Abstract: An image printing apparatus, an image printing system, an image processing method and a memory medium are provided for preventing the image printing apparatus from being occupied for a long time by a single user, thereby enabling efficient utilization of the printing resources. Discrimination is made as to whether image formation is possible based on the image data transferred from a host apparatus, according to the printing condition based on such image data, and the image data are stored in a memory device in case the image formation is judged to be impossible. Preferably, even if image formation is possible, a discrimination is also made as to whether fully adequate image formation is possible. In addition, there may be formed a list of the images in order to enable judgment by a user of the images of all the received pages or, after the image forming operation, identification of the images of the pages for which the image formation is judged to be impossible.

Abstract: There is disclosed an X-ray analyzer capable of precisely measuring a trace amount of cadmium contained in plastic. The analyzer has an X-ray filter assembly between an X-ray tube having an Rh target and a plastic sample. The filter assembly consists of first, second, and third X-ray filters which are made of zirconium, copper, and molybdenum, respectively. The first through third X-ray filters have thicknesses of about 100 ?m, 200 ?m, and 40 ?m, respectively.

Abstract: A recording apparatus includes a conveying device for conveying a recording medium, a recording rotary unit in which a recording device for recording an image on the recording medium and a recording medium holding device for supporting the recording medium with respect to the recording device are opposed to each other, and a rotating device for rotating the recording rotary unit.

Abstract: An ink jet recording apparatus includes a conveying device for conveying a recording sheet, a first recording device for discharging ink to a first surface of the recording sheet conveyed by the conveying device to thereby record an image thereon, a second recording device for discharging ink to a second surface opposite to the first surface of the recording sheet conveyed by the conveying device, a first ink receiving device disposed at the first surface side of the recording sheet for receiving the ink discharged from the second recording device, and a second ink receiving device disposed at the second surface side of the recording sheet for receiving the ink discharged from the first recording device.

Abstract: A recording apparatus for effecting recording on a recording medium by a recording head having a first recording portion and a second recording portion includes a recording medium conveying path for conveying the recording medium in opposed relationship with the recording head, and a reversing mechanism portion disposed in the recording medium conveying path, the reversing mechanism portion spacing a first side of the recording medium apart from the first recording portion, and thereafter reversing the recording medium so as to oppose a second side of the recording medium to the second recording portion.

Abstract: An original image is read, image data corresponding to a black frame is added to the read original image data, and the image data with the frame is output. In this case, when the shape of the read original image data is not a rectangular shape, since the black frame is not added as intended, binarized data of the read image before the image frame is added is directly output.

Abstract: A method and apparatus in which images on the front and back sides of a double-sided original are serially connected on one scanning line, subjected to image processing and converted into binary image data, and immediately separated into the front and back side images again. One of the front and back side images is compressed and transferred to a SCSI bus, and the other is temporarily stored in a graphic video RAM and can be displayed or printed. After the former image is completely compressed and transferred, the latter is read from the video RAM, compressed by the compression circuit and then transferred to the SCSI bus.

Abstract: An image reading apparatus includes image sensors for reading images on the front and back faces of an original, a buffer RAM for storing first image data representing the image on the front face of the original, and second image data representing the image on the back face of the original, which data are output from the image sensors, and an output circuit for selecting and outputting one of the first and second image data read out from the buffer RAM.

Abstract: An image registering method and apparatus for recording an image in a recording medium include reading an image of an original to which a bar code is added, storing the read image of the original in a memory, rotating the image stored in the memory by 90 degrees, detecting the bar code from the image, which has been rotated, and decoding detected bar code information and forming an index file indicating a relationship between the decoded bar code information and a recording address of the image of the original, which is recorded in the recording medium.

Abstract: An image reading apparatus having different reading speeds includes carrying structure for carrying an original at one of first and second speeds, the first speed being lower than the second speed. Reading circuitry is provided for reading an image from at least one of the front face and the rear face of the original being carried by the carrying structure, and for supplying an image signal representing the read image. Control circuitry is provided for changing the speed of the carrying means. In one aspect, the speed is changed depending upon whether one face or both faces of the original are to be read. According to another aspect, a level of the image signal representing the read image is changed depending upon the speed of the carrying structure.

Abstract: An image storing method includes the steps of: reading an image of an original including index information to provide image information; recording the image information on a recording medium; reading out the image information recorded on the recording medium; detecting the index information included in the image information which is read out from the recording medium; and generating an index file showing the relationship between the detected index information and a storage address of the image information recorded on the recording medium. Also disclosed is an image storing apparatus which records on a recording medium image information of an original including index information, which is provided from an image reading device.
