    摘要： For eliminating waste of ink and achieving high charging efficiency with a reduced charging time where a printing head is equipped with a second tank for reserving a predetermined amount of ink and a supply system is configured to supply ink from a first tank to the second tank intermittently, the second tank is provided with a variable internal volume. The internal volume is varied to cause the second tank itself to function as an actuator for charging ink and performing a venting process. Specifically, the internal volume is forcibly reduced to cause a reverse flow of a gas residing in the second tank along with ink into the first tank, which makes it possible to generate of waste ink that is released to the outside. A normal charging operation can be completed simply by causing a change in the opposite direction (the direction of increasing the internal volume). Relatedly, the second tank may be provided with a member for holding ink and generating a negative pressure originating from an elastic force. With connection of the first tank and the member, the pressure in the second tank is reduced to cause the member to expand, thereby introducing ink into the same. This introduction is stopped by regulating the expansion with a displaceable unit which expands when the pressure is reduced. The regulation is performed at such a position that the negative pressure generated in the member by canceling regulation is in equilibrium with an ink meniscus-holding ability of the printing head.

    摘要翻译： 为了消除墨水的浪费并且在减少充电时间的情况下实现高的充电效率，其中打印头配备有用于保留预定量的墨水的第二罐，并且供应系统被配置为间歇地将墨水从第一罐供应到第二罐 ，第二罐具有可变的内部容积。 内部容积变化，使得第二罐本身用作用于对油墨进行充气并执行排气过程的致动器。 具体地说，内部体积被强制地减少，导致第二罐中存在的气体与油墨一起反向流入第一罐，这使得可以产生释放到外部的废墨。 可以简单地通过使相反方向（内部容积增加的方向）发生变化来完成正常的充电操作。 相关地，第二罐可以设置有用于保持油墨并产生源自弹性力的负压的构件。 通过第一罐和构件的连接，第二罐中的压力减小，使构件膨胀，从而将油墨引入其中。 通过用可移位单元调节膨胀来停止该介绍，当压力降低时，该位移膨胀。 在通过取消调节而在构件中产生的负压与打印头的墨水弯月面保持能力平衡的位置进行调节。

    摘要： An original document feed tray is positioned above an original document output tray. When original documents are set on the original document feed tray, the original document feed tray is moved upwardly from a home position to a position where the uppermost original document sheet can be transported to an original document transport mechanism. When the original document feed tray is lifted in accordance with the reduction of the original documents on the original document feed tray after the original documents are transported to the original document transport mechanism, the original document feed tray is lifted to a position, above the position where all original documents on the original document feed tray were transported to the original document transport mechanism.

    摘要： A printing apparatus is provided which has an eject guide capable of guiding print mediums of different thicknesses, that have been transported there, to a nip portion of the eject rollers of the fixed diameters. To this end, the eject guide is pivotally supported at one end thereof on the platen. The eject guide is positioned with the other end engaged with the chassis. In this state, as the platen moves the eject guide pivots.

    摘要： An ink jet recording apparatus includes a cap capable of moving in approaching and receding directions against and away from a discharge port surface of a recording unit for covering the discharge port surface, a wiper sliding while contacting with the discharge port surface to wipe the discharge port surface to clean it, a wiper driving gear for transferring drive to the wiper, a cam and gear member equipped with a cam portion for controlling the movement of the cap and a gear portion for transferring drive to the wiper driving gear, in which the cam and gear member is configured so that the gear portion engages with the wiper driving gear after the cap has moved to a position where the cap does not interfere with the wiper. By such a configuration, both of the capping operation and wiping operation can be controlled with the single cam and gear member, which makes it possible to miniaturize a recovery mechanism portion for maintaining and recovering the ink discharging performance of the recording unit. Thereby, the recording apparatus body can be miniaturized.
