摘要： 1. A sheet feeding apparatus for a printer comprising:
a cylindrical platen (11, 107) rotatably attached opposite to a printhead (13, 105);
a paper feeding means (16, 17, 111; 18, 19, 125) for feeding a sheet of paper through between said printhead (13, 105) and said platen (11, 107); and
a transmission frictionally connected with said platen (11, 107) for transmitting the torque on said paper feeding means (16, 17, 111; 18, 19, 125) to said platen (11, 107) so as to rotate said platen (11, 107) through friction drive.摘要翻译： 打印机中的送纸装置设有：用于在其间保持和供纸的进给辊（112,126）; 以及操作杆，用于根据纸张的类型（例如，由拖拉机转移的连续形式）或者通过拖拉机转移的连续形式，通过将进给辊连接或从相对的进给辊（114）拆卸进给辊来改变进给辊（112）的接触压力 一个手动插入的切片。 操作杆还与设置在驱动马达（121）和销拖拉机（148）之间的离合器机构与进给辊的连接/拆卸操作同时连接或断开。 操作杆的单一操作可以在将另一种类型的纸张悬挂在打印机中的同时实现所选类型的纸张的精确转印。 片材进给装置还设置有用于通过摩擦驱动力在压板（107）和进给辊之间传递扭矩的传动机构（132,138）。 传动机构防止压板的惯性力无用地使进给辊旋转。

摘要： A sheet feeding apparatus in a printer is provided with: feeding rollers (112,126) for holding and feeding a sheet of paper therebetween; and an operation lever for changing the contact pressure of the feeding rollers (112) by attaching or detaching the feeding roller to or from the opposite feeding roller (114) depending on a type of sheet, e.g., a continuous form transferred by pin tractors or a manually inserted cut sheet. The operation lever also connects or disconnects a clutch mechanism provided between a drive motor (121) and the pin tractors (148) simultaneously with the attaching/detaching operation for the feeding rollers. A single operation of the operation lever can achieve a precise transfer of a selected type of sheet while suspending another type of sheet in the printer. The sheet feeding apparatus is also provided with a transmission mechanism (132,138) for transmitting a torque between the platen (107) and the feeding rollers by a friction driving force. The transmission mechanism prevents the inertia force of the platen from rotating the feeding rollers uselessly.

摘要： A liquid ink printing machine (10), for forming an image on a recording medium (30) moving along a path, including a jam clearance drive gear disengagement mechanism. The printing machine includes a transport roller (40), to move the medium along the path, a drive gear assembly (58,60,62,64,66,68,70,72) which is coupled to the transport roller, to drive the transport roller and which is disengageable to free the transport roller for movement to provide for removal of the medium in the event of a jam. A stepper motor (52), coupled to the gear assembly, moves the gear assembly for which in turn moves the transport roller for advance of the recording medium along the path. An actuating arm (44) is displaced by the liquid ink printhead carriage (20), in the event of a jam, to disengage the drive gear assembly, thereby freeing the transport roller for unrestricted movement in at least one direction for removal of the recording medium in the event of a jam or inadvertent sheet stoppage. A printer controller (54) moves the gears of the gear assembly to reengage the gears once the jam has been cleared.
