    • A paper feeding device for a printer, which is constituted by a paper feeding tray and a tray receiver. The paper feeding tray has a rotatable hopper plate supported at the bottom thereof, a hopper shaft disposed at the lower surface of the front end of the hopper plate, two moving levers respectively connected to two ends of the hopper shaft, and movably supported by two sides of the paper feeding tray, guide grooves formed in the two sides in the tray fitting direction, two movable members supported by the two guide grooves, and have outwardly extending securing portions, and a spring disposed between the movable levers and the movable members, and for pushing up the hopper plate through the hopper shaft with respect to the movable lever.A tray receiver contains two side plates disposed at a certain interval which allows the paper feeding tray to be inserted, securing grooves on the inner surfaces of the rear portion of the two side plates, and which engage with the securing portions during the mounting of the paper feeding tray, and which prevent the movement of the movable members and expands the spring to increase spring force, and a lock cam movably supported on the inner surface of the front portion of the two side plates, and which has a cam surface to which the hopper shaft can be engaged when the paper feeding tray is mounted.
    • 一种用于打印机的送纸装置,其由进纸托盘和托盘接收器构成。 供纸托盘在其底部具有可旋转的料斗板,设置在料斗板前端下表面的料斗轴,两个分别连接到料斗轴的两端的移动杆,可移动地由两个 供纸托盘的侧面,在托盘配合方向上形成的两侧的引导槽,由两个引导槽支撑的两个可动构件,并且具有向外延伸的固定部分,以及设置在可动杆和可动构件之间的弹簧, 并且用于相对于可动杆将料斗板推过料斗轴。 托盘接收器包含以一定间隔设置的两个侧板,其允许进纸盘被插入,将两个侧板的后部的内表面上的固定槽固定在两个侧板的后部的内表面上,并且在安装 进纸盘,并且防止可动件的移动并使弹簧膨胀以增加弹簧力;以及锁定凸轮,其可移动地支撑在两个侧板的前部的内表面上,并且具有凸轮表面 当安装进纸托盘时,料斗轴可以接合。
