Mobile terminal
First Claim
1. A mobile terminal shifting a state between a restricted state for restricting a key operation and an unrestricted state for making a key operation unrestricted, comprising:
- a first selector for selecting said unrestricted state when a PIN code is input by a code inputting operation in a first restricted state for restricting a key operation so as to not perform a function associated with the key operation, excluding at least the code inputting operation;
a second selector for determining whether a number of unsuccessful code inputting operations in said first restricted state is above a threshold value, selecting said first restricted state when it is determined that the number of unsuccessful code inputting operations is not above the threshold value, and selecting a second restricted state for restricting a key operation including at least the code inputting operation when it is determined that the number of unsuccessful code inputting operations is above the threshold value;
a communicator for executing a short range radio communication with an external communication device; and
a threshold changer for determining a possibility of a key operator being a qualified person and increasing said threshold value when said possibility is determined to be high, wherein said threshold changer determines that said possibility is high when said terminal itself is inside a predetermined area, and determines that said possibility is low when said terminal itself is outside said predetermined area.

Abstract
A mobile terminal includes a processor shifting a state between a first restricted state for restricting a key operation except for at least a code inputting operation, a second restricted state for restricting a key operation including at least said code inputting operation, and a unrestricted state for making a key operation unrestricted. The processor selects the unrestricted state when a code input by the code inputting operation in the first restricted state is a preset code. Furthermore, whether or not the number of executions of the code inputting operation in the first restricted state is above a threshold value is repetitively determined, and if the determination result is negative, the first restricted state is selected while if the determination result is affirmative, the second restricted state is selected. Then, a possibility of a key operator being a qualified person is repetitively determined, and as the possibility is high, the threshold value is made large.

5. A non-transitory recording medium storing a control program of a mobile terminal shifting a state between a restricted state for restricting a key operation and an unrestricted state for making a key operation unrestricted, wherein
said control program causes a processor of said mobile terminal to execute a first selecting step for selecting said unrestricted state when a PIN code is input by a code inputting operation in a first restricted state for restricting a key operation so as to not perform a function associated with the key operation, excluding at least the code inputting operation; -
a second selecting step for determining whether a number of unsuccessful code inputting operations in said first restricted state is above a threshold value, selecting said first restricted state when it is determined that the number of unsuccessful code inputting operations is not above the threshold value, and selecting a second restricted state for restricting a key operation including at least the code inputting operation when it is determined that the number of unsuccessful code inputting operations is above the threshold value; a communication step for executing a short range radio communication with an external communication device; and a threshold changing step for determining a possibility of a key operator being a qualified person and increasing said threshold value when said possibility is determined to be high, wherein said threshold changer determines that said possibility is high when said terminal itself is inside a predetermined area, and determines that said possibility is low when said terminal itself is outside said predetermined area. - View Dependent Claims (7, 8, 9)

6. A controlling method of a mobile terminal shifting a state between a restricted state for restricting a key operation and an unrestricted state for making a key operation unrestricted, comprising:
-
a first selecting step for selecting said unrestricted state when a PIN code is input by a code inputting operation in a first restricted state for restricting a key operation so as to not perform a function associated with the key operation, excluding at least the code inputting operation; a second selecting step for determining whether a number of unsuccessful code inputting operations in said first restricted state is above a threshold value, selecting said first restricted state when it is determined that the number of unsuccessful code inputting operations is not above the threshold value, and selecting a second restricted state for restricting a key operation including at least the code inputting operation when it is determined that the number of unsuccessful code inputting operations is above the threshold value; a communication step for executing a short range radio communication with an external communication device; and a threshold changing step for determining a possibility of a key operator being a qualified person and increasing said threshold value when said possibility is determined to be high, wherein said threshold changer determines that said possibility is high when said terminal itself is inside a predetermined area, and determines that said possibility is low when said terminal itself is outside said predetermined area. - View Dependent Claims (10, 11, 12)
