FIG. 11 is a flowchart of a process in which the desktop personal computer 11 reads an address book file stored in the RAM 43 (or the EEPROM 49) of the portable personal computer 1 and performs a new input or a correction input. Is shown.

First, in step S31,
CPU 6 of desktop personal computer 11
1 determines whether an instruction to read an address book file is input from the keyboard 14 (operation of an address key) or the mouse 16. If it is determined that the read command has been input, the process proceeds to step S32 and the CPU 6
1 requests the transfer of the bus management to the CPU 41 of the portable personal computer 1 via the connection unit 15 and the connection unit 4. When receiving this request, the CPU 41 transfers the bus management right in the portable personal computer 1 to the CPU 61.

In step S 33, the CPU 61 to which the bus management right has been passed is used as the management device by the RAM 43 or the EEPROM 49 already registered.
And directly read the address book file recorded there. Then, the CPU 61 temporarily stores the read address book file in the buffer area of the RAM 63 and outputs display data of the address book file to the display 12 for display. If it is determined in step S31 that the reading of the address book file has not been instructed, the subsequent operation is not performed.

Next, the operation proceeds to step S34, where the CPU 61
Determines whether a command to read out predetermined address book data has been input from the keyboard 14 or the mouse 16. If it is determined that the read command has been input, the process proceeds to step S35, in which the CPU 61 reads the requested address book data from the RAM 63 and reads the address book data.
And display it.

Next, in step S36, the CPU 61
Determines whether a write command has been input from the keyboard 14 or the mouse 16. If a write command has been input, the process proceeds to step S37, where the CPU 61
Temporarily stores the new address, address correction data, and the like input by the user operating the keyboard 14 in the buffer area of the RAM 63, and proceeds to step 38. Then, in step 38, the CPU 61 determines whether or not a write (update) as an address book has been instructed from the keyboard 14 or the mouse 16. When an update command is input, the CPU 61 determines in step S39 that R
The address book file is updated based on these data stored in the buffer area of the AM 63.

Then, the process proceeds to a step S40, wherein the CPU 6
1 determines whether an instruction to end the address book processing has been input from the keyboard 14 or the mouse 16.
When an instruction to end the processing of the address book is input, the process proceeds to step S41, and the CPU 61 executes processing of transferring the file of the address book stored in the RAM 63 to the RAM 43 or the EEPROM 49 of the portable personal computer 1.

That is, in order to execute this transfer processing,
The CPU 61 requests the CPU 41 to accept the bus management right. The CPU 41 determines whether or not there has been a request from the CPU 61 to accept the bus management right in step S46 of the flowchart in FIG. If there is a request to accept the bus management right, the process proceeds to step S47, where the CPU 41 receives the transfer of the bus management right,
The address book file stored in the buffer area of the RAM 63 is read out, and the buffer of the RAM 43 of the portable personal computer 1 or the buffer of the EEPROM 49 is connected via the connection unit 15 of the desktop personal computer 11 and the connection unit 4 of the portable personal computer 1. Store in the area. And the file of this address book is R
When stored in the AM 43, the CPU 41 further sets R
From the buffer area of AM43, EEPR
It is recorded in the address book area of OM49. Then, this operation is ended. On the other hand, in step S46, if there is no request to accept the bus management right, the subsequent processing is not executed.

Instead of transferring the bus management right to the CPU 41, it is also possible to transfer the bus management right to the DMA controller 64. In this case, in order to execute the transfer processing, the CPU 61 requests the DMA controller 64 to accept the bus management right. When the DMA controller 64 receives the transfer of the bus management right, the DMA controller 64
The file of the address book stored in the buffer area 63 is transferred to the RAM 43 of the portable personal computer 1 via the connection unit 15 of the desktop personal computer 11 and the connection unit 4 of the portable personal computer 1.
Alternatively, the EEPROM 49 (in step S1 of FIG. 8, the CP
DMA transfer to a buffer area (registered as a management device of U61). This address book file is
When the data is transferred to the RAM 43, the CPU 41 further outputs E from the buffer area of the RAM 43 as necessary.
The data is transferred to the address book area of the EPROM 49 and recorded.

