Patent ID: 8159593

Claim:
A display apparatus comprising: an apparatus body; a display unit that displays an image on a display screen; a hinge unit that couples the display unit to the apparatus body rotatably around first and second rotation axes along different directions; a single detection object arranged at a position near the first and second rotation axes but deviated from the first and second rotation axes, and to remain fixed in position with respect to the apparatus body when the display unit is rotated around the second rotation axis; an open/close detection sensor provided in one of the display unit and the apparatus body at a position deviated from the first rotation axis, the open/close detection sensor detecting an open/close state of the display unit around the first rotation axis in accordance with a positional relationship relative to the detection object, the display unit being opened or closed by being rotated with respect to the apparatus body; and an inversion detection sensor provided in the other of the display unit and the apparatus body at a position deviated from the second rotation axis, the inversion detection sensor detecting, when the display unit is closed with respect to the apparatus body, whether an inversion state of the display unit is a non-inverted state, in which the display screen of the display unit faces the apparatus body, or an inverted state, in which the display screen faces a side opposite to the apparatus body, with respect to the apparatus body around the second rotation axis in accordance with a positional relationship relative to the detection object.
