Abstract:
To provide an intercom device capable of suppressing the generation of ghosts and flares.SOLUTION: A surface of a front face portion 20a of a camera holder 15 is formed as a surface that protrudes forward in an arc shape from a peripheral edge of a lens hole 20c to an outer edge of the front face portion 20a, and that slopes linearly backward from a point beyond a tip. An arc-shaped portion is composed of a first R-surface 21 with a radius of 1.0 mm located in an inner radial direction and a second R-surface 22 with a radius of 0.5 mm, which is an R-surface with a smaller radius than the first R-surface 21 and continuously widens outward in the radial direction from the first R-surface 21.SELECTED DRAWING: Figure 6
