Abstract
A video camera unit is separated into a holder for receiving lenses and a base on which a solid-state image pickup chip is mounted. The holder and the base are assembled together with the distance between them made variable so that it is possible to adjust the back focus of the lens. Further, a video camera unit has a holder which is separated into a first holder for receiving lenses and a second holder for receiving a solid-state image pickup device so that both holders can be assembled together with the distance between them made variable. Therefore, it is also possible to adjust the back focus of the lens.
