In an imaging device, as a baseis moved from a certain position on an upper side of an imaging area SA to a different position on a left side of the imaging area SA, a camera headis pivotally rotated together with a head-side armrelative to a second arm. Such combination of the movement of the basewith the pivotal rotation of the camera headchanges the operation mode of the imaging devicefrom a first working mode to a second working mode and enables the imaging deviceto take images in the second working mode. Regardless of the positional change of the basefrom the position on the upper side of the imaging area SA to the position on the left side of the imaging area SA with the change of the operation mode of the imaging devicefrom the first working mode to the second working mode, an up-down positional relation in an imaging view field of an internal camera, which is incorporated in the camera headand is operated to shoot downward and take an image of a shooting object sheet ST set in the imaging area SA, is kept unchanged relative to the shooting object sheet ST.

A zoom dial mechanism includes a zoom dial mounted on a base plate so as to extend through a central hole of the base plate and so as to be turnable, a coil spring mounted on the base plate to urge the zoom dial toward a neutral position, and a push knob mounted in a central hole of the dial. The base plate has a groove concentric with the central hole. The coil spring is mounted in the groove. The mechanism further includes a first rib fixed to the dial so as to abut one end of the coil spring and a second rib fixed to the dial so as to abut the other end of the spring. The spring is compressed by the first rib when the dial is turned clockwise, and the coil spring is compressed by the second rib when the dial is turned counterclockwise.

A monitoring camera includes a camera housing, a camera body housed in the camera housing, a lens barrel protruding from the camera housing, and a lens housing mounted for protecting the lens barrel. The lens housing is detachably mounted on the camera housing by bayonet engagement.

A casing for encasing equipment installed outdoors, such as a monitoring camera, includes a bottom having a drain hole formed through the bottom. The drain hole includes a first part and a second part having a larger inner diameter than the first part. The second part is open at an underside of the casing.

To set a distance between a lens mounting surface of a lens mount and a image pickup element for a back-focus of a interchangeable lens, the video camera comprises two guide pins fixed inside a front panel of a camera body parallel to an optical axis of a lens, said front panel which the lens mount is fixed in, a carrier supported by the two guide pins to move parallel to the optical axis, said carrier to which the image pickup element is fixed, a spring provided between the carrier and the front panel of the camera body to bias the carrier in such a direction that the carrier separates from the lens mount, a screw shaft rotatably assembled on the camera body by a holder to move parallel to the optical axis of the lens, said screw shaft having one end connected with the carrier and the other end on which an adjusting ring is screwed, and an opening formed in the camera body. When the ring is rotated by a finger or a tool being inserted in the camera body through the opening, the screw shaft moves back and forth, so that the carrier moves parallel to the optical axis of the lens along the guide pins. As a result, a change occurs in The distance between a lens mounting surface of the lens mount and the image pickup element.
