Claim:
1. A sheet material detaching device for stripping off a sheet material bonded to a base, the device comprising: a device main body; a winding roller that is provided on the device main body so as to be in contact with the sheet material and on which is wound the sheet material that is stripped from the base from a point of contact with the sheet material; a driving means that, by rotationally driving the winding roller, strips the sheet material from the base, and advances the device main body in a traveling direction by pushing the winding roller against the base by a stripping reactive force and rolling the winding roller on the sheet material; a cutter that is provided on the device main body and positioned on each lateral side of the winding roller for cutting the sheet material stripped from the base; and a scraping plate that extends from a rear side of the traveling direction of the device main body to a lower side of the winding roller is attached to the device main body, the scraping plate being inserted into a point of detachment between the sheet member, which is stripped from the base, and the base, to thereby facilitate detachment of the sheet material being wound up from the base by the winding roller, wherein the scraping plate is attached to the device main body such that, when the sheet member bonded to the base is in contact with the winding roller, a leading end of the scraping plate is flexibly pushed against the base.
