Here, when it is desired to update the contents of the tape 20 (description 1 information) corresponding to various information recorded on the recording paper P, four changes of the information to be updated on the recording paper P are performed. 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 keys 61. Then,
The search code a and the update code "01" are read by the operating pressure of the second reading section 192, and the search code a and the updated IFr code "01" are temporarily stored in the memory within the CPU 50. 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 successively output. 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 chip 200 is restarted, 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 191 operates to read the heading information and main information, and the corresponding electrical signals are stored in the heading information area C and the main information receiving area on the tape 20, respectively. That is, the various information (old information) stored on the tape 20 is overwritten with new information.

However, when the updated information is to be updated again, the information printed on the recording paper P by the search operation is the ninth
It will look like the figure. That is, the update code "01" is recorded in the update code record @blK. In this case, it can be determined that the update operation has been performed once by the update code "01", which is 5. 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 @bz 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 taken out from the tape insertion slot 21,
