IMAGE PICKUP APPARATUS

An image pickup apparatus has a casing; a camera unit configured to be disposed in the casing and hold a lens; a protecting member configured to protect the camera unit; and a holding member configured to hold the protecting member and to be rotatably held to the casing around a shaft serving as a central axis. The holding member is rotatable between a first position at which the protecting member is fixed to the casing and a second position at which the protecting member is attachable to and detachable from the casing.
