Abstract:
1. An imaging unit including an incident optical axis, an intermediate optical axis, and a reflecting surface, wherein light incident on said incident optical axis is deflected by said reflecting surface and is directed along said intermediate optical axis, and wherein a first lens group and a second lens group are disposed along said intermediate optical axis, said imaging unit comprising: a first guide bar configured to guide a first lens group frame holding said first lens group; a second guide bar configured to guide a second lens group frame holding said second lens group; a first actuator having a first drive shaft and configured to move said first lens group frame along said first guide bar; and a second actuator having a second drive shaft and configured to move said second lens group frame along said second guide bar; wherein said first guide bar and said second guide bar extend in a direction parallel to said intermediate optical axis, and are positioned on opposite sides of said intermediate optical axis when said first guide bar and said second guide bar are viewed from said incident optical axis, and wherein said first drive shaft and said second drive shaft extend in a direction parallel to said intermediate optical axis, and are positioned outside said first and second guide bars such that said first and second guide bars are positioned between said first and second drive shafts when said first and second drive shafts are viewed from a direction perpendicular to said intermediate optical axis.
