    • An image forming apparatus which includes a paper delivery unit which is provided as to be rockable and displaceable between an operating position close to a photosensitive drum and a standby position remote from the photosensitive drum; a supporting link system, operably coupled to the paper delivery unit, for holding the paper delivery unit at the operating position; and energizing device, operably coupled to the supporting link system, for energizing the paper delivery unit so as to move from the standby position to the operating position. The paper delivery unit includes a transferring device for transferring a toner image from the photosensitive drum onto a sheet, a tractor for feeding the sheet, disposed in the upstream of the transferring device in a paper delivery direction, and a suction feeder for holding and delivering the sheet, disposed in the downstream of the transferring device in the paper delivery direction. A delivery unit frame for supporting the transferring device, the tractor and the suction feeder is pivotally supported by a body frame disposed in the upstream in the paper delivery direction. In other words, the paper delivery unit is held at its operating position by way of the supporting link system, and is moved back to the position from its retracted position by way of the energizing device. The paper delivery unit is thus capable of moving to and from an operating position for, e.g., ease of cleaning the transferring device or removing jammed papers.
    • 一种图像形成装置,其包括纸张传送单元,该纸张传送单元被设置为在靠近感光鼓的操作位置和远离感光鼓的待机位置之间可摆动和移位; 支撑连杆系统,可操作地联接到纸张传送单元,用于将纸张传送单元保持在操作位置; 以及激励装置,其可操作地联接到所述支撑连杆系统,用于对所述纸张传送单元进行激励,以便从所述待机位置移动到所述操作位置。 纸张传送单元包括用于将调色剂图像从感光鼓转印到纸张上的转印装置,设置在纸张输送方向上的转印装置的上游的纸张供给用拖拉机,以及用于保持和输送的抽吸供给装置 该片材沿纸张输送方向布置在转印装置的下游。 用于支撑传送装置的传送单元框架,拖拉机和抽吸进给器由设置在纸张传送方向上游的主体框架枢转地支撑。 换句话说,纸张传送单元通过支撑连杆系统保持在其操作位置,并且通过激励装置从其缩回位置移回到该位置。 因此,纸张传送单元能够移动到操作位置和从操作位置移动,以便例如易于清洁传送装置或移除卡住的纸张。
