A portable terminal apparatus which can select terminal operations such as the activation of programs, the switching of the programs and the ending of the programs with a reduced number of times of operation of the operation buttons is provided. Then, an insulation film is formed on the plug and barrier film, and a hole is made in the insulation film such that an upper surface of the plug is exposed. The terminal connector includes a terminal engaging member, integrally comprising a shaft portion and an engaging portion. The selection switching section extracts the counter electromotive voltage of the brushless motor, feeds the voltage back to the DC motor driving integrated circuit and PWM controls a drive signal output from the three-phase brushless motor driving integrated circuit. The first groove is configured to receive the rib in a state in which the supporting portion supports the wall.
