摘要： PROBLEM TO BE SOLVED: To provide a recorder for always recording high quality images by suppressing deterioration in an image due to non-ejection of a nozzle suddenly occurring during the recording. SOLUTION: This recorder performs the recording by using a full line head such that a recording medium is attracted to a conveyance belt to be conveyed. The recorder comprises a means for recording a chart on the surface of the conveyance belt and a reading means for reading the chart. The recorder prevents ink mist or the like from being adhered to a detection face of the reading means by controlling an airflow at a portion in the vicinity of the detection face.

摘要： PROBLEM TO BE SOLVED: To provide an inkjet recorder which can reduce a decrease of a printing speed even when images of a high printing duty continue by controlling a paper-feeding interval timing according to a printing duty of one page of a recording image, and which can prevent a decrease of a recording quality by carrying out recording also with a head temperature in a regulated temperature range at all times. SOLUTION: In the controlling system of transfer of recording papers, the inkjet recorder comprises a recording head which consists of one or a plurality of full line-type inkjet recording heads with a recording element array corresponding to a width of a recording medium, a recording medium feeding means which supplies the recording medium, a transfer means which transfers the recording medium by a rotating belt at all times when recording is carried out, and a recording pixel number counting means which counts the number of ejections recorded in one page of the recording image. When the printing duty is high according to information from the recording pixel number counting means, such control as delaying a timing of recording medium-feeding from the recording medium feeding means is carried out by a value of the printing duty. Thus stopping of recording due to cooling is eliminated, so that printing is carried out continuously. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce positional shift of recording element in the direction orthogonal to raster. SOLUTION: A recording head having a plurality of recording elements arranged in correspondence with the maximum recording width of a recording medium and performing recording by ejecting an ink drop from each recording element is fixed at a specified angle traversing a plurality of raster regions (M-1, M, M+1), when the recording region of the recording medium is divided into a number of raster regions corresponding to the maximum recordable rasters. Recording data being transmitted to each recording element is selected such that recording data corresponding to one raster (M) of image data being recorded is recorded in the same raster region (M) on the recording medium and then each recording element is driven by time sharing thus performing recording.

摘要： PURPOSE: To enable recording of image information in a state wherein no fraction occurs in the number of longitudinal dot lines before and after conversion of the resolution of the image information, by converting the resolution of image data at a prescribed ratio so that the fraction may not occur in the number of the longitudinal dot lines after the conversion. CONSTITUTION: First, reading of a first longitudinal dot line 301 is executed. In case when the ratio of conversion of a resolution is 4/5, a five-dot line of an original image turns into a converted image of a four-dot line after conversion of the resolution. Accordingly, longitudinal 45 dots (from the first set to the ninth, i.e., 5×9 dots) of the first longitudinal dot line 301 are converted into 36 dots (4×9 dots). As the result, three dots in the tenth set (i.e., dots from the forty-sixth to the forty-eighth of the first longitudinal dot line 301) are left unconverted. Then, reading of a second longitudinal dot line 302 is conducted.

摘要： PURPOSE: To accurately inform a user of an error in picking up caused by the sticking of paper powder, to provide a sequence of function recovering operations and to start it from an operating part or a host. CONSTITUTION: Printing papers 301 are loaded in a paper stacker 303 capable of moving on a supporting point 302 as a fulcrum and the presence of the printing papers is confirmed by an ASF paper sensor 304. The printing paper 301 held by a paper pressing spring 305 and a pickup roller 312 passes through a separating pawl 306, to be supplied to a printing part in the rotational direction of the pickup roller 312. The passage of the paper is detected by a paper path sensor 311. Further, the paper is held by a driving roller 308 and a carrying roller 310, to be carried to the position of a printing head 309. After that, printing information is printed by the printing head 309 and the paper is ejected outside a printer by ejecting rollers 307.

摘要： PURPOSE: To shorten the processing time of image data by inhibiting the transfer of those parts where the images are not formed between an image data supply source and an image forming device. CONSTITUTION: The coordinates of the blanks where the graphic forms such as ○, ▵, etc., are not drawn in Fig. (B) show the non-print parts. The print data are successively moved to the non-print parts, so that the print image information shown in Fig. (B) can have a memory constitution that is shown in Fig. (C). A printer has an actual memory only at an upper part 103 and has no substantial memory in a non-print part 104 shown in Fig. (C). Therefore, the print data which are sent to the printer from a host has such a constitution as shown in Fig. (D) and it is not required to send the part 104 to the printer from the host as the print data. Thus a print image can be formed only by the print mode of the printer and the data on the printable part 103.

摘要： PURPOSE: To embody the function detecting a desired ink residual amt. with a high accuracy in an ink tank having a negative pressure producing member such as an absorbing member or a foam material built therein. CONSTITUTION: The detection light of a photointerruptor 6 is transmitted through a part of the wall surface of an ink tank composed of a transparent plastic pervious to the detection light of the photointerruptor 6 and the change of the light reflectivity of the boundary part of the wall surface and an ink absorbing member 7a is detected. At that time, a detection process detecting the reflection quantity of light in a specific timing by a detection means to output the obtained data and a comparison process comparing the output result of the n-th time (n>=2, integer) with the output detection result of the (n-1)-th time or up to the (n-1)-th time are provided and, when there is a change of a specific value α or more, it is informed that the residual amt. of the ink in the ink tank is little.

摘要： PURPOSE: To perform an image reduction which never eliminates thin lines in an original image even after the reduction by performing switching to a reduced part with a reduction pattern, deleting the reduced part from an input image, and then outputting the image after the deletion as a reduced image. CONSTITUTION: With the reduction pattern, the position of a dot to be deleted for longitudinal reduction is changed through the switching of switches SW1-SW3, and the reduced part is deleted from the input image. For the deletion of a laterally reduced part, a signal which is divided in frequency in a half through JK flip-flops 52701 to 52704 is inputted to a multiplexer 52709 through one of gates 52705 to 52708. The signal is inputted from the multiplexer 52709 to a gate 52710. To the other terminal of the gate 52710, DS'* is inputted to obtain a masked output signal and the reduction is performed. The image after the longitudinal and lateral deletion is outputted as the reduced image by a reduction device. Therefore, the image reduction is performed without disappearance.

摘要： PURPOSE: To suppress the generation of texture when an image is reduced by thinning out. CONSTITUTION: Image data which are divided into blocks are inputted to a pattern matching device 42104. This pattern matching device 42104 calculates to the inputted image blocks on the basis of featured image blocks of an image such as a line drawing, a contour, a dither image, and an error diffusion image and outputs which feature is expressed most, as a label in a feature table. On the basis of the discriminated information, a thinning-out device 42107 thins out the image by the best thinning-out method among plural thinning-out methods.
