    Abstract: A link member is rotatably supported by a lifting plate. When the lifting plate moves upward and downward, the movement of the link member is guided by a guide portion provided on a link guide hole. Before sheet feeding starts, the movement of the link member is regulated by a holding portion provided on a lower end of the guide portion so as to hold the lifting plate in a standby position against a biasing force of a feed spring. When the sheet is fed, a feed cam rotating integrally with a feed roller presses the link member to release the link member from being locked by the holding portion of the link guide hole to thereby make the link member movable along the guide portion.

    Abstract translation: 连杆构件由提升板可旋转地支撑。 当升降板向上和向下移动时，连杆构件的移动由设置在连杆导向孔上的引导部分引导。 在片材进给开始之前，连杆构件的移动由设置在引导部的下端的保持部限制，以便克服馈送弹簧的偏压力将提升板保持在待机位置。 当进给片材时，与进给辊一体旋转的进给凸轮压紧连杆构件以将连杆构件从连杆导向孔的保持部分锁定，从而使连杆构件沿导向部分移动。

    Abstract: A paper discharging apparatus for a printer includes: a plurality of support plates for supporting the paper and rotating in a direction parallel to a paper proceeding direction; a rotation shaft of a feed roller arranged in a direction perpendicular to the paper proceeding direction, and to which a feed roller contacting the paper is coupled; a power transfer portion having a sector gear installed on the rotation shaft so that the sector gear doe not rotate when the rotation shaft rotates in a forward direction, and the sector gear does rotate when the rotation shaft rotates in a reverse direction; a crank rod having one end connected to the sector gear, and reciprocating when the sector gear rotates; and a cam shaft connected to the crank rod and rotating in correspondence to the reciprocation of the crank rod. A cam for performing interference movement relative to the support plates, and a holder engaged with the rotation of the cam shaft and having a plurality of kickers for pushing the paper toward the support plate, are also provided. When the sector gear rotates in a forward direction, the paper is supplied or printed; when the sector gear rotates in a reverse direction, the holder is engaged with the cam shaft to perform angular movement by means of the crank rod connected to the sector gear so that an end portion of the paper is pushed. The paper is supported by the support plates, and is dropped downward and stacked. Thus, by using a power transfer portion having a simple structure, cost can be reduced and printing speed can be improved. Also, by using a crank rod and a cam shaft, discharged paper can be stably stacked without being damaged so that the paper can be stably discharged from the printer.

    Abstract translation: 一种用于打印机的排纸装置，包括：用于支撑纸张并沿平行于纸张行进方向旋转的多个支撑板; 馈送辊的旋转轴，其沿垂直于所述纸张行进方向的方向布置，并且与所述纸接触的进给辊被联接到所述转轴上; 动力传递部，其具有安装在旋转轴上的扇形齿轮，使得当旋转轴沿向前方向旋转时扇形齿轮不旋转，并且当旋转轴沿相反方向旋转时扇形齿轮确实旋转; 曲柄杆，其一端连接到扇形齿轮，并且当扇形齿轮旋转时往复运动; 以及连接到曲柄杆并且相应于曲柄杆的往复运动而旋转的凸轮轴。 还设置有用于相对于支撑板进行干涉移动的凸轮，以及与凸轮轴的旋转接合并具有多个用于朝向支撑板推动纸张的推杆的保持器。 当扇形齿轮向前旋转时，纸张被供应或打印; 当扇形齿轮沿相反方向旋转时，保持器与凸轮轴接合，以通过连接到扇形齿轮的曲柄杆进行角度运动，使得纸张的端部被推动。 纸张由支撑板支撑，并向下并堆放。 因此，通过使用具有简单结构的电力传递部分，可以降低成本并且可以提高打印速度。 此外，通过使用曲柄杆和凸轮轴，排出的纸可以被稳定地堆叠而不被损坏，使得纸张可以稳定地从打印机排出。

    Abstract: A sheet detecting apparatus that detects a sheet has a lever member; a biasing portion that biases the lever member for a first position where the abutting surface abuts against the leading end of the sheet; a supporting mechanism that movably supports the lever member to move in an order of the first position, a second position, and a third position, while keeping a abutting surface of lever member facing upstream; an interlocking portion that interlocks with the lever member; and a detector that detects a position of the interlocking portion. The second position is a position to which the lever member moves by the sheet being conveyed against the biasing force of the biasing member, and the third position is a position where the abutting surface is positioned upstream in the sheet conveying direction of a position of the abutting surface at the second position and where the lever member abuts the surface of the sheet being conveyed and stands by to move to the first position when a trailing end of the sheet passes the lever member.