Returning to the processing of FIG. 11, if it is determined in step S34 that a command to read out predetermined address book data has not been input, the processing of steps S35 to S39 is skipped. Further, if it is determined in step S36 that a write command has not been input, steps S37 to S39 are performed.
Is skipped. If it is determined in step S38 that the update command has not been input, the process of step S39 is skipped. If it is determined in step S40 that the end of the address book processing has not been instructed, the process returns to step S34,
Subsequent processes are repeatedly executed.

Next, a description will be given of an operation when the electronic mail function (transmission processing and reception processing) is executed in a state where the personal computer is integrated.

The portable personal computer 1 has an e-mail function (wireless communication function or wired communication function), and uses the e-mail function of the portable personal computer 1 to operate the portable personal computer 1 or desktop computer. When transmitting the transmission data generated by the personal computer 11, the CPU 61 of the desktop personal computer 11
The processing shown in the flowchart of FIG. 3 is executed, and the CPU 41 of the portable personal computer 1 executes the processing shown in the flowchart of FIG.

The portable personal computer 1 and the desktop personal computer 11 have a function of creating data to be transmitted as e-mail or facsimile (function as a word processor) and a communication for transmitting and receiving e-mail itself. Although the portable personal computer 1 has the function, the case where the transmission data of the e-mail generated by the desktop personal computer 11 is transmitted by the wireless communication function of the portable personal computer 1 will be described below as an example.

First, the operation of the electronic mail transmission process will be described. Desktop personal computer 1
In step S51 of the flowchart of FIG. 13, the first CPU 61 determines whether or not an instruction for an electronic mail transmission process has been input from the keyboard 14 (operation of the transmission key) or the mouse 16. When it is determined that the instruction for the e-mail transmission processing has been input, the CPU 61 proceeds to step S52 and requests the CPU 41 of the portable personal computer 1 to execute the e-mail transmission. In step S51, if the e-mail transmission processing is not requested, the subsequent operation is not performed.

CPU of portable personal computer 1
41 executes the processing shown in the flowchart of FIG. 14 in response to this request. First, first, the CPU 41
In step S71, it is determined whether an e-mail transmission request has been received from the CPU 61. If a request to send an e-mail has been received, the process proceeds to step S72,
The CPU 41 determines whether or not transmission data is stored in the buffer area of the RAM 43. If the transmission data has already been input by operating the keyboard 3 of the portable personal computer 1 and has already been stored in the buffer area of the RAM 43, the process proceeds to step S73, where the CPU 41 stores the transmission data in the RA.
The data is read from the buffer area of M43 and supplied to the wireless communication unit 47. The wireless communication unit 47 modulates the supplied transmission data, converts the data into transmission radio waves, and transmits the transmission radio waves via the antenna 5. This transmission radio wave is transmitted, for example, to the nearest base station 21-1.
, And then transmitted to a predetermined destination via another base station 21-2 or the network 22. Then, the process proceeds to step S74, in which the CPU 41
Is notified of transmission data transmission completion. In step S71, if the e-mail transmission processing is not requested, the subsequent processing is not executed.

In step S72, the transmission data is R
If it is determined that the transmission data has not been stored in the buffer area of the AM 43, the process proceeds to step S75, and the CPU 41 determines whether the transmission data is stored in the buffer area of the RAM 63 of the desktop computer 11. R
If the transmission data is stored in the buffer area of the AM 63, the process proceeds to step S76, where the CPU 41
The transmission data stored in the buffer area 3 is read and stored in the buffer area of the RAM 43. Then, the process proceeds to step S73, and the transmission data is read from the buffer area of the RAM 43 and transmitted by the wireless communication function. On the other hand, if it is determined in step S75 that the transmission data is not stored in the buffer area of the RAM 63, the process proceeds to step 77, where the CPU 41
A request for transmission data is made to 61.

