Claims

[Scope of Claim for Utility Model Registration] (1) A door intercom sub unit with a camera configured to reflect incident light from an entrance window of the intercom sub unit on a reflector and input it to a camera imaging unit, which includes the above-mentioned The reflector is made of a material that can be bent and deformed, and is equipped with a pressing piece at the tip that operates in response to an operation from the main unit of the intercom with monitor TV that is used in conjunction with the door phone slave unit. 1. A camera-equipped door intercom slave unit, characterized in that the field of view incident on the camera imaging section changes by changing the field of view into the camera imaging section by causing unevenness to be deformed by driving the field of view adjustment means. (2) The camera-equipped intercom slave device according to claim 1, wherein the reflecting plate is configured such that a side surface of the camera imaging section is deformed into a convex shape by driving the input field of view adjusting means. (3) The camera-equipped intercom slave unit according to claim 1, wherein the reflecting plate is configured such that a side surface of the camera imaging section is deformed concavely by driving the input field of view adjusting means. (4) The camera-equipped intercom slave device according to claim 1, wherein the reflecting plate is configured such that the side surface of the camera imaging section is deformed into concave and convex shapes by driving the input field of view adjusting means. .
