摘要： A jetting element has a plurality of nozzles, a heating body for jetting ink droplets from the nozzles, and an ink chamber communicating with the nozzles. A manifold is bonded with the jetting element through an adhesive, and has an ink flow path formed therein to supply an ink to the jetting element. After the ink has been charged, the interior of the ink flow path is held at a negative pressure. An adhesive whose gas permeability is smaller than 2.0.times.10.sup.-6 cm.sup.3 .multidot.cm/cm.sup.2 .multidot.sec.multidot.atm and whose angle of contact with respect to the ink is 45.degree. or less is used as the adhesive. The bonded portion created by the adhesive has a smooth shape so that air bubbles are hard to adhere to the bonded portion.

摘要： An ink jet printer is disclosed which, only when ink is to be supplied, supplies ink from a main tank disposed outside a carriage and which can effect the supply of ink stably without the leakage of ink. When it is detected by an ink level sensor that the ink level in a second ink chamber of an ink tank has become lower than a predetermined position, pipes in ports are inserted respectively into slit valves provided in the second ink chamber. Then, by operating a pump, the air present in the second ink chamber is discharged by suction to increase a negative pressure in the second ink chamber, allowing ink to be supplied from a main tank into the second ink chamber. Thus, since the supply of ink is performed by a negative pressure, it is possible to prevent the leakage of ink from the portion where the pipe is inserted into the slit valve.

摘要： A drying device capable of keeping substantially constant the temperature of a moving recording sheet and evenly drying it without increasing radiation heat. Though the surface temperature of a recording sheet is lower on the upstream in the drying region and the temperature of outside air blown into the drying region is lower, the temperature of the recording sheet moved in the drying region is kept substantially constant by making the output of the upstream halogen lamp larger than that of the downstream halogen lamp. Even if the airflow velocity in the drying region is different, the radiation heat amount is adjusted according to the velocity to keep substantially constant the temperature of the recording sheet moved in the drying region. Thus, the recording sheet can be evenly dried and even if a jam of the recording sheet occurs in the drying region, there is no possibility of scorching, fuming or the like. The opening of a reflector holder is closed by a plate formed of heat resisting glass, and the plate is disposed parallel to a surface of a platen. By the plate, the airflow is kept from entering the reflector to generate a turbulent flow, but the airflow having passed round the reflector holder to be guided to the platen surface passes through a space formed by the plate and the platen to be rectified. Accordingly, the wind velocity in the space becomes constant, thereby the recording sheet can be evenly dried.
摘要翻译：一种干燥装置，其能够使移动的记录纸的温度基本上保持恒定，并且在不增加辐射热的情况下均匀地干燥。虽然记录片材的表面温度在干燥区域的上游较低，并且吹入干燥区域的外部空气的温度较低，但是通过使输出的干燥区域中移动的记录片材的温度保持基本上恒定的上游卤素灯大于下游卤素灯。即使干燥区域中的气流速度不同，根据速度调节辐射热量，使得在干燥区域中移动的记录纸的温度保持基本恒定。因此，记录纸可以均匀地干燥，并且即使在干燥区域中发生记录纸的堵塞，也不可能发生焦烧，发烟等。反射器支架的开口被由耐热玻璃形成的板封闭，并且板平行于压板的表面设置。通过板，气流不会进入反射器以产生湍流，但是已经通过反射器支架的气流被引导到压板表面，通过由板和压板形成的空间以进行整流。因此，空间中的风速变得恒定，从而可以使记录片材均匀地干燥。
