PROBLEM TO BE SOLVED: To position paper in a curved state and to reliably position the paper even in a side curled state by providing positioning restraining means of the paper on a curved path. SOLUTION: The paper entering from an image device main body is inverted by an inversion roller 201 and is stored in an intermediate tray 202, the inversion roller 201 is inverted with pressure rollers 204 kept unreleased, and the paper is delivered in the re-feeding direction (direction of an arrow (c)). The pressure rollers 204 are released when the paper strides over the inversion roller 201, and the inversion of the paper is stopped. Restraining members 206 are jogged, the pressure rollers 204 are again pressed, both side edges of the paper is guided by guide sections 206a and inversion guide members 207, and the paper is conveyed in the re-feeding direction. Even when the paper is kept in a curved state, the curl at both side edges can be corrected by the inversion roller 201 and the guide sections 206a and inversion guide members 207 of the restraining members 206.
