to ST1 until all the data in FIG. 4A is transferred to the VRAM4.
The data transfer process 04 is repeated (ST105), and FIG.
When the transfer of all the data in (a) is completed, the processing of the subroutine is ended and the process returns to the respective steps of FIGS.

In the present embodiment, it has already been described that the graphic data of the external appearance of the device is moved and displayed when the device is in the standby state, but at this time as well, by transferring the white data as the graphic data to be rewritten, It goes without saying that the currently displayed graphic data can be erased from that position.

The above is the detailed description of the graphic data display of the appearance of the apparatus in this embodiment.

Next, the memory card insertion / removal control of the information communication apparatus of this embodiment will be described in detail.

FIG. 29 shows a schematic structure of the memory card insertion / removal control of the information communication apparatus of this embodiment.

In FIG. 29, reference numeral 42 denotes a reset I for resetting the CPU 1 when the card is removed from the connector 11.
C and 43 are switching transistors that supply power to the memory card 12, and 44 is the memory card 12 and the CPU 1.
A buffer for connecting a bus between the CPU 1 and the card 12, 45 is a check digit (hereinafter abbreviated as CD) on the left and right of the card pin for checking the presence / absence of the address bus signal and the data bus signal between the CPU 1 and the card 12, and the memory card 12. 1 and C
A card insertion signal generated by ORing with D2 is input, a power supply enable signal for the memory card is output to the switching transistor 43, and a bus connection enable signal for bus connection is output to the gate of the buffer 44, which will be described later. A parallel peripheral interface (hereinafter abbreviated as PPI) that outputs a reset enable signal for reset enable, 46 inputs a reset enable signal generated by ANDing a power supply enable signal output by the PPI 45, a bus connection enable signal, and a reset enable signal Then, the card insertion signal generated from the OR of CD1 and CD2 is set to NO with the reset IC 42.
It is a flip-flop input to the R circuit.

In FIG. 29, the same components as those in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted. Hereinafter, the memory card insertion / removal control of the information communication device according to the present embodiment will be described in detail with reference to FIG.

First, when the memory card 12 is inserted into the connector 11 of the main body, the CD1 and the CD on both ends of the connection pin are
2 is grounded in card 12, so CD1 and C
Both D2 output a low level. As a result, the card insertion signal generated from the OR of CD1 and CD2 is output at a low level. Next, the PP that received this card insertion signal
I45 outputs a high-level power supply enable signal to the switching transistor 43 and a high-level bus connection enable signal to the buffer 44, and an AND circuit which receives the AND output of the power supply enable signal and the bus connection enable signal as an input. A high level reset enable signal is output to one of the inputs. This A
The output of the ND circuit is a reset enable signal for the memory card 12. This reset enable signal is connected to the clear side of the flip-flop 46, and the flip-flop 46 resets the low level card insertion signal while the program by the memory card 12 is operating.
The output signal of 42 is output to the other input of the NOR circuit having one input. As a result, in the NOR circuit, either the flip-flop 46 or the reset IC 42 becomes the CPU.
When a high level for resetting 1 is input, a low level reset signal is output to the CPU 1.

Next, the case where the CPU 1 is reset in such a configuration will be described. First, the reset IC
A case in which 42 generates a reset signal due to power failure or the like will be described. When the voltage supplied to the device drops due to power failure or the like, the reset IC 42 generates a reset signal when the voltage drops to a certain level within a range where the CPU 1 does not malfunction. As a result, the CPU 1 can end its operation without causing a malfunction due to the voltage drop. This reset signal is a NOR provided in the preceding stage of the reset signal terminal of the CPU 1.
Since it is input to the circuit, the CPU 1 is reset and controlled regardless of the presence or absence of the memory card 12.

Next, the reset control by removing the memory card 12 during the program operation of the memory card will be described. When the main body side connector 11 and the left and right pins CD1 or CD2 of the connector 121 of the memory card 12 become ungrounded, that is, at a high level due to the memory card 12 being pulled out or skewed, the card insertion signal is flip-flop 46. Is input to the NOR circuit provided in the preceding stage of the reset signal terminal of the CPU 1. This gives N
The OR circuit outputs a low level to the reset terminal of the CPU 1, and the CPU 1 is reset without causing a malfunction due to card removal. If the memory card 12 is inserted but the program in the card is not executed, the reset enable signal is not input to the clear side of the flip-flop 46, so the card is removed and the card insertion signal becomes high level. However, it is not input to the NOR circuit provided before the reset signal terminal of the CPU 1
U1 is never reset.

The above is a schematic description of the memory card insertion / removal control of the information communication apparatus of this embodiment. The operation of the information communication device of this embodiment when a memory card is inserted will be described in detail below with reference to this configuration.

FIG. 30 shows an operation flow chart of the information communication apparatus of this embodiment when the memory card is inserted. This is a card processing routine that branches when it is determined that there is a memory card in ST3 of FIG. 6 described above.

