<p>The projector has a light gate mechanism (13) including two rotating light gates (130D, 130G) for producing two different light beams. A mechanical indexing unit e.g. trigger stop (133), of the mechanism indexes a rest position of the mechanism. An actuator (131) rotates the light gates according to two rotation directions. The stop (133) determines an angular stop position of the light gate rotation.</p> |
