When the mouse is in proximity to the bar code on the surface over which is tracks, switches on the mouse are actuated and circuitry in the mouse associated with the device and with the scanning engine initiates scanning, and provide outputs representing the location of the mouse on the surface and the bar code. The circuitry may be adapted to enable bar code scanning only when the mouse is located at selected positions on the surface where bar codes are expected to be found. The entire mouse assembly may be lifted from the surface and operated in a manner similar to a tethered hand-held bar code scanner using switches and scanner engine.

DETAILED DESCRIPTION Referring to FIGS. 1 and 2, there is shown an integrated bar code reader and location detection apparatus having a shape and size of, and operative in a manner similar to, a computer mouse. Accordingly, it is referred to as a bar code reading mouse 10. The mouse 10 has a housing 12 having top and bottom parts 14 and 16, which may snap together along a horizontal parting joint (not shown). The upper part of the housing 14 defines a top of the mouse 10 and the bottom part 16 defines the bottom of the mouse. The top has a pair of keys 18 and 19, the location of which is shown by the dash line boxes in FIG. 2. These keys operate electrical switches (SW.sub.1 and SW.sub.2) (see FIG. 3). The bottom of the housing 12 has pads 20 that space the housing from a surface 22 on which bar codes appear. The spacing is such that a ball 24 of an incremental encoder 26 contacts and engages the surface 22 and can roll universally as the mouse is moved in any direction along the surface 22.
In a first mode of operation, the mouse is tracked along the surface 22 to the proximity of a bar code. Then SW.sub.2 is actuated by operating the key 19 to provide an output through the interface to the terminal indicative of the location of the mouse in scanning position with respect to a selected code on the surface. Then SW.sub.1 is actuated by the operating key 18 and the bar code scanner is enabled to provide a bar code signal output through the interface to the terminal, with processes an/or displays the output or a code corresponding thereto ro may store that code in a memory associated with the computer in the terminal.
In another mode of operation of the device, the computer is programmed (information being stored in its memory/database) as to the position of bar codes on the surface to be read. Then outputs are provided by the computer in response to location information from the encoder 26 relayed to the computer via the interface 40. The computer generates an output that, alternatively to SW.sub.1, enables the bar code scanner 36 to scan the code. Then only selected codes on the surface will be scanned. Also the mouse may be lifted from the surface 22, pointed at a bar code (say on a package) and SW.sub.1 operated to scan and read the bar code. Thus, the mouse is operative even when it is not placed on the surface 22 or another surface (e.g. the surface of the package).
