Icons/text/images representing selections areas are placed near a machine readable image to for retrieving an information item about a product to which the machine readable image is associated. These selection areas can be visually represented by icons/text/images that inform the user what information will be retrieved or what action will be controlled if selected. A capturing device captures a machine readable image together with icons/text/images representing selections areas, displays these on the screen for the user to select one of the icons/text/images. The capturing device calculates the coordinates of the selection relative to the machine readable image using a unit of distance and perspective correction derived from the machine readable image. These coordinates are provided to an information server associated with the machine readable image which in turn provides the information associated to the coordinates to the capturing device.
摘要:
A bar code reader having two reading windows, i.e., a bottom window and a side window. An increased number of scanning lines are used for constituting scanning patterns for scanning bar codes, and the arrangement of the optical system is contrived to decrease the whole size of the bar code reader and, particularly, to decrease the depth of the bar code reader. A source of laser light, a splitter for splitting the laser beam emitted from the laser light source into two, a reflection mirror for transmitting one beam from the splitter to a polygon mirror, the polygon mirror which rotates to scan the incident laser beam, a mirror system for emitting the beam reflected by the polygon mirror through the reading window, and a focusing member for focusing the beam reflected by the bar code onto a detector that detects the beam reflected by the bar code, are arranged on the same line in the bar code reader. By using a concave mirror, furthermore, the beam reflected by the bar code is folded back to one detector. The light-receiving surface of another detector is faced downward to receive the beam reflected by the bar code through Fresnel lens and mirror, thereby to decrease the depth of the bar code reader. Furthermore, the beam passage from the reflection mirror goes through the lower surface of the polygon mirror intersecting the axis of rotation of the polygon mirror.

摘要:
An improvement is made to a scanning device to increase item throughput at the point of sale (POS). The scanning device implements a mirror that allows a cashier to see hidden or obscured optical codes or bar codes on items. The mirror can reflect an aiming beam from a camera, which also allows the cashier to correctly scan the optical codes or bar codes. The mirror and camera can incorporate different properties to enable both the cashier and a customer to stand on opposite sides of the scanning device and scan items.

Tube holders for use in a lab environment include an optical device to allow the observation of barcode information on a sample tube. The optical device can include a lens or camera. Tube holders can also include reflective surfaces or mechanical mechanisms to allow the tube to be rotated such that reading a barcode does not require a strict initial orientation of the tube when placed in the tube holder. Arrays of tubes can include optical guides to allow barcodes to be read by an external imaging device.
摘要:
A dual aperture optical scanner which produces horizontal, vertical, and diagonal scan patterns. The optical scanner includes a housing having a substantially vertical surface containing a first aperture and a substantially horizontal surface containing a second aperture. A laser diode produces a laser beam. A spinner produces first, second, and third groups of scanning beams. A plurality of pattern mirrors reflects the first group of scanning beams in a substantially horizontal direction through the first aperture, the second group of scanning beams in a substantially downward diagonal direction through the first aperture, and the third group of scanning beams in a substantially vertical direction through the second aperture.
