A power transmission apparatus and a rotation apparatus are disclosed. A power transmission apparatus that includes: a power generating part, which includes a drive axis; a worm, which is joined to the drive axis; a worm gear, which meshes with the worm, and which includes an output axis configured to transmit power; and a friction hinge, which is joined to the output axis, and which is configured to engage and disengage a rotational force of the output axis, can provide sufficiently high deceleration and high torque, even when a low-capacity motor having a low cogging torque is used. Also, the power transmission apparatus can be made safer and less noisy for not only automatic operation by the motor but also manual operation by a user, while the gear module, motor, etch, can be protected from excessive loads.

A tilting device for repeatedly tilting light reflected from a micro-mirror panel is disclosed. A vibration type tilting device, comprising a mirror positioned on a light path which reflects light transmitted from a digital micro-mirror panel, a mirror holder having the mirror joined to a side thereof, a coil joined to the reverse side of the mirror holder, and a magnet which generates a magnetic field passing through the coil, where portions of the mirror holder are removed to decrease the mass moment of inertia of the mirror holder, may not only provide a smooth and natural display by periodically tilting light reflected from a digital micro-mirror panel in constant time intervals but also may improve the tracking ability of the mirror and reduce residual vibration.

A tilting device is disclosed which tilts the light reflected from a Digital Micro-mirror device by a certain angle and projects it to a screen. The tilting device, comprising a first reflector surface, a second reflector surface inclined at a predetermined angle with regard to the first reflector surface, a holder attached to the bottom of the first reflector surface and the second reflector surface, and a driving part that provides rotational force to the holder, wherein the first reflector surface and the second reflector surface are rotated by the driving part to sequentially reflect light emitted from a Digital Micro-mirror device, not only provides a smooth and natural display with invisible grids but also allows more stable and more accurate tilting.
