  • Patent number: 6234395
    Abstract: In an exemplary embodiment, a hand held bar code reader has a handle portion and a reader head portion which may be held spaced from a bar code data carrier during a reading operation. Light energy is directed outwardly through a window so as to illuminate a bar code sensing region in front of the window having a depth dimension of at least about ten millimeters, and an optical system focuses bar code patterns in the sensing region onto an image photosensor in the reader unit with a resolution so as to read e.g. bar code formats with a minimum bar or space width of about 0.0075 inch or less. The bar code image is converged through a generally rectangular optical aperture and is reflected onto the image photosensor by a reflecting mirror positioned relative to the image photosensor by virtue of their common association with a printed circuit board.

  • Patent number: 5241488
    Abstract: A hand-held portable data collection terminal is encased by an elongate housing of generally rectangular outline. The housing includes upper and lower housing shells which are assembled into a water tight housing. The upper housing shell may support on an upper surface a display and a keyboard with typically alpha-numeric keys. The area taken up by the display and keyboard defines an overall width of the data terminal which may exceed the width of a readily hand fitting grip. The terminal consequently includes in its lower housing shell a grip-conforming inwardly displaced lower wall bounded by inwardly converging angled sidewalls. The inwardly displaced region at the bottom of the housing is spanned by a resilient strap disposed longitudinally across the grip-conforming portion. A user may insert a hand into a space defined between the strap and the inwardly displaced surface.

  • Patent number: 5187356
    Abstract: In an exemplary embodiment, a hand-hald bar code reader has an elongated relatively narrow hand grip portion and an enlarged reader head portion with an extended window of greater width that the hand grip portion. Light energy is outwardly through the extended window so as to flood a bar code sensing region in front of the window having a depth dimension of at least about ten millimeters, and an optical system focuses bar code patterns in the sensing region onto an image plane in the reader unit with a resolution so as to read bars/spaces with a minimum width of about 0.0075 inch, or even less. Preferably the lens system provides a depth of focus for such bar code patterns of at least ten millimeters, so that a bar code pattern of marked curvature can be read in its entirety by means of an instant reading operation.

  • Patent number: 5180232
    Abstract: Basic elements of a modular printer system may comprise a rectangular open frame with receptacles for a printer module and computerized terminal module, and with an external configuration for receiving modular components such as a carrying handle, a support foot, an auxiliary terminal module mounting bracket and an AC adaptor module. Respective different paper tray modules may be selectively secured to the open frame to form a bottom closure and to provide a repository for appropriate circuit boards and an on-board battery if needed, as well as containing an appropriate supply of paper for the printer (e.g. 50 sheets or 200 sheets). Respective terminal adaptor modules may secure different generations of computerized terminals in the frame for data transfer to the printer. A terminal module may utilize a spring-urged retainer for retaining a hand-held computerized terminal therewith.

  • Patent number: 4953113
    Abstract: In a exemplary computerized FM Data Transceiver terminal, an antenna may extend longitudinally from one end and a battery drawer at an opposite (lower) end may receive a detachable bar code scanner module or the like for mechanized data input. In such computer terminals which are hand-held for relatively long time periods, e.g., during inventory data collection, use of the terminal is particularly facilitated by indenting the underside of the terminal intermediate its ends to form a hand grip configuration and by providing a strap spanning the indentation such that the fingers of one hand can be inserted between the hand grip and strap in a quick smooth motion without requiring as a separate motion the lifting of the strap to accommodate the fingers. These features coact to provide for an outstandingly comfortable and secure gripping of the terminal during use.
