摘要： Image forming apparatus including a paper return device for feeding a sheet of paper ejected from a paper output port opening in a main body of the apparatus to its outside back to a paper feeding port also opening in the main body to its outside. For double-sided copying operation, the sheet of paper ejected from the paper output port carrying an image on one side only is returned to the paper feeding port and fed again to an image former from the paper feeding port so that it is not necessary to provide a dedicated paper path for re-feeding the paper. The apparatus includes a paper sensor which senses the paper inserted into the paper feeding port and outputs a paper sensing signal, a discriminator for judging whether the paper return device is in an operating condition, and a paper feed controller which controls a driver for driving a paper feeder such that the paper feeder initiates a paper feed operation when the paper sensing signal is output while the paper return device is in its operating condition.
摘要翻译：图像形成装置包括一个纸张返回装置，用于将从装置的主体中的开口的纸张输出端口向其外部输送的纸张馈送到也在主体中打开到其外部的供纸口。对于双面复印操作，仅从一侧承载图像的纸张输出端口排出的纸张返回到供纸口，并且再次从供纸口向成像器供纸，因此不需要提供专门的纸张路径，以重新供纸。该装置包括：纸张传感器，其感测插入进纸口中的纸张并输出纸张感测信号;判别器，用于判断纸张返回装置是否处于工作状况;以及供纸控制器，其控制驱动器驱动供纸器，使得当纸张返回装置处于其操作状态时，当纸张感测信号输出时，供纸器启动供纸操作。

摘要： In an image forming apparatus which uses a hollow space between an image reading section provided in an upper part of the apparatus and an image forming section provided in a lower part of the apparatus as a paper output space, the hollow space is used also as a space for temporarily holding a sheet of paper during a switchback operation. This arrangement helps prevent physical contact between the paper and the body of an operator or other objects and makes it easier to deal with a paper jam which is likely to occur during the switchback operation.

摘要： A paper return device detachably fitted to an image forming apparatus having a paper feeding port for feeding paper from outside the image forming apparatus, a paper transport mechanism for transporting the paper from the paper feeding port to an image forming unit and a paper output port from which the paper carrying an image formed by the image forming unit is ejected to the outside of the image forming apparatus. The paper return device includes a paper return guideway which connects the paper output port of the image forming apparatus to its paper feeding port when the paper return device is fitted to the image forming apparatus, whereby the paper ejected from the paper output port is fed back to the paper feeding port through the paper return guideway.

摘要： An image forming apparatus has a paper discharging section provided in its main body. The paper discharging section opens toward the front of the main body. An opening serving as a window for introducing light into the paper discharging section is provided on a side surface of the main body. Light enters the paper discharging section through the opening, so that the paper discharging section is brightened. As a result, it is possible to easily visually confirm whether or not a paper sheet exists in the paper discharging section. Additionally, vent holes adjacent the window opening serve to introduce cooling air along the axis of a fusing roller.
