摘要： An ink supply passage 16 has a large cross-sectional area and ink tanks 6 are connected to the top of the ink supply passage 16. An ink supply passage 17 is a flow passage shaped like a semicylinder and has a cross-sectional area equal to or smaller than the cross-sectional area of the ink supply passage 16. Even if bubbles are mixed into the ink supply passage 17, they adhere to the upper portion of the flow passage 17 and do not flow into lower corners, so that a flow passage can be provided and the ink flow is not hindered. Since an ink supply passage 19 connected to a head chip 4 has a small diameter, bubbles mixed into the ink supply passage 19 can be removed by maintenance for sucking ink forcibly. Bubbles mixed upstream are not transported to the ink supply passage 19 because of the flow rate difference caused by the cross-sectional area difference.

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： An exposure device includes an exposure section and first and second signal output units. The exposure section has plural light emitting elements. The first signal output unit outputs to the exposure section a first signal for determining timings for starting and ending light emission of the respective light emitting elements. The second signal output unit outputs to the exposure section a second signal for determining as to whether the respective light emitting elements are caused to emit light for respective pixels. If light mission of the respective light emitting elements is stopped with respect to all pixels of one line in a main scanning direction, the first signal does not output to the exposure section for each group of one or plural light emitting elements that operate based on the common first signal.
