Imaging device // 2635038
FIELD: physics.SUBSTANCE: imaging device includes a body; a fixing element installed in the body and fixed against the body; a shaft supported movably in the axial direction on the fixing element; a paper feeding roller installed and fixed to one end of the shaft. The device includes a locking device installed on the other end of the shaft so that the shaft is rotatable relative to the locking device, and the locking device moves in the axial direction as the shaft moves in the axial direction; a return spring wound around the shaft and configured to be compressed, when the locking device is moved in the axial direction so that the shaft returns to its original position, when the spring is returned to its original position.EFFECT: solution prevents contamination and damage to the paper feeding roller to ensure easy operation by the user, improves the image quality and reduces the paper jam frequency, and also reduces the paper feeding roller wear.9 cl, 11 dwg

Newspaper scanning device and method // 2369487
FIELD: printing industry.SUBSTANCE: newspaper scanning device consists of a supplying sub-system and a scanning device. The supplying sub-system includes a newspaper supplying device, and an automatic supply tray and module. Newspaper supplying device consists of a receiver and a cutter. Receiver is made with the possibility of loading a newspaper in its initial form, i.e. in the form of a set of two-folded sheets put one into the other, passing the loaded newspaper through the cutter made with the possibility of separating the edge of the sheets at the point of their folding, and supplying the final set of single sheets to the tray adjacent to automatic supply module. The latter, in its turn, is made with the possibility of supplying the sheets from the tray one by one to the scanning device.EFFECT: scanning in order of movement of newspaper sheets, reducing manual labour volume, and reducing the time required for scanning one page.17 cl, 3 dwg

Way of forming of symbols for microprinting // 2365510
FIELD: physics, computer technology.SUBSTANCE: invention concerns area of computer technology and can be applied in the user colour and black-and-white printers and multipurpose printers. The way of forming of symbols for microprinting includes definition of the suitable font size for each symbol of the image considering rules of forming of small fonts. Also symbol rasterisation in a bit card is performed, a bit card is skeletonised, a bit card is reformatted with preservation of symbol legibility, semitoning cells of the reformatted bit card are formed.EFFECT: dilation of a scope and improvement of convenience of using at the decreased volume of used memory.8 cl, 15 dwg
