<P>PROBLEM TO BE SOLVED: To detect opening/closing without disposing a dedicated component in a movable part in an electronic apparatus detecting the opening/closing of the movable part that is openably/closably provided with respect to a housing using a magnetic field. <P>SOLUTION: This electronic apparatus includes the housing and the movable part openably/closably provided with respect to the housing. The housing includes: a magnetic member disposed near the rotation center of the movable part; magnetic field detecting means for detecting a magnetic field; and determination means for determining the open/closed state of the movable part based on the detection result of the magnetic field detecting means. One end of the movable part includes a steel plate that is disposed near the rotation center of the movable part, the steel plate is magnetized by the magnetism of the magnetic member, and the magnetic field detecting means is disposed near the other end of the steel plate in a state where the movable part is closed to the housing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
