Handheld barcode code input device with no-power supplied switch trigger
A device for scanning a bar code symbol is adapted to be worn comfortably on an operator's bare or gloved hand, arm, or wrist which does not interfere with normal use of the hand. When provisioned with a glove, a portable bar code scanner means is secured on the back of the glove and is electrically connected to an activation switch disposed at a button provided at the end of a cable for manipulation by a thumb or other finger. The activation switch triggers the portable bar code scanner means to scan a bar code symbol to be read.
1. A bar code input device, comprising:
a bar code scanner means having a ground signal-based activation circuit for detecting a ground signal;
an attachment means for attaching said bar code input device to a body of an operator within a general vicinity and at in a general direction of a bar code symbol to be scanned by said bar code scanner means during a scanning operation, said attachment means further being situated on an operator's body so as to not to interfere with normal use of hands of said operator; and
a no-power supplied trigger means connected to said bar code scanner means for activating said bar code scanner means, wherein said trigger means includes a ground signal-based activation circuit for completing said ground signal-based activation circuit and a push button that, when depressed, provides a ground signal that is detected by said bar code scanner means for no-power supplied activating of a scanning operation by said bar code scanner means.
2. The bar code input device according to claim 1 , wherein said attachment means comprises a glove adapted to be worn on a system operator's hand.
3. The bar code input device according to claim 2 , wherein said no-power supplied trigger means actuates said ground signal so as to turn on said bar code scanner means continuously for a fixed time until a good bar code read occurs during a given said scanning operation.
4. The bar code input device according to claim 3 , wherein said bar code input device includes at least one battery unit and wherein said no-power supplied trigger means extends a power of said at least one battery unit and further comprises a coupling means for coupling said push button to said bar code scanner means.
5. The bar code input device according to claim 4 , wherein said coupling means further comprises a hard-wired connection.
6. The bar code input device according to claim 4 , wherein said coupling means utilizes a radio frequency medium.
7. The bar code input device according to claim 5 , wherein the bar code input device is adapted for both ambidextrous and hands-free operation and is further adapted so as to provide an ergo-dynamic, changeable positioning of said trigger means so as to reduce repetitive stress injuries.
8. The bar code input device according to claim 7 , wherein the glove adapted to be worn on a system operator's hand further includes a flexible cover for cushioning and snag prevention.
9. The bar code input device according to claim 4 , wherein said coupling means further comprises a trigger line paired with a ground line, through a pairing up of pin interfaces of male and female connectors.
