<p>PURPOSE:To prevent surely the intrusion of an outside foreign object from a paper feed opening or a paper discharge opening to the inside of a device main body at the time of the non delivery of a sheet material, by making a paper feed stand changeable to the 1st and 2nd posture positions, and making this paper feed stand function as a blockading door, when it is at the 2nd posture position, covering the paper feed opening and either one of the 1st and 2nd paper discharge openings. CONSTITUTION:When the delivery of a sheet material to the inside of a device main body by using a paper feed opening 18 is not conducted, or when the device is not used or is transported, a paper feed stand 22 which is at the 1st posture position, is changed to the 2nd posture position and housed into the device main body after being folded. With this change, the paper feed opening 18 and either one 19 of the 1st and 2nd paper discharge opening are automatically blockaded at the paper feed stand 22 whose posture position has been changed to the 2nd one. That is to say, the paper feed stand 22 functions as a blockading door, and the intrusion of an outside foreign object to the inside of the device main body from the paper feed opening 18 and the paper discharge opening 19, is surely prevented. At this occasion, a sheet material course changeover means 16, in linkage with the change of this paper feed stand 22, is changed over so that it may guide the sheet material in the paper discharge opening direction of the other side which is not closed with the paper feed stand.</p> |
