On-vehicle display device

A selectively mountable display apparatus suitable for mounting on a supporting base attached to a surface, said apparatus comprising:

• a cabinet containing a media presentation device, said cabinet being separate from said supporting base such that said cabinet must be combined with said supporting base in order to mount said apparatus to said surface;
• a mounting device disposed in said cabinet for combining said cabinet with said supporting base, said mounting device comprising an axial member disposed in said cabinet such that said cabinet may be mounted at a plurality of rotational orientations with respect to said supporting base, using said axial member as an axis of rotation;
• and
• an operating mechanical unit disposed in said cabinet for establishing or cancelling the combination of said cabinet and said base wherein said operating mechanical unit connects said cabinet to said base using said axial member by inserting or retracting a protruding portion of said axial member disposed in said cabinet to and from said base such that said protruding portion is inserted into said base along the same line where said axial member is disposed, and such that the connection of said protruding member and said base facilitates rotation of said cabinet with respect to said base about said axial member,
• wherein said display apparatus comprises a plurality of cabinets, each of which is said cabinet.

• and
• an attitude setting unit disposed in said cabinet for, when said cabinet is combined with said base, allowing for the determination of a rotational attitude of said cabinet with respect to said base for a plurality of positions such that a plurality of fixed positions are set within the rotational range of said cabinet with respect to said base wherein said cabinet may be mounted to said base in any of said fixed positions and may be rotated between said fixed positions while mounted to said base, said attitude setting mechanical unit further comprising a retractable convex portion protruding from the outer surface of said axial member.
