1. An intercom device comprising:
an entrance slave unit configured to call and talk from a visitor to a resident; and
a living room master device configured to respond to a call from the entrance slave unit,
wherein the entrance slave unit includes a touch operable aerial display configured to display an aerial image toward the visitor, a control unit configured to control the touch operable aerial display, and a sensor arranged in a predetermined space and capable of detecting a height of an eye level of the visitor,
wherein the touch operable aerial display includes a light source for emitting light to generate the aerial image, an optical member for reflecting and transmitting the light so as to form the aerial image in the predetermined space, and a detection unit for detecting an operation input of the visitor with respect to the aerial image, and
wherein, when the height detected by the sensor is equal to or lower than a predetermined threshold value, the control unit changes a display angle of the aerial image such that an upper side of the aerial image having a rectangular shape is inclined in a direction approaching the visitor than a lower side of the aerial image.
