<p>PROBLEM TO BE SOLVED: To securely regulate a stop position of a paper sheet in a reverse passage when the paper sheet is fed to the reverse passage for switch back, and to reduce the length dimension of a mechanism for regulating the stop position of the paper sheet in the reverse passage in a direction along the direction for feeding the paper sheet to the reverse passage. SOLUTION: As a member for regulating the stop position of the paper sheet fed to the reverse passage 19, a movable stopper 22 and a fixed stopper 23 are provided. In the case of regulating the stop position of the paper sheet having a size smaller than the longest size paper sheet possible to be used for an image forming device, the movable stopper 22 fitted to a belt 26 to be driven for rotation along the direction for putting the paper sheet in/off in relation to the reverse passage is used. In the case of regulating the stop position of the longest size paper sheet, the movable stopper 22 is moved to a waiting position, and the fixed stopper 23 is used.</p> |
