A mobile station for an automobile telephone system comprises a main unit (1) and a telephone set (2) connected to the main unit, for instance, by a curl cord (3). The main unit includes a power supply (4) which is turned on from the telephone set, a controller (6) for controlling the power supply to be turned on and off in accordance with a control signal supplied from the telephone set, and a detecting circuit (16) for detecting the separation of the telephone set from the main unit. When the detecting circuit detects the separation of the telephone set from the main unit, the controller controls the power supply to be turned off, even if a power supply turning-off signal is not produced in the telephone set. |
