Abstract: A small, light-weight copying machine which is capable of being carried and which includes none of the bulky components ordinarily found in a copying machine. A light receiving element mounted upon a moving element is manually scanned over an original document. The light receiving element produces an image signal which in turn controls a thermal recording head which records upon a heat-sensitive recording sheet. The thermal recording head and light receiving element are both mounted upon a single moving element with the thermal recording head being stationarily mounted thereon and the light receiving element being movable therealong in a longitudinal scanning direction. The heat-sensitive recording sheet is moved in correspondence with lateral movement of the light receiving element.

Abstract: Facsimile scanning apparatus is provided with two carriages which move in antiphase with one another along parallel rails and respectively scan alternate lines. The two carriages are interconnected by a tensioned inextensible loop passing around a pulley at one end of the rails. The pulley is movable towards and away from the rails so that the phase relationship of the carriages may be adjusted while the apparatus is in use, thus ensuring that the desired 180* antiphase relationship necessary for good facsimile reproduction can be attained quickly and easily.

Abstract: Disclosed are a light scanning unit and a method of synchronizing the scanning operation of such light scanning unit. The light scanning unit includes a deflection mirror that is driven to oscillate so as to deflect and scan a light beam in a bidirectional scanning path. The synchronization of a scanning operation may be made at least in part in consideration of the direction of flow of the current that is supplied to drive the deflection mirror to oscillate.

The scanner may produce bidirectional scanning of light by oscillating a deflecting mirror about a first axis substantially parallel to the mirror surface, and may compensate for skewing of the scan lines by rotating the mirror about a second axis that is substantially perpendicular to the first axis so as to allow the light to be scanned at an angle.

Abstract: In an image-forming method, a device reads line data L for one line and determines whether the resolution of the line data L in the main scanning direction is greater than or equal to a threshold th. If the resolution is greater than or equal to the threshold th, then a multiple line process is performed on the line data L to divide this data into two sets of partial line data L1 and L2. The partial line data L1 and L2 are used to form two lines at locations shifted from each other in the sub-scanning direction. However, if the resolution of the line data L is smaller than the threshold th, then a single line process is performed to divide the line data L into two segments Q1 and Q2. The segments Q1 and Q2 of the line data L are used to form a single line at the same location in the sub-scanning direction by printing the segment Q1 in the first main scanning operation and by printing the segment Q2 in the second main scanning operation.

Abstract: In a multi-stage scanning method for increasing a scanning speed and enhancing an image quality, an optical module is firstly moved from a start position to a forward-internal position in a forward direction, and then enabled to scan a first portion of a document to obtain a first image until the module reaches a forward-boundary position. Then, the module is moved from the forward-boundary position to an end position in the forward direction. Next, the module is moved from the end position to a reverse-internal position in a reverse direction, and then enabled to scan a second portion of the document to obtain a second image until the module reaches a reverse-boundary position. Then, the module is moved from the reverse-boundary position to the start position, in the reverse direction, and then stopped. Finally, the first and second images are stitched into a complete image.

Abstract: A system for determining the return of the photo sensor in the scanner and the method thereof are disclosed. There are two base position sensing units in the system. Each of the base position sensing units computes the currents in two sections of a line resistance material defined by the position of the photo sensor after a document is scanned to determine which base position sensing unit the photo sensor should return to. This method reduces the return time of the photo sensor than the prior art in which the photo sensor can only return to a single end. Therefore, the system helps achieving the goals of increasing the scanning efficiency and saving power. Moreover, the system realizes the image scanning in both directions.
