Abstract:
1. A projection device, comprising: a first optical component; a second optical component configured to be disposed adjacent to the first component defining an optical path, wherein the second component is movable relative to the first component: a latch mechanism coupled to the second component and configured to enable a user to manually couple the second component to the first component and to manually release the second component from the first component; and an alignment system; wherein the latch mechanism and the alignment system are configured to cooperatively and releasably couple the second component to the first component in a predetermined orientation; and wherein the latch mechanism comprises: a keeper coupled to the first component; a base coupled to the second component; a coupling arm pivotally coupled to the base, having a latched orientation and an unlatched orientation, and configured to couple with the keeper when in the latched orientation; and an actuating lever operatively associated with the coupling arm to transition the coupling arm between the latched orientation and the unlatched orientation.
