By monitoring, the CPU 1 is configured to be able to recognize whether or not the portable electronic device 20 is attached.

On the other hand, on the portable electronic device side B, 11 is, for example, a CPU.
Based on the control program stored in the ROM 11a, the separation processing unit operates as an electronic notebook device when the connector unit 7 is not attached (when it is a standalone unit), and as a document processing device when it is attached to the connector unit 7. The pass line 7b functions as an auxiliary display section and displays auxiliary display items transferred via the connector section 7, such as user messages for rFDFD exchange, layout state 1 selected kanji candidates, word registration 1 time, and operation guides such as image data. Each unit is controlled to transfer the information to the display unit 14 via the .

As shown in FIG. 3(a), when the electronic device body 20 is not attached to the connector attachment port 21, the attachment signal is on (signal line 7a is at H level), so document processing is not possible. When a request to display an auxiliary item is made in parallel, the VRAM 4a corresponding to that window position is cleared and the auxiliary item, for example rFDFD replacement, is displayed together with the window 23. This causes the operator to interrupt document processing and take some workaround. I will give a lecture. Then, when document processing can be started, the contents of the VRAM 4a corresponding to the window 23 are restored to the corresponding document data stored in the storage section 3.

On the other hand, as shown in FIG. 3(b), the connector mounting port 2
When the electronic device body 20 is attached to the electronic device 1, the attachment signal is turned off (signal line 7a is at L level), and the CPU 1 sets this state in the storage section 3 as flag information.

Here, when a request to display an auxiliary item is made in parallel with the document processing, after confirming that the electronic device main body 20 is attached based on the flag information, the character code for the auxiliary item, for example, "rFD replacement" is sent to the pass line 7b, the connector part Transfer writing is performed to the storage unit 12 via 7.

This makes it possible to auxiliary display the window display items on the display unit 14, thereby preventing temporary destruction of the document screen and avoiding interruption of the thinking process in document processing.

The character patterns stored in the V
It is stored in the RAM 4a and displayed (1).

When the conversion for one screen is completed, it is determined whether there is any data to be displayed other than the window or text 2). If NO, proceed to step (6) and onwards, and Y
If ES, it is determined whether the electronic device main body 20 is attached to the connector mounting port 21 (3), and if YES, the window display information (auxiliary display item) is displayed on the electronic device main body 20.
The letter is started in the storage unit 12 (4), and the process proceeds to step (6) and subsequent steps.

On the other hand, if the judgment in step (3) is NO, the VRAM
The contents corresponding to the window display position 4a are erased and the window contents are written (5).

Next, the electronic device body 2 enters the state of waiting for human power (6).
When the power switch 0 (not shown) is pressed, interrupt requests such as key input and floppy disk input/output from the input unit 13 are processed (7), and the display unit is activated based on the transferred and written auxiliary item data. The external display routine to be displayed at 14 is started.

In the above embodiment, a case has been described in which the auxiliary items are transferred and displayed on the display section 14 based on the auxiliary item data transferred from the document processing device side A, but the auxiliary items are displayed on the display section 14 of the electronic device main body 20. It is also possible to display a list of a large-capacity database, such as an address book, on the display unit 4 of the document processing device A.