Desktop type personal computer 1
The first CPU 61 determines in step S53 whether or not a notification of transmission data transmission completion or a request for transmission data input has been input from the CPU 41. When the notification of the transmission data transmission completion is received, the CPU 61 determines in step S5
Steps 4 to S58 are skipped. On the other hand, if the request for transmission data input has been received, the process proceeds to step S54.
The CPU 61 generates a message prompting input of transmission data and causes the display 12 to display the message. As a result, a message such as “Please input transmission data” is displayed on the display 12. At this time, the CPU 41 communicates with the CPU 61 and
The PU 41 sends a similar message to the LCD as necessary.
2 can also be displayed.

When viewing the message, the user operates the keyboard 14 to input transmission data. Then, in step S55, the CPU 61 determines whether or not transmission data has been input from the keyboard 14 or the mouse 16. If the transmission data has been input, the process proceeds to step S56, and the input transmission data is stored in the RAM.
Once stored in the buffer area 63, the process proceeds to step S57.

Next, in step S57, the CPU 6
1 determines whether or not a command to complete transmission data input has been input from the keyboard 14 or the mouse 16. When the command to complete the input of the transmission data is input, the process proceeds to step S58, where the CPU 61 notifies the CPU 41 that the transmission data of the electronic mail stored in the buffer area of the RAM 63 has been stored.

CPU of portable personal computer 1
In step S78, the desktop personal computer 11 receives a notification from the CPU 61 in step S78.
It is determined whether the storage of the transmission data in the buffer area of the RAM 63 has been completed. If the transmission data has not been stored in the buffer area of the RAM 63, the processing of steps S73 and S74 is skipped. On the other hand, when it is determined in step S78 that the storage of the transmission data in the buffer area of the RAM 63 has been completed,
Proceeding to step S79, the CPU 41 reads out the transmission data from the RAM 63 and stores it in the buffer area of the RAM 43. Then, the process proceeds to step S73, and the transmission data is transmitted by the wireless communication function.

Instead of storing the transmission data from the buffer area of the RAM 63 to the buffer area of the RAM 43 by the CPU 41, the transmission data may be transferred by the DAM controller 64. In that case, the CPU 41
It requests the DMA controller 64 to accept the bus management right. Upon receiving this request, the DMA controller 64 receives the transfer of the bus management right, and DMA-transfers the transmission data of the electronic mail stored in the RAM 63 to the RAM 43.

If it is determined in step S55 that the command to input the transmission data has not been input,
Steps S56 to S58 are skipped. If it is determined in step S57 that the command to complete the input of the transmission data has not been input, the process of step S58 is skipped.

In step S59, the CPU 61 of the desktop personal computer 11 determines whether an instruction to end the e-mail transmission process has been input from the keyboard 14 or the mouse 16.
If a command to end the e-mail transmission process is entered,
The CPU 61 proceeds to step S60, notifies the CPU 41 of the end of the e-mail transmission process, and ends the e-mail transmission process. On the other hand, if it is determined in step S59 that the end of the e-mail transmission process has not been instructed, the process returns to step S51, and the subsequent processes are repeatedly executed.

Further, the CPU 41 of the portable personal computer determines in step S80 whether or not the notification of the end of the e-mail transmission processing has been received from the CPU 61. When the notification of the end of the e-mail transmission process is received, the CPU 41 ends the e-mail transmission process. On the other hand, if it is determined that the notification of the end of the e-mail transmission processing has not been received, the CPU 41 returns to step S71, and the subsequent processing is repeatedly executed.

Next, the operation of the e-mail receiving process will be described. The network 22 or the base station 2
When executing an e-mail function such as receiving e-mail data from 1-i, the CPU 61 of the desktop personal computer 11 executes the processing shown in the flowchart of FIG. Executes the processing shown in the flowchart of FIG.

