Abstract

Alternate configurations for a hand-held portable device that scans and prints are disclosed. The device, with full page width scanning, produces a copy by passing over input and output respectively. Scanned data is accumulated while passing the device over the surface of an input document. The scanned data is either transmitted to an attached computer or other device, or retained in a full page buffer within the device. After the device is converted from input to output operation, scanned data is printed as the device is passed over a receiving sheet.

HAND-HELD SCANNER AND PRINTER CONFIGURATIONS (Cont'd)

Alternate configurations for a hand-held portable device that scans and prints are disclosed. The device, with full page width scanning, produces a copy by passing over input and output respectively. Scanned data is accumulated while passing the device over the surface of an input document. The scanned data is either transmitted to an attached computer or other device, or retained in a full page buffer within the device. After the device is converted from input to output operation, scanned data is printed as the device is passed over a receiving sheet.

Figure 1 shows three possible configurations (A, B and C) of image bar 2, a hand-held device that scans and prints. Image bar 2 has at least one edge 5 for sliding over the surface of a sheet of paper 8. A motion correction system (not shown) located along edge 5 detects and measures motion of bar 2 at two points over the surface of sheet 8 in order to correct variations caused by holding image bar 2 by hand. Rollers 10 are used for movement of image bar 2 along sheet 8. More rollers, however, may be required on both sides to ensure bar 2 has adequate perpendicularity to the surface of sheet 8. Figure 1A shows input device 12 and output device 14 on separate substrates and positioned along edge 5 of bar 2. The input and output devices 12 and 14 are composed of a page width strip of silicon or thin film circuitry on another substrate material such as glass. Input device 12 has input sensors...
