Abstract
A projection apparatus includes a light source, an optical engine module, and a lens module. The lens module includes a plate having at least one through hole, a lens fixed to the plate, at least one slide assembly disposed between the plate and an optical engine housing of the optical engine module, and a position adjusting device including a movable guide member and at least one guide pillar. The plate is movably disposed on the optical engine housing through the slide assembly. The movable guide member is movably disposed between the plate and the optical engine housing. The guide pillar is disposed on the movable guide member and passes through the through hole. When the movable guide member is forced to move towards an axial direction, the guide pillar drives the plate to move on the slide assembly along the axial direction relative to the optical engine housing.
