Abstract
A housing for a TV camera has an automatic wiping mode for automatically driving a wiper, which is provided at a front window of the housing, at predetermined time intervals. The execution of the automatic wiping mode while the TV camera is unused prevents a large amount of snow and frost, etc. from adhering to the front window. The wiper and two nozzles of a window-washing device for jetting a washing liquid are provided on the front window of the housing in a pan/tilt head. If the pan/tilt head is set to the automatic wiping mode, the wiper and the window-washing device automatically operate at predetermined time intervals. This prevents the snow and the frost from adhering to the front window while the pan/tilt head is not operated, e.g., at night. Thus, the shooting can be begun quickly when the need arises.
