Next, the operation of this embodiment configured as described above will be explained with reference to FIG. 8 and subsequent figures.

The microcomputer 121 of the ETW controller 120 starts executing the process shown in FIG. 8 σa when the text key 13 of the keyboard 1 is pressed.

First, enter rTITLENAME on the liquid crystal display device 2.
/DATEJ (title name/year/month/day) is displayed.
Waiting for key personnel. Here, manual input of keys other than the rDJ key or the rTJ key is invalid.

If the ``DJ'' key is input, the process shifts to text search processing based on the date, which will be described later, and if the rTJ key is input, the process shifts to text search processing using the title name or file name, which will be described next.

That is, when the "T" key is input, "rT I TLE/F I LE" is displayed on the liquid crystal display device 2 and the system waits for the key to be pressed. Here, rl? Manual use of keys other than the J key or the "T" key is invalid.

Then, when the ITJ key is input, the process shifts to text search processing by title name, and after registering the title name (file celebrity date) entered manually by the key, a search is made for a file with that title name, and a file with the same title is registered. If there is no text with the same title name, the process moves to newly registered file processing, and if there is a text with the same title name, the process moves to registered file processing.

Also, when the "F" key is input, the process shifts to text search processing by file name, and after registering the file name manually entered by the key, the file with that file name is searched,
If there is no text with the same file name, the process moves to a newly registered file. If there is a text with the same file name, it is determined whether there are multiple texts with the same file name. After performing a text selection process to select one of the texts, if there is only a - text, the process directly proceeds to the registered file process.

In other words, here (file name date) is treated as the title name, so if the year, month, and day differ, the same file name can be used, so sentences with the same file name that differ in one year, month, and day There may be multiple registrations.

In this case, it becomes necessary to select one of those multiple sentences, so for example, sentences with the same file name can be updated and displayed according to the input of the cursor movement key, and the execution key can be used to update the display. A text selection process is performed to select a desired text.

On the other hand, when the rDJ key is input, after registering the date when the key is manually input, the file with the specified date is searched, and if there is a text with the same date, it is searched for. After performing a text selection process to select one of the texts of the year, month, and day, the process moves to registered file processing.

In other words, when searching by date, there may be multiple texts created and registered on the same day.
A process of selecting one of these multiple sentences is performed.

Also, if there is no text with the same date, it is a liquid crystal display device! 2&, Knee rNOT FOUND! After displaying J (corresponding sentence pIF,), wait for the key input to determine whether or not to finish, and if not, display the LCD display [2] again.
The process returns to displaying the "title name/year, month, and date."

Next, the newly registered file processing and registered file processing will be explained with reference to FIGS. 9 and 10.

First, in the new registration file process, power is supplied to the magnet 18 of the RAM card adapter 11 to lock the cover 13.

As a result, the cover 13 of the RAM card adapter 11 cannot be opened from now on, and the cover 13 is released σa while the RAM card 10 is being accessed or a file is being opened. 14 There is no possibility that the card will be removed and the data will be destroyed.

After that, the registered file name is registered at the beginning of the sentence.

In addition, the beginning of the sentence in this case is stored in the sentence memory (RAM123
or the beginning of the empty address of the RAM card To), that is, the beginning of the area (8 bytes worth of addresses) in which text to be created later is registered.

Then, the date data is read from the real-time clock 124 and the current date is registered next to the file name at the beginning of the sentence.

After that, the current routine that processes text data registration, correction, printing, etc. is executed, and when the text key 13 is pressed during this routine, it is determined that the text has been registered, and the text memory date is set to the registered address. After registering the text data from the next address, the v1 power to the magnet 18 of the RAM card adapter 11 is cut off to release the locked state of the cover 13.

Thereby, the cover 13 of the RAM card adapter 11
It becomes possible to open the RAM card 10 and take out the RAM card 10.

Note that in this typewriter, power is constantly supplied to the magnet 18 of the RAM card adapter 11 while text is being created (including corrections, etc.), but for example, if one of the two magnets is If a latch mechanism is provided that locks the cover when the cover is driven and releases the lock when the other magnet is driven, power is supplied to the magnet when the cover is locked and when the cover is unlocked. Since it only needs to be performed when necessary, power consumption is reduced.

In this way, the file name 2 year, month and date and text data are stored in the 2 text memory as shown in FIG. And that cover 13
After locking the file, call the specified file specified by the registered file name or date from the text memory (
file open).

Then, it is determined whether or not to change the year, month, and day. If the year, month, and day are changed, the year, month, and day data is read from the real-time clock 124, and the current year, month, and day are stored in the address that stores the year, month, and day of the opened file. After updating and registering, the same process as the new g and recording rough file process is performed.

In this way, since the file name and date are treated as part of the text, when a file is recalled, the file name and date are also displayed on the liquid crystal display device 2.

Therefore, although not shown in FIG. 5, when printing text, a process is performed to exclude the file name and date from the printed text data.

In addition, when processing is performed to print a list of sentences such as texts stored in the sentence memory, for example, as shown in Fig. 12, the ``r file name'' and ``year, month, and day'' are printed. .

Next, format printing processing for printing the format (layout) of registered text will be described with reference to FIG. 13 and subsequent figures.

The microcomputer 121 starts executing the process shown in FIG. 13 when the code key 16 and the rQJ key (format key) are pressed.

Then, first register the file name entered by the key, and then search for the file with that file name.

At this time, if there is no specified file, display rNOT FOUND! In this case as well, it is also possible to specify the file by year, month, and date.

On the other hand, if there is a designated file, paper size selection processing is first performed to select the format size. This paper size selection process takes in the paper size input manually using the keys.

Then, by using the framing function, a frame is drawn on the paper with a predetermined reduction ratio r 1 / x J of the specified size.

After that, it is determined whether or not there is text data registered in the 2-sentence memory, and if there is registered data.

- Read the print start position and print end position of the data for a line, and set the print start position and print end position at a reduction rate r 1
/ x After converting with J, the - line data is printed by substituting a predetermined character, such as "X".

Then, after carrying out line feed (paper feeding) for one line at the reduction ratio r 1 / Execute, and if there is no registered data, end the process.

In this way, for example, text 1 as shown in FIG.
- as shown in Figure 15, the reduction ratio rl/
By reducing the size with xJ and printing with the substitute character "x",
You can easily see how the text will actually be printed on the paper.

In this way, in this electronic typewriter, when the external text memory is in use, it is made impossible to remove the external text memory, so that the operator cannot accidentally take out the external text memory while the external text memory is in use. I don't want it to be destroyed.

As explained above, according to the present invention, it is possible to prevent data from being destroyed due to removal during access to an external text memory.
