PROBLEM TO BE SOLVED: To provide a technique capable of acquiring high accuracy handwriting information without using a special handwriting instrument when writing is performed on a form.SOLUTION: A handwriting information acquisition system 10A comprises: a handwriting acquisition liquid crystal panel part 103 which includes a detection area which detects a stress and changes from a transmission state transmitting light of a first wavelength range to a reflection state reflecting the light of the first wavelength range; an image acquisition part 107 which detects the light of the first wavelength range reflected by the detection area; and a handwriting acquisition light removal part 104 which absorbs the light of the first wavelength range. The handwriting acquisition light removal part 104 is provided opposite to the image acquisition part 107 with reference to the handwriting acquisition liquid crystal panel part 103. |