First, in step S81, the CPU 61 of the desktop personal computer 11 determines whether or not a command to confirm or display received data has been input from the keyboard 14 (operation of the data reception key) or the mouse 16. When a command to confirm or display the received data is input, the CPU 61 proceeds to step S82 and determines whether the received data is stored in the buffer area of the RAM 63. In step 82, RA
If it is determined that the received data is stored in the buffer area of M63, the process proceeds to step S83, where the CPU 61
Reads the received data from the buffer area of the RAM 63 and supplies it to the display 12 to display the received data. Then, the confirmation or display operation of the received data is terminated.

On the other hand, if it is determined in step S82 that the received data is not stored in the buffer area of the RAM 63, the process proceeds to step S84, where the CPU 61
Supplies a request for confirmation as to whether or not the received data is received by the portable personal computer 1 to the CPU 41 of the portable personal computer 1 and proceeds to step S8.
Go to 5.

If it is determined in step S81 that a command to confirm or display received data has not been input, the process also proceeds to step S85. The CPU 61 determines in step S85 that the portable personal computer 1
Is determined from the CPU 41 (notification of whether or not the received data is written in the buffer area of the RAM 43). When the notification from the CPU 41 has not been received, or when the notification from the CPU 41 is a notification that there is no received data, the process proceeds to step S86, and the CPU 61 generates a message indicating that there is no received data, and displays Let it. As a result, a message such as “no received data” is displayed on the display 12. At this time, the CPU 41 may cause the LCD 2 to display a similar message. Then, this operation is ended.

On the other hand, when the notification from the CPU 41 is received,
If the notification is that you have data to receive,
Proceeding to step S87, the CPU 61 reads the received data from the buffer area of the RAM 43 and stores it in the buffer area of the RAM 63. Then, the process proceeds to step S88, where the CPU 61 determines whether the keyboard 14 or the mouse 1
From 6, it is determined whether a command to confirm or display received data has been input. If an instruction to confirm or display received data has been input, the process proceeds to step 83, where CP
U61 reads the received data from the buffer area of the RAM 63, supplies the received data to the display 12, and displays the received data. On the other hand, step S8
At 8, from the keyboard 14 or the mouse 16,
If it is determined that the instruction to confirm or display the received data has not been input, the process proceeds to step S89, and a message indicating that there is received data is displayed on the display 12. Thereafter, this operation is ended. As described above, such an operation of the CPU 61 is executed when there is a request from the keyboard 14 or the mouse 16.

In step S91, the CPU 41 of the portable personal computer 1 determines whether a request for confirmation of received data has been received from the CPU 61, and also determines whether a set predetermined time has elapsed. When a request for confirmation of received data is received or when a set predetermined time has elapsed, the CPU 41
Proceeding to a step 92, it is determined whether or not data of the electronic mail from the base station 21-i exists. If there is data to be received, the CPU 41 proceeds to step S93,
A process for storing the received data in the buffer area of the RAM 43 is executed. That is, the wireless communication unit 47 receives the data transmitted from the base station 21-i via the antenna 5, and demodulates the received data. Then, the demodulated received data is stored in the buffer area of the RAM 43, and the process proceeds to step S94. If it is determined in step 91 that the request for confirmation of the received data has not been received and that the set predetermined time has not elapsed, the subsequent processing is not executed.

Next, in step S94, the CPU 4
1 displays on the LCD 2 that the received data has been written in the buffer area of the RAM 43 (only the received data when the elapse of the predetermined time has been determined) and the RAM 4
That the received data is stored in the buffer area of the desktop personal computer 11
U61 is notified, and the operation is terminated. If it is determined in step 92 that there is no e-mail data, in step 95, the CPU 41
The CPU 61 is notified that there is no received data, and the operation is terminated. The received data stored in the buffer area of the RAM 63 may be recorded on the hard disk 67. That is, such a CPU
The operation of 41 is executed when there is a confirmation command from the CPU 61 or at predetermined time intervals.

As described above, one of the CPUs makes the other RA
M (from the CPU 41 of the portable personal computer 1 to the RAM 6 of the desktop personal computer 11)
3 or desktop personal computer 11
From the CPU 61 of the portable personal computer 1
Since the user can directly access the AM 43), it is not necessary to hold the information file independently in each RAM, and the operability is improved.
