There is little room to enter owner identification information such as the owner's name and contact information on each device, and even if there is room to enter, it is unclear, so no such situation is entered. Is normal. Therefore, if lost, it may not be possible to contact the owner. Also, if the owner changes, the information about the previous owner must be deleted.

An object of the present invention is to provide a small electronic device that can display arbitrary information such as the owner of the device only by turning on the power supply and can prevent further operation by a person who does not have the proper authority. To provide.

(Means for Solving the Problems) A small electronic device according to the present invention has a data input means and a display device, and displays an initial screen including display of owner identification information for identifying an owner when the power is turned on. A first display mode for displaying, an initial screen including a display for displaying the owner identification information and a prompt for password input when the power is turned on, and a second display mode for not displaying the initial screen when the power is turned on. It is a small portable electronic device equipped with 3 display modes.

This electronic device is a data storage unit in which the contents of the stored owner identification information can be rewritten by operating the data input unit, a display mode required from the first to third display modes. When the power is turned on, the mode setting means for selecting and setting is selected according to the display mode set by the mode setting means, and the owner identification stored in the data storage means is displayed on the display device. When the predetermined password is input, the operation of the small electronic device is started when the content of information and a prompt text for inputting a password are displayed, and when the second display mode is set. It is equipped with a means to make it. Thereby, the above object is achieved.

(Operation) In the present invention, when the power is turned on, the first display mode for displaying the initial screen including the display of the owner identification information for identifying the owner, and the display of the owner identification information and the password when the power is turned on. A second display mode for displaying an initial screen including a display prompting for input and a third display mode for not displaying the initial screen when the power is turned on are selected by the mode setting means. Therefore, by setting the display mode by the owner, it is possible to display the owner's identification information and even display the password prompt by simply turning on the power. As a result, it is possible to solve the problem that it is difficult to distinguish one's own from others of the same model, and the problem that the stored data is corrupted by the operation of another person.

Further, since the owner identification information is stored in the data storage means that can be rewritten by operating the data input means, even if the owner or the like changes, the identification information of the previous owner is You can easily replace it with that of the current owner.

Next, the operation when the power of the electronic notebook 1 is turned on, that is, when the [ON] key 41 is pressed will be described with reference to FIG. First, in step S1, it is determined whether or not the mode for displaying the startup screen is set by checking whether or not the data in the display mode area 111 is "0". When the data is “0”,
The startup screen is not displayed, and a predetermined application program is started. If the data is not "0", the start-up data area 11 is determined in step S2.
The current date and day of the week obtained based on the data such as the owner name stored in 4 and the information read from the RTC 11 are displayed. In step S3, the data in the display mode area 111 indicates "2" whether or not the mode for requesting the password input is set on the startup screen.
It judges by checking whether or not. If the data is "2", the process proceeds to step S4, but if it is not "2" (that is, "1"), the process proceeds to step S9 to wait for a key operation.

In step S4, it is determined whether or not a password is set by checking the first byte of the password buffer 112. If the first byte is not "00h", the password has been set and the process proceeds to step S5. If the first byte is "00h", the password has not been set and therefore the process proceeds to step S8.

In step S5, a prompt statement "ENTER PASSWORD []" for prompting the input of the password is displayed next to the data displayed in step S2. The password (character string) entered by the user is the password input buffer.
It is stored in 113 (step S6). In step S7, it is determined whether or not the password in the password buffer 112 and the character string stored in the password input buffer 113 match. If they do not match, the process returns to step S6. If the two match, a predetermined application program is started.

In step S8, a message "PASSWORD IS NOT ENTERED" indicating that the password has not been set is displayed.
Next, when any key is pressed in step S9, a predetermined application program is started.

4A to 4I show start-up screens of this embodiment. FIGS. 4A to 4C show start-up screens in the case where the mode in which the prompt statement prompting for the password is not displayed is set. The difference between the startup screens in FIGS. 4A to 4C is that the images displayed in the display area on the right side of the screens are different. Which of these images is displayed on the startup screen is set by the user in a special mode of the electronic notebook 1. First
FIGS. 4D to 4F show start-up screens in the case where the mode for displaying the prompt statement prompting for the password is set. FIG. 4G to FIG. 4I show a start-up screen in a case where a mode for displaying a prompt statement prompting for a password is set, but the password is not set.

In the above embodiment, the contents of the start-up screen are the owner's name, telephone number and address, and the current date, but various other data can of course be displayed on the start-up screen.

(Effect of the Invention) According to the present invention, the information of the owner or the like can be displayed only by turning on the power supply, and the person who does not know the password, that is, the person who does not have the proper authority can operate the information. There is provided a small electronic device capable of preventing the above. If the information displayed when the power is turned on includes the owner's name, contact information, etc., the user can easily distinguish his or her own device from multiple similar devices. Furthermore, the non-owner can easily know the contact information for the owner of the lost device.
