Fix it with. For example, a numerical search code a is recorded on the upper left end of the document X. Furthermore, heading information c is recorded approximately at the center of the document X, for example, using numbers and alphanumeric characters, and below this heading information c, main information d is recorded. Then, set the tape 20 in the tape insertion slot 21 and enter the search code a.
Enter the number using the numeric keypad 6 ₂ . Then, the set search code is displayed on the digital display 10. When a storage operation is set using the operation key 6 ₁ , the search code is supplied to the VTR storage device 23 via the CPUs 50 and 50 and is stored on the tape 20 . On the other hand, at this time, the first reading section ₁₉₁ reads the heading information c and main information d on the document X on the document table 4, and the video signals corresponding to the various information are sent to the CPUs 50 and 5.
0 to a VTR storage device 23, the video signal of which is stored on tape 20. In this case, as shown in FIG. 6, the tape 20 has a search code area for storing the search code and update code read by the second reading unit 19 ₂ (which does not operate during this storage operation). A
and update code area B are sequentially formed, and furthermore, a heading information area C and a main information area D in which the above-mentioned heading information and main information are stored, respectively, are formed sequentially. In this way, on the tape 20, the search code area A, the update code area B, the heading information area C, and the main information area D are formed as one unit, and the VTR storage device 2
A start code area S is formed in which the start code from .

In this way, the tape 20 on which various information is stored
is taken out from the tape insertion slot 21 by the operator and stored together with other tapes 20 in the tape storage section ₃₂ . In this case, the case of the tape 20 stores the heading and search code of the stored main information.

Here, when it is desired to update the contents (stored information) of the tape 20 corresponding to various information recorded on the recording paper P, the information to be updated on the recording paper P is rewritten. Furthermore, as shown in FIG. 8, a predetermined update code, for example "01", is entered in the update code entry field _b2 . Then, the recording paper P is placed on the document table at a predetermined position and in a predetermined direction, and an update operation is set using the operation key ₆₁ . Then, the search code a and update code "01" are read by the operation of the second reading section ₁₉₂ , and these search code a and update code "01" are read by the CPU 50, 50.
Temporarily stored in internal memory. At this time, the tape 20 is run at high speed in the VTR storage device 23, and the search codes on the tape 20 are read out one after another. When the search code read from the tape 20 matches the search code temporarily stored in the memory, the tape 20 stops running. As the tape 20 resumes running, the update code "01" temporarily stored in the memory is stored in the update code area B on the tape 20. At the same time, the first reading section 19
₁ is operated, the headline information and main information are read, and the corresponding electrical signals are stored in the headline information area C and main information area D on the tape 20, respectively. That is, the various information (old information) stored on the tape 20 is rewritten with new information.

Thereafter, when the updated information is updated again, the information printed on the recording paper P by the search operation becomes as shown in FIG. 9. That is, the update code "01" is recorded in the update code recording field _b1 . In this case, it can be determined by the update code "01" that the update operation has been performed once. When performing a second update, after completing a predetermined update to the information, an update code, for example "02", is entered in the update code entry field _b2 for the information update. The subsequent operations are similar to those described above.
