Abstract: A laser light source device of the present invention is disclosed. More specifically, the present invention relates to a laser light source device for emitting a deflected light so as to form a specific shape by outputting a laser beam through a point light source, and a parking indicator light system including the same. According to an embodiment of the present invention, an indicating line according to a road shape is projected and displayed on a road surface within an underground parking lot such that a driver may easily recognize traveling and parking directions of a vehicle on a road with a limited road width, narrow view, and dim illumination.

Abstract: An apparatus for rotationally adjusting a cam, that includes an adjustment pinion having a number of missing teeth that couple to an integral gear formed on a rotatable cam. The adjustment pinion is used to manually adjust the angular position of the rotatable cam relative to the rotatable cam's axis of rotation. When the missing teeth of the adjustment pinion disengage from the gear integral to the cam, rotation of the adjustment pinion ceases. The adjustment apparatus may be readily incorporated into a programmer/timer.