In FIG. 30, when the device is in the standby state (S
When the memory card is inserted in (T300), CD1 and CD2 on the left and right of the card pin become low level, and this is detected to check the insertion (ST301). ST30
If it is 0 and there is no card, it returns to the main program
In 2, the initial screen with no card is displayed. The screen of the LCD 2 at this time is as shown in FIG. 10 as already described. If there is a card, supply power to the card (ST30
2) Connect the system bus with the card together (ST30
3) Then, the attribute information of the card stored in the specific address of the card ROM 122 is read (ST304).
The attribute information will be described below.

FIG. 31 shows a memory map of the memory card of this embodiment. In FIG. 31, 47 is attribute information 1 which is one of management information that stores the type, capacity and access speed of the memory card, and 48 is JE of the memory card.
IDA (Japan Electronics Industry Promotion Association) specification version,
Attribute information 2 and 49, which is one of management information that stores product manufacturer information and product version information, is a memory card specification version, memory card specification compliance level, first data address information, manufacturer individual information, initial The attribute information 3, 50, which is one of the management information storing the manufacturer name and the card information, is an entry point table storing where each module and icon information starts in this memory card, and 51 is actually Is a program area for storing the program and the compressed graphic data of various icons.

Next, the CPU 1 which has read out the attribute information,
It is confirmed whether the read attribute information is valid for the device (ST305), and if it is judged invalid, an alarm is displayed (ST306), power supply to the card is stopped (ST307), and the system bus with the card is cut off. (ST308). After waiting for the card to be removed (ST309), the alarm display is stopped and the operation returns to the standby state. The CPU1 that has determined that the card is valid in ST305
On the standby state screen, the icon data for the menu stored as a dot image in the EEPROM 123 in the card is displayed as V
It is transferred to the RAM 4 and displayed (ST310). At this time,
The CPU 1 has an entry table 50 in the card management area.
In addition to acquiring the address where the actual dot image of the menu icon data set by the manufacturer stored in the card is stored, and the card is one in which the user arbitrarily created and registered the menu icon data, Is
The CPU 1 has an entry table 50 in the card management area.
The address at which the actual dot image of the user-defined menu icon data stored in is stored is acquired. In this embodiment, the icon data for the menu is stored as a dot image, so that the user can arbitrarily create icon data of his / her preference. The screen of the LCD 2 at this time is as shown in FIGS.
Is. Further, as is apparent from these figures, the icon data of the main body side menu and the like provided by the internal ROM 9 and the card side menu icon data provided by the internal ROM 122 or the EEPROM 123 are the main body side and the card side. It is displayed on the LCD 2 regardless of which ROM it is provided from, so that the user can provide it from the card as if he / she was executing the software built in the main body without special knowledge. It is possible to use various software that is used.

CP displaying icon data on LCD2
U1 next determines whether the unique code stored in the RAM 8 of the main body and the unique code stored in the EEPROM 123 of the card match (ST31).
1). The unique code in this embodiment is the data of the month, day, hour, minute and second when the card is inserted into the main body. Since the valid / invalid of the RAM8 data can be determined from the result of this determination, the RAM8 is initialized every time the card is inserted or removed. Not only does it not have to be converted, but when the previously removed card and the inserted card are the same, the information already stored in the RAM 8 of the main body can be used as it is, and necessary data can be stored in the card. There is no need to download it again. If this unique code does not match (ST3
12) The data invalid flag in the main body is set in the RAM 8 (ST313), and the unique code is rewritten at the current card insertion time (ST314). If the unique codes match (ST312), the data valid flag in the main body is set to RAM.
8 (ST315), the FAX save screen data stored in the RAM 8 and the timer automatic start time data of the bank answer system and the like are valid as they are. ST
After 314 or ST315 ends, the CPU 1 determines whether or not the card program is selected (ST316), and when the card program is selected, sets the system reset valid flag (ST317) and shifts to the in-card program (ST318). Thereafter, the CPU 1 constantly monitors the removal of the card until the program ends (ST319) (ST320), and when the card is removed during execution of the card program, resets the system by the configuration shown in FIG. 29 (ST321). Prevent runaway. As a result, the memory card can be inserted and removed without turning off the power of the device, and the CPU 1 does not malfunction even if the power is turned off due to some abnormality during use of the device.
No abnormal data will be written to the memory card. Further, in this embodiment, even if a system reset is applied, the data stored in the internal RAM 8 can be treated as valid unless a different card is inserted by determining the above-mentioned unique code. It is possible to immediately return to the state immediately before that. Even if a different card is set, the data in RAM 8 in the main unit will not be invalidated until the card program is selected after the match / mismatch of the unique code is confirmed. Even if the wrong card is inserted, it goes without saying that the data in the RAM 8 can be prevented from being invalidated by inserting the correct card again.
