摘要： In a one-face mode, a first sheet discharge portion arranged on an upper face of an apparatus body, or a second sheet discharge portion arranged in the apparatus body so as to be freely opened and closed is opened, and a sheet forming an image on one surface thereof is discharged to this second sheet discharge portion. In a both-face mode, a sheet forming images on both surfaces thereof is conveyed to the first sheet discharge portion through a sheet discharge path formed by closing the second sheet discharge portion. When it is detected in the both-face mode that the second sheet discharge portion is opened on the basis of a detecting signal from a second sheet discharge portion open and close detecting portion, a controller controls the rotating direction of a forward and reverse rotatable conveying device on the basis of timer information from a timer device at the detecting time and the sheet forming the image on one surface thereof is conveyed to the first sheet discharge portion or the second sheet discharge portion, or a both-face conveying portion.

摘要： A position detecting sensor for detecting that a sheet having come into an openable both-face conveying path for reversing the surfaces of the sheet having an image formed on one surface thereof and conveying the reversed sheet to an image forming portion has arrived at a predetermined re-feeding position, and the position detecting sensor is designed to be capable of detecting also the presence or absence of the occurrence of jam in the both-face conveying path, the mounting and dismounting of a both-face conveying portion and the opening and closing of the both-face conveying path.
摘要翻译：一种位置检测传感器，用于检测进入可打开的双面输送路径的纸张，以便使具有形成在其一个表面上的图像的纸张的表面反转并将反转的纸张传送到图像形成部分已经到达预定的重新进给位置，并且位置检测传感器被设计成能够还检测双面传送路径中是否存在卡纸的发生，两面传送部的安装和拆卸以及打开和关闭的两面输送路径。
