PROBLEM TO BE SOLVED: To allocate high-level operation to an antenna of a mobile phone. SOLUTION: The antenna 50 is held slidably between a draw-out position where the antenna is drawn out of a storage cylinder formed in an upper unit 12 and a draw-out position where the antenna is drew-out in the storage cylinder 60, and when the antenna 50 is moved to the storage position, a cam 70 formed on the antenna 50 engages a gear 72 of the storage cylinder 60. In this state, the antenna 50 is rotated and then the gear 72 rotates as the cam 70 rotates, so that a variable resistor 74 connected to the gear 72 varies in resistance value. A control section 34 moves a zoom lens 32 to a position corresponding to the resistance value. Consequently, zoom power during photography can be varied by rotating the antenna 50.
