The photosensitive drum 26 has a photosensitive surface 26a charged in advance by a charger 27 prior to scanning exposure by the OFT 25. And photosensitive surface 2
The electrostatic latent image formed on the electrostatic latent image 6a is visualized by applying a developer in a developing device 28, thereby causing an image to appear on the photosensitive surface 26a. The developing device 28 includes a tank 28 ₁ in which toner is stored and a developing chamber 28 ₂ in which the toner in the tank 28 ₁ is replenished. The bottom surface of the tank 28 ₁ and the ceiling surface of the developing chamber 28 ₂ communicate with each other, and the communication portion connects the toner replenishing roller 29 provided at the bottom of the tank 28 ₁ with the roller 29 .

are provided for each. This CPU50 has
A predetermined memory (not shown) is provided.

FIG. 4 shows the control circuit. That is, a predetermined pulse emitted from the pulse generator 60 is supplied as a scanning shift pulse to the photoelectric conversion element 16 in the first reading section 19 ₁ and the photoelectric conversion element 18 in the second reading section 19 ₂ , and these photoelectric conversion elements The video signals output from elements 16 and 18 are sent to CPU 5.
0 respectively, and the VTR is supplied from this CPU50.
The data is supplied to the storage device 23. Further, the video signal read from the VTR storage device 23 by the CPU 50 is supplied to the electrophotographic storage device 24. Also, CPU50
Operation commands and the like are supplied from the keyboard 6.

Next, the operation in the above configuration will be explained. First, turn on the power using the operation key 6 ₁ , place a document X on which required information is written, for example as shown in FIG.
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
The 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 supplied to the VTR storage device 23 via the CPU 50, and the video signals are 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 an update code area B are sequentially formed, and further a heading information area C and a main information area D, in which the heading information and main information are stored, respectively, are formed sequentially. In this way, the search code area A, update code area B, heading information area C, and main information area D are formed as one unit on the tape 20, and the start code from the VTR storage device 23 is stored for each unit. Start code area S
is formed.

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 from the VTR storage device 23 to the CPU 50 is sent to the OFT 25 of the electrophotographic recording device 24.
As a result, 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, all the various information on the document X is recorded, and furthermore, an update code recording field _b1 and an update code entry field _b2 are formed at the upper right end of the recording paper P based on the control command from the CPU 50.

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 second
The search code a and update code "01" are read by the operation of the reading unit 19 ₂ , and these search code a and update code "01" are temporarily stored in the memory within the CPU 50 . At this time, the tape 20
A high speed run is made in the VTR storage device 23,
Moreover, 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 running of the tape 20 is resumed, the update code "01" temporarily stored in the memory is changed to the update code area B on the tape 20.
is memorized. At the same time, the first reading section 19 ₁ operates to read the heading information and main information, and the corresponding electrical signals are stored in the heading 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.

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.
1 and return it to its original location in the tape storage compartment 3 ₂ .

In the above embodiment, the exposure section of the electrophotographic recording device 24 is not limited to the OFT 25, but 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 also magnetic disks,
Various types of memory such as optical memory disks or semiconductor memories may be used.

As described above, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the gist of the invention.
