Patent ID: 8016432

Claim:
A projection apparatus, adapted to be disposed on a surface and adapted to project an image frame onto the surface, the projection apparatus comprising: a housing; an optical engine, disposed in the housing and capable of providing an image beam; a projection lens, disposed in the transmission path of the image beam, wherein the housing is capable of exposing a part of the projection lens; a containing sink, disposed on the housing, and having a containing space; an extension rod, movably connected to the containing sink; and a curved surface reflection device, pivotally connected to the extension rod, wherein the extension rod and the curved surface reflection device are adapted to be contained in the containing space, and the extension rod is capable of moving with respect to the containing sink so as to protrude out of the containing space, when the extension rod is capable of protruding out of the containing space, the curved surface reflection device is adapted to be rotated to the transmission path of the image beam, and the curved surface reflection device has a curved reflective surface capable of reflecting the image beam to the surface to form the image frame.
