#1. Field of the Invention

#The present invention relates to a rotation device with an integral bearing that is for use in various machinery and electronic equipments including surveillance cameras.

#2. Description of the Related Art

#The above and other objects and features of the invention will appear more fully hereinafter from a consideration of the following description taken in connection with the accompanying drawings wherein examples are illustrated by way of example, in which:

#FIG. 1 is a perspective view of a conventional surveillance camera;

#FIG. 2 is a configuration diagram showing an example of a surveillance camera comprising a rotation device with an integral bearing according to an embodiment of the present invention;

#An embodiment of the present invention will be described below with reference to the accompanying drawings now.

#FIG. 2 is a configuration diagram showing an example of a surveillance camera comprising a rotation device with an integral bearing according to an embodiment of the invention. This surveillance camera 1 comprises camera 3 that performs the recording, and rotation device 2 that enables the camera to rotate so as to change the camera's recording direction. Moreover, rotation device 2 consists chiefly of horizontal rotation mechanism 4 and vertical rotation mechanism 5.

#Referring to FIG. 2, power source 6 is of a plastic cylinder and secured to ceiling C. Fixer 7 that supports rotation device 2 is of a plastic cylinder and detachably mounted to power source 6. Dome cover 8 is of transparent plastic and secured to fixer 7. These constitute the outer ward of surveillance camera 1. Power circuit board 9 positioned inside power source 6, has a power circuit that is connected to a power source, both not illustrated, and a coaxial cable, not illustrated, for outputting image signals and inputting control signals from the monitors. Fixer 7 and base plate 10 of rotation device 2 are connected, and base plate 10 supports horizontal rotation mechanism 4. Vertical rotation mechanism 5 is rotatably connected to horizontal rotation mechanism 4 via bearing 11, and camera 3 is mounted to vertical rotation mechanism 5.
