Electronic apparatus and method for detecting the value of voltage supplied by a power source during the operation of an input and/or output device on the basis of test data sent to the input and/or output device

摘要

An electronic apparatus and method includes a memory for storing data to be sent to an input and/or output device, a transmitter for transmitting data stored in the memory, a power source for supplying power to the input and/or output device, a device for outputting predetermined test data to the input and/or output device, a detector for detecting the value of the voltage supplied by the power source during operation of the input and/or output device on the basis of the predetermined test data, and a determining device for determining whether the voltage detected by the detector is higher than a predetermined voltage. The data stored in the memory is sent to the input and/or output device when the voltage detected by the detector is determined to be higher than the predetermined voltage.
