  • Patent number: 7555322
    Abstract: A foldable type portable information terminal can accurately recognize operation mode in a construction having various of functions and various relative attitudes. The portable information terminal includes the upper unit having the display screen in either of the upper or lower surfaces and the lower unit having the operation surface in either upper or lower surfaces coupled for opening and closing and for pivoting. The portable information terminal has a detector which detects variation of relative attitude of the upper unit and the lower unit, for externally announcing variation of relative attitude of the upper unit and the lower unit as detected by the detector.

  • Publication number: 20040203531
    Abstract: A foldable type portable information terminal, an answer holding method and a program therefor can set and release answer holding with simple operation. The foldable type portable information terminal includes an upper unit having a display screen on one of upper and lower surfaces and a lower unit having an operation surface on one of upper and lower surfaces, and coupled with the upper unit for opening and closing and for pivoting. The terminal further includes a detector detecting change of relative attitude between the upper unit and the lower unit, and a controller setting answer holding state when the detector detects displacement of the upper unit to a preliminarily set first position upon call incoming.
