摘要： According to the present invention, there is provided an ink jet recording apparatus for recording an image on a recording medium by discharging ink to the surface of the recording medium, wherein ink is reserved in an ink tank including a negative pressure generating member, such as an absorber and a foaming member, and a function of accurately detecting the residual quantity such that depletion to a predetermined level can be detected is realized. Light emitted by a photointerrupter is allowed to pass through a portion of a wall surface of the ink tank made of transparent plastic or the like which is transmissible with respect to detection light emitted by the photointerrupter to detect change in the light reflectance in the boundary portion between the wall surface and the ink absorber. In accordance with reflectance obtained in a case where no ink exists in the detected portion and that obtained in a case where ink exists, the residual quantity of ink can be detected.

摘要： A sheet feeding apparatus includes a discharge rotary body, a pinch rotary body, a drive transmission rotary body and a regulation member. The discharge rotary body feeds and discharges a sheet from a recording section. The pinch rotary body is disposed facing the discharge rotary body for pinching and feeding the sheet along the discharge rotary body. The drive transmission rotary body has a circumferential surface contacting a circumferential surface of the discharge rotary body with a pressure exerted in a direction different from a straight line drawn between rotary centers of the discharge rotary body and the pinch rotary body, for rotationally driving the discharge rotary body. The regulation member contacts the discharge rotary body when deformation of the discharge rotary body exceeds a predetermined quantity arising due to pressure from the drive transmission rotary body and regulates deformation of the discharge rotary body from exceeding the predetermined quantity.

摘要： Ink jet recording encounters deviations in the position at which a recorded dot is applied due to changes in the distance from the recording head to a recording medium, the carriage movement speed and the ink discharge speed or the like. When bidirectional recording is performed while moving the carriage having the recording head mounted thereon, deviations of the recorded dot may occur in the forward and rearward recording operations. The present invention is arranged in such a manner that values for correcting the deviations occurring in bidirectional recording and corresponding to the changes of the distance from the recording head to a recording medium, the carriage movement speed and the ink discharge speed or the like are previously stored. A drive signal, the timing of which has been corrected with the correction value, is used to operate the apparatus so that high-quality recordings free from deviations occurring in the bidirectional recording operation are obtained. The present invention disclosed a recording apparatus having a plurality of recording heads mounted on a carriage thereof, the recording apparatus being arranged in such a manner that the carriage movement speed is detected to determine the recording timing of the plural recording heads to prevent the deviation of dots formed by the plural recording heads due to the changes in the moving speed caused by changes in the environment of the apparatus to record high quality images.

摘要： A recording head includes an ink-discharging surface and nozzles. The ink-discharging surface is provided with ink-discharging ports of the nozzles. A light-emitting element and a light-receiving element are disposed opposite each other close to the ink-discharging surface. The light-receiving element outputs a detection signal. A reflector is provided on the ink-discharging surface and reflects light emitted from the light-emitting element toward the light-receiving element. One of the nozzles is driven and whether the nozzle discharges an ink drop is checked on the basis of change in the detection signal due to interception of the reflected light by the ink drop. If the nozzle discharges an ink drop, then whether the nozzle discharges the ink drop in an appropriate direction is checked on the basis of change in the detection signal due to interception of the direct light by the ink drop.

摘要： A detection unit to optically detect a discharge condition of a droplet is disclosed. The detection unit includes a light emitting element and a light receiving element disposed on opposite sides of an area through which a droplet discharged from a droplet-discharger passes. A diaphragm plate having an aperture and another diaphragm plate having at least two apertures arranged at a pitch in a discharge direction are respectively disposed near front surfaces of the two elements. When light emitted from the light emitting element passes through the apertures, two light beams are received by the light receiving element. When the droplet is discharged and passes in front of the apertures, the two light beams are blocked sequentially by the ink droplet, which causes the quantity of light received by the light receiving element to change, thereby inducing a change in an output from the light receiving element. Based on the change in the output, a discharge-condition of the droplet is determined.
