Abstract
A handset device which includes a small magnet unit, is simple in construction, and yet ensures the magnetic holding of a handset and the outputting of an on-hook signal when it is hung up on a main body. The magnet unit is provided in one of a portion of the main body and a portion of the handset which face each other when the handset is hung up, while a magnetic material is provided in the other of those portions, so that a magnetic attracting force may occur between the magnet unit and the magnetic material. The magnetic material has a saturation magnetic flux density which is lower than that of the magnet unit, so that magnetic leakage may occur. A magnetic detector is provided for detecting such magnetic leakage and outputting the on-hook signal.
