    Abstract: An image forming apparatus includes an auto document feeder, a scanner, a paper tray, and an image forming mechanism. The auto document feeder feeds an original sheet having an image and includes an original tray configured to load the original sheet having the image and a detecting mechanism configured to detect the original sheet set on the original tray. The detecting mechanism includes a terminal including a plane surface disposed to form a predetermined angle with respect to a sheet conveyance direction. The scanner scans the image on the original sheet fed by the auto document feeder to create image data. The paper tray supplies a recording medium. The image forming mechanism forms an image on the recording medium supplied from the paper tray with a developer according to the image data created by the scanner.

    Abstract: A paper path switching mechanism including a plurality of feeding rollers which feed a page when the page is pressed against the feeding rollers by guide members of a switching guide. The switching guide has long guide members which press the paper against the feeding rollers and short guide members positioned near the edges of the page. The short guide members guide the page without imparting too much resistance at the edges of the page in order to reduce the frequency of paper jams. The longer guide members are tapered in width at portions near the periphery of the feeding rollers in order to reduce the size of the contact area of the page to the long guide members which reduces resistance on the page and consequently reduces paper jams. After the page passes between the switching guide and feeding rollers, its direction of travel is reversed and the page again contacts the switching guide but moves along a different edge of the guide members and along a different paper path in order to invert pages.

    Abstract: In an image forming apparatus, a device for turning a paper of the present invention has a transport roller constantly rotatable in a predetermined direction for paper transport. A reverse transport member is positioned downstream of the transport roller in the predetermined direction, and transports the paper, transported by the transport roller, in the direction opposite to the predetermined direction. A turn guide has a first guide face for guiding the paper toward the transport roller, and a second guide face for guiding in a paper discharge direction the paper being transported by the reverse transport member in the direction opposite to the predetermined direction. The end portion of the first and second guide faces close to the reverse transport member extends in the direction in which the end portion intersects the periphery of the transport roller. Hence, the end portion is angularly retracted by the paper, being guided by the first guide face, to a position coincident with a line tangential to the transport roller. The end of the turn guide is configured such that the first and second guide portions are tapered. The device is miniature and reduces resistance to act on the incoming paper and surely urges it against the transport roller to generate a driving force. As a result, the paper is prevented from being skewed or caught or from jamming the path.

    Abstract translation: 在图像形成装置中，本发明的纸张的转动装置具有能够沿预定方向恒定旋转的输送辊，用于纸张输送。 反向传送部件沿着预定方向位于传送辊的下游，并且传送由传送辊传送的纸张沿与预定方向相反的方向。 转向引导件具有用于将纸张朝向输送辊引导的第一引导面，以及用于沿纸张排出方向沿与预定方向相反的方向由反向传送构件传送的纸张引导的第二引导面。 靠近反向输送构件的第一和第二引导面的端部沿着端部与输送辊的周边相交的方向延伸。 因此，端部由纸被角度地缩回，由第一引导面引导到与传送辊相切的线重合的位置。 转向导向件的端部被构造成使得第一和第二引导部分是锥形的。 该装置是微型的并且减小了作用在入纸上的阻力，并且肯定地将其推送到输送辊上以产生驱动力。 结果，防止纸被歪斜或卡住或妨碍纸张的路径。
