To provide an image recorder capable of precisely positioning a sheet type medium to an exposure part by truing-up even when the size of the sheet type medium to be conveyed is changed.
The image recorder is equipped with; a conveyance means capable of conveying the sheet type media F1 to F3 of a plurality of sizes; an exposure means for forming a latent image by scanning the conveyed sheet type medium; and a correction means for correcting the position of the sheet type medium in a direction orthogonal to the conveyance direction thereof relative to scanning by the exposure means. The correction means has; at least a pair of conveyance rollers 4 conveying the sheet type medium toward the exposure means and capable of releasing press-fitting; a locking means 5 capable of releasing press-fitting, preventing the movement of the sheet type medium in the conveyance direction by gravity when press-fitting, and allowing the movement thereof in the direction orthogonal to the conveyance direction; and a pair of engaging members 1 and 2 capable of moving in the direction nearly orthogonal to the conveyance direction of the sheet type medium, engaged with both ends of the sheet type medium and correcting the position thereof in the direction orthogonal to the conveyance direction. The locking means 5 is provided at a position nearest to the exposure means in the correction means.
