Abstract
A vertically extensible and retractible lens arm for a camera includes a plurality of hollow telescoping sections that slide one within another. A lens for taking a picture is connected to a top telescoping section. Each telescoping section except the top one has a generally semicircular hollow space that becomes narrower toward a bottom of the telescoping section and is adapted to receive the lens therein when the lens arm is retracted. The top telescoping section can be provided with only a projecting part at the outside of the lower portion of each of opposite side walls whereas each telescoping section except the top one can be provided both with a notch at the inside of the upper portion of each of opposite side walls and with a projecting part at the outside of the lower portion of each of the opposite side walls.
