An image recording apparatus records an image on a recording medium by causing a recording head having an arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements. The apparatus comprises a setting device to set the number of main scannings by the recording head; a main scanning device to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting device; and a sub-scanning device to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defects at all times.

Image recording apparatus and method for recording an image on a recording medium

An inkjet recording apparatus has a structure in which, when a recording-interruption operation of a recording head such as discharge-recovery processing is performed during an image-forming operation, a recording downtime is measured, and the recording head is heated in accordance with the length of a recording downtime so as to prevent occurrence of differences in optical densities and colors of an image before and after the recording-interruption operation.

Image recording apparatus for recording an image on a recording medium

A printing apparatus in which a printhead and a print medium intermittently move relatively to each other, and the printhead performs printing on the print medium during the relative movement. The temperature of the printhead is detected, the detected temperature is compared with a predetermined threshold value, and start of new relative movement accompanied by printing is controlled in correspondence with the result of comparison. The threshold value is set in correspondence with information regarding the number of pixels for which the printhead can perform printing during one relative movement. By this arrangement, reduction of output speed can be suppressed as much as possible, and inconveniences due to temperature rise of the printhead can be prevented.

To improve convenience of a wheelchair by enabling an outside fitting type of auxiliary power device to be automatically and securely mounted on and removed from the habituated wheelchair, the auxiliary power device, which can be mounted on and removed from the wheelchair and provide power assistance to the wheelchair, comprises photoelectric sensors for detecting positions of predetermined frames of the wheelchair, arms, each having a handle of a shape capable of being engaged with the frames attached to an outer end thereof, and driving motors for displacing the arms. When the frames are determined to be at predetermined positions based on information from the photoelectric sensors, the arms are displaced by the driving motors so as to have the handles engage with the frames.

Auxiliary power device of wheelchair

An image outputting apparatus is provided with a reproduction circuit for reproducing moving images from a recording medium by operating a recording-medium transport circuit, a recording circuit for recording on a recording substance an image for one picture included in the moving images by operating a feeding circuit which feeds the recording substance, and a control circuit arranged to control the feeding circuit to feed the recording substance to a predetermined position so as to shift a recording position on the recording substance, while controlling the recording-medium transport circuit to transport the recording medium to a predetermined position, and to control. the recording medium-transport circuit and the recording circuit in an interlocked manner so as to record the image for one picture on the recording substance. The arrangement of these parts in combination permits reduction in capacity of an image memory and also in processing time of the apparatus.

Image outputting apparatus

An ink jet textile printing method forms an image on cloths in an image forming operation by repeating a step of applying ink on the cloths from an ink discharge port of a recording head, the recording head relatively main-scanning to form the image in a main scan direction, and a step of relatively conveying the cloths in a sub-scan direction. The method includes the steps of forming the image on the cloths by applying ink on the cloths from the recording head based on image data. The method further includes the step of temporarily stopping the image forming operation in accordance with an indication to effect a temporary halt of the image forming operation. When the temporary halt is indicated while the recording head performs a main scan in the image forming operation, the image forming operation by the main scan is completed, and then the temporary halt of the image forming operation is effected by moving the recording head to a standby position. The method still further includes the step of releasing the temporary halt of the image forming operation and restarting the image forming operation in accordance with an indication for releasing the temporary halt of the image forming operation. When the release of the temporary halt is indicated, ink is discharged from the ink discharge port and then the image forming operation is restarted.

An image recording apparatus for recording an image in accordance with input image data supplied thereto using a recording head having a plurality of recording elements arranged thereon. The apparatus includes a sensor for detecting and determining non-uniformity of the densities of the records provided by the respective recording elements, at predetermined timing in image recording operations, and adjusting means for adjusting driving signals applied to the respective recording heads in response to an output of sensor.

Image recording apparatus having a variation correction function

An image recording apparatus for moving, relatively to a cloth recording medium, a recording head for discharging ink so as to record an image. The image recording apparatus is arranged such that the operation conditions of the recording head can be changed at the time of the recording operation in accordance with the thickness of the cloth, or the diameter of the fiber or the pitch of weaving the fiber of the cloth, so that the quantity of ink to be supplied to the cloth to record an image is controlled so that a high quality recorded image can be obtained regardless of the type of the cloth.

Image recording apparatus for a cloth recording medium

An ink jet textile printing apparatus for performing printing by reading an original image created by a designer, converting the original image into original data represented by an electric signal, retrieving the original data for processing to be output as image data, and recording data on cloth based on the image data. The ink jet textile printing apparatus has a first ink jet recording head provided upstream of a recording position, and a second ink jet recording head provided downstream thereof, and is provided with a drying unit located between the recording heads, whereby high-quality recorded images with less bleeding can be obtained by recording on a recording area again with the second ink jet recording head after drying the recording area on the cloth recorded by the first ink jet recording head with the drying unit.
