Abstract:
A device capable of printing and scanning using a single roller to accomplish both tasks in which:the printing is accomplished through the use of a printer with a thermal print head which prints a single line of dots parallel to the roller;the said printer prints on thermal sensitive paper which is sandwiched between the roller, which is fixed, and the said thermal print head such that the said thermal sensitive paper moves in a prescribed first direction;a scanner with a scan head which senses a linear array of dots at a time parallel to the roller, is situated on the opposite side of the roller to the printer;the scanner senses dots that are located on an original when the original is pressed against the roller by the scan head, which is springed against it allowing scanning in two dimensions as paper is moved by the roller such that the original moves in a direction opposite to the prescribed first direction;a single drive roller is used for the scanning and printing functions without the reversal of the single drive roller to accomplish these tasks individually at separate times or simultaneously;in its upright operating mode the base is narrow compared to the height making the device unstable in this position;arms that follow the contours of the ends of a main body when closed are pivoted at each end to rotate into an open position to provide necessary support during operation;the said arms when opened tilt the device at an angle to facilitate feeding of the original document through the device from one side without obstruction from a print media roll on the other side;the said arms have protrusions that interface with matching cavities on the main body to keep the arms fixed into an opened position and also a closed position.
