Patent ID: 8593294

Claim:
A data transfer apparatus, which has a wireless communication processing part providing a wireless communication function and a memory, comprising: an acceleration sensor; a buzzer; and a control part which detects a user's operation based on acceleration information output from the acceleration sensor and, based on the detection result, determines whether or not a file management operation including access to the memory is started and whether or not the buzzer is rung, wherein the file management operation includes a file sending processing of sending a file to another data transfer apparatus by utilizing the wireless communication function and a file receiving processing of receiving a file from another data transfer apparatus by utilizing the wireless communication function, and a plurality of acceleration patterns as start triggers of the file sending processing and a plurality of acceleration patterns as start triggers of the file receiving processing are specified, and when the control part controls the buzzer in a case where the file sending processing of sending a file to another data transfer apparatus is started, the control part rings the buzzer so that the ringing pattern of the buzzer coincides with any one of the specified acceleration patterns as the start triggers of the file receiving processing.
