PROBLEM TO BE SOLVED: To provide an intercom device which reduces the depth of a case compared to conventional intercom devices without enlarging the entire case even if the intercom device incorporates a power transformer therein.SOLUTION: A power transformer 6 is placed in a lower part of a case 1 and a speech button 11 is placed on a front surface of the power transformer 6. A lower part of the speech button 11 is extended to an area below the power transformer 6. An upper case 1a is inclined rearward from a center part in both upper and lower directions to form a curved shape. Case thicknesses of upper and lower end parts are formed so as to be thinner than the center part. The upper case 1a located around the speech button 11 is disposed at the rear side of the speech button 11 to make upper and lower portions of the case thin. |
