摘要： A scrolling apparatus is disclosed that includes a rotatable scroll wheel and a sensor assembly coupled mechanically through a flexible cable. The sensor assembly has an encoder wheel that rotates in response to rotation of the scroll wheel. The rotational axis of the encoder wheel is axially displaced from the rotational axis of scroll wheel, and the diameter of the encoder wheel may be greater than the diameter of a conventional encoder wheel. The differences in diameter of the scroll wheel and encoder wheel may be utilized to provide the scrolling apparatus with relatively high resolution. In addition, the flexible cable permits the scroll wheel to be mounted within a tilting mechanism.

摘要： An imaging lens unit has an imaging lens and an integral holder for a light source such as a LED. The imaging lens unit can include a body portion, with the imaging lens being formed as an integral part of the body portion, together with a light source support fixture also formed as an integral part of the body portion. The support fixture supports a light source in a desired spatial relationship with respect to the imaging lens, and may have an opening for insertion of the light source into the support fixture along an installation axis. The fixture may be configured to prevent removal of the light source along substantially all other axes. The light source support fixture can be configured to support and retain the light source without additional cooperating structure. The invention further includes a computer mouse having an imaging lens unit with an integral light source support.

摘要： An image recording system typically having a fixed lens system for easily recording a focused image of an object. The image recording system includes light beam sources directed such that when the projections of their light beams onto the object overlay each other, the object is positioned at the correct distance from the image recording system to project a focused image onto the image recording medium. Additional pairs of light beam sources are added to the image recording system to provide for rotational alignment of the image recording system with the object. The system can be fabricated as an inexpensive document recording system.

摘要： A position sensing device for determining the position of an object to which the position sensing device is attached is disclosed herein. The position sensing device may comprise a substrate, an actuator and a two-dimensional photosensor array wherein the substrate is attached to the object. The actuator may have a first portion and a second portion wherein the actuator first portion is attached to the substrate and wherein the actuator second portion is movably mounted to the actuator first portion along a first axis. The two-dimensional photosensor array may be attached to the actuator second portion. The position sensing device determines the position of the object by electronically and mechanically tracking distinct features on the surface. The electronic component of the tracking involves determining the position of the distinct features relative to the two-dimensional photosensor array. The mechanical component of the tracking involves moving the two-dimensional photosensor array to track the distinct features.

摘要： Hand-held image scanner apparatus may comprise a body having first and second side walls positioned in spaced-apart relation so that the second side wall is located a spaced distance from the first side wall. The body also includes a convex face portion that extends between the first and second side walls and defines a contact axis that extends along a lateral direction and that is located longitudinally between the first and second side walls. The convex face portion allows the body to be tilted about the contact axis when the convex face portion is in contact with an object to be scanned. An image sensing system mounted within the body is responsive to image light reflected by the object being scanned and produces an image signal based on the image light. The image sensing system is optically coupled to an image light opening in the convex face portion of the body so that image light passing through the image light opening is received by the image sensing system.
