Next, the operation of this embodiment will be described with reference to the drawings. In FIG. 1, when the print medium 1 is inserted in the direction of arrow A, the feed roller 3 holds the print medium 1 and conveys it to the position of the line sensor 9 at a constant speed v. At this time, the front end of the print medium 1 passes through the photosensors 7 and 8, but the positions of the photosensor 7 and the photosensor 8 are provided in the print medium suction direction, that is, on a line forming an angle with the arrow A direction. Therefore, if the deviation Δt of the timing at which each sensor operates is measured, the skew amount δ (see FIG. 2) becomes δ
= V × Δt. Therefore, from FIG. 2, the inclination θ of the print medium is θ = tan −1 (δ / a). Further, since the length L in the direction perpendicular to the print medium suction direction is determined by the output of the line sensor 9, the actual print medium 1
The width dimension D of is obtained from FIG. 3 as D = Lcos θ.
