Television camera device for watching purpose
First Claim
1. Television camera device for watching purpose comprising a casing supported by a supporting post in position in a space to be watched by said television camera device, said casing consisting of a first portion fixedly secured to said supporting post and a second portion rotatably mounted on said first portion by a pivot shaft secured to said second portion and extending into said first portion so as to be rotated with respect to said first portion, a television camera mounted in said second portion of said casing with its picture taking lens directed to the desired direction in said space through an opening formed in said second portion thereby permitting said camera to be operated to watch the desired sight in said space while it is hidden in said second portion, an electric motor mounted in said casing and energized by an electric source, motion transmitting means located in said second portion of said casing and interconnecting said electric motor and said pivot shaft secured to said second portion of said casing thereby permitting said pivot shaft and, hence, said second portion of said casing to be rotated with respect to said first portion of said casing by the actuation of said electric motor wherein said motion transmitting means comprises a driving plate with its proximal end secured to the shaft of said electric motor, a connecting plate with its one end pivotally connected to the distal end of said driving plate and a follower plate with its proximal end secured to said pivot shaft while the distal end thereof is pivotally connected to the opposite end of said connecting plate, thereby permitting said second portion of said casing to be reciprocally rotated together with said television camera while said electric motor is continuously driven.
