Abstract
A mobile terminal includes: a tamper-detection circuit (17), an information processor (13) that is capable of executing a suspend function, a first battery (23) supplying power to the information processor (13) and the tamper-detection circuit (17), and a switch (27) that is provided on a power-source supply line (431) that connects the first battery (23) and the information processor (13) and the switch that is capable of switching between a state in which information processor (13) is connected to first battery (23) and a state in which information processor (13) is not connected to first battery (23).
Claims2
A mobile terminal including a tamper-detection circuit, an information processor that is capable of executing a suspend function, a first battery supplying power to said information processor and said tamper-detection circuit, wherein the improvement comprises
- a switch provided in the power-source supply line that connects said first battery and said information processor and said switch being capable of switching between a state in which said information processor is connected to said first battery and a state in which said information processor is not connected to said first battery,
- wherein said tamper-detection circuit, when power is supplied to the tamper-detection circuit, maintains resistance to tampering regardless of whether or not power is supplied to said information processor,
- said switch is not provided in a power-source supply line that connects said first battery and said tamper-detection circuit, and
- said switch is a mechanical switch that allows an operator to manually switch between ON and OFF, and that allows the operator to confirm a state whether or not said suspend function is activated.
