摘要:
An optical scanning system for reading indicia of differing light reflectivity has an optical scan module which is adapted to be mounted on a finger of a user. A first peripheral module, preferably in the form of a wrist watch, has a receiver which detects the reflected light. A second peripheral module, mounted on the other arm of the user, communicates with the first module by radio frequency transmission. According to other aspects of the invention, the light detector may be mounted in a housing which is separate and part from the optical scan module. According to another aspect, a laser pointer or scanner is mounted to a ring which is arranged to be worn on a single finger of the user.

Commercial transactions are expedited at a point-of-transaction site by providing a customer with advance notification of the price of selected goods, by providing the customer with a portable, integrated reader/terminal unit having an on-board display on which the price of the selected goods is displayed in response to a manual action on the part of the customer holding the unit.

A system for transferring data between a centrally located site and a portable communications terminal via a telephone network, the site having associated therewith a look up table containing plurality of data records correlating to items disposed at a retail establishment, wherein each of the items has associated therewith a bar code encoded with the indicia unique to each item, with each of the bar coded indicia corresponding to a particular record in the table, the data containing at least a portion of said record.

An optical reader for reading a target having a bar code to be read, in which a unitary semiconductor device is mounted in a housing having an opening. The unitary semiconductive device includes a semiconductive substrate and a plurality of integrated components at the surface of the semiconductive device for generating and directing a light beam outward from the surface of the substrate sequentially along a plurality of paths through the opening of the housing. A detector is disposed in the housing for intercepting reflected components of the outward-directed light beam. In two implementations, the light beam is directed respectively by a single movable reflector or by a plurality of deformable mirror devices mounted on the substrate. The housing includes a grip, such a pistol grip, at an extremity offset from the opening.

A microfilm reader, which includes a bar code scanner, a controller, and a keyboard, receives microfilm containing documents and corresponding bar code symbols. Each bar code symbol contains data describing the contents of a respective document. The bar code scanner reads the bar code symbols located on the microfilm and transmits data representing the read bar code symbols to the controller. The controller determines whether the data received from the bar code scanner satisfies search criteria entered into the keyboard.

A handheld data entry terminal includes a housing and a scanning head mounted to the housing for pivotal movement between at least first and second reading positions. The scanning head, when actuated, optically scans an encoded symbol and detects light reflected from the encoded symbol while in either of the first and second reading positions. As desired, a terminal user can establish either one of first and second trigger switches mounted to the housing as a scanning head actuating switch, leaving the other of the trigger switches to be established as a shift key for determining the type of characters entered by alphanumeric data entry keys of a keypad also mounted to the housing in conjunction with an LCD display.

In bar code symbol scanning systems employing laser, optical and sensor components, a mirrorless scanner arrangement mounts one or more of these components on a drive for repetitive reciprocating movement either about an axis or in a plane to effect scanning.
