    Abstract: There is provided a multiimage forming apparatus for forming image data onto photo sensitive drums by an electrophotographic system. This apparatus comprises: an image forming circuit to form different images onto the photo sensitive drums; a transfer device to transfer the images on the drums onto the same transfer paper; a conveying belt to convey the transfer paper; a control circuit to control the image forming circuit so as to form registration marks (34,35) to match the positions of the images onto the drums; CCD detectors (14,15) to detect the recording positions of the marks (34,35); and a correcting circuit to correct at least two of the positional direction in the conveying direction of the belt, the positional deviation in the direction perpendicular to the belt conveying direction, the magnification of the image, and the inclination of the image on the basis of the detection outputs of the detectors (14,15). With this apparatus, the positional deviations of the images which occur during the image formation can be accurately corrected, so that the images can be accurately formed on the transfer paper by reading and matching the position matching registration marks (34,35).

    Abstract: A data processing system, in which image data is transmitted in units of predetermined length, e.g., a predetermined number of lines, and code data comprising a character or the like, is transmitted in units each of which contains the code data corresponding to the predetermined unit of the image data. The image and the code data are preferably transmitted on a common transmission channel, and can be separated upon reception for separate processing.

    Abstract: The soft-surfaced pressure roller is pressed vertically against a hard, heated roller - or vertically between two hard, heated rollers - when fixing is in progress. The present arrangement reduces this pressure while leaving the rollers in light contact and rotating at all other times. The driving gear of the lowest of the rollers is mounted on a pivoted frame on which it can drop down from the other rollers. It is raised when required on a pair of gear wheels mounted on a pivoted arm. When the pressure is required, an electrically operated clutch first holds the lowest of the auxiliary wheels on its axle - on which, till then, it had been free to turn. The drive on the raising wheel, which is in mesh with this lowest wheel, now turns the pivoted arm, raising the roller's driving gear on its pivoted frame.

    Abstract: A support structure (3) for supporting a display apparatus (2) which can be tilted vertically upwards or downwards from a predetermined position, is disclosed. This support structure has a tilting mechanism (10) providing a differential torque reaction to an applied tilting force to accommodate a difference in the applied torques required when tilting upwards against the weight of the display apparatus (2) and when tilting downwards assisted by the weight of the display apparatus (2), respectively. In the preferred arrangement, the differential torque reaction is provided by a fixed helical spring (13) and a horizontal axis member (12) at each end (10r,10l) of a support arm (8) provided for supporting the display apparatus (2) on the support structure (3).
