Abstract (en)
[origin: WO2014106655A1] The invention relates to a pen-shaped handheld instrument (1) for processing a substratum (4, 5), in particular a sheet of paper, comprising at least one pen tip (3), a shaft (17), and at least one optical sensor (2), by means of which at least one detection region (13) of the substratum (4, 5) and/or of a surrounding region (20) of the substratum (4, 5) can be optically detected, wherein the pen tip (3) is in contact with the substratum (4, 5) in a working position of the handheld instrument (1). According to the invention, in order to produce a handheld instrument by means of which a change of the substratum can be registered without the user of the handheld instrument being dependent on a special substratum or other aids except for the handheld instrument itself, the at least one optical sensor (2) detects an image angle (a) of at least 90°, preferably at least 100°, more preferably at least 110°. The invention further relates to an associated method for digitizing an impression produced by hand.
