In a cellular phone, when a coming-to-the-office signal is detected by a non-contact IC section, a CPU selects an official mode as a telephone number mode. Meanwhile, when a leaving-the-office signal is detected by the non-contact IC section, the CPU selects a private mode as a telephone number mode. In an application menu, applications usable and not usable in the current telephone number mode are displayed according to the availability mode added for the applications so that a user can identify these applications. Only the file's corresponding with the current telephone number mode can be selected according to the mode identifier added for the file, or the type of the folder storing the file. Thereby, a plurality of processing functions included in the cellular phone, or many files stored therein can be automatically used selectively either on official use or on private use.
