PURPOSE: To provide a mobile phone that can enter analog data. CONSTITUTION: An antenna position detection circuit 17 detects a position of an antenna 16 moved vertically in response to an operation of a user and provides an output of an analog voltage denoting the detected position to an analog/digital converter 26. The analog/digital converter 26 converts the analog voltage into digital data and provides an output of the digital data to a CPU 11 via a bus line B. The CPU 11 conducts various processing items on the basis of output data from the analog/digital converter. For example, the CPU 11 conducts control of a tone volume of a voice output and a ringer tone, control of rolling speed of an address directory, or detection of a musical interval on the basis of a delicate input of the musical interval in the case of composing a ringer melody or the like. |
