1. a mobile terminal device, comprising:

  • Movable part, it has display part;

    Arm, it is arranged on a base portion, this arm portion configuration for supporting this movable part, to make this movable part can around a center of rotation rotating relative at least slewing area of+90 °

    of center position;

    AndPosition detection part, it is configured to detect the turned position of this movable part relative to this arm;

    Wherein, this position detection part comprises;

    a pair reflector, and it has different reflection characteristics;

    Photoelectric sensor, it to be configured to light to be transmitted on described reflector and to detect the light from described reflector reflects;

    And calculating part, it is configured to the turned position determining this movable part based on the output of this photoelectric sensor;

    Described reflector is arranged in this arm or this movable part, is separated from each other 180 °

    to make described a pair reflector around this center of rotation;

    If described reflector is arranged in this arm, then this photoelectric sensor is arranged in this movable part, if or described reflector be arranged in this movable part, then this photoelectric sensor is arranged in this base portion;

    AndThe first reflector in described reflector responds this movable part and leaves+90 °

    of this center position and to rotate and relative with this photoelectric sensor, and the second reflector in described reflector responds this movable part leaves-90 °

    of rotations of this center position and relative with this photoelectric sensor.
