Abstract: A method and apparatus for transferring a strip-form photosensitive paper material comprising mounting a feed roller on an upstream side of an exposure table and a transferring roller on a downstream side of the exposure table and intermittently transferring photosensitive paper material onto the exposure table only in predetermined feed size, characterized by measuring, in advance, a feed size of the photosensitive paper material based on a number of revolutions of the feed roller and a feed size of the photosensitive paper, based on number of revolutions of the transferring roller, and compensating for the number of revolutions given to both rollers in order to prevent an error generated between the photosensitive paper feed sizes and an exposure table having upstream feed rollers and downstream transfer rollers and control means for measuring and feed the photosensitive paper material.
Abstract: The invention relates to a process for the photomechanical production of structured surfaces on a pattern support as an image for an electronically stored original, in particular for exposing offset print plates. The invention further relates to a device for carrying out the process. The original is broken down electronically into partial images which are displayed successively on a liquid crystal screen and reproduced on the pattern support such that the images recombine to form a total image of the original on the design support. The information in a partial image is checked and the partial image is reproduced on the pattern support according to this check.

The recording medium supporting member and the electro-developing recording medium are moved upward and downward by rotating a drive screw, so that one of the first, second, and third recording areas is positioned in the optical path of the photographing optical system. The position of the electro-developing recording medium is adjusted in a horizontal direction by extending and contracting the piezoelectric transducer.
Abstract: An image recording device mounted on an electro-developing type camera using an electro-developing recording medium in which an object image obtained through a photographing optical system is electronically developed. The electro-developing recording medium has a first recording area in which the image is recorded, and a second recording area in which information other than the image is recorded. First and second electrodes are provided in the first and second recording areas, respectively, so that an electric voltage can be independently applied to the first and second recording areas. By exposing the first recording area while applying the voltage thereto, the image is recorded in the first recording area. By heating the second recording area without applying the voltage thereto, the information is recorded in the second recording area.
Abstract: When a recording mode of a printer is changed to a resolution expansion mode when an internal temperature of a recording head falls or by an external indication, the number of divided blocks is changed so that the overlap of on time zones of block sub-division signals is prevented in order to assure that heaters of the recording head are energized for a sufficient time period. Thus, the heater energization time period for each block is extended without extending the total recording time.
Abstract: A motion picture film having digital audio data recorded in at least one sound track thereof. Such digital audio data includes a plurality of bytes of data each having 8 bits of data. Each respective bit of each byte of audio data is recorded in a sound track of the film in the film running direction and each byte is arranged side-by-side in a direction normal to the film running direction to form a compression processing block. C1 parity data is added to each such compression processing block and C2 parity data is added after a predetermined interval of plural compression processing blocks. Error correction may be performed by utilizing the C1 and C2 parity data for each compression processing block and at the predetermined interval of plural compression blocks.
Abstract: A film containing first sections with narrower panoramic frames and second sections with wider normal frames is scanned to obtain density values. To distinguish the panoramic frames from the normal frames, the density values along two longitudinally extending strips near the edges of the film are checked for each film section. Each strip has a length equal to that of the respective frame, and the strips border the narrower panoramic frames but are located within the wider normal frames. The density distribution in each strip is compared with density distributions previously derived from the borders of panoramic frames.
Abstract: An image signal recording operation control device is provided in a still video camera. The control device has a photographing optical system by which an image is formed on an electro-developing recording medium, by which the image is electronically developed. The control device also has a scanner optical system by which the image developed by the electro-developing recording medium is formed on a sensor imaging plane. A line sensor is provided for scanning on the sensor imaging plane to read out the image. When the electro-developing recording medium is not mounted in the still video camera, i.e., when an aerial image formed by the photographing optical system is read by the line sensor, the scanner optical system is displaced by a predetermined amount along the optical axis, in comparison with a state in which the electro-developing recording medium is mounted, so that the scanner optical system can form an in-focus image on the sensor imaging plane.

The density of the printing substance measured by the density measuring unit is either a density of the printing substance representing a predetermined mark which has been printed in addition to printing out received image information or a density of said printing substance representing said received image information. A blockage removal unit is provided for performing a blockage removal operation for removing any blockage which prevents a printing unit from normally printing out the received image information.

Abstract: An electronic still video camera has an electro-developing recording medium. As soon as an optical image is formed on the medium, the image is recorded and developed as a visible image therein. The developed image is electronically read as image data by a line sensor, and the read image data may be stored in an IC memory card, a floppy disk, a hard disk or the like. Optionally, the read image data may be transferred from the camera to an external device such as a computer, a TV monitor or the like. The developed image can be thermally erased from the medium by using an electric heater. One of these operations is executed by a depression of a single switch in accordance with a mode-selection switch.

A photometry sensor is provided behind the electro-developing recording medium to sense the intensity of light passing through the first, second, and third recording areas.

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.
