Patent Images
1. A door videophone capable of rotating a camera, comprising:
- a main body having a monitor for displaying an image of a caller, and being located indoors;
a bell box having the camera for photographing looks of the caller and transmitting the image of the caller to the monitor, and being located outdoors;
an actuating means for rotating the camera, and being disposed in the bell box, wherein the actuating means includes;
a base plate for supporting the camera;
at least one driving means for generating a rotation force; and
at least one rotation force transmitting means for transmitting the rotation force generated by the driving means to the base plate, and being respectively connected to the driving means, wherein the driving means includes;
at least one first driving motor for rotating the base plate upward and downward as to an operation control signal; and
at least one second driving motor for rotating the base plate left and right as to the operation control signal; and
a control means for generating the operation control signal associated with the actuating means, and being disposed at the main body, wherein the door videophone has one first and second driving motors capable of rotating clockwise and counterclockwise, wherein the first and second driving motors are spaced out substantially 90 degrees, wherein the base plate includes a convex peripheral surface having a predetermined curvature and a pair of rails respectively facing with the rotation force transmitting means, and wherein the rotation force transmitting means respectively includes a first and second guide blocks having a groove, wherein the groove has a width substantially equal to that of each of the rails and a predetermined length.
