Abstract

A handwritten-information processing apparatus includes a handwritten-information acquisition unit and a handwritten-information insertion unit. The handwritten-information acquisition unit acquires a handwritten information item which has been handwritten by a user on a medium having a region inside a writing frame and a region outside the writing frame. The region inside the writing frame includes division regions. The region outside the writing frame is located outside the region inside the writing frame. When the handwritten-information acquisition unit has acquired an insertion mark which is a handwritten information item extending across a boundary between the region inside the writing frame and the region outside the writing frame, the handwritten-information insertion unit inserts, on the basis of the insertion mark, into the region inside the writing frame, a handwritten information item which has been handwritten in the region outside the writing frame.
