摘要:
A wall-mounted, hands-free scanner capable of having its field of view adjusted using a pivot structure with a position-holding mechanism. The spacing of the field of view from the wall can be quickly adjusted to accommodate different size objects and different placement of indicia on objects. The scanner includes a base member configured to be installed on a vertical surface, a scanning unit including a light scanning source directing a light beam across a field of view toward an indicia located within the field of view, a pivot structure connecting the scanning unit to the base member (the pivot structure having a generally horizontal axis of rotation about which the scanning unit rotates relative to the base member), and a position-holding mechanism within the pivot structure. The scanning unit may be rotated relative to the base member to adjust the spacing of the field of view from the vertical surface, and the position-holding mechanism within the pivot structure maintains the scanning unit at a selected angular position. No tightening or other position-holding step is required following adjustment of angular position.

A bezel display for a currency acceptor that displays a pixelated image of the last bill accepted by the validator to show the player what was inserted. When not displaying the last bill accepted, the display can be used as an aesthetic addition, and when a fault occurs in the acceptor, it can display in multiple languages what is causing the fault, as well as display images showing where the fault has occurred.

An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.

An RFID reading apparatus includes a frame. The RFID reading apparatus also includes an RFID interrogator, coupled to the frame, for triggering transponders in picked cases and receiving and decoding replies. The RFID reading apparatus further includes at least one vertically movable antenna mount coupled to the frame, at least one antenna mounted to the antenna mount and coupled to the interrogator, and at least one object sensor adjacent to at least one antenna. The RFID reading apparatus also includes a control unit coupled to the interrogator for initiating interrogation of transponders and accepting decoded replies, to the antenna mount for controlling the level of the antenna mounted on the mount, and to the object sensor for detecting the presence of cases adjacent to the object sensor.
摘要:
Apparatus for reading RFID tags of picked goods as they are loaded onto a picked pallet, and a method of picking and tracking goods using the device. The invention is mounted on a pallet support on a pallet conveyance, and has an RFID interrogator connected to at least one antenna mounted on a vertically movable antenna mount. The interrogator triggers the transponders in the goods and sends the decoded replies to the control unit. An object sensor adjacent to the antenna senses the presence of goods, and a control unit controls the movable antenna mount to raise the antenna mount above the goods. A computer having a display visible to an operator loading the pallet conveyance is used to communicate with the operator, confirming the loaded goods are the correct ones, and tracking inventory loaded on the conveyance. A barcode reader may be located on the antenna mount.

An embodiment of the invention may include an apparatus. The apparatus may include a channel configured to accommodate a note, a photodetector array preferably arranged substantially perpendicular to a direction of travel of the note through the channel, a transporter configured to transport the note through the channel, at least one illuminator configured to illuminate a width of the channel, and a lens associated with the photodetector array. The lens and the at least one illuminator may be arranged to provide optical data collected from the width of the channel to the photodetector array. The photodetector array may include a plurality of photodetectors.
摘要:
To reduce the size and weight of an optical scanner, the present invention provides a mirrorless beam scanning unit. A flexible member, such as a multi-wire, flat, electrical cable is connected to the light emitter. Reciprocation of the light emitter during emission of light by the light emitter causes the light to scan a surface, such as a surface bearing a bar code label. The cable flexes during such reciprocation.
摘要:
A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.
