Abstract
Abstract Improved optical wand scanner for the bar code reading, particularly for the data collecting in several applications in the shops and warehouses, by the bar code reading or the optical characters recognizing (OCR). According to this invention, the optical wand scanner is an autonomous wand scanner which isn't connected to any other appliance and comprises means for the reading, codifying and controlling of the data represented by bar codes or OCR, storage means for the inputted data, means for the connection to a processor for transferring the stored data into it, control means, means for the autonomous voltage supply, data manual inputting means and display means forthe manually inputted data.

Claim 5
Dependent Claim
47 words
Optical wand scanner according to claim 1, characteri zed in that the means for the mechanically connection of the wand scanner to the processor are constituted by a comb connector, a spring receptacle connected to the pro cessor and a plastica cover for protecting the comb connector.
Claim 6
Dependent Claim
32 words
Optical wand scanner according to claim 1, characterized in that it comprises a microprocessor and an EPROM memory, both realized in the form of integrated circuits, for controlling the whole unit working.
Claim 7
Dependent Claim

Optical wand scanner according to claim 1, characterized in that the means for the unit operating state outside signaling are constituted by an acoustical signal emitter for alternatively indicating: - the correct reading, - the full-stored memory, - the erasing of the last introduced datum, and by luminous indicators for respectively indicating: - the wand scanner operation (after having depressed the key), - the erasing of the last introduced datum.
Claim 9
Dependent Claim
37 words
Optical wand scanner according to claim 1, characterized in that their autonomous voltage supply means are con stituted by a rechargeable Nickel-Cadmium cell or equivalent, which is automatically rechargeable when the data are transferred into the processor.
Claim 10
Dependent Claim
35 words
Optical wand scanner according to claim 1, characterized in that it comprises means for data manual input and visualizing, constituted by a spring key having a short working path and by five luminous indicators (LED).
Claim 11
Dependent Claim
