Abstract: An automatic jigging device is described that utilizes a cam to move a fishing rod upwardly and downwardly in a manner based on fish behavior and psychology for a particular type of fish to increase the probability that a fish of the prescribed type will bite. Embodiments of a fishing rod holder are also described that can be used with the automatic jiggers or separately. The holder is adapted to lockably retain a fishing rod therein without the use of additional pieces.

Abstract: A beam separating prism system for an imaging system having two pairs of prisms, each prism having a 30, 60, and 90 degree triangular cross section and being provided with a partially reflecting region situated between the common boundary of the pair. A nonreflecting entry surface of one pair receives light which is both not focused and not parallel as reflected from a document. The light received at the entry surface is separated into three light components by the prism system. The exit axes of two light components are parallel and the exit axis of the third light component is at an angle of approximately 60 degrees to the other exit axes. The light is received by the pair of prisms having the entry surface and intercepted by the partially reflecting region of the pair. The remaining light is transmitted by the partially reflecting region to form a first component which is then reflected along an exit axis.
