In various embodiments, a lens array comprises a plurality of aspheric lens elements each optically coupled to a light-emitting element and producing an out-of-focus image thereof. A guide piece 14, which is a part of first lever member 10 arranged on first side of the base B, is formed being located on a second side of the base B. The control device includes rotation direction determination means for determining a rotation direction of an output shaft of an automatic shifting portion based on an engagement of a given coupling element and a detected result of rotation direction detection means.
