Abstract
A communication device according to one aspect of embodiments includes a controller. In a case where vibration of the communication device is detected, the controller allows execution of a communication process with a communication target device.
Claims7
A communication device comprising:
- a processor programmed to:
- in a case where vibration of the communication device is detected, allow execution of a communication process with a communication target device;
- a vibration powered generator configured to:
- generate electric power by the vibration of the communication device;
- and
- supply electric power to the communication device, wherein
- the processor is further programmed to:
- detect the vibration based on a power generating state of the vibration powered generator and
- the communication device further comprises:
- a plurality of operation buttons that receives a user operation ordering execution of the communication process;
- an electric condenser that stores therein electric power generated by the vibration powered generator;
- and
- a cooperation switch that is turned into an ON state in response to an operation of the plurality of operation buttons to connect the vibration powered generator and the electric condenser to each other, and turns the electric condenser into a charge state, wherein
- electric power is supplied from the electric condenser to the communication device.
