This is a display section that displays messages etc. indicating the following.

Here, the nonvolatile storage device 4 constitutes a supply means, and the CPUI constitutes a determination means, an identification information registration means, a reading means, and a control means.

Next, the operation of this embodiment will be explained. Usually, the CPUI
recognizes, via the input/output controller 5, a key code entered manually from the operating unit 6 according to a program stored in the program memory 3, and performs document editing processing in accordance with the recognized key code while using the RAM 2. At this time, if the input key code instructs, for example, to save a document or the like in the cartridge type memory 7 attached to the main body of the apparatus, the CPU performs processing according to the flowchart shown in FIG. 2.

When the cartridge-type memory 7 is accessed, the CPUI waits for an access request to the cartridge-type memory 7 in step 201, and when an access request occurs, the process proceeds to step 202. In step 202, the process of reading out the identification information 50 written in the cartridge type memory 7 is performed.At this time, in step 203, it is determined whether or not the identification information 50 is present.If not, step 2
Proceed to 04. In step 204, it is determined whether the access is a write process, and if it is not a write process, the process proceeds to step 206, and if it is a write process, the process proceeds to step 210. In step 210, the identification information 50 is read from the non-volatile storage device 4, and is stored (registered) in a predetermined area of the cartridge type memory 7, after which the process advances to step 206.

On the other hand, if it is determined in step 203 that there is identification information 50, the process proceeds to step 205 to determine whether the identification information 50 read from the cartridge type memory 7 matches the identification information 50 read from the nonvolatile storage device 4. Determine whether As a result, if the two pieces of identification information match, the process proceeds to step 206; if they do not match, step 2
Proceed to 07. In step 206, access to the cartridge type memory 7 is permitted, and in step 208, the cartridge type memory 7 is accessed to write or read documents, etc., and then the process proceeds to the next process. On the other hand, in step 207, access to the cartridge type memory 7 is prohibited, and the process proceeds to step 209, where a message indicating that the cartridge type memory 7 cannot be accessed via the input/output controller 5 is displayed on the display unit 10. After that, proceed to the next process.

Here, in the above explanation, the identification information written in advance in the nonvolatile storage device 4 at the time of manufacturing the device, etc. is read out as is and written in the cartridge type memory 7, but the identification information stored in the nonvolatile storage device 4 is The identification information is a serial number, etc., and when storing the identification information in the cartridge type memory 7, the serial number is converted according to a predetermined rule to create the identification information, and this is written to the cartridge type memory 7. It can also be done.

According to this embodiment, when a new cartridge type memory 7 is installed in the device and information such as an address book is written to the cartridge type memory 7, identification information is automatically stored in the cartridge type memory 7. Therefore, there is no need for the user to perform an operation to protect the information stored in the cartridge type memory 7, and the operability can be improved accordingly. In addition, when the device accesses the cartridge type memory 7, the cartridge type memory 7
Only when the identification information stored in the device matches the identification information in the device, the cartridge type memory 7 is accessed to read out information, for example, so that each time the cartridge type memory 7 is accessed, it is necessary to read the information. It is no longer necessary for the user to input a password, etc., which improves the operability of the device, and even if the user forgets the password, the cartridge type memory 7 can be accessed, making it easier to manage the password. The burden on the user can be reduced by eliminating the need to do so. Furthermore, since the identification information stored in the cartridge type memory 7 is created within the device, it cannot be easily decoded by others, and the reliability of information protection can be improved.

Note that the same effect can be obtained even if a battery backup type RAM is used as the cartridge type memory 7 shown in the above embodiment. Further, the identification information 50 stored in the non-volatile storage device 4 of the above embodiment may be registered by the user of the information processing device when starting to use the device. Furthermore, a configuration may be adopted in which the user selects whether or not to register the identification information using the operation unit 6.
