PURPOSE:To transmit a signal from a mobile station to a base station with high reliability by generating an alarm at the time when necessity for drawing out an antenna is generated and urging a user so as to draw out the antenna. CONSTITUTION:A mobile machine is provided with an operating part 12, a voice input/output part 13, an alarm generating part 14, a control part 15 and a transmitting/receiving part 16, and to this transmitting/receiving part 16, an antenna 11 is attached, and the alarm generating part 14 generates an alarm by a sound, light, vibration, etc. In such a state, in the case an answer signal cannot be received, whether the antenna is stored or not is decided, and in the case of a drawn-out state that it is not stored, it is decided that a result of signal transmission is a failure and a conventional and regular processing is executed. In the case the antenna is stored, the alarm generating part 14 is allowed to generate an alarm by a sound, light, vibration and others which can be detected by a user. Also, in the case the user draws out the antenna, the same signal is sent out again to the base station. |
