Abstract:
An apparatus and method for translating a printing element (500) relative to a frame (202) has a wear resistant coating on translational rod bearings (206,208) which support the element, such as a scanner, for slidable movement along a frame. Titanium nitride is coated over a hardened stainless steel core of the translational rod bearings and bearing pads (610,660) which are arranged for sliding contact with the translational rod bearings. The bearing pads comprise diamond laminated tungsten carbide (616).

Abstract:
A device for reading graphic symbols impressed on a sheet, comprising light sources for illuminating the sheet, an optical reading system and an array of photo-electric sensors for generating electrical reading signals. The device is compact in structure and of small dimensions, so as to allow it to be mounted upon the head-carrying carriage of a printing machine or typewriter. The device makes it possible to create, in a particularly simple form, reading apparatus for facsimiles or for optical character recognition (OCR) reading apparatus for memorizing signatures, graphical symbols and drawings or mathematical symbols, or apparatus for copying documents.

Abstract:
An automatic document feeder composed of a transparent sliding platform, side guides, longitudinal guides and a horizontal guide, a system of springs, a controller, a linear actuator, a protection bar, a rigid part, a set of bushings, bearings, document detection and motion sensors, and an end position sensor, a linear spring, a bobbin and a motor. The automatic document feeder can also be adapted to all types of document reader and reads flat and bulky documents alike. An operating method of the automatic document feeder is also disclosed.
Abstract:
A document reading device is capable of preventing distortion or twisting occurring in a document conveying device from being transmitted to a reading carriage incorporated in the document conveying device. A document reading device includes a second reading carriage provided in a document conveying unit and configured to read a surface of a document different from a surface read by a first reading carriage, a support frame having a support surface supporting the second reading carriage, a retaining member retaining the second reading carriage by sandwiching the same between itself and the support frame, and an elastic member provided between the second reading carriage and retaining member to press the second reading carriage against the support frame. One of the support surface of the support frame and a supported surface of the second reading carriage supported by the support surface is formed into a curved surface.
Abstract:
An image scanning apparatus includes a document holder and a scanner module movably installed in the document holder, A multi-function apparatus may further include the image scanning apparatus. While the scanner module passes over the lower side of a document guide provided between a first glass and a second glass provided at the document holder, spacers installed at opposite ends of the scanner module are moved downward by guide members provided at the document guide, thereby preventing spacer portions provided at an upper end of the respective spacers from being caught by the document guide.
