摘要： A scanning device for projecting a light beam against a target having information contained thereon which is to be scanned by the light beam; and in particular relates to a compact laser scanning device, such as a bar code projecting a laser beam, and which device incorporates a drive component such as a scanning motor for oscillating a scanning element or mirror at a high rate of speed within a specified angular range so as to cause the light or laser beam which impinges against the information on the target to be rapidly swept across the information in a scanning sequence. In particular, the structure is directed to improving the linearity of the oscillatory or "dithering" motion imparted by the scanning motor to the scanning element or mirror. Also contemplated is a novel method of utilizing the "dithering" or oscillating motion of the scanning motor for effectuating an improvement in the quality of the scan by the scanning device.

摘要： A compact beam scanning information readout device and method for reading bar code or other information requires little or no orientation of the information to be scanned by virtue of its raster or omni directional scan capabilities. Only a single mirror is needed to generate two dimensional scans. A wide range of scan speeds are also possible for simple or complex one or two dimensional patterns. Scanning in two dimensions may be done with independent and continuous control of the scan in each dimension. The scan patterns may be electronically controlled to instantly achieve various orientations ranging from a straight line rotated about a point to continuously rotating complex patterns. A light collector, light detector, processor, and means of signal transmission are also included. In one embodiment the device is packaged in a housing resembling a wand or a thin flashlight and in another embodiment the device is packaged in a ceiling mountable housing which will not interfere with counter top work space. The invention is useful wherever beam scanning equipment is used especially for barcode scanning, pattern recognition, general beam positioning, and many other scanning applications.

摘要： A miniature device for moving a reference plane or point on an axis in rotational or x-y directions, particularly useful for two dimensional beam scanning. The device consists of a ferromagnetic ring surrounding a magnetic core which is flexibly mounted and suspended within it. Electric current at various frequencies is supplied to coils wrapped about and mounted within the ring. The core provides a magnetic field within the ring which defines its coordinates with respect to the ring and its coils and interacts with current applied to the coils to produce torque. The flexible mount suspending the core within the coils permits relative movement therebetween in response to the varying current.
