Mobile information terminal executing application program
First Claim
1. A mobile information terminal comprising:
- a controlling portion configured to execute an application program; and
a resetting portion configured to output a resetting signal for rebooting said controlling portion in a case where a predetermined operation by a user is accepted, wherein;
said controlling portion includes a determining portion to determine whether an audible security sound emitted by the mobile information terminal is activated to indicate a condition when resetting said controlling portion is not permitted, and a state-signal outputting portion to output a state signal denoting either a resettable state or a non-resettable state of said controlling portion, wherein said state-signal outputting portion outputs the state signal denoting the non-resettable state in a case where the determining portion determines that the audible security sound is activated, after the state signal denoting the resettable state is output; and
said resetting portion includes a judging portion to output to said controlling portion said resetting signal on condition that said state signal denotes the resettable state of said controlling portion.

Abstract
In order to control the resetting operation, a mobile phone is provided with a CPU capable of executing an application program, a power switch to receive an instruction for switching power between the ON state and the OFF state, and a reset detecting circuit to output a resetting signal for rebooting the CPU when the power switch is closed for a predetermined period of time. The CPU outputs a state signal denoting either a resettable state or a non-resettable state of the CPU. The reset detecting circuit includes an AND element to output to a resetting circuit a high signal (resetting signal) on condition that the state signal denotes the state of the CPU as resettable. The resetting circuit outputs to the CPU a low signal (resetting signal) upon input of the high signal (resetting signal) from the reset detecting circuit.

12. A mobile information terminal comprising:
-
a controlling portion configured to execute an application program; and a resetting portion to reboot said controlling portion in the case where a predetermined operation by a user is accepted, wherein; said controlling portion includes a determining portion to determine whether an audible security sound emitted by the mobile information terminal is activated to indicate a condition when resetting said controlling portion is not permitted, and a state-signal outputting portion to output a state signal denoting either a stoppable executing state or an unstoppable executing state of said controlling portion, wherein said state-signal outputting portion outputs the state signal denoting the non-resettable state in the case where the determining portion determines that the audible security sound is activated, after the state signal denoting the resettable state is output; and said resetting portion avoids rebooting of said controlling portion in the unstoppable executing state of said controlling portion in the case where the predetermined operation by the user is accepted. - View Dependent Claims (14)
