Abstract

PURPOSE:To confirm a visitor's face in an optional room at the inside of the door by utilizing the indoor light even at night, by constituting a light irradiation body and a picture transmission body of an optical fiber. CONSTITUTION:An optical transmission body 1 is constituted of a light irradiation body 2 and a picture transmission body 3, using an optical fiber flux, and its one terminal B is positioned at the outside of the door, and the other terminal A is positioned at a suitable place in the room. A condensing body 4 and a diffusion plate 5 are provided on one terminal of the light irradiation body 2 and the other terminal, respedtively, and a light beam of the indoor side is transmitted and lights up the outside of the door. A wide angle lens 7 and an image receiver 6 are provided on one terminal of the picture transmission body 3 and the other terminal, respectively, and an image of the outside of the door is transmitted to the inside of the door. A calling device 10 sounds a whistle of an indoor device 12 when a visitor pushes a push- pump of an outdoor device 11, and presses air of a vent pipt 13, and also when the push-pump and the whistle are detected, the vent pipt is used for talking as a voice tube.
