Abstract

When power is turned on, control unit requests a user to enter a security code on the basis of information of SIM card inserted into a card I/F. If the security code entered by the user is an authorized code, the control unit permits the user to use the apparatus such that the apparatus can be utilized. In addition, the control unit urges a display unit to display a security code entered through operation unit, as hidden letters, and to display a control command such that the control command can be visually recognized.

Claims

1. A mobile radio terminal apparatus comprising:

display unit configured to display at least text information;

entry unit configured to accept entry of a letter; and

display control unit configured to control the display unit to display a letter being different from the letter accepted by the entry unit,

wherein if a letter preset by the entry unit is entered, the display control unit controls the display unit to display the letter accepted by the entry unit.

2. The apparatus according to claim 1, wherein the letter preset is a predetermined letter indicating a control command;

and

further comprising control unit configured to execute the control command corresponding to the predetermined letter accepted by the entry unit.

3. A mobile radio terminal apparatus comprising:

display unit configured to display at least text information;

entry unit configured to accept entry of a letter; and

display control unit configured to, if entry of a security code is accepted, control the display unit to display a letter being different from the security code accepted by the entry unit,

wherein if entry of the security code is capable of being accepted and a letter preset by the entry unit is entered, the display control unit controls the display unit to display the letter preset accepted by the entry unit.

5. The apparatus according to claim 3, further comprising communications control unit configured to, if entry of the security code is accepted, transmit the entered the security code to a storage medium which stores a predetermined security code, and configured to be capable of connecting to a network after the entered security code and the predetermined security code are successfully authenticated by the storage medium.

4. A mobile radio terminal apparatus comprising:

display unit configured to display at least text information;

entry unit configured to accept entry of a letter;

display control unit configured to, if entry of a security code is accepted, control the display unit to display a letter being different from the security code accepted by the entry unit,

wherein if entry of the security code is capable of being accepted and a predetermined letter indicating a control command is entered by the entry unit, the display control unit controls the display unit to display the predetermined letter accepted by the entry unit; and

control unit configured to execute the control command corresponding to the predetermined letter accepted by the entry unit.

6. The apparatus according to claim 4, further comprising communications control unit configured to, if entry of the security code is accepted, transmit the entered the security code to a storage medium which stores a predetermined security code, and configured to be capable of connecting to a network after the entered security code and the predetermined security code are successfully authenticated by the storage medium.
