Abstract: According to an aspect of an embodiment, an apparatus includes: a connector for connecting a removable device; a first detector for detecting a change of a signal indicative of a state of a connection between the removable device and the connector; a second detector for detecting acceleration applied to apparatus; and a controller for determining the state of the connection between the removable device and the connector upon detecting the change of the signal and the information of the acceleration.

Abstract: A reader/writer module for IC cards, employing a magnetic sheet that suppresses the interference with a metallic member yet reduced in thickness. A reader/writer for non-contact IC cards or the reader/writer module for IC cards equipped with the reader/writer for non-contact IC cards, is incorporated in a housing of an electronic equipment. A magnetic sheet is secured to a predetermined region on one surface of the module substrate, a loop antenna is arranged on the magnetic sheet, and a circuit component connected to the loop antenna is mounted on a region outside the magnetic sheet of the module substrate.

Abstract: To prevent original data as a write target data from being destructed in the case of writing the data to a recording medium. An information processing device that writes data to an attachable/detachable recording medium includes data segmenting unit segmenting the data, data writing unit writing the data segmented by the data segmenting unit to the recording medium, and detecting unit detecting ejection of the attached recording medium, wherein the data writing unit stops writing when the detecting unit detects the ejection of the recording medium.
