Foldable type portable information terminal, answer holding method used in the same and program therefor

An answer holding method of a foldable type portable information terminal including 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 said upper unit for opening and closing and for pivoting, comprising:

• detecting step of detecting change of relative attitude between said upper unit and said lower unit;
• and
• control step of setting answer holding state when displacement of said upper unit to a preliminarily set first position is detected upon call incoming.
