摘要： A printer with paper stacker activation. A platen is mounted on the drive roller for both rotation and translation. When fully to the right end of its travel, the platen is engaged with rotation stops which position the platen a fixed distance from the print cartridge, and disengaged from the roller, which can rotate for paper advancement during printing. When translated to the left, the platen is disengaged from the rotation stops and allowed to rotate. A clockwise rotation of the drive roller brings a roller shoulder into contact with a platen tab, urging the platen downwardly, clearing the way for the paper to fall into the output tray. Platen translation from right to left is driven by the carriage. A flag and a key are mounted on the roller, and engage the platen by the pen carriage. The key has a friction pinch on the roller, such that a torque is produced when the roller turns. The flag is adjacent the key, and the torque produced by the key urges rotation of the flag. The flag and key are constrained in rotation; when the roller rotates forward, the flag is lowered and will not engage the carriage. When the roller reverses, the flag is constrained to stop in a position which interferes with the carriage. Platen engagement occurs by driving the roller in reverse, rotating the flag into the pen carriage path, which then moves left, moving the platen.

摘要翻译： 具有纸堆叠器激活的打印机。 一个压板安装在驱动辊上，用于旋转和平移。 当完全到达其行进的右端时，压板与旋转止动器接合，其将压板与打印碳粉盒定位一定距离，并且与辊脱离，辊可以在打印期间旋转以进行纸张提前。 当向左转动时，压板与旋转止动器脱离并允许旋转。 驱动辊的顺时针旋转使辊肩与压板接头接触，向下推动压板，清除纸张落入输出托盘的方式。 从右到左的稿台翻译由车厢驱动。 标记和键被安装在辊上，并通过笔架与压盘接合。 该键在辊上具有摩擦夹紧，使得当辊转动时产生扭矩。 标志与钥匙相邻，由钥匙产生的扭矩促使旗帜旋转。 标志和键被限制旋转; 当滚轮向前转动时，标志下降，不能与滑架接合。 当辊反转时，标志被限制停止在干扰车厢的位置。 通过反向驱动辊子来进行压板接合，将标记转动到笔架路径中，然后向左移动，移动压板。
