Abstract

An independent, stand-alone, battery powered information display module to visually display computer generated, alpha-numeric information on one or more liquid crystal displays. The module has particular application for storing and displaying pricing and related information associated with a shelf item commonly offered for sale in a retail establishment, such as a grocery store, or the like. Pricing information is supplied by a computer to the price display module for storage and eventual display by way of a hand-held, portable data terminal. The portable data terminal is electrically connected to the display module by a multi-terminal connector, whereby electrical contact pins of the connector are aligned for engagement with respective electrical contact strips located at the face of the display module and connected to the memory thereof. A multi-conductor electrical cable extends from the contact pins of the connector to be coupled to the portable data terminal to permit the two-way transfer of information between the memory of the display module and the computer.

Claims

1. In combination,

an information display device having

(a) a housing defining spaced edge surfaces on the exterior thereof,

(b) a memory connected to said housing for storing information,

(c) display means connected to said housing and interfaced with said memory for visually displaying the information stored therein, and

(d) first electrical contact means on the exterior of said housing and operatively connected to said memory;

and

a portable data terminal for supplying information to said memory, said terminal including,

(e) a face for presentment to the housing,

(f) second electrical contact means on said face engageable in abutting relationship with said first contact means,

(g) guide means on said terminal adjacent said face and operable in cooperation with said edge surfaces as said face is presented to said housing to guide the position of said face so that said second electrical contacts come into abutting electrically conductive relationship with said first contacts.

2. The combination recited in claim 1, wherein said display means has a switch interconnected therewith, the activation of said switch changing the information displayed from certain information stored in the memory of said information display device to certain other information stored therein.

3. The combination recited in claim 1, wherein said information display device also has a picture attached thereto of an item to which the information stored in the memory of said display device relates.

4. The combination recited in claim 1, wherein the first electrical contact means of said information display device comprises a plurality of electrically conductive strips extending along said housing and interconnected with the memory.

5. The combination as in claim 4, wherein the second contact means of said terminal comprises a plurality of electrical contact elements that are aligned for engagement with respective ones of said plurality of conductive strips when said terminal face is presented to said housing.

6. In combination,

a shelf for support products,

an information display device mounted on said shelf and having

(a) a housing defining spaced edge surfaces on the exterior thereof,

(b) a memory connected to said housing for storing information,

(c) display means connected to said housing and interfaced with said memory for visually displaying the information stored therein, and

(d) first electrical contact means on the exterior of said housing and operatively connected to said memory;

and

a portable data terminal for supplying information to said memory, said terminal including

(e) a face for presentment to the housing,

(f) second electrical contact means on said face engageable in abutting relationship with said first contact means, and

(g) guide means on said terminal adjacent said face and operable in cooperation with said edge surfaces as said face is presented to said housing to guide the said second electrical contacts come into abutting electrically conductive relationship with said first contacts.

7. The combination as in claim 6, wherein the first electrical contact means of said information display device comprises a plurality of electrically conductive strips extending along said housing and interconnected with the memory.

8. The combination as in claim 7, wherein the second contact means of said terminal comprises a plurality of electric contact elements that are aligned for engagement with respective ones of said plurality of conductive strips when said terminal face is presented to said housing.
