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.
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 title and search code of the main stored information are written on the case of the tape 20.

Thereafter, when certain key information is required, the operator takes out the required tape 20 from the tape storage section ₃₂ and sets it in the tape insertion slot 21. Then, enter the search code corresponding to the required main information on the numeric keypad 6 ₂ , and press the operation key 6 ₁ .
Set the search behavior by. Then, the tape 20 is run at high speed in the VTR storage device 23, and a desired search code on the tape 20 is searched. However, when the search is completed, tape 2
A normal run of 0 is performed, and the video signals stored on the tape 20 are sequentially read out. thus,
The video signal read out from the VTR storage device 23 to the CPUs 50, 50 is transmitted to the electrophotographic recording device 24.
The signal is supplied to the OFT 25, whereby various information based on the video signal is recorded on the recording paper P. At this time, the recording format on the recording paper P is as shown in FIG. That is, the original document
All types of information are recorded, and the CPU
Based on the control commands 50 and 50, an update code entry column b ₁ and an update code entry column b ₂ are formed at the upper right end of the recording paper P.

Now, when you want to change or modify the contents (memory information) of the tape 20 corresponding to various information recorded on the recording paper P, change or modify the information on the recording paper P on which the relevant information is recorded. to do. For example, recorded information may be changed or corrected, or new information may be added.
Furthermore, as shown in Figure 8, update code entry field

Thereafter, the recording paper P on which the information has been changed or corrected 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 CPUs 50 and 50.
is 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. Then, when the search code read from the tape 20 matches the search code temporarily stored in the memory, the running of the tape 20 is temporarily stopped. 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
operates, the heading information and main information are read, and the corresponding electric signals are updated and stored in the heading information area C and main information area D on the tape 20, respectively. That is, part or all of the various information (old information) stored on the tape 20 is rewritten with new information.

Thereafter, when the updated information is to be updated again, the information printed on the recording paper P by the search operation becomes as shown in FIG. 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.

In this way, when the required main information recording or information updating is completed, the tape 20 is inserted into the tape insertion slot 2.

In the above embodiment, necessary information is searched from the tape 20 based on a search code set in advance and recorded on the recording paper P, and the information recorded on the recording paper P is changed or corrected. Then, by reading this recording paper P with the reading units 19 ₁ and 19 ₂ , the area of the tape 20 where the above-mentioned required information is recorded is searched based on the search code a on the recording paper P, The above-mentioned changed/corrected information is updated and stored in this area, but a search code set in advance is temporarily held in the memory of the CPU 50, and based on this held search code, the tape 2 The area in which the above-mentioned necessary information is recorded may be searched. That is, this can be applied even when no search code is recorded on the recording paper P. moreover,
The information to be stored on the tape 20 is not limited to text, but may also be, for example, drawings. Further, the exposure section of the electrophotographic recording device 24 is not limited to the OFT 25, and may be one that performs scanning exposure using a laser. Furthermore, the storage medium is not limited to the endless video cassette tape 20, but may be any other type of memory such as a magnetic disk, disk memory, or semiconductor memory.

In this way, the present invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the gist of the invention.

As described above, according to the present invention, the information is changed or corrected on a recording medium in which required information is recorded, and the changed or corrected information is stored by reading this recording medium with a reading unit. Since the above-mentioned required information is updated and stored in the recorded area of the medium, the information on the storage medium can be easily updated by a simple operation, and the storage area on the storage medium can be used effectively. It is possible to provide an information storage and retrieval device that can also measure information.
